Creating Vertical ScrollView inside ViewPager

I am trying to add a scrollView inside my ViewPager so I can scroll left and right as well as down if the page becomes full. As of now, I am dynamically adding views to my ViewPager:

Fragment Page in ViewPager:

ScrollView is not being inserted since i must remove the parent view.

@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {

    mainView = View.inflate(getActivity(), R.layout.fragment_profile_personal_records, null);
    LinearLayout mainLayout = (LinearLayout) mainView.findViewById(R.id.layoutPR);
    ScrollView scrollView = new ScrollView(getActivity());
    scrollView.setLayoutParams(new LinearLayout.LayoutParams(ViewGroup.LayoutParams.MATCH_PARENT, ViewGroup.LayoutParams.MATCH_PARENT));

    for(int i = 0; i < 3; i++){
        LinearLayout rowLayout = (LinearLayout) mainView.inflate(getActivity(), R.layout.row_personal_records, null);
        mainLayout.addView(rowLayout);
    }
    scrollView.addView(mainLayout, new LinearLayout.LayoutParams(ViewGroup.LayoutParams.MATCH_PARENT, ViewGroup.LayoutParams.MATCH_PARENT));

    return scrollView;
}

XML for Fragment:`

    <LinearLayout
    xmlns:android="http://ift.tt/nIICcg"
    xmlns:tools="http://ift.tt/LrGmb4"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:id="@+id/layoutPR"
    android:orientation="vertical"
    tools:context="test.test.test.fragment">
</LinearLayout>

Container that contains viewPager:

   <LinearLayout
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:orientation="vertical"
    android:layout_below="@id/mainLayout">

    <android.support.v4.view.ViewPager
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:id="@+id/vpPager"
        android:scrollbars="vertical">

        <android.support.v4.view.PagerTabStrip
            android:layout_width="match_parent"
            android:layout_height="wrap_content"
            android:id="@+id/pagerHeader"
            android:layout_gravity="top"
            android:paddingBottom="5dp"
            android:textColor="#000000"
            android:paddingTop="5dp">
        </android.support.v4.view.PagerTabStrip>

    </android.support.v4.view.ViewPager>

</LinearLayout>

I have looked on the internet for answers but haven't come across anything that will insert a vertical scrollbar inside a viewPager that the view inside is created dynamically/programitcally and without xml

Crosswalk 14 - orientation is not changing

In my app build on crosswalk 14 and ionic there is no orientation change. if You rotate device - no change. My congif.xml file

App crashes on orientation change after I change my listview in same activity

My app starts in the MainActivity and uses a loader and custom adapter to populate my listview with the users' favourites. The data will persist over the orientation change.

But then if the user performs a search the listview in the MainActivity is repopulated with the new data. That works fine. But now, an orientation change crashes my app.

I'm also confused whether I have to explicitly save my instance before an orientation change or if Android does it for me. And if I have to do it explicitly would it be better to just perform the database query again instead?

I have seen a few other questions but they are either old or unanswered.

Add event to Week view library

I'm using this library : http://ift.tt/1rtrYBv And I want that when I click on an empty space, an event will show up on the calendar, but it doesnt..The event is added to events variable. but you cant see it in the calendar
here is my code:

      List<WeekViewEvent> events = new ArrayList<WeekViewEvent>();

   mWeekView.setEmptyViewClickListener(new WeekView.EmptyViewClickListener() {
            @Override
            public void onEmptyViewClicked(Calendar calendar) {

                Calendar cal2 = (Calendar) calendar.clone();
                cal2.add(Calendar.HOUR, 1);
                WeekViewEvent event = new WeekViewEvent(1,"Hello", calendar, cal2);
                event.setColor(getActivity().getResources().getColor(R.color.event_color_01));
                events.add(event);

                events.add(event);
                onMonthChange(2015,5);
            }
        });

 @Override
    public List<WeekViewEvent> onMonthChange(int newYear, int newMonth) {
    return events;
}

Getting back object from child activiy in Android

I have a main_activity that starts a child Activity via Intent.

I know about methods getStringExtra(string), or getBooleanExtra(string) etc. that we call in onActivityResult; But they all return a primitive data... How can I get an object from a user-defined class from the child activity?

Thanks, and this is my first question here! :) kinda too late...

Proper use cases for Android ActivityManager.isUserAMonkey()?

I was looking at the new APIs introduced in Android 2.2. While looking at the ActivityManager class I came across the following method:

public static boolean isUserAMonkey()

Used to determine whether the user making this call is subject to teleportations.

Returns whether the user making this call is a monkey.

How and when should this be used?

Saving state of `EditText` visibility

I have couple of editTexts that are set to VISIBLE and INVISIBLE by a button click. I tried saving the state of visibility or invisibility using a Boolean and setting it to True when it became VISIBLE and setting it to False when it was INVISIBLE. I don't know why but it didn't save the state. Can someone show me an example or steer me the right way to save the state of the editText's visibility. I'm an android newbie, any help would be appreciated, thanks.

public void Visible() { ////this button click will make the editext visible, if it is invisible
if(e1.getVisibility() == View.INVISIBLE){
    e1.setVisibility(View.VISIBLE);
} else if(e2.getVisibility() == View.INVISIBLE){
    e2.setVisibility(View.VISIBLE);
 }
 }
 public void invisible(){ //this button click will make the editext invisible, if it is visible
if(e2.getVisibility() == View.VISIBLE)
{
    e2.setVisibility(View.INVISIBLE);
}
else if(e1.getVisibility() == View.VISIBLE){
    e1.setVisibility(View.INVISIBLE);
}
 }

Am I doing the right thing? or not? When i click the button of the drawing of path the application stopped. I don't know how i will get get the lat and long of the inputted destination to autocomplete textview and the user location. I just only need to draw path from the current location of the user and from the location that inputted by the user.

Canvas and android button

so maybe my problem will be so obvious but I've tried many trials and any of them were succesfull. So I'm writing simple program to generate fractal on canvas. But I need to add some button on this same layer and I have a problem because I can only add them on RelativeLayout and there are being hidden by canvas. How to solve it? If nedd I can paste my code.

DrawView.java

package com.example.rafa.fractalsgenerator;

import android.content.Context;
import android.graphics.Canvas;
import android.graphics.Color;
import android.graphics.Paint;
import android.view.View;

public class DrawView extends View {

protected Paint paint = new Paint();

public DrawView(Context context) {
    super(context);
}

@Override
public void onDraw(Canvas canvas) {}  //this public method will be changed       in other class
 }

The next one:

MainActivity.java

package com.example.rafa.fractalsgenerator;

import android.app.Activity;
import android.graphics.Color;
import android.support.v7.app.ActionBarActivity;
import android.os.Bundle;
import android.view.Menu;
import android.view.MenuItem;
import android.view.View;
import android.widget.Button;
import android.widget.FrameLayout;


public class MainActivity extends Activity implements View.OnClickListener {

BarnsleyFern fern;
Button button;

@Override
public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);

    fern = new BarnsleyFern(this);
    fern.setBackgroundColor(Color.WHITE);
    button = (Button) findViewById(R.id.button);

    setContentView(fern);

  }

  @Override
  public void onClick(View v) {
  }
 }

The last java file:

BarnsleyFern.java

package com.example.rafa.fractalsgenerator;

import android.content.Context;
import android.graphics.Canvas;
import android.graphics.Color;

public class BarnsleyFern extends DrawView {

private double x,y,newx,newy; //coordinates of point of iteration
private double xe,ye; //screen coordinates
private  double rand; //generated number from [0;1) to choose corect  iteration equation
private final int Nmax = 180000; //number of iteration

public BarnsleyFern(Context context) {
    super(context);
}

@Override
public void onDraw(Canvas canvas) {

    paint.setColor(Color.argb(127, 255, 0, 255));

    x =0;
    y= 0;  //beginning values

    for (int i = 0; i < Nmax; i++) {

        rand = Math.random();

        if (rand < 0.01) {
            x = 0;
            y = 0.16 * y;
        }
        else if (rand < 0.84) {
            newx = (0.85 * x) + (0.04 * y);
            newy = (-0.04 * x) + (0.85 * y) + 1.6;
            x = newx;
            y = newy;
        }
        else if (rand < 0.92) {
            newx = (0.2 * x) - (0.26 * y);
            newy = (0.23 * x) + (0.22 * y) + 1.6;
            x = newx;
            y = newy;
        }
        else {
            newx = (-0.15 * x) + (0.28 * y);
            newy = (0.26 * x) + (0.24 * y) + 0.44;
            x = newx;
            y = newy;
        }
        xe = (float) (70*x + 300);
        ye = (float) (70*y +55);
        canvas.drawCircle((float) xe, (float) ye,1,paint); //cast needed cause, drawCircle(float,x float y...)
    }

   }

  }

And the xml file:

<RelativeLayout
android:id="@+id/mainView"
xmlns:android="http://ift.tt/nIICcg"
xmlns:tools="http://ift.tt/LrGmb4"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:orientation="vertical">

    <Button
        android:id="@+id/button"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:text="Color" />
  </RelativeLayout>

                        }

                        @Override
                        public void onProgressUpdate(String imageUri,

                        }
                    });


return vi;
}

This is Key WIdth and Height Image from URL

String var_news_article_image_width = news_article_image
                    .get(Variabel.KEY_NEWSARTICLEIMAGEWIDTH);
            String var_news_article_image_height = news_article_image
                    .get(Variabel.KEY_NEWSARTICLEIMAGEHEIGHT);

.. so how to this work ?

Android ListView doesnot refresh by Filter

In my application I have three fragment with ViewPager. one of this fragments i have simple Arraylist as ListView from phones contact list and i'm trying to filter that after typing into edittext. but doesn't refresh until softkeyboard is visible and I must have to hide keyboard to refresh list view by filtered strings.

For example:

filter listview by "a":

adapter.getFilter().filter("a");

My adapter implements from Filterable

public class AdapterContacts extends BaseAdapter implements Filterable {

softkeyboard status status in Manifest for ActivityMain. this class have view pager with three fragment:

    <activity android:name=".Activities.ActivityBootstrap" android:windowSoftInputMode="adjustPan"  android:screenOrientation="portrait"/>

Fragment is not shown on Activity

In my App,One Activity has to include three fragments, one of them always remains on Activity but the other two have to change places. But fragments are not shown on an activity.

I have read somewhere here that I should change LinearLayout to FragmentLayout but it did not work.

public class MainActivity extends ActionBarActivity {

private final Fragment_1to6 f1to6 = new Fragment_1to6();
private final Fragment_7to12 f7to12 = new Fragment_7to12();

private FragmentManager mFragmentManager;
private FrameLayout mButtonsLayout, mLayout1to6;
private FrameLayout mLayout7to12;

private static final int MATCH_PARENT = LinearLayout.LayoutParams.MATCH_PARENT;
private static final int WRAP_CONTENT = LinearLayout.LayoutParams.WRAP_CONTENT;

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);


    mButtonsLayout = (FrameLayout) findViewById(R.id.fragment_buttons);
    mLayout1to6 = (FrameLayout) findViewById(R.id.fragment_1to6);
    mLayout7to12 = (FrameLayout) findViewById(R.id.fragment_7to12);

    mFragmentManager = getFragmentManager();
    final FragmentTransaction ft = mFragmentManager.beginTransaction();

    ft.add(R.id.fragment_buttons, new buttonsFragment());
    ft.add(R.id.fragment_1to6, f1to6);

    ft.addToBackStack("fragment_buttons");
    ft.addToBackStack("fragment_1to6");

    ft.commit();

    mFragmentManager
            .addOnBackStackChangedListener(new FragmentManager.OnBackStackChangedListener() {
                public void onBackStackChanged() {
                    setLayout();
                }
            });


    mFragmentManager.executePendingTransactions();


}

private void setLayout() {

    // Determine whether the Fragment has been added
    if (!f7to12.isAdded()) {

        mButtonsLayout.setLayoutParams(new LinearLayout.LayoutParams(WRAP_CONTENT,
                MATCH_PARENT, 1f));
        mLayout1to6.setLayoutParams(new LinearLayout.LayoutParams(WRAP_CONTENT,
                MATCH_PARENT, 6f));
    } else {

        mButtonsLayout.setLayoutParams(new LinearLayout.LayoutParams(WRAP_CONTENT,
                MATCH_PARENT, 1f));
        // Make the TitleLayout take 6/13 of the layout's width
        mLayout1to6.setLayoutParams(new LinearLayout.LayoutParams(WRAP_CONTENT,
                MATCH_PARENT, 6f));

        // Make the QuoteLayout take 6/13's of the layout's width
        mLayout7to12.setLayoutParams(new LinearLayout.LayoutParams(WRAP_CONTENT,
                MATCH_PARENT, 6f));
    }


}

how can i solve that ?

The correct way to create and write to an owned external SD card directory on Android 4.4 KitKat and up?

I have spent literally hours now looking for (and trying) many different ways to write some files to my 4.4 Android KitKat's external SD card. Now that Google has limited access to the filesystem on SD cards it seems you are forced to only be able to write to directories owned by the application (eg: /Android/data/com.mycompany.myapp/files/).

Finally I was able to get something working that creates a directory on the external SD card that can be written to. However I am curious why in order to create this owned directory on the external SD I first had to create a new file using a path to the internally owned directory?

first I create two globals to house the strings of both the internal and external paths.

MainActivity

public class MainActivity extends ActionBarActivity {
    String internalStorageDirectory;
    String externalStorageDirectory;

Then I ask the system where the directories are and start building absolute paths for both the internal and external variables followed by creating a new file for internalStorage.

onCreate()

internalStorageDirectory = this.getExternalFilesDir(null).toString();
File folderInt = new File(internalStorageDirectory); //THIS LINE IS CRUCIAL!!
Log.d("DEBUG", " - Internal Path" + internalStorageDirectory);// "/storage/emulated/0/Android/data/com.mycompany.httpreq2/files"


String ownedDirectory = "/Android/data/" + this.getPackageName();
externalStorageDirectory = System.getenv("SECONDARY_STORAGE").toString() + ownedDirectory + "/files//";
Log.d("DEBUG", " - External Path"+externalStorageDirectory);// "/storage/external/Android/data/com.mycompany.httpreq2/files//"

Finally I am able to save a file that I downloaded earlier from an AsyncTask.

doInBackground()

output = new FileOutputStream(externalStorageDirectory + "myawesomefile.mp4");

Then I was able to navigate to the SD card directory via adb shell and I could see my file.

adb shell output:

shell@QTAQZ3:/storage/external/Android/data/com.mycompany.myapp/files $ ls
ls
myawesomefile.mp4

So I guess my question is, why do I need to create a file for internal storage first:

File folderInt = new File(internalStorageDirectory); //THIS LINE IS CRUCIAL!!

before I can write to the external directory? Am I even doing this correctly?

Thanks for any insight into this, Cheers!
