ListView inside ScrollView II

See only one item

You do not have to do anything special in layout.xml file nor handle anything on the parent ScrollView. You only have to handle the child ListView. You can also use this code to use any type of child view inside a ScrollView & perform Touch operations.

ScrollView inside ListView

Just add these lines of code in your java class :

listView.setOnTouchListener(new ListView.OnTouchListener() {
            @Override
            public boolean onTouch(View v, MotionEvent event) {
                // Disallow the touch request for parent scroll on touch of child view
                v.getParent().requestDisallowInterceptTouchEvent(true);
                return false;
            }
        });

        super(context);
    }
    public NonScrollListView(Context context, AttributeSet attrs) {

    public NonScrollListView(Context context, AttributeSet attrs, int defStyle) {
        super(context, attrs, defStyle);

    public void onMeasure(int widthMeasureSpec, int heightMeasureSpec) {
        int heightMeasureSpec_custom = View.MeasureSpec.makeMeasureSpec(
                Integer.MAX_VALUE >> 2, View.MeasureSpec.AT_MOST);
        super.onMeasure(widthMeasureSpec, heightMeasureSpec_custom);
        ViewGroup.LayoutParams params = getLayoutParams();
        params.height = getMeasuredHeight();
    }
}

In Your Layout File

<?xml version="1.0" encoding="utf-8"?>

    android:scrollbars="none" >

    <RelativeLayout
        android:layout_width="match_parent"

        <!-- com.Example Changed with your Package name -->

        <com.thedeveloperworldisyours.view.NonScrollListView
            android:id="@+id/lv_nonscroll_list"

            <!-- Your another layout in scroll view -->

        </RelativeLayout>
    </RelativeLayout>

</ScrollView>

In Java File

Create a object of your customListview instead of ListView like :

NonScrollListView non_scroll_list = (NonScrollListView) findViewById(R.id.lv_nonscroll_list);

Infinitely Scrolling List

When you use a List or Grid, sometimes common requirement is to dynamically load more data as the user keeps scrolling down making it a potentially infinite scrolling list. This blog will guide you on how to implement this feature in your app.

Infinitely Scrolling List

We will need is our InfiniteScrollListener class that will implement OnScrollListener. Let’s jump right in and see the code for this class.

public abstract class InfiniteScrollListener implements AbsListView.OnScrollListener {
    private int mBufferItemCount = 10;
    private int mCurrentPage = 0;
    private int mItemCount = 0;
    private boolean mIsLoading = true;

    public InfiniteScrollListener(int bufferItemCount) {
        this.mBufferItemCount = bufferItemCount;
    }

    public abstract void loadMore(int page, int totalItemsCount);

    @Override
    public void onScrollStateChanged(AbsListView view, int scrollState) {
        // Do Nothing
    }

    @Override
    public void onScroll(AbsListView view, int firstVisibleItem, int visibleItemCount, int totalItemCount) {
        if (totalItemCount < mItemCount) {
            this.mItemCount = totalItemCount;
            if (totalItemCount == 0) {
                this.mIsLoading = true;
            }
        }

        if (mIsLoading && (totalItemCount > mItemCount)) {
            mIsLoading = false;
            mItemCount = totalItemCount;
            mCurrentPage++;
        }

        if (!mIsLoading && (totalItemCount - visibleItemCount) <= (firstVisibleItem + mBufferItemCount)) {
            loadMore(mCurrentPage + 1, totalItemCount);
            mIsLoading = true;
        }
    }

}

Then in our onCreate of Activity We must put this:

mGridView.setOnScrollListener(new InfiniteScrollListener(5) {
            @Override
            public void loadMore(int page, int totalItemsCount) {
                mProgressDialog.show();
                // your code
            }
        });

Video MediaPlayer

We can stream media, including video, to a MediaPlayer object using a surface view.

Video MediaPlayer

For example, you could use the following layout:

<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:tools="http://schemas.android.com/tools"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:background="#000000"
    android:paddingBottom="@dimen/activity_vertical_margin"
    android:paddingLeft="@dimen/activity_horizontal_margin"
    android:paddingRight="@dimen/activity_horizontal_margin"
    android:paddingTop="@dimen/activity_vertical_margin"
    tools:context=".MainActivity" >

    <SurfaceView
        android:id="@+id/activity_video_surfView"
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        android:layout_above="@+id/activity_video_imageButton_play"/>

    <Button
        android:id="@+id/activity_video_imageButton_play"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_alignParentBottom="true"
        android:layout_centerHorizontal="true"
        android:background="@android:drawable/ic_media_play" />

</RelativeLayout>

We will refer to the SurfaceView in the implementation of the Activity class.

Now in our Activity class, add the following interfaces:

public class VideoActivity extends Activity implements SurfaceHolder.Callback{

Your IDE should prompt you to add these unimplemented methods:

@Override
public void surfaceChanged(SurfaceHolder arg0, int arg1, int arg2, int arg3) {
    // TODO Auto-generated method stub
}

@Override
public void surfaceCreated(SurfaceHolder arg0) {
//setup
}

@Override
public void surfaceDestroyed(SurfaceHolder arg0) {
    // TODO Auto-generated method stub
}

@Override
public void onPrepared(MediaPlayer mp) {
//start playback
}

In surfaceCreated we must add these code line:

try {
	mMediaPlayer = new MediaPlayer();
	mMediaPlayer.setDisplay(mVidHolder);
	mMediaPlayer.setDataSource(Constants.VID_ADDRESS);
	mMediaPlayer.prepare();
	mMediaPlayer.setOnPreparedListener(this);
	mMediaPlayer.setAudioStreamType(AudioManager.STREAM_MUSIC);
} catch (Exception e) {
	e.printStackTrace();
}

In surfaceDestroyed we add this:

mMediaPlayer.stop();

MediaPlayer Audio

There are different ways to control audio. MediaPlayer is good way. We see how to use MediaPlayer for control audio.

Download code

First step is to create file which name is raw in res/
Then in raw we must paste a song in mp3 format.
MediaPlayer Audio

In order to use MediaPlayer , we have to call a static Method create() of this class. This method returns an instance of MediaPlayer class. Its syntax is as follows:

MediaPlayer mMediaPlayer = MediaPlayer.create(this, R.raw.song);

The second parameter is the name of the song that you want to play. You have to make a new folder under your project with name raw and place the music file into it.

Once you have created the Mediaplayer object you can call some methods to start or stop the music. These methods are listed below.

mMediaPlayer.start();
mMediaPlayer.pause();

you can read more about this methods in this link

Now We see simple example, First we need this strings

<string name="app_name">MediaPlayer</string>
    <string name="now_play">Now Playing:</string>
    <string name="inital_time">0 min, 0 sec</string>
    <string name="pausing_sound">Pausing sound</string>
    <string name="playing_sound">Playing sound</string>
    <string name="action_song">Song</string>

In our activity_main.xml we need couple of textViews and imageButtons.
