Android: Add Dynamic Image from server to ViewSwitcher

In your main.xml layout file, you'll want something like the followng

    android:layout_width="fill_parent"
    android:layout_height="fill_parent"
    android:orientation="vertical" >

            android:id="@+id/vfShow"
        android:layout_width="fill_parent"
        android:layout_height="fill_parent" >
       
       
   

  -------------------------------------------------------------------------------------------------------------

  In your example_Layout.xml layout file, you'll want something like the followng

  xmlns:android="http://schemas.android.com/apk/res/android"
  android:orientation="vertical"
  android:layout_width="match_parent"
  android:layout_height="match_parent">

In code image download from the server and display dynamically in view switcher

In your code then where this layout file is referenced, you can initialize your Views as follows...

 public class deal extends Activity {
      private static final int SWIPE_MIN_DISTANCE = 120;
      private static final int SWIPE_THRESHOLD_VELOCITY = 200;
 

//http://www.example.com/abc/

     String imageUrl="http://www.example.com/abc/";
     String[] im={"img1.png","img2.png","img3.png","img4.png","img5.png"};
     private ImageView imageLoader;
     private ProgressDialog bar;
     private final int ONE = 0;
     private ImageView img;
      private ViewFlipper vf;
      private Context mContext;
      private final GestureDetector detector = new GestureDetector(
            new MyGestureDetector());

    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.main);
        mContext = this;
        //new ImageDownload().execute(im[1]);
        vf = (ViewFlipper) this.findViewById(R.id.vfShow);
        vf.setOnTouchListener(new OnTouchListener() {
            @Override
            public boolean onTouch(final View view, final MotionEvent event) {
                detector.onTouchEvent(event);
                return true;
            }
        });
        Bundle extras = getIntent().getExtras(); 
      
        String a = extras.getString("deal");
        for(int i=0;i<4 br="" i="">        {
           img = new ImageView(getApplicationContext());
          //AsyncImageLoaderv asyncImageLoaderTop = new AsyncImageLoaderv();
        //   img.setImageBitmap(new DownloadImagesTask().execute(imageUrl + im[i]));
         // ImageView ima =(ImageView)findViewById(R.id.imageView1);
         //TextView t= (TextView)findViewById(R.id.textView1);
        //  t.setText("Deals No - " );
         
             Bitmap bitmap = DownloadImage(imageUrl + im[i]);
           
              img.setImageBitmap(bitmap);
