I have just started learning android. And i don't know How can I change the image of an ImageView? ie it has some Image which was set in the layout but i want to change that image through coding how should i do it ?

Here is the xml file

<LinearLayout
  xmlns:android="http://schemas.android.com/apk/res/android"
  android:layout_width="fill_parent"
  android:layout_height="fill_parent"
  android:background="#cc8181"
 >

<ImageView
  android:id="@+id/image"
  android:layout_width="50dip"
  android:layout_height="fill_parent" 
  android:src="@drawable/icon"
  android:layout_marginLeft="3dip"
  android:scaleType="center"/>

thanks for replying.

if (android.os.Build.VERSION.SDK_INT >= 21) {
            storeViewHolder.storeNameTextView.setImageDrawable(context.getResources().getDrawable(array[position], context.getTheme()));
} else {
            storeViewHolder.storeNameTextView.setImageDrawable(context.getResources().getDrawable(array[position]));
}

Have a look at the ImageView API. There are several setImage* methods. Which one to use depends on the image you provide. If you have the image as resource (e.g. file res/drawable/my_image.png)

ImageView img = new ImageView(this);  // or (ImageView) findViewById(R.id.myImageView);
img.setImageResource(R.drawable.my_image);

Just to go a little bit further in the matter, you can also set a bitmap directly, like this:

ImageView imageView = new ImageView(this);  
Bitmap bImage = BitmapFactory.decodeResource(this.getResources(), R.drawable.my_image);
imageView.setImageBitmap(bImage);

Of course, this technique is only useful if you need to change the image.
