Set the image dynamically in imageView in android

Question

I am a new in android programming. I want to set dynamically images in one xml, when this displayed. Specifically, i am storing my project related images in drawable folder. Also I am storing the image names in string variable and dynamically I am trying to set those images to the imageview. But the image is not displaying.

My code:

 protected void onCreate( Bundle savedInstanceState ) 
 {
 super.onCreate( savedInstanceState );
 setContentView( R.layout.stone ); 
 imageView = ( ImageView )findViewById( R.id.stone_xxxx );
 Intent intent = getIntent();
 position = intent.getStringExtra( "POSITION" );
 if ( position == "0" )
 {
 int imageResource = getResources().getIdentifier( "@drawable/stone_a1", null, getPackageName() );
 Drawable res = getResources().getDrawable(imageResource);
 imageView.setImageDrawable( res );
 }
 }

• RBK: can you log value of imageResource after int imageResource = getResources().getIdentifier( "@drawable/stone_a1", null, getPackageName() )

Answer 1

set in ImageView

iv.setImageResource(R.drawable.image)

Answer 2

Try this

final int sdk = android.os.Build.VERSION.SDK_INT;
if(sdk < android.os.Build.VERSION_CODES.JELLY_BEAN) {
 imageView.setBackgroundDrawable( getResources().getDrawable(R.drawable.stone_a1) );
} else {
 imageView.setBackground( getResources().getDrawable(R.drawable.stone_a1));
}

• Mohammad Tauqir: @Ezazel, Have you tried debugging it. I think problem lies in if ( position == "0" )
• Panagiotis: Yes you are right. It must be: if ( position.equals( "0" ) ) In addition i am using only: imageView.setImageResource( R.drawable.stone_a1 )

Hope it will work for you..

imagev1=(ImageView) findViewById(R.id.imageViewslider22);
 final int []imageArray={R.drawable.img1,R.drawable.img2,R.drawable.img3,R.drawable.img4,R.drawable.slider3,R.drawable.slider4,R.drawable.slider5,R.drawable.slider6,R.drawable.slider7};
 final Handler handler = new Handler();
 Runnable runnable = new Runnable() {
 int i=0;
 public void run() {
 imagev1.setImageResource(imageArray[i]);
 i++;
 if(i>imageArray.length-1)
 {
 i=0; 
 }
 handler.postDelayed(this, 30000); //for interval...
 }
 };
 handler.postDelayed(runnable, 2000); //for initial delay..

ImageView imageView = new ImageView(this);
