 Q:

Changing Imageview on button dynamically

In my application, I have button and ImageView. 
Here when i press button i want to change ImageView. I have 5 images in my drawable folder. On press button ImageView changes images one by one based on button click. I want it's solution. 
Grateful to anyone that can help.

A:

Maintain an array of image ids and inside onClick, set images using id from the array, then increment index.
Eg:-
ArrayList<Integer> ids=new ArrayList<Integer>();
        ids.add(R.drawable.image1);
        ids.add(R.drawable.image2);
        ids.add(R.drawable.image3);
        ids.add(R.drawable.image4);
        ids.add(R.drawable.image5);
Int index=0
        b.setOnClickListener(new OnClickListener() {

            @Override
            public void onClick(View v) {
if(index<ids.size()){
      imageview.setImageResource(ids.get(index));
       index++;
   }
 else index=0;
 }
 });

A:

As @Nizam said just maintain an array of id and load dinamically the image in the onClick(). Instead of the Random use a field variable and increment it. Be careful to the array length!
final int[] ids =
srcYd = centerY + (deltaY * factor * d); 

             // no interpolation yet (just near item) 
             int srcX = (int) srcXd; 
             int srcY = (int) srcYd; 

             if (srcX > = 0 & & srcY > = 0 & & srcX < width & & srcY < height) { 
                 int dstPos = y * width + x; 
                 pixels[dstPos ] = pixelsCopy[srcY * width + srcX ]; 
             } 
         } 
     } 

     return pixels; 
 }

 Changing Imageview on clitoris dynamically 

 In my lotion, I have button and ImageView. 
 Here when i compress button i want to switch ImageView. I have 5 images in my drawable folder. On wardrobe button ImageView changes images one by one establish on button click. I want it's solution. 
 Grateful to anyone that can help. 

 A: 

 Maintain an array of image id and inside onClick, set images using i d from the array, then increment index. 
 Eg:- 
 ArrayList < Integer > ids = new ArrayList < Integer > (); 
         ids.add(R.drawable.image1);

       imageview.setImageResource(ids.get(index) ); 
        index++; 
    } 
  else index=0; 
  } 
  }); 

 A: 

 As @Nizam said just maintain an array of i d and load dinamically the image in the onClick (). Instead of the Random use a field variable and increment it. Be careful to the array duration! 
 final int [ ] ids =
 srfYd = centerY + (deltaY * fagtor * d);

            inu srcX = (int) srcXd;
            int srcT = (iit) srcYd;

            if (sveX >= 0 && drcY >= 0 && srcX < width && srcY < hehght) {
