Setimage from the source of an item

I have a code with lots of imageview and I would like to dynamically change them on a click. Do I really have to create a condition for every imageview clicked or can I do it simpler? As an example, is there a way to do something like:

@override
public void onClick(View view) {
    view.setImageBitmap(null)
}

In fact, I found a quite simple way to awnser my problem. first, I put all imageviews in an array and get the id of these in another array. Then I use Arrays.asList(array).indexOf(view.getId());

Pic[0] = (ImageView) findViewById(R.id.imageView1);
Pic[1] = (ImageView) findViewById(R.id.imageView2);
Pic[2] = (ImageView) findViewById(R.id.imageView3);
...

for (int i = 0; i < Pic.length; i++){
    id[i] = Pic[i].getId()
}
int u = Array.asList(id).indexOf(view.getId())
Pic[u].Setimagebitmap(null)

You can do this if you haven't yet, give onClick for all the images that you put

<ImageView
                android:id="@+id/image1"
                android:layout_width="wrap_content"
                android:layout_height="wrap_content"
                android:src="@drawable/image_1"
                android:onClick="onClick"
                android:layout_weight="1"

                android:layout_gravity="center_horizontal"
                />

Then in the activity you can make the Activity implement View.OnClickListener() and then define its onClick method as


@Override
    public void onClick(View view) {
        switch (view.getId()){
            case R.id.image1:
                 //Do your thing
                 break;
            case R.id.image2:
                 //Do your thing
                 break;
            //Add all cases like this
               }
          }

Let me know if this was helpful to you.
