Android: How to get id of ImageView without using onclick() event

Here's my XML :

    <ImageView android:id="@+id/IVtarih1"
               android:layout_height="125dp" 
               android:layout_width="125dp" />

And my Activity

    ImageView image1 = (ImageView) findViewById(R.id.IV1);
    new DownloadImageTask(image1).execute(urlStr1);
    ImageView iv = (ImageView) findViewById(R.id.IV2)

    iv.setImageResource(R.id.image1);//I can't find id of image1

I'm getting the background of image1 from an url. So i don't have any drawable. I want to set background of image1 to ImageView iv. How can I do this? I thought that if I find the id of image1 I can achive this. The id of image1 is changing every runtime.

You seem to be confused. You don't need the ImageView's id for that. You just need to do imgView.setImageResource(R.drawable.drawable_name).

Set the id in the XML ahead of time like

<ImageView 
        android:id="@+id/myImageView"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"/>

Then in your Activity you can get it by

ImageView myImage = (ImageView)findViewById(R.id.myImageView);
