Android ImageView is not bring to front

Question

android ImageView is not bringing to front in RelativeLayout

Tried to call bringtofront() didn't work tried setting visibility to true didn't work

XML CODE

           <?xml version="1.0" encoding="utf-8"?>
        <!-- This file is /res/layout/main.xml -->
         <LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
         android:id="@+id/spellingLevel1Layout"
         android:layout_width="fill_parent"
         android:layout_height="fill_parent"
         android:orientation="horizontal" >

<RelativeLayout
    android:id="@+id/canvas_container"
    android:layout_width="fill_parent"
    android:layout_height="fill_parent"
    android:background="@drawable/magnetboard" >

       <ImageView
            android:id="@+id/imageView1"
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:layout_marginLeft="480dp"
            android:layout_marginTop="600dp"
            android:adjustViewBounds="true" />

     </RelativeLayout>

   </LinearLayout>

Java Code

   public class spellingLevel1 extends Activity {         
   rel1 = (RelativeLayout) findViewById(R.id.canvas_container);
   mImageView1 = (ImageView) findViewById(R.id.imageView1);
   image1();

}
  public void randomNumber() {
      Random rando = new Random();
      currentLetter = myImageList[rando.nextInt(myImageList.length)];
  }
  public void image1(){
      //randomNumber();

      mImageView1 = (ImageView) findViewById(R.id.imageView1);
      mImageView1.setBackgroundResource(R.drawable.spelling_);        
      mImageView1.bringToFront();
      mImageView1.requestLayout();




  }

UPDATED CODE

   rel1 = (RelativeLayout) findViewById(R.id.canvas_container);
   mImageView1 = (ImageView) findViewById(R.id.imageView1);
   image1();

}
  public void randomNumber() {
      Random rando = new Random();
      currentLetter = myImageList[rando.nextInt(myImageList.length)];
  }
  public void image1(){
      //randomNumber();

      mImageView1 = (ImageView) findViewById(R.id.imageView1);
      mImageView1.setImageResource(R.drawable.spelling_); //updated here to setImageResource          
      mImageView1.bringToFront();

Still does not show

its not the full code but it should be everything to help you see what is included in here

It would be nice to know what else is in the layout - such as if you have a SurfaceView or a VideoView - something that does not conform to standard z-orders. — Phil, Apr 30 '13 at 15:00
I updated it theres really nothing in here, just a standard relative view — baron dune, Apr 30 '13 at 15:12
You shouldn't need to call `bringToFront()` or `requestLayout()`. What happens if you remove those lines? — Phil, Apr 30 '13 at 15:21
i think the problem is not with the order of the views. try to change the background of the image to white and set it's size to 50*50 to see if it's visible. i think the problem is with your resource or the location of the image (maybe the screen is smaller than 480*600?) — Rotem, May 02 '13 at 13:10
decreasing the margins worked, but question, will this margin it out for every device or am I only setting these margins for my device? — baron dune, May 02 '13 at 13:17

You should define the image source of the ImageView. because it's size is set to wrap_content and it has no content, the size stays 0.

This seems a little misleading. The width attribute stays at `wrap_content` - so once content is added (aka the image source), the width will no longer be zero. Lookup `LayoutParams` for a better understanding. – Phil Apr 30 '13 at 15:23
That's right, but he never set the content so it stays on 0 :). – Rotem Apr 30 '13 at 15:36
He should change the setBackgroundImage to setImageResource – Rotem Apr 30 '13 at 15:38
I have an array of images that's why it's set background image. How would I convert the image resource to accept an array form – baron dune Apr 30 '13 at 17:00
the same way you do this now, just change the setBackgroundImage to setImageResource. I'm not sure I understand the problem – Rotem Apr 30 '13 at 17:05
I think I may be confused because I am a novice. Basically when I try calling imageresource it gives me an error – baron dune Apr 30 '13 at 22:27
now what happens is the imageview is not bringing to the front of the drawable relative background – baron dune May 02 '13 at 13:02
