I tried a couple things and nothing is working... I'm trying to change the BackgroundColor on a ImageView on Android, but nothing happens...

Here is my xml:

<ImageView
   android:id="@+id/imageView1"
   android:layout_width="350dp"
   android:layout_height="550dp"
   android:layout_above="@+id/btnInfo"
   android:layout_alignLeft="@+id/fundo"
   android:layout_alignRight="@+id/btnInfo"
   android:layout_alignTop="@+id/fundo"
   android:layout_centerHorizontal="true"
   android:contentDescription="@string/backgroundMain" />

And the code:

public void onStart()
    {
        super.onStart();
        Log.d("Teste", "In the onStart() event 5");

        ImageView backgroundImg = (ImageView) findViewById(R.id.imageView1);
        backgroundImg.setBackgroundColor(Color.rgb(255, 255, 255));
    }

What am I missing?

RGB:255, 255, 255 is the color code for WHITE. Since your parent layout background color is also white you won't see the difference.

Try changing color like

backgroundImg.setBackgroundColor(Color.rgb(100, 100, 50));

Or else change the background color of parent layout.
