Android Drawable question

I am trying to create a drawable in code and change the color based on some criteria. I can get it to work but it doesn't want to let me set the padding on the view. Any help would be appreciated.

<?xml version="1.0" encoding="utf-8"?>

<ImageView
    android:id="@+id/icon"
    android:layout_width="50px"
    android:layout_height="fill_parent"
/>

<TextView
    android:id="@+id/label"
    android:layout_width="wrap_content"
    android:layout_height="wrap_cont开发者_如何学Cent"
    android:paddingLeft="17px"
    android:textSize="28sp"
/>

            ImageView icon = (ImageView) row.findViewById(R.id.icon);
        ShapeDrawable mDrawable;

        int x = 0;
        int y = 0;
        int width = 50;
        int height = 50;

        float[] outerR = new float[] { 12, 12, 12, 12, 12, 12, 12, 12 };

        mDrawable = new ShapeDrawable(new RoundRectShape(outerR, null, null));
        mDrawable.setBounds(x, y+height, x + width, y);



        switch(position){

        case 0:
            mDrawable.getPaint().setColor(0xffff0000);      //Red
            break;
        case 1:
            mDrawable.getPaint().setColor(0xffff0000);      //Red
            break;
        case 2:
            mDrawable.getPaint().setColor(0xff00c000);      //Green
            break;
        case 3:
            mDrawable.getPaint().setColor(0xff00c000);      //Green
            break;
        case 4:
            mDrawable.getPaint().setColor(0xff0000ff);      //Blue
            break;
        case 5:
            mDrawable.getPaint().setColor(0xff0000ff);      //Blue
            break;
        case 6:
            mDrawable.getPaint().setColor(0xff696969);      //Gray
            break;
        case 7:
            mDrawable.getPaint().setColor(0xff696969);      //Gray
            break;
        case 8:
            mDrawable.getPaint().setColor(0xffffff00);      //Yellow
            break;
        case 9:
            mDrawable.getPaint().setColor(0xff8b4513);      //Brown
            break;
        case 10:
            mDrawable.getPaint().setColor(0xff8b4513);      //Brown
            break;
        case 11:
            mDrawable.getPaint().setColor(0xff8b4513);      //Brown
            break;
        case 12:
            mDrawable.getPaint().setColor(0xffa020f0);      //Purple
            break;
        case 13:
            mDrawable.getPaint().setColor(0xffff0000);      //Red
            break;
        case 14:
            mDrawable.getPaint().setColor(0xffffd700);      //Gold
            break;
        case 15:
            mDrawable.getPaint().setColor(0xffff6600);      //Orange
            break;
        }

        icon.setBackgroundDrawable(mDrawable);
        icon.setPadding(5, 5, 5, 5);

If I set the padding in XML it just ignores it.

Thanks, Rob

Try setting padding for the ShapeDrawable(link).

And one more thing is, padding will move the image view contents not the background ( i.e image view itself). You are setting the drawable as ImageView background.

Use setImageDrawable() function to get the image view setPadding() effect.
