Answer 1

Instead of using android:src in the imageView xml use android:background then just recieve it at the source java file then use the following code:

ImageView img=(ImageView)findViewById(R.id.image);
img.setBackgroundDrawable(getResource().getDrawable(R.drawable.lamp_on));

Hope this will work for you.

Use this make this xml in your drawble folder, you can add more images to it in the same way. they will all apear on top of each other.

<?xml version="1.0" encoding="utf-8"?>
<layer-list xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent">
<item>
    <bitmap android:src="@drawable/img1"
        android:gravity="center"
        />
</item>
<item>
    <bitmap android:src="@drawable/img2"
        android:gravity="center"
        />
</item>
</layer-list>

In layout add one more ImageView and align Top, Bottom, Right, Left to first one. Make it invisible;

<FrameLayout android:id="@+id/my_ph"    
xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="wrap_content"
android:layout_height="wrap_content">
<ImageView  
    android:id="@+id/image"
    android:layout_width="wrap_content" 
    android:layout_height="wrap_content" 
    android:src="@drawable/sketch" android:layout_alignParentTop="true"/>
<ImageView  
    android:id="@+id/image2"
    android:layout_width="fill_parent" 
    android:layout_height="fill_paren" 
    android:layout_alignTop="@id/image"
    android:layout_alignLeft="@id/image"
    android:layout_alignRight="@id/image"
    android:layout_alignBottomp="@id/image"
    android:visibility="INVISIBLE"/>
</FrameLayout>

Then in code:

ImageView image2 =(ImageView)findViewById(R.id.image2);
image2.setVisibility(View.VISIBLE);
image2.setImageResource(R.drawable.my_image);

Answer 4

and the answer....

 RelativeLayout rv = (RelativeLayout) findViewById(R.id.my_ph);
 RelativeLayout.LayoutParams params;
 ImageButton im1 = new ImageButton(this);

 im1.setBackgroundResource(R.drawable.lamp);
 im1.setId(i);
 im1.setOnClickListener(new OnClickListener() {
     public void onClick(View v) {
        TextView tx = (TextView) findViewById(R.id.textView1);
        tx.setText("lamp #" + v.getId());
     }
 });

 params = new RelativeLayout.LayoutParams(40, 40);
 params.leftMargin = x;
 params.topMargin = y;
 rv.addView(im1, params);

XML Layout:

 <RelativeLayout 
            android:id="@+id/my_ph"
            xmlns:android="http://schemas.android.com/apk/res/android"
            android:layout_width="wrap_content" 
            android:layout_height="wrap_content" 
            android:gravity="bottom">
    <ImageView 
            android:id="@+id/image" 
            android:layout_width="wrap_content"
            android:layout_height="wrap_content" 
            android:layout_alignParentTop="true"
            android:background="@drawable/map" />
    <TextView 
            android:id="@+id/textView1" 
            android:layout_width="wrap_content"  
            android:layout_height="wrap_content"
            android:textAppearance="?android:attr/textAppearanceLarge"
            android:layout_below="@+id/image" 
            android:layout_alignParentLeft="true">
    </TextView>

 </RelativeLayout>
