puting one imageView in front of the other in Android

Question

i have couple of imageViews that i create programmatically, so here is my question, if i want to put one imageView on the other, how can i tell my app which imageView is going to be on top, and which one on the bottom ? This is how i create ImageViews, and that works fine.

        image = new ImageView(this);

    RelativeLayout.LayoutParams params = new RelativeLayout.LayoutParams(
            RelativeLayout.LayoutParams.WRAP_CONTENT,
            RelativeLayout.LayoutParams.WRAP_CONTENT);

    image.setScaleType(ImageView.ScaleType.MATRIX);
    image.setImageResource(R.drawable.ic_launcher);
    image.setId(1);
         params.setMargins(0, 0, 0, 0);
     Let's get the root layout and add our ImageView

    ((ViewGroup) mainLayout).addView(image, params);

So this is what helped me in the end, i am gonna put it so it may be of use to someone else.

You can use this: http://developer.android.com/reference/android/view/View.html#bringToFront%28%29

Just use it like this

YourImageView.bringToFront();

After you created both of the images and you need to put one on top. This works for most Views.

If you want to draw ImageViews on top of each other then you should use a FrameLayout. This is a layout that draws views like a stack, the first child will be drawn first and others will be drawn on top of the previous. For example:

<FrameLayout
 android:layout_width="match_parent"
 android:layout_height="match_parent">
    <ImageView1 ... />
    <ImageView2 ... />
</FrameLayout>

If your layout is like this, and ImageView1 and ImageView2 overlap, then ImageView2 will be drawn over ImageView1 because it is the second child and is drawn last.

but i create my imageViews from code, not layout, thats why i can't do it with FrameLyout – Mate Križanac Oct 14 '13 at 22:28
is that possible? i didn't know i can use FrameLayout in code. Sorry, i am still a beginner. But i found a way to do this easy via code. I am gonna put my answer below. – Mate Križanac Oct 15 '13 at 12:21
@MateKrižanac A FrameLayout is simply a subclass of ViewGroup, so of course you can. :) Check out this link under the heading "Define a FrameLayout Programmatically": http://mobile.tutsplus.com/tutorials/android/android-sdk_frame-layout/ – telkins Oct 15 '13 at 13:52
