Add FrameLayout At The bottom Of Any Activity Programmatically

How can I find the root view of an activity, then add a framelayout at the bottom? On the contrary, code below add to the top, but can't to its bottom. 

    FrameLayout aLayout = new FrameLayout(getActivity());
    aLayout.setLayoutParams(new LayoutParams(LayoutParams.FILL_PARENT, LayoutParams.WRAP_CONTENT));

    ImageView image = new ImageView(getActivity());
    image.setLayoutParams(new LayoutParams(LayoutParams.FILL_PARENT, LayoutParams.WRAP_CONTENT));
    image.setImageResource(R.drawable.alayer_0);
    adLayout.addView(image);

    ViewGroup content = (ViewGroup) getActivity().findViewById(android.R.id.content);
    content.addView(aLayout);

android.R.id.content is a FrameLayout. So you cannot align child view to bottom.

What you can do is add a RelativeLayout to android.R.id.content with FILL_PARENT for height and width.

You can now add your FrameLayout to the RelativeLayout with ALIGN_PARENT_BOTTOM.

Alternatively you can also add a margin around your FrameLayout. No need for an additional RelativeLayout.

DisplayMetrics metrics = MyActivity.this.getResources().getDisplayMetrics();
LayoutParams params = new LayoutParams(LayoutParams.WRAP_CONTENT, LayoutParams.WRAP_CONTENT);
params.setMargins(0, metrics.heightPixels - 20, 0, 0);
myFrameLayout.setLayoutParams(params);

This will position the FrameLayout 20 pixels from the bottom of the screen.

Assign some id to your Root layout(Main layout of your XML)

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:id="@+id/linear_root"
    android:orientation="vertical"
    android:layout_width="fill_parent"
    android:layout_height="fill_parent">

Activity class, Map the Root layout

LinearLayout mRootLayout;

mRootLayout=(LinearLayout) findViewById(R.id.linear_root);

mRootLayout.add(yourFrameLayout);// this will add your FrameLayout at the last

Update: To get the Root Layout of any Activity then you can use getRootView

or getWindow().getDecorView().findViewById(android.R.id.content)

looks like you want to add a footer. Start your xml with framelayout and then include your footer in a linear or relative layout and give android:layout_gravity="bottom". This will solve your problem.

Might be one solution is that you should use by xml ,in xml first take one relative layout and than inside that relative layout take your frame layout and set property of frame layout as-

android:layout_alignParentBottom="true"

so your frame layout will be shown on the bottom of screen.Hope it will work perfectly for you.
