Android: Align button to bottom-right of screen using FrameLayout?

I am trying to put the zoom controls of the map on the bottom right corner of screen. I could do it with RelativeLayout using both alignParentBottom="true" and alignParentRight="true", but with Framelayout I did not find any such attributes. How do I align it to the bottom-right of screen?

Actually it's possible, despite what's being said in other answers. If you have a FrameLayout, and want to position a child item to the bottom, you can use android:layout_gravity="bottom" and that is going to align that child to the bottom of the FrameLayout.

I know it works because I'm using it. I know is late, but it might come handy to others since this ranks in the top positions on google

I also ran into this situation and figured out how to do it using FrameLayout. The following output is produced by the code given below.

              <FrameLayout
                    android:layout_width="match_parent"
                    android:layout_height="wrap_content" >

                    <ImageView
                        android:layout_width="wrap_content"
                        android:layout_height="wrap_content"
                        android:src="@drawable/contactbook_icon"
                        android:layout_gravity="center" />
                    
                    <TextView
                        android:layout_width="wrap_content"
                        android:layout_height="wrap_content"
                        android:text="140"
                        android:textSize="12dp"
                        android:textColor="#FFFFFF"
                        android:layout_gravity="bottom|right"
                        android:layout_margin="15dp" />
                </FrameLayout>

Change the margin value to adjust the text position over the image. Removing margin might make the text to go out of the view sometimes.

It can be achieved using RelativeLayout

<RelativeLayout 
    android:layout_width="fill_parent"
    android:layout_height="fill_parent">

   <ImageView 
      android:src="@drawable/icon"
      android:layout_height="wrap_content"
      android:layout_width="wrap_content"
      android:layout_alignParentRight="true"
      android:layout_alignParentBottom="true" />

</RelativeLayout>

Setting android:layout_gravity="bottom|right" worked for me

Two ways to do this:

1. Using a Frame Layout

   android:layout_gravity="bottom|right"

2. Using a Relative Layout

   android:layout_alignParentRight="true" android:layout_alignParentBottom="true"

android:layout_gravity="bottom"

If you want to try with java code. Here you go -

    final LayoutParams params = new LayoutParams(LayoutParams.WRAP_CONTENT, 
                                             LayoutParams.WRAP_CONTENT);
    yourView.setLayoutParams(params);
    params.gravity = Gravity.BOTTOM; // set gravity

Use bottom|right as the layout_gravity value of the element which you wish to align in the bottom right position of the parent layout.

android:layout_gravity="bottom|right"

you can add an invisible TextView to the FrameLayout.

    <TextView
        android:layout_width="wrap_content"
        android:layout_height="0dp"
        android:layout_weight="1"
        android:visibility="invisible"
        />

    <LinearLayout
        android:layout_width="match_parent"
        android:layout_height="50dp"
        android:orientation="horizontal">
        <Button
            android:id="@+id/daily_delete_btn"
            android:layout_width="0dp"
            android:layout_height="50dp"
            android:layout_weight="1"
            android:text="DELETE"
            android:layout_gravity="center"/>
        <Button
            android:id="@+id/daily_save_btn"
            android:layout_width="0dp"
            android:layout_height="50dp"
            android:layout_weight="1"
            android:text="SAVE"
            android:layout_gravity="center"/>
    </LinearLayout>

There are many methods to do this using constraint widget of the activity.xml page of android studio.

Two most common methods are:

1. Select your button view and adjust it's margins.
2. Go to "All attributes",then to "layout_constraints",then select

• layout_constraintBottom_toBottomOf_parent
• layout_constraintRight_toRightOf_parent

You can't do it with FrameLayout.

From spec:

http://developer.android.com/reference/android/widget/FrameLayout.html

"FrameLayout is designed to block out an area on the screen to display a single item. You can add multiple children to a FrameLayout, but all children are pegged to the top left of the screen."

Why not to use RelativeLayout?
