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

Question

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"<\/code> and alignParentRight="true"<\/code> , but with Framelayout I did not find any such attributes. How do I align it to the bottom-right of screen?

Answer 1

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.

Answer 3

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>

Answer 4

设置android:layout_gravity="bottom|right"对我android:layout_gravity="bottom|right"

Answer 5

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" 

Answer 6

android:layout_gravity="bottom"

Answer 7

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

Answer 8

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>

Answer 9

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

Answer 10

使用bottom|right<\/code>作为您希望在父布局的右下位置对齐的元素的layout_gravity<\/code>值。

android:layout_gravity="bottom|right"

Answer 11

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?
