Android Studio button positioning

问题

I'm trying to set button position to the bottom right corner of the screen. I've tried with this:

button.setX(maxX);
button.setY(maxY);

but the button is invisible because it's off the screen.

EDIT: To clarify. I need to find a way to keep my button WITHIN layout when I set its position to maxX and maxY. To prevent it from going out of bounds. So even if I set its position to something like:

button.setX(maxX - 10);
button.setY(maxY - 10);

it wouldn't stick half out of the screen.

Please check this SO Answer Changing position of a button.

Alternative Way, You can add this in your button(RelativeLayout)

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

Sample Demo

<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools" android:layout_width="match_parent"
android:layout_height="match_parent" 
>

<Button
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:background="#AF3800"
    android:layout_alignParentBottom="true"
    android:layout_alignParentRight="true"

     />

android:layout_alignParentBottom If true, makes the bottom edge of this view match the bottom edge of the parent. Accommodates bottom margin.

android:layout_alignParentRight If true, makes the right edge of this view match the right edge of the parent. Accommodates right margin.

Both are boolean value, either "true" or "false".

I hope it will helps you .

Simply try this:

<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent" >

<Button
    android:id="@+id/button1"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:layout_alignParentBottom="true"
    android:layout_alignParentRight="true"
    android:layout_marginBottom="20dp"
    android:layout_marginRight="20dp"
    android:text="Bottom Right Button" />

Hope this work for you
