将按钮对准屏幕右下方？

Question

I have a submit button here on the right of "Action" Button:

I've tried to use the code:

android:gravity="bottom|right"

but it doesn't work, and it still stays on the same place.

My full code is this:

<Button
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:gravity="bottom"
    android:keepScreenOn="true"
    android:textSize="25dp"
    android:padding="30dp"
    android:textStyle="bold"
    android:textAlignment="center"
    android:text="@string/select_action"
    android:id="@+id/btnSelectPhoto"
    android:layout_alignParentBottom="true"/>

<Button
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:layout_toRightOf="@id/btnSelectPhoto"
    android:keepScreenOn="true"
    android:gravity="bottom|right"
    android:padding="30dp"
    android:text="@string/submit"
    android:textSize="25dp"
    android:textStyle="bold"
    android:id="@+id/btnSubmit"
    android:layout_alignParentBottom="true"
    />

Even with the code above, the layout is still the same as the image. How can I fix this?

Fixed: Added android:layout_alignParentRight="true", Thanks to Egor N.

Answer 1

android:layout_alignParentRight="true" should do the job. But, you should get rid of android:layout_toRightOf="@id/btnSelectPhoto" .

android:gravity didn't work, because this value is applied to content inside the view (text inside a button).

Answer 2

You can use a simlpe View between the two bottons

for example:

<LinearLayout
    android:orientation="horizontal"
    android:weightSum="3"
    android:layout_width="match_parent"
    android:layout_height="80dp"
>
    <Button
        android:layout_width="0dp"
        android:layout_height="match_parent"
        android:layout_weight="1"/>

    <View
        android:layout_width="0dp"
        android:layout_height="match_parent"
        android:layout_weight="1"/>

    <Button
        android:layout_width="0dp"
        android:layout_height="match_parent"
        android:layout_weight="1"/>
</LinearLayout>
