Question

I have an activity which is set up in the landscape mode and must remain this way(!So as an answer to my question don’t tell me to set my activity in the PORTRAIT mode cause this is not a solution).

And I wanna put a button at the bottom of the screen like this:

Here is my xml file:

<?xml version="1.0" encoding="utf-8"?>
<FrameLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:orientation="horizontal"
    android:layout_width="fill_parent"
    android:layout_height="fill_parent"
    android:gravity="center"
    >
<SurfaceView  
    android:layout_width="fill_parent" 
    android:layout_height="fill_parent" 
   android:id="@+id/surface_camera"
    />
<Button android:id="@+id/btnPhoto" 
android:layout_gravity="right" 
android:layout_width="wrap_content" 
android:layout_height="wrap_content" 
android:text="Take Photo !!"></Button>
</FrameLayout>

Don’t forget my activity is in LANDSCAPE mode.
Thank you!

The trick is done using layout_weight which is telling the layout to use all free space available. So you are creating two layouts the second with fixed height and the tell the first to use all the free space. This solution will work in both cases Landscape and Portrait mode.

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout android:layout_width="fill_parent"
android:layout_height="fill_parent" xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="vertical">
    <LinearLayout android:layout_width="fill_parent"
    android:layout_height="fill_parent" android:orientation="vertical"
    android:layout_weight="1.0">
    </LinearLayout>
    <LinearLayout android:layout_width="fill_parent"
    android:layout_height="40dp">
    <!-- place your buttons in this layout -->
    </LinearLayout>
</LinearLayout>

UPDATE

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout android:layout_width="fill_parent"
android:layout_height="fill_parent" xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="horizontal">
    <LinearLayout android:layout_width="fill_parent"
    android:layout_height="fill_parent" android:orientation="vertical"
    android:layout_weight="1.0">
    </LinearLayout>
    <LinearLayout android:layout_width="40dp"
    android:layout_height="fill_parent"></LinearLayout>
</LinearLayout>
