Why is there a black bar at the bottom of my layout?_问答_开发者

I want to move the bottom bar in my layout all the way to the bottom of the screen, but there is a black bar at the bottom. How can I remove this black space so that my application fills the screen?

Here the code :

Why is there a black bar at the bottom of my layout?

Give android:height attribute of linear layout and table layout to fill_parent. It may work.

Put the <TableView> for the menu bar inside a <RelativeView android:layout_height="fill_parent" android:layout_width="fill_parent" android:gravity="bottom"> That should fix your problem. GL

try this :

<TableLayout
android:orientation="horizontal"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:gravity = "center_horizontal"
 android:layout_gravity="bottom"
android:stretchColumns="1,3,5,7">

Basically what you want to do is change the outermost layout to a relativelayout and have the bottom-most table layout thingie changed to android:layout_alignParentBottom="true"

try setting the android:layout_height attribute of the outermost LinearLayout to fill_parent
