Layout is not Displayed as shown in the Graphical layout?

Question

I have a Layout in my App Which has 5 Frame Layouts.I have Designed it in the Graphical Layout.It shows Perfect in the layout.But when I Run the App in the Device it is not showing the 2 green buttons with the Keyboard symbol.It Displays Only the Red Area in the App.

I Already Tested the Layout with another Activity.It works perfect.I think there is a Error in the below class.I can't find where it Happens ???

Nothing is shown in the LogCat...

So Help me in the Right Direction :)

Thanks for your Help ...

Answer 1

Atlast I Found why the Layout is not shown Properly in my App. It is Due to the this line in my three Initialization Methods .

 if(!Settings.hideMouseButtons) lp.height=0;

After Commenting this Line the layout shows properly.

Thanks for @chintan khetiya & @Robinhood who helped to Solve this.

Answer 2

Its Seems that your java file code is wrong. Your first function should be OnCreate() and rest of the code should be write after that.

Even you have set your view after long code which is totally wrong.

public class PadActivity extends Activity {
// set your variables & objects 
..
..

 @Override
 public void onCreate(Bundle savedInstanceState)
 {
 super.onCreate(savedInstanceState);
 setContentView(R.layout.pad_layout); 
 ...
 ... //Other code
 } 
}

Please change your code position that will definitely work.

Answer 3

@id/flTouchPad's height is match_parent, which I think is the problem (it makes the View as big as its parent).
