        android:layout_width="fill_parent"
        android:layout_height="0dp"
        android:layout_gravity="left"
        android:layout_weight="33"
        android:background="#336699"
         android:padding="10dp"
        android:scaleType="fitStart"
        android:src="@drawable/balancemoney_logo" />

    <ImageButton
        android:id="@+id/imageButton1"
        android:layout_width="fill_parent"
        android:layout_height="0dp"
        android:layout_gravity="right"
        android:layout_weight="33"
        android:background="#336699"
         android:padding="10dp"
        android:scaleType="center"
        android:src="@drawable/balancemoney_logo" />

    <ImageButton
        android:id="@+id/imageButton1"
        android:layout_width="fill_parent"
        android:layout_height="0dp"
        android:layout_gravity="right"
        android:layout_weight="33"
        android:background="#336699"
        android:padding="10dp"
         android:scaleType="fitEnd"
        android:src="@drawable/balancemoney_logo" />

</LinearLayout>

it shows 3 buttons.Anyway if i change the LinearLayout to RelativeLayout it doesn't show me any button.It just show the balnk screen.what is wrong with RelativeLayout ?

[Ulf Dittmer]

Nothing is wrong with RelativeLayout, but there is probably something wrong with how you're using it. But we can't speculate on what that might be because you didn't post the layout.

[shawn peter]

this is the main class we are using

package com.example.twotext;

import android.app.Activity;
import android.os.Bundle;

public class Test extends Activity {

	
	@Override
	public void onCreate(Bundle savedInstanceState) {
		super.onCreate(savedInstanceState);
		try{
		setContentView(R.layout.main_button);
		}catch(Exception e){
			e.printStackTrace();
		}
	}
	
}

first xml that i posted is the layout file.

[Ulf Dittmer]

That's the LinearLayout that you said works. Post the RelativeLayout that you said didn't work.

[shawn peter]

the same layout ,only change to the relativelayout.

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

    <ImageButton
        android:id="@+id/imageButton1"
        android:layout_width="fill_parent"
        android:layout_height="0dp"
       
        android:layout_weight="33"
        android:background="#336699"
         android:padding="10dp"
        android:layout_alignParentTop="true"
        android:layout_alignParentLeft="true"
        android:src="@drawable/balancemoney_logo" />

    <ImageButton
        android:id="@+id/imageButton2"
        android:layout_width="fill_parent"
        android:layout_height="0dp"
        
        android:layout_weight="33"
        android:background="#336699"
         android:padding="10dp"
        android:layout_alignBottom="@+id/imageButton1"
        android:layout_centerHorizontal="true"
        android:src="@drawable/balancemoney_logo" />

    <ImageButton
        android:id="@+id/imageButton3"
        android:layout_width="fill_parent"
        android:layout_height="0dp"
       
        android:layout_weight="33"
        android:background="#336699"
        android:padding="10dp"
         android:layout_alignBottom="@+id/imageButton2"
         android:layout_alignParentRight="true"
        android:src="@drawable/balancemoney_logo" />

</RelativeLayout>

I see, you assumed RelativeLayout worked just the same as LinearLayout. That's not the case, though. Start reading here: http://developer.android.com/guide/topics/ui/layout/relative.html
