Android "Hello World" Layout Problem on Galaxy Tab Screen

Hi guys :)

I'm trying to run a simple "Hello World" program with a button and a textview. This is the layout:

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout android:id="@+id/layout"
              xmlns:android="http://schemas.android.com/apk/res/android"
              android:layout_w开发者_如何学Cidth="match_parent"
              android:layout_height="match_parent"
              android:orientation="vertical" >
    <TextView android:id="@+id/text"
              android:layout_width="wrap_content"
              android:layout_height="wrap_content"
              android:text="text"
              android:layout_gravity="center_horizontal" />
    <Button android:id="@+id/button"
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:text="button"
            android:layout_gravity="center_horizontal" />
</LinearLayout>

The problem is that it doesn't look good on the simulator with Samsung Galaxy Tab's resolution. The view doesn't take all available space as I wish but only a portion. Is "match_parent" correct in layout's width and height?

SOLUTION: add <uses-sdk android:minSdkVersion="4" /> in the manifest.xml

      xmlns:android="http://schemas.android.com/apk/res/android"
      android:layout_width="fill_parent"
      android:layout_height="fill_parent"
      android:orientation="vertical" >

try this... it may work.

I think there should be fill_parent
