here is the xml layout file

and here is the main.xml layout file

<TextView android:id="@+id/TextView01" android:layout_width="wrap_content"
    android:layout_height="wrap_content" android:text="This is my sample App of android"
    android:textColor="#000000" android:textSize="20dip">

<EditText android:id="@+id/EditText01" android:layout_height="wrap_content"
    android:layout_width="fill_parent"></EditText>

<Button android:id="@+id/Button01" android:layout_width="wrap_content"
    android:layout_height="wrap_content" android:text="Say Hello"></Button>

Answer 1

Check android:windowSoftInputMode attribute for activity element of AndroidManifest.xml. In your case it could be:

<activity android:windowSoftInputMode="stateAlwaysVisible" ... />

Answer 2

<activity android:windowSoftInputMode="stateAlwaysVisible" ... />

as Ralkie's answer. But to test on emulator you have to be careful in how your AVD is configured: the default configuration has keyboard support... You need to add the hardware property "Keyboard support" with "no" value on your AVD in order to test it on emulator.
