Android - Come dividere una vista in 4 parti uguali?

Question

Mi piacerebbe prendere uno schermo, dividerlo in quattro quadrati di colori diversi e allegare un click listener a loro.

La mia domanda è: come posso dividere lo schermo su 4 quadrati uguali.

Grazie in anticipo!

Ecco un layout con 4 pulsanti con diversi colori:

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

<LinearLayout 
    android:layout_width="match_parent" 
    android:layout_height="match_parent" 
    android:layout_weight="1.0" 

    android:orientation="horizontal" > 

    <Button 
     android:id="@+id/button1" 
     android:layout_width="match_parent" 
     android:layout_height="match_parent" 
     android:background="@android:color/white" 
     android:layout_weight="1.0" 
     android:text="Button" /> 

    <Button 
     android:id="@+id/button2" 
     android:layout_width="match_parent" 
     android:layout_height="match_parent" 
     android:background="@android:color/holo_green_light" 
     android:layout_weight="1.0" 
     android:text="Button" /> 

</LinearLayout> 

<LinearLayout 
    android:layout_width="match_parent" 
    android:layout_height="match_parent" 
    android:layout_weight="1.0" 
    android:orientation="horizontal" > 

    <Button 
     android:id="@+id/button3" 
     android:layout_width="match_parent" 
     android:layout_height="match_parent" 
     android:background="@android:color/holo_blue_light" 
     android:layout_weight="1.0" 
     android:text="Button" /> 

    <Button 
     android:id="@+id/button4" 
     android:layout_width="match_parent" 
     android:layout_height="match_parent" 
     android:background="@android:color/holo_red_light" 
     android:layout_weight="1.0" 
     android:text="Button" /> 

</LinearLayout> 
</LinearLayout>

Il codice seguente dividerà lo schermo in quattro parti.

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

<LinearLayout 
    xmlns:android="http://schemas.android.com/apk/res/android" 
    android:layout_width="match_parent" 
    android:layout_height="0dp" 
    android:layout_weight="1" 
    android:orientation="horizontal" > 

    <LinearLayout 
     xmlns:android="http://schemas.android.com/apk/res/android" 
     android:layout_width="0dp" 
     android:layout_height="match_parent" 
     android:layout_weight="1" 
     android:orientation="horizontal" > 
    </LinearLayout> 

    <LinearLayout 
     xmlns:android="http://schemas.android.com/apk/res/android" 
     android:layout_width="0dp" 
     android:layout_height="match_parent" 
     android:layout_weight="1" 
     android:orientation="horizontal" > 
    </LinearLayout> 
</LinearLayout> 


<LinearLayout 
    xmlns:android="http://schemas.android.com/apk/res/android" 
    android:layout_width="match_parent" 
    android:layout_height="0dp" 
    android:layout_weight="1" 
    android:orientation="horizontal" > 

    <LinearLayout 
     xmlns:android="http://schemas.android.com/apk/res/android" 
     android:layout_width="0dp" 
     android:layout_height="match_parent" 
     android:layout_weight="1" 
     android:orientation="horizontal" > 
    </LinearLayout> 

    <LinearLayout 
     xmlns:android="http://schemas.android.com/apk/res/android" 
     android:layout_width="0dp" 
     android:layout_height="match_parent" 
     android:layout_weight="1" 
     android:orientation="horizontal" > 
    </LinearLayout> 
</LinearLayout> 

Utilizzare qualsiasi "vista" invece "LinearLayout", ma con l'uso suoi attributi in questo.
