Ecco come ho creato un LinearLayout contenente tre LinearLayout, di cui uno esterno incluso, il tutto tramite manipolazione dell’xml.
activity_main.xml
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="horizontal"
tools:context="com.example.lab10.MainActivity" >
<LinearLayout
android:layout_width="0dp"
android:layout_height="match_parent"
android:layout_weight="1"
android:background="@drawable/w" >
</LinearLayout>
<include layout="@layout/hills"
android:layout_width="0dp"
android:layout_height="match_parent"
android:layout_weight="1" />
<LinearLayout
android:layout_width="0dp"
android:layout_height="match_parent"
android:layout_weight="1"
android:background="@drawable/w3" >
</LinearLayout>
</LinearLayout>
la parte marcata in giallo è l’inclusione dell’xml esterno.
hills.xml (xml esterno)
<?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:background="@drawable/hills"
android:orientation="vertical" >
</LinearLayout>
…e il risultato è perfetto!
