How can I disable all views inside the layout?

For example I have:

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:orientation="vertical"
    android:layout_width="fill_parent"
        android:layout_height="fill_parent">
     <Button 
        android:id="@+id/backbutton"
        android:text="Back"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content" />
    <LinearLayout
        android:id="@+id/my_layout"
        android:orientation="horizontal"
        android:layout_width="fill_parent"
        android:layout_height="wrap_content">
        <TextView
            android:id="@+id/my_text_view"
            android:text="First Name"
            android:layout_width="wrap_content"
            android:layout_height="wrap_content" />
        <EditText
            android:id="@+id/my_edit_view"
            android:width="100px"
            android:layout_width="wrap_content"
            android:layout_height="wrap_content" /> 
        <View .../>
        <View .../>
        ...
        <View .../>
    </LinearLayout>

</LinearLayout>

Is there a way to disable (setEnable(false)) all elements inside LinearLayout my_layout ?

Solution 1:

this one is recursive for ViewGroups

private void disableEnableControls(boolean enable, ViewGroup vg){
    for (int i = 0; i < vg.getChildCount(); i++){
       View child = vg.getChildAt(i);
       child.setEnabled(enable);
       if (child instanceof ViewGroup){ 
          disableEnableControls(enable, (ViewGroup)child);
       }
    }
}

Solution 2:

Another way is to call setEnabled() on each child (for example if you want to do some extra check on child before disabling)

LinearLayout layout = (LinearLayout) findViewById(R.id.my_layout);
for (int i = 0; i < layout.getChildCount(); i++) {
    View child = layout.getChildAt(i);
    child.setEnabled(false);
}
