I want to disable dispatch touch for some area for your understanding here is my screen.

enter image description here

You can see Header,Footer and Mapview in image but when I clicked on location button(right side in header), My map is also getting notified (like it got touched) which I don't want. I want that only onClick event of button should be clicked not dispatch event.

Here is my XML:

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:id="@+id/LinearLayout1"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:orientation="vertical" >

<!-- include title bar for all screen -->

<include
    android:id="@+id/include1"
    layout="@layout/titlebar_layout"
    android:layout_gravity="top" />



<FrameLayout
    android:layout_gravity="center"
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:layout_weight="0.88" 
    >

    <com.google.android.maps.MapView
        android:id="@+id/map"
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        android:layout_weight="1.63"
        android:apiKey="0VkXbAOFvAq7b6uaGHSmnS2a2VosPxoS6ceHY_g"
        android:clickable="true" >
    </com.google.android.maps.MapView>


</FrameLayout>

<include
    android:id="@+id/include2"
    android:layout_gravity="bottom"
    android:layout_marginBottom="38dp"
    layout="@layout/bottom_layout" />

</LinearLayout>

Any help will be greatly appreciated.

You can override the dispatchTouchEvent, and check where the user has touched the screen..

  @Override
public boolean dispatchTouchEvent(MotionEvent ev) {     
    //first check if the location button should handle the touch event
    if(locBtn != null) {
        int[] pos = new int[2];
        locBtn.getLocationOnScreen(pos);
        if(ev.getY() <= (pos[1] + locBtn.getHeight()) && ev.getX() > pos[0]) //location button event
            return locBtn.onTouchEvent(ev);
    }
        return super.dispatchTouchEvent(ev);
}
