Apps Focus: MapView(RelativL.) and EditText(LinearL.)

puk · Feb 27, 2009

hello, i'm writing an application wich uses the map with a search-field on top of the map. the main.xml looks like that:

Code:

<LinearLayout>

 <LinearLayout-x>
  <EditText (search-String) />
  <Button (send-Button) />
 </LinearLayout-x>

 <RelativLayout-y>
  <MapView />
  <LinearLayout (zoomelements) />
 </RelativLayout-y>

</LinearLayout>

If using the d-pad(up down left right) the two fields (LinearLayout-x and RelativeLayout-y) react both at the same time to the input. That means if scrolling through the text in the Edit Field the map changes the zoom. Because I'm using the d-pad for managing the map. Do i need focus-stuff or does anyone has a better idea for controlling my application?
I tried to play a little bit with the focus options of android, without success

main.xml

Code:

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" 
    android:id="@+id/main" 
    android:orientation="vertical" 
    android:layout_width="fill_parent" 
    android:layout_height="fill_parent"> 
    
    <LinearLayout android:orientation="horizontal" 
        android:layout_width="fill_parent" 
        android:layout_height="wrap_content" >
        
        <EditText android:id="@+id/field_search" 
            android:layout_width="fill_parent" 
            android:layout_height="wrap_content" 
            android:layout_weight="1"
              android:scrollbars="vertical" 
              android:lines="1" />
        <Button android:id="@+id/search" 
            android:text="search"
            android:layout_width="wrap_content"
            android:layout_height="fill_parent" />
    </LinearLayout>
    
    <RelativeLayout android:orientation="vertical"
        android:layout_width="fill_parent"
        android:layout_height="fill_parent"
        android:layout_weight="1" 
        android:focusable="true" 
        android:focusableInTouchMode="true">

        <com.google.android.maps.MapView
            android:id="@+id/map" 
            android:layout_width="fill_parent" 
            android:layout_height="fill_parent" 
            android:enabled="true" 
            android:clickable="true" 
            android:apiKey="0CMIRxnrxbszEq1rT5ApxgzjYGcwtStf-4Vagfg" />
        
        <LinearLayout
            android:id="@+id/zoomelements"
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:layout_alignBottom="@id/map"
            android:layout_centerHorizontal="true"
        />
    </RelativeLayout>

         itemizedoverlay.addOverlay(overlitem);
         mapOverlays.add(itemizedoverlay);
    }

    @Override  
    public boolean dispatchKeyEvent(KeyEvent event) {  
        if(event.getKeyCode() == KeyEvent.KEYCODE_DPAD_UP) {  
            zoomValue = zoomValue + 1;  
            mc.setZoom(zoomValue);  
        } else if(event.getKeyCode() == KeyEvent.KEYCODE_DPAD_DOWN) {  
            zoomValue = zoomValue - 1;  
            mc.setZoom(zoomValue);  
        } else if(event.getKeyCode() == KeyEvent.KEYCODE_DPAD_LEFT) {  
            map.setSatellite(false);  
        } else if(event.getKeyCode() == KeyEvent.KEYCODE_DPAD_RIGHT) {  
            map.setSatellite(true);  
        }  
        return super.dispatchKeyEvent(event);  
    }
    
    @Override
    protected boolean isRouteDisplayed() {
        // TODO Auto-generated method stub
        return false;
    }
}

My code is based on the android tutorial:
