Hi all
In my map application I couldn't drag&drop the MapView when Zoom
Controller is displayed. But I found SDK's maps application can do it.
Would you like to let me know how to implement it in my code? Thank
you very much.

i know another method..
you can use the onTouchEvent method to get the amount of drag and then use scrollby to scroll the map..
regards

I got it.

Syntax: [ Download ] [ Hide ]

Using java Syntax Highlighting

    
// The Zoom Controls will be displayed on bottom center.
 
    void showZoomControls()
 
    {
 
        // Please use relativelayout in googlemaps.xml, otherwise zoom controller can't be gotten displayed.
 
        LinearLayout zoomLayout = (LinearLayout) findViewById(R.id.map_zoom);
 
        zoomLayout.addView(mMapView.getZoomControls(),
 
                        new ViewGroup.LayoutParams(LayoutParams.WRAP_CONTENT,
 
                        LayoutParams.WRAP_CONTENT));
 
        // Please do not use following codes to display zoom controller;
 
        // otherwise, drag & drop will be gotten no response when the zoom 
 
        // controller is displayed.
 
        // Zoom View 
 
        //LinearLayout zoomView = (LinearLayout) mMapView.getZoomControls(); 
 
        //zoomView.setLayoutParams( new ViewGroup.LayoutParams(LayoutParams.WRAP_CONTENT, 
 
        //              LayoutParams.WRAP_CONTENT )); 
 
        //zoomView.setGravity(Gravity.BOTTOM + Gravity.CENTER_HORIZONTAL); 
 
        //mMapView.addView(zoomView); 
 
        //mMapView.displayZoomControls(true);
