问题描述
我只是希望有一个图形页面来识别点击,为了调用另一个活动。
到现在为止,我试图正规的onClick,总是在常规视图为我工作,然后用一个onClickListener压倒一切的onTouchEvent以及最后但并非最不重要的。
我所有三种方式为以下code。任何帮助是非常AP preciated。
进口com.google.android.maps.MapActivity;
进口com.google.android.maps.MapView;
进口android.os.Bundle;
进口android.view.MotionEvent;
进口android.view.View;
公共类HelloMapView扩展MapActivity {
/ **第一次创建活动时调用。 * /
@覆盖
公共无效的onCreate(包savedInstanceState){
最后MapView的地图;
super.onCreate(savedInstanceState);
的setContentView(R.layout.main);
地图=(图形页面)findViewById(R.id.mapview);
map.setOnClickListener(新MapView.OnClickListener(){
公共无效的onClick(视图v){
的System.out.println(我听!);
}
});
}
@覆盖
保护的布尔isRouteDisplayed(){
返回false;
}
@覆盖
公共布尔的onTouchEvent(MotionEvent为arg0){
的System.out.println(的onTouchEvent事!);
super.onTouchEvent(为arg0);
返回super.onTouchEvent(为arg0);
}
公共无效的onClick(){
的System.out.println(的onClick进入!);
}
}
添加一个<一个href="http://$c$c.google.com/intl/el-GR/android/add-ons/google-apis/reference/com/google/android/maps/Overlay.html"相对=nofollow>覆盖在地图中查看和处理的onTouchEvent。尝试是这样的:
公共类MyMapActivity扩展MapActivity {
类MapOverlay扩展com.google.android.maps.Overlay
{
@覆盖
公共布尔的onTouchEvent(MotionEvent E,图形页面图形页面)
{
如果(e.getAction()== MotionEvent.ACTION_UP){
的GeoPoint P = MapView.getProjection()在。fromPixels(
(int)的e.getX(),
(int)的e.getY());
MyMapActivity this.startActivityForResult(意向,要求code);
}
返回false;
}
}
// MyMapActivity方法
@覆盖
公共无效的onCreate(包savedInstanceState){
super.onCreate(savedInstanceState);
图形页面=(图形页面)findViewById(R.id.mapview);
MapOverlay mapOverlay =新MapOverlay();
名单&LT;覆盖&GT; listOfOverlays =调用MapView.getOverlays();
listOfOverlays.clear();
listOfOverlays.add(mapOverlay);
}
}
I simply want a mapview to recognize a click, in order to call another activity.
Until now, i tried the regular "onClick",that always worked for me in regular Views, followed by overriding "onTouchEvent" and last but not least using an onClickListener.
I out all three ways into the following code. Any help is highly appreciated.
import com.google.android.maps.MapActivity;
import com.google.android.maps.MapView;
import android.os.Bundle;
import android.view.MotionEvent;
import android.view.View;
public class HelloMapView extends MapActivity {
/** Called when the activity is first created. */
@Override
public void onCreate(Bundle savedInstanceState) {
final MapView map;
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
map = (MapView) findViewById(R.id.mapview);
map.setOnClickListener(new MapView.OnClickListener() {
public void onClick(View v){
System.out.println("I listened!");
}
});
}
@Override
protected boolean isRouteDisplayed() {
return false;
}
@Override
public boolean onTouchEvent(MotionEvent arg0) {
System.out.println("onTouchEvent happened!");
super.onTouchEvent(arg0);
return super.onTouchEvent(arg0);
}
public void onClick(){
System.out.println("onClick entered!");
}
}
Add an Overlay in your map view and handle the OnTouchEvent. Try something like this:
public class MyMapActivity extends MapActivity {
class MapOverlay extends com.google.android.maps.Overlay
{
@Override
public boolean onTouchEvent(MotionEvent e, MapView mapView)
{
if (e.getAction() == MotionEvent.ACTION_UP) {
GeoPoint p = mapView.getProjection().fromPixels(
(int) e.getX(),
(int) e.getY());
MyMapActivity this.startActivityForResult(intent, requestCode);
}
return false;
}
}
// MyMapActivity methods
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
mapView = (MapView) findViewById(R.id.mapview);
MapOverlay mapOverlay = new MapOverlay();
List<Overlay> listOfOverlays = mapView.getOverlays();
listOfOverlays.clear();
listOfOverlays.add(mapOverlay);
}
}
