我目前正在开发一个跟踪某个设备的Android应用程序，其中一个按钮（即button2）负责启动MapsActivity。我将MapsActivity复制到另一个应用程序中，在该应用程序中它是唯一的活动，并且它工作正常，但是当我尝试使用按钮（button2）访问它时，它在其他应用程序中崩溃。

MainActivity java代码片段（实现了所有需要的导入）：

package com.example.finalprototype;

 public class MainActivity extends ActionBarActivity {
 private ProgressDialog progressDialog;
 Button button1;
 Button button3;
 Button button2;


@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);


    button1 = (Button) findViewById(R.id.button1);
    button1.setOnClickListener(new OnClickListener() {

        @Override
        public void onClick(View arg0) {
            // TODO Auto-generated method stub
            new LoadTracker().execute();

        }
    });
    button2 = (Button)findViewById(R.id.button2);
    button2.setOnClickListener(new OnClickListener() {
        @Override
        public void onClick(View v) {

            startActivity(new Intent(MainActivity.this, MapsActivity.class));
            finish();
        }
    });




    button3 = (Button)findViewById(R.id.button3);
    button3.setOnClickListener(new OnClickListener() {
        @Override
        public void onClick(View v) {
            startActivity(new Intent(MainActivity.this, MainActivity2Activity.class));
            finish();

        }
    });
}

MapsActivity Code（实现了所有需要的导入）：

        package com.example.finalprototype;


 public class MapsActivity extends ActionBarActivity
  implements OnMapClickListener, OnMapLongClickListener,  OnMarkerClickListener{

final int RQS_GooglePlayServices = 1;
private GoogleMap myMap;
static final int POLYGON_POINTS=4;
ArrayList<LatLng> markers = new ArrayList<>();

Location myLocation;
TextView tvLocInfo;

boolean markerClicked;
PolygonOptions polygonOptions;
Polygon polygon;
Button setgeo;


@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_maps);

    setgeo =(Button)findViewById(R.id.setgeo);

    setgeo.setOnClickListener(new View.OnClickListener() {
        public void onClick(View v) {
            // Perform action on click
            String Point1 = markers.get(0).toString();
            String Point2 = markers.get(2).toString();

        }
    });





    tvLocInfo = (TextView)findViewById(R.id.locinfo);

    FragmentManager myFragmentManager = getFragmentManager();
    MapFragment myMapFragment = (MapFragment)myFragmentManager.findFragmentById(R.id.map);
    myMap = myMapFragment.getMap();

    myMap.setMyLocationEnabled(true);

    myMap.setMapType(GoogleMap.MAP_TYPE_HYBRID);

    myMap.setOnMapClickListener(this);
    myMap.setOnMapLongClickListener(this);
    myMap.setOnMarkerClickListener(this);

    markerClicked = false;
}






@Override
protected void onResume() {

    super.onResume();

    int resultCode = GooglePlayServicesUtil.isGooglePlayServicesAvailable(getApplicationContext());

    if (resultCode == ConnectionResult.SUCCESS){
        Toast.makeText(getApplicationContext(),
                "isGooglePlayServicesAvailable SUCCESS",
                Toast.LENGTH_LONG).show();
    }else{
        GooglePlayServicesUtil.getErrorDialog(resultCode, this, RQS_GooglePlayServices);
    }

}

@Override
public void onMapClick(LatLng point) {
    tvLocInfo.setText(point.toString());
    myMap.animateCamera(CameraUpdateFactory.newLatLng(point));

    markerClicked = false;
}

@Override
public void onMapLongClick(LatLng point) {
    tvLocInfo.setText("New marker added@" + point.toString());
    myMap.addMarker(new MarkerOptions().position(point).title(point.toString()));
    markers.add(point);

    markerClicked = false;
}


@Override
public boolean onMarkerClick(Marker marker) {

    if(markerClicked){

        if(polygon != null){
            polygon.remove();
            polygon = null;
        }


        polygonOptions.add(marker.getPosition());
        polygonOptions.strokeColor(Color.BLUE);
        polygonOptions.fillColor(0x3300FF);
        polygonOptions.strokeWidth(3);
        polygon = myMap.addPolygon(polygonOptions);



    }else{
        if(polygon != null){
            polygon.remove();
            polygon = null;
        }

        polygonOptions = new PolygonOptions().add(marker.getPosition());
        markerClicked = true;
    }

    return true;
}
