Google マップ アプリで問題が発生しています。今のところ、アプリは自分の位置をズームインするためのサポートのみでしたが、機能していません。私の場所の離れた場所は、マップの上部で終わります。これが私のコードです: MainActivity:
public class MainActivity extends Activity implements LocationListener {
private GoogleMap googleMap;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
if (isGooglePlayOk()) {
setContentView(R.layout.activity_main);
setMap();
googleMap.setMyLocationEnabled(true);
}
}
@Override
public boolean onCreateOptionsMenu(Menu menu) {
// Inflate the menu; this adds items to the action bar if it is present.
getMenuInflater().inflate(R.menu.main, menu);
return true;
}
@Override
public boolean onOptionsItemSelected(MenuItem item) {
// TODO Auto-generated method stub
switch (item.getItemId()) {
case R.id.action_legalnotices:
startActivity(new Intent(this, LegalNoticeActivity.class));
return true;
default:
return false;
}
}
private boolean isGooglePlayOk() {
int status = GooglePlayServicesUtil.isGooglePlayServicesAvailable(this);
if (status == ConnectionResult.SUCCESS) {
return (true);
}
else {
((Dialog) GooglePlayServicesUtil.getErrorDialog(status, this, 10))
.show();
}
return (false);
}
@TargetApi(Build.VERSION_CODES.HONEYCOMB)
private void setMap() {
if (googleMap == null) {
googleMap = ((MapFragment) getFragmentManager().findFragmentById(
R.main.map)).getMap();
if (googleMap != null) {
}
googleMap.setMyLocationEnabled(true);
LocationManager la = (LocationManager) getSystemService(LOCATION_SERVICE);
String provider = la.getBestProvider(new Criteria(), true);
Location loc = la.getLastKnownLocation(provider);
if (provider != null) {
onLocationChanged(loc);
}
googleMap.setOnMapLongClickListener(onLongClickMapSettiins());
}
}
private OnMapLongClickListener onLongClickMapSettiins() {
// TODO Auto-generated method stub
return new OnMapLongClickListener() {
@Override
public void onMapLongClick(LatLng point) {
Toast.makeText(getApplicationContext(), "OK",
Toast.LENGTH_SHORT).show();
}
};
}
@Override
public void onLocationChanged(Location location) {
LatLng latlong = new LatLng(location.getLatitude(),
location.getLongitude());
googleMap.setMyLocationEnabled(true);
CameraPosition cp = new CameraPosition.Builder().target(latlong)
.zoom(15).build();
googleMap.moveCamera(CameraUpdateFactory.newCameraPosition(cp));
}
@Override
public void onProviderDisabled(String provider) {
// TODO Auto-generated method stub
}
@Override
public void onProviderEnabled(String provider) {
// TODO Auto-generated method stub
}
@Override
public void onStatusChanged(String provider, int status, Bundle extras) {
// TODO Auto-generated method stub
}
}

自分のデバイスでしかテストできません。マップは正常に機能していますが、mylocationbutton をクリックしただけではすぐに画面の中央に自分の位置を取得できません。誰かが私を助けることができますか？
