我目前正在做一个项目,应用程序将获取用户的当前位置并将其显示在textview中的片段内。我没有得到任何错误,但由于某种原因,它不工作..Android使用LocationListener获取用户当前位置片段内
这是我的代码的一部分。 在清单和进口的所有权限都很好..
另一个奇怪的事情是我的应用程序不会显示我的logcat中的任何东西,当我点击按钮。
注:所有代码片段里面
希望有人可以给我一个提示或两个的感谢!
import android.content.pm.PackageManager;
import android.location.Location;
import android.location.LocationManager;
import android.location.LocationListener;
private LocationManager locationManager;
private LocationListener listener;
@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
// Inflate the layout for this fragment
View myinflate = inflater.inflate(R.layout.fragment_home, container, false);
final TextView cords = (TextView) myinflate.findViewById(R.id.welcome);
final Button butt = (Button) myinflate.findViewById(R.id.button1);
locationManager = (LocationManager) getActivity().getSystemService(getActivity().LOCATION_SERVICE);
listener = new LocationListener() {
@Override
public void onLocationChanged(Location location) {
cords.setText(location.getLatitude() +" "+location.getLongitude());
}
@Override
public void onStatusChanged(String provider, int status, Bundle extras) {
}
@Override
public void onProviderEnabled(String provider) {
}
@Override
public void onProviderDisabled(String provider) {
}
};
butt.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
if (ActivityCompat.checkSelfPermission(getActivity(), Manifest.permission.ACCESS_FINE_LOCATION) != PackageManager.PERMISSION_GRANTED && ActivityCompat.checkSelfPermission(getActivity(), Manifest.permission.ACCESS_COARSE_LOCATION) != PackageManager.PERMISSION_GRANTED) {
return;
}else {
locationManager.requestLocationUpdates(LocationManager.GPS_PROVIDER, 0, 0, listener);
}
}
});
return myinflate;
}

两个变量LocationSurface和AppConstants无法解析? – Duckbenok
LocationSurface&AppConstants是自定义的变量在我的应用程序 公共静态最终字符串[] PERMISSIONS_LOCATION = { Manifest.permission.ACCESS_FINE_LOCATION, Manifest.permission.ACCESS_COARSE_LOCATION }; public static final int REQUEST_CODE_PERMISSIONS = 2;请参考: https://developer.android.com/training/permissions/requesting.html – ahmedmsvb
