我为一些山路创建了一个谷歌地图应用程序;当我在模拟器上运行时，它运行得很好......（由于缺少GPS信号，它只是没有在地图上显示我当前的位置）。
但是当我在手机上安装它时（我在2台华为P8Lite手机上进行了测试）它的功能不一样：屏幕放大了，它没有显示我的位置，也没有放大/出按钮或当前位置按钮。此外，我实现的用于在toast消息中显示当前纬度和经度的按钮（如果启用了gps）仅显示空消息（它在模拟器上有效）...
这是.java文件：
package com.example.francydarkcool.maps;
public class MapsActivity extends AppCompatActivity implements OnMapReadyCallback {

String color;
Button mapbttn;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_maps);
SupportMapFragment mapFragment =
(SupportMapFragment) getSupportFragmentManager().findFragmentById(R.id.map);
mapFragment.getMapAsync(this);
mapbttn = (Button) findViewById(R.id.setRangeButton);
mapbttn.setOnClickListener(new View.OnClickListener() {
public void onClick(View v) {
btncoord();
}
});
// Bundle String color;
Bundle save = getIntent().getExtras();
if (save != null) {
color = save.getString("marker color");
}
}
public void btncoord() {
Toast.makeText(getApplicationContext(), "", Toast.LENGTH_LONG).show();
LocationManager locationManager = (LocationManager) getSystemService(Context.LOCATION_SERVICE);
// get the last know location from your location manager.
if (ActivityCompat.checkSelfPermission(this, android.Manifest.permission.ACCESS_FINE_LOCATION) != PackageManager.PERMISSION_GRANTED && ActivityCompat.checkSelfPermission(this, android.Manifest.permission.ACCESS_COARSE_LOCATION) != PackageManager.PERMISSION_GRANTED) {

return;
}
Location location = locationManager.getLastKnownLocation(LocationManager.GPS_PROVIDER);
// now get the lat/lon from the location and do something with it.
Toast.makeText(getApplicationContext(), "" + location.getLatitude() + '\n' + location.getLongitude(), Toast.LENGTH_LONG).show();
}
@Override
