Android 使用地图时的权限请求方法

if (ContextCompat.checkSelfPermission(this, Manifest.permission.ACCESS_FINE_LOCATION)   != PackageManager.PERMISSION_GRANTED) {  //申请WRITE_EXTERNAL_STORAGE权限  ActivityCompat.requestPermissions(this, new String[]{Manifest.permission.ACCESS_FINE_LOCATION}, Constants.ACCESS_FINE_LOCATION_COMMANDS_REQUEST_CODE); } else {  /**  * 初始化用户位置  */  setMyLoctionPicture(); }

/**  * 初始化用户位置  */ public void setMyLoctionPicture(){  LogUtils.d(TAG,"setMyLocationPicture() is running");  if(aMap==null){   aMap=mapview.getMap();  }  MyLocationStyle locationStyle = new MyLocationStyle();  locationStyle.myLocationIcon(BitmapDescriptorFactory.fromResource(R.mipmap.location_marker));  locationStyle.strokeColor(Color.BLACK);  locationStyle.radiusFillColor(Color.argb(100, 0, 0, 100));  locationStyle.strokeWidth(1.0f);  aMap.setMyLocationStyle(locationStyle);  aMap.setLocationSource(this);  UiSettings uiSettings = aMap.getUiSettings();  uiSettings .setMyLocationButtonEnabled(true);  aMap.setMyLocationEnabled(true);  aMap.setInfoWindowAdapter(this);  aMap.setOnMarkerClickListener(this); }
