我要求成功接收 FINE 和 COARSE 权限。然后构建GoogleAPIClient并创建LocationRequest，然后FusedLocationApi.getLastLocation，它继续返回null。我知道在询问位置之前应该建立连接。因为建立连接的onStart()是在retrieveLocation()方法之后调用的，所以在构建mLocationApiClient.connect()方法后立即调用GoogleApiClient. onConnected并且当我检查mLocationApiClient.isConnected（）时，它说'真正'。然后，当我尝试使用LastLocation检索FusedLocationApi时，它始终返回null。我感到困惑，因为我已多次检查并且有连接但没有检索到位置。我哪里错了？

在您的活动中，请按以下步骤操作
创建并初始化LocationResolver变量
private LocationResolver mLocationResolver;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
mLocationResolver=new LocationResolver(this);
}
并将这些行添加到您的活动中
@Override
protected void onStart() {
super.onStart();
mLocationResolver.onStart();
}
@Override
protected void onStop() {
super.onStop();
mLocationResolver.onStop();
}
@Override
protected void onDestroy() {
super.onDestroy();
mLocationResolver.onDestroy();
}
@Override
public void onRequestPermissionsResult(int requestCode, @NonNull String[] permissions, @NonNull int[] grantResults) {
super.onRequestPermissionsResult(requestCode, permissions, grantResults);
mLocationResolver.onRequestPermissionsResult(requestCode, permissions, grantResults);
}
用法：当您想要位置时，使用此代码获取位置
void retrieveLocation() {
mLocationResolver.resolveLocation(this, new LocationResolver.OnLocationResolved() {
@Override
public void onLocationResolved(Location location) {
// Do what ever you want
}
});
}
