Finally, I find a solution: I create a thread and wait for my location available.

@Override
public void onActivityResult(int requestCode, int resultCode, Intent data) {
    switch (requestCode){
        case REQUEST_LOCATION:
            switch (resultCode){
                case Activity.RESULT_OK:
                    mHandler = new Handler();
                    runnable = new Runnable() {
                        @Override
                        public void run() {
                            mHandler.postDelayed(this,1000);
                            checkLocationAvailable();
                        }
                    };
                    mHandler.postDelayed(runnable,1000);
                    break;
                case Activity.RESULT_CANCELED:
                    break;
            }
    }
}

Create a function to stop the thread when my location available.

private void checkLocationAvailable(){
  if (mMap.getMyLocation() != null) {
  mHandler.removeCallbacks(runnable);
  // do stuff
  }
}

It is not a good solution, but hope it will help.
