开启监听:

// Location Listener
		LocationListener.getInstance(getApplicationContext()).setLocationListener();

异步获取：

private class GetMyLocation extends AsyncTask<Void, Void, String> {

		private ProgressDialog progressDialog;

		public GetMyLocation() {
			progressDialog = new ProgressDialog(EmergencyContactDetailActivity.this);
			progressDialog.show();
		}

		@Override
		protected String doInBackground(Void... params) {
			String address = null;
			try {
				address = LocationListener.getInstance(getApplicationContext()).getAddress();
			} catch (Exception e) {
				Logging.e("GetMyLocation Error", e.getMessage());
			}
			return address;
		}

		@Override
		protected void onPostExecute(String result) {
			if (progressDialog != null && progressDialog.isShowing()) {
				progressDialog.cancel();
			}
		textview.setText(result);
		}
	}
