不使用地圖jar包擷取當前位置的方法

開啟監聽:

// Location ListenerLocationListener.getInstance(getApplicationContext()).setLocationListener();

非同步擷取：

private class GetMyLocation extends AsyncTask<Void, Void, String> {private ProgressDialog progressDialog;public GetMyLocation() {progressDialog = new ProgressDialog(EmergencyContactDetailActivity.this);progressDialog.show();}@Overrideprotected String doInBackground(Void... params) {String address = null;try {address = LocationListener.getInstance(getApplicationContext()).getAddress();} catch (Exception e) {Logging.e("GetMyLocation Error", e.getMessage());}return address;}@Overrideprotected void onPostExecute(String result) {if (progressDialog != null && progressDialog.isShowing()) {progressDialog.cancel();}textview.setText(result);}}
