DatePickerDialog的OnDateSetListener被调用两次的bug解决方案

使用DatePickerDialog.OnDateSetListener的时候发现回调了两次。原因貌似源码的问题。

解决方案：

判断下view是否显示着

final Context context = MainActivity.this; Calendar calendar = Calendar.getInstance(); int y = calendar.get(Calendar.YEAR); int m = calendar.get(Calendar.MONTH); int d = calendar.get(Calendar.DAY_OF_MONTH); DatePickerDialog.OnDateSetListener onDateSetListener = new DatePickerDialog.OnDateSetListener() { @Override public void onDateSet(DatePicker view, int year, int month, int dayOfMonth) { if (view.isShown()) { // 这里判断 Toast.makeText(context, String.format(Locale.CHINA, "(y, m, d) = (%d, %d, %d)", year, month, dayOfMonth), Toast.LENGTH_SHORT).show(); } } }; DatePickerDialog datePickerDialog = new DatePickerDialog(context, onDateSetListener, y, m, d); datePickerDialog.show();
