推荐答案

您还没有解释你的code。因此，它是很难获得通过你的问题。

You haven't explained about your code. So it's difficult to get through your problem.

检查这博客。它可以帮助你。该博客说，大约一个时间选择器的问题。这同样适用于的EditText＆安培; TextView中也。

Check this blog. It may help you. This blog says about a time picker issue. The same applies for EditText & TextView also.

setSaveFromParentEnabled（假）的＆放大器; setSaveEnabled（真）的应该可以解决这个问题。

setSaveFromParentEnabled(false) & setSaveEnabled(true) should solve the issue.

tp = (TimePicker) findViewById(R.id.timePickerComponent);
//two lines to add after
tp.setSaveFromParentEnabled(false);
tp.setSaveEnabled(true);
