推荐答案

您尚未说明代码.因此很难解决您的问题.

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

查看此博客.它可能会帮助您.该博客介绍了一个时间选择器问题.对于EditText&TextView也.

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

setSaveFromParentEnabled(false) & setSaveEnabled(true) 应该可以解决该问题.

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);
