找不到符号方法getSupportFragmentManager（）

Question

在主要活动中我有这个

public void showTimePickerDialog(View v) {
    DialogFragment newFragment = new uSharedUtility.TimePickerFragment();
    newFragment.show(getSupportFragmentManager(), "timePicker");
}

但是我收到了这个错误：

Error:(566, 26) error: cannot find symbol method getSupportFragmentManager()

搜索后我发现我可以让它消失by extending from FragmentActivity

但是由于之前的一些要求，目前我的MainActivity正在从public class Main extends ListActivity延伸。

除了更改扩展类之外，还有其他任何方法可以解决此问题吗？

Answer 1

getSupportFragmentManager（） 是 FragmentActivity 的方法。您的父活动应该扩展FragmentActivity

检查

Answer 2

There are other reasons for the same error message. You might need to instead call getFragmentManager()
