我正在使用时间片段。点击edittext框后，我打开了这样的时间选择器。
final FragmentManager fm = getFragmentManager();
timE.setOnClickListener(new OnClickListener() {
@TargetApi(Build.VERSION_CODES.HONEYCOMB)
@SuppressWarnings("deprecation")
public void onClick(View v) {
FragmentManager fm = getFragmentManager();
dialogFragment2=new DateTimeDialogFragment(ActivityGroup4.context ,2);
dialogFragment2.setContextandView(appState,vi,timE);
System.out.println(vi+" view from meeting list ");
dialogFragment2.setRetainInstance(true);
dialogFragment2.show(fm, "fragment_name");
}
});
这导致时间选择器打开。这里appState是上下文对象，vi是可扩展列表适配器groupchildview方法的视图对象，用于访问edittext片段类中的datetime
在DateTimeDialogFragment中，当选择器打开并单击设置按钮时，我们会获得该值，但此值不会显示在上一个活动的edittext框中
