材料设计中的全屏对话框应该在操作栏/工具栏上进行确认和解除操作.
我的问题,我该怎么办?
显示对话框:
getFragmentManager().beginTransaction() .add(R.id.container,new MyDialogFragment()) .addToBackStack(null).commit();
我的对话片段:
public class MyDialogFragment extends DialogFragment { @Override public View onCreateView(LayoutInflater inflater,ViewGroup container,Bundle savedInstanceState) { return inflater.inflate(R.layout.fragment_layout,container,false); } }
解决方法
只需要做两件事情:
更改图标:
@Override public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setHasOptionsMenu(true); ((ActionBarActivity) getActivity()).getSupportActionBar().setDisplayHomeAsUpEnabled(true); ((ActionBarActivity) getActivity()).getSupportActionBar().setHomeAsUpIndicator(android.R.drawable.ic_menu_close_clear_cancel); }
@Override public void onCreateOptionsMenu(Menu menu,MenuInflater inflater) { inflater.inflate(R.menu.save_menu,menu); }
R.menu.save_menu:
<?xml version="1.0" encoding="utf-8"?> <menu xmlns:app="http://schemas.android.com/apk/res-auto" xmlns:android="http://schemas.android.com/apk/res/android"> <item android:id="@+id/save app:showAsAction="always|withText" android:title="@string/save"/> </menu>
