問題描述
我有以下問題:
我有一個現有的 ListFragment，但我想將其顯示為對話框.
I have an exisiting ListFragment, but I would like to display this as a dialog.
我的第一種方法是創建一個 DialogFragment，它必須在其中 ListFragment，但目前似乎無法將片段放入片段中.
My first approach was to create a DialogFragment which has to ListFragment inside of it, but appearently it is currently not possible to put fragments in fragments.
擴展 DialogFragment 而不是 ListFragment 也是不可能的，因為大量使用了 ListFragment 方法.
Extending DialogFragment instead of ListFragment is also not possible, because of the heavy use of ListFragment methods.
有沒有簡單的方法可以做到這一點?
Is there an easy way to do this?
推薦答案
對我有用的是
1) 在 DialogFragment 的 xml 布局中調用，比如說 DialogFragmentwWithListFragment 指定 ListFragment 類
例如.dialog_fragment_with_list_fragment.xml:
What works for me is
1) in xml layout for your DialogFragment called, let's say, DialogFragmentwWithListFragment specify ListFragment class
E.g. dialog_fragment_with_list_fragment.xml :
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent">
<fragment
android:id="@+id/flContent"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:padding = "10dp"
class="com.xxx.yyy.DialogFragmentwWithListFragment " />
</LinearLayout>
2) 在 DialogFragmentwWithListFragment 中膨脹 dialog_fragment_with_list_fragment.xml
@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
return inflater.inflate(R.layout.dialog_fragment_with_list_fragment, null);
}
3) 調用 DialogFragmentwWithListFragment 作為常規 DialogFragment:
3) invoke DialogFragmentwWithListFragment as regular DialogFragment:
DialogFragmentwWithListFragment dialogFragment = DialogFragmentwWithListFragment .newInstance();
dialogFragment.setRetainInstance(true);
dialogFragment.show(getFragmentManager(), "tag");
希望，它會有所幫助.
Hope, it helps.
