如何在自定义对话框中使用回收器视图[重复]

Question

如何在Android警报对话框中显示列表视图？我试过了。

Answer 1

您应该扩展DialogFragment并创建自定义对话框，其中将包含回收器视图。

布局：-fragment_dialog.xml

<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent"
    android:layout_height="match_parent" >

  <android.support.v7.widget.RecyclerView
    android:id="@+id/recycler_view"
    android:scrollbars="vertical"
    android:layout_width="match_parent"
    android:layout_height="match_parent"/>

</RelativeLayout>

您的自定义对话框：-MyDialogFragment

public class MyDialogFragment extends DialogFragment {
    private RecyclerView mRecyclerView;
    // this method create view for your Dialog
    @Override
    public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
          //inflate layout with recycler view
         View v = inflater.inflate(R.layout.fragment_dialog, container, false);
        mRecyclerView = (RecyclerView) v.findViewById(R.id.recycler_view);
        //setadapter
         //get your recycler view and populate it.
         return v;
    }
}

Answer 2

试试这个：

自定义_对话框。xml

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:orientation="vertical"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content">

   <android.support.v7.widget.RecyclerView
    android:id="@+id/my_recycler_view"
    android:scrollbars="vertical"
    android:layout_width="match_parent"
    android:layout_height="match_parent"/>
</LinearLayout>

活动/片段。JAVA

RecyclerView mRecyclerView; 
AlertDialog.Builder builder = new AlertDialog.Builder(context); 
LayoutInflater inflater = LayoutInflater.from(context);
View content = inflater.inflate(R.layout.custom_dialog, null);
builder.setView(content); 
mRecyclerView = (RecyclerView) content.findViewById(R.id.my_recycler_view);
