Question

我的应用程序在dialogFragment中有listview，当用户选择了应该Toast的项目时，我的案例项目无法点击。

DialogueFragment

public class HistoryDialogue extends DialogFragment  {

ListView list ;
Cursor c ;
HistoryAdapter adapter ;
Context context ;



@Override
public Dialog onCreateDialog(Bundle savedInstanceState) {
    LayoutInflater inflater = getActivity().getLayoutInflater();

    View view  = inflater.inflate(R.layout.history,null);
    list = (ListView)view.findViewById(R.id.listView);

    AlertDialog.Builder builder = new AlertDialog.Builder(getActivity());

     ContentResolver resolver = getActivity().getContentResolver();
     c=resolver.query(Contract.SaveRunning.CONTENT_URI,null,null,null,null);
     adapter= new HistoryAdapter(getActivity(),c,0);
     list.setAdapter(adapter);
     list.setOnItemClickListener(new AdapterView.OnItemClickListener() {
         @Override
         public void onItemClick(AdapterView<?> parent, View view, int position, long id) {
             Toast.makeText(getActivity(),"keep going ",Toast.LENGTH_LONG).show();
         }
     });

    builder.setView(list);
    return builder.create();

}

}

的CursorAdapter

public class HistoryAdapter extends CursorAdapter {
public HistoryAdapter(Context context, Cursor c, int flags) {
    super(context,c, flags);
}

@Override
public View newView(Context context, Cursor cursor, ViewGroup parent) {
    return LayoutInflater.from(context).inflate(R.layout.historylist, parent, false);
}

@Override
public void bindView(View view, Context context, Cursor cursor) {
    TextView text = (TextView) view.findViewById(R.id.text);
    String body = cursor.getString(cursor.getColumnIndex("name"));
    text.setText(body);

}

}

history.xml

    <ListView
    xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:id="@+id/listView"
    android:layout_gravity="center_horizontal" />

historylist.xml

<LinearLayout
xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="horizontal"
android:layout_width="match_parent"
android:layout_height="60dp">

    <TextView
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        android:id="@+id/text"
        android:layout_margin="5dp"
        android:layout_weight="1"/>

    <Button
        android:layout_width="30dp"
        android:layout_height="35dp"
        android:background="@drawable/delete"
        android:id="@+id/btn"
        android:layout_margin="10dp"
        android:layout_weight="0"
        />

Answer 1

将此行添加到CursorAdapter的bindView：

((ViewGroup)row).setDescendantFocusability(ViewGroup.FOCUS_BLOCK_DESCENDANTS);

如果不够，请将clickable="false"添加到historylist.xml按钮

DialogueFragment里面的Listview无法点击
