Question

我有一个列表视图，我已成功将列表本身设为可点击。现在在列表中，我也有一个按钮。我尝试了很多方法，但我无法点击按钮。这是我的列表的样子

========================================
content 1               [button remove]
========================================
content 2               [button remove]
========================================
content 3               [button remove]
========================================

我可以将内容（例如：内容1，内容2）点击;单击内容本身时，我已成功打开一个对话框。现在我想让[button remove]也可以点击，这应该会触发一个toast。然而，无论我尝试什么，似乎我无法让我的应用程序检测到已经点击了按钮删除。

这是我的代码的一部分： mylist.xml

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:orientation="horizontal" android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:padding="4dip">

    <TextView
        android:layout_width="0dip"
        android:layout_height="wrap_content"
        android:layout_weight="0.4"
        android:id="@+id/tvDescription" />

    <TextView
        android:layout_width="0dip"
        android:layout_height="wrap_content"
        android:layout_weight="0.1"
        android:id="@+id/tvRating" />

    <Button
        style="?android:attr/buttonStyleSmall"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:text="Remove"
        android:focusable="false"
        android:clickable="true"
        android:id="@+id/btnRemoveExpenses" />


</LinearLayout>

daily.xml

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:orientation="vertical" android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:paddingTop="50dip"
    android:paddingLeft="10dp"
    android:paddingRight="10dp"
    android:id="@+id/ll_expensesDaily"
    android:baselineAligned="false">
    <ListView
            android:id="@android:id/list"
            android:layout_width="fill_parent"
            android:layout_height="wrap_content">
        </ListView>
</LinearLayout>

MyOwnList.java

    private ListView lvExpenses;
public class MyOwnList extends Fragment{
     @Override
    public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState){
        final View rootView = inflater.inflate(R.layout.daily, container, false);

lvExpenses = (ListView) rootView.findViewById(android.R.id.list);
         lvExpenses.setItemsCanFocus(true);
lvExpenses.setOnItemClickListener(expensesClickHandler);
return rootView;
}

private AdapterView.OnItemClickListener expensesClickHandler = new AdapterView.OnItemClickListener() {
        public void onItemClick(AdapterView parent, View v, int position, long id)
        {
            Toast.makeText(getActivity(), " i: " + position + " long: " + id, Toast.LENGTH_SHORT).show();
            showEditExpensesDialog(expensesID.get(position));
        }
    };
}

Answer 1

也许您应该使用SwipeToDimissUndoList而不是那些按钮.. 看这里： https://github.com/timroes/SwipeToDismissUndoList

这是一个样本 -

SwipeDismissList.OnDismissCallback callback = new SwipeDismissList.OnDismissCallback() {
// Gets called whenever the user deletes an item.
public SwipeDismissList.Undoable onDismiss(AbsListView listView, final int position) {
    // Get your item from the adapter (mAdapter being an adapter for MyItem objects)
    final MyItem deletedItem = mAdapter.getItem(position);
    // Delete item from adapter
    mAdapter.remove(deletedItem);
    // Return an Undoable implementing every method
    return new SwipeDismissList.Undoable() {

        // Method is called when user undoes this deletion
        public void undo() {
            // Reinsert item to list
            mAdapter.insert(deletedItem, position)
        }

        // Return an undo message for that item
        public String getTitle() {
            return deletedItem.toString() + " deleted";
        }

        // Called when user cannot undo the action anymore
        public void discard() {
            // Use this place to e.g. delete the item from database
            finallyDeleteFromSomeStorage(deletedItem);
        }
    };
}

};

Answer 2

在适配器的按钮上添加一个on click侦听器。

Answer 3

我会忽略on item click侦听器并在xml中执行。

添加到按钮：android：onClick =“removeBtnClicked”

添加到活动代码：

public void removeBtnClicked(View v){
   //Do something in here to remove row / set the row visibility to gone
}

制作按钮＆amp;列表视图中的列表可点击
