尝试在点击列表项时单击时添加对话框会导致StackOverflow错误

当我使用longClick（标准点击打开项目详细信息）时，我想添加一个带有2个按钮的对话框编辑和删除（仅实际删除实现）

因此我尝试按照this link

上的指南进行操作

我添加了

@Override
public void onCreateContextMenu(ContextMenu menu, View v,
        ContextMenuInfo menuInfo) {
    super.onCreateContextMenu(menu, v, menuInfo);
    MenuInflater inflater = getMenuInflater();
    inflater.inflate(R.layout.edit_dialog, menu);
}

@Override
public boolean onContextItemSelected(MenuItem item) {
    AdapterContextMenuInfo info = (AdapterContextMenuInfo) item
            .getMenuInfo();

    switch (item.getItemId()) {
    case R.id.remove_item:

        final String[] listItem = getItemId();

        String idItemSel = listItem[info.position];

        delItem(idItemSel);
        adapter.notifyDataSetChanged();
        return true;
    }
    return false;
}

（其中 adapter 是我的列表适配器）

我以这种方式配置了监听器

list.setOnItemClickListener(new OnItemClickListener() {

            public void onItemClick(AdapterView<?> parent, View view,
                    int position, long id) {
                .....

            }
        });


        list.setOnItemLongClickListener(new OnItemLongClickListener() {

            public boolean onItemLongClick(AdapterView<?> parent, View view,
                    int position, long id) {
                view.showContextMenu();
                return true;

            }
        });

一切正常，但是当我使用长按时，应用程序崩溃时出现此错误（调用view.showContextMenu();时）：

当我长按列表项时，问题的任何解决方案或查看简单上下文对话框的替代方法？

2 个答案:

答案 0 :(得分：8)

您似乎已经为ContextMenu 注册了ListView，并且设置了一个调用showContextMenu（）的OnItemLongClickListener，这会创建一个循环逻辑：

  • OnItemLongClickListener调用ContextMenu，
  • ContextMenu调用OnItemLongClickListener，
  • OnItemLongClickListener调用ContextMenu，
  • ContextMenu调用OnItemLongClickListener，
  • 等。直到堆栈溢出发生

解决此问题：

首先，删除OnItemLongClickListener，因为它与ContextMenu是多余的。

其次，仔细检查您使用ContextMenu的方式。您已将菜单保存在布局文件夹中，如果已使用registerForContextMenu（），则无需调用showContextMenu（）。

要设置ContextMenu，只需将整个ListView传递给registerForContextMenu（）：

registerForContextMenu(list);

你需要这样的XML：

<menu xmlns:android="http://schemas.android.com/apk/res/android">
    <item
        android:id="@+id/edit"
        android:title="@string/edit" />
    <item
        android:id="@+id/remove"
        android:title="@string/remove" />
</menu>

将其保存在新文件夹res/menu中，我将其命名为context_menu.xml。

然后更改您的方法以创建ContextMenu：

@Override
public void onCreateContextMenu(ContextMenu menu, View v, ContextMenuInfo menuInfo) {
    super.onCreateContextMenu(menu, v, menuInfo);
    getMenuInflater().inflate(R.menu.context_menu, menu);
}

现在每一行都会在长时间点击后自动打开一个ContextMenu。

如果您需要编辑和删除行的帮助，请发布用于创建ListView和适配器的代码。

如果你单击Listview中的Textview（自动链接）然后崩溃删除这个android：textIsSelectable =“true”在我的情况下它解决了。我有同样的错误
