尝试在点击列表项时单击时添加对话框会导致StackOverflow错误

Question

我想在使用longClick时添加带有2个按钮的对话框编辑和删除(仅实际删除实现)(标准点击打开项目详细信息)

所以我试图按照这个链接上的指南

我补充说

@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;
}

(其中适配器是我的列表适配器)

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,应用程序崩溃并出现此错误(在调用时view.showContextMenu();):

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案？

Answer 1

您似乎已为ContextMenu注册了ListView 并设置了一个调用showContextMenu()的OnItemLongClickListener,这将创建一个循环逻辑:

• OnItemLongClickListener调用ContextMenu,
• ContextMenu调用OnItemLongClickListener,
• OnItemLongClickListener调用ContextMenu,
• ContextMenu调用OnItemLongClickListener,
• 等,直到堆栈溢出

解决这个问题:

首先,删除OnItemLongClickListener,因为它与ContextMenu是冗余的.

其次,仔细检查您如何使用ContextMenu.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>

将其保存在一个新文件夹中res/menu,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);
}

现在每个行都会在长按时自动打开ContextMenu.
