当我使用longClick时，我想添加一个带有2个按钮的对话框，进行编辑和删除（仅实际删除实现）（标准单击会打开项目详细信息）
所以我尝试遵循this link上的指南
并且我添加了
@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;
}
（其中适配器是我的列表适配器）
我已经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，但是当我长时间单击时，出现此错误（调用
view.showContextMenu();）时应用崩溃：08-02 18:13:12.079: E/AndroidRuntime(7780): FATAL EXCEPTION: main

长按列表项时，该问题有什么解决方案或查看简单上下文对话框的替代方法？
最佳答案
您似乎已经为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，
等等直到堆栈溢出
要解决此问题：
首先，删除OnItemLongClickListener，因为它与ContextMenu无关。
其次，仔细检查您如何使用ContextMenu。您已经将菜单保存在布局文件夹中，并且如果您已经使用过registerForContextMenu（），则无需调用showContextMenu（）。
要设置ContextMenu，只需将整个ListView传递给registerForContextMenu（）：
registerForContextMenu(list);
您将需要这样的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>
将此保存到新文件夹
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，长按一次，每行将自动打开一个ContextMenu。
如果需要有关编辑和删除行的帮助，请发布用于创建ListView和适配器的代码。
