从xml解析数组以及右键菜单找到点击位置-优快云博客

本文介绍了一个简单的上下文菜单实现方式，通过重写onCreateContextMenu和onContextItemSelected方法，为列表视图中的每一项添加了编辑和删除选项，并实现了相应的功能。

1.mTestArray = = getResources().getStringArray(R.array.testArray);

2.右键菜单和主菜单有些区别

switch(item.getItemId())
{
case 0:
ShowAlert("hello from delete item");
break;
default:
return super.onContextItemSelected(item);
}
return true;

这样子就好

private static final int EDIT_ID = Menu.FIRST + 3;
private static final int DELETE_ID = Menu.FIRST + 4;
@Override
public void onCreateContextMenu(ContextMenu menu, View v,
ContextMenu.ContextMenuInfo menuInfo) {
menu.add(Menu.NONE, EDIT_ID, Menu.NONE, "Edit").setAlphabeticShortcut(
'e');
menu.add(Menu.NONE, DELETE_ID, Menu.NONE, "Delete")
.setAlphabeticShortcut('d');
}

@Override
public boolean onContextItemSelected(MenuItem item) {
AdapterView.AdapterContextMenuInfo info = (AdapterView.AdapterContextMenuInfo) item .getMenuInfo();
switch (item.getItemId()) {
case EDIT_ID:

edit(info.id);
return (true);
case DELETE_ID:

delete(info.id);
return (true);
}

return (super.onOptionsItemSelected(item));
}

或者

@Override
public boolean onContextItemSelected(MenuItem item) {
AdapterContextMenuInfo info = (AdapterContextMenuInfo) item.getMenuInfo();
int index = info.position;
View view = info.targetView;
}
