在自定义列表视图中长期单击项目后,我需要上下文菜单.我正在使用
ActionBarSherlock.尝试使用Toast通知进行调试,我发现Long Click事件没有被触发.如何解决这个问题？
m_vwJokeLayout=(ListView)findViewById(R.id.jokeListViewGroup);
m_vwJokeLayout.setOnItemLongClickListener(new AdapterView.OnItemLongClickListener() {
@Override
public boolean onItemLongClick(AdapterView<?> parent,View view,int position,long id) {
// TODO Auto-generated method stub
if(m_vwActionMode!=null)
{
Toast.makeText(getApplicationContext(),"Inside On Itemlongclick",Toast.LENGTH_LONG).show();
return false;
}
Toast.makeText(getApplicationContext(),Toast.LENGTH_LONG).show();
m_vwActionMode=getSherlock().startActionMode(m_vwCallback);
view.setSelected(true);
return true;
}
});
下面给出了ListView声明的xml代码：
<?xml version="1.0" encoding="utf-8"?>

android:layout_width="match_parent"

android:layout_width="match_parent"
android:layout_height="wrap_content"
