}
public void OnCreateContextMenu(ContextMenu menu, View v, ContextMenuInfo menuInfo){
    super.onCreateContextMenu(menu, v, menuInfo);
    menu.add(R.id.item1);
    menu.add(R.id.item2);
    MenuInflater inflater = getMenuInflater();
    inflater.inflate(R.menu.context_menu,  menu);

}
@Override
public boolean onContextItemSelected(MenuItem item){
    AdapterContextMenuInfo info = (AdapterContextMenuInfo) item.getMenuInfo();
    switch(item.getItemId()){
    case R.id.item1:
        Intent smsIntent = new Intent(Intent.ACTION_VIEW);
        smsIntent.putExtra("sms_body",  "TU-Do List Item: " + mAdapter.getItem((int)info.id));
        smsIntent.putExtra("address",  "2924699");
        smsIntent.setType("vnd.android-dir/mms-sms");
        startActivity(smsIntent);
        return true;
    case R.id.item2:
        Intent emailIntent = new Intent(android.content.Intent.ACTION_SEND);
        emailIntent.putExtra(android.content.Intent.EXTRA_EMAIL,  "cosc490spring2014@gmail.com");
        emailIntent.putExtra(android.content.Intent.EXTRA_SUBJECT,  "New TU-Do Item");
        emailIntent.setType("plain/text");
        emailIntent.putExtra(android.content.Intent.EXTRA_TEXT,  mAdapter.getItem((int)info.id));
        startActivity(emailIntent);
        return true;
    default:
        return super.onContextItemSelected(item);
    }
}

所以我把这个代码放到了我的android应用程序

我不明白为什么当我点击我的listview时，contextMenu仍然不会弹出。任何帮助将不胜感激

好的，因为这非常简单，但是添加一个有效的onClickListener也会有所帮助。

onCreateContextMenu必须使用小字母编写。

@Override
public void onCreateContextMenu(ContextMenu menu, View v, ContextMenuInfo menuInfo)...
