如何区分两个菜单项的点击中ActionBarSherlock？(How to distinguish

我一直在与ActionBarSherlock最近，和follwing各种教程，我写了这个代码将项目添加到行动吧

@Override
public boolean onCreateOptionsMenu(Menu menu) {

    menu.add("Refresh")
        .setIcon(R.drawable.ic_action_refresh)
        .setShowAsAction(MenuItem.SHOW_AS_ACTION_ALWAYS);


    menu.add("Search")// Search
        .setIcon(R.drawable.ic_action_search)
        .setShowAsAction(MenuItem.SHOW_AS_ACTION_ALWAYS);
        return true;
}

但是，我不知道如何区分这两个点击。

虽然我没有发现，你必须重写onOptionsItemSelected处理点击，也是一个switch语句可以用点击来区分，但大多数教程使用项ID从thier XML的菜单。 因为我不是在XML中创建菜单我如何可以区分点击无标识。

Answer 1:

private static final int REFRESH = 1;
private static final int SEARCH = 2;

@Override
public boolean onCreateOptionsMenu(Menu menu) {

    menu.add(0, REFRESH, 0, "Refresh")
        .setIcon(R.drawable.ic_action_refresh)
        .setShowAsAction(MenuItem.SHOW_AS_ACTION_ALWAYS);


    menu.add(0, SEARCH, 0, "Search")
        .setIcon(R.drawable.ic_action_search)
        .setShowAsAction(MenuItem.SHOW_AS_ACTION_ALWAYS);
        return true;
}

@Override
public boolean onOptionsItemSelected(MenuItem item) {
    switch (item.getItemId()) {
        case REFRESH:
            // Do refresh
            return true;
        case SEARCH:
            // Do search
            return true;
        default:
            return super.onOptionsItemSelected(item);
    }
}

Answer 2:

只要检查以下

http://developer.android.com/guide/topics/ui/actionbar.html

其中包含

@Override
public boolean onOptionsItemSelected(MenuItem item) {
    switch (item.getItemId()) {   <--- here you can get it
        case android.R.id.home:
            // app icon in action bar clicked; go home
            Intent intent = new Intent(this, HomeActivity.class);
            intent.addFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP);
            startActivity(intent);
            return true;
        default:
            return super.onOptionsItemSelected(item);
    }
}

Answer 3:

您可以通过有标识在onOptionsItemSelected ................可以在这里还可以设置做TI
