我最近一直在使用 ActionBarSherlock，并遵循各种教程，我编写了这段代码来将项目添加到操作栏

@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次点击。

虽然我确实发现您必须覆盖 onOptionsItemSelected 来处理点击，并且可以使用 switch 语句来区分点击，但大多数教程使用来自他们的 xml 菜单的项目 ID。由于我没有在 xml 中创建菜单，我如何区分没有 ID 的点击。

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);
    }
}

只需检查以下

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);
    }
}

您可以通过 onOptionsItemSelected 中的 Id 进行 ti ......也可以在此处设置
