在看 Android Dev Guide，目前卡在 Action Bar 这里...

这两天在看Android开发，现在的情况就是，我按照Guide上的做了，但是Action Bar上的自定义Activity显示不出来，一直只有一个默认的Settings... 似乎把xml里面关于setting的action删掉都还是只会显示settings...... 于是我在MyActivity里加入了按下各个Activity都会产生Toast的代码，依然只有Settings显示出来，而且按下之后会显示Toast。开发环境是brew下来的Android Studio，然后运行环境是Android 5.1 @ Nexus 5。啊还有在main_activity_actions.xml里，Android Studio一只提示让我用app:showAsAction，然而我让他自动补全之后依然显示不出来。不知道这里是什么问题，萌新要被搞哭了qwq。谢谢各位><

main_activity_actions.xml

<menu xmlns:android="http://schemas.android.com/apk/res/android">
<!-- Search, should appear as action button -->
<item android:id="@+id/action_search"
    android:icon="@drawable/ic_action_search"
    android:title="@string/action_search"
    android:showAsAction="never"/>
<!-- Settings, should always be in the overflow -->
 <item android:id="@+id/action_settings"
    android:title="@string/action_settings"
    android:icon="@drawable/ic_action_settings"
    android:showAsAction="never"/>
</menu>

MyActivity.java

@Override
public boolean onOptionsItemSelected(MenuItem item) {
    // Handle action bar item clicks here. The action bar will
    // automatically handle clicks on the Home/Up button, so long
    // as you specify a parent activity in AndroidManifest.xml.
    int id = item.getItemId();

    //noinspection SimplifiableIfStatement
    if (id == R.id.action_settings) {
        Toast.makeText(getApplicationContext(), "lol", Toast.LENGTH_LONG).show();
        return true;
    }

    if (id == R.id.action_search) {
        Toast.makeText(getApplicationContext(), "lol", Toast.LENGTH_LONG).show();
        return true;
    }

    return super.onOptionsItemSelected(item);
}
