android - "onMenuItemSelected"和 "onOptionsItemSelected"之间的区别

Question

谁能解释一下两者的区别:

onMenuItemSelected (int featureId, MenuItem item)
http://developer.android.com/reference/android/app/Activity.html#onMenuItemSelected%28int,%20android.view.MenuItem%29

和

onOptionsItemSelected(MenuItem 项)
http://developer.android.com/reference/android/app/Activity.html#onOptionsItemSelected%28android.view.MenuItem%29

在安卓系统中？我发现一个教程有人重写了这两种方法。

// Reaction to the menu selection
@Override
public boolean onMenuItemSelected(int featureId, MenuItem item) {
    switch (item.getItemId()) {
    case R.id.insert:
        createTodo();
        return true;
    }
    return super.onMenuItemSelected(featureId, item);
}

@Override
public boolean onOptionsItemSelected(MenuItem item) {
    switch (item.getItemId()) {
    case R.id.insert:
        createTodo();
        return true;
    }
    return super.onOptionsItemSelected(item);
}

Android 知道几种类型的菜单(例如，选项菜单和上下文菜单)。 onMenuItemSelected 是通用回调。您通常不需要使用它。 onOptionsItemSelected 是选项菜单的回调，onContextItemSelected 是上下文菜单的回调。请改用这两个特定的。
