为什么要使用库？它在Android框架中很简单。只需在xml中创建一个菜单并在代码中充气即可。下面是my_toolbar_menu.xml：

<?xml version="1.0" encoding="utf-8"?>
<menu xmlns:android="http://schemas.android.com/apk/res/android">
    <item android:id="@+id/add_menu"
          android:icon="@drawable/ic_add_icon"
          android:title="@string/add_text"
          android:showAsAction="ifRoom"/>
    <item android:id="@+id/help"
          android:icon="@drawable/ic_help"
          android:title="@string/help" />
</menu>

现在膨胀菜单：

 @Override
    public boolean onCreateOptionsMenu(Menu menu) {
        MenuInflater inflater = getMenuInflater();
        inflater.inflate(R.menu.my_toolbar_menu, menu);
        return true;
    }

现在处理点击事件，如下所示：

@Override
public boolean onOptionsItemSelected(MenuItem item) {
    // Handle item selection
    switch (item.getItemId()) {
    case R.id.add_menu:
        doSomething();
        return true;
    case R.id.help:
        getHelp();
        return true;
    default:
        return super.onOptionsItemSelected(item);
    }
}

如何在工具栏中的每个菜单上实现onclick事件我使用了TapTargetview库
