添加menu

增加文件 res/menu/menu_main.xml:

<?xml version="1.0" encoding="utf-8"?>
<menu xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:app="http://schemas.android.com/apk/res-auto">

    <item android:id="@+id/id_action_add"
        android:orderInCategory="100"
        android:title="add"
        app:showAsAction="ifRoom"
        android:icon="@mipmap/as_actionbar_add_icon"></item>

    <item android:id="@+id/id_action_delete"
        android:orderInCategory="100"
        android:title="delete"
        app:showAsAction="ifRoom"
        android:icon="@mipmap/as_ic_menu_delete"></item>

    <item android:id="@+id/id_action_gridview"
        android:orderInCategory="100"
        android:title="GirdView"
        app:showAsAction="never"></item>

    <item android:id="@+id/id_action_listview"
        android:orderInCategory="100"
        android:title="ListView"
        app:showAsAction="never"></item>

    <item android:id="@+id/id_action_horizontalGridView"
        android:orderInCategory="100"
        android:title="HorizontalGridView"
        app:showAsAction="never"></item>

</menu>

在 MainActivity.java 处添加以下内容:

    @Override
    public boolean onCreateOptionsMenu(Menu menu) {
        getMenuInflater().inflate(R.menu.menu_main, menu);
        return super.onCreateOptionsMenu(menu);
    }

    @Override
    public boolean onOptionsItemSelected(MenuItem item) {
        switch (item.getItemId()) {
            case R.id.id_action_add:
                adatper.addData(0, "新名字");
                break;
            case R.id.id_action_delete:
                adatper.removeData(1);
                break;
            case R.id.id_action_gridview:
                recyclerView.setLayoutManager(new GridLayoutManager(this, 2));
                break;
            case R.id.id_action_listview:
                recyclerView.setLayoutManager(new LinearLayoutManager(this));
                break;
            case R.id.id_action_horizontalGridView:
                recyclerView.setLayoutManager(new StaggeredGridLayoutManager(2, StaggeredGridLayoutManager.HORIZONTAL));
                break;
        }

        return true;
    }
