android - Android のさまざまなアクティビティで FrameLayout スライダーを呼び出す方法

Question

私は3つのアクティビティを持っています.FrameLayoutを使用してスライダーを開きました. first_activity!second_activitythird_activity

ここで、3 つのアクティビティすべてで使用できるボタンをクリックしてスライダーを開きたいと思います。

テスト1のように、3つのアクティビティすべてと同じように左側にボタンがあるので、それをクリックするとスライダーが開きます。

これは私のスライダーコードです

public class MainActivity extends Activity {

    // Within which the entire activity is enclosed
    private DrawerLayout mDrawerLayout;

    // ListView represents Navigation Drawer
    private ListView mDrawerList;

    // ActionBarDrawerToggle indicates the presence of Navigation Drawer in the
    // action bar
    private ActionBarDrawerToggle mDrawerToggle;

    // Title of the action bar
    private String mTitle = "";

    @SuppressLint("NewApi")
    @Override
    protected void onCreate(Bundle savedInstanceState) {

        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);

        mTitle = "Test App";
        getActionBar().setTitle(mTitle);

        // Getting reference to the DrawerLayout
        mDrawerLayout = (DrawerLayout) findViewById(R.id.drawer_layout);
        mDrawerList = (ListView) findViewById(R.id.drawer_list);

        // Getting reference to the ActionBarDrawerToggle
        mDrawerToggle = new ActionBarDrawerToggle(this, mDrawerLayout,
                R.drawable.ic_drawer, R.string.drawer_open,
                R.string.drawer_close) {

            /** Called when drawer is closed */
