如何在线性布局中开始新活动？

Question

我有三个布局文件。一个名为activity_home，另一个名为activity_main，另一个名为activity_test。 activity_main只是一个简单的布局，包含单个textview和一个按钮。 activity_test是一个单独的布局文件，其中textview表示hello world.activity_home如下所示。

<android.support.v4.widget.DrawerLayout
xmlns:android="http://schemas.android.com/apk/res/android"
android:id="@+id/drawer_layout"
android:layout_width="match_parent"
android:layout_height="match_parent">

<com.example.shan.real_connect.widget.RevealFrameLayout
    android:id="@+id/conteiner_frame"
    xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent"
    android:layout_height="match_parent">
    <LinearLayout
        android:id="@+id/content_overlay"
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        android:orientation="vertical"/>
    <LinearLayout
        android:id="@+id/content_frame"
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        android:orientation="vertical"/>

    <android.support.v7.widget.Toolbar
        android:id="@+id/toolbar"
        android:layout_height="wrap_content"
        android:layout_width="match_parent"
        android:minHeight="?attr/actionBarSize"
        android:background="?attr/colorPrimary"/>

</com.example.shan.real_connect.widget.RevealFrameLayout>

<ScrollView
    android:id="@+id/scrollView"
    android:scrollbarThumbVertical="@android:color/transparent"
    android:layout_width="80dp"
    android:layout_height="match_parent"
    android:layout_gravity="start|bottom">

    <LinearLayout
        android:id="@+id/left_drawer"
        android:orientation="vertical"
        android:layout_width="80dp"
        android:layout_height="wrap_content"
        android:divider="@android:color/transparent"
        android:dividerHeight="0dp"
        android:background="@android:color/transparent">
        <!-- Layout of Drawer -->
    </LinearLayout>
</ScrollView>
</android.support.v4.widget.DrawerLayout>

当我点击主要活动中的按钮时，我想打开我的activity_home并将我的activity_test加载到activity_home内名为“content_frame”的线性布局中。我该怎么办？我的home.java文件的代码也在下面。

public class Home extends ActionBarActivity implements ViewAnimator.ViewAnimatorListener,View.OnClickListener {
    private DrawerLayout drawerLayout;
    private ActionBarDrawerToggle drawerToggle;
    private List<SlideMenuItem> list = new ArrayList<>();
    private ContentFragment contentFragment;
    private ViewAnimator viewAnimator;
    private int res = R.drawable.content_music;
    private LinearLayout linearLayout;


    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_home);

        contentFragment = ContentFragment.newInstance(R.drawable.content_music);
        getSupportFragmentManager().beginTransaction()
                .replace(R.id.content_frame, contentFragment)
                .commit();
        drawerLayout = (DrawerLayout) findViewById(R.id.drawer_layout);
        drawerLayout.setScrimColor(Color.TRANSPARENT);
        linearLayout = (LinearLayout) findViewById(R.id.left_drawer);
        linearLayout.setOnClickListener(this);


        setActionBar();
        createMenuList();
        viewAnimator = new ViewAnimator<>(this, list, contentFragment, drawerLayout, this);
    }

    private void createMenuList() {
        SlideMenuItem menuItem0 = new SlideMenuItem(ContentFragment.CLOSE, R.drawable.icn_close);
        list.add(menuItem0);
        SlideMenuItem menuItem = new SlideMenuItem(ContentFragment.BUILDING, R.drawable.icn_1);
        list.add(menuItem);
        SlideMenuItem menuItem2 = new SlideMenuItem(ContentFragment.BOOK, R.drawable.icn_2);
        list.add(menuItem2);
        SlideMenuItem menuItem3 = new SlideMenuItem(ContentFragment.PAINT, R.drawable.icn_3);
        list.add(menuItem3);
        SlideMenuItem menuItem4 = new SlideMenuItem(ContentFragment.CASE, R.drawable.icn_4);
        list.add(menuItem4);
        SlideMenuItem menuItem5 = new SlideMenuItem(ContentFragment.SHOP, R.drawable.icn_5);
        list.add(menuItem5);
        SlideMenuItem menuItem6 = new SlideMenuItem(ContentFragment.PARTY, R.drawable.icn_6);
        list.add(menuItem6);
        SlideMenuItem menuItem7 = new SlideMenuItem(ContentFragment.MOVIE, R.drawable.icn_7);
        list.add(menuItem7);
    }


    private void setActionBar() {
        Toolbar toolbar = (Toolbar) findViewById(R.id.toolbar);
        setSupportActionBar(toolbar);
        getSupportActionBar().setHomeButtonEnabled(true);
        getSupportActionBar().setDisplayHomeAsUpEnabled(true);
        drawerToggle = new ActionBarDrawerToggle(
                this,                  /* host Activity */
                drawerLayout,         /* DrawerLayout object */
                toolbar,  /* nav drawer icon to replace 'Up' caret */
                R.string.drawer_open,  /* "open drawer" description */
                R.string.drawer_close  /* "close drawer" description */
        ) {

            /** Called when a drawer has settled in a completely closed state. */
            public void onDrawerClosed(View view) {
                super.onDrawerClosed(view);
                linearLayout.removeAllViews();
                linearLayout.invalidate();
            }

            @Override
            public void onDrawerSlide(View drawerView, float slideOffset) {
                super.onDrawerSlide(drawerView, slideOffset);
                if (slideOffset > 0.6 && linearLayout.getChildCount() == 0)
                    viewAnimator.showMenuContent();
            }

            /** Called when a drawer has settled in a completely open state. */
            public void onDrawerOpened(View drawerView) {

            default:
                return super.onOptionsItemSelected(item);
        }
    }

    private ScreenShotable replaceFragment(ScreenShotable screenShotable, int topPosition) {
        //get the top position. it generates unique link according to the clicked view
        this.res = this.res == R.drawable.content_music ? R.drawable.content_films : R.drawable.content_music;
        View view = findViewById(R.id.content_frame);
        int finalRadius = Math.max(view.getWidth(), view.getHeight());
        SupportAnimator animator = ViewAnimationUtils.createCircularReveal(view, 0, topPosition, 0, finalRadius);
        animator.setInterpolator(new AccelerateInterpolator());
        animator.setDuration(ViewAnimator.CIRCULAR_REVEAL_ANIMATION_DURATION);

而不是使用你需要的活动碎片，而不是它们的意思。
