Android导航抽屉片段

Sha

我想创建一个音乐播放器应用程序,其中包含一个由DEFAULT在Android Studio中创建的导航抽屉。我只想显示片段中的内容。例如,媒体控件或歌曲列表需要位于片段中。单击任何导航菜单项后,它必须用完整的操作栏将新的片段替换为旧的片段。但是,我不确定该如何前进。当前,content_main.xml通过activity_main.xml打开。请帮忙 !!activity_main.xml

我已经这样做了,我已经使用了导航视图。根据ID更改您的操作。

NavigationView navigationView = (NavigationView) findViewById(R.id.nav_view);
        if (navigationView != null) {
            setupDrawerContent(navigationView);

    }

    private void setupDrawerContent(NavigationView navigationView) {
        navigationView.setNavigationItemSelectedListener(
                new NavigationView.OnNavigationItemSelectedListener() {
                    @Override
                    public boolean onNavigationItemSelected(MenuItem menuItem) {                            
                        switch (menuItem.getItemId()) {
                            case R.id.action_settings:
                                menuItem.setChecked(true);
                                drawerLayout.closeDrawers();
                                doFragmentTransaction();
                        }
                        return true;
                    }
                });
    }

这是我的工具栏布局

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:orientation="vertical">

    <android.support.v7.widget.Toolbar
        xmlns:android="http://schemas.android.com/apk/res/android"
        android:id="@+id/tool_bar"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:background="@color/primary"
        android:elevation="2dp"
        android:theme="@style/Base.ThemeOverlay.AppCompat.Dark" />


    <FrameLayout
        android:id="@+id/content_frame"
        android:layout_width="match_parent"
        android:background="@android:color/holo_red_dark"
        android:layout_height="match_parent" />

</LinearLayout>

这是我的main.xml

<android.support.v4.widget.DrawerLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:app="http://schemas.android.com/apk/res-auto"
    android:id="@+id/drawer_layout"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:fitsSystemWindows="true">
    <!-- The main content view -->

    <include layout="@layout/toolbar" />


    <!-- The navigation drawer -->

    <android.support.design.widget.NavigationView
        android:id="@+id/nav_view"
        android:layout_width="wrap_content"
        android:layout_height="match_parent"
        android:layout_gravity="start"
        android:fitsSystemWindows="true"
        app:headerLayout="@layout/nav_header"
        app:menu="@menu/menu_main" />


</android.support.v4.widget.DrawerLayout>
