Android 多窗口启动器侧边栏

问题描述

我希望这个 drawerLayout（波纹管照片）总是像三星多窗口侧边栏一样打开。

直到现在我可以在应用程序中打开这个 drawerLayout(sidebar)。请给出能够从任何地方（我的意思是从任何其他应用程序甚至从设备的主屏幕）打开此 draweLayout（侧边栏）的说明。

提前致谢。

这是我的drayerLayout XML 文件：

解决方法

这不能通过在每个活动中做一些修改来实现全局性

您可以创建一个新类，该类将具有初始化导航的方法，将导航视图移动到单独的 xml 文件并将该文件包含在每个活动中，并在每个活动中调用初始化方法

您可以尝试使用此库 https://github.com/mikepenz/MaterialDrawer 将大多数 xml 代码移至 java，这样您就不必在每个活动中添加 DrawerLayout，但您可以自行选择，如果可以，最好跳过使用 3rd 方库

如果您使用的是图书馆，那么您可以按照以下示例进行操作

常量.java

private void setupNavigationDrawer() {
    ProfileDrawerItem section = new ProfileDrawerItem()
            .withSetSelected(false)
            .withSetSelected(false)
            .withEnabled(false);
    PrimaryDrawerItem joyType0DrawerItem = new PrimaryDrawerItem().withName("Basic Gamepad").withTag(KEY_BASIC_GAMEPAD_1).withLevel(2);
    PrimaryDrawerItem joyType1DrawerItem = new PrimaryDrawerItem().withName("Assault Horizon").withTag(KEY_ASSAULT_HORIZON).withLevel(2);
    PrimaryDrawerItem joyType2DrawerItem = new PrimaryDrawerItem().withName("Awesomenauts").withTag(KEY_AWESOMENAUTS).withLevel(2);
    PrimaryDrawerItem joyType3DrawerItem = new PrimaryDrawerItem().withName("BombSquad").withTag(KEY_BOMBSQUAD).withLevel(2);
    PrimaryDrawerItem joyType4DrawerItem = new PrimaryDrawerItem().withName("Final Fantasy XIII").withTag(KEY_FINAL_FANTASY_XIII).withLevel(2);
    SectionDrawerItem sectionDrawerItem = new SectionDrawerItem().withName("Joystick Type").withTextColorRes(R.color.colorAccent);
    PrimaryDrawerItem deviceDrawerItem = new PrimaryDrawerItem().withName("Device Connection").withTag(KEY_DEVICE_CONNECTION).withIcon(GoogleMaterial.Icon.gmd_devices);
    PrimaryDrawerItem settingsDrawerItem = new PrimaryDrawerItem().withName("Settings").withTag("settings").withIcon(GoogleMaterial.Icon.gmd_settings);

    ndMenu = new DrawerBuilder()
            .withActivity(this)
            .withToolbar(tbMain)
            .withCloseOnClick(true)
            .withFireOnInitialOnClick(true)
            .withSelectedItemByPosition(6)
            .withDelayDrawerClickEvent(300)
            .withDisplayBelowStatusBar(true)
            .withTranslucentStatusBar(false)
            .withOnDrawerItemClickListener(this)
            .addDrawerItems(section,deviceDrawerItem,settingsDrawerItem,sectionDrawerItem,joyType0DrawerItem,joyType1DrawerItem,joyType2DrawerItem,joyType3DrawerItem,joyType4DrawerItem)
            .build();

    findViewById(R.id.nav_button).setOnClickListener(new 
     View.OnClickListener() {
                        @Override
                        public void onClick(View v) {
        // Check these functions from library example to check drawer state and open close drawer
        if(ndMenu.isDrawerOpen){
           ndMenu.closeDrawer();
         } else {
           ndMenu.openDrawer();
         }
        });
}
