Android 全屏显示、禁用下拉通知消息栏、上拉虚拟按钮栏...

禁用下拉拉出消息通知栏，禁用上拉拉出虚拟按键栏

一种是直接使用statusBarManager

此例用kotlin来写
方法网上都有，有几个错误点要注意
要引入系统的framework.jar或者在系统源码中编译，不然会编译出错
Unresolved reference: DISABLE_EXPAND

 private var statusBarManager: StatusBarManager = context.getSystemService("statusbar") as StatusBarManager
 
 // 禁用
 statusBarManager.disable(StatusBarManager.DISABLE_EXPAND)
 // 还原
 statusBarManager.disable(StatusBarManager.DISABLE_NONE)

要加上权限

    <!-- status bar -->
    <uses-permission android:name="android.permission.EXPAND_STATUS_BAR"/>
    <uses-permission android:name="android.permission.STATUS_BAR" 
                     tools:ignore="ProtectedPermissions" /> <!--状态栏修改-->

否则会出错

java.lang.SecurityException: StatusBarManagerService: Neither user 10167 nor current process has android.permission.STATUS_BAR.

另一种用反射的方法来做

此例用java来写

/**
 * 用反射实现控制StatusBar状态，需要是system应用
 */
public class StatusBarUtil {
    public static final int STATUS_BAR_DISABLE_HOME = 0x00200000;
    public static final int STATUS_BAR_DISABLE_RECENT = 0x01000000;
    public static final int STATUS_BAR_DISABLE_BACK = 0x00400000;
    public static final int STATUS_BAR_DISABLE_EXPAND = 0x00010000;
    public static final int STATUS_BAR_DISABLE_NONE = 0x00000000;

    public static void setStatusBarState(Context context, int disableFlag) {
        @SuppressLint("WrongConstant") Object service = context.getSystemService("statusbar");
        try {
            Class<?> statusbarManager = Class.forName("android.app.StatusBarManager");
            Method disable = statusbarManager.getMethod("disable", int.class);
            disable.invoke(service, disableFlag);
        } catch (Exception e) {
            e.printStackTrace();
        }
    }

    /**
     * 禁用顶部状态栏的下拉及底部虚拟的回退等按键
     */
    public static void disableStatusBar(Context context) {
        // Disable *all* possible navigation via the system bar.
        int state = STATUS_BAR_DISABLE_EXPAND | STATUS_BAR_DISABLE_HOME | STATUS_BAR_DISABLE_RECENT | STATUS_BAR_DISABLE_BACK;
        setStatusBarState(context, state);
    }

    public static void enableStatusBar(Context context) {
        setStatusBarState(context, STATUS_BAR_DISABLE_NONE);
    }

}

全屏显示

单纯地禁用上下拉，不能满屏显示，虚拟键盘显示的地方会是全黑无法显示，还需要额外的操作

    //在Ui中调用此函数，确保满屏隐藏虚拟键盘
    public void makeWindowFullScreen() {
        this.getWindow().setFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN,
                WindowManager.LayoutParams.FLAG_FULLSCREEN);
        getWindow().getDecorView().setSystemUiVisibility(View.SYSTEM_UI_FLAG_HIDE_NAVIGATION
                | View.SYSTEM_UI_FLAG_LAYOUT_HIDE_NAVIGATION
                | View.SYSTEM_UI_FLAG_LAYOUT_FULLSCREEN
                | View.SYSTEM_UI_FLAG_LAYOUT_STABLE
                | View.SYSTEM_UI_FLAG_FULLSCREEN
                | View.SYSTEM_UI_FLAG_IMMERSIVE_STICKY
        );
    }
