android 隐藏虚拟按钮栏及标题等权限设置

华为手机有虚拟按钮，根据以下设置方法可以进行隐藏控制

    /**
     * 隐藏虚拟按键，并且全屏
     */
    protected void hideBottomUIMenu(Context context){
        if(hasNavBar(context)) {
            //隐藏虚拟按键，并且全屏
            if (Build.VERSION.SDK_INT > 11 && Build.VERSION.SDK_INT < 19) { // lower api
                View v = this.getWindow().getDecorView();
                v.setSystemUiVisibility(View.GONE);
            } else if (Build.VERSION.SDK_INT >= 19) {
                //for new api versions.
                View decorView = getWindow().getDecorView();
                int uiOptions = View.SYSTEM_UI_FLAG_LAYOUT_STABLE
                        | View.SYSTEM_UI_FLAG_LAYOUT_HIDE_NAVIGATION
                        | View.SYSTEM_UI_FLAG_LAYOUT_FULLSCREEN
                        | View.SYSTEM_UI_FLAG_HIDE_NAVIGATION // hide nav bar
//                    | View.SYSTEM_UI_FLAG_FULLSCREEN // hide status bar
                        | View.SYSTEM_UI_FLAG_IMMERSIVE;
                decorView.setSystemUiVisibility(uiOptions);
                getWindow().addFlags(WindowManager.LayoutParams.FLAG_TRANSLUCENT_NAVIGATION);
            }
        }
    }

    /**
     * 检查是否存在虚拟按键栏
     * @param context
     * @return
     */
    public static boolean hasNavBar(Context context) {
        Resources res = context.getResources();
        int resourceId = res.getIdentifier("config_showNavigationBar", "bool", "android");
        if (resourceId != 0) {
            boolean hasNav = res.getBoolean(resourceId);
            // check override flag
            String sNavBarOverride = getNavBarOverride();
            if ("1".equals(sNavBarOverride)) {
                hasNav = false;
            } else if ("0".equals(sNavBarOverride)) {
                hasNav = true;
            }
            return hasNav;
        } else { // fallback
            return !ViewConfiguration.get(context).hasPermanentMenuKey();
        }
    }

    /**
     * 判断虚拟按键栏是否重写
     * @return
     */
    private static String getNavBarOverride() {
        String sNavBarOverride = null;
        if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.KITKAT) {
            try {
                Class c = Class.forName("android.os.SystemProperties");
                Method m = c.getDeclaredMethod("get", String.class);
                m.setAccessible(true);
                sNavBarOverride = (String) m.invoke(null, "qemu.hw.mainkeys");
            } catch (Throwable e) {
            }
        }
        return sNavBarOverride;
    }

按钮隐藏前先进行判断手机是否有虚拟按钮，如果不进行判断，在没有虚拟按钮的手机会报错。

 

全屏隐藏标题栏和状态栏的代码为：

getWindow().setFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN,
                WindowManager.LayoutParams.FLAG_FULLSCREEN);

 

设置屏幕持续高亮的代码为：

getWindow().setFlags(WindowManager.LayoutParams.FLAG_KEEP_SCREEN_ON,
                WindowManager.LayoutParams.FLAG_KEEP_SCREEN_ON);

 

AndroidManifest.xml文件权限控制设置如下：

    <uses-permission android:name="android.permission.READ_PHONE_STATE"/>
    <uses-permission android:name="android.permission.ACCESS_WIFI_STATE"/>
