android - 如何让我的应用程序在华为 Mate 10 Pro 或其他 18 :9 ratio phones? 上全屏显示

Question

我试过像这样在我的样式中强制“全屏”:

<item name="android:windowNoTitle">true</item>
<item name="android:windowFullscreen">true</item>

我从我的 Activity 中尝试过:

getWindow().addFlags(WindowManager.LayoutParams.FLAG_LAYOUT_IN_SCREEN);
getWindow().addFlags(WindowManager.LayoutParams.FLAG_LAYOUT_NO_LIMITS);

我什至尝试过这个，当我按下“全屏显示”按钮时，它会调用 Intent :

public static boolean goToFullScreen(final Activity activity) {
    PackageManager packageManager = activity.getPackageManager();
    try {
        if ("huawei".equalsIgnoreCase(android.os.Build.MANUFACTURER)) {
            final Intent huaweiIntent = new Intent();
            huaweiIntent.setComponent(new ComponentName("com.android.systemui", "com.android.systemui.settings.HwChangeButtonActivity"));
            if (huaweiIntent.resolveActivity(packageManager) != null) {
                activity.startActivity(huaweiIntent);
                return true;
            }
        }
    } catch (Exception e) {
        Utils.appendLog("goToBatterySettings exception:" + e.getMessage(), "E", Constants.OTHER);
    }
    return false;
}

但我总是得到这个Screenshot

知道如何解决这个问题吗？

将以下内容添加到 <application>元素:

<meta-data android:name="android.max_aspect" android:value="2.1" />
