无法使用WindowManager.LayoutParams.FLAG_KEEP_SCREEN_ON创建QAndroidJniObject对象

Question

下面是我的代码，试图创建一个QAndroidJniObject来访问在……上面值。

所以我就这么做：

QAndroidJniObject activity = QAndroidJniObject::callStaticObjectMethod("org/qtproject/qt5/android/QtNative", "activity", "()Landroid/app/Activity;");
if ( activity.isValid() )
{
    jint keepAliveField = QAndroidJniObject::getStaticField<jint>("android/view/WindowManager/LayoutParams","FLAG_KEEP_SCREEN_ON");

    qDebug() << "keepAliveField=" << keepAliveField;
}

知道为什么当我期待keepAliveField=0的时候，它会打印keepAliveField=128

Answer 1

类是WindowManager.LayoutParams，只需替换'.‘加上“$”

QAndroidJniObject::getStaticField<jint>(
            "android/view/WindowManager$LayoutParams", "FLAG_KEEP_SCREEN_ON");
