android - 使用 QT 打开位置设置 Android

Question

如何通过 Qt 从 android 打开位置设置？

我已经试过了，可以成功打开设置，但是不能打开位置设置:

QAndroidJniObject intent("android/content/Intent","()V");
    if ( intent.isValid() )
    {
        QAndroidJniObject param1 = QAndroidJniObject::fromString("com.android.settings");
        QAndroidJniObject param2 = QAndroidJniObject::fromString("com.android.settings.Settings");

        if ( param1.isValid() && param2.isValid() )
        {
            intent.callObjectMethod("setClassName","(Ljava/lang/String;Ljava/lang/String;)Landroid/content/Intent;",param1.object<jobject>(),param2.object<jobject>());

            activity.callObjectMethod("startActivity","(Landroid/content/Intent;)V",intent.object<jobject>());
        }
    }

我什至将 param2 更改为“android.settings.LOCATION_SOURCE_SETTINGS”，因为它写在 Android 开发者页面上 - 但没有任何成功。

有人知道怎么做吗？ 谢谢!

我找到了解决办法!

QAndroidJniObject activity = QAndroidJniObject::callStaticObjectMethod("org/qtproject/qt5/android/QtNative", "activity", "()Landroid/app/Activity;");
if ( activity.isValid() )
{
    qDebug() << "activity.isValid()";
    QAndroidJniObject param = QAndroidJniObject::fromString("android.settings.LOCATION_SOURCE_SETTINGS");

    if (param.isValid() )
    {
        QAndroidJniObject intent("android/content/Intent","(Ljava/lang/String;)V", param.object<jstring>());
        activity.callObjectMethod("startActivity","(Landroid/content/Intent;)V",intent.object<jobject>());
    }
}
