Qt6.4获取qml安卓手机路径

在Qt6.4中获取安卓手机路径的方法与Qt5.x有所不同。以下是获取安卓手机路径的步骤：

1. 引入Qt Android Extras模块。

import QtAndroid.Extras 1.0

2. 添加以下权限到AndroidManifest.xml文件中：

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

3. 在C++代码中定义一个槽函数，并使用Qt Android Extras模块中的QAndroidJniObject类获取相册路径。例如：

void MyObject::getAlbumPath(){
    QAndroidJniObject ACTION_PICK = QAndroidJniObject::fromString("android.intent.action.PICK");
    QAndroidJniObject externalContentUri = QAndroidJniObject::fromString("content://media/external/images/media");
    QAndroidJniObject intent("android/content/Intent", "(Ljava/lang/String;Landroid/net/Uri;)V", ACTION_PICK.object<jstring>(), externalContentUri.object<jobject>());
    QtAndroid::startActivity(intent, 101, [this](int requestCode, const QAndroidJniObject& data){
        if(requestCode == 101){
            QAndroidJniObject uri = data.callObjectMethod("getData", "()Landroid/net/Uri;");
            QAndroidJniObject filePath = QAndroidJniObject::callStaticObjectMethod("android/os/Environment", "getExternalStorageDirectory", "()Ljava/io/File;");
            filePath = filePath.callObjectMethod("getAbsolutePath", "()Ljava/lang/String;");
            QAndroidJniObject resolver = QtAndroid::androidActivity().callObjectMethod("getContentResolver","()Landroid/content/ContentResolver;");
            QAndroidJniObject options;
            options = QAndroidJniObject::callStaticObjectMethod("android/provider/MediaStore$Images$Media", "query", "(Landroid/content/ContentResolver;Landroid/net/Uri;[Ljava/lang/String;Ljava/lang/String;[Ljava/lang/String;)Landroid/database/Cursor;", resolver.object<jobject>(), uri.object<jobject>(), nullptr, nullptr, nullptr);
            jint columnIndex = options.callMethod<jint>("getColumnIndex", "(Ljava/lang/String;)I", QAndroidJniObject::fromString("_data").object<jstring>());
            options.callMethod<jboolean>("moveToFirst");
            QAndroidJniObject path = options.callObjectMethod("getString", "(I)Ljava/lang/String;", columnIndex);
            qDebug() << "Path: " << path.toString();
        }
    });
}

该函数会弹出相册选择界面，用户选择一张图片后，会返回该图片的路径。需要注意的是，该函数只能在Qt Android应用程序中调用，不能在Windows、Linux等平台下测试运行。

以上就是在Qt6.4中获取安卓手机路径的方法。
