使用Game Maker Studio中的Java Extension为Android选择图像

Question

我正在尝试为Game Maker Studio Android应用制作Java扩展。

我曾尝试使用在线教程中的代码，但GMS使用了不同的方法，因此无法正常工作。

我正在使用以下代码：

package ${YYAndroidPackageName};

//Basic imports
import android.util.Log;
import java.lang.String;
import java.lang.String;

import android.app.Activity;
import android.content.Intent;
import java.net.MalformedURLException;
import java.net.URI;
import java.net.URISyntaxException;
import java.net.URL;

//Import Game Maker classes
import ${YYAndroidPackageName}.R;
import com.yoyogames.runner.RunnerJNILib;
import ${YYAndroidPackageName}.RunnerActivity;

public class pickimage extends Activity {

    public static final int PICK_IMAGE = 1;
    private static final int EVENT_OTHER_SOCIAL = 70;

    public void selectimage() 
    {
        Intent intent = new Intent();
        intent.setType("image/*");
        intent.setAction(Intent.ACTION_GET_CONTENT);
        startActivityForResult(Intent.createChooser(intent, "Select Picture"), PICK_IMAGE);
        int dsMapIndex = RunnerJNILib.jCreateDsMap(null, null, null);
        RunnerJNILib.DsMapAddString( dsMapIndex, "type", "pickeropened" );
        RunnerJNILib.DsMapAddDouble( dsMapIndex, "argument0", 2);
        RunnerJNILib.DsMapAddDouble( dsMapIndex, "argument0", 3);
        RunnerJNILib.CreateAsynEventWithDSMap(dsMapIndex, EVENT_OTHER_SOCIAL);
    }

    public void onActivityResult(int requestCode, int resultCode, Intent data) {
        URI selectedImageUri = null;
        if (resultCode == RESULT_OK) {
            if (requestCode == SELECT_PICTURE) {
                selectedImageUri = new URI(data.getData());
                //String selectedImagePath = getPath(selectedImageUri);
                //Log.i("yoyo", selectedImagePath);
                //return selectedImagePath;
    int dsMapIndex = RunnerJNILib.jCreateDsMap(null, null,null);
    RunnerJNILib.DsMapAddString( dsMapIndex, "type", "imagepath" );
    RunnerJNILib.DsMapAddString( dsMapIndex, "path", selectedImagePath);
    RunnerJNILib.DsMapAddString( dsMapIndex, "path", "boo");
    RunnerJNILib.CreateAsynEventWithDSMap(dsMapIndex, EVENT_OTHER_SOCIAL);
            }
        }
    }

    /**
     * helper to retrieve the path of an image URI

    public String getPath(Uri uri) {
            // just some safety built in 
            if( uri == null ) {
                // TODO perform some logging or show user feedback
                return null;
            }
            // try to retrieve the image from the media store first
            // this will only work for images selected from gallery
            String[] projection = { MediaStore.Images.Media.DATA };
            Cursor cursor = managedQuery(uri, projection, null, null, null);
            if( cursor != null ){
                int column_index = cursor
                .getColumnIndexOrThrow(MediaStore.Images.Media.DATA);
                cursor.moveToFirst();
                return cursor.getString(column_index);
            }
            // this is our fallback here
            return uri.getPath();
    }*/

}

我已经遵循了GMS扩展教程，但是它不起作用。 以下是控制台中的一些错误通知：

  location: class pickimage
Note: Some input files use or override a deprecated API.
* What went wrong:
Execution failed for task ':com.companyname.Test_Image_Chooser:compileReleaseJavaWithJavac'.

我要实现的是用户在应用程序中按下按钮，它会打开“本地图像选择器”对话框，用户选择一个文件。 然后用户按下另一个按钮，应用程序将获取所选图像的完整路径，然后将其上传到服务器。

我是Java新手:)

有人可以帮忙吗？

我在您的java文件中看到了一些问题，使用意图时，您必须通知jnirunner您正在激活意图，并且那里还有一个多余的参数和其他多余的东西，因此这部分代码

startActivityForResult(Intent.createChooser(intent, "Select Picture"), PICK_IMAGE);
int dsMapIndex = RunnerJNILib.jCreateDsMap(null, null, null);
    RunnerJNILib.DsMapAddString( dsMapIndex, "type", "pickeropened" );
    RunnerJNILib.DsMapAddDouble( dsMapIndex, "argument0", 2);
    RunnerJNILib.DsMapAddDouble( dsMapIndex, "argument0", 3);
    RunnerJNILib.CreateAsynEventWithDSMap(dsMapIndex, EVENT_OTHER_SOCIAL);

应该看起来更像这样，并在其之前有一个连接器语句来通知运行器，并且此时不要调用async事件：

RunnerActivity.CurrentActivity.startActivityForResult(intent, PICK_IMAGE);

因此，在onActivityResult代码中，您已经注释掉了代码的重要部分，因此async事件无法获取所需的信息，并且其中还有一些额外的内容，并且您用不同的输出两次声明了“ path”代码行变量，所以这

 public void onActivityResult(int requestCode, int resultCode, Intent data) {
    URI selectedImageUri = null;
    if (resultCode == RESULT_OK) {
        if (requestCode == SELECT_PICTURE) {
            selectedImageUri = new URI(data.getData());
            //String selectedImagePath = getPath(selectedImageUri);
            //Log.i("yoyo", selectedImagePath);
            //return selectedImagePath;
            int dsMapIndex = RunnerJNILib.jCreateDsMap(null, null,null);
            RunnerJNILib.DsMapAddString( dsMapIndex, "type", "imagepath" );
            RunnerJNILib.DsMapAddString( dsMapIndex, "path", selectedImagePath);
            RunnerJNILib.DsMapAddString( dsMapIndex, "path", "boo");
            RunnerJNILib.CreateAsynEventWithDSMap(dsMapIndex, EVENT_OTHER_SOCIAL);
        }
    }
}

应该变成这个

public void onActivityResult(int requestCode, int resultCode, Intent data) {
 super.onActivityResult(int requestCode, int resultCode, Intent data)
    if (resultCode == RESULT_OK) {
        if (requestCode == PICK_IMAGE) {
            String path = data.getData().toString());
            Log.i("yoyo", path);
            int dsMapIndex = RunnerJNILib.jCreateDsMap(null, null,null);
            RunnerJNILib.DsMapAddString( dsMapIndex, "type", "imagepath" );
            RunnerJNILib.DsMapAddString(result, "selectedImageUri", path);
            RunnerJNILib.CreateAsynEventWithDSMap(dsMapIndex, EVENT_OTHER_SOCIAL);
        }
    }
}
