Question

我正在尝试通过ABBYY Cloud OCR示例代码的主要活动中的库嵌入剪切器。但无论我如何努力，而不是执行裁剪代码，它总是跳到下一个活动。为什么会这样？

package bahadur.translateit;

import abbyy.ocrsdk.android.R;
import android.os.Bundle;
import android.app.Activity;
import android.view.Menu;
import android.net.*;

 import eu.janmuller.android.simplecropimage.CropImage;
import android.os.Environment;
import android.provider.MediaStore;
import android.content.Intent;
import android.database.Cursor;
import android.view.View;

public class MainActivity extends Activity {

private final int TAKE_PICTURE = 0;
private final int SELECT_FILE = 1; 

private String resultUrl = "result.txt";

@Override
public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);
}

@Override
public boolean onCreateOptionsMenu(Menu menu) {
    getMenuInflater().inflate(R.menu.activity_main, menu);
    return true;
}


public void captureImageFromSdCard( View view ) {
    Intent intent = new Intent(Intent.ACTION_GET_CONTENT);
    intent.setType("image/*");

    startActivityForResult(intent, SELECT_FILE);
}

public static final int MEDIA_TYPE_IMAGE = 1;

private static Uri getOutputMediaFileUri(){
      return Uri.fromFile(getOutputMediaFile());
}

/** Create a File for saving an image or video */
private static File getOutputMediaFile(){
    // To be safe, you should check that the SDCard is mounted
    // using Environment.getExternalStorageState() before doing this.

    File mediaStorageDir = new File(Environment.getExternalStoragePublicDirectory(
              Environment.DIRECTORY_PICTURES), "TranlateIt!");
    // This location works best if you want the created images to be shared
    // between applications and persist after your app has been uninstalled.

    // Create the storage directory if it does not exist
    if (! mediaStorageDir.exists()){
        if (! mediaStorageDir.mkdirs()){
            return null;
        }
    }

    // Create a media file name
    File mediaFile = new File(mediaStorageDir.getPath() + File.separator + "image.jpg" );

    return mediaFile;
}

public void captureImageFromCamera( View view) {
    Intent intent = new Intent("android.media.action.IMAGE_CAPTURE");
    Uri fileUri = getOutputMediaFileUri(); // create a file to save the image
    intent.putExtra(MediaStore.EXTRA_OUTPUT, fileUri); // set the image file name

    startActivityForResult(intent, TAKE_PICTURE);
} 

@Override
public void onActivityResult(int requestCode, int resultCode, Intent data) {
    super.onActivityResult(requestCode, resultCode, data);
    if (resultCode != Activity.RESULT_OK)
        return;

    String imageFilePath = null;

    switch (requestCode) {
    case TAKE_PICTURE:
        imageFilePath = getOutputMediaFileUri().getPath();

//下面的裁剪代码无法执行

        Intent intent = new Intent(this, CropImage.class);
        intent.putExtra(CropImage.IMAGE_PATH, imageFilePath);
        intent.putExtra(CropImage.SCALE, true);

        intent.putExtra("outputX", 200); //Set this to define the max size of the output bitmap
        intent.putExtra("outputY", 150); //Set this to define the max size of the output bitmap
        intent.putExtra(CropImage.ASPECT_X, 0);
        intent.putExtra(CropImage.ASPECT_Y, 0);





        break;
    case SELECT_FILE: 
        Uri imageUri = data.getData();

        String[] projection = { MediaStore.Images.Media.DATA };
        Cursor cur = managedQuery(imageUri, projection, null, null, null);
        cur.moveToFirst();
        imageFilePath = cur.getString(cur.getColumnIndex(MediaStore.Images.Media.DATA));

//同样适用于以下代码块

Intent intet = new Intent(this, CropImage.class);
intet.putExtra(CropImage.IMAGE_PATH, imageFilePath);
intet.putExtra(CropImage.SCALE, true);

            intet.putExtra("outputX", 200); //Set this to define the max size of the output bitmap
            intet.putExtra("outputY", 150); //Set this to define the max size of the output bitmap
            intet.putExtra(CropImage.ASPECT_X, 0);
            intet.putExtra(CropImage.ASPECT_Y, 0);



        break;
    }

而不是

    String lastfilepath = imageFilePath;

    //Remove output file
    deleteFile(resultUrl);

    Intent results = new Intent( this, ResultsActivity.class);
    results.putExtra("IMAGE_PATH", lastfilepath);
    results.putExtra("RESULT_PATH", resultUrl);
    startActivity(results);

} 

}

从我的评论中，我的意思是这样的：

case TAKE_PICTURE:
    imageFilePath = getOutputMediaFileUri().getPath();
    Intent intent = new Intent(this, CropImage.class);
    intent.putExtra(CropImage.IMAGE_PATH, imageFilePath);
    intent.putExtra(CropImage.SCALE, true);

    intent.putExtra("outputX", 200); //Set this to define the max size of the output bitmap
    intent.putExtra("outputY", 150); //Set this to define the max size of the output bitmap
    intent.putExtra(CropImage.ASPECT_X, 0);
    intent.putExtra(CropImage.ASPECT_Y, 0);
    startActivity(intent);// THIS is the line you are missing!
