我有一个应用程序，我可以让用户选择画廊图像或用相机拍照，然后我给他裁剪它的选项。

现在，当用户裁剪图像时，Gallery 裁剪器返回裁剪部分的 ByteArray，是否可以传递一个参数要求 Gallery 裁剪器将输出保存到文件（就像我开始意图在摄像头）

例如：

这是我使用的裁剪代码：

// Initialize intent
Intent intent = new Intent("com.android.camera.action.CROP");
// set data type to be sent
intent.setType("image/*");

// get croppers available in the phone
List<ResolveInfo> list = getPackageManager().queryIntentActivities( intent, 0 );
int size = list.size();
// handle the case if there's no cropper in the phone
if (size == 0) {
    Toast.makeText(this, "Can not find image crop app", Toast.LENGTH_SHORT).show();
    return;
} else {

// now this is the case if cropper exists
// initialize the Uri for the captures or gallery image

    Uri imageUri = Uri.fromFile(new File(mCurrentPhotoPath));

    // Send the Uri path to the cropper intent
    intent.setData(imageUri); 
    intent.putExtra("outputX", 200);
    intent.putExtra("outputY", 200);
    intent.putExtra("aspectX", 1);
    intent.putExtra("aspectY", 1);         
    intent.putExtra("scale", true);
    // Here's my attempt to ask the intent to save output data as file
    File f = null;
    // Here I initialize empty file 
    try{
            // This returns the file created
        f = setUpCroppedFile();
        mCurrentThumbPath = f.getAbsolutePath();            
        intent.putExtra(MediaStore.EXTRA_OUTPUT, Uri.fromFile(f));            
        intent.putExtra("output", Uri.fromFile(f));         
    }
    catch(IOException e){
        e.printStackTrace();
    }
    // --------------------------------------------------------------------
    // -----------> When changing this to false it worked <----------------
    // --------------------------------------------------------------------        
    intent.putExtra("return-data", true);
    // --------------------------------------------------------------------
    // --------------------------------------------------------------------

    // If there's only 1 Cropper in the phone (e.g. Gallery )
    if (size == 1) {
            // get the cropper intent found
            Intent i        = new Intent(intent);
            ResolveInfo res = list.get(0);

            i.setComponent( new ComponentName(res.activityInfo.packageName, res.activityInfo.name));

            startActivityForResult(i, CROPPED_PHOTO);
    }

   // Please ignore the case if there are more . . I know how to handle it

更新：问题已解决，我想我会把它留在这里，以防其他人发现它有用（请参阅上面代码中的大注释）

此代码是修改后的代码，它可以工作：

// Initialize intent
Intent intent = new Intent("com.android.camera.action.CROP");
// set data type to be sent
intent.setType("image/*");

// get croppers available in the phone
List<ResolveInfo> list = getPackageManager().queryIntentActivities( intent, 0 );
int size = list.size();
// handle the case if there's no cropper in the phone
if (size == 0) {
    Toast.makeText(this, "Can not find image crop app", Toast.LENGTH_SHORT).show();
    return;
} else {

// now this is the case if cropper exists
// initialize the Uri for the captures or gallery image

    Uri imageUri = Uri.fromFile(new File(mCurrentPhotoPath));

    // Send the Uri path to the cropper intent
    intent.setData(imageUri); 
    intent.putExtra("outputX", 200);
    intent.putExtra("outputY", 200);
    intent.putExtra("aspectX", 1);
    intent.putExtra("aspectY", 1);         
    intent.putExtra("scale", true);
    // Here's my attempt to ask the intent to save output data as file
    File f = null;
    // Here I initialize empty file 
    try{
            // This returns the file created
        f = setUpCroppedFile();
        mCurrentThumbPath = f.getAbsolutePath();            
        intent.putExtra(MediaStore.EXTRA_OUTPUT, Uri.fromFile(f));            
        intent.putExtra("output", Uri.fromFile(f));         
    }
    catch(IOException e){
        e.printStackTrace();
    }
    // --------------------------------------------------------------------
    // -----------> When changing this to false it worked <----------------
    // --------------------------------------------------------------------        
    intent.putExtra("return-data", false);
    // --------------------------------------------------------------------
    // --------------------------------------------------------------------

    // If there's only 1 Cropper in the phone (e.g. Gallery )
    if (size == 1) {
            // get the cropper intent found
            Intent i        = new Intent(intent);
            ResolveInfo res = list.get(0);

            i.setComponent( new ComponentName(res.activityInfo.packageName, res.activityInfo.name));

            startActivityForResult(i, CROPPED_PHOTO);
    }
