Question

此图像在Oreo版本中不支持编辑。

（此图像不支持编辑）此Toast在Oreo版本移动设备中从图库中选择图像时显示。我已经问过这个问题，但是没人回答我。请检查我的代码，然后尽快还原。

这是我的代码：-

@Override
public void onActivityResult(int requestCode, int resultCode, Intent data) {
    super.onActivityResult(requestCode, resultCode, data);

    if (resultCode != 0) {
        if (requestCode == GALLERY_CAPTURE) {              
            picUri = data.getData();               
            String[] filePathColumn = {MediaStore.Images.Media.DATA};
            Cursor cursor = getContext().getContentResolver().query(picUri, filePathColumn, null, null, null);
            cursor.moveToFirst();
            int columnIndex = cursor.getColumnIndex(filePathColumn[0]);
            String picturePath = cursor.getString(columnIndex);            
            performCrop();
        }            
        else if (requestCode == CROP_PIC) {             
            Bundle extras = data.getExtras();            
            Bitmap thePic = extras.getParcelable("data");
            rimage.setImageBitmap(thePic);
            getCroppedBitmap(thePic);
            Uri tempUri = getImageUri(getActivity(), thePic);
            finalFile = new File(getRealPathFromURI(tempUri));
            Log.e("cropped Image Path", String.valueOf(finalFile));
        }
    }
}

public Uri getImageUri(Context inContext, Bitmap inImage) {
    ByteArrayOutputStream bytes = new ByteArrayOutputStream();
    inImage.compress(Bitmap.CompressFormat.PNG, 100, bytes);
    String path = MediaStore.Images.Media.insertImage(inContext.getContentResolver(), inImage, "Title", null);
    return Uri.parse(path);
}

public String getRealPathFromURI(Uri uri) {
    Cursor cursor = getContext().getContentResolver().query(uri, null, null, null, null);
    cursor.moveToFirst();
    int idx = cursor.getColumnIndex(MediaStore.Images.ImageColumns.DATA);
    return cursor.getString(idx);
}

public Bitmap getCroppedBitmap(Bitmap bitmap) {
    Bitmap output = Bitmap.createBitmap(bitmap.getWidth(),
            bitmap.getHeight(), Bitmap.Config.ARGB_8888);
    Canvas canvas = new Canvas(output);
    final int color = 0xff424242;
    final Paint paint = new Paint();
    final Rect rect = new Rect(0, 0, bitmap.getWidth(), bitmap.getHeight());
    paint.setAntiAlias(true);
    canvas.drawARGB(0, 0, 0, 0);
    paint.setColor(color);
    canvas.drawCircle(bitmap.getWidth() / 2, bitmap.getHeight() / 2,
            bitmap.getWidth() / 2, paint);
    paint.setXfermode(new PorterDuffXfermode(PorterDuff.Mode.SRC_IN));
    canvas.drawBitmap(bitmap, rect, rect, paint);
    return output;
}

private void performCrop() {        
    try {            
        Intent cropIntent = new Intent("com.android.camera.action.CROP");            cropIntent.setClassName("com.prince","com.prince.RegisterStepThree");           
        cropIntent.setDataAndType(picUri, "image/*");         
        cropIntent.putExtra("crop", "true");           
        cropIntent.putExtra("aspectX", 1);
        cropIntent.putExtra("aspectY", 1);            
        cropIntent.putExtra("outputX", 96);
        cropIntent.putExtra("outputY", 96);         
        cropIntent.putExtra("return-data", true);             
        startActivityForResult(cropIntent, CROP_PIC);
    }       
    catch (ActivityNotFoundException anfe) {
        Toast toast = Toast
                .makeText(getContext(), "This device doesn't support the crop action!", Toast.LENGTH_SHORT);
        toast.show();
    }
    catch (Exception e)
    {
        e.printStackTrace();
    }
}

Answer 1

将Uri添加到文件中

intent.putExtra(MediaStore.EXTRA_OUTPUT, Uri.fromFile(<file object>);

我还尝试传递FileProvider.getUriForFile(<file object>)生成的Uri，并且有效。

Answer 2

在包括intent.putExtra(MediaStore.EXTRA_OUTPUT, uri)和ACTION_EDIT在内的多个操作中，使用MediaStore.ACTION_IMAGE_CAPTURE似乎是正确的答案。

请注意，在现代API中，应该使用FileProvider创建URI

Answer 3

这是根据文件路径裁剪图像的代码。我也用 android 11 进行了测试，它工作正常。您还可以在下面的屏幕中看到结果。

在Utils.kt文件中编写的Kotlin函数：

fun performCrop(picUri: File, f: Fragment) {
val packageName: String = f.requireContext().applicationContext.packageName
val authority = "$packageName.fileprovider"

val uri = FileProvider.getUriForFile(f.requireContext(), authority, picUri)
if (Build.VERSION.SDK_INT >= 24) {
    try {
        val m = StrictMode::class.java.getMethod("disableDeathOnFileUriExposure")
        m.invoke(null)
    } catch (e: Exception) {
        e.printStackTrace()
    }
}
try {
    val cropIntent = Intent("com.android.camera.action.CROP")
    cropIntent.setDataAndType(uri, "image/*")
    cropIntent.putExtra("crop", true)
    cropIntent.putExtra("aspectX", 1)
    cropIntent.putExtra("aspectY", 1)
    cropIntent.putExtra("outputX", 512)
    cropIntent.putExtra("outputY", 512)
    cropIntent.putExtra("return-data", true)
    cropIntent.putExtra(MediaStore.EXTRA_OUTPUT, Uri.fromFile(picUri))
    cropIntent.addFlags(Intent.FLAG_GRANT_READ_URI_PERMISSION)
    cropIntent.addFlags(Intent.FLAG_GRANT_WRITE_URI_PERMISSION)
    f.startActivityForResult(
        Intent.createChooser(
            cropIntent,
            "Complete action using"
        ), Constants.REQUEST_CODE_CROP
    )
}
catch (anfe: ActivityNotFoundException) {
    val errorMessage = "Whoops - your device doesn't support the crop action!"
    val toast = Toast.makeText(f.requireContext(), errorMessage, Toast.LENGTH_SHORT)
    toast.show()
} }

从 EditProfile Fragment 调用上述函数：

performCrop(File(editProfileViewModel.filePath), this@EditProfile)

步骤 1：从图库中选择图片

第 2 步：根据需要裁剪图像

步骤 3：在 Imageview 中设置图像

Oreo版本问题中的此图像不支持编辑
