Question

使用活动结果裁剪图像时出现问题。我已在设备＆gt; 6上设置了权限。但是当显示裁剪和裁剪成功时，结果数据为空。（imageReturnedIntent.getData() us null和intent数据也为null）。它是代码裁剪图像。

public static Intent cropIntent(Uri inUri, int outputX, int outputY,
                                    boolean isScale) {
        Intent cropIntent = new Intent("com.android.camera.action.CROP");
        cropIntent.setDataAndType(inUri, "image/*");
        cropIntent.putExtra("crop", "true");
        cropIntent.putExtra("aspectX", outputX > 0 ? outputX : 100);
        cropIntent.putExtra("aspectY", outputY > 0 ? outputY : 100);
        cropIntent.putExtra("outputX", outputX > 0 ? outputX : 100);
        cropIntent.putExtra("outputY", outputY > 0 ? outputY : 100);
        cropIntent.putExtra("scale", isScale);
        File file = new File(Environment.getExternalStorageDirectory() + File.separator + "img.jpg");
        Uri mCropImagedUri = Uri.fromFile(file);
        cropIntent.putExtra(android.provider.MediaStore.EXTRA_OUTPUT, mCropImagedUri);
        cropIntent.putExtra("return-data", true);
        return cropIntent;
    }

是代码活动

 @Override
    protected void onActivityResult(int requestCode, int resultCode, Intent imageReturnedIntent) {
        super.onActivityResult(requestCode, resultCode, imageReturnedIntent);
        if (callbackManager != null) {
            callbackManager.onActivityResult(requestCode, resultCode, imageReturnedIntent);

        }

        switch (requestCode) {
            case SELECT_PHOTO:
                if (resultCode == RESULT_OK) {

                    Uri uriImage = imageReturnedIntent.getData();
                    System.out.println(">>>> uri "+uriImage);
                 //   CommonUtils.cropImage(uriImage,HomeActivity.this,SELECT_CROP_IMAGE);
                    startActivityForResult(CommonUtils.cropIntent(uriImage,
                            200, 200, true), SELECT_CROP_IMAGE);
                }
                break;
            case SELECT_CROP_IMAGE:
                if (resultCode == RESULT_OK) {
                 //   Uri uri = imageReturnedIntent.getData();

                    System.out.println(">>>>> "+imageReturnedIntent.getData());
                    Bundle extras = imageReturnedIntent.getExtras();
                    if (extras == null) {
                        System.out.println(">>>>> check intent");
                        return;
                    }
                  // Bitmap bitMapScale = extras.getParcelable("data");
                    Uri uri = extras.getParcelable(MediaStore.EXTRA_OUTPUT);
                    try {
                        Bitmap bitMapScale = MediaStore.Images.Media.getBitmap(this.getContentResolver(), uri);
                        System.out.println(">>>>>> check " + bitMapScale);
                        //       yourSelectedImage.recycle();
                        // base64
                        String myBase64Image = CommonUtils.encodeToBase64(bitMapScale, Bitmap.CompressFormat.PNG, 100);
                        //   bitMapScale.recycle();
                        assert uri != null;
                        LocalStorage.getShareInstance().saveUriAvatar(uri.toString());
                        LocalStorage.getShareInstance().saveBase64Image(myBase64Image);
                        UserModel userModel = LocalStorage.getShareInstance().getUserLogin();
                        if (userModel == null) {
                            // if user have not login.
                            if (uiLeftMenu != null) {
                                uiLeftMenu.fillImage(uri);
                            }
                        } else {
                            System.out.println(">>>>>> check data");
                            if (CommonUtils.isStringDataValid(myBase64Image)) {

                                upLoadImageToServerWithStringBase64(myBase64Image);
                            }
                        }
                    } catch (IOException e) {
                        e.printStackTrace();
                    }


                }
                break;
        }
    }

有什么问题？

我在Huwai设备上也遇到了同样的问题。某些设备未通过intent.getData()发送目的地Uri。但经过一些调试后，我发现uri设置在mAction字符串变量上，可以通过intent.getAction()方法访问它。然后你可以使用'Uri.parse（outPutFilePath）'这个方法生成Uri。您可以先检查intent.getData()是否为空。如果为null，则使用intent.getAction()方法将Uri作为字符串并生成输出Uri。我这样解决了我的问题。希望这会有所帮助。
