Question

当我们使用uri添加mediastore.EXTRA_OUTPUT时，我知道intent数据为null。仅在返回图像的缩略图时它不为空。但是我有3个imageViews，用户可以点击它们点击图片。单击的图片必须显示在该特定的imageView上。

@Override
    public void onClick(View v) {
        switch (v.getId()){
            case R.id.iv_rx1:
                Toast.makeText(mContext, "Clicked", Toast.LENGTH_LONG).show();
                break;

            case R.id.iv_rx2:
                File f2 = getOutputMediaFile();
                Uri uri2 = Uri.fromFile(f2);
                selectImage(uri2);
                Toast.makeText(mContext, "Clicked", Toast.LENGTH_LONG).show();
                break;

            case R.id.iv_rx3:
                File f3 = getOutputMediaFile();
                Uri uri3 = Uri.fromFile(f3);
                selectImage(uri3);
                Toast.makeText(mContext, "Clicked", Toast.LENGTH_LONG).show();
                break;

            case R.id.iv_rx4:
                File f4 = getOutputMediaFile();
                Uri uri4 = Uri.fromFile(f4);
                selectImage(uri4);
                Toast.makeText(mContext, "Clicked", Toast.LENGTH_LONG).show();
                break;
        }
    }

    private void selectImage(Uri uri) {
        final CharSequence[] items = {"Take Photo", "Choose from Library",
                "Cancel"};
        final Uri uri1=uri;
        AlertDialog.Builder builder = new AlertDialog.Builder(mContext);
        builder.setTitle("Add picture of Prescription");
        builder.setItems(items, new DialogInterface.OnClickListener() {
            @Override
            public void onClick(DialogInterface dialog, int item) {
                if (items[item].equals("Take Photo")) {
                    Intent intent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);
                    intent.putExtra(MediaStore.EXTRA_OUTPUT, uri1);
                    intent.putExtra(PRESCRIPTION_URI_INTENT, uri1.getPath());
                    Log.d("URI VALUE", uri1.getPath());
                    startActivityForResult(intent, Constants.REQUEST_IMAGE_CAPTURE);
                }

The on Activity Result for the same

     @Override
        public void onActivityResult(int requestCode, int resultCode, Intent data) {
            super.onActivityResult(requestCode, resultCode, data);
            if (resultCode == Activity.RESULT_OK) {
                switch (requestCode) {
                    case Constants.REQUEST_IMAGE_CAPTURE:
                        //String locationImage= intent.getStringExtra(PRESCRIPTION_URI_INTENT);

                        Bitmap bitmap = BitmapFactory.decodeFile(imageLocation);
                        imageView.setBitmap(bitmap);
                        //Want to change the image view to which bitmap must be added based on which image view the user clicks on
                        break;

                    case Constants.REQUEST_GALLERY:
                        Uri selectedImageUri = data.getData();
                        Intent galleryIntent = new Intent(mContext, newConfirmPrescriptionAct.class);
                        galleryIntent.putExtra(IMAGE_PATH_AS_STRING, selectedImageUri.toString());
                        galleryIntent.putExtra(Constants.IMAGE_SOURCE_TYPE, Constants.REQUEST_GALLERY);                        
                        galleryIntent.putExtra(DOES_CONTAIN_ONLY_OTC, false);
                        startActivity(galleryIntent);
                        break;
                }//Close switch statement

            } else {
                Log.d("Error ", "user canceled !");
            }
        } //Continues for some other options (not to do with the camera)

其中String imageLocation = uri1.getPath()包含保存图像的路径。

我可以点击图片并将其添加到一个图片视图，但不知道如何修改它以处理不同图像视图上的多次点击。我想到的一个解决方案是更改request code并添加有关使用哪个视图的信息并添加相关的switch语句。有没有其他方法可以这样做？

将其他数据传递给onActivityResult（用相机拍照）
