Question

我试图显示一个对话框，在其中按下ImageButton的位置，然后从图库中选择图片或从相机中获取图片。我已经在努力选择图像并将其插入正确的图像视图中。

现在，单击ImageButton（android：id =“ @ + id / imageSelect”）将弹出对话框，然后从图库中选择，但它将图像插入（android：id =“ @ + id / imageSelect1）应该插入（android：id =“ @ + id / imageSelect）。当我选择（android：id =“ @ + id / imageSelect1）时，它只会覆盖图像，因此（android：id =” @ + id / imageSelect1）保持为空

我觉得SelectPhotoDialog类有问题。

在没有对话框的情况下也可以正常工作，但是我希望可以从相机或图库中选择该选项。

这是我的xml文件：

IniversalImageLoader文件

Universal image loader

Answer 1

我不确定，但是我认为没有足够的信息...我找不到所引用的UniversalImageLoader，我想它可以处理图像的实际设置，因为setImage暗示。

@Override

    public void getImagePath(Uri imagePath) {

        Log.d(TAG, "getImagePath: setting the image to imageview");

       // THIS LINE  UniversalImageLoader.setImage(imagePath.toString(), mSelectImage);

 

        //assign to global variable

        mSelectedBitmap = null;

        mSelectedUri = imagePath;

    }

更新为答案
好的，这就是我通常执行的对话框

private static final int READ_REQUEST_CODE = 42;

public void performFileSearch()
{

    // ACTION_OPEN_DOCUMENT is the intent to choose a file via the system's file
    // browser.
    Intent intent = new Intent(Intent.ACTION_OPEN_DOCUMENT);

    // Filter to only show results that can be "opened", such as a
    // file (as opposed to a list of contacts or timezones)
    intent.addCategory(Intent.CATEGORY_OPENABLE);

    // Filter to show only images, using the image MIME data type.
    // If one wanted to search for ogg vorbis files, the type would be "audio/ogg".
    // To search for all documents available via installed storage providers,
    // it would be "*/*".
    intent.setType("*/*");

    startActivityForResult(intent, READ_REQUEST_CODE);
}
@Override
public void onActivityResult(int requestCode, int resultCode,
                             Intent resultData)
{
   if (requestCode == READ_REQUEST_CODE && resultCode == Activity.RESULT_OK)
    {
       Uri uri = null;
        if (resultData != null)
        {
            uri = resultData.getData();
            String back = uri.toString();
           // DO SOMETHING WITH STRING
        }
    }
}

这样您的代码就可以了

    @Nullable
@Override
public View onCreateView(LayoutInflater inflater, @Nullable ViewGroup container, @Nullable Bundle savedInstanceState) {
    View view = inflater.inflate(R.layout.dialog_selectphoto, container, false);

    TextView selectPhoto = (TextView) view.findViewById(R.id.dialogChoosePhoto);
    selectPhoto.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View v) {
            Log.d(TAG, "onClick: accessing phones memory.");
            performFileSearch()
        }
    });

    TextView selectPhoto1 = (TextView) view.findViewById(R.id.dialogChoosePhoto1);

    selectPhoto1.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View v) {
            Log.d(TAG, "onClick: accessing phones memory.");
            performFileSearch();
        }
    });

    TextView takePhoto = (TextView) view.findViewById(R.id.dialogOpenCamera);
    takePhoto.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View v) {
            Log.d(TAG, "onClick: starting camera.");
            Intent intent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);
            startActivityForResult(intent, CAMERA_REQUEST_CODE);

        }
    });
    return view;
}

//我不认为这是原因，仅是因为一切似乎一直流到设置图像的那一部分...对话框将uri返回到图像，但是另一个代码正在设置图像在错误的位置，

ImageView X = (ImageView) findViewById(R.id.ImageViewID); 
X.setBackgroundResource ?

我正在寻找类似的东西，我认为这可能是导致问题的原因。

抓取
我找到了ImageLoader，一切似乎都很好..

Constructor Detail:

ImageLoader

public ImageLoader(RequestQueue queue, ImageLoader.ImageCache imageCache)Constructs a new ImageLoader.

// Parameters:queue - The RequestQueue to use for making image requests.imageCache - The cache to use as an L1 cache.

您是否尝试过另一种设置图像的方式？
