Question

我正在尝试使用以下代码从图库中获取图像：

private void initGalleryFetchImage() {
    Intent i = new Intent(
      Intent.ACTION_PICK,
    android.provider.MediaStore.Images.Media.EXTERNAL_CONTENT_URI);
        startActivityForResult(i, RESULT_LOAD_IMAGE);
}

@Override
public void onActivityResult(int requestCode, int resultCode, Intent data) {
    super.onActivityResult(requestCode, resultCode, data);
    if (requestCode == RESULT_LOAD_IMAGE && resultCode == RESULT_OK && null != data) {
        Uri selectedImage = data.getData();
        String[] filePathColumn = {MediaStore.Images.Media.DATA};

        Cursor cursor = getActivity().getContentResolver().query(selectedImage,
            filePathColumn, null, null, null);
        cursor.moveToFirst();

        int columnIndex = cursor.getColumnIndex(filePathColumn[0]);
        String picturePath = cursor.getString(columnIndex);
        cursor.close();
        LOGI(TAG, "picturePath: " + picturePath);
        if (picturePath.startsWith("http")) {
            Picasso.with(getActivity()).load(picturePath).into(iv);
        } else {
            Picasso.with(getActivity()).load(new File(picturePath)).into(iv);
        }
    }
}

我可以检索除拍摄之外的所有图像并由相机应用程序存储。

有谁知道如何解决这个问题？

Answer 1

onActivityResult（...）中的

使用selectedImage Uri来加载图片

if (picturePath.startsWith("http")) {
      Picasso.with(getActivity()).load(picturePath).into(iv);
} else {
      Picasso.with(getActivity()).load(selectedImage).into(iv);
}

try this


private void initGalleryFetchImage() {
    Intent i = new Intent(
      Intent.ACTION_PICK,
    android.provider.MediaStore.Images.Media.EXTERNAL_CONTENT_URI);
        startActivityForResult(i, RESULT_LOAD_IMAGE);
}

@Override
public void onActivityResult(int requestCode, int resultCode, Intent data) {
    super.onActivityResult(requestCode, resultCode, data);
    if (requestCode == RESULT_LOAD_IMAGE && resultCode == RESULT_OK ) {
Uri selectedImage = data.getData();
                String[] filePathColumn = { MediaStore.Images.Media.DATA };

                try {
                    bmp = BitmapFactory.decodeStream(getContentResolver()
                            .openInputStream(selectedImage));
                } catch (FileNotFoundException e) {
                    // TODO Auto-generated catch block
                    e.printStackTrace();
                }
}}
