Question

我正在尝试实施一个在图库中选择图片后裁剪图片的活动。我实现了相机拍照，然后它显示裁剪屏幕，我可以保存结果。它显示它没有任何问题。但是当我试图在画廊中选择一张照片时。它说'无法加载'。＆＃39; onResultActivity（）＆＃39;得到resultCode：0。我不知道为什么。

我的代码的主要部分是：

    private void getImageFromCamera() {
        Intent intent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);
        intent.putExtra(MediaStore.EXTRA_OUTPUT, Uri.fromFile(profileIconFile));

    }

    private void getImageFromAlbum() {
        Intent intent = new Intent(Intent.ACTION_PICK);
        intent.setType(MediaStore.Images.Media.CONTENT_TYPE);

尝试添加cropIntent.putExtra("return-data", true)并检查。

private void performCrop(Uri picUri) {
try {
    Intent cropIntent = new Intent("com.android.camera.action.CROP");
    cropIntent.setDataAndType(picUri, "image/*");
    cropIntent.putExtra("crop", true);
    cropIntent.putExtra("aspectX", 1);
    cropIntent.putExtra("aspectY", 1);
    cropIntent.putExtra("outputX", 128);
    cropIntent.putExtra("outputY", 128);
    cropIntent.putExtra("return-data", true);
    startActivityForResult(cropIntent, PIC_CROP);
}
catch (ActivityNotFoundException e) {
    String errorMessage = "Whoops - your device doesn't support the crop action!";
    Toast.makeText(this, errorMessage, Toast.LENGTH_SHORT).show();
}
}

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

if (requestCode == PIC_CROP) {
    if (data != null) {
        Bundle extras = data.getExtras();
        Bitmap bitmap = extras.getParcelable("data");
        imgView.setImageBitmap(bitmap);
    }
}

}

startActivityForResult（intent，CROP_FROM_ALBUM）在＆＃39; onResultActivity＆＃39;上返回0。方法
