Android – 如何从ClipData获取图像？

我正在创建一个图像上传器,它能够一次上传多个图像.

galerijButton.setonClickListener(new OnClickListener() {
    @Override
    public void onClick(View v) {
        Intent photoPickerIntent = new Intent(Intent.ACTION_PICK);
        photoPickerIntent.putExtra(Intent.EXTRA_ALLOW_MULTIPLE,true);

        photoPickerIntent.setType("image/*");
        startActivityForResult(photoPickerIntent,SELECT_PHOTO);   
    }
});

…

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

    switch(requestCode) { 
    case SELECT_PHOTO:
        if(resultCode == RESULT_OK){  
            if(imageReturnedIntent.getData() != null){
                //If uploaded with Android gallery (max 1 image)
                Uri selectedImage = imageReturnedIntent.getData();
                InputStream imagestream;
                try {
                    imagestream = getContentResolver().openInputStream(selectedImage);
                    Bitmap yourSelectedImage = BitmapFactory.decodeStream(imagestream);
                    photos.add(yourSelectedImage);
                } catch (FileNotFoundException e) {
                    e.printstacktrace();
                }
            } else {
                //If uploaded with the new Android Photos gallery
                ClipData clipData = imageReturnedIntent.getClipData();
                for(int i = 0; i < clipData.getItemCount(); i++){
                    clipData.getItemAt(i);
                    //What Now?
                }
            }
        }
    break;
    ....

我想将所有选定的图像添加到我的照片数组中,这是一个ArrayList< Bitmap> .不知何故,我必须将ClipData.Item转换为Bitmap,但是如何？

解决方法

试试这个

ClipData.Item item = clip.getItemAt(i);
Uri uri = item.getUri();

现在你有了图像的URI.

我猜你现在知道该怎么做了.干杯:)
