【问题描述】:
我正在创建一个能够一次上传多个图像的图像上传器。
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> 。我必须以某种方式将ClipData.Item 转换为Bitmap,但是如何?
【问题讨论】:
-
您是否要从剪贴板复制图像?
-
不,我正在使用 Android 照片应用程序一次上传多张图片。 Android Photos 应用程序将所选图像放入 (Intent) imageReturnedIntent.getClipData();我知道这一点,因为该数组的大小始终是所选图像的数量。
