您可能已经注意到,在较新的 Android 版本上,Android 现在有 2 个图片库:图库和照片。将来,谷歌将弃用并删除图库,只保留照片库。
我想让用户能够使用 Android API 级别 18+“.putExtra(Intent.EXTRA_ALLOW_MULTIPLE, true);”选择多个图像进行上传。问题是,如果用户选择从图库上传,则该功能不起作用(只能选择一张图片)。
如何确保应用程序自动尝试通过 Android Photo 的应用程序上传?
到目前为止,这是我的代码:
galerijButton.setOnClickListener(new OnClickListener() {
@Override
public void onClick(View v) {
Intent photoPickerIntent = new Intent(Intent.ACTION_PICK);
if(Build.VERSION.SDK_INT >= 18 ){
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);
// more code logic
}
}
}
break;
