我要完成的工作是，每当我单击单独的Imageview时，都要选择一个清晰的图像。例如，如果单击ImageView_1，则可以从库中选择一张图像；如果单击Imagview_2，则可以从库中选择另一张图像。我已经看到这个问题的答案已经很多，但是它们都与我想做的不同。在先前的答案中，他们将所有图像作为列表显示在OnActivity结果中，并从图库中一次选择所有图像。

您错过了这一行：
intent.putExtra(Intent.EXTRA_ALLOW_MULTIPLE, true);
活动结果应如下所示：
@Override
public void onActivityResult(int requestCode, int resultCode, Intent data) {
super.onActivityResult(requestCode, resultCode, data);
if(requestCode == PICK_IMAGE_REQUEST) {
if(resultCode == Activity.RESULT_OK) {
if(data.getClipData() != null) {
int count = data.getClipData().getItemCount();
for(int i = 0; i < count; i++)
Uri imageUri = data.getClipData().getItemAt(i).getUri();
//TODO: do something; here is your selected images
}
} else if(data.getData() != null) {
String imagePath = data.getData().getPath();
//TODO: do something
}
}
}
意图：
Intent intent = new Intent();
intent.setType("image/*");
intent.putExtra(Intent.EXTRA_ALLOW_MULTIPLE, true);
intent.setAction(Intent.ACTION_GET_CONTENT);
startActivityForResult(Intent.createChooser(intent,"Select images"), PICK_IMAGE_REQUEST);
