我的应用程序具有以下功能：编辑照片，删除照片，拍摄照片，当我捕捉和编辑照片时，我的应用程序中显示的照片发生变化，当用户按下编辑个人资料时，它会将照片更改为我的Firebase数据库作为一个uri。
问题是我有一个定义selectedImage的全局var，而且该变量是一个URI，我需要的是当我捕获照片时从foto获取uri，但是URi uri = data.getData()会导致错误，它只是与捆绑附加功能一起使用，但是我从那里知道URI怎么能这样做呢？
这是代码：
@Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
// Check which request we're responding to
if (requestCode == GALLERY_IMG && resultCode == RESULT_OK) {
selectedimg = data.getData();
try {
userImage.setImageBitmap(MediaStore.Images.Media.getBitmap(this.getContentResolver(), selectedimg));
imageHasChanged = true;
} catch (IOException e) {
e.printStackTrace();
}
}
if (requestCode == IMAGE_CAPTURE && resultCode == RESULT_OK) {
Bundle extra = data.getExtras();
//selectedimg = extra;
try {
userImage.setImageBitmap(MediaStore.Images.Media.getBitmap(this.getContentResolver(), selectedimg));
imageHasChanged = true;
} catch (IOException e) {
e.printStackTrace();
}
}
}
