我在android中通过fragmentdialog执行fileupload时遇到了问题。在测试我制作的activity等按钮以测试它之前,evrything工作正常,但由于我将它放在dilogfragment下,没有任何工作:
public class UploadF extends DialogFragment{
....
@Override
public Dialog onCreateDialog(Bundle savedInstanceState) {
gallery_button.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
Intent gal = new Intent();
gal.setType("image/*");
gal.setAction(Intent.ACTION_GET_CONTENT);
startActivityForResult(Intent.createChooser(gal, "Select Picture"), SELECT_IMAGE);
}
});
public void onActivityResult(int requestCode, int resultCode, Intent data) {
super.onActivityResult( requestCode, resultCode, data);
if (resultCode == Activity.RESULT_OK) {
if (requestCode == SELECT_IMAGE) {
....
if ( selectedImagePath != null ) {
UploadFileI task = new UploadFileI( getActivity());
task.execute( url );
}
}
}
}
}
最佳答案
你说得对,什么都没发生。Activity
有一种方法,也有一种方法。这可能会令人困惑,为了继续,请尝试通过调用以下命令使用活动上下文:
getActivity().startActivityForResult(Intent.createChooser(gal, "Select Picture"), SELECT_IMAGE);
这样,创建uploadf的活动将收到结果。所以你必须把你的
onActivityResult
移到你的Fragment
:public class YourActivity extends Activity {
...
public void onActivityResult(int requestCode, int resultCode, Intent data){}
...
}
在uploadf外部和父活动内部运行。
如果这不起作用,请在DialogFragment中搜索StartActivityForresult
