[英]Call method from alertdialog onclicklistener (in fragment)
I am stuck in seemingly simple thing but couldn't find a way. 我被看似简单的事情所困扰,但却找不到办法。 I have a method and an alertdialog inside a fragment.
我在片段中有一个方法和一个Alertdialog。 I want to call that method from alertdialog's onclickListener.
我想从alertdialog的onclickListener调用该方法。
The issue is, the method is not recognizable from in side on click listener. 问题是,无法从点击侦听器的侧面识别该方法。 Do I need to use separate DialogFragment and interface?
我是否需要使用单独的DialogFragment和接口? Is there any straight forward way without creating an extra class?
有没有创建额外的类的直接方法?
public class myFragment extends Fragment {
public void samplefile(){
AlertDialog.Builder myDialog = new AlertDialog.Builder(getActivity());
myDialog.setTitle("Dialog Title");
String[] filetypelist = {"A","B","C"};
myDialog.setItems(filetypelist, new DialogInterface.OnClickListener() {
public void onClick(DialogInterface dialog, int which) {
((SettingsFragment) getActivity()).dloadSample(which);
}
});
myDialog.setNegativeButton("CANCEL", new DialogInterface.OnClickListener() {
public void onClick(DialogInterface dialog, int which) {
dialog.cancel();
}
});
myDialog.create().show();
}
public void dloadSample(int args) {
//SOMETHING TO DO HERE
}
}
Add this in your method: 在您的方法中添加:
getActivity()
.getFragmentManager()
.beginTransaction()
.replace(android.R.id.content, new nameOfYourFragmentToBeCalled())
.commit();`
