android - Where can I add the FindViewById() and the listeners in a fragment? -
i created fragment , called kabar , can see button , textview appears expected.
here fragment:
public class kabar extends fragment { private button button; private textview text; public kabar() { // required empty public constructor } @override public view oncreateview(layoutinflater inflater, viewgroup container, bundle savedinstancestate) { // inflate layout fragment view v= inflater.inflate(r.layout.fragment_kabar , container, false); return v; } } this fragment_kabar layout:
<framelayout xmlns:android="http://schemas.android.com/apk/res/android" xmlns:tools="http://schemas.android.com/tools" android:layout_width="match_parent" android:layout_height="match_parent" tools:context="com.examplee.my.kabar"> <!-- todo: update blank fragment layout --> <relativelayout android:layout_width="match_parent" android:layout_height="match_parent"> <textview android:id="@+id/tt1" android:layout_width="wrap_content" android:layout_height="wrap_content" android:text="mohsen kabar" /> <button android:id="@+id/tt2" android:layout_width="wrap_content" android:layout_height="wrap_content" android:layout_margintop="113dp" android:text="button" android:layout_below="@+id/mohsenkabar" android:layout_alignparentright="true" android:layout_alignparentend="true" android:layout_marginright="93dp" android:layout_marginend="93dp" /> </relativelayout> i need use button , textview.
where can place code?
text=(textview) text.findviewbyid(r.id.tt1); button=(button) button.findviewbyid(r.id.tt2); button.setonclicklistener(new view.onclicklistener() { @override public void onclick(view v) { tt1.settext("kkk mmm bbb ddd"); } });
try add code in kabar fragment
@override public view oncreateview(layoutinflater inflater, viewgroup container, bundle savedinstancestate) { // inflate layout fragment view v= inflater.inflate(r.layout.fragment_kabar , container, false); textview text=(textview) v.findviewbyid(r.id.tt1); textview button=(textview) v.findviewbyid(r.id.tt2); button.setonclicklistener(new view.onclicklistener() { @override public void onclick(view v) { text.settext("kkk mmm bbb ddd"); } }); return v; }
