android - How to make a button go to another page? -
okay have section_home layout has button code.
<button style="?android:attr/buttonstylesmall" android:layout_width="wrap_content" android:layout_height="wrap_content" android:background="@color/transparent" android:text="apply" android:textcolor="@color/white" android:elevation="0dp" android:id="@+id/button" android:layout_aligntop="@+id/linearlayout" android:layout_alignparentleft="true" android:layout_alignparentstart="true" /> what want when click's "apply" button go other layout that's called section_apply
<relativelayout xmlns:android="http://schemas.android.com/apk/res/android" android:layout_width="match_parent" android:layout_height="match_parent" android:background="@color/window_bg" android:cliptopadding="false" android:fitssystemwindows="true"> <listview android:id="@+id/launcherslist" android:layout_width="wrap_content" android:layout_height="wrap_content" android:layout_alignparentleft="true" android:layout_alignparentstart="true" android:layout_alignparenttop="true" android:background="@color/light_bg" android:divider="@color/transparent" /> here java class home layout called homefragment.

this looks paperboard template, correct? code should work without issue if place in homefragment , id of button "button".
textview btn = (textview) root.findviewbyid(r.id.button); btn.setonclicklistener(new view.onclicklistener() { @override public void onclick(view v) { ((mainactivity) getactivity()).result.setselectionbyidentifier(3); ((mainactivity) getactivity()).switchfragment(3, getresources().getstring(r.string.section_three), "apply"); } }); edit: changed work code.
