In a fragmentlayout inside to add a dot is actually page on the basis of completion, in fact, the point of view (view) in the fragment inside and Viewpager without the level, as if you wear a sweater, and now in your clothes on the surface of the nail a few buttons is a phenomenon. Look at the following XML code: <?xml version= "1.0" encoding= "UTF-8"?>
<framelayout xmlns:android= "Http://schemas.android.com/apk/res/android"
Xmlns:tools= "Http://schemas.android.com/tools"

</FrameLayout> After this step, add the corresponding display and operation in Java: private void Initview (View parentview) {
resources = Getresources ();

Dot2 = (View) Parentview.findviewbyid (r.id.dot_2);

Dots.get (0). Setbackgroundresource (r.drawable.dot_focused);
if (config.function_page = = 1) {
Dot2.setvisibility (View.gone);
}else if (config.function_page = = 2) {
Dots.add (Parentview.findviewbyid (r.id.dot_2));
Dot2.setvisibility (view.visible);
}
Mpager = (Viewpager) Parentview.findviewbyid (R.id.pager);
Fragmentslist = new arraylist<fragment> ();
if (config.function_page = = 1) {
home1 = new Mainhomefragmentpiece ();
Fragmentslist.add (HOME1);
} else if (config.function_page = = 2) {
home1 = new Mainhomefragmentpiece ();
Fragmentslist.add (HOME1);
Home2 = new Mainhomefragmentpiecenext ();
Fragmentslist.add (home2);
}
Mpager.setadapter (New Myfragmentpageradapter (Getchildfragmentmanager (),
Fragmentslist));
Mpager.setonpagechangelistener (New Myonpagechangelistener ());
Mpager.setcurrentitem (0);
}
public class Myonpagechangelistener implements Onpagechangelistener {
@Override
public void onpageselected (int arg0) {
Animation Animation = null;
Dots.get (oldposition). Setbackgroundresource (
