Objective
Create a complete available Android player has many features and details to be completed, but also involves a variety of knowledge and content, this chapter will be combined with fragment, Viewpager to build the main player interface, and achieve local playback basic functions. Series of articles to provide screenshots, code description, source download, Welcome to communicate!

1.Android uses Vitamio to build its own universal player (1)--ready
2,Android uses Vitamio to build its own universal player (2)--gesture control brightness, volume, zoom
Body
I. Objectives
1.1 Use fragment, Viewpager to build the main interface
Main function area is divided into: local video, online video, allow sliding switch module
1.2 Display SDcard all video with ListView
Screenshot of Effect:
(statement: Icons are from the network, only for learning research!)
Second, the implementation of the Code
2.1 XML
<?xml version= "1.0" encoding= "Utf-8"?> <linearlayout xmlns:android= "http://schemas.android.com/apk/res/" Android "android:orientation=" vertical "android:gravity=" center_horizontal "android:layout_width=" Match_parent " android:layout_height= "Match_parent" > <radiogroup android:gravity= "center_vertical" Fill_parent "android:layout_height=" wrap_content "android:orientation=" horizontal "> <RadioButton android:id= "@+id/radio_file" android:checked= true "style=" @style/main_tab_bottom "android:drawabletop=" @drawable/video_file "Android:text=" @string/title_file "/> <radiobutton android:id=" @+id/radio_online "android:drawabletop=" @ Drawable/video_online "style=" @style/main_tab_bottom "android:text=" @string/title_online "/> </radiogroup > <android.support.v4.view.viewpager android:background= "@color/background" android:id= "@+id/pager" Android: Layout_width= "Match_parent" android:layout_height= "match_parent" > </android.suPport.v4.view.viewpager> </LinearLayout>
This is the overall layout, use RadioButton to switch local video and online video features, specific styles please download items. Viewpager support left and right side sideslip switch function.
2.2 Class
mainfragmentactivity
public class Mainfragmentactivity extends Fragmentactivity {
private viewpager Mpager;
@Override
protected void onCreate (Bundle savedinstancestate) {
super.oncreate (savedinstancestate);
Setcontentview (R.layout.fragment_pager);
Mpager = (Viewpager) Findviewbyid (R.id.pager);
Mpager.setadapter (Madapter);
}
Private Fragmentpageradapter Madapter = new Fragmentpageradapter (Getsupportfragmentmanager ()) {
/** only execute once/
@Override public
Fragment getitem (int position) {
Fragment result = null;
Switch (position) {case
1: Result
= new Fragmentonline ();//online video break
;
Case 0:
default: Result
= new Fragmentfile ()//local video break
;
}
return result;
}
@Override public
int GetCount () {return 2;}}
;
}
Here is a simple example of the use of fragment in conjunction with Viewpager.
Fragmentfile
public class Fragmentfile extends Fragmentbase implements Onitemclicklistener {private Fileadapter madapter; @Override public View Oncreateview (layoutinflater inflater, ViewGroup container, Bundle savedinstancestate) {View v = s
Uper.oncreateview (Inflater, container, savedinstancestate);
Madapter = new Fileadapter (getactivity (), NULL);
Mlistview.setadapter (Madapter);
Mlistview.setonitemclicklistener (this);
New Scanvideotask (). Execute ();
return v; /** Click Start Play * * @Override public void Onitemclick (adapterview<?> parent, view view, int position, long id) {fi
nal File f = madapter.getitem (position);
Intent Intent = new Intent (getactivity (), videoviewdemo.class);
Intent.putextra ("Path", F.getpath ());
StartActivity (Intent); /** Scan SD Card */private class Scanvideotask extends Asynctask<void, File, void> {@Override protected Void doin
Background (Void ... params) {Eachallmedias (Environment.getexternalstoragedirectory ());
return null; } @Override Protected void Onprogressupdate (File ... values) {Madapter.add (values[0]);
Madapter.notifydatasetchanged (); /** traverse all folders to find out the video file */public void Eachallmedias (file f) {if (f!= null && f.exists () && F.isdirect
Ory ()) {file[] files = f.listfiles ();
if (Files!= null) {for (file File:f.listfiles ()) {if (File.isdirectory ()) {Eachallmedias (file);
else if (file.exists () && file.canread () && fileutils.isvideooraudio (file)) {publishprogress (file); '}}}} Private class Fileadapter extends Arrayadapter<file> {public Fileadapter (context CTX, Arraylis
T<file> l) {super (CTX, L);
@Override public View getview (int position, View Convertview, ViewGroup parent) {final File F = getitem (position);
if (Convertview = null) {final Layoutinflater minflater = getactivity (). Getlayoutinflater ();
Convertview = minflater.inflate (R.layout.fragment_file_item, NULL); } ((TextView) Convertview.findviewbyid (r.id.title)). SETtext (F.getname ());
return convertview; }
}
}
Code Description:
a). Here is the main feature of this chapter, scanning all video audio files and displaying them.
b). Arrayadapter and fileutils here do not stick to the code, mainly tools and auxiliary classes, please download the project view.
c). Note:The madapter.add operation should be placed in the main thread, otherwise there may be an error.
The above is to the Android Vitamio local playback of data collation, follow-up continue to add thank you.
