Basic Maintenance

First of all, let's take a look at this time to achieve the effect:

The layout is as follows:

<linearlayout 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 "Android:orien tation= "vertical" tools:context= "com.example.googlemedia.MainActivity" > <edittext android:id= "@+id/edi T_musicpath "android:layout_width=" match_parent "android:layout_height=" wrap_content "android:hint=" output Into the path you like the song "/> <linearlayout android:layout_width=" match_parent "android:layout_height=" wrap_content "android:orientation=" Horizontal "> <button android:id=" @+id/btn_play "Android:            Layout_width= "Wrap_content" android:layout_height= "wrap_content" android:onclick= "PlayEvent" android:text= "Play"/> <button android:id= "@+id/btn_pause" android:layout_width= "wrap _content "android:layout_height=" WraP_content "android:onclick=" pauseevent "android:text=" pause "/> <button Android            : id= "@+id/btn_stop" android:layout_width= "wrap_content" android:layout_height= "Wrap_content" android:onclick= "Stopevent" android:text= "Stop"/> <button android:id= "@+id/btn_repla Y "android:layout_width=" wrap_content "android:layout_height=" Wrap_content "android:oncli ck= "Replayevent" android:text= "Replay"/> </LinearLayout></LinearLayout>

Demo Complete

Audio files:

Play button Event:

     public void playevent (view view) {edittext= (EditText) Findviewbyid (R.id.edit_musicpath);      String Pathstring=edittext.gettext (). toString (). Trim ();      File File=new file (pathstring);  if (file.exists ()) {try {mediaPlayer = new MediaPlayer ();  Mediaplayer.setaudiostreamtype (Audiomanager.stream_music);  Mediaplayer.setdatasource (pathstring);  Mediaplayer.prepare ();  Mediaplayer.start ();  Multiple Click play button Easy Mix btn_playbutton.setenabled (false); Set Display Mediaplayer.setoncompletionlistener (new Oncompletionlistener () {@Overridepublic Void when callback is required after playback Oncompletion (MediaPlayer MP) {//TODO auto-generated Method Stub btn_playbutton.setenabled (true);}});} catch (IllegalArgumentException e) {//TODO auto-generated catch Blocke.printstacktrace ();} catch (SecurityException e) { TODO auto-generated catch Blocke.printstacktrace ();} catch (IllegalStateException e) {//Todo auto-generated catch Blocke.printstacktrace ();} catch (IOException e) {//Todo Au To-generated Catch Blocke. Printstacktrace ();}}     else {Toast.maketext (this, "Sorry, there is a problem with the path you entered, please check carefully", toast.length_short). Show (); }

Playback effect:

Pause and Resume Events:

         Public  void  pauseevent (view view) {     if (Btn_pausebutton.gettext (). Equals ("continue")) {Mediaplayer.start (); Btn_pausebutton.settext ("pause"); return;}     if (mediaplayer!=null&&mediaplayer.isplaying ()) {     mediaplayer.pause ();     Btn_pausebutton.settext ("Continue");}     }

Pause and Resume Effects:

Stop event:

    Public  void Stopevent (view view) {     if (mediaplayer!=null&&mediaplayer.isplaying ()) {     Btn_ Playbutton.setenabled (true);     Mediaplayer.stop ();     Release MediaPlayer Otherwise the memory     Mediaplayer.release () will be consumed;     Mediaplayer=null;}     Btn_pausebutton.settext ("pause");     Btn_playbutton.setenabled (True);     }

Replay Event:

     Public  void  replayevent (view view) {     if (mediaplayer!=null&&mediaplayer.isplaying ()) {     mediaplayer.seekto (0);} else {playevent (view);}     The playback status should be set when replaying     btn_playbutton.setenabled (TRUE);     }
