Today I learned how to play audio with the MediaPlayer method in Android, the code below.

Start with a new Android project, place pre-recorded audio music.wma in the Res/raw directory, add a button to the layout file, and the audio will ring when the button is pressed.

1  Public classTestaudioextendsActionbaractivityImplementsOnclicklistener {2 3     PrivateMediaPlayer MP;4 @Override5      Public voidonCreate (Bundle savedinstancestate) {6         Super. OnCreate (savedinstancestate);7 Setcontentview (r.layout.activity_main);8Setvolumecontrolstream (Audiomanager.stream_music);//Indicates that the volume key is pressed to adjust the volume of music or other media, not the volume of the ringtone9 TenButton Btnaudio =(Button) Findviewbyid (r.id.audio); OneBtnaudio.setonclicklistener ( This); A     } -  -      Public voidOnClick (View v) { the         Switch(V.getid ()) { -              CaseR.id.audio: -MP = Mediaplayer.create ( This, r.raw.music); -Mp.start ();//Press the play button and the music rings +                  Break; -         } +}
