Android Sound Playback

Android Play sound, one is Soundpool, one is MediaPlayer

Soundpool is suitable for playback of sound effects that reflect high speed requirements, such as in-game explosion sound

Mediaplay for longer sound effects, such as in-game background music

Let's do an example, one is Chang.ogg, the other is duan.wav.

These two sound effect files, I was from my game directory in the laughter of the lake ol in the search out. You can also search for *.ogg,*.wav under your game folder

Place these two files in the Res/raw directory, and if the raw directory does not exist, create it

Define Activity_main.xml, put a TextView and 4 buttons inside

<LinearLayoutxmlns:android= "Http://schemas.android.com/apk/res/android"Xmlns:tools= "Http://schemas.android.com/tools"Android:id= "@+id/linearlayout1"Android:layout_width= "Match_parent"Android:layout_height= "Match_parent"android:orientation= "vertical"Android:paddingbottom= "@dimen/activity_vertical_margin"Android:paddingleft= "@dimen/activity_horizontal_margin"Android:paddingright= "@dimen/activity_horizontal_margin"Android:paddingtop= "@dimen/activity_vertical_margin"Tools:context= "Com.ssln.sound.MainActivity" >    <TextViewAndroid:id= "@+id/tvmsg"Android:layout_width= "Wrap_content"Android:layout_height= "Wrap_content"Android:text= "No sound is played" />    <ButtonAndroid:id= "@+id/button1"Android:layout_width= "Match_parent"Android:layout_height= "Wrap_content"Android:text= "SoundPlayer Play" />    <ButtonAndroid:id= "@+id/button2"Android:layout_width= "Match_parent"Android:layout_height= "Wrap_content"Android:text= "SoundPlayer Stop" />    <ButtonAndroid:id= "@+id/button3"Android:layout_width= "Match_parent"Android:layout_height= "Wrap_content"Android:text= "MediaPlayer Play" />    <ButtonAndroid:id= "@+id/button4"Android:layout_width= "Match_parent"Android:layout_height= "Wrap_content"Android:text= "MediaPlayer Stop" /></LinearLayout>

Then we implement the Click button to play and stop the sound in Mainactivity.java

PlaySound (1, 0);        Tvmsg.settext ("Soundpool play");            } else if (v = = btnsoundstop) {msound.pause (1);        Tvmsg.settext ("Soundpool suspended"); }else if (V==btnmediastart) {
if (!mplayer.isplaying ()) Mplayer.start ();        Tvmsg.settext ("MediaPlayer play"); }else if (v==btnmediastop) {
if (mplayer.isplaying ()) Mplayer.pause ();        Tvmsg.settext ("MediaPlayer suspended");  }}/** * Initialize sound * */private void Initsounds () {//set playback sound MPlayer = Mediaplayer.create (This,        R.raw.chang);        The first parameter is the maximum number of simultaneous data streams, the second data stream type, and the third is the sound quality msound = new Soundpool (4, Audiomanager.stream_music, 100); Soundpoolmap = new HashMap<Integer, Integer>();        Soundpoolmap.put (1, Msound.load (this, R.raw.duan, 1));            You can continue to put the audio file in the back}/** * Soundpool play * * @param sound * Play first * @param loop *                Whether to loop */private void PlaySound (int sound, int loop) {Audiomanager mgr = (Audiomanager) This        .

The program works as follows:
