Use SoundPool to play sound effects

The SoundPool class can be used to manage and play audio resources in applications. These audio resources can be placed in storage files or included in programs. Generally speaking, SoundPool is used to play short sound effects, such as various sound effects in games.

First create a SoundPool object

Private SoundPool sp

And then

Create a Builder object with SoundPool.Builder builder

Set the maximum number of audio, setMaxStreams ()

Default audio type, setLegacyStreamType ()

Set the audio type, setAudioAttributes ()

If (Build.VERSION.SDK_INT > = 21) {SoundPool.Builder builder = new SoundPool.Builder (); builder.setMaxStreams (2); AudioAttributes.Builder attrBuilder = new AudioAttributes.Builder (); attrBuilder.setLegacyStreamType (AudioManager.STREAM_MUSIC); builder.setAudioAttributes (attrBuilder.build ()); sp = builder.build () } else {sp = new SoundPool (2, AudioManager.STREAM_SYSTEM, 0);}

Then load the audio file with load and play it with play

Int soundId1=sp.load (this,R.raw.winlog,1); int soundId2=sp.load (this,R.raw.lesson1,2); Button button1= (Button) findViewById (R.id.button1); button1.setOnClickListener (new View.OnClickListener () {@ Override public void onClick (View v) {sp.play (soundId1,1,1,1,0,1);}}) Button button2= (Button) findViewById (R.id.button2); button2.setOnClickListener (new View.OnClickListener () {@ Override public void onClick (View v) {sp.play (soundId2,2,1,1,0,1);}})
