解决:我忘记了track.play();最后...
我想在Android智能手机上播放声音(4.0.4 Api等级15)。 我试着听到一些随机噪音,但它不起作用:
public class Sound {
private static int length = 22050 * 10; //10 seconds long
private static byte[] data = new byte[length];
static void fillRandom() {
new Random().nextBytes(data); //Create some random noise to listen to.
}
static void play() {
fillRandom();
final int TEST_SR = 22050; //This is from an example I found online.
final int TEST_CONF = AudioFormat.CHANNEL_OUT_MONO;
final int TEST_FORMAT = AudioFormat.ENCODING_PCM_16BIT;
final int TEST_MODE = AudioTrack.MODE_STATIC; //I need static mode.
final int TEST_STREAM_TYPE = AudioManager.STREAM_ALARM;
AudioTrack track = new AudioTrack(TEST_STREAM_TYPE, TEST_SR, TEST_CONF, TEST_FORMAT, length, TEST_MODE);
track.write(data, 0, length);
}
}
我已经玩了一些变量,但无法让它起作用。
答案 0 :(得分:0)
你剩下要做的就是玩它。将此行添加到play()函数的末尾:
track.play();
