我用 seekbar 创建了音频活动，它被播放了，但是当我使用 seekbar 时，我遇到了问题，因为我使用了（Thread.sleep），所以每 1 秒的声音就会减少。
我在互联网上检查了另一个解决方案，我检查的所有代码都使用相同的概念。
这是我的代码
public class PlaySounds extends Activity implements Runnable {
SeekBar seeksounds;
MediaPlayer mp;
Handler handler = new Handler();
int id;
public boolean isFileExists(String fileName) {
try {
File myFile = new File(fileName);
FileInputStream fIn = new FileInputStream(myFile);
BufferedReader myReader = new BufferedReader(new InputStreamReader(fIn));
return true;
} catch (Exception e) {
return false;
}
}
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.playsounds);
seeksounds = (SeekBar) findViewById(R.id.seeksounds);
getWindow().setFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN, WindowManager.LayoutParams.FLAG_FULLSCREEN);
String path = Environment.getExternalStorageDirectory().toString() + "/dowload/splash.mp3";
if (isFileExists(path)) {
mp = new MediaPlayer();
try {
mp.setDataSource(path);
mp.prepare();
mp.start();
int maxD = mp.getDuration();
int currentD = mp.getCurrentPosition();
seeksounds.setMax(maxD);
seeksounds.setProgress(currentD);
new Thread(this).start();
seeksounds.setOnSeekBarChangeListener(new OnSeekBarChangeListener() {
@Override
public void onProgressChanged(SeekBar arg0, int progress,
boolean arg2) {
mp.seekTo(progress);
seeksounds.setProgress(progress);
}
@Override
public void onStartTrackingTouch(SeekBar seekBar) {
// TODO Auto-generated method stub
}
@Override
public void onStopTrackingTouch(SeekBar seekBar) {
// TODO Auto-generated method stub
}
});
} catch (Exception e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
}
}
@Override
public void onBackPressed() {
// TODO Auto-generated method stub
super.onBackPressed();
mp.release();
}
@Override
public void run() {
int currentPosition= 0;
int total = mp.getDuration();
while (mp!=null && currentPosition<total) {
try {
Thread.sleep(1000);
currentPosition= mp.getCurrentPosition();
seeksounds.setProgress(currentPosition);
} catch (Exception e) {
return;
}
}
}
}
