android 震动和提示音
简短记录下android震动和提示音编写代码,方便以后编写
首先震动需要权限:
<uses-permission android:name="android.permission.WRITE_SETTINGS" />
然后就直接使用
1 private Vibrator vibrator;//震动 2 private MediaPlayer mediaplayer;//提示音
这里就是开始震动和启动提示音
//震动 vibrator = (Vibrator) getSystemService(Context.VIBRATOR_SERVICE); vibrator.vibrate(3000l); // 铃声(这里是先释放掉内存) if(mediaplayer!=null){ mediaplayer.stop(); mediaplayer.release(); mediaplayer = null; } mediaplayer = new MediaPlayer(); try { mediaplayer.setDataSource(UpLoadService.this, RingtoneManager.getDefaultUri(RingtoneManager.TYPE_NOTIFICATION)); mediaplayer.prepare(); } catch (Exception e) { e.printStackTrace(); } mediaplayer.start();
震动和提示音的取消方式
1 vibrator.cancel(); 2 if(mediaplayer.isPlaying()){ 3 mediaplayer.stop(); 4 }
尽量考虑全面点释放掉内存
@Override protected void onDestroy() { if(mediaplayer!=null){ mediaplayer.stop(); mediaplayer.release(); mediaplayer = null; } super.onDestroy(); }
