Android代码-检测手机耳机插拔

Android代码-----检测手机耳机插拔

AudioManager就有这个方法：isWiredHeadsetOn()；

如果插入了耳机，就返回true,否则false;

当然，要加个权限，不然一直是返回false。

public class TestHeadSetPlugActivity extends Activity {    private HeadsetPlugReceiver headsetPlugReceiver;    /** Called when the activity is first created. */    @Override    public void onCreate(Bundle savedInstanceState) {        super.onCreate(savedInstanceState);        setContentView(R.layout.main);        /* register receiver */        registerHeadsetPlugReceiver();    }    private void registerHeadsetPlugReceiver() {      headsetPlugReceiver = new HeadsetPlugReceiver();    IntentFilter intentFilter = new IntentFilter();      intentFilter.addAction("android.intent.action.HEADSET_PLUG");      registerReceiver(headsetPlugReceiver, intentFilter);    }    @Override    public void onDestroy() {      unregisterReceiver(headsetPlugReceiver);      super.onDestroy();    } }
