我想知道我目前在
Android上的手机信号塔的信号强度.经过一些研究后我发现,我应该使用一个PhoneStateListener来监听更新以获取值(陌生的方式来做恕我直言).
所以我想在得到信号后立即得到信号,然后停止听众.这是我使用的代码：
// object containing the information about the cell
MyGSMCell myGSMCell = new MyGSMCell(cid,lac);
// object listening for the signal strength
new GetGsmSignalStrength(myGSMCell,context);
...
public class GetGsmSignalStrength {
private MyGSMCell callback;
private TelephonyManager telMan;
private MyPhoneStateListener myListener;
public GetGsmSignalStrength(MyGSMCell callback,Context context) {
this.callback = callback;
this.myListener = new MyPhoneStateListener();
this.telMan = (TelephonyManager) context.getSystemService(Context.TELEPHONY_SERVICE);
this.telMan.listen(this.myListener,PhoneStateListener.LISTEN_SIGNAL_STRENGTHS);
}
private class MyPhoneStateListener extends PhoneStateListener
{
public void onSignalStrengthsChanged(SignalStrength signalStrength)
{
// get the strength
super.onSignalStrengthsChanged(signalStrength);
// return it to the MyGSMCell object to set the value
callback.setStrength(signalStrength.getGsmSignalStrength());
}
}
}
我一发送setStrength(值)就想停止听众
任何的想法 ？
谢谢
