android 4.2获取不到手机信号强度
4.2获取信号强度的监听没有改啊.为什么现在每次获取都是0啊.
public class MainActivity extends Activity {
private TelephonyManager Tel;
private MyPhoneStateListener MyListener;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
MyListener = new MyPhoneStateListener();
Tel = (TelephonyManager) getSystemService(Context.TELEPHONY_SERVICE);
Tel.listen(MyListener, PhoneStateListener.LISTEN_SIGNAL_STRENGTHS);
}
private class MyPhoneStateListener extends PhoneStateListener
{
@Override
public void onSignalStrengthsChanged(SignalStrength signalStrength)
{
super.onSignalStrengthsChanged(signalStrength);
Toast.makeText(getApplicationContext(),"Go to Firstdroid!!! GSM Cinr = "+ String.valueOf(signalStrength.getGsmSignalStrength()),
Toast.LENGTH_SHORT).show();
}
};
@Override
protected void onPause()
{
super.onPause();
Tel.listen(MyListener, PhoneStateListener.LISTEN_NONE);
}
/* Called when the application resumes */
@Override
protected void onResume()
{
super.onResume();
Tel.listen(MyListener, PhoneStateListener.LISTEN_SIGNAL_STRENGTHS);
}
}
android
信号强度
