如何改变安卓接近感应器的灵敏度?
我编写了一个基于接近传感器的应用,但我希望能够让用户能够更改传感器的灵敏度。 有可能吗?如果是,应如何操作?
解决方案
只需"实现SensorEventListener"并遵循代码:
public void onCallStateChanged(int state, String incomingNumber) {
switch (state) {
case TelephonyManager.CALL_STATE_IDLE:
System.out.println("My Call IDLE");
CallState = false;
StartAudioSpeacker();
System.out.println("Is phone speaker : "+ audioManager.isSpeakerphoneOn());
if (audioManager.isSpeakerphoneOn()) {
audioManager.setSpeakerphoneOn(false);
mSensorManager.unregisterListener(this);
}
break;
case TelephonyManager.CALL_STATE_OFFHOOK:
System.out.println("My Call OFFHOOK");
CallState = true;
StartAudioSpeacker();
System.out.println("Is phone speaker : "+ audioManager.isSpeakerphoneOn());
break;
case TelephonyManager.CALL_STATE_RINGING:
System.out.println("My Call RINGING");
break;
}
}
