Java 接近传感器-静音呼叫应用

我正在尝试构建一个安卓应用程序，当一个人用接近传感器在手机上挥动他的/她的手时，它会使电话静音

我是android开发新手。 我试着让应用程序检查手机是否处于待机状态。如果是，则应用程序检查接近传感器的值是否=0（接近值）。如果接近传感器的值为0，则表示在振铃广告期间传感器被覆盖，因此应使呼叫静音。 但它仍然处于响铃状态

我认为问题在于，ServiceReceiver仅在手机开始响时检查接近传感器的值。如果此时传感器值不为零，则手机不会静音。 那么，我如何让它在整个铃声或来电过程中检查接近传感器的值的变化，以便传感器值一变为零，通话就会静音

第一类“mainactivity”包含接近传感器的代码

package example.ringcheck;


import android.app.Activity;
import android.content.Context;
import android.hardware.Sensor;
import android.hardware.SensorEvent;
import android.hardware.SensorEventListener;
import android.hardware.SensorManager;
import android.media.AudioManager;
import android.os.Bundle;
import android.util.Log;
import android.view.Menu;
import android.widget.TextView;

public class MainActivity extends Activity implements SensorEventListener {
static TextView proxText;
SensorManager sm;
Sensor proxSensor;
static float proxValue = 8;
// static boolean muteCall = false;
private AudioManager amanager;


@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);

    sm = (SensorManager) getSystemService(SENSOR_SERVICE);
    proxSensor = sm.getDefaultSensor(Sensor.TYPE_PROXIMITY);
    proxText = (TextView) findViewById(R.id.ProximityTextView);

    sm.registerListener(this, proxSensor, SensorManager.SENSOR_DELAY_NORMAL);

}



@Override
public boolean onCreateOptionsMenu(Menu menu) {
    // Inflate the menu; this adds items to the action bar if it is present.
    getMenuInflater().inflate(R.menu.activity_main, menu);
    return true;
}

@Override
public void onAccuracyChanged(Sensor arg0, int arg1) {
    // TODO Auto-generated method stub

}

@Override
public void onSensorChanged(SensorEvent event) {


    // TODO Auto-generated method stub
    proxText.setText(String.valueOf(event.values[0]));
    proxValue = event.values[0];
    Log.d("SENSOR VALUE", "********" + proxValue + "*******");



    }

}

package example.ringcheck;
import android.content.BroadcastReceiver;
import android.content.Context;
import android.content.Intent;
import android.media.AudioManager;
import android.telephony.TelephonyManager
import android.util.Log;

public class ServiceReceiver extends BroadcastReceiver {

private AudioManager amanager;
// static boolean isRinging = false;

public void onReceive(Context context, Intent intent) {

    if (intent.getStringExtra(TelephonyManager.EXTRA_STATE).equals(
            TelephonyManager.EXTRA_STATE_RINGING)) {
        // isRinging = true;
            if (MainActivity.proxValue == 0) {
                amanager = (AudioManager) context
                        .getSystemService(Context.AUDIO_SERVICE);
                amanager.setRingerMode(0x00000000);
                // isRinging = false;

            }

    Log.d("MPR", "Its Ringing");



    }
}


}

            }

    Log.d("MPR", "Its Ringing");



    }
}


}

提前感谢：-）

而不是

amanager.setRingerMode(0x00000000);  

试一试

谢谢但是静音功能可以工作。问题在于，该程序仅在手机开始鸣响时检查接近传感器的值，如果没有任何东西覆盖传感器，则振铃器不会静音。但我希望它一直检查，直到响铃停止，接近传感器的值发生变化。
