手机翻转静音

首先通过Activity 界面开启 翻转静音的Service

import java.util.List;

import android.app.Activity;
import android.app.ActivityManager;
import android.content.Context;
import android.content.Intent;
import android.hardware.Sensor;
import android.hardware.SensorEvent;
import android.hardware.SensorEventListener;
import android.os.Bundle;
import android.util.Log;
import android.view.WindowManager;
import android.widget.CompoundButton;
import android.widget.Toast;
import android.widget.CompoundButton.OnCheckedChangeListener;
import android.widget.ToggleButton;

public class PhoneSensorActivity extends Activity{

	Context c = PhoneSensorActivity.this;
	
	public static final String SERVICE_NAME = "com.goso.jamin.TurningService";
	private static final String className = "com.goso.jamin.TurningService";
	private static String TAG = "PhoneSensorActivity";
	
	/** Called when the activity is first created. */
	@Override
	public void onCreate(Bundle savedInstanceState) {
		super.onCreate(savedInstanceState);
		setContentView(R.layout.main);

		ToggleButton serviceSwitch = (ToggleButton) findViewById(R.id.toggleButton1);
		final Intent intent = new Intent(PhoneSensorActivity.this , TurningService.class);//用于开启service的Intent
		serviceSwitch.setChecked(isServiceRunning (this , SERVICE_NAME));//根据服务是否运行，首先设置toggleButton是否开启
		serviceSwitch.setOnCheckedChangeListener(new OnCheckedChangeListener() {

			public void onCheckedChanged(CompoundButton buttonView, boolean isChecked) {
				// TODO Auto-generated method stub
				if(isChecked == true){
					startService(intent);
					Toast.makeText(c, "翻转静音功能 开启", Toast.LENGTH_SHORT).show();
				}else{
					stopService(intent);
					Log.d(TAG, "serviceRun ? = " + isServiceRunning (PhoneSensorActivity.this , SERVICE_NAME));
					Toast.makeText(c, "翻转静音功能 关闭", Toast.LENGTH_SHORT).show();
				}
			}
		});

	}

	private boolean isServiceRunning(PhoneSensorActivity phoneSensorActivity,
			String serviceName) {
		// TODO Auto-generated method stub
		boolean isRunning = false;
		ActivityManager activityManager = (ActivityManager) c.getSystemService(ACTIVITY_SERVICE);

		List<ActivityManager.RunningServiceInfo> serviceList = activityManager.getRunningServices(Integer.MAX_VALUE);
		if(! (serviceList.size()>0)){
			return false;
		}
		for(int i = 0 ; i < serviceList.size() ; i++){
			Log.d(TAG, "第" + i + "个 = " + serviceList.get(i).service.getClassName());
			if(serviceList.get(i).service.getClassName().equals(className)){
				isRunning = true;
				break;
			}
		}
		return isRunning;
		
	}
	
}

Service里这样写

如此手机翻转静音已经实现～

import java.util.List;

import android.hardware.Sensor;
import android.hardware.SensorEvent;
import android.hardware.SensorEventListener;

import android.util.Log;

public class TurningService extends Service {

	private static final String TAG = "TurningService====";

	private SensorEventListener mListener;

	private SensorManager mSensorManager;


	private int StatusFlag;


	@Override
	public IBinder onBind(Intent intent) {
		// TODO Auto-generated method stub
		return null;
	}


	@Override

		//get the sensor service and the audio service
		mSensorManager = (SensorManager) this.getSystemService(SENSOR_SERVICE);

		/////////配置感应监听器
		mListener = new SensorEventListener() {

				case 1: 
					if(event.values[2] > 8){
//						Log.d(TAG , " change to Ringing mode ");
						mAudioManager.setRingerMode(AudioManager.RINGER_MODE_NORMAL);
						mAudioManager.setVibrateSetting(AudioManager.VIBRATE_TYPE_RINGER, AudioManager.VIBRATE_SETTING_ON);
						StatusFlag = 0;
						break;
					}

						mAudioManager.setVibrateSetting(AudioManager.VIBRATE_TYPE_RINGER, AudioManager.VIBRATE_SETTING_OFF);
						StatusFlag = 1;
						break;
					}
				default:
					break;
				}


			}
		};
		/////////////////////////////////////////////////////////////////////////
		List<Sensor> mSensorList = mSensorManager.getSensorList(Sensor.TYPE_ALL);
		int size = mSensorList.size();
		for(int i = 0 ; i <size ; i++){

//			Log.d(TAG, "mSensorList.size() = " + mSensorList.size());
//			Log.d(TAG, "mSensorList = " + mSensorList);
			
			if(mSensorList!=null && (mSensorList.size()>0)){
				Sensor sensor = mSensorList.get(0);
				mSensorManager.registerListener(mListener, sensor,SensorManager.SENSOR_DELAY_NORMAL);
			}else {
//				Log.d(TAG, "sensor is null");
			}
		}

	}


	@Override
	public void onDestroy() {
		// TODO Auto-generated method stub
		super.onDestroy();
		mSensorManager.unregisterListener(mListener);
	}
	
	




}

由于Android模拟器没有sensor功能，所以需要手机测试，或者是下载一个sensor simulator
