Android 監聽Screen

在這個專案必須實做兩個BroadcastReceiver以及Service，依序命名為MyBoot、FilterScreen和MyService

MyBoot用於監聽開機並且啟動MyService，透過MyService去攔截螢幕ON的訊號，攔截到則會有在LogCat info顯示出來

package com.cyfang.filter.screen;

import android.content.BroadcastReceiver;
import android.content.Context;
import android.content.Intent;

public class MyBoot extends BroadcastReceiver {
    @Override
    public void onReceive(Context context, Intent intent) {
        if (intent.getAction().equals(Intent.ACTION_BOOT_COMPLETED)) {
            Intent start = new Intent(context, MyService.class);
            context.startService(start);
        }
    }
}

package com.cyfang.filter.screen;

import android.content.BroadcastReceiver;
import android.content.Context;
import android.content.Intent;
import android.util.Log;

public class FilterScreen extends BroadcastReceiver {
    @Override
    public void onReceive(Context context, Intent intent) {
        if (intent.getAction().equals(Intent.ACTION_SCREEN_ON)) {
            Log.i("Tag", "Screen On");
        }
    }
}

package com.cyfang.filter.screen;

import android.app.Service;
import android.content.Intent;
import android.content.IntentFilter;
import android.os.IBinder;

public class MyService extends Service {

    @Override
    public IBinder onBind(Intent intent) {
        return null;
    }

    @Override
    public void onStart(Intent intent, int startId) {
        IntentFilter filter = new IntentFilter(Intent.ACTION_SCREEN_ON);
        filter.addAction("android.intent.action.SCREEN_ON");
        FilterScreen filterScreen = new FilterScreen();
        registerReceiver(filterScreen, filter);
    }
}
