知识点：

1 左右滑屏切换Activity功能

2 绑定SIM卡

3 使用broadcastreceiver实现监听手机重启功能

1 左右滑屏切换Activity

利用GestureDetector可方便的判断左右滑屏以及滑屏速度等功能，注意：需要将声明的GestureDetector给onTouchEvent事件才能检测到滑屏事件的产生。

在一个方法中声明GestureDetector，并匿名内部类填写onGestureListener:

private GestureDetector gestureDetector; gestureDetector = new GestureDetector(this, new OnGestureListener() {@Overridepublic boolean onSingleTapUp(MotionEvent e) {// TODO Auto-generated method stubreturn false;}@Overridepublic void onShowPress(MotionEvent e) {// TODO Auto-generated method stub}@Overridepublic boolean onScroll(MotionEvent e1, MotionEvent e2, float distanceX, float distanceY) {// TODO Auto-generated method stubreturn false;}@Overridepublic void onLongPress(MotionEvent e) {// TODO Auto-generated method stub}@Overridepublic boolean onFling(MotionEvent e1, MotionEvent e2, float velocityX, float velocityY) {if((e2.getRawX()-e1.getRawX())>200) //向右滑动{showperviouspage();}if((e1.getRawX()-e2.getRawX())>200) //向左滑动{shownextpage();}return false;}@Overridepublic boolean onDown(MotionEvent e) {// TODO Auto-generated method stubreturn false;}});

将gestureDetector传给OnTouchEvent:

@Overridepublic boolean onTouchEvent(MotionEvent event) {gestureDetector.onTouchEvent(event);return super.onTouchEvent(event);}

2 绑定SIM卡

1 对于SiM卡的绑定用到了系统的函数，其实就是读取SIM卡中的序列号，并使用SharedPreferences保存。

得到手机SIM卡序列号：

TelephonyManager telephony = (TelephonyManager) getSystemService(TELEPHONY_SERVICE);String simSerialNumber = telephony.getSimSerialNumber();

2 将数据储存在SharedPreferences:

sharedPreferences.edit().putString("sim", simSerialNumber).commit();

3 删除SharedPreferences：

sharedPreferences.edit().remove("sim").commit();

得到读取权限：

<uses-permission android:name="android.permission.READ_PHONE_STATE"/>

3 使用broadcastreceiver实现监听手机重启功能

1 获得重启监听权限：

<uses-permission android:name="android.permission.RECEIVE_BOOT_COMPLETED"/>

2 设置intent-filter：

<receiver android:name="com.example.mobliesoft.receive.BootCompleteRecevier">            <intent-filter>                <!-- 监听开机事件 -->                <action android:name="android.intent.action.BOOT_COMPLETED" />            </intent-filter>        </receiver>

3 编写一个类继承broadcastreceiver

package com.example.mobliesoft.receive;import android.content.BroadcastReceiver;import android.content.Context;import android.content.Intent;import android.content.SharedPreferences;import android.telephony.TelephonyManager;import android.text.TextUtils;public class BootCompleteRecevier extends BroadcastReceiver {@Overridepublic void onReceive(Context context, Intent arg1) {// TODO Auto-generated method stubSharedPreferences sharedPreferences = context.getSharedPreferences("config", context.MODE_PRIVATE);String sim = sharedPreferences.getString("sim", null);System.out.println("接收到广播监听！！！");if(!TextUtils.isEmpty(sim)){TelephonyManager Sim_card = (TelephonyManager) context.getSystemService(context.TELEPHONY_SERVICE);String simSerialNumber = Sim_card.getSimSerialNumber();if(simSerialNumber.equals(sim)){System.out.println("手机安全！！！");}else{System.out.println("手机危险！！！");}}}}
