左右滑动切换Activity_绑定SIM_BroadcastReceiver监听手机重启

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() {

@Override
public boolean onSingleTapUp(MotionEvent e) {
// TODO Auto-generated method stub
return false;
}

@Override
public void onShowPress(MotionEvent e) {
// TODO Auto-generated method stub

}

@Override
public boolean onScroll(MotionEvent e1, MotionEvent e2, float distanceX, float distanceY) {
// TODO Auto-generated method stub
return false;
}

@Override
public void onLongPress(MotionEvent e) {
// TODO Auto-generated method stub

}

@Override
public 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;
}

@Override
public boolean onDown(MotionEvent e) {
// TODO Auto-generated method stub
return false;
}
});

将gestureDetector传给OnTouchEvent:

@Override
public 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 {

@Override
public void onReceive(Context context, Intent arg1) {
// TODO Auto-generated method stub

SharedPreferences 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！！！");
}

}
}

}
