手机卫士09-防盗逻辑实现-阿里云开发者社区

好啦，我们之前已经把设置向导的界面已经全部完成的了，而且界面也已经完成了三个的啦，今天我们把最后的一个界面完成它，还有把防盗的逻辑也完成一下

废话不多说，直接上代码

com.xiaobin.security.ui.SetupGuide4Activity

package com.xiaobin.security.ui;
import android.app.Activity;
import android.app.AlertDialog;
import android.content.Context;
import android.content.DialogInterface;

import android.widget.CompoundButton.OnCheckedChangeListener;
import com.xiaobin.security.R;
public class SetupGuide4Activity extends Activity implements OnClickListener
{
private Button bt_pervious;
private Button bt_finish;
private CheckBox cb_protected;
private SharedPreferences sp;
@Override

{
super.onCreate(savedInstanceState);
setContentView(R.layout.setup_guide4);
bt_pervious = (Button) findViewById(R.id.bt_guide_pervious);
bt_finish = (Button) findViewById(R.id.bt_guide_finish);
bt_finish.setOnClickListener(this);
bt_pervious.setOnClickListener(this);
cb_protected = (CheckBox) findViewById(R.id.cb_guide_protected);
sp = getSharedPreferences("config", Context.MODE_PRIVATE);
boolean isProtecting = sp.getBoolean("isProtected", false);
if(isProtecting)
{
cb_protected.setText("已经开启保护");
cb_protected.setChecked(true);
}
cb_protected.setOnCheckedChangeListener(new OnCheckedChangeListener()
{
@Override
public void onCheckedChanged(CompoundButton buttonView, boolean isChecked)
{
if(isChecked)
{

Editor editor = sp.edit();
editor.putBoolean("isProtected", true);
editor.commit();
}
else
{
cb_protected.setText("没有开启保护");
Editor editor = sp.edit();
editor.putBoolean("isProtected", false);
editor.commit();
}
}
});
}
@Override
public void onClick(View v)
{
switch(v.getId())
{
case R.id.bt_guide_finish :
if(cb_protected.isChecked())
{
Editor editor = sp.edit();
editor.putBoolean("setupGuide", true);//记录是否已经进行过设置向导了
editor.commit();
finish();
}
else
{
AlertDialog.Builder builder = new AlertDialog.Builder(this);
builder.setTitle("提醒");
builder.setMessage("强烈建议您开启保护, 是否完成设置");
builder.setCancelable(false);
builder.setPositiveButton(android.R.string.ok, new DialogInterface.OnClickListener()
{
@Override
public void onClick(DialogInterface dialog, int which)
{
Editor editor = sp.edit();
editor.putBoolean("setupGuide", true);//记录是否已经进行过设置向导了
editor.commit();
finish();
}
});
builder.setNegativeButton(android.R.string.no, new DialogInterface.OnClickListener()
{
@Override
public void onClick(DialogInterface dialog, int which)
{
Editor editor = sp.edit();
editor.putBoolean("setupGuide", true);//记录是否已经进行过设置向导了
editor.commit();
}
});
builder.create().show();
}
break;
case R.id.bt_guide_pervious :
Intent intent = new Intent(this, SetupGuide3Activity.class);
finish();
startActivity(intent);
//这个是定义activity切换时的动画效果的
overridePendingTransition(R.anim.alpha_in, R.anim.alpha_out);
break;
default :
break;
}
}
}

好啦，就这个样子，我们的设置向导就全部完成的啦，现在我们就要来写完我们的防盗主界面啦，lost_protected.xml

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical" >
<TextView
android:id="@+id/tv_lost_protected_number"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_marginTop="5dip"
android:text="@string/lostProtectedNumber"
android:textSize="20sp"/>
<View
style="@style/SetGuideUnderline"/>
<CheckBox

android:layout_width="wrap_content"

好啦，到现在为止，我们的手机防盗这个功能的界面就基本上完成的啦，那么现在就进入我们的重头戏啦，就是防盗逻辑的完成啦，我们现在的防盗是这样的，手机丢失的时候，小偷肯定是会换sim卡的嘛，所以就要重启啦，那我们就在启动完成之后，比较一下现在的sim卡，是不是我们之前设置保护的sim卡，如果不是，那就发送一条短信到已经设置了的安全号码那里。所以现在我们只要写一个广播接收者，把手机重启的广播接收到，然后再起进行判断就行啦好啦，现在直接上代码com.xiaobin.security.receiver.BootCompleteReceiver

package com.xiaobin.security.receiver;
import android.content.BroadcastReceiver;
import android.content.Context;
import android.content.Intent;
import android.content.SharedPreferences;
import android.telephony.SmsManager;
import android.telephony.TelephonyManager;
public class BootCompleteReceiver extends BroadcastReceiver
{
private SharedPreferences sp;
@Override
public void onReceive(Context context, Intent intent)
{
sp = context.getSharedPreferences("config", Context.MODE_PRIVATE);
boolean isProtected = sp.getBoolean("isProtected", false);
//看看是不是开启了保护
if(isProtected)
{
TelephonyManager telephonyManager = (TelephonyManager) context.getSystemService(Context.TELEPHONY_SERVICE);
//开机后，拿到当前sim卡的标识，与我们之前存放的标识对比
String currentSim = telephonyManager.getSimSerialNumber();
String protectedSim = sp.getString("simSerial", "");
if(!currentSim.equals(protectedSim))
{
//拿到一个短信的管理器，要注意不要导错包，是在android.telephony下的
SmsManager smsManager = SmsManager.getDefault();
String number = sp.getString("number", "");
//发送短信，有5个参数，第一个是要发送到的地址，第二个是发送人，可以设置为null，第三个是要发送的信息，第四个是发送状态，第五个是发送后的，都可以置为null
smsManager.sendTextMessage(number, null, "Sim卡已经变更了，手机可能被盗", null, null);
}
}
}
}

复制代码

好啦，现在我们就要在AndroidManifest文件里面注册这个广播接收者啦

<receiver
android:name="com.xiaobin.security.receiver.BootCompleteReceiver">
<intent-filter android:priority="1000">
<action android:name="android.intent.action.BOOT_COMPLETED"/>
</intent-filter>
</receiver>

复制代码

当然，现在还不行的，我们还要把相应的权限加上

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

复制代码

好啦，现在我们的逻辑就基本上完成的啦但现在这个功能还不是很完整，所以我们后续的课程将会继续完善这个防盗的功能的，比如加入gps定位啦，这些的。好，今天的代码就到这里了，如果有什么不明白的，和指导的，欢迎留言！，明天将会完善这个防盗功能，加入gps！
