「短信拦截」Android编写短信拦截器

短信拦截

这次写的软件是拦截垃圾短信的程序，使用了广播，自定义适配器和listview 控件，其实还是挺好实现的，那我就直接把代码共享出来，

MainActivity代码：

package com.example.carr.smsspammanager;

import Android.content.BroadcastReceiver;
import android.content.context;
import android.content.intent;
import android.content.IntentFilter;
import android.os.Bundle;
import android.os.environment;
import android.support.v7.APP.AppCompatActivity;
import android.telephony.Smsmessage;
import android.widget.ListView;
import android.widget.toast;

import java.util.ArrayList;
import java.util.List;


public class MainActivity extends AppCompatActivity{

    private ListView lv;
    //private File sdRoot;
    private String body;
    private String address;
    private BATteryBroadcastReceiver batteryBroadcastReceiver;
    private LvAdapter adapter;
    private List<LvBean> lvBeans;

    @Override
    protected void onCreate(Bundle savedinstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.layout_main);
        lv = findViewById(R.id.lv);

        //判断SD卡是否挂载
        if (!Environment.getExternalStorageState().equals(Environment.MEDIA_mountED)){
            toast.maketext(MainActivity.this,"SD卡没有挂载成功，数据将会保存在根目录的Data文件夹",Toast.LENGTH_SHORT).show();
        }
        //sdRoot = Environment.getDataDirectory();
        //Toast.makeText(MainActivity.this,"SD卡数据目录"+sdRoot.toString(),Toast.LENGTH_SHORT).show();
        loadData();

    }

    public void loadData(){
        lvBeans = new ArrayList<LvBean>();
        LvBean currLvBean = new LvBean();
        currLvBean.setPhone("手机号码");
        currLvBean.setbody("拦截的内容");
        lvBeans.add(currLvBean);
        adapter = new LvAdapter(this, lvBeans);
        lv.setAdapter(adapter);
    }

    @Override
    protected void onResume() {
        IntentFilter filter = new IntentFilter();
        filter.addAction("android.provider.Telephony.SMS_RECEIVED");
        batteryBroadcastReceiver = new BatteryBroadcastReceiver();
        registerreceiver(batteryBroadcastReceiver,filter);
        super.onResume();
    }

    @Override
    protected void onpause() {
        unregisterReceiver(batteryBroadcastReceiver);
        super.onPause();
    }

    public class BatteryBroadcastReceiver extends BroadcastReceiver {
        @Override
        public void onreceive(Context context, Intent intent) {
            //int i = 1;
            Bundle bun = intent.getExtras();
            Object[] objs = (Object[]) bun.get("pdus");
            for (Object obj : objs) {
                byte[] pdu = (byte[]) obj;
                SmsMessage msg = SmsMessage.createFromPdu(pdu);
                body = msg.getMessageBody();
                //获取发件人
                address = msg.getOriginatingAddress();
                Toast.makeText(MainActivity.this,"拦截短信："+address,Toast.LENGTH_SHORT).show();
                //如果发件人是15555215554那么就终止广播
                if ("15555215556".equals(address)) {
                    abortBroadcast();
                }
                //i++;
                LvBean mLvBeans = new LvBean();
                mLvBeans.setPhone(address);
                mLvBeans.setBody(body);
                //mLvBeans.setId(i);
                lvBeans.add(mLvBeans);
                adapter.notifydatasetChanged();


            }
        }
    }
}

LvBean类：

package com.example.carr.smsspammanager;

import java.io.File;

/**
 * Created by carr on 2018/1/13.
 */

public class LvBean {

    private String phone;
    private String body;

    private File file;

    public File getFile() {
        return file;
    }

    public void setFile(File file) {
        this.file = file;
    }

    public String getPhone() {
        return phone;
    }

    public void setPhone(String phone) {
        this.phone = phone;
    }

    public String getBody() {
        return body;
    }

    public void setBody(String body) {
        this.body = body;
    }



}

LvAdapter自定义适配器：

package com.example.carr.smsspammanager;

import android.content.Context;
import android.view.LayoutInflater;
import android.view.View;
import android.view.ViewGroup;
import android.widget.BaseAdapter;
import android.widget.TextView;

import java.util.List;

/**
 * Created by carr on 2018/1/13.
 */

public class LvAdapter extends BaseAdapter {

    private List<LvBean> mLvList;
    private LayoutInflater inflater;
    //第一次查找控件的时候把找到的控件加入viewhold中
    ViewHold iv=null;
    public LvAdapter(Context con,List<LvBean> LvBeanList){
        mLvList=LvBeanList;
        inflater=LayoutInflater.from(con);
    }

    @Override
    public int getCount() {
        return mLvList.size();
    }

    @Override
    public LvBean getItem(int i) {
        return mLvList.get(i);
    }

    @Override
    public long getItemId(int i) {
        return i;
    }

    @Override
    public View getView(int i, View view, ViewGroup viewGroup) {
        if (view==null){
            view=inflater.inflate(R.layout.lv_view,null);
            iv=new ViewHold();
            iv.tv_phone = view.findViewById(R.id.tv_phone);
            iv.tv_body = view.findViewById(R.id.tv_body);
            view.setTag(iv);
        }else{
            iv= (ViewHold) view.getTag();
        }
        LvBean lvBean = getItem(i);
        iv.tv_phone.setText(lvBean.getPhone());
        iv.tv_body.setText(lvBean.getBody());
        return view;
    }

    static class ViewHold{
        TextView tv_phone;
        TextView tv_body;
    }
}

大家可以好好的看下代码，也是挺好理解的，实在有不懂的地方也可以私信我。

其实是真的不愿意写注释。
