Android实现短信自动回复,挂电话

 简单功能,配置一下ITelephoney,ITelephony这个接口不能直接用的。

需要先在src新建包com.android.internal.telephony,在其中新建一个File,后缀为aidl(它是一种android内部进程通信接口的描述语言,通过它我们可以定义进程间的通信接口),内容如下

package com.android.internal.telephony;  
interface ITelephony{  
boolean endCall();  
void answerRingingCall();  
} 
接下来就是一下MainActivity,垃圾代码如下。
package com.example.autoreply;

import android.os.Bundle;
import android.os.Handler;
import android.app.Activity;
import java.lang.reflect.Method;  
import java.util.HashMap;

public class MainActivity extends Activity {  
                
    Button btn;//退出按钮  
    EditText et;//回复短信的内容编辑框  
    TextView tv;//拦截数量通知的显示  
    
    TelephonyManager tpm;
    SharedPreferences sp; 
    
    int count = 0;//来电总数  
    int peo = 0;//来电的号码个数,跟来电总数有区别,这个不包括重复来电,  
    String num;//存储来电号码
    
    HashMap numMap;//用来存储来电号码  
    
    @Override  
    public void onCreate(Bundle savedInstanceState) {

        setContentView(R.layout.activity_main);  
        getWindow().setFeatureInt(Window.FEATURE_CUSTOM_TITLE,      // 注意顺序   
                R.layout.title);       
        
        tv = (TextView) findViewById(R.id.textView1);  
        et = (EditText) findViewById(R.id.editText1);  
        btn = (Button) findViewById(R.id.button1);  
        
        sp = this.getSharedPreferences("SP", MODE_PRIVATE);

            et.setText(sp.getString("sms", "我现在正在上课,一会儿下课了联系你"));  
        }  
        tpm = (TelephonyManager) this.getSystemService(Context.TELEPHONY_SERVICE);//获取电话通讯服务  
        tpm.listen(new MyPhoneStateListener(),PhoneStateListener.LISTEN_CALL_STATE);//给电话服务增加状态监听器,监听来电,通话,挂断等状态  
      
        btn.setOnClickListener(new OnClickListener() {  
            @Override

            }

                if(!numMap.containsKey(num)){//如果之前没有来电,把这个号码加入已经来电过的列表
