如何在Android应用程序开发中阻止手机号码呼叫和消息接收？

概述我想实现一个用于阻止移动号码的应用程序,用于接收或发送呼叫和消息.在我的应用程序中,我在EditText框中输入手机号码然后我点击一个按钮来阻止用户输入的手机号码.我已经实现了一个活动类,如下所示：publicclassBlockNumberActivityextendsActivity{/**Calledwhenth

我想实现一个用于阻止移动号码的应用程序,用于接收或发送呼叫和消息.在我的应用程序中,我在EditText框中输入手机号码然后我点击一个按钮来阻止用户输入的手机号码.

我已经实现了一个活动类,如下所示：

public class BlockNumberActivity extends Activity {    /** Called when the activity is first created. */    @OverrIDe    public voID onCreate(Bundle savedInstanceState) {        super.onCreate(savedInstanceState);        setContentVIEw(R.layout.main);        ((button)findVIEwByID(R.ID.block)).setonClickListener(new OnClickListener() {            @OverrIDe            public voID onClick(VIEw v) {                String mobileNumer = ((EditText)findVIEwByID(R.ID.mobileNum)).getText().toString();                //How to block entered mobileNumber            }        });        ((button)findVIEwByID(R.ID.unblock)).setonClickListener(new OnClickListener() {            @OverrIDe            public voID onClick(VIEw v) {                String mobileNumer = ((EditText)findVIEwByID(R.ID.mobileNum)).getText().toString();                //How to unblock entered mobileNumber            }        });    }}

我想我们可以使用broadcastReceiver.但我对它没有更多的了解.请告诉我如何实现阻止或解锁移动号码.
请任何人帮我…..

解决方法:

创建Phonecallreceiver .java

import androID.content.broadcastReceiver;import androID.content.Context;import androID.content.Intent;import androID.telephony.PhonestateListener;import androID.telephony.TelephonyManager;import androID.util.Log;import androID.Widget.Toast;public class Phonecallreceiver extends broadcastReceiver {  @OverrIDepublic voID onReceive(Context context, Intent intent) {     TelephonyManager telephony = (TelephonyManager) context.getSystemService(Context.TELEPHONY_SERVICE);    PhoneCallStateListener customPhoneListener = new PhoneCallStateListener(context);    telephony.Listen(customPhoneListener, PhonestateListener.ListEN_CALL_STATE);}}

现在创建PhoneCallStateListener .java

import java.lang.reflect.Method;import androID.content.Context;import androID.content.Intent;import androID.content.SharedPreferences;import androID.media.AudioManager;import androID.os.Bundle;import androID.preference.PreferenceManager;import androID.telephony.PhonestateListener;import androID.telephony.TelephonyManager;import androID.Widget.Toast;import com.androID.internal.telephony.ITelephony;public class PhoneCallStateListener extends PhonestateListener {    private Context context;public PhoneCallStateListener(Context context){    this.context = context;}@OverrIDepublic voID onCallStateChanged(int state, String incomingNumber) {      SharedPreferences prefs=PreferenceManager.getDefaultSharedPreferences(context);    switch (state) {        case TelephonyManager.CALL_STATE_RINGING:                     String block_number = prefs.getString("block_number", null);            AudioManager audioManager = (AudioManager) context.getSystemService(Context.AUdio_SERVICE);             //Turn ON the mute            audioManager.setStreamMute(AudioManager.STREAM_RING, true);                             TelephonyManager telephonyManager = (TelephonyManager) context.getSystemService(Context.TELEPHONY_SERVICE);            try {                Toast.makeText(context, "in"+block_number, Toast.LENGTH_LONG).show();                Class clazz = Class.forname(telephonyManager.getClass().getname());                Method method = clazz.getDeclaredMethod("getITelephony");                method.setAccessible(true);                ITelephony telephonyService = (ITelephony) method.invoke(telephonyManager);                     //Checking incoming call number                System.out.println("Call "+block_number);                if (incomingNumber.equalsIgnoreCase("+91"+block_number)) {                    //telephonyService.silenceRinger();//Security exception problem                     telephonyService = (ITelephony) method.invoke(telephonyManager);                     telephonyService.silenceRinger();                    System.out.println(" in  "+block_number);                    telephonyService.endCall();                }            } catch (Exception e) {                Toast.makeText(context, e.toString(), Toast.LENGTH_LONG).show();            }            //Turn OFF the mute                 audioManager.setStreamMute(AudioManager.STREAM_RING, false);            break;        case PhonestateListener.ListEN_CALL_STATE:    }    super.onCallStateChanged(state, incomingNumber);}}

现在在src中创建此包com.androID.internal.telephony现在在此包中右键单击 – >新 – >文件现在命名为ITelephony.aIDl并粘贴此代码

package com.androID.internal.telephony; interface ITelephony {        boolean endCall();       voID answerRingingCall();        voID silenceRinger(); }

注意：代码在AndroID 2.2(Froyo),2.3(GingerBread)中进行测试
