我想实现一个用于接收或发送呼叫和消息的手机号码的应用程序.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
}
});
}@H_403_5@
}
我想我们可能会使用BroadcastReceiver.But我没有更多的知识.它给我一个实现块或un块手机号码的想法.
请任何身体帮助我…..
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 {
@Override
public 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);
}}@H_403_5@
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;
}
@Override
public 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);
}}@H_403_5@
现在在src中创建此包com.android.internal.telephony现在在此包中右键单击 – >新 – >文件现在提供名称ITelephony.aidl并粘贴此代码
package com.android.internal.telephony;
interface ITelephony {
boolean endCall();
void answerRingingCall();
void silenceRinger();
}@H_403_5@
注意：代码在Android 2.2(Froyo),2.3(GingerBread)
