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
}
});
}
}
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);
}}
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); }}
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();
}
注意：代码在Android 2.2(Froyo),2.3(GingerBread)
