Android 自动接听电话

1. android 2.3以下版本（不包括2.3）

中的“二 android低版本自动接听/挂断实现”

核心代码：

Class<TelephonyManager> c = TelephonyManager.class;     try {Method getITelephonyMethod = c.getDeclaredMethod("getITelephony", (Class[]) null);getITelephonyMethod.setAccessible(true);ITelephony iTelephony = null;iTelephony = (ITelephony) getITelephonyMethod.invoke(telephonyManager, (Object[]) null);iTelephony.endCall();} catch (Exception e) {Log.e(TAG, "Fail to accept call.", e);}

或

Class<TelephonyManager> c = TelephonyManager.class;           try {Method method = Class.forName("android.os.ServiceManager").getMethod("getService", String.class);                IBinder binder = (IBinder) method.invoke(null, new Object[]{TELEPHONY_SERVICE});                ITelephony telephony = ITelephony.Stub.asInterface(binder);                telephony.answerRingingCall();}catch (Exception e) {                Log.e(TAG, "Fail to accept call.", e);}

没有2.3版本以下的手机，没有测试。

2. android 2.3版本

（1）不使用耳机

private void answerRingingCall() {         //插耳机           Intent localIntent1 = new Intent(Intent.ACTION_HEADSET_PLUG);           localIntent1.addFlags(Intent.FLAG_ACTIVITY_NO_HISTORY);           localIntent1.putExtra("state", 1);           localIntent1.putExtra("microphone", 1);           localIntent1.putExtra("name", "Headset");           sendOrderedBroadcast(localIntent1,"android.permission.CALL_PRIVILEGED");        //按下耳机按钮           Intent localIntent2 = new Intent(Intent.ACTION_MEDIA_BUTTON);           KeyEvent localKeyEvent1 = new KeyEvent(KeyEvent.ACTION_DOWN,KeyEvent.KEYCODE_HEADSETHOOK);           localIntent2.putExtra("android.intent.extra.KEY_EVENT", localKeyEvent1);           sendOrderedBroadcast(localIntent2,"android.permission.CALL_PRIVILEGED");        //放开耳机按钮           Intent localIntent3 = new Intent(Intent.ACTION_MEDIA_BUTTON);           KeyEvent localKeyEvent2 = new KeyEvent(KeyEvent.ACTION_UP,KeyEvent.KEYCODE_HEADSETHOOK);           localIntent3.putExtra("android.intent.extra.KEY_EVENT", localKeyEvent2);           sendOrderedBroadcast(localIntent3, "android.permission.CALL_PRIVILEGED");        //拔出耳机           Intent localIntent4 = new Intent(Intent.ACTION_HEADSET_PLUG);           localIntent4.addFlags(Intent.FLAG_ACTIVITY_NO_HISTORY);           localIntent4.putExtra("state", 0);           localIntent4.putExtra("microphone", 1);           localIntent4.putExtra("name", "Headset");           sendOrderedBroadcast(localIntent4,"android.permission.CALL_PRIVILEGED");    }

（2）需使用耳机（在网上很多人提供了这个方案，所以在这里贴出来）

private void answerRingingCall() {         //按下耳机按钮           Intent localIntent2 = new Intent(Intent.ACTION_MEDIA_BUTTON);           KeyEvent localKeyEvent1 = new KeyEvent(KeyEvent.ACTION_DOWN,KeyEvent.KEYCODE_HEADSETHOOK);           localIntent2.putExtra("android.intent.extra.KEY_EVENT",localKeyEvent1);           sendOrderedBroadcast(localIntent2,"android.permission.CALL_PRIVILEGED");        //放开耳机按钮           Intent localIntent3 = new Intent(Intent.ACTION_MEDIA_BUTTON);           KeyEvent localKeyEvent2 = new KeyEvent(KeyEvent.ACTION_UP,KeyEvent.KEYCODE_HEADSETHOOK);           localIntent3.putExtra("android.intent.extra.KEY_EVENT",localKeyEvent2);           sendOrderedBroadcast(localIntent3,"android.permission.CALL_PRIVILEGED");    }

3. android 4.1， 4.2 版本

更高版本的没有相关机器测试。

从http://blog.sina.com.cn/s/blog_6dc1188a010176cy.html获得的方案

（1）不使用耳机

private void answerRingingCall() {      //放开耳机按钮        Intent localIntent3 = new Intent(Intent.ACTION_MEDIA_BUTTON);        KeyEvent localKeyEvent2 = new KeyEvent(KeyEvent.ACTION_UP,KeyEvent.KEYCODE_HEADSETHOOK);        localIntent3.putExtra("android.intent.extra.KEY_EVENT",localKeyEvent2);        sendOrderedBroadcast(localIntent3,"android.permission.CALL_PRIVILEGED");                //插耳机           Intent localIntent1 = new Intent(Intent.ACTION_HEADSET_PLUG);           localIntent1.addFlags(Intent.FLAG_ACTIVITY_NO_HISTORY);           localIntent1.putExtra("state", 1);           localIntent1.putExtra("microphone", 1);           localIntent1.putExtra("name", "Headset");           sendOrderedBroadcast(localIntent1,"android.permission.CALL_PRIVILEGED");        //按下耳机按钮           Intent localIntent2 = new Intent(Intent.ACTION_MEDIA_BUTTON);           KeyEvent localKeyEvent1 = new KeyEvent(KeyEvent.ACTION_DOWN,KeyEvent.KEYCODE_HEADSETHOOK);           localIntent2.putExtra("android.intent.extra.KEY_EVENT",localKeyEvent1);           sendOrderedBroadcast(localIntent2,"android.permission.CALL_PRIVILEGED");        //放开耳机按钮            localIntent3 = new Intent(Intent.ACTION_MEDIA_BUTTON);            localKeyEvent2 = new KeyEvent(KeyEvent.ACTION_UP,KeyEvent.KEYCODE_HEADSETHOOK);           localIntent3.putExtra("android.intent.extra.KEY_EVENT",localKeyEvent2);           sendOrderedBroadcast(localIntent3,"android.permission.CALL_PRIVILEGED");        //拔出耳机           Intent localIntent4 = new Intent(Intent.ACTION_HEADSET_PLUG);           localIntent4.addFlags(Intent.FLAG_ACTIVITY_NO_HISTORY);           localIntent4.putExtra("state", 0);           localIntent4.putExtra("microphone", 1);           localIntent4.putExtra("name", "Headset");           sendOrderedBroadcast(localIntent4,"android.permission.CALL_PRIVILEGED");    }

（2）使用耳机同上面的2（2）
