我已截获来电并在标准屏幕上显示我的活动。在此活动中，我有“接听电话”和“拒绝电话”按钮，但我无法正常工作。

我找到了两种以编程方式接听/拒绝电话的解决方案：

  1. 使用 ITelephony.aidl 但它仅在 api v10 之前有效。所以这是错误的方式

  2. 有以下内容：

    private void acceptCall(Context context) {
  Intent buttonDown = new Intent(Intent.ACTION_MEDIA_BUTTON);
  buttonDown.putExtra(Intent.EXTRA_KEY_EVENT, new KeyEvent(
        KeyEvent.ACTION_UP, KeyEvent.KEYCODE_HEADSETHOOK));
  context.sendOrderedBroadcast(buttonDown,
        "android.permission.CALL_PRIVILEGED");
    // froyo and beyond trigger on buttonUp instead of buttonDown
  Intent buttonUp = new Intent(Intent.ACTION_MEDIA_BUTTON);
  buttonUp.putExtra(Intent.EXTRA_KEY_EVENT, new KeyEvent(
        KeyEvent.ACTION_UP, KeyEvent.KEYCODE_HEADSETHOOK));
  context.sendOrderedBroadcast(buttonUp,
        "android.permission.CALL_PRIVILEGED");
}


private void acceptCall(Context context) {
  Intent buttonDown = new Intent(Intent.ACTION_MEDIA_BUTTON);
  buttonDown.putExtra(Intent.EXTRA_KEY_EVENT, new KeyEvent(
        KeyEvent.ACTION_DOWN, KeyEvent.KEYCODE_HEADSETHOOK));
  context.sendOrderedBroadcast(buttonDown,
        "android.permission.CALL_PRIVILEGED");
  // froyo and beyond trigger on buttonUp instead of buttonDown
  Intent buttonUp = new Intent(Intent.ACTION_MEDIA_BUTTON);
  buttonUp.putExtra(Intent.EXTRA_KEY_EVENT, new KeyEvent(
        KeyEvent.ACTION_UP, KeyEvent.KEYCODE_HEADSETHOOK));
  context.sendOrderedBroadcast(buttonUp,
        "android.permission.CALL_PRIVILEGED");
}

从这里http://www.codeproject.com/Tips/578817/Reject-and-Accept-an-Incoming-Call

然而什么都没有！我单击按钮并相应地调用上面的方法，但没有任何反应。我在几个设备上测试了它，结果是一样的。

嗯，然后我在 samsung nexus one 上回答成功，但在 HTC 上回答不了。拒绝功能对两者都不起作用。

结果我发现了http://androidbridge.blogspot.com/2011/05/how-to-answer-incoming-call-in-android.html

这是适用于 HTC 设备的解决方案：

在 Android 2.3.3 HTC Sensation 中，这段代码不起作用。原因是在 2.3.3 中我发现一个 HeadsetObserver 正在监听实际的蓝牙插件事件。所以你需要发送一个 Intent 假装已经连接了一个耳机。要解决此问题，您需要在调用上述代码之前发送 ACTION_HEADSET_PLUG Intent。

所以我在接受调用代码之前添加了以下代码：

Intent headSetUnPluggedintent = new Intent(Intent.ACTION_HEADSET_PLUG);
 headSetUnPluggedintent.addFlags(Intent.FLAG_RECEIVER_REGISTERED_ONLY);
 headSetUnPluggedintent.putExtra("state", 1); // 0 = unplugged  1 = Headset with microphone 2 = Headset without microphone
 headSetUnPluggedintent.putExtra("name", "Headset");
 // TODO: Should we require a permission?
 sendOrderedBroadcast(headSetUnPluggedintent, null);

所以最终的工作代码是

    private void acceptCall() {
    setHeadSetConnectEmulated();
    Intent buttonUP = new Intent(Intent.ACTION_MEDIA_BUTTON);
    buttonUP.putExtra(Intent.EXTRA_KEY_EVENT, new KeyEvent(KeyEvent.ACTION_UP, KeyEvent.KEYCODE_HEADSETHOOK));
    IncomingCallActivity.this.getApplicationContext().sendOrderedBroadcast(buttonUP, "android.permission.CALL_PRIVILEGED");
}

private void setHeadSetConnectEmulated(){
    Intent headSetUnPluggedintent = new Intent(Intent.ACTION_HEADSET_PLUG);
    headSetUnPluggedintent.addFlags(Intent.FLAG_RECEIVER_REGISTERED_ONLY);
    headSetUnPluggedintent.putExtra("state", 1); // 0 = unplugged  1 = Headset with microphone 2 = Headset without microphone
    headSetUnPluggedintent.putExtra("name", "Headset");
    // TODO: Should we require a permission?
    sendOrderedBroadcast(headSetUnPluggedintent, null);
}

private void rejectCall() {
    Intent buttonDown = new Intent(Intent.ACTION_MEDIA_BUTTON);
    buttonDown.putExtra(Intent.EXTRA_KEY_EVENT, new KeyEvent(KeyEvent.ACTION_DOWN, KeyEvent.KEYCODE_HEADSETHOOK));
    IncomingCallActivity.this.getApplicationContext().sendOrderedBroadcast(buttonDown, "android.permission.CALL_PRIVILEGED");
}

我有同样的问题。按钮向上/向下意图的目的是模仿耳机的回答。如果没有插入耳机，某些手机和android版本会忽略intent。您需要先检查耳机状态（以便可以在事后重置）并发送intent以“插入”耳机。

除了我试图从我创建的应用程序拨打电话外，我遇到了类似的问题。通过将此添加到清单中进行了补救。

 <uses-permission android:name="android.permission.CALL_PHONE" >
</uses-permission>

您可以使用此 Reciver 来取件或拒绝，

public class AutoAnswerIntentService extends BroadcastReceiver {

Context context = null;
private static String mFileName = null;

private static final String TAG = "in reciver";

@Override
public void onReceive(Context context, Intent intent) {
    // Toast.makeText(context, "calling now", Toast.LENGTH_LONG).show();
    if (!intent.getAction().equals("android.intent.action.PHONE_STATE"))
        return;
    else {
        String state = intent.getStringExtra(TelephonyManager.EXTRA_STATE);

        if (state.equals(TelephonyManager.EXTRA_STATE_RINGING)) {
                    if (state.equals(TelephonyManager.EXTRA_STATE_RINGING)) {
        String number = intent
                .getStringExtra(TelephonyManager.EXTRA_INCOMING_NUMBER);
        Log.d(TAG, "Incoming call from: " + number);
        Intent buttonUp = new Intent(Intent.ACTION_MEDIA_BUTTON);
        buttonUp.putExtra(Intent.EXTRA_KEY_EVENT, new KeyEvent(
                KeyEvent.ACTION_UP, KeyEvent.KEYCODE_HEADSETHOOK));
        try {
            context.sendOrderedBroadcast(buttonUp,
                    "android.permission.CALL_PRIVILEGED");
            Log.d(TAG, "ACTION_MEDIA_BUTTON broadcasted...");
            // startRecording();
        } catch (Exception e) {
            Log.d(TAG, "Catch block of ACTION_MEDIA_BUTTON broadcast !");


            return;
        } else if (state.equals(TelephonyManager.EXTRA_STATE_OFFHOOK)) {

            Log.d(TAG, "CALL ANSWERED NOW !!");
            return;
        } else if (state.equals(TelephonyManager.EXTRA_STATE_IDLE)) {
            Log.d(TAG, "ALL DONE IN ELSE IF...... !!");

        } else {
            Log.d(TAG, "ALL DONE IN ELSE ...... !!");

        }
    }
}

并在清单文件中添加此权限 

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