android接听来电 [英] android answer incoming call

问题描述

我拦截了来电并在标准屏幕上显示我的活动。
在这项活动中，我有接听电话和拒绝电话按钮，但我无法正常工作。

I have intercepted incoming call and show my activity over standard screen. On this activity I have buttons "answer call" and "reject call", but I can't do it working.

我找到了两个解决方案接听/拒绝电话programaticaly：

I have found two solutions to answer/reject phone call programaticaly:

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. 以下内容：

1. With ITelephony.aidl but it works only before api v10. So it is wrong way

2. With following:

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 - 并且接受来电

但是没有！我点击按钮并相应调用上面的方法，没有任何反应。
我在几台设备上进行了测试，结果相同。

However nothing! I click buttons and invoke methods above accordingly, and nothing happens. I tested it on several devices, and result the same.

嗯，然后我成功回答了三星nexus one，但没有回复HTC有意义。拒绝功能对两者都不起作用。

Hmm, then I was successful with answering on samsung nexus one, but not on HTC with sense. Reject function doesnt work on both.

推荐答案

结果我找到了 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：

Here is solution which works on HTCs devices:

在Android 2.3.3 HTC Sensation中，这段代码不起作用。原因是在2.3.3我发现HeadsetObserver正在侦听实际的蓝牙插件事件。因此，您需要发送一个Intent假装已经连接了耳机。要解决此问题，您需要在调用上面的代码之前发送ACTION_HEADSET_PLUG Intent。

In Android 2.3.3 HTC Sensation this piece of code does not work. Reason is in 2.3.3 I found a HeadsetObserver listening for actual bluetooth plug-in event. So you need to send a Intent pretending there is a headset connected already. To fix this problem you need to send the ACTION_HEADSET_PLUG Intent before calling the above code.

所以我在接受调用代码之前添加了以下代码：

So I added following code before accept call code:

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");
}
