如何在Android 2.3.3中拒绝/接听电话？

Question

我想在android 2.3.3中拒绝/接听电话。我尝试使用ITelephony - endcall()和answerRingingCall()但没有成功。有什么想法吗？

Answer 1

如何接听来电：

/**
 * Emulates a headset button press to accept the call
 * 
 * @param context
 *            A context to use
 */
public static void answerPhoneHeadsethook(Context context) {
    // Simulate a press of the headset button to pick up the call
    // SettingsClass.logMe(tag, "Simulating headset button");
    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");
}

就我而言，没有办法拒绝2.3+中的电话（可以用上面的方法接受和拒绝来电，但是然后来电者必须付钱）。

需要在!!之前发送此意图

Intent headSetUnPluggedintent = new Intent(Intent.ACTION_HEADSET_PLUG);
              headSetUnPluggedintent.addFlags(Intent.FLAG_RECEIVER_REGISTERED_ONLY);
              headSetUnPluggedintent.putExtra("state", 1);
              headSetUnPluggedintent.putExtra("name", "Headset");

              // TODO: Should we require a permission?
             sendOrderedBroadcast(headSetUnPluggedintent, null);
