默认情况下，来电android是以通知窗口的形式显示，只在屏幕的顶部弹出一个悬浮通知，现在改为全屏显示，直接跳转来电界面InCallActivity
\packages\apps\Dialer\java\com\android\incallui\StatusBarNotifier.java
/**
* Helper method for updateInCallNotification() and updateNotification(): Update the phone app's
* status bar notification based on the current telephony state, or cancels the notification if
* the phone is totally idle.
*/
private boolean firstShow = true;//add
@RequiresPermission(Manifest.permission.READ_PHONE_STATE)
private void updateInCallNotification() {
LogUtil.d("StatusBarNotifier.updateInCallNotification", "");
final DialerCall call = getCallToShow(CallList.getInstance());
// don't show Notification, if call has already been rejected
if (call != null && !call.isRejected()) {
// add 当去电或者来电是会一直重复调用这个方法,要做一个判断，防止重复进入InCallActivity
showNotification(call);
if (firstShow) {
context.startActivity(InCallActivity.getIntent(context, false/*showDialpad*/, false/*newOutgoingCall*/, true /* forFullScreen */));
firstShow = false;
}
//add end
} else {
firstShow = true;//add
cancelNotification();
}
}
Android 11 通知是否弹出，有两个因素决定，
一个是通知的优先级（setPriority(NotificationCompat.PRIORITY_MIN)），
另一个是通知渠道（通道）的优先级（NotificationManager.IMPORTANCE_HIGH）
public NotificationChannel(String id, CharSequence name, @Importance int importance) {
this.mId = getTrimmedString(id);
this.mName = name != null ? getTrimmedString(name.toString()) : null;
this.mImportance = importance;
}
\packages\apps\Dialer\java\com\android\dialer\notification\NotificationChannelManager.java
这是通话app 为通知渠道的管理和创建
private static void createIncomingCallChannel(@NonNull Context context) {
NotificationChannel channel =
new NotificationChannel(
NotificationChannelId.INCOMING_CALL,
context.getText(R.string.notification_channel_incoming_call),
NotificationManager.IMPORTANCE_MAX);
......
}
实际修改 :来电通知弹出悬浮
/** Sets up the main Ui for the notification */
@RequiresPermission(Manifest.permission.READ_PHONE_STATE)
private void buildAndSendNotification(CallList callList, DialerCall originalCall, ContactCacheEntry contactInfo) {
...........
switch (notificationType) {
case NOTIFICATION_INCOMING_CALL:
if (BuildCompat.isAtLeastO()) {
builder.setChannelId(NotificationChannelId.ONGOING_CALL);// add old -> NotificationChannelId.INCOMING_CALL
}
......
}
break;
case NOTIFICATION_INCOMING_CALL_QUIET:
if (BuildCompat.isAtLeastO()) {
builder.setChannelId(NotificationChannelId.ONGOING_CALL);
}
break;
............
}
按钮接听方式
修改位置
packages\apps\Dialer\java\com\android\incallui\answer\impl\answermethod\AnswerMethodFactory.java
@NonNull
public static AnswerMethod createAnswerMethod(@NonNull Activity activity) {
if (needTwoButton(activity)) {
return new TwoButtonMethod();
} else {
//return new FlingUpDownMethod();
return new TwoButtonMethod();//add
}
}
其实通知和SystemUI 相关，也可以在它哪里拦截！！！
SystemIU关于悬浮通知

在Frameworks层拦截Home键
