MTK-Android13-Dialer 通话界面定制修改

定制通话界面

---

前言-需求

Android中打电话的应用是Dialer,部分商用的场景比如：电话亭、公司共用电话、校园共用电话场景是由一定的定制场景的。

具体需求如下：把通话界面的所有功能按钮全部去掉

备注：

• Dialer 源码分析比较少、定制比较少，可以借鉴下 针对自己的需求看看源码
• 参考资料仅给一下思考，还是得根据自己AOSP 源码查看具体代码，根据架构、层次、业务进行修改！

二、修改文件-实现方案

修改文件

vendor/mediatek/proprietary/packages/apps/Dialer/java/com/android/incallui/incall/impl/InCallFragment.java

修改思路

打开通话界面进行电话时候，查看日志如下，找到对应的源码 InCallFragment

实现方案

在InCallFragment 中屏蔽掉动态添加的组件和相关id 获取判断逻辑即可

isSupportedButton 方法去掉id 判断

 private static boolean isSupportedButton(@InCallButtonIds int id) {return//        id == InCallButtonIds.BUTTON_AUDIO//     || id == InCallButtonIds.BUTTON_MUTE//    || id == InCallButtonIds.BUTTON_DIALPAD// id == InCallButtonIds.BUTTON_HOLDid == InCallButtonIds.BUTTON_SWAP//     || id == InCallButtonIds.BUTTON_UPGRADE_TO_VIDEO//     || id == InCallButtonIds.BUTTON_ADD_CALL|| id == InCallButtonIds.BUTTON_MERGE|| id == InCallButtonIds.BUTTON_MANAGE_VOICE_CONFERENCE|| id == InCallButtonIds.BUTTON_SWAP_SIM|| id == InCallButtonIds.BUTTON_UPGRADE_TO_RTT/// M: [Voice Record]//    || id == InCallButtonIds.BUTTON_SWITCH_VOICE_RECORD/// M: [Hang Up]|| id == InCallButtonIds.BUTTON_HANG_UP_ALL|| id == InCallButtonIds.BUTTON_HANG_UP_HOLD/// M: [ECT(blind)]|| id == InCallButtonIds.BUTTON_ECT|| id == InCallButtonIds.BUTTON_BLIND_ECT/// M: [One way video]|| id == InCallButtonIds.BUTTON_ONE_WAY_VIDEO/// M: ALPS03949921, add switch_to_secondary to enable and disable.|| id == InCallButtonIds.BUTTON_SWITCH_TO_SECONDARY;}

onViewCreated 方法中去掉需要添加的UI组件

@Overridepublic void onViewCreated(@NonNull View view, @Nullable Bundle bundle) {LogUtil.i("InCallFragment.onViewCreated", null);super.onViewCreated(view, bundle);/// M: [Voice Record] Add for recording. @{initVoiceRecorderIcon(view);/// @}inCallScreenDelegate =FragmentUtils.getParent(this, InCallScreenDelegateFactory.class).newInCallScreenDelegate();Assert.isNotNull(inCallScreenDelegate);//  buttonControllers.add(new ButtonController.MuteButtonController(inCallButtonUiDelegate));//  buttonControllers.add(new ButtonController.SpeakerButtonController(inCallButtonUiDelegate));//  buttonControllers.add(new ButtonController.DialpadButtonController(inCallButtonUiDelegate));//  buttonControllers.add(new ButtonController.HoldButtonController(inCallButtonUiDelegate));//    buttonControllers.add(new ButtonController.AddCallButtonController(inCallButtonUiDelegate));buttonControllers.add(new ButtonController.SwapButtonController(inCallButtonUiDelegate));buttonControllers.add(new ButtonController.MergeButtonController(inCallButtonUiDelegate));buttonControllers.add(new ButtonController.SwapSimButtonController(inCallButtonUiDelegate));/*  buttonControllers.add(new ButtonController.UpgradeToVideoButtonController(inCallButtonUiDelegate));*/buttonControllers.add(new UpgradeToRttButtonController(inCallButtonUiDelegate));buttonControllers.add(new ButtonController.ManageConferenceButtonController(inCallScreenDelegate));buttonControllers.add(new ButtonController.SwitchToSecondaryButtonController(inCallScreenDelegate));/// M: [Voice Record] @{/*  buttonControllers.add(new ButtonController.SwitchVoiceRecordButtonController(inCallButtonUiDelegate));*//// @}/// M: [Hang Up] @{buttonControllers.add(new ButtonController.HangupAllButtonController(inCallScreenDelegate));buttonControllers.add(new ButtonController.HangupHoldButtonController(inCallScreenDelegate));/// @}/// M: [ECT(blind)] @{buttonControllers.add(new ButtonController.ECTButtonController(inCallButtonUiDelegate));buttonControllers.add(new ButtonController.BlindECTButtonController(inCallButtonUiDelegate));/// @}/// M: [One way video] @{buttonControllers.add(new ButtonController.UpgradeToOneWayVideoButtonController(inCallButtonUiDelegate));/// @}inCallScreenDelegate.onInCallScreenDelegateInit(this);inCallScreenDelegate.onInCallScreenReady();}

onInCallScreenDialpadVisibilityChange 方法屏蔽组件BUTTON_DIALPAD

 @Overridepublic void onInCallScreenDialpadVisibilityChange(boolean isShowing) {LogUtil.i("InCallFragment.onInCallScreenDialpadVisibilityChange", "isShowing: " + isShowing);// Take note that the dialpad button isShowing//  getButtonController(InCallButtonIds.BUTTON_DIALPAD).setChecked(isShowing);// This check is needed because there is a race condition where we attempt to update// ButtonGridFragment before it is ready, so we check whether it is ready first and once it is// ready, #onButtonGridCreated will mark the dialpad button as isShowing.if (inCallButtonGridFragment != null) {// Update the Android Button's state to isShowing.inCallButtonGridFragment.onInCallScreenDialpadVisibilityChange(isShowing);}Activity activity = getActivity();Window window = activity.getWindow();window.setNavigationBarColor(activity.getColor(isShowing ? android.R.color.background_dark : android.R.color.transparent));}

setHold 方法屏蔽掉需要屏蔽的组件操作BUTTON_HOLD 逻辑

  @Overridepublic void setHold(boolean value) {// getButtonController(InCallButtonIds.BUTTON_HOLD).setChecked(value);}

setAudioState 去除静音和免提相关功能业务

@Overridepublic void setAudioState(CallAudioState audioState) {/// M: do not show bluetooth device information. @{/// Google code: LogUtil.i("InCallFragment.setAudioState", "audioState: " + audioState);LogUtil.i("InCallFragment.setAudioState", "isMuted: " + audioState.isMuted() + ", route: "+ CallAudioState.audioRouteToString(audioState.getRoute()) + ", supportMask: "+ CallAudioState.audioRouteToString(audioState.getSupportedRouteMask()));/// @}/// M: ALPS05941240 AudioRouteSelectorDialogFragment would not dismiss when call/// audio state changed. @{AudioRouteSelectorDialogFragment audioRouteSelectorDialog =(AudioRouteSelectorDialogFragment) this.getChildFragmentManager().findFragmentByTag(TAG_AUDIOROUTE_SELECTOR_FRAGMENT);if (audioRouteSelectorDialog != null) {audioRouteSelectorDialog.dismissAllowingStateLoss();audioRouteSelectorDialog = null;}/// @}/*  ((SpeakerButtonController) getButtonController(InCallButtonIds.BUTTON_AUDIO)).setAudioState(audioState);*///   getButtonController(InCallButtonIds.BUTTON_MUTE).setChecked(audioState.isMuted());}

updateRecordStateUi 去除录音相关业务

 /*** M: [Voice Record] updateRecordStateUi* @param isRecording*/@Overridepublic void updateRecordStateUi(boolean isRecording) {LogUtil.d("InCallFragment.updateRecordStateUi", "[updateRecordStateUi]... " + isRecording);DialerCall ringCall = CallList.getInstance().getIncomingCall();if (isRecording && (ringCall == null)) {updateVoiceRecordIcon(true);} else {updateVoiceRecordIcon(false);}//   getButtonController(InCallButtonIds.BUTTON_SWITCH_VOICE_RECORD).setChecked(isRecording);}

三、源码分析

InCallFragment 分析

看源码 如下：

/** Fragment that shows UI for an ongoing voice call. */
public class InCallFragment extends Fragmentimplements InCallScreen,InCallButtonUi,OnClickListener,AudioRouteSelectorPresenter,OnButtonGridCreatedListener {....}

看类定义，它本质上就是一个通话界面的UI，直接集成了Fragment 组件。所以它就是一个显示UI组件并具备生命周期

ButtonController 源码分析

看类定义,原来它就是一个接口，管理Button用的。

/** Manages a single button. */
interface ButtonController {
............
}

那为什么会分析到这里，一方面它从直观上来看，就是管理Button的，再具体看看源码：

• 定义了所有的功能Button
• 对每个自定义功能Button 描述和定义，都有相关的String/Id

所以，当我们找到这里时候就提供了解决需求的思路，一步一步去解决实际需求和阅读相关源码。

总结

• 这个需求其实很简单的，通过阅读源码并分析源码能够快速实现需求
• 这里面比较坑的是，其实部分按钮咋一看和实际ID 很难对上，本身也不熟悉情况下导致修改错误，建议一个一个或者再无编译报错情况下一个一个验证。
• 初识Dialer 界面源码和部分业务逻辑，实际项目中其实还涉及到在原生APP基础上定制这个UI界面，这样就需要了解这个源码并针对性修改了。
