插入sim卡弹出密码锁定窗口过程

如图，开了pin码的sim卡插入手机后会弹出要输入pin码的锁定窗口
在这里插入图片描述

这个Android 12中大致的过程可以从logcat的打印看出一些
在这里插入图片描述
这个界面主要由2个部分组成，上部分KeyguardMessageArea, 下部分KeyguardSimPinView

顶部文本显示定制

在这里插入图片描述

“请输入 SIM 1 PIN，您还可尝试3次”这个文本显示与下方的pin码输入窗口不是一个窗口，是分开控制的。通过搜索上面的中文提示文本，对应的UI或代码

frameworks/base/packages/SystemUI/res-unisoc/values-zh-rCN/strings_ex.xml

    <plurals name="kg_password_wrong_pin_code_multi"><item quantity="one">SIM <xliff:g id="carrier" example="CARD 1">%1$s</xliff:g> PIN 码不正确，您还有 <xliff:g id="number">%2$d</xliff:g> 次尝试机会。如果仍不正确，则需要联系运营商帮您解锁设备。</item><item quantity="other">SIM <xliff:g id="carrier" example="CARD 1">%1$s</xliff:g> PIN 码不正确，您还有 <xliff:g id="number">%2$d</xliff:g> 次尝试机会。</item></plurals><plurals name="kg_password_default_pin_message_multi"><item quantity="one">请输入 SIM <xliff:g id="carrier" example="CARD 1">%1$s</xliff:g> PIN，您还可以尝试 <xliff:g id="number">%2$d</xliff:g> 次。如果仍不正确，则需要联系运营商帮您解锁设备。</item><item quantity="other">请输入 SIM <xliff:g id="carrier" example="CARD 1">%1$s</xliff:g> PIN，您还可以尝试 <xliff:g id="number">%2$d</xliff:g> 次。</item></plurals>

默认显示在最顶端的是这个kg_password_default_pin_message_multi

其是在
frameworks/base/packages/SystemUI/src/com/android/keyguard/KeyguardSimPinViewController.java
中控制显示的,
动态变化sim卡输入还剩的次数的文本由以下函数返回

    private String getPinPasswordErrorMessage(int attemptsRemaining, boolean isDefault) {String displayMessage;int msgId;if (attemptsRemaining == 0) {displayMessage = mView.getResources().getString(R.string.kg_password_wrong_pin_code_pukked);} else if (attemptsRemaining > 0) {int count = TelephonyManager.getDefault().getSimCount();if (count < 2) {msgId = isDefault ? R.plurals.kg_password_default_pin_message :R.plurals.kg_password_wrong_pin_code;displayMessage = mView.getResources().getQuantityString(msgId, attemptsRemaining, attemptsRemaining);} else {msgId = isDefault ? R.plurals.kg_password_default_pin_message_multi :R.plurals.kg_password_wrong_pin_code_multi;int phoneId = SubscriptionManager.getPhoneId(mSubId);SubscriptionInfo info = mKeyguardUpdateMonitor.getSubscriptionInfoForSubId(mSubId);Log.d(LOG_TAG, "phoneId : " + phoneId + "; mSubId : " + mSubId + "; info : " + info);if (info!= null && !SubscriptionManager.isValidPhoneId(phoneId)) {phoneId = info.getSimSlotIndex();Log.d(LOG_TAG, "SubscriptionInfo:"+info.toString() + "; phoneId : " + phoneId);}displayMessage = mView.getResources().getQuantityString(msgId,attemptsRemaining, phoneId + 1, attemptsRemaining);}} else {msgId = isDefault ? R.string.kg_sim_pin_instructions : R.string.kg_password_pin_failed;displayMessage = mView.getResources().getString(msgId);}if (KeyguardEsimArea.isEsimLocked(mView.getContext(), mSubId)) {displayMessage = mView.getResources().getString(R.string.kg_sim_lock_esim_instructions, displayMessage);}if (DEBUG) {Log.d(LOG_TAG, "getPinPasswordErrorMessage: attemptsRemaining="+ attemptsRemaining + " displayMessage=" + displayMessage);}return displayMessage;}

此文本是由mMessageAreaController通过调用sendMessage来显示的

mMessageAreaController.setMessage(getPinPasswordErrorMessage(result.getAttemptsRemaining(), false));

mMessageAreaController的创建

KeyguardPatternViewController.java:206:        mMessageAreaControllerFactory = messageAreaControllerFactory;
KeyguardPatternViewController.java:208:        mMessageAreaController = mMessageAreaControllerFactory.create(kma);KeyguardAbsKeyInputViewController.java:91:        mMessageAreaController = messageAreaControllerFactory.create(kma);
KeyguardAbsKeyInputViewController.java:99:        mMessageAreaController.init();
KeyguardAbsKeyInputViewController.java:144:        mMessageAreaController.reloadColors();

    protected KeyguardPatternViewController(KeyguardPatternView view,KeyguardUpdateMonitor keyguardUpdateMonitor,SecurityMode securityMode,LockPatternUtils lockPatternUtils,KeyguardSecurityCallback keyguardSecurityCallback,LatencyTracker latencyTracker,FalsingCollector falsingCollector,EmergencyButtonController emergencyButtonController,KeyguardMessageAreaController.Factory messageAreaControllerFactory) {super(view, securityMode, keyguardSecurityCallback, emergencyButtonController);mKeyguardUpdateMonitor = keyguardUpdateMonitor;mLockPatternUtils = lockPatternUtils;mLatencyTracker = latencyTracker;mFalsingCollector = falsingCollector;mEmergencyButtonController = emergencyButtonController;mMessageAreaControllerFactory = messageAreaControllerFactory;KeyguardMessageArea kma = KeyguardMessageArea.findSecurityMessageDisplay(mView);mMessageAreaController = mMessageAreaControllerFactory.create(kma);mLockPatternView = mView.findViewById(R.id.lockPatternView);}

    protected KeyguardAbsKeyInputViewController(T view,KeyguardUpdateMonitor keyguardUpdateMonitor,SecurityMode securityMode,LockPatternUtils lockPatternUtils,KeyguardSecurityCallback keyguardSecurityCallback,KeyguardMessageAreaController.Factory messageAreaControllerFactory,LatencyTracker latencyTracker, FalsingCollector falsingCollector,EmergencyButtonController emergencyButtonController) {super(view, securityMode, keyguardSecurityCallback, emergencyButtonController);mKeyguardUpdateMonitor = keyguardUpdateMonitor;mLockPatternUtils = lockPatternUtils;mLatencyTracker = latencyTracker;mFalsingCollector = falsingCollector;mEmergencyButtonController = emergencyButtonController;KeyguardMessageArea kma = KeyguardMessageArea.findSecurityMessageDisplay(mView);mMessageAreaController = messageAreaControllerFactory.create(kma);}

这个显示区域KeyguardMessageArea是由findSecurityMessageDisplay创建的
frameworks/base/packages/SystemUI/src/com/android/keyguard/KeyguardMessageArea.java

    public static KeyguardMessageArea findSecurityMessageDisplay(View v) {KeyguardMessageArea messageArea = v.findViewById(R.id.keyguard_message_area);if (messageArea == null) {messageArea = v.getRootView().findViewById(R.id.keyguard_message_area);}if (messageArea == null) {throw new RuntimeException("Can't find keyguard_message_area in " + v.getClass());}return messageArea;}

由此定位到xml中的id: R.id.keyguard_message_area

安卓12中，密码输入框与顶部文本KeyguardMessageArea是两块UI
如下修改可以隐藏掉顶部文本区域，让密码输入框最大化

diff --git a/frameworks/base/packages/SystemUI/res-keyguard/values/dimens.xml b/frameworks/base/packages/SystemUI/res-keyguard/values/dimens.xml

修改密码按键背景与样式

在这里插入图片描述

frameworks/base/packages/SystemUI/res-keyguard/drawable/num_pad_key_background.xml

<ripplexmlns:android="http://schemas.android.com/apk/res/android"android:color="?android:attr/colorControlHighlight"><item android:id="@+id/background"><shape><solid android:color="?android:attr/colorControlNormal" /><corners android:radius="10dp" /></shape></item>
</ripple>

其中color可以修改背景色，radius修改圆角。

密码按键文本颜色修改
frameworks/base/packages/SystemUI/src/com/android/keyguard/NumPadKey.java

    public void reloadColors() {int textColor = Utils.getColorAttr(getContext(), android.R.attr.textColorPrimary).getDefaultColor();int klondikeColor = Utils.getColorAttr(getContext(), android.R.attr.textColorSecondary).getDefaultColor();mDigitText.setTextColor(textColor);mKlondikeText.setTextColor(klondikeColor);if (mAnimator != null) mAnimator.reloadColors(getContext());}

密码输入框样式

frameworks/base/packages/SystemUI/src/com/android/keyguard/PasswordTextView.java
文本颜色

    /*** Reload colors from resources.**/public void reloadColors() {/*int textColor = Utils.getColorAttr(getContext(), android.R.attr.textColorPrimary).getDefaultColor();mDrawPaint.setColor(textColor);*/mDrawPaint.setColor(Color.WHITE);}

结合
frameworks/base/packages/SystemUI/res-keyguard/layout/keyguard_sim_pin_view.xml
frameworks/base/packages/SystemUI/res-keyguard/layout/keyguard_sim_puk_view.xml
中的PasswordTextView进行修改

            <com.android.keyguard.PasswordTextViewandroid:id="@+id/simPinEntry"android:layout_width="match_parent"android:layout_height="@dimen/keyguard_password_height"android:gravity="center"android:layout_alignParentStart="true"androidprv:scaledTextSize="@integer/scaled_password_text_size"android:contentDescription="@string/keyguard_accessibility_sim_pin_area"/>

屏敝“正在解锁 SIM卡”的提示

PIN码输入正确时，会弹一个几秒的文本提示“正在解锁 SIM 卡”

frameworks/base/packages/SystemUI$ grep -nr "正在解锁"
res-keyguard/values-zh-rCN/strings.xml:52:    <string name="keyguard_sim_unlock_progress_dialog_message" msgid="2394023844117630429">"正在解锁 SIM 卡…"</string>
res-keyguard/values-zh-rCN/strings.xml:81:    <string name="kg_sim_unlock_progress_dialog_message" msgid="4251352015304070326">"正在解锁 SIM 卡…"</string>

src/com/android/keyguard/KeyguardSimPukViewController.java:202:                    msg = com.android.systemui.R.string.keyguard_sim_unlock_progress_dialog_message;src/com/android/keyguard/KeyguardSimPukViewController.java:442:                    mView.getResources().getString(R.string.kg_sim_unlock_progress_dialog_message));
src/com/android/keyguard/KeyguardSimPinViewController.java:279:                    mView.getResources().getString(R.string.kg_sim_unlock_progress_dialog_message));src-unisoc/com/unisoc/keyguard/KeyguardSimLockViewController.java:339:                    mView.getContext().getString(R.string.kg_sim_unlock_progress_dialog_message));

解锁PIN码对应源码为
frameworks/base/packages/SystemUI/src/com/android/keyguard/KeyguardSimPinViewController.java
其显示的对应框是由getSimUnlockProgressDialog返回的

    private Dialog getSimUnlockProgressDialog() {if (mSimUnlockProgressDialog == null) {mSimUnlockProgressDialog = new ProgressDialog(mView.getContext());mSimUnlockProgressDialog.setMessage(mView.getResources().getString(R.string.kg_sim_unlock_progress_dialog_message));mSimUnlockProgressDialog.setIndeterminate(true);mSimUnlockProgressDialog.setCancelable(false);mSimUnlockProgressDialog.getWindow().setType(WindowManager.LayoutParams.TYPE_KEYGUARD_DIALOG);}return mSimUnlockProgressDialog;}

如下图，通过getSimUnlockProgressDialog().show()来显示，如果要屏蔽掉，则直接注释或删除这行代码就行
在这里插入图片描述

解锁过程代码

与Android 11类似的，可参照最下方的相关文章中Android 11的流程详解
frameworks/base/packages/SystemUI/src/com/android/keyguard/KeyguardSimPinViewController.java
verifyPasswordAndUnlock()函数是解锁时调用的, 下面代码我会在主要的代码点做注释

    @Overrideprotected void verifyPasswordAndUnlock() {String entry = mPasswordEntry.getText();// SIM PIN码必须大于等于4，小于等于8，如果长度不对这里会提示错误if (entry.length() > 8 || entry.length() < 4) {// otherwise, display a message to the user, and don't submit.mMessageAreaController.setMessage(com.android.systemui.R.string.kg_invalid_sim_pin_hint);mView.resetPasswordText(true /* animate */, true /* announce */);getKeyguardSecurityCallback().userActivity();return;}/* UNISOC: add for bug933599 @{ */if (mKeyguardUpdateMonitor.getSimState(mSubId) != TelephonyManager.SIM_STATE_PIN_REQUIRED) {Log.d(LOG_TAG, "keyguard sim state : " + mKeyguardUpdateMonitor.getSimState(mSubId) + ";" +"mSubId : " + mSubId);return;}/* @} */// 这里会有一个几秒闪一下的文本提示，提示正在解锁中getSimUnlockProgressDialog().show();if (mCheckSimPinThread == null) {// 调用CheckSimPin对输入的PIN进行解锁尝试mCheckSimPinThread = new CheckSimPin(mPasswordEntry.getText(), mSubId) {@Overridevoid onSimCheckResponse(final PinResult result) {// 这里是解锁的回调mView.post(() -> {mRemainingAttempts = result.getAttemptsRemaining();if (mSimUnlockProgressDialog != null) {mSimUnlockProgressDialog.hide();}mView.resetPasswordText(true /* animate */,/* announce */result.getResult() != PinResult.PIN_RESULT_TYPE_SUCCESS);if (result.getResult() == PinResult.PIN_RESULT_TYPE_SUCCESS) {// 解锁成功mShowDefaultMessage = false; // UNISOC: Modify for Bug 1737454mKeyguardUpdateMonitor.reportSimUnlocked(mSubId);mRemainingAttempts = -1;} else {mShowDefaultMessage = true; // UNISOC: Modify for Bug 1737454if (result.getResult() == PinResult.PIN_RESULT_TYPE_INCORRECT) {// 如果不成功就进入错误处理，更新提示mMessageAreaController.setMessage(getPinPasswordErrorMessage(result.getAttemptsRemaining(), false));//剩余次数变更if (result.getAttemptsRemaining() <= 2) {// this is getting critical - show dialoggetSimRemainingAttemptsDialog(result.getAttemptsRemaining()).show();} else {// show messagemMessageAreaController.setMessage(getPinPasswordErrorMessage(result.getAttemptsRemaining(), false));}} else {// "PIN operation failed!" - no idea what this was and no way to// find out. ://* SPRD : Modify for bug 921859 @{ */if (result.getResult() != PinResult.PIN_RESULT_TYPE_ABORTED) {if(DEBUG) Log.d(LOG_TAG, "verifyPasswordAndUnlock show kg_password_pin_failed");mMessageAreaController.setMessage(mView.getResources().getString(R.string.kg_password_pin_failed));}/* @} */}if (DEBUG) {Log.d(LOG_TAG, "verifyPasswordAndUnlock "+ " CheckSimPin.onSimCheckResponse: " + result+ " attemptsRemaining=" + result.getAttemptsRemaining());}}getKeyguardSecurityCallback().userActivity();mCheckSimPinThread = null;});}};mCheckSimPinThread.start();}}
