Android 13 移除下拉栏中的设置入口

本文主要是介绍Android 13 移除下拉栏中的设置入口，希望对大家解决编程问题提供一定的参考价值，需要的开发者们随着小编来一起学习吧！

介绍

因为当前项目的设置已被加密，客户不希望通过下拉窗口的设置图标进入设置，决定去掉该图标。

分析

这里首先想到在SystemUI寻找这个图标的资源文件，找到资源文件后寻找对应控件调用的地方，根据id寻找控件代码即可。

修改

首先找到了对应的资源文件

路径：vendor/mediatek/proprietary/packages/apps/SystemUI/res/drawable/ic_settings.xml

通过搜索我们发现是在如下路径调用，这里我按钮是在容器中的，我们直接搜索容器ID的绑定代码。

路径：vendor/mediatek/proprietary/packages/apps/SystemUI/res-keyguard/layout/footer_actions.xml

        <com.android.systemui.statusbar.AlphaOptimizedFrameLayoutandroid:id="@+id/settings_button_container"android:layout_width="@dimen/qs_footer_action_button_size"android:layout_height="@dimen/qs_footer_action_button_size"android:background="@drawable/qs_footer_action_circle"android:clipChildren="false"android:clipToPadding="false"><com.android.systemui.statusbar.phone.SettingsButtonandroid:id="@+id/settings_button"android:layout_width="@dimen/qs_footer_icon_size"android:layout_height="@dimen/qs_footer_icon_size"android:layout_gravity="center"android:background="@android:color/transparent"android:focusable="false"android:clickable="false"android:importantForAccessibility="yes"android:contentDescription="@string/accessibility_quick_settings_settings"android:scaleType="centerInside"android:src="@drawable/ic_settings"android:tint="?android:attr/textColorPrimary" /></com.android.systemui.statusbar.AlphaOptimizedFrameLayout>

控件是在onFinishInflate中完成绑定的，接着往下看,在updateVisibilities中更新了控件的显示状态，那只需在最后设置显示状态为GONE即可，代码如下

路径：vendor/mediatek/proprietary/packages/apps/SystemUI/src/com/android/systemui/qs/FooterActionsView.kt

    override fun onFinishInflate() {super.onFinishInflate()settingsContainer = findViewById(R.id.settings_button_container)multiUserSwitch = findViewById(R.id.multi_user_switch)multiUserAvatar = multiUserSwitch.findViewById(R.id.multi_user_avatar)// RenderThread is doing more harm than good when touching the header (to expand quick// settings), so disable it for this viewif (settingsContainer.background is RippleDrawable) {(settingsContainer.background as RippleDrawable).setForceSoftware(true)}importantForAccessibility = View.IMPORTANT_FOR_ACCESSIBILITY_YES}private fun updateVisibilities(multiUserEnabled: Boolean) {settingsContainer.visibility = if (qsDisabled) GONE else VISIBLEmultiUserSwitch.visibility = if (multiUserEnabled) VISIBLE else GONEval isDemo = UserManager.isDeviceInDemoMode(context)//*/soda water.20240109 Remove the drop-down Settings entrysettingsContainer.visibility = GONE/*settingsContainer.visibility = if (isDemo) INVISIBLE else VISIBLE*/}
