Android14 Launcher3 定制主页丝滑使用Recents功能 (二)

一、Launcher3修改

1、修改最近任务页面清单配置

1)、清单xml修改

./packages/apps/Launcher3/quickstep/AndroidManifest.xml

修改前：

<activity android:name="com.android.quickstep.RecentsActivity"
     android:excludeFromRecents="true"
     android:launchMode="singleTask"
     android:clearTaskOnLaunch="true"
     android:stateNotNeeded="true"
     android:theme="@style/LauncherTheme"
     android:screenOrientation="unspecified"
     android:configChanges="keyboard|keyboardHidden|mcc|mnc|navigation|orientation|screenSize|screenLayout|smallestScreenSize"
     android:resizeableActivity="true"
     android:resumeWhilePausing="true"
     android:taskAffinity=""/>

修改后：

<activity android:name="com.android.quickstep.RecentsActivity"
     android:excludeFromRecents="true"
     android:launchMode="singleTask"
     android:clearTaskOnLaunch="true"
     android:stateNotNeeded="true"
     android:theme="@style/RecentsTheme"
     android:screenOrientation="unspecified"
     android:configChanges="keyboard|keyboardHidden|mcc|mnc|navigation|orientation|screenSize|screenLayout|smallestScreenSize"
     android:resizeableActivity="true"
     android:resumeWhilePausing="false"
     android:taskAffinity=""
     android:windowAnimationStyle="@style/NoAnimation" />

修改patch:

android:launchMode="singleTask"
              android:clearTaskOnLaunch="true"
              android:stateNotNeeded="true"
-             android:theme="@style/LauncherTheme"
+             android:theme="@style/RecentsTheme"
              android:screenOrientation="unspecified"
              android:configChanges="keyboard|keyboardHidden|mcc|mnc|navigation|orientation|screenSize|screenLayout|smallestScreenSize"
              android:resizeableActivity="true"
-             android:resumeWhilePausing="true"
-             android:taskAffinity=""/>
+             android:resumeWhilePausing="false"
+             android:taskAffinity=""
+             android:windowAnimationStyle="@style/NoAnimation" />

修改说明：

指定窗口动画为NoAnimation，不给窗口指定动画

指定theme为RecentsTheme，里面设置了背景图片

2)、style修改

./packages/apps/Launcher3/res/values/styles.xml
