Android13定制状态栏导航栏

一、状态栏的隐藏与体现
SystemUI模块修改文件如下：
frameworks/base/packages/SystemUI/src/com/android/systemui/statusbar/phone/CentralSurfacesImpl.java

frameworks/base/packages/SystemUI/src/com/android/systemui/statusbar/window/StatusBarWindowController.java

二、导航栏的隐藏与体现
packages/apps/Launcher3/quickstep/src/com/android/launcher3/taskbar/TaskbarManager.java

packages/apps/Launcher3/quickstep/src/com/android/quickstep/TouchInteractionService.java

三、Settings模块修改添加开关：
packages/apps/Settings/res/xml/display_settings.xml

packages/apps/Settings/src/com/android/settings/display/status_navi_bar/NaviBarPreferenceController.java

1. package com.android.settings.display.status_navi_bar;
3. import android.content.Context;
4. import android.content.Intent;
5. import android.os.SystemProperties;
6. import android.preference.Preference;
7. import android.util.Log;
9. import com.android.settings.core.BasePreferenceController;
10. import com.android.settings.core.PreferenceControllerMixin;
11. import com.android.settings.core.TogglePreferenceController;
12. import com.android.settingslib.core.lifecycle.LifecycleObserver;
13. import com.android.settingslib.core.lifecycle.events.OnPause;
14. import com.android.settingslib.core.lifecycle.events.OnResume;
16. public class NaviBarPreferenceController extends TogglePreferenceController implements PreferenceControllerMixin, Preference.OnPreferenceChangeListener, LifecycleObserver, OnResume, OnPause {
18.     private static final String TAG = "NaviBarPreferenceController";
20.     private static final String SYS_PROPERTY_NAVIGATION_BAR = "persist.sys.navigationbar.enable";
21.     private static final String ACTION_HIDE_NAVIGATION_BAR = "com.systemui.navigationbar.hide";
22.     private static final String ACTION_SHOW_NAVIGATION_BAR = "com.systemui.navigationbar.show";
23.     private Context mContext;
24.     public NaviBarPreferenceController(Context context, String preferenceKey) {
25.         super(context, preferenceKey);
26.         mContext = context;
27.     }
29.     @Override
30.     public int getAvailabilityStatus() {
31.         return BasePreferenceController.AVAILABLE;
32.     }
34.     @Override
35.     public boolean isChecked() {
36.         return !SystemProperties.getBoolean(SYS_PROPERTY_NAVIGATION_BAR, false);
37.     }
39.     @Override
40.     public boolean setChecked(boolean isChecked) {
41.         Log.d(TAG, "setChecked: " + isChecked);
42.         Intent intent = isChecked ? new Intent(ACTION_HIDE_NAVIGATION_BAR) : new Intent(ACTION_SHOW_NAVIGATION_BAR);
43.         mContext.sendBroadcast(intent);
44.         return true;
45.     }
47.     @Override
48.     public int getSliceHighlightMenuRes() {
49.         return NO_RES;
50.     }
52.     @Override
53.     public boolean onPreferenceChange(Preference preference, Object newValue) {
54.         Log.d(TAG, "onPreferenceChange: "+newValue);
55.         return true;
56.     }
58.     @Override
59.     public void onPause() {
60.         Log.d(TAG, "onPause: ");
61.     }
63.     @Override
64.     public void onResume() {
65.         Log.d(TAG, "onResume: ");
66.     }
67. }
