rk3288 android9.0 设置界面添加状态栏按钮

Others 2021-11-18 02:23:34 views: null

前言

        我们公司是做工控机行业的，默认在android系统下是不允许有状态栏和导航栏的，之前在rk3288 android7.1.2系统下做过类似的处理，移植到rk3288 android9.0下面，两个版本在状态栏的代码差异还是比较大的，下面简单记录一下在android9.0上面添加状态栏按钮。

下面图片是完成后的状态

 当前状态栏的开启和关闭都使用广播实现

一、添加广播

1、添加系统广播首先要添加数据接口

frameworks/base/api/current.txt

     field public static final java.lang.String ACTION_ATTACH_DATA = "android.intent.action.ATTACH_DATA";
+    field public static final java.lang.String ACTION_BAR_SHOW = "android.intent.action.BAR_SHOW";
+    field public static final java.lang.String ACTION_BAR_HIDE = "android.intent.action.BAR_HIDE";
     field public static final java.lang.String ACTION_BATTERY_CHANGED = "android.intent.action.BATTERY_CHANGED";

2、定义广播内容

frameworks/base/core/java/android/content/Intent.java
    public static final String ACTION_BAR_SHOW = "android.intent.action.BAR_SHOW";
    public static final String ACTION_BAR_HIDE = "android.intent.action.BAR_HIDE";

3、动态注册广播

frameworks/base/packages/SystemUI/src/com/android/systemui/statusbar/phone/StatusBar.java
    filter.addAction(Intent.ACTION_BAR_SHOW);
    filter.addAction(Intent.ACTION_BAR_HIDE);

4、广播接收处理

frameworks/base/packages/SystemUI/src/com/android/systemui/statusbar/phone/StatusBar.java
    private final BroadcastReceiver mBroadcastReceiver = new BroadcastReceiver() {
        @Override
        public void onReceive(Context context, Intent intent) {
            if (DEBUG) Log.v(TAG, "onReceive: " + intent);
            String action = intent.getAction();
            if (Intent.ACTION_CLOSE_SYSTEM_DIALOGS.equals(action)) {
                KeyboardShortcuts.dismiss();
                if (mRemoteInputManager.getController() != null) {
                    mRemoteInputManager.getController().closeRemoteInputs();
                }
                if (mLockscreenUserManager.isCurrentProfile(getSendingUserId())) {
                    int flags = CommandQueue.FLAG_EXCLUDE_NONE;
                    String reason = intent.getStringExtra("reason");
                    if (reason != null && reason.equals(SYSTEM_DIALOG_REASON_RECENT_APPS)) {
                        flags |= CommandQueue.FLAG_EXCLUDE_RECENTS_PANEL;
                    }
                    animateCollapsePanels(flags);
                }
            }
            else if (Intent.ACTION_BAR_SHOW.equals(action)) {
                addBarInside();
                Settings.System.putInt(mContext.getContentResolver(), Settings.System.HIDE_NAVIGATION, 0);
                Log.d(TAG, "android.intent.action.ACTION_BAR_SHOW");
            }
            else if (Intent.ACTION_BAR_HIDE.equals(action)) {
                removeBar();
                Settings.System.putInt(mContext.getContentResolver(), Settings.System.HIDE_NAVIGATION, 1);
                Log.d(TAG, "android.intent.action.ACTION_BAR_HIDE");
            }
            else if (Intent.ACTION_SCREEN_OFF.equals(action)) {
                finishBarAnimations();
                resetUserExpandedStates();
            }
            else if (DevicePolicyManager.ACTION_SHOW_DEVICE_MONITORING_DIALOG.equals(action)) {
                mQSPanel.showDeviceMonitoringDialog();
            }
        }
    };

5、添加/移除状态栏和导航栏

  frameworks/base/packages/SystemUI/src/com/android/systemui/statusbar/phone/StatusBar.java 
    private boolean mBarIsAdd = true;
    private void changeBarStatus()
    {
        boolean show_systembar = Settings.System.getInt(mContext.getContentResolver(),Settings.System.HIDE_NAVIGATION,0)==1;
         if(show_systembar)
         {
             addBarInside();
         }
         else
         {
             removeBar();
         }
    }

    private void addBarInside(){
        boolean show_systembar = Settings.System.getInt(mContext.getContentResolver(),Settings.System.HIDE_NAVIGATION,0)==1;
        if (!mBarIsAdd && show_systembar){
            Log.d(TAG,"add Bar");
            createNavigationBar();
            mStatusBarWindow.setVisibility(View.VISIBLE);
            Settings.System.putInt(mContext.getContentResolver(),Settings.System.HIDE_NAVIGATION, 1);
            mBarIsAdd = true;
        }
    }

    private void removeBar(){
        if (mBarIsAdd){
            Log.d(TAG,"remove Bar");
        if (mNavigationBarView != null)
            mWindowManager.removeView(mNavigationBarView);
        if (mStatusBarWindow != null)
            mStatusBarWindow.setVisibility(View.GONE);
            mBarIsAdd = false;
        }
        Settings.System.putInt(mContext.getContentResolver(),Settings.System.HIDE_NAVIGATION, 0);
    }

6、系统初始状态栏设置

    @@ -909,7 +909,9 @@ public class StatusBar extends SystemUI implements DemoMode,

             if (showNav) {
-                createNavigationBar();
+                if (1 == Settings.System.getInt(mContext.getContentResolver(), Settings.System.HIDE_NAVIGATION, 1)) {
+                    createNavigationBar();
