4.android6.0 TV 添加自定义导航栏
Android TV 通常是用遥控器操作的，系统导航栏都是关闭的，但带触摸的TV就很有必要加上导航栏了。
1. 修改base/core/res/res/values/config.xml
base/core/res/res/values/config.xml- <bool name="config_showNavigationBar">false</bool>+ <bool name="config_showNavigationBar">true</bool>
但是在TV 上屏通常是横屏的，手机上是竖屏的，仅仅打开上面这个设置，在TV 右边屏幕就会有一个黑条的导航栏，但没有图标，这时候就要把导航栏想办法改到屏幕下面，
2. base/services/core/java/com/android/server/policy/PhoneWindowManager.java
mNavigationBarOnBottom这个值决定导航条的位置，从名字就看的出来，true 的时候是底部，false在垂直右边，在TV 屏的1920x1080分辨率上这个值 为false,所以直接改为true
主要代码在setInitialDisplaySize， 和beginLayoutLw这两个函数里，包括导航栏的位置，其实X,Y 坐标，长宽等到
public voidsetInitialDisplaySize(Display display, int width, int height, int density) {
......................................
mNavigationBarCanMove = width != height && shortSizeDp < 600;这个值在setInitialDisplaySize函数里
........................................
public voidbeginLayoutLw(boolean isDefaultDisplay, int displayWidth, int displayHeight,
int displayRotation) {
mNavigationBarOnBottom =true;//(!mNavigationBarCanMove || displayWidth < displayHeight);
if (mNavigationBarOnBottom) {
// It's a system nav bar or a portrait screen; nav bar goes on bottom.
inttop= displayHeight - overscanBottom//计算底部显示的 Y 坐标
- 100;//mNavigationBarHeightForRotation[displayRotation];这个值是导航栏的宽度，在setInitialDisplaySize计算出来是0，
实际Y 坐标top就是1080了，这 样看不到了导航栏了，这里直接改成100
mTmpNavigationFrame.set(0, top, displayWidth, displayHeight - overscanBottom);//设置导航栏位置大小
................................
} else {
// Landscape screen; nav bar goes to the right.
intleft= displayWidth - overscanRight//计算在右边显示 X 坐标
- mNavigationBarWidthForRotation[displayRotation];
mTmpNavigationFrame.set(left, 0, displayWidth - overscanRight, displayHeight);
................................
这样导航栏的三个图标就出来了
3. 修改base/packages/SystemUI/res/layout/navigation_bar.xml 实现自定义布局
在base/packages/SystemUI/src/com/android/systemui/statusbar/phone/NavigationBarView.java 文件的函数
public void onFinishInflate() {
mRotatedViews[Surface.ROTATION_0] =mRotatedViews[Surface.ROTATION_180] = findViewById(R.id.rot0);
mRotatedViews[Surface.ROTATION_90] = findViewById(R.id.rot90);
mRotatedViews[Surface.ROTATION_270] = mRotatedViews[Surface.ROTATION_90];
mCurrentView = mRotatedViews[Surface.ROTATION_0];TV 实际用的这个，所以布局里就只修改
}
注意：原来的返回，主页，任务的三个图标，代码里面还会引用图片的名字。如果要替换，最好把要换的图片名字改成原来的一样，直接覆盖替换，否则代码里还要同步修改。
4. 修改按钮事件
layout 文件里每个KeyButtonView下有一个systemui:keyCode="4"，对应按键映射码，最终会在KeyButtonView 里取出来赋值给mCode = a.getInteger(R.styleable.KeyButtonView_keyCode, 0); 在sendEvent 里虚拟一个按键事件把这个按键发送出去。对于其他新增加的按钮事件，可以找一个没用到的按键当作该按钮的按键，比如定义为KEYCODE_F1， 在navigation_bar.xml 里修改systemui:keyCode="131"，再在PhoneWindow.java 的onKeyDown里添加下面代码，就可以在任何界面都能打开该activity了
case KeyEvent.KEYCODE_F1: {Intent itent = new Intent();itent.setClassName("com.supera.board", "com.supera.board.MainActivity");mContext.startActivity(itent);return true;}
最终的自定义导航栏就如下面的效果
5. 修改导航栏的背景色
在navigation_bar.xml 里有 android:background="@drawable/system_bar_background" 这一行，实际光修改这里是不起作用的，参考/kongbaidepao/article/details/82118406这篇文章，屏蔽掉一行
再修改 android:background="@drawable/system_bar_background" 就可以自定义背景颜色了
6. 修改导航栏的动态隐藏显示
参考/way_ping_li/article/details/45727335修改后，隐藏没有问题，但手势滑不出来导航栏，经过查找发现SystemGesturesPointerEventListener.java 文件里的screenWidth ，screenHeight ，mSwipeStartThreshold 这是三个值都是0，导致在下面函数返回SWIPE_NONE
添加如下一段代码功能就正常手势滑开了
public SystemGesturesPointerEventListener(Context context, Callbacks callbacks) {..................WindowManager wm = (WindowManager)context.getSystemService(Context.WINDOW_SERVICE); screenWidth = wm.getDefaultDisplay().getWidth(); screenHeight = wm.getDefaultDisplay().getHeight(); mSwipeStartThreshold = 20;//checkNull("context", context).getResources()................
6.隐藏状态栏
frameworks/base/core/res/res/values/dimens.xml
将高度 24 改成 0 android 11上此方法只会隐藏顶部那部分UI，想要隐藏下拉的状态栏，还需要改动java代码如下：
framework/base/packages/SystemUI/src/android/systemui/statusbar/phone/StatusBar.java
makeStatusBarView函数设置mStatusBarView.setVisibility(View.GONE);
// ================================================================================// Constructing the view// ================================================================================protected void makeStatusBarView(@Nullable RegisterStatusBarResult result) {final Context context = mContext;updateDisplaySize(); // populates mDisplayMetricsupdateResources();updateTheme();inflateStatusBarWindow();mNotificationShadeWindowViewController.setService(this, mNotificationShadeWindowController);mNotificationShadeWindowView.setOnTouchListener(getStatusBarWindowTouchListener());// TODO: Deal with the ugliness that comes from having some of the statusbar broken out// into fragments, but the rest here, it leaves some awkward lifecycle and whatnot.mStackScroller = mNotificationShadeWindowView.findViewById(R.id.notification_stack_scroller);NotificationListContainer notifListContainer = (NotificationListContainer) mStackScroller;mNotificationLogger.setUpWithContainer(notifListContainer);// TODO: make this injectable.
