2、屏幕触摸坐标修改为横屏

3、开机动画横屏

4、开机logo、关机充电动画横屏

5、RecoveryUI 横屏

上代码

1、app 强制横屏显示

修改 rotationForOrientationLw(), 默认返回 270

frameworks\base\services\core\java\com\android\server\policy\PhoneWindowManager.java

 @Override    public int rotationForOrientationLw(int orientation, int lastRotation, boolean defaultDisplay) {        ....        synchronized (mLock) {...default:                    // For USER, UNSPECIFIED, NOSENSOR, SENSOR and FULL_SENSOR,                    // just return the preferred orientation we already calculated.                    if (preferredRotation >= 0) {                        return preferredRotation;                    }                                        // return Surface.ROTATION_0;                    return Surface.ROTATION_270;//cczheng add for land scap            }        }  }

activity 默认强制属性为 SCREEN_ORIENTATION_LANDSCAPE

frameworks\base\services\core\java\com\android\server\wm\WindowManagerService.java

boolean updateOrientationFromAppTokensLocked(int displayId, boolean forceUpdate) {        long ident = Binder.clearCallingIdentity();        try {            final DisplayContent dc = mRoot.getDisplayContent(displayId);            // final int req = dc.getOrientation();            int req = android.content.pm.ActivityInfo.SCREEN_ORIENTATION_LANDSCAPE;//cczheng add for land scap            if (req != dc.getLastOrientation() || forceUpdate) {                if (DEBUG_ORIENTATION) {                    Slog.v(TAG, "updateOrientation: req= " + req + ", mLastOrientation= "                        + dc.getLastOrientation(), new Throwable("updateOrientation"));                }                dc.setLastOrientation(req);                //send a message to Policy indicating orientation change to take                //action like disabling/enabling sensors etc.,                // TODO(multi-display): Implement policy for secondary displays.                if (dc.isDefaultDisplay) {                    mPolicy.setCurrentOrientationLw(req);                }                return dc.updateRotationUnchecked(forceUpdate);            }            return false;        } finally {            Binder.restoreCallingIdentity(ident);        }    }

DisPlayContent 显示 mRotation 默认改为 3 (270)

frameworks\base\services\core\java\com\android\server\wm\DisplayContent.java

/**     * Current rotation of the display.     * Constants as per {@link android.view.Surface.Rotation}.     *     * @see #updateRotationUnchecked()     */    // private int mRotation = 0;    private int mRotation = 3;//cczheng add for land scap

修改默认值 config_reverseDefaultRotation 为 true,翻转显示角度

frameworks\base\core\res\res\values\config.xml

<!-- If true, the direction rotation is applied to get to an application's requested         orientation is reversed.  Normally, the model is that landscape is         clockwise from portrait; thus on a portrait device an app requesting         landscape will cause a clockwise rotation, and on a landscape device an         app requesting portrait will cause a counter-clockwise rotation.  Setting         true here reverses that logic. --><!-- cczheng add for land scap -->    <bool name="config_reverseDefaultRotation">true</bool> <!-- The number of degrees to rotate the display when the keyboard is open.         A value of -1 means no change in orientation by default. -->    <!-- cczheng add for land scap -->    <integer name="config_lidOpenRotation">270</integer>

2、屏幕触摸坐标修改为横屏

对调 frame 的宽和高,设置方向为 270

frameworks\native\services\surfaceflinger\DisplayDevice.cpp

void DisplayDevice::setProjection(int orientation,        const Rect& newViewport, const Rect& newFrame) {    Rect viewport(newViewport);    Rect frame(newFrame);    const int w = mDisplayWidth;    const int h = mDisplayHeight;    Transform R;    DisplayDevice::orientationToTransfrom(orientation, w, h, &R);    if (!frame.isValid()) {        // the destination frame can be invalid if it has never been set,        // in that case we assume the whole display frame.        //cczheng add for land scap        // frame = Rect(w, h);        if (w < h)            frame = Rect(h, w);        else            frame = Rect(w, h);    }....}// clang-format offDisplayDevice::DisplayDevice(        const sp<SurfaceFlinger>& flinger,        DisplayType type,        int32_t hwcId,        bool isSecure,        const wp<IBinder>& displayToken,        const sp<ANativeWindow>& nativeWindow,        const sp<DisplaySurface>& displaySurface,        std::unique_ptr<RE::Surface> renderSurface,        int displayWidth,        int displayHeight,        bool hasWideColorGamut,        const HdrCapabilities& hdrCapabilities,        const int32_t supportedPerFrameMetadata,        const std::unordered_map<ColorMode, std::vector<RenderIntent>>& hwcColorModes,        int initialPowerMode)      .....    mHdrCapabilities = HdrCapabilities(types, maxLuminance, maxAverageLuminance, minLuminance);    // initialize the display orientation transform.    // setProjection(DisplayState::eOrientationDefault, mViewport, mFrame);    //cczheng add for land scap    setProjection(DisplayState::eOrientation270, mViewport, mFrame);#ifdef MTK_SF_DEBUG_SUPPORT    mFps = FpsCounterLoader::getInstance().create();#endif}

frameworks\native\services\surfaceflinger\SurfaceFlinger.cpp

void SurfaceFlinger::onInitializeDisplays() {    // reset screen orientation and use primary layer stack    Vector<ComposerState> state;    Vector<DisplayState> displays;    DisplayState d;    d.what = DisplayState::eDisplayProjectionChanged |             DisplayState::eLayerStackChanged;    d.token = mBuiltinDisplays[DisplayDevice::DISPLAY_PRIMARY];    d.layerStack = 0;    //d.orientation = DisplayState::eOrientationDefault;    //cczheng add for land scap    d.orientation = DisplayState::eOrientation270;    d.frame.makeInvalid();    d.viewport.makeInvalid();    d.width = 0;    d.height = 0;    displays.add(d);  ....}

3、开机动画横屏

对调 createSurface() 的 w 和 h

frameworks\base\cmds\bootanimation\BootAnimation.cpp

status_t BootAnimation::readyToRun() {    mAssets.addDefaultAssets();    sp<IBinder> dtoken(SurfaceComposerClient::getBuiltInDisplay(            ISurfaceComposer::eDisplayIdMain));    DisplayInfo dinfo;    status_t status = SurfaceComposerClient::getDisplayInfo(dtoken, &dinfo);    if (status)        return -1;    // create the native surface    /*sp<SurfaceControl> control = session()->createSurface(String8("BootAnimation"),            dinfo.w, dinfo.h, PIXEL_FORMAT_RGB_565);*/    //cczheng add for land scap  [S]    sp<SurfaceControl> control;    if(dinfo.w < dinfo.h)        control = session()->createSurface(String8("BootAnimation"),            dinfo.h, dinfo.w, PIXEL_FORMAT_RGB_565);    else        control = session()->createSurface(String8("BootAnimation"),            dinfo.w, dinfo.h, PIXEL_FORMAT_RGB_565);    //cczheng add for land scap  [E]    SurfaceComposerClient::Transaction t;    t.setLayer(control, 0x40000000)        .apply();.....}

开机动画制作替换后面补充。。。

4、开机logo、关机充电动画横屏

开机logo定义屏幕分辨率以对应资源文件夹的位置为

vendor\mediatek\proprietary\bootable\bootloader\lk\project\xxxx.mk 没有则看下面的

device\mediateksample\xxxx\ProjectConfig.mk

mk 中的 BOOT_LOGO = wxga

对应的资源文件位置在 vendor/mediatek/proprietary/bootable/bootloader/lk/dev/logo/wxga

可以看到 wxga 中都是竖屏的图片,而 wxganl 中已经是横屏的图片

则我们将 BOOT_LOGO 修改为 wxganl 即可

接下来还需要继续修改显示的角度,依旧改成 270,不然会出现花屏的现象

开机第一张图片 uboot 对应显示

vendor\mediatek\proprietary\bootable\bootloader\lk\platform\mt6765\mt_logo.c

void init_fb_screen(){.....// in JB2.MP need to allign width and height to 32 ,but jb5.mp needn'tphical_screen.needAllign = 1;phical_screen.allignWidth = ALIGN_TO(CFG_DISPLAY_WIDTH, MTK_FB_ALIGNMENT);/* In GB, no need to adjust 180 showing logo ,for fb driver dealing the change *//* but in JB, need adjust it for screen 180 roration           */phical_screen.need180Adjust = 0;   // need sync with chip driverdprintf(INFO, "[lk logo: %s %d]MTK_LCM_PHYSICAL_ROTATION = %s\n",__FUNCTION__,__LINE__, MTK_LCM_PHYSICAL_ROTATION);if (0 == strncmp(MTK_LCM_PHYSICAL_ROTATION, "270", 3)) {phical_screen.rotation = 270;} else if (0 == strncmp(MTK_LCM_PHYSICAL_ROTATION, "90", 2)) {phical_screen.rotation = 90;} else if (0 == strncmp(MTK_LCM_PHYSICAL_ROTATION, "180", 3) && (phical_screen.need180Adjust == 1)) {phical_screen.rotation = 180;} else {phical_screen.rotation = 270;//cczheng add for land scap}....

开机第二张图片 kernel 对应显示

vendor\mediatek\proprietary\external\libshowlogo\charging_animation.cpp

int anim_fb_init(void){    .....    phical_screen.needAllign = 1;    phical_screen.need180Adjust = 1;    phical_screen.fb_size = fb_size;    if (MTK_LOG_ENABLE == 1) {        SLOGD("[libshowlogo: %s %d]MTK_LCM_PHYSICAL_ROTATION = %s\n",__FUNCTION__,__LINE__, MTK_LCM_PHYSICAL_ROTATION);    }    if(0 == strncmp(MTK_LCM_PHYSICAL_ROTATION, "270", 3))    {        phical_screen.rotation = 270;    } else if(0 == strncmp(MTK_LCM_PHYSICAL_ROTATION, "90", 2)){        phical_screen.rotation = 90;    } else if(0 == strncmp(MTK_LCM_PHYSICAL_ROTATION, "180", 3) && (phical_screen.need180Adjust == 1)){        phical_screen.rotation = 180;    } else {        phical_screen.rotation = 270;//cczheng add for land scap    }    if (MTK_LOG_ENABLE == 1) {        SLOGD("[libshowlogo]phical_screen: width= %d,height= %d,bits_per_pixel =%d,needAllign = %d,allignWidth=%d rotation =%d ,need180Adjust = %d\n",                phical_screen.width, phical_screen.height,                phical_screen.bits_per_pixel, phical_screen.needAllign,                phical_screen.allignWidth, phical_screen.rotation, phical_screen.need180Adjust);        SLOGD("[libshowlogo: %s %d]show old animtion= 1, running show_animationm_ver %d\n",__FUNCTION__,__LINE__, show_animationm_ver);        SLOGD("[libshowlogo: %s %d]draw_anim_mode = 1, running mode %d\n",__FUNCTION__,__LINE__, draw_anim_mode);    }    return 0;}

如果出现充电动画图片错位的现象,多数都是因为图形绘制点和屏幕尺寸不匹配导致的。可通过调整 cust_display.h 中位置参数

Android M 后:/vendor/mediatek/proprietary/external/libshowlogo/cust_display.h

Android M 前: /vendor/mediatek/proprietary/bootable/bootloader/lk/target/${PROJECT}/include/target/cust_display.h

(1 ,使用old version动画方案的调整如下设置,

define BAR_LEFT (215)

define BAR_TOP (156)

define BAR_RIGHT (265)

define BAR_BOTTOM (278)

可以用windows的画图软件打开第1点里提到的图片,根据电池边框的像素来调整。

这里坐标的参考原点是左上角,背景图片的左上角是(0,0),这四个值都是相对于左上角的坐标来确定的,因此RIGHT > LEFT,BOTTOM > TOP
小技巧:1)打开画图软件,选择 查看->缩放->自定义,将图片放到到800%
2)选择 查看->缩放->显示网格
这样就可以看到一个一个的像素
(2,使用new version动画方案调整如下设置:

#define CAPACITY_LEFT (278) #define CAPACITY_TOP (556)#define CAPACITY_RIGHT (441)#define CAPACITY_BOTTOM (817)

5、RecoveryUI 横屏

参考之前写的文章 MTK Recovery 模式横屏修改(适用于6.0 + 8.1+9.0)

6、系统导航栏位置调整,横屏后 navigationBarPosition 默认在左边

作为平板项目,需要将位置改为底部,直接修改 navigationBarPosition() 返回 NAV_BAR_BOTTOM

frameworks\base\services\core\java\com\android\server\policy\PhoneWindowManager.java

@NavigationBarPosition    private int navigationBarPosition(int displayWidth, int displayHeight, int displayRotation) {    //cchzneg annotaion for land scape        /*if (mNavigationBarCanMove && displayWidth > displayHeight) {            if (displayRotation == Surface.ROTATION_270) {                return NAV_BAR_LEFT;            } else {                return NAV_BAR_RIGHT;            }        }*/        return NAV_BAR_BOTTOM;    }

这样位置是变为底部了,但是三个按钮都重叠在一起了,需要修改 SystemUI 的布局显示

vendor\mediatek\proprietary\packages\apps\SystemUI\src\com\android\systemui\statusbar\phone\NavigationBarView.java

private void updateRotatedViews() {        //cczheng change rot0 rot90 for landscape        mRotatedViews[Surface.ROTATION_0] =                mRotatedViews[Surface.ROTATION_180] = findViewById(R.id.rot90);                // mRotatedViews[Surface.ROTATION_180] = findViewById(R.id.rot0);        mRotatedViews[Surface.ROTATION_270] =                mRotatedViews[Surface.ROTATION_90] = findViewById(R.id.rot0);                // mRotatedViews[Surface.ROTATION_90] = findViewById(R.id.rot90);                updateCurrentView();    }

顺带再调整下 NavigationBarView 的默认高度和左边 Back 键区域太大的问题

vendor\mediatek\proprietary\packages\apps\SystemUI\src\com\android\systemui\statusbar\phone\NavigationBarInflaterView.java

private View createView(String buttonSpec, ViewGroup parent, LayoutInflater inflater) {        View v = null;        String button = extractButton(buttonSpec);        if (LEFT.equals(button)) {             //cchzheng change NAVSPACE to MENU_IME for small left back click area            String s = Dependency.get(TunerService.class).getValue(NAV_BAR_LEFT, MENU_IME_ROTATE/*NAVSPACE*/);            button = extractButton(s);        } else if (RIGHT.equals(button)) {            String s = Dependency.get(TunerService.class).getValue(NAV_BAR_RIGHT, MENU_IME_ROTATE);            button = extractButton(s);        }...

frameworks\base\core\res\res\values\dimens.xml

 <!-- Height of the bottom navigation / system bar. -->    <!--cczheng change 48dp to 30dp-->    <dimen name="navigation_bar_height">30dp</dimen>

ok,这样就大功告成了,完美的横屏适配
