1.调整横屏模式下hotseat位置，由右侧调整为底部，并且解决allapps界面右侧空白问题
先使用dumpsys查看Launcher信息。
可以通过以下命令查找当前默认的Launcher。
adb shell cmd shortcut get-default-launcher
Launcher: ComponentInfo{com.android.launcher3/com.android.launcher3.uioverrides.QuickstepLauncher}
Success
进入对应的activity界面后，使用dumpsys 命令：adb shell dumpsys activity service com.android.launcher3
结果如下

可以看到isLandscape:true，表示当前是横屏。当前屏幕分辨率是720x720，当前其实是横屏竖用了。
如果只想改allapps界面右侧空白问题，可以参考这个：Android12 Launcher3横屏模式下，去掉allapps列表右侧空白
14上应该是对应这个函数：
// vendor/mediatek/proprietary/packages/apps/Launcher3/src/com/android/launcher3/DeviceProfile.java
private void updateHotseatSizes(int hotseatIconSizePx) {
// Ensure there is enough space for folder icons, which have a slightly larger radius.
hotseatCellHeightPx = (int) Math.ceil(hotseatIconSizePx * ICON_OVERLAP_FACTOR);
if (isVerticalBarLayout()) {
hotseatBarSizePx = hotseatIconSizePx + hotseatBarSidePaddingStartPx
+ hotseatBarSidePaddingEndPx;
} else if (isQsbInline) {
hotseatBarSizePx = Math.max(hotseatIconSizePx, hotseatQsbVisualHeight)
+ hotseatBarBottomSpacePx;
} else {
hotseatBarSizePx = hotseatIconSizePx
+ hotseatQsbSpace
+ hotseatQsbVisualHeight
+ hotseatBarBottomSpacePx;
}
}
由于我是调整横屏模式下hotseat位置，由右侧调整为底部，并且解决allapps界面右侧空白问题所以修改点如下，直接修改isVerticalBarLayout返回false即可：
vendor/mediatek/proprietary/packages/apps/Launcher3/src/com/android/launcher3/DeviceProfile.java
public boolean isVerticalBarLayout() {
- return isLandscape && transposeLayoutWithOrientation;
+ return false;
+ //return isLandscape && transposeLayoutWithOrientation;
}
如果是带gms包的版本，那就修改
这个位置的packages/apps/Launcher3/src/com/android/launcher3/DeviceProfile.java
