预制客供壁纸

之前这个功能在 6.0 上修改过，已经是三年前了，之前壁纸选择还集成在 Launcher3 中，当时参考这篇

https://blog.csdn.net/jspping/article/details/50569097 进行的修改

Q 版本中已经独立出来了，在 WallpaperPicker 中进行修改

制作缩略图，将客户提供的壁纸丢给美工制作对应的缩略图，然后将所有资源图片放置到

vendor\mediatek\proprietary\packages\apps\WallpaperPicker\res\drawable-xhdpi

我这里预制两张,注意文件命名

vendor/mediatek/proprietary/packages/apps/WallpaperPicker/res/drawable-xhdpi/wallpaper_01.png                 
vendor/mediatek/proprietary/packages/apps/WallpaperPicker/res/drawable-xhdpi/wallpaper_01_small.png       
vendor/mediatek/proprietary/packages/apps/WallpaperPicker/res/drawable-xhdpi/wallpaper_02.png                 
vendor/mediatek/proprietary/packages/apps/WallpaperPicker/res/drawable-xhdpi/wallpaper_02_small.png

将刚刚所添加的 png 壁纸名称配置 wallpapers.xml

vendor\mediatek\proprietary\packages\apps\WallpaperPicker\res\values-nodpi\wallpapers.xml

<resources><string-array name="wallpapers" translatable="false"><item>wallpaper_01</item><item>wallpaper_02</item></string-array>
</resources>

调整获取默认壁纸尺寸大小值

vendor\mediatek\proprietary\packages\apps\WallpaperPicker\src\com\android\wallpaperpicker\WallpaperUtils.java

public static Point getDefaultWallpaperSize(Resources res, WindowManager windowManager) {if (sDefaultWallpaperSize == null) {Point realSize = new Point();windowManager.getDefaultDisplay().getRealSize(realSize);int maxDim = Math.max(realSize.x, realSize.y);int minDim = Math.min(realSize.x, realSize.y);// We need to ensure that there is enough extra space in the wallpaper// for the intended parallax effectsfinal int defaultWidth, defaultHeight;if (res.getConfiguration().smallestScreenWidthDp >= 720) {defaultWidth = (int) (maxDim * wallpaperTravelToScreenWidthRatio(maxDim, minDim));defaultHeight = maxDim;} else {//defaultWidth = Math.max((int) (minDim * WALLPAPER_SCREENS_SPAN), maxDim);//defaultHeight = maxDim;//add begin set full screen  startdefaultWidth = realSize.x;defaultHeight = realSize.y;         //add begin set full screen  end}//add begin set full screen  start//sDefaultWallpaperSize = new Point(defaultWidth, defaultHeight);sDefaultWallpaperSize = realSize;//add begin set full screen  end}return sDefaultWallpaperSize;}
