[修正] Firemonkey Android Edit 可输入 Emoji (颜文字)

Posted 2020-08-20 龟山Aone

问题：在 android 平台下，显示 Emoji 文字，无法显示彩色（皆为黑色），例如 Edit 控件，即使将 Edit.ControlType = Platform 设为平台原生控件，还是没用（真机测试 Edit.ControlType 设定为 Style 与 Platform 是一样的，而 ios 平台则不同）。

修正方法：

请将源码 FMX.TextLayout.GPU.pas 复制到自己的工程目录里，再进行修改。

procedure TTextLayoutNG.DoDrawLayout(const ACanvas: TCanvas);
var
