[修正] Firemonkey Android 显示 Emoji (颜文字)

2016-11-19 11:30:20来源:cnblogs.com作者:龟山Aone人点击

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
