Question

我正在构建Android计算器应用程序的键盘。我正在使用unicode，但应用程序没有显示“擦除到左边”按钮

static String[][] screen2L ={{"sin","asin","sinh","asinh","sind","asind","\u232B","AC"},
                             {"cos","acos","cosh","acosh","cosd","acosd","log2","gamma"},
                             {"tan","atan","tanh","atanh","tand","atand","log10","ln"}};

感谢

Answer 1

所有字体都不支持Unicode字符。点击此处查看\u232B

支持的字体

不要使用角色，而是制作角色的图像并将其设置为按钮背景。可以提供帮助的帖子已在此处得到解答：How to make button with custom background image...

另外，至于在java中使用字符串在GUI中打印，最好使用xml。按钮各个值将存储到应用程序，而不必在每次运行应用程序时分配它们。我会写出如何完成此操作的说明，但Android开发人员指南that can be found here提供了比我更好的指令。

Unicode字符（“\ u232B”）不显示在按钮上
