构建可在“图像查看”时检测颜色的应用程序。点击。不幸的是，在我摆脱了getResource（）。getContent（）＆＃39;的所有警告后，输出没有显示。或者我的＆＃39;如果＆＃39;是错的？也许有人可以帮助我:)。

答案 0 :(得分：1)
您要从rgb TextView为string.xml设置文字，因此您应该更改
colorRGB.setText(R.string.blue_colour);
到
colorRGB.setText(getResources().getString(R.string.blue_colour));
希望这个帮助
答案 1 :(得分：0)
肯定是的！您错误地使用了If，您正在初始化x
int x = 0;
并检查
if(x < 0)
总是返回false。
