我正在寻找一种方法将字符串的第一个字母转换为小写字母.我正在使用的代码从数组中提取随机字符串,在文本视图中显示字符串,然后使用它来显示图像.数组中的所有字符串的首字母大写,但存储在应用程序中的图像文件当然不能包含大写字母.
String source = "drawable/" //monb is randomly selected from an array,not hardcoded as it is here String monb = "Picture"; //I need code here that will take monb and convert it from "Picture" to "picture" String uri = source + monb; int imageResource = getResources().getIdentifier(uri,null,getPackageName()); ImageView imageView = (ImageView) findViewById(R.id.monpic); Drawable image = getResources().getDrawable(imageResource); imageView.setImageDrawable(image);
谢谢!
解决方法
if (monb.length() <= 1) { monb = monb.toLowerCase(); } else { monb = monb.substring(0,1).toLowerCase() + monb.substring(1); }
