Android TextView : “Do not concatenate text displayed with setText” _TextView

敢说敢作敢为，无怨无恨无悔。这篇文章主要讲述Android TextView : “Do not concatenate text displayed with setText”相关的知识，希望能为你提供帮助。

在Activity中对TextView进行动态更新显示数据时，如果使用:

RGB_textview.setText(settingData.Image_R + "," + settingData.Image_G + "," + settingData.Image_B);

则Android Studio 会提示：“Do not concatenate text displayed with setText，use resource string with placeholders”，
应改为：

RGB_textview.setText(getString(R.string.RGB_value_string, settingData.Image_R, settingData.Image_G, settingData.Image_B));
< string name="RGB_value_string"> %1$d,%2$d,%3$d< /string>

不修改也能正常运行，但修改一下会更加规范。

常用格式:
%n$s---> n表示目前是第几个参数（比如%1$s中的1代表第一个参数）,s代表字符串
%n$d---> n表示目前是第几个参数（比如%1$d中的1代表第一个参数）,d代表整数
%n$f---> n表示目前是第几个参数（比如%1$f中的1代表第一个参数）,f代表浮点数

When calling TextView#setText:

Never call Number#toString() to format numbers; it will not handle fraction separators and locale-specific digits properly. Consider using String#format with proper format specifications (%d or %f) instead.
Do not pass a string literal (e.g. "Hello") to display text. Hardcoded text can not be properly translated to other languages. Consider using Android resource strings instead.
Do not build messages by concatenating text chunks. Such messages can not be properly translated.
