[英]Change textView color in RecyclerView.Adapter
I want to change the color of a textView in the onBindViewHolder in the Adapter depending on a variable of data.我想根据数据变量更改适配器中 onBindViewHolder 中 textView 的颜色。 I've tried this
我试过这个
if (survey.getAnonymous() == 0) {
holder.surveyIcon.setImageResource(R.drawable.ic_x);
holder.surveyAnonymous.setTextColor(R.color.red);
} else {
holder.surveyIcon.setImageResource(R.drawable.ic_check);
holder.surveyAnonymous.setTextColor(R.color.green);
}
R.color.red
is underlined in red and says R.color.red
红色下划线并表示
Should use getResources().getColor(R.color.red)
应该使用 getResources().getColor(R.color.red)
I tried that and it also gives me an error.我试过了,它也给了我一个错误。 I have tried these:
我试过这些:
holder.surveyAnonymous.setTextColor(R.color.red);
holder.surveyAnonymous.setTextColor(getResources().getColor(R.color.red));
holder.surveyAnonymous.setTextColor(getColor(R.color.red));
holder.surveyAnonymous.setTextColor(Color.parseColor(R.color.red);
None of these have worked and are always underlined in red, what is the correct way to do this?这些都没有用,并且总是用红色下划线,正确的方法是什么?
int getColor (Context context, int id)
int getColor (上下文上下文,int id)
holder.surveyAnonymous.setTextColor(ContextCompat.getColor(contextObject,(R.color.red)));
FYI供参考
Color.parseColor
- Parse the color string, and return the corresponding color-int. Color.parseColor
- 解析颜色字符串,返回对应的color-int。
holder.surveyAnonymous.setTextColor(Color.parseColor("#54D66A");
