Question

下面的代码不起作用，有什么更改文字颜色的正确方法吗？

public class Adapter extends RecyclerView.Adapter<Adapter.ViewHolder> {

    private List<TodayGmodel> model;
    private Context context;

    public Adapter(Context context, List<TodayGmodel> model) {
        this.model = model;
        this.context = context;
    }

    @Override
    public Adapter.ViewHolder onCreateViewHolder(ViewGroup viewGroup, int i) {
        View view = LayoutInflater.from(viewGroup.getContext()).inflate(R.layout.timer_adapter_layout, viewGroup, false);
        return new ViewHolder(view);
    }

    @Override
    public void onBindViewHolder(final Adapter.ViewHolder viewHolder, int position) {
        TodayGmodel todayGmodel = model.get(position);
        viewHolder.refreshTime(todayGmodel.getCalculateEnd());

        Log.e("timerLogList", "" + model.get(position).getCalculateEnd());
    }

    @Override
    public void onViewAttachedToWindow(@NonNull ViewHolder holder) {
        int pos = holder.getAdapterPosition();
        TodayGmodel todayGmodel = model.get(pos);

        holder.refreshTime(todayGmodel.getCalculateEnd());
    }

    @Override
    public void onViewDetachedFromWindow(@NonNull ViewHolder holder) {
        if (holder.getDownTimer() != null)
            holder.getDownTimer().cancel();
    }

    @Override
    public int getItemCount() {
        return model.size();
    }

    public class ViewHolder extends RecyclerView.ViewHolder {

        public TextView tv_timer;
        private CountDownTimer downTimer;
        private long remainTime = 0;

        public ViewHolder(View view) {
            super(view);

        }

        public void refreshTime(long timer) {

                        int tempMint = (seconds - (hours * 60 * 60));
                        int minutes = tempMint / 60;
                        seconds = tempMint - (minutes * 60);
                        tv_timer.setText(String.format("%02d", hours)
                                + ":" + String.format("%02d", minutes)
                                + ":" + String.format("%02d", seconds));
                        if (remainTime > 50) {
                            tv_timer.setBackgroundColor(ContextCompat.getColor(context, R.color.color1));
                        } else if (remainTime < 50 && remainTime > 20){
                            tv_timer.setBackgroundColor(ContextCompat.getColor(context, R.color.color2));
                        } else {
                            tv_timer.setBackgroundColor(ContextCompat.getColor(context, R.color.color4));
                        }
                    }

                    @Override

                    }
                }.start();
            } else {

                if (downTimer != null)
                    downTimer.cancel();

    }
}

<xsl:text color="green">Sold</xsl:text>

xslt中没有像color这样的属性。您必须在要为文本着色的位置提供格式和输入。

如何更改文本元素的颜色？
