Question

我对Android非常陌生，我想在Listview中更改TextView的文本颜色。尝试这个时，颜色不会改变。谁可以帮我解决这个（简单？）问题？

我在我的＆＃34; BaseAdapter＆＃34;中使用以下代码控制ListView：

    public View getView(int i, View view, ViewGroup viewGroup) {


    if (view == null) {
        view = mInflater.inflate(R.layout.cijfer_listitem, null);

        holder = new ViewHolder();
        holder.mCijferTxt = (TextView) view.findViewById(R.id.cijferTxt);
        holder.mVakTxt = (TextView) view.findViewById(R.id.vakTxt);
        holder.mVakUitgebreidTxt = (TextView) view.findViewById(R.id.vakUitgebreidTxt);
        holder.mIdTxt = (TextView) view.findViewById(R.id.idTxt);

        view.setTag(holder);
    } else {
        holder = (ViewHolder) view.getTag();

    }

    Cijfer cijfer = mCijfers.get(i);

    holder.mCijferTxt.setText(cijfer.getCijfer());
    holder.mVakTxt.setText(cijfer.getCursus());
    holder.mVakUitgebreidTxt.setText(cijfer.getCursusUitgebreid());
    holder.mIdTxt.setText("" + cijfer.getCijferID());

    if (cijfer.isDef() == true ){

        holder.mCijferTxt.setTextColor(R.color.colorTxtDef);
    }
    else{
        holder.mCijferTxt.setTextColor((R.color.colorTxtConcept));
    }

    return view;
}

public class ViewHolder {
    public TextView mCijferTxt;
    public TextView mVakTxt;
    public TextView mVakUitgebreidTxt;
    public TextView mIdTxt;
}

我想改变TextView＆＃34; cijferTxt＆＃34;的颜色。

希望这足以让你帮助我：）

Answer 1

试试这个

 holder.setTextColor(view.getResources().getColor(R.color.colorTxtDef));

Answer 2

您正在尝试将文本颜色设置为颜色资源ID（它只是指向颜色的ID）。您需要从此颜色资源ID中提取颜色。例如：

int color = context.getResources().getColor(R.color.colorTxtDef);
holder.mCijferTxt.setTextColor(color);
