Question

我在对话框中有一个ListView＆amp;我想在ListView中将项目TextColor设置为Brown，因此我将此适配器用于我的ListView：

public class RankingListAdapter extends BaseAdapter {

private Context context;
private ArrayList<RankingItem> RankingItems;
int Po;

public RankingListAdapter(Context context, ArrayList<RankingItem> navDrawerItems, int p) {
    this.context = context;
    this.RankingItems = navDrawerItems;
    this.Po = p;
}

@Override
public int getCount() {
    return RankingItems.size();
}

@Override
public Object getItem(int position) {
    return RankingItems.get(position);
}

@Override
public long getItemId(int position) {
    return position;
}

@Override
public View getView(int position, View convertView, ViewGroup parent) {

    if (convertView == null) {
        LayoutInflater mInflater = (LayoutInflater)
                context.getSystemService(Activity.LAYOUT_INFLATER_SERVICE);
        convertView = mInflater.inflate(R.layout.ranking_list_item, null);
    }

    TextView TVRank = (TextView) convertView.findViewById(R.id.TVRank);
    TextView TVUser = (TextView) convertView.findViewById(R.id.TVUser);
    TextView TVLVL = (TextView) convertView.findViewById(R.id.TVLVL);
    TextView TVScore = (TextView) convertView.findViewById(R.id.TVScore);
    Typeface TEng = Typeface.createFromAsset(context.getAssets(), "fonts/English.ttf");
    Typeface TNum = Typeface.createFromAsset(context.getAssets(), "fonts/Nums.ttf");

    TVRank.setText(RankingItems.get(position).getRank());
    TVRank.setTypeface(TNum);
    TVUser.setText(RankingItems.get(position).getUsername());
    TVUser.setTypeface(TEng);
    TVLVL.setText(RankingItems.get(position).getLVL());
    TVLVL.setTypeface(TNum);
    TVScore.setText(RankingItems.get(position).getScore());
    TVScore.setTypeface(TNum);

    if (position == Po) {
        TVRank.setTextColor(Color.parseColor("#b38620"));
        TVUser.setTextColor(Color.parseColor("#b38620"));
        TVLVL.setTextColor(Color.parseColor("#b38620"));
        TVScore.setTextColor(Color.parseColor("#b38620"));
    }

    return convertView;
}
}

但是当我运行我的应用程序时，我看到了这个： enter image description here

问题是什么？

Answer 1

也为颜色写

 if (position == Po) {
    TVRank.setTextColor(Color.parseColor("#b38620"));
    TVUser.setTextColor(Color.parseColor("#b38620"));
    TVLVL.setTextColor(Color.parseColor("#b38620"));
    TVScore.setTextColor(Color.parseColor("#b38620"));
}
else
{
    //set default color of your texts.
    TVRank.setTextColor(Color.BLACK);
    TVUser.setTextColor(Color.BLACK);
    TVLVL.setTextColor(Color.BLACK);
    TVScore.setTextColor(Color.BLACK);        
}

Answer 2

设置else条件，并在else条件下写下要设置的颜色。试试这个

if (position == Po) {
    TVRank.setTextColor(Color.parseColor("#b38620"));
    TVUser.setTextColor(Color.parseColor("#b38620"));
    TVLVL.setTextColor(Color.parseColor("#b38620"));
    TVScore.setTextColor(Color.parseColor("#b38620"));
}else{
      //set your required color to the required textView here
}
