如何更改按钮中名称的颜色，以使每个人对于BaseAdapter中特定字母的颜色都不相同，在视图中我在其中创建按钮？
此刻，在getView（）方法中，我检查答案是否为空，如果是，则设置默认的蓝色并且一切都很好，但是我想区分特定索引的列表何时已满列表中的3,6,7设置了与当前示例不同的文本颜色，而不是绿色。
public class GridViewAnswerAdapter extends BaseAdapter {
private List<String> answer;
private Context context;
private MainActivity mainActivity;
public GridViewAnswerAdapter(List<String> answer, Context context, MainActivity mainActivity) {
this.answer = answer;
this.context = context;
this.mainActivity = mainActivity;
}
@Override
public int getCount() {
return answer.size();
}
@Override
public Object getItem(int position) {
return answer.get(position);
}
@Override
public long getItemId(int position) {
return position;
}
@Override
public View getView(final int position, View convertView, ViewGroup parent) {
Button buttonAnswerAdapter = null;
if (convertView == null) {
if (answer.get(position).equals(" ")) {
buttonAnswerAdapter = new Button(context);
buttonAnswerAdapter.setLayoutParams(new GridView.LayoutParams(100, 100));
buttonAnswerAdapter.setPadding(8, 8, 8, 8);
buttonAnswerAdapter.setBackgroundColor(Color.BLUE);
} else if (mainActivity.listAnswer.get(position).equals(answer.get(position))) {
//Create new button
buttonAnswerAdapter = new Button(context);
buttonAnswerAdapter.setLayoutParams(new GridView.LayoutParams(100, 100));
buttonAnswerAdapter.setPadding(8, 8, 8, 8);
buttonAnswerAdapter.setBackgroundColor(Color.BLUE);
buttonAnswerAdapter.setTextColor(Color.GREEN);
buttonAnswerAdapter.setText(String.valueOf(answer.get(position)));
} else {
buttonAnswerAdapter = (Button) convertView;
}
}
return buttonAnswerAdapter;
}
}
我尝试通过以下方式进行操作：检查新列表是否包含答案中的字符，然后将文本的颜色更改为红色，但是不幸的是，我将所有字母更改为红色，并再次搜索列表时再次，所有文本颜色都会更改。而且我只想更改一种特定的一键式文本，而不是针对所有人。
我的尝试失败：
