Android:按下按钮时更改listview中所有按钮的颜色

标签: java android listview

在列表视图中,每行有10个按钮。当按下任何按钮时,按钮的颜色应该改变(就像根据你按下的位置填充按钮一样)。 这是我到目前为止所做的: 我已将每个按钮的引用添加到名为buttons的ArrayList中。 另外,我有一个ArrayList,它有颜色字符串。 这是分配给每个按钮的单击侦听器。

这是listview的适配器类的完整代码。

public class TeacherRatingAdapter extends ArrayAdapter<Votes> {

    private ArrayList<String> colors = new ArrayList();

    private ArrayList<Button> buttons = new ArrayList<>();
    private LayoutInflater inflater;
    private ArrayList<Votes> mItems = new ArrayList<>();
    private ArrayList<Votes> mItemsTemp = new ArrayList<>();
    private int teacher;
    private boolean myTeacher;
    private ArrayList<Pair<Integer, Integer>> questionHint = new ArrayList<>();
    private static int givenMark;
    private HashMap<String, Integer> givenMarks = new HashMap<>();
    ViewHolder viewHolder;

    public TeacherRatingAdapter(Context context, TeacherRating teacherRating) {
        super(context, -1, teacherRating.getVotes());
        mItems = teacherRating.getVotes();
        if(mItems.size()==0){
            for(int i = 0; i<10; i++){
                mItems.add(new Votes());
            }
        }
        for(int i = 0; i<teacherRating.getVotes().size(); i++){
            givenMarks.put(String.valueOf(i+1), teacherRating.getVotes().get(i).getAll().get(i));
        }
        teacher = teacherRating.getTeacher();
        myTeacher = teacherRating.isMy_teacher();

        questionHint.add(new Pair<>(R.string.question1, R.string.questionHint1));
        questionHint.add(new Pair<>(R.string.question2, R.string.questionHint2));
        questionHint.add(new Pair<>(R.string.question3, R.string.questionHint3));
        questionHint.add(new Pair<>(R.string.question4, R.string.questionHint4));
        questionHint.add(new Pair<>(R.string.question5, R.string.questionHint5));
        questionHint.add(new Pair<>(R.string.question6, R.string.questionHint6));
        questionHint.add(new Pair<>(R.string.question7, R.string.questionHint7));
        questionHint.add(new Pair<>(R.string.question8, R.string.questionHint8));
        questionHint.add(new Pair<>(R.string.question9, R.string.questionHint9));
        questionHint.add(new Pair<>(R.string.question10, R.string.questionHint10));

    private void colorButton(long givenMark, ViewHolder viewHolder){

            Button button = buttons.get(j);
            button.setBackgroundColor(Color.parseColor(colors.get(j)));
        }
    }

    private static class ViewHolder {
        TextView mQuestionTextView;
        TextView mHintTextView;
        Button button1;
        Button button2;
        Button button3;
        Button button4;
        Button button5;
        Button button6;
        Button button7;
        Button button8;
        Button button9;
        Button button10;
    }
}

看起来像这样: enter image description here 因此,当我按下按钮3时,超过3的所有颜色必须变为白色。或者当我按下按钮9时,它前面的所有按钮都必须有颜色,而它前面的按钮必须是白色。但这不会发生,并且没有错误。 谢谢你的帮助。

不是评级栏吗?

OnClickListener是错误的,我的意思不是正确的倾听者,你的想法是错误的。什么是封闭的观点?
