Android：按下按钮时更改列表视图中所有按钮的颜色
[英]Android: Change color of all buttons in listview when a button pressed
问题描述
在列表视图的每一行中，我有10个按钮。 当按下这些按钮中的任何一个时，按钮的颜色应该改变（就像按您按下的位置填充条一样）。 到目前为止，这是我所做的：我已将每个按钮的引用添加到称为按钮的ArrayList中。 另外，我有一个带有颜色字符串的ArrayList。 这是分配给每个按钮的单击侦听器。
这是列表视图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));

} else {

}
viewHolder.mQuestionTextView.setText(questionHint.get(position).getValue0());
viewHolder.mHintTextView.setText(questionHint.get(position).getValue1());
Votes item = getItem(position);
int count = 0;
double score = 0;
for(int i = 0; i<item.getAll().size(); i++){
score += (i+1) * item.getAll().get(i);
count +=item.getAll().get(i);
}
if(count>0){
score = score/count;
}
if(score==0){
score = 10;
}
// double diff = (10-Math.round(score));
colorButton(Math.round(score), viewHolder);
// colorButton((int) score);
// for (int j = 9; j >= diff; j--) {
// Button button = buttons.get(j);
// button.setBackgroundColor(Color.WHITE);
// button.setTextColor(Color.BLACK);
// }
}
return convertView;
}
private void colorButton(long givenMark, ViewHolder viewHolder){
for(int i=0; i<buttons.size();i++){
buttons.get(i).setBackgroundColor(Color.WHITE);
}
for (int j = 0; j <= givenMark; j++) {
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： 因此，当我按下按钮3时，所有超过3的颜色都必须变成白色。 或者，当我按下按钮9时，之前的所有按钮必须具有其颜色，并且其前面的按钮必须为白色。 但这不会发生，并且没有错误。 感谢您的任何帮助。

那不是评级栏吗？
OnClickListener是错误的，我的意思是没有正确的侦听器，您的想法是错误的。 封闭的视图是什么？
