我有一个自定义列表视图，我有一些按钮。点击每个按钮，我改变它的颜色，例如。第一个按钮的灰色到红色＆amp;第二个按钮为灰色至绿色，第三个按钮为灰色至蓝色等。
我已经使用了视图保持器模式。当单击按钮时，我没有更改相应按钮的颜色。点击每个按钮只有第一行和第一行。最后一行按钮颜色已更改。
这是我的代码：
public class LocationInspectionAdapter extends
ArrayAdapter<LocationInspectionBean> {
private final Activity context;
private final int layoutResourceId;
private static final int CAPTURE_IMAGE_ACTIVITY_REQUEST_CODE = 100;
ViewHolder holder;
Uri uri;
String fname;
File image, imagesFolder;
Bitmap bp = null;
// static Context c;
View v;
// private Uri fileUri;
Integer count;
private ArrayList<LocationInspectionBean> values = new ArrayList<LocationInspectionBean>();
public LocationInspectionAdapter(Activity context,
int layoutResourceId, ArrayList<LocationInspectionBean> values) {
super(context, layoutResourceId, values);
this.context = context;
this.values = values;
this.layoutResourceId = layoutResourceId;
notifyDataSetChanged();
Log.i("Home", "enter");
}
public class ViewHolder {
TextView componentName, count_text;
ImageView camra, red_circle;
Button clean, dirty, na, dc, notes;
}
GetView方法：
@Override
public View getView(final int position, View convertView, ViewGroup parent) {
select_postion=position;
Log.i("error","select--"+select_postion);
note_pos = position;
View rowView = convertView;
if (convertView == null)
{
LayoutInflater inflater = context.getLayoutInflater();
rowView = inflater.inflate(layoutResourceId, null, true);
holder = new ViewHolder();
holder.componentName = (TextView) rowView
.findViewById(R.id.location_list_row);
holder.clean = (Button) rowView.findViewById(R.id.btn1);
holder.dirty = (Button) rowView.findViewById(R.id.btn2);
holder.dc = (Button) rowView.findViewById(R.id.btn3);
holder.na = (Button) rowView.findViewById(R.id.btn4);
holder.camra = (ImageView) rowView.findViewById(R.id.btn5);
holder.camra.setTag(position);
holder.notes = (Button) rowView.findViewById(R.id.btn6);
holder.count_text = (TextView) rowView
.findViewById(R.id.circle_count);

这不正确，因为它总是首先更新颜色＆amp;最后的观点。
我还打印了每个按钮的索引，我得到了最后一项的正确索引，我得到0指数。请告诉我如何才能改进这一点。
答案 0 :(得分：1)
在OnClick（View v）中，您将视图作为参数，更改其背景颜色，如
v.setBackgroundColor(Color.RED);
答案 1 :(得分：1)
你可以尝试这样的事情:(只有当他们拥有相同的父母时）
d为其他人做同样的事情。
答案 2 :(得分：1)
做这样的事情：
if (location_obj.getInspectionstatus().equalsIgnoreCase("1")) {
holder.clean.setBackgroundColor(Color.parseColor("#1C6614"));
} else{
holder.clean.setBackgroundColor(Color.parseColor("Color_you_want_to_remian_with"));
}
if (location_obj.getInspectionstatus().equalsIgnoreCase("3")) {
holder.dirty.setBackgroundColor(Color.parseColor("#FC4E3B"));
} else{
holder.dirty.setBackgroundColor(Color.parseColor("Color_you_want_to_remian_with"));
}
在getView()中为剩余的if条件执行此操作，然后检查这些更改是否有效
