android中自定义列表视图中的错误按钮侦听器检测

Question

我有一个自定义列表视图，上面有一些按钮。在点击每个按钮时，我会将其颜色更改为例如第一个按钮的灰色到红色；灰色至绿色表示第二个按钮，灰色至蓝色表示第三个按钮等。

为此，我使用了视图夹模式。当点击按钮时，我不会改变相应按钮的颜色。单击每个按钮时，仅第一行&最后一行按钮的颜色已更改。

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);

                            .findViewById(R.id.circle_count);
                    holder.red_circle = (ImageView) rowView.findViewById(R.id.img_red);
                    // String img = location_obj.getImages();

                            intent = new Intent(getContext(), Notes.class);
                            intent.putExtra("client_id", client_id);
                            intent.putExtra("component_id_note", a);
                            intent.putExtra("inspection_id", inspection_id);
                            intent.putExtra("subClient_id", subclient_id);
                            intent.putExtra("sub_client_name", sub_client_name);
                            context.startActivity(intent);
                            context.overridePendingTransition(R.anim.slide_in,
                                    R.anim.slide_out);
                        }
                    });

这并不正确，因为它总是首先更新颜色&最后一个视图。

我还打印了每个按钮的索引，我得到的最后一个项目的正确索引为0。请告诉我该如何改进。

Answer 1

在OnClick（View v）中，您可以将视图作为参数，并像一样更改其背景颜色

v.setBackgroundColor(Color.RED);

Answer 2

您可以尝试这样的操作：（仅当它们有相同的父级时）

holder.clean.setOnTouchListener(new OnTouchListener() {
                    @Override
                    public boolean onTouch(View v, MotionEvent event) {
                        // TODO Auto-generated method stub
                        index = (Integer)v.getTag();
                        //  Log.i("SYNC", "camera"+String.valueOf(index));

对其他人也要这样做。

这样做：

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()中对if条件的其余部分执行此操作，然后检查这些更改是否有效
