Question

我想设置可触摸的图像视图以及如何获得列表视图中每一行的图像视图的位置？

    public View newView(Context context, Cursor cursor, ViewGroup parent) {
        // when the view will be created for first time,
        // we need to tell the adapters, how each item will look
        LayoutInflater inflater = LayoutInflater.from(parent.getContext());
        View retView = inflater.inflate(R.layout.list_shipments, parent, false);


        return retView;
    }


    @Override
    public void bindView(View view, Context context, Cursor cursor) {


    }
}

Answer 1

Cursor或newView时，bindView已定位在确切的行中。您只需设置onClick或OnTouch侦听器：

@Override
public View newView(Context context, Cursor cursor, ViewGroup viewGroup)
{
    LayoutInflater inflater = LayoutInflater.from(parent.getContext());
    View retView = inflater.inflate(R.layout.list_shipments, parent, false);
    ViewHolder holder = new ViewHolder(view);
    view.setTag(holder);
    return view;
}

@Override
public void bindView(View view, final Context context, Cursor cursor)
{
    ViewHolder holder = (ViewHolder) view.getTag();

    holder.image.setOnClickListener(new View.OnClickListener()
    {
        @Override
        public void onClick(View v)
        {
            // do something
        }
    }

ViewHolder的一些代码：

public static class ViewHolder
    {
        private ImageView image;
        public ViewHolder(View view)
        {
            image = (ImageView) view.findViewById(R.id.image);
        }
    }

@anil 这是我的View.OnClickListener

中的代码

holder.img.setOnClickListener(new View.OnClickListener()
        {
            public void onClick(View v)
            {
                String abc = holder.tv1.getText().toString();
                String def = holder.tv2.getText().toString();
                System.out.println(abc + def);

                String lat = abc;
                String lng = def;
                String[] countryValues = getResources().getStringArray(R.array.str_array_country_values);
                String country = SettingsActivity.getPreferencesStringValue(CursorAdapterActivity.this, 
                        SettingsActivity.KEY_COUNTRY_CODE, "");
                String uri = "";

                if (country.equals(countryValues[0])){
                    uri = "http://api.map.baidu.com/marker?location=" + lat + "," + lng + "&zoom=15&title= &content= &output=html";
                }
                else{
                    uri = "https://maps.google.com/maps?q=" + lat + "," + lng + "&z=15";    
                }
                startActivity(new Intent(android.content.Intent.ACTION_VIEW, Uri.parse(uri)));
            }

        });
