如何使用SimpleAdapter.ViewBinder？ [英] How to use SimpleAdapter.ViewBinder?

问题描述

我有一个复杂的布局列表 R.layout.menu_row 。它由一个进度和文本字段。该适配器使用：

I have a list with a complex layout R.layout.menu_row. It consists of a ProgressBar and a text field. The adapter I use:

   SimpleAdapter simpleAdapter = new SimpleAdapter(this, getData(path),
            R.layout.menu_row, new String[] { "title", "progress" },
            new int[] { R.id.text1,R.id.progressBar1});

适配器知道如何通过其自身而不是 ProgressBars ，所以我写了一个复杂的数据粘合剂处理 TextViews

The adapter knows how to handle TextViews by it self but not ProgressBars, so I wrote a complex data binder:

    SimpleAdapter.ViewBinder viewBinder = new SimpleAdapter.ViewBinder() {
        @Override
        public boolean setViewValue(View view, Object data, String textRepresentation) {
            //here goes the code
            if () {
                return true;
            }
            return false;
        }

现在我被困填充函数内部的映射。我需要设置字符串的值进步来的 setProgress 方法进度。但我没有得到一个处理字符串进步，并在进度。

Now I'm stuck filling the mapping inside the function. I need to set the value of string progress to the setProgress method of the ProgressBar. But I don't get a handle to string progress and to the ProgressBar.

推荐答案

您需要找出是否 ViewBinder 是呼吁进度并设置它的进步（从数据参数（由列中的数据进步你的情况））：

You need to find out if the ViewBinder is called for the ProgressBar and set its progress(from the data parameter(the data from column progress in your case)):

SimpleAdapter.ViewBinder viewBinder = new SimpleAdapter.ViewBinder() {
        @Override
        public boolean setViewValue(View view, Object data, String textRepresentation) {
            if (view.getId() == R.id.progressBar1) {
                // we are dealing with the ProgressBar so set the progress and return true(to let the adapter know you binded the data)
                // set the progress(the data parameter, I don't know what you actually store in the progress column(integer, string etc)).                             
                return true;
            }
            return false; // we are dealing with the TextView so return false and let the adapter bind the data
}

编辑：
我见过你的的addItem 方法，你做的：

temp.put("progress", name);// Why do you set again the name as progress?!?

我觉得你应该设置在这里是进步参数：

temp.put("progress", progress);

然后在 ViewBinder ：

if (view.getId() == R.id.progressBar1) {
   Integer theProgress = (Integer) data;
   ((ProgressBar)view).setProgress(theProgress); 
   return true;
}
