ViewBinder创建随机内容 [英] ViewBinder creates random content

问题描述

我有一个奇怪的ViewBinder behavoir。所有的工作在TextViews不错。随着的CheckBox（在我的code删除），并自定义部件progressChart值不存储在列表右侧现在的位置，当我向下滚动和/或再升。一切似乎很随意。但TextViews是总是正确的。
这里是我的code：

I have strange behavoir in a ViewBinder. All works good on TextViews. With CheckBoxes (removed in my code) and custom widgets progressChart the values are not stored in the right postion of the List when I scroll down and/or up again. All seems very random. But TextViews are always correct. Here is my code:

SimpleAdapter.ViewBinder viewBinder = new SimpleAdapter.ViewBinder() {
            @Override
            public boolean setViewValue(View view, Object data,
                    String textRepresentation) {
                if (view.getId() == R.id.progress) {
                    ProgressChart progressChart = (ProgressChart) view;

                progressChart.setVisibility(ImageButton.GONE);
                    } else {
                        if (x.substring(0, 1).equals("1")) {
                            int theProgress = Integer.parseInt(x.substring(1));
                            progressChart.setProgressDarkRed(theProgress);
                        }
                }
                if (view.getId() == R.id.textView1) {
                    TextView textView = (TextView) view;
                    textView.setText((String) data);
                }
                return true;
            }
        };
        simpleAdapter.setViewBinder(viewBinder);
        setListAdapter(simpleAdapter);

推荐答案

这是因为鉴于回收。

您需要创建一个对象来保存你的复选框的状态，并在您的适配器设置你的看法。

You need to create an object to hold the status of your checkboxes and set your views from that in your adapter.

我不认为它可以在viewbinder来完成，因为位置不是在传递给它（但说实话，我从来没有尝试过）。

I don't think it can be done in the viewbinder since the position is not passed in to it (but to be honest I've never tried)..

您可能不得不做，在 getView 。

You will probably have to do it in getView.
