Android ListView SimpleAdapter支持Bitmap类型图片显示

// 处理simpleAdapter中包括bitmap类型
        adapter.setViewBinder(new ViewBinder() {
            public boolean setViewValue(View view, Object data,
                    String textRepresentation) {
                if (view instanceof ImageView && data instanceof Bitmap) {
                    ImageView image = (ImageView) view;
                    image.setImageBitmap((Bitmap) data);
                    return true;
                }
                return false;
            }
        });

完整示例如下:

listData = this.GetPersonalData();
        adapter = new SimpleAdapter(this, listData,
                R.layout.personal_list_item, new String[] { "label", "image",
                        "arrows", "value" }, new int[] { R.id.personal_label,
                        R.id.personal_img, R.id.list_arrows,
                        R.id.personal_value });

        // 处理simpleAdapter中包括bitmap类型
        adapter.setViewBinder(new ViewBinder() {
            public boolean setViewValue(View view, Object data,
                    String textRepresentation) {
                if (view instanceof ImageView && data instanceof Bitmap) {
                    ImageView image = (ImageView) view;
                    image.setImageBitmap((Bitmap) data);
                    return true;
                }
                return false;
            }
        });

        mainListView.setAdapter(adapter);
private List<Map<String, Object>> GetPersonalData() {
        List<Map<String, Object>> list = new ArrayList<Map<String, Object>>();

        Map<String, Object> map = new HashMap<String, Object>();

        map.put("label",
                this.getResources().getString(R.string.personal_headphoto));
        map.put("image",
                preferences.getString("photo", null) == null ? R.drawable.head
                        : this.StringToBitMap(preferences.getString("photo",
                                null)));//经过上述view.setViewBing之后在put值的时候就可以直接加入BitMap类型图片进行显示了
        map.put("arrows", R.drawable.arrows_right);
        list.add(map);

        map = new HashMap<String, Object>();
        map.put("label", this.getResources().getString(R.string.personal_name));
        map.put("value", "APP测试");
        list.add(map);

        map = new HashMap<String, Object>();
        map.put("label",
                this.getResources().getString(R.string.personal_username));
        map.put("value", "xxx");
        list.add(map);

        map = new HashMap<String, Object>();
        map.put("label",
                this.getResources().getString(R.string.personal_disease));
        map.put("value", preferences.getString("disease", "无"));
        map.put("arrows", R.drawable.arrows_right);
        list.add(map);
        return list;
    }

注:着色部分意思为图片资源我用的base64所以这里边我转化了一下。
