无法转到下一页

Question

我有一个自定义listView，它使用BaseAdapter类。我有一个数组，它有一个HashMaps列表。这些Hashmap (String，Object)包括位图和一些字符串(这些字符串中可能有HTML标记)。

如果我没有在我的意图代码上使用putExtra -或者putExtra("String"，"String")，那么putExtra操作就能很好地工作。但是，当我在hashMap中加载putExtra时，它会转到上一页而不是下一页。还有一件很尴尬的事，就是如果位置等于1，就会转到下一页，没有任何问题。否则(0，2，3，4，5，6.)它返回到上一页并处于调试模式；在performItemClick操作中，mOnItemClickListener在AdapterView.java中返回null。

这是我的代码：

    // Menu Action
    @Override
    public void onItemClick(AdapterView<?> parent, View view, int position, long id) {
        Intent intent = new Intent(ServicesAndProducts.this, ServicesAndProductsDetail.class);
        HashMap<String, Object> map = servicesAndProductsList.get(position);
        intent.putExtra("SelectedMap", map);
        //intent.putExtra("String", "Esra"); // is working

        //Bundle extras = new Bundle();
        //extras.putSerializable("SelectedMap", servicesAndProductsList.get(position));
        //extras.putString("Title", title);
        //intent.putExtras(extras);
        startActivity(intent);
    }

Answer 1

我在hashMaps上匹配数据并解决了我的问题。

关键是它是在位置1上工作，而不是在我数组的其他位置上工作。因此，我比较了hashmap的数据，发现位图的分辨率是不同的- 300x300和480x480。480像素太大，无法发送到另一个页面。

但仍在想，如果需要太大的位图，还能做些什么。

谢谢

Answer 2

我想你没有正确地检索数据。

// To get the object in second Activity
getIntent().getSerializableExtra("SelectedMap");
