Question

我有一个使用BaseAdapter类的自定义listView。我有一个包含HashMaps列表的数组。那些Hashmaps（String，Object）包含位图和一些字符串（这些字符串可能包含HTML标记）。

如果我不在我的Intent代码上使用putExtra - 或者putExtra（“String”，“String”），OnItemClickListener动作运行良好。但是，当我在putExtra中加载hashMap时，它会转到上一页而不是下一页。还有一个尴尬的事情，如果位置等于1，它会毫无问题地进入下一页。否则（0,2,3,4,5,6 ..）它会回到上一页并处于调试模式;在performItemClick操作上，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);
    }

logcat的：

Answer 1

我猜你没有正确检索数据。

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

Answer 2

我在hashMaps上匹配数据并解决了我的问题。

关键在于它正在处理位置1，而不是在我阵列的其他位置上工作。所以我比较了哈希图的数据，并意识到位图的分辨率是不同的 - 300x300和480x480。 480像素太大而无法发送到另一页。

但是仍然想知道如果需要太大的位图可以做些什么。

谢谢
