Question

嗨我正在使用合并适配器创建列表视图。但我在标题方面遇到了一些问题。它们似乎独立于列表滚动，通常只是捕捉到页面顶部。我如何得到它以使标题保持原位？或者是否有人不会导致这种情况？

继承我的代码

arrayAdapter = new ArrayAdapter<String>(this, R.layout.single_item, newsList);
arrayAdapter2 = new ArrayAdapter<String>(this, R.layout.single_item, newsList2);
arrayAdapter3 = new ArrayAdapter<String>(this, R.layout.single_item, newsList3);


 RelativeLayout layout = new RelativeLayout(this);
 RelativeLayout.LayoutParams labelLayoutParams = new RelativeLayout.LayoutParams(
            RelativeLayout.LayoutParams.FILL_PARENT, RelativeLayout.LayoutParams.FILL_PARENT);
    layout.setLayoutParams(labelLayoutParams);

    ImageView mImage = new ImageView(this);
    mImage.setBackgroundResource(R.drawable.titlerect);        
    layout.addView(mImage,labelLayoutParams);

    TextView latestFixtures;         
       latestFixtures = new TextView(this);
       latestFixtures.setText("Latest League Fixture");
       layout.addView(mImage,labelLayoutParams);


    ListView list = getListView();
       list.setTextFilterEnabled(true);




setListAdapter (arrayAdapter);




    adapter = new MergeAdapter();
    adapter.addView(layout);
    adapter.addAdapter(arrayAdapter);
    adapter.addView(layout);
    adapter.addAdapter(arrayAdapter2);
    adapter.addView(layout);
    adapter.addAdapter(arrayAdapter3);
    setListAdapter(adapter);

}

Answer 1

使用MergeAdapter 或使用addHeaderView()，而不是两者都使用。

Android标题视图分别滚动到列表视图
