我在我的主要布局中使用自定义列表视图https://github.com/NikolaDespotoski/DoubleTapListViewHandler/tree/master/src/com/nikola/despotoski/doubletaplistview但问题是这将创建自定义programicaly布局但在我的代码中我已经设置了内容setContentView（R.layout.bid）;那么如何在我的主布局中添加新的自定义布局？帮帮我怎么办？

 private CustomListView bidlist = null;


public class BidSchema extends BackBaseActivity  implements OnItemDoubleTapLister {

     @Override
     protected void onCreate(Bundle savedInstanceState) {
          // TODO Auto-generated method stub
          super.onCreate(savedInstanceState);
          setContentView(R.layout.bid);

          bidlist = new CustomListView(this);
          bidlist.setLayoutParams(new ViewGroup.LayoutParams(LayoutParams.FILL_PARENT, LayoutParams.FILL_PARENT));
          setContentView(bidlist);
          back = (ImageView) findViewById(R.id.bidback);
          bottomlayout = (RelativeLayout)findViewById(R.id.bottom_layout);
          scroll_down = (ImageView) findViewById(R.id.down);
          scroll_up = (ImageView) findViewById(R.id.up);

Answer 1

如果您已实现自定义Listview，则应更改此内容。

      setContentView(R.layout.bid);

      bidlist = new CustomListView(this);
      bidlist.setLayoutParams(new ViewGroup.LayoutParams(LayoutParams.FILL_PARENT, LayoutParams.FILL_PARENT));
      setContentView(bidlist);

到

      bidlist = new CustomListView(this);
      bidlist.setLayoutParams(new ViewGroup.LayoutParams(LayoutParams.FILL_PARENT, LayoutParams.FILL_PARENT));
      setContentView(bidlist);

的更新： 的

RelativeLayout rootLayout = (RelativeLayout) findViewById(R.id.layout); bidlist = new CustomListView(this); RelativeLayout.LayoutParams rlp = new RelativeLayout.LayoutParams(LayoutParams.MATCH_PARENT, LayoutParams.MATCH_PARENT)); lp.addRule(RelativeLayout.ALIGN_PARENT_BOTTOM); rootLayout.addView(bidlist, rlp);

因为你不能两次调用setContentView（）。因此，您必须将其添加到父相对布局中。所以检查一下。

Answer 2

你没有setContentView 如果主要活动显示已发布xml，只需使用Adapter实现baseAdapter，然后只使用listview.setAdapter（你制作适配器）

Answer 3

如下所示向您的父id提供RelativeLayout，以便稍后向此布局添加新视图...

<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:background="@drawable/bg2"
    android:id="@+id/layout" >

    ..........

</RelativeLayout >

现在，将您的bidlist添加到父布局，如下所示......

RelativeLayout rootLayout = (RelativeLayout) findViewById(R.id.layout);

bidlist = new CustomListView(this);

RelativeLayout.LayoutParams lp = new RelativeLayout.LayoutParams(LayoutParams.FILL_PARENT, LayoutParams.FILL_PARENT));
lp.addRule(RelativeLayout.ALIGN_PARENT_BOTTOM);

rootLayout.addView(bidlist, lp);

如何在我的主布局中显示自定义布局？
