android - 调用addView()时MergeAdapterDemo崩溃

Question

我正在尝试运行commonsguy的MergeAdapterDemo。当我注释掉对addView的调用时，代码将编译并运行良好。例如，运行良好:

public void onCreate(Bundle icicle) {
    super.onCreate(icicle);
    setContentView(R.layout.main);

    adapter=new MergeAdapter();
    arrayAdapter=buildFirstList();
    adapter.addAdapter(arrayAdapter);
    //adapter.addView(buildButton(), true);
    adapter.addAdapter(buildSecondList());
    //adapter.addView(buildLabel());
    adapter.addAdapter(buildSecondList());

但是，这将崩溃:

public void onCreate(Bundle icicle) {
    super.onCreate(icicle);
    setContentView(R.layout.main);

    adapter=new MergeAdapter();
    arrayAdapter=buildFirstList();
    adapter.addAdapter(arrayAdapter);
    adapter.addView(buildButton(), true);
    adapter.addAdapter(buildSecondList());
    adapter.addView(buildLabel());
    adapter.addAdapter(buildSecondList());

这是当崩溃发生时的调用堆栈:

Thread [<1> main] (Suspended (exception NoClassDefFoundError))  
    MergeAdapter.addViews(List, boolean) line: 101  
    MergeAdapter.addView(View, boolean) line: 78

    ZygoteInit.main(String[]) line: 597 
    NativeStart.main(String[]) line: not available [native method]

我正在使用位于他页面下载部分的预建.jar文件。

关于如何使它工作的任何建议？谢谢!

101行是

 addAdapter(new SackOfViewsAdapter(views));

但是您没有 SackOfViewsAdapter类。

https://github.com/commonsguy/cwac-merge/blob/master/README.markdown说:

This project requires the CWAC SackOfViewsAdapter. A copy of a compatible JAR can be found in the libs/ directory of the project, though you are welcome to try newer ones, or ones that you have patched yourself.

因此，您还需要在项目中包括该库。
