将解析后的列表项添加到另一个列表中

Question

我正在开发一个xml解析应用程序新闻应用程序。

我已经解析了xml文件并将其转换为listView，当我点击新闻时，我会看到有关它的更多详细信息。我想实现“添加到收藏夹”按钮，使其显示在“收藏夹”选项卡的列表中（我已在主要活动的tabhost中实现了收藏夹选项卡），有人可以帮我这样做吗？ （我不知道如何实现操作栏按钮（添加到收藏夹）以及如何通过单击它将其添加到列表视图）。感谢!!!!

这是listItemClicked的代码

package com.example.andrian.jurnaltv;




public class ListItemClicked extends ActionBarActivity {

static Bundle extras;

SectionsPagerAdapter mSectionsPagerAdapter;
static ImageLoader imageLoader;
static DisplayImageOptions options;




ViewPager mViewPager;

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.list_item_clicked);


    mSectionsPagerAdapter = new     SectionsPagerAdapter(getSupportFragmentManager());

    extras = getIntent().getExtras();

    mViewPager = (ViewPager) findViewById(R.id.pager);
    mViewPager.setAdapter(mSectionsPagerAdapter);

    //Setup the ImageLoader, we'll use this to display our images
    ImageLoaderConfiguration config = new     ImageLoaderConfiguration.Builder(this).build();
    imageLoader = ImageLoader.getInstance();
    imageLoader.init(config);

    //Setup options for ImageLoader so it will handle caching for us.
    options = new DisplayImageOptions.Builder()
            .cacheInMemory()
            .cacheOnDisc()
            .build();

}


@Override
public boolean onCreateOptionsMenu(Menu menu) {
    // Inflate the menu; this adds items to the action bar if it is present.
    getMenuInflater().inflate(R.menu.menu_main_activity2, menu);
    return true;
}

@Override
public boolean onOptionsItemSelected(MenuItem item) {
    int id = item.getItemId();

    return id == R.id.action_settings || super.onOptionsItemSelected(item);

}



public class SectionsPagerAdapter extends FragmentPagerAdapter {

    @Override

    @Override
