Добавить элемент из спискаView в другой listView

Question

Я хочу создать кнопку добавления избранных действий в новостях, а если нажать кнопку, добавьте новость в новый адаптер списка на вкладке «Избранное», вы можете помочь мне воспользовавшись кнопкой и скажите, как создать новый список?

вот мой код: (отображение щелкнутой новости)

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 { 

     public SectionsPagerAdapter(FragmentManager fm) { 
      super(fm); 
     } 

     @Override 
     public Fragment getItem(int position) { 
      return PlaceholderFragment.newInstance(position + 1); 
     } 

     @Override 
     public int getCount() { 
      return 2; 
     } 

     @Override 
     public CharSequence getPageTitle(int position) { 
      Locale l = Locale.getDefault(); 
      switch (position) { 
       case 0: 
        return getString(R.string.title_section4).toUpperCase(l); 
       case 1: 
        return getString(R.string.title_section5).toUpperCase(l); 
      } 
      return null; 
     } 
    } 


    public static class PlaceholderFragment extends Fragment { 


     private static final String ARG_SECTION_NUMBER = "section_number"; 


     public static PlaceholderFragment newInstance(int sectionNumber) { 
      PlaceholderFragment fragment = new PlaceholderFragment(); 
      Bundle args = new Bundle(); 
      args.putInt(ARG_SECTION_NUMBER, sectionNumber); 
      fragment.setArguments(args); 
      return fragment; 
     } 

     public PlaceholderFragment() { 
     } 

     @Override 
     public View onCreateView(LayoutInflater inflater, ViewGroup container, 
           Bundle savedInstanceState) 
     { 

      View rootView = inflater.inflate(R.layout.fragment_list_item_clicked, container, false); 


      TextView pDate = (TextView) rootView.findViewById(R.id.textView); 
      pDate.setText(extras.getString("pdate")); 


      TextView ptitle = (TextView) rootView.findViewById(R.id.section_label); 
      ptitle.setText(extras.getString("pname")); 


      TextView pnText = (TextView) rootView.findViewById(R.id.textView2); 
      pnText.setText(extras.getString("pText")); 




      //Setup a listener we can use to swtich from the loading indicator to the Image once it's ready 
      ImageLoadingListener listener = new ImageLoadingListener(){ 



       @Override 
       public void onLoadingStarted(String arg0, View arg1) { 
        // TODO Auto-generated method stub 

       } 

       @Override 
       public void onLoadingCancelled(String arg0, View arg1) { 
        // TODO Auto-generated method stub 

       } 

       @Override 
       public void onLoadingComplete(String arg0, View arg1, Bitmap arg2) { 
        // i/ndicator.setVisibility(View.INVISIBLE); 
        // iconImg.setVisibility(View.VISIBLE); 
       } 
       @Override 
       public void onLoadingFailed(String arg0, View arg1, FailReason arg2) { 
        // TODO Auto-generated method stub 

       } 

      }; 

      //Load the image and use our options so caching is handled. 
      final ImageView iconImg = (ImageView) rootView.findViewById(R.id.imageView); 
      imageLoader.displayImage(extras.getString("pImage"), iconImg, options, listener); 



      return rootView; 
     } 
    } 

} 

вот код для ListView:

public class Noutati1 extends Activity { 

private SitesAdapter mAdapter; 
private ListView sitesList; 
private Context context; 



@Override 
protected void onCreate(Bundle savedInstanceState) { 


    super.onCreate(savedInstanceState); 
    Log.i("StackSites", "OnCreate()"); 
    setContentView(R.layout.noutati); 

    context = this; 

    //Get reference to our ListView 
    sitesList = (ListView)findViewById(R.id.sitesList); 




    sitesList.setOnItemClickListener(new  AdapterView.OnItemClickListener() { 

     @Override 
     public void onItemClick(AdapterView<?> parent, View v, int pos,long id) { 
     String Title = mAdapter.getItem(pos).getName(); 
     String nDate = mAdapter.getItem(pos).getnDate(); 
     String ImageUrl = mAdapter.getItem(pos).getImgUrl(); 
     String Text = mAdapter.getItem(pos).getnText(); 
     String VideoUrl = mAdapter.getItem(pos).getVideoUrl(); 
     Intent i = new Intent(context, ListItemClicked.class); 
     //i.setData(Uri.parse(VideoUrl)); 

     i.putExtra("pname", Title); 
     i.putExtra("pdate", nDate); 
     i.putExtra("pText", Text); 
     i.putExtra("pImage", ImageUrl); 


     startActivity(i); 

    } 

    }); 




    /* 
    * If network is available download the xml from the Internet. 
    * If not then try to use the local file from last time. 
    */ 

    if(isNetworkAvailable()){ 
     Log.i("StackSites", "starting download Task"); 
     SitesDownloadTask download = new SitesDownloadTask(); 
     download.execute(); 
    }else{ 
     mAdapter = new SitesAdapter(getApplicationContext(), -1, SitesXmlPullParser.getStackSitesFromFile(Noutati1.this)); 
     sitesList.setAdapter(mAdapter); 
    } 

} 

//Helper method to determine if Internet connection is available. 
private boolean isNetworkAvailable() { 
    ConnectivityManager connectivityManager 
      = (ConnectivityManager) getSystemService(Context.CONNECTIVITY_SERVICE); 
    NetworkInfo activeNetworkInfo = connectivityManager.getActiveNetworkInfo(); 
    return activeNetworkInfo != null && activeNetworkInfo.isConnected(); 
} 

/* 
* AsyncTask that will download the xml file for us and store it locally. 
* After the download is done we'll parse the local file. 
*/ 
private class SitesDownloadTask extends AsyncTask<Void, Void, Void> { 

    @Override 
    protected Void doInBackground(Void... arg0) { 
     //Download the file 
     try { 
       Downloader.DownloadFromUrl("http://www.link..../news.xml", openFileOutput("news.xml", Context.MODE_PRIVATE)); 
     } catch (FileNotFoundException e) { 
      e.printStackTrace(); 
     } 

     return null; 
    } 

    @Override 
    protected void onPostExecute(Void result){ 
     //setup our Adapter and set it to the ListView. 
     mAdapter = new SitesAdapter(context, -1, SitesXmlPullParser.getStackSitesFromFile(Noutati1.this)); 
     sitesList.setAdapter(mAdapter); 
     Log.i("StackSites", "adapter size = " + mAdapter.getCount()); 
    } 
} 

} 

Answer 1

кнопку Вы можете добавить в макет в Recyclerview или ListView. Затем установите действие ClickItemListener. Когда вы нажимаете кнопку добавления, вы можете сохранить эти данные в строке, которую вы нажали, до Shared Preferences или Sqlite. Когда вы открываете вкладку «Избранное» и загружаете данные из данных, которые вы сохранили.
