Mam niestandardowy widok listy. Muszę wyświetlać dane z serwera WWW. Muszę zaimplementować wyszukiwanie na podstawie danych wejściowych z EditText. Każdy wiersz w ListView zawiera obraz, tytuł i wiadomość. Zmiany obrazu na podstawie odpowiedzi z serwera WebServer. Spójrz na kod.

class CustomListView extends ArrayAdapter {

Context context;
LayoutInflater mInflater;
ArrayList<PostData> mPostingData = null;
private Bitmap mIcon1;
private Bitmap mIcon2;
private Bitmap mIcon3;
PostData mp ;

public  CustomListView(Context c)
{
     super(c, 0);
    mInflater = (LayoutInflater)c.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
    mIcon1 = BitmapFactory.decodeResource(c.getResources(), R.drawable.text_icon);
    mIcon2 = BitmapFactory.decodeResource(c.getResources(), R.drawable.image_icon);
    mIcon3 = BitmapFactory.decodeResource(c.getResources(), R.drawable.video_icon);
}   

public int getCount() {
    // TODO Auto-generated method stub
    if(mPostingData!=null){
        return mPostingData.size();
    }else{
        return 0;
    }
}

 public void setData(ArrayList<PostData> mPpst) {

    mPostingData = mPpst;
}


public Object getItem(int arg0) {
    // TODO Auto-generated method stub
    return arg0;
}

public View getView(int position, View convertView, ViewGroup parent) {
     ViewHolder holder;
    ///int type = getItemViewType(arg0);
     Log.i("Aru","get View");
    if(mPostingData == null ){

        return null;
    }

            if (convertView == null) {
                convertView = mInflater.inflate(R.layout.listviewimg, null);
                convertView.setLayoutParams(new AbsListView.LayoutParams(LayoutParams.FILL_PARENT,
                        LayoutParams.WRAP_CONTENT));
                // Creates a ViewHolder and store references to the two children views
                // we want to bind data to.
                holder = new ViewHolder();
                holder.ll=(LinearLayout) convertView.findViewById(R.id.lvid);
                holder.text = (TextView) convertView.findViewById(R.id.texttitle);
                holder.text2 = (TextView) convertView.findViewById(R.id.tvst);
                holder.icon = (ImageView) convertView.findViewById(R.id.llimage);

                convertView.setTag(holder);
            } else {

                holder = (ViewHolder) convertView.getTag();
            }

            mp = mPostingData.get(position);

            String title = mp.mType;

            if(mp.mTitle!=null && Name.equals(mp.mPostedBy )){
                title = mp.mTitle+" "+title;
                //holder.text.setBackgroundColor(Color.WHITE);
                holder.ll.setBackgroundResource(R.drawable.listbkgme);
                holder.text.setText(title);
            }
            else if(mp.mTitle!=null && Name!=mp.mPostedBy)
            {
                title = mp.mTitle+" "+title;
           holder.text.setText(title);
            }


            if(mp.mMessage!=null && Name.equals(mp.mPostedBy )){

                holder.ll.setBackgroundResource(R.drawable.listbkgme);
                holder.text2.setText(mp.mMessage);

            }
            else if(mp.mMessage!=null && Name!=(mp.mPostedBy))
            {
                holder.text2.setText(mp.mMessage);
            }


            if(mp.mImageUrl!=null ){

                holder.icon.setImageBitmap(mIcon2);
            }else if(mp.mVideoUrl!=null){
                holder.icon.setImageBitmap(mIcon3);
            }else{
                holder.icon.setImageBitmap(mIcon1);
            }
       return convertView;
}
 class ViewHolder {
    TextView text;
    TextView text2;
    ImageView icon;
    LinearLayout ll;
}
public long getItemId(int position) {
    // TODO Auto-generated method stub
    return position;
}

}

Wyślij klasę danych

 class PostData {
String mID; 
String mPostedBy;
String mTitle;
String mMessage;
String mImageUrl;
String mVideoUrl;
String mType ;
boolean me=false;

}

Sortowanie na podstawie tytułu. Jak mogę przeszukiwać widok listy na podstawie tytułu?

    search= (EditText) findViewById(R.id.searchbox);
     search.addTextChangedListener(new TextWatcher() {

         public void onTextChanged(CharSequence s, int start, int before, int count) {
             final String searchString=search.getText().toString();
               int textLength=searchString.length();



               Collections.sort(
                       mTempPost, 
                       new Comparator<PostData>() 
                       {



                        public int compare(PostData lhs, PostData rhs) {

                             System.out.println("........................"+lhs.mTitle+" "+rhs.mTitle);

                              return lhs.mTitle.compareTo(rhs.mTitle);
                        }


                       }
                     );

                         mCustomListView.notifyDataSetChanged();

         }

         public void beforeTextChanged(CharSequence s, int start, int count,
             int after) {


           }

           public void afterTextChanged(Editable s) {

              // mCustomListView.notifyDataSetChanged();
           }
          });
