Tengo una vista de lista personalizada. Tengo que mostrar los datos del servidor web. Necesito implementar la búsqueda basada en la entrada de EditText. Cada fila en ListView contiene imagen, título y mensaje. Cambios de imagen basados ​​en la respuesta del servidor web. Echa un vistazo al código.

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;
}

}

Clase de datos post

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

}

Clasificación basada en el título. ¿Cómo puedo buscar en la vista de lista en función del título?

    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();
           }
          });
