Hi,
Below is the link which shows how my UI looks:
http://i56.tinypic.com/6p89q8.jpg
You can see those articles now. Article are coming from RSS of blog.
So i m making question more simpler:
I wrote code this way as follows: (Im giving code in short)
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.articleslist);
dialog = ProgressDialog.show(Articles.this, "","Loading. Please
wait...", true);
new InsertDataTask().execute(this);
}
private class InsertDataTask extends AsyncTask<Context, Void,
ArrayList> {
private Context context;
protected Cursor doInBackground(final Context... args){
//fetch all the data from db and out it in ArrayList and return
it
}
protected void onPostExecute(final ArrayList c){
//now here is inserted for loop for rendering those
articles in UI
tablev = findViewById(R.id.articleslist);
for(){
tr = new TableRow(context);
tr.setLayoutParams(new
LayoutParams( LayoutParams.FILL_PARENT, LayoutParams.WRAP_CONTENT));
tr.setClickable(true);
tr.setFocusable(true);
// code now create textviews and imageviews
and insert those image into tr
//Finally the tr is inserted into table
tablev.addView(tr);
}
}
When i execute the code.
Because that for loop takes 2/3 seconds to render the UI. My UI gets
hangs for those 2/3 seconds
I think you are clear now
