hello . i am trying to make an android's UI programmatically.
Part 1 :
indeed at the first step i get the data from web server and save it in array . the first step works very well and it doesn't have any problem .
here this is the code of first step :

protected String doInBackground(String...Urls){
			String Data="";
			HttpURLConnection urlConnection = null;	
			try{
	    	    URL myUrl=new URL("http://10.0.2.2:80/Urgence/Default.aspx?type="+Type);
	    	    urlConnection = (HttpURLConnection)myUrl.openConnection();		
	    		BufferedReader in = new BufferedReader (new InputStreamReader(urlConnection.getInputStream()));    		
	    		String temp="";	
	    		// Data is used to store Server's Response 
	    		while((temp=in.readLine())!=null)
	    		{    			
	    			 Data=Data+temp;   		
	    		}    
			}
			catch(Exception ex){
				Log.d("Er>doInBackground", ex.toString());
				urlConnection.disconnect();	
			}
			finally{
				urlConnection.disconnect();
				}
				return Data;// it sends Result to onPostExcute 			
		}
		protected void onPostExecute(String Data){
			try{
			serverResponsesArray=Data.split("/",3);
			makeItems(serverResponsesArray);
			dialog.cancel();			
			}
			catch(Exception ex){
				Log.d("Er>onPostExecute",ex.toString());
			}
			finally{
			 dialog.cancel();
			}
	    }

part 2 :
in second step i want to make an UI and show my data in some Rows !
if you notice to my code you can realize that i use a TextView to show array's members(subject,writer,main text,Date) . at first i use TextView for showing (Date,writer and subject) and after that i use it to show the main text . now it shows Date , Time and writer but it doesn't show the main text ! amazingly it increases the row's height but i cant see any main text ! i have debugged my code 3 times but it didnt have any problem !! now do me a favor and tell me what is the exact problem in my code ?! thanks in advance
code of second part :

public void makeItems(String Data[]){
		int marginHorizontal=(int)getResources().getDimension(R.dimen.lpll_marginhor);// it is used to set llc's margin
		int marginVertical=(int)getResources().getDimension(R.dimen.lpll_marginver);// it is used to set margin
		int txtMargin=(int)getResources().getDimension(R.dimen.lptvmargin);// it is used to set TextView's margin
		Typeface face=Typeface.createFromAsset(getAssets(),"Font/ADOBEARABIC-REGULAR.OTF");
		LayoutParams lpll;//		
		LinearLayout llm=(LinearLayout)findViewById(R.id.contentMainLLayout);//main linear Layout
		LinearLayout llc;// Linear Layout as a Item's Row
		TextView tv;
		LayoutParams lptv;// it is used to set TextView's LayoutParams		
		String separateDataArray[]=new String[4];
		try{
		for(int i=0;i<=2;i++){
			separateDataArray=Data[i].split("-",4);//
			llc=new LinearLayout(this);
			llc.setOrientation(LinearLayout.HORIZONTAL);
			lpll= new LinearLayout.LayoutParams(LayoutParams.MATCH_PARENT,LayoutParams.WRAP_CONTENT);
			lpll.setMargins(marginVertical,marginHorizontal,marginVertical,marginHorizontal);
			llc.setLayoutParams(lpll);
			if(i%2==0){
			llc.setBackgroundColor(getResources().getColor(R.color.bcfbc8));	
			}
			else{
				llc.setBackgroundColor(getResources().getColor(R.color.bcd1fb));	
			}
			lptv=new LinearLayout.LayoutParams(LayoutParams.MATCH_PARENT,LayoutParams.WRAP_CONTENT);//
			lptv.setMargins(txtMargin,txtMargin,txtMargin,txtMargin);//
			// tv shows date , writer and subject
			tv=new TextView(this);//			
			tv.setTypeface(face);//
			tv.setTextSize(getResources().getDimension(R.dimen.content_item_txtsize));//*						
			tv.setText(" موضوع : "+separateDataArray[0]+"\n"+" نویسنده : "+separateDataArray[2]+"\n"+" تاریخ : "+separateDataArray[1]);//			
			tv.setLayoutParams(lptv);			
			llc.addView(tv);
			// new tv shows main text 
			tv=new TextView(this);
			tv.setTypeface(face);//
			tv.setTextSize(getResources().getDimension(R.dimen.content_item_txtsize));//*	
			tv.setGravity(Gravity.CENTER);
			tv.setText(separateDataArray[3]);			
			tv.setLayoutParams(lptv);	
			llc.addView(tv);			 
			//
			llm.addView(llc);
			}
		}
		catch(Exception ex){
			Log.d("Er>makeItems",ex.toString());
		}
