-all information are comming from xml which is available on server means
1- number of button on screen
2- size, background images of screen and buttons,text on button each and everythings coming from
server
so we can’t use xml for creating layout.I have been comleted tabbar and when I am creating buttons that is not taking any properties code used by me is as-

TabHost tabHost = getTabHost();
        TabHost.TabSpec spec;
        Intent intent;
        int id = getResources().getIdentifier("com.correlation.edumationui:drawable/" + img, null, null);
        intent = new Intent().setClass(this, HomeScreen.class);//HomeScreen.class);
        Bundle objbundle = new Bundle();
        objbundle.putSerializable("screen", mscreen);
        intent.putExtras(objbundle);
        spec = tabHost.newTabSpec("title").setIndicator(title,getResources().getDrawable(id))
                      .setContent(intent);
        tabHost.addTab(spec);   

for creating button i am using this code–in homescreen Activity( HomeScreen.class)

LinearLayout buttonsView = new LinearLayout(this);
    buttonsView.setOrientation(LinearLayout.VERTICAL);

    for (int r = 0; r < 6; ++r)
    {
     Button btn = new Button(this);
     btn.setText("A");
     btn.setHeight(30);
     btn.setWidth(224);
     btn.setPadding(10,10,10,10);
     LinearLayout.LayoutParams lp = new LinearLayout.LayoutParams(LinearLayout.LayoutParams.FILL_PARENT, LinearLayout.LayoutParams.FILL_PARENT); // Verbose!
     lp.weight = 1.0f; // This is critical. Doesn't work without it.
     buttonsView.addView(btn, lp);
    }
    ViewGroup.LayoutParams lp = new ViewGroup.LayoutParams(ViewGroup.LayoutParams.FILL_PARENT, ViewGroup.LayoutParams.FILL_PARENT);
    setContentView(buttonsView, lp);

give me your valuable help….

Answer 1

Instead of

  LinearLayout.LayoutParams lp = new LinearLayout.LayoutParams(LinearLayout.LayoutParams.FILL_PARENT, LinearLayout.LayoutParams.FILL_PARENT); // Verbose!
 lp.weight = 1.0f; // This is critical. Doesn't work without it.
 buttonsView.addView(btn, lp);

Use

   LinearLayout.LayoutParams lp = new LinearLayout.LayoutParams(30, 224); // Verbose!
   lp.weight = 1.0f; // This is critical. Doesn't work without it.
   buttonsView.addView(btn,lp);

to reflect the width and height of buttons in layout parameters.
