Actually i have created an array of buttons,now my question is whether it will be fit in all screen resolution or not..as i have use nexus s device and the here its working fine..i mean to say that all the buttons are arranged in perfect order..more ever when i placed background image to each buttons its work fine..now i doubt whether it works for cheaper device by the same code i have written or i have to do something extra for that.thats means whether it fit for all screen resolution..or not..the code i have written is..

            LinearLayout layoutVertical = (LinearLayout) findViewById(R.id.liVLayout);
            LinearLayout rowLayout=null;

            LayoutParams param = new LinearLayout.LayoutParams(LayoutParams.FILL_PARENT,LayoutParams.FILL_PARENT,1);

            //Create Button
            for (i = 0; i<6; i++){
                rowLayout = new LinearLayout(this);
                rowLayout.setWeightSum(7);
                layoutVertical.addView(rowLayout,param);

                for(j=0;j<7;j++){
                    pBtnDay[i][j]=new Button(this);

                    rowLayout.addView(pBtnDay[i][j],param); 

                    pBtnDay[i][j].setOnLongClickListener(this);                         
                    pBtnDay[i][j].setOnClickListener(this);



                }
            }
            return true;

    Using weightSum is the best solution if you know exactly how many elements you want displayed on your screen, across multiple devices. So if it shows up on, say a HTC Wildfire(LDPI) then it will also show on your Nexus(HDPI).

    As for your second question, I´m assuming you are using View.getHeight() and View.getWidth() to obtain these values. Since your buttons hasn´t actually been drawn yet, Android has not designated dimension values to them, that´s why they turn up 0. If you need the width and height of these buttons in onCreate, then you need to do some math of your own 🙂
