    float scalefactor = getresources().getdisplaymetrics().density * 100;     number = getwindowmanager().getdefaultdisplay().getwidth();     columns = (int) ((float) number / (float) scalefactor); 

when use code, generates same number of columns regardless of width of textview. eg. getting output like,

i want textview adjust automatically in first row since space available in first row. in short, want column count increment stop once width of phone reached. tried below code,

    int static totaltextarea ;     totaltextarea = totaltextarea + widths; //widths text area of textview     if(totaltextarea <=number) //number screen width      {      columncount++      }
