android - Add imageview style in code -

i want create few imageviews in array code. try this,but app force stop.

imageview imgs[];     imgs=new imageview[10];     imgs[0].setlayoutparams(lp);     imgs[0].setimageresource(r.drawable.drvo1);     rl.addview(imgs[0]); 

posting logcat helpful when have crash. however, here have never initialized barriers[0] npe when try run function on like

 barriers[0].setlayoutparams(lp); 

you initialize array

imgs=new imageview[10]; 

but not first element. need like

imageview imgs[]; imgs=new imageview[10]; imgs[0] = new imageview(this)  // initialize here somehow imgs[0].setlayoutparams(lp); imgs[0].setimageresource(r.drawable.drvo1); rl.addview(imgs[0]);
