Set the left-side display for Gallery

The image in Gallery is displayed in the center by default, but in many cases we need it to be displayed on the left. In this way, we can simply set the left value of gallery to the negative value, the method is as follows: drawable = categoryitem. getcategorys (). get (0 ). getimage (); displaymetrics metrics = new displaymetrics (); activity. getwindowmanager (). getdefadisplay display (). getmetrics (metrics); marginlayoutparams MLP = (marginlayoutparams) Gallery. getlayoutparams (); MLP. setmargins (-(metrics. widthpixels/2 + drawable. getintrinsicwidth (), MLP. topmargin, MLP. rightmargin, MLP. bottommargin); Gallery. setlayoutparams (MLP );
