Android - add fragment with custom dimensions -
currently, adding fragment using following code.
private void addfragment(fragment fragment, string fragmentname) { log.i("adder", "adding fragment " + fragmentname); fragmenttransaction fragmenttransaction = fragmentmanager.begintransaction(); fragmenttransaction.add(r.id.fragment_container, fragment, fragmentname); fragmenttransaction.commit(); } following code resizing added fragment.
private boolean readjustfragment(fragment fragmenttobeadjusted, fragmentcoordinates fragmentcoordinates) { if (fragmenttobeadjusted != null) { view view = fragmenttobeadjusted.getview(); relativelayout.layoutparams params = new relativelayout.layoutparams(fragmentcoordinates.getwidth(), fragmentcoordinates.getheight()); params.leftmargin = fragmentcoordinates.getx0(); params.bottommargin = fragmentcoordinates.gety0(); view.setlayoutparams(params); view.requestlayout(); return true; } return false; } but instead of adding , resizing, how add fragment custom dimensions (height, width , margins) ?
you can pass desired width height , margin fragment , assign value while inflating view
for example if using frame layout container fragments pass values new instance method
/** * * @param widthindp * @param heightindp * @param leftmargindp * @param topmargindp * @param rightmargindp * @param bottommargindp * @param fragindex * @return */ public static placeholderfragment newinstance(int widthindp, int heightindp, int leftmargindp, int topmargindp, int rightmargindp, int bottommargindp, int fragindex) { placeholderfragment resizablefragment = new placeholderfragment(); bundle args = new bundle(); // test purpose args.putint(index, fragindex); // set width height dynamically args.putint(width, widthindp); args.putint(height, heightindp); // setmargin args.putint(left_margin, leftmargindp); args.putint(right_margin, rightmargindp); args.putint(top_margin, topmargindp); args.putint(bottom_margin, bottommargindp); resizablefragment.setarguments(args); return resizablefragment; } and apply them in oncreateview method. point note here if using frame layout container fragments use framelayout param else exception.
framelayout.layoutparams params = (framelayout.layoutparams) rootview .getlayoutparams(); // set width height params.height = dptopx(getarguments().getint(height)); params.width = dptopx(getarguments().getint(width)); // substitute // parameters left,top, right, bottom params.setmargins(dptopx(getarguments().getint(left_margin)), dptopx(getarguments().getint(top_margin)), dptopx(getarguments().getint(right_margin)), dptopx(getarguments().getint(bottom_margin))); rootview.setlayoutparams(params); output :-
orange background frame layout container , other resized fragments custom margins in same container. can play around layoutparam.gravity property make them go left right, top, bottom , center, bottom- center, top center , on
