android - Change shape color -


i have imagebutton:

<imagebutton     android:layout_width="100dp"     android:layout_height="100dp"     app:srccompat="@drawable/round_color"     android:layout_below="@+id/lamps_list_room"     android:layout_alignstart="@+id/lamps_list_room"     android:layout_marginstart="69dp"     android:layout_margintop="62dp"     android:id="@+id/color_picker_button"     android:background="@color/colorprimarydark"/>

and shape:

<?xml version="1.0" encoding="utf-8"?> <shape xmlns:android="http://schemas.android.com/apk/res/android">     <solid android:color="#ffffff" />     <corners android:radius="100dp" />     <stroke         android:color="#ffffff"         android:width="2px">     </stroke> </shape>

what best way change solid color of shape?

imagebutton imagebutton = (imagebutton) ((activity) mcontext).findviewbyid(r.id.color_picker_button);  drawable drawable = imagebutton.getbackground(); drawable.setcolorfilter(0xff999999, porterduff.mode.multiply);

the shape still white...

edit:

even when try

drawable drawable = mcontext.getdrawable(r.drawable.round_color);  colorfilter filter = new lightingcolorfilter(color.black, color.black);  if (drawable != null) {     drawable.setcolorfilter(filter); }

it still doesn't work!

this how it, change code accordingly.

gradientdrawable bgshape = (gradientdrawable) getchildat(0).getbackground(); bgshape.setcolor();

Image
i'm using qt framework build graphical user interface. use qgridlayout position qwidgets neatly. gui looks this: my application regularly adds new widgets gui @ runtime. these new widgets not added @ end of qlayout, somewhere in middle. the procedure bit cumbersome. applied on figure above, need take out widg_c , widg_d , ... qgridlayout. next, add widg_x and widg_y , , put other widgets again. how remove widgets qgridlayout: for in reversed(range(mygridlayout.count())): self.itemat(i).widget().setparent(none) ### as long you're dealing small amount of widgets, procedure not disaster. in application display lot of small widgets - perhaps 50 or more! application freezes second while procedure ongoing, annoying user. there way insert widgets somewhere in qlayout, without need take out other widgets? edit: apparently solution qvboxlayout simple. use function insertwidget(..) instead of addwidget(..) . docs can found link: http://doc.qt.io/qt-5/qboxlayou
