I am trying to put some animations on my buttons in BT using the Grid or Table layout. Wanted to fade the first button's image ultimately I want to fade in and out different buttons but trying to just get this working first. This is what I have below and the first image is not fading out. I can see by the debugging code that I put in, it is going through my code. //if we used a table layout... //add a few empty row at end so scrolling shows enough of bottom margin... if(usingTable){ BT_debugger.showIt(activityName + ":table10"); for(int t = 0; t < 3; t++){ TableRow tr = new TableRow(this); tr.setPadding(0, 0, 0, 0); RelativeLayout buttonBox = new RelativeLayout(this); buttonBox.setMinimumWidth(buttonSize); buttonBox.setMinimumHeight(buttonSize); tr.addView(buttonBox, buttonSize, buttonSize); tableLayout.addView(tr, new TableLayout.LayoutParams(LayoutParams.WRAP_CONTENT, LayoutParams.WRAP_CONTENT)); int xcnt = 1; RelativeLayout box = (RelativeLayout) buttonBoxes.get(xcnt); AlphaAnimation alphaFade = new AlphaAnimation(0.3f, 1.0f); alphaFade.setDuration(500); alphaFade.setFillAfter(true); box.startAnimation(alphaFade); } BT_debugger.showIt(activityName + ":animationstat0"); // invalidate tableLayout... tableLayout.invalidate();

Instead, why not just use [UIView animateWithDuration:] ? Would look something like: UIButton *thisButton = [self.view viewWithTag:1]; [UIView animateWithDuration:.5 animations:^(void){ thisButton.alpha = .3f; }];

Ignore my post - I was thinking in iOS terms

my fault I forgot to put android in the subject
