问题 So, i'm thinking about the usage of percent, example, in margins. We can use overlay to separate our layout by dpi sizes, but why can't we use percentage? Something like that: Display display = getWindowManager().getDefaultDisplay(); float width = display.getWidth(); float height = display.getHeight(); //20% of left margin float imageMarginLeft = ( width * 20 ) / 100; And then set this margin to the image, or whatever element. Is this bad? I just wanna discuss about it. Thanks. 回答1:

问题 I am trying to use setEnabled(false) on a Button to show grey disabled state...

I can't see the Button as grey

问题 I need to implement a button in my app like this I used a SwitchCompat button but the closest I arrived was to this point, having two main problems: 1 - The width of the button does not adjust correctly when screen sizes change (drawable gets cut off, become too small etc), it is important that the width occupies the parent view correctly ( a small linear layout enclosing it) 2 - I was not able to understand how I could get the letters in the Switch Track Is it possible to achieve this result

问题 I'm working on improving my app's UI. And in the design I'm using I have a TextView that will act as a progress bar at certain time. The ruslt should look like this : The thing is that parts of text will change their color while the progress is changing I looked into spannablestring in android it would work if I can find the letters that are covered by the progress ( but I don't think this would be easy/accurate) What I'm planning todo now is to use the following: FrameLayout with :
