问题 Does the new Android Material Design support old version of android such as 3.0 or 2.1? if it supports how would it look like? as a real material design or just as old design? I am about to update my app with material design theme so is there anybody who already has done this? 回答1: As far as material design as a concept goes, yes you can do it all today. Some aspects of it would require a lot more work on your part (for example, imitating the new action bar design guidelines), whereas some

问题 Background On my app, when I've updated to the new support library and also tried on Lollipop, I've noticed a weird issue: when clicking on the overflow button of the action bar (or even the new Toolbar class) will show the popup menu on top of the action bar, hiding other action items, as such: Here, the action items that got hidden are uninstallation and sharing. The problem I've tried to avoid this issue, by ovverriding the style of the overflow menu, but nothing has helped. Not only that,

问题 I'm using the new support TabLayout from Android. The thing is that I wanted to use selectors to change the icon when a tab is selected.

问题 So we're trying to create an across activity image transition from an image in a ListView, to an image in a ViewPager gallery.In doing this transition we're seeing the animation happen before the ViewPager finishes loading/drawing. This causes the image on the ViewPager to flash making the animation look bad. As a test we put an image overtop to fake the look of the ViewPager being loaded. We then transition from the image in the ListView to this 'dummy' ImageView, and then hide it after the

问题 I find out that we can use cool flags that scroll both toolbar and even content by using layout_scrollFlags . In my case, I have a layout like this: <android.support.design.widget.CoordinatorLayout xmlns:android="http://schemas.android.com/apk/res/android" xmlns:app="http://schemas.android.com/apk/res-auto" android:layout_width="match_parent" android:layout_height="match_parent"> <android.support.design.widget.AppBarLayout android:layout_width="match_parent" android:layout_height="wrap

问题 In the latest Material Design documentation (https://www.google.com/design/spec/what-is-material/elevation-shadows.html#elevation-shadows-elevation-android-) an exhaustive set of UI elements are referenced with their respective elevation (z-index in dp). For example a switch is elevated by 1dp , while a dialog is elevated by 24dp . Currently Google's list of UI elements uses 10 different elevation levels. Since the elevation decides the shadow of the element, we'll need 10 different shadows.
