android-5.0-lollipop

问题 I'm trying to use RecyclerView in my application with lots of data in it and would like to make a fast scroll for it, just like for the ListView . Approach from this answer worked for me with ListView , but does not work for the RecyclerView . Even if I set fast scroll to true in RecyclerView layout, it still does not work: <android.support.v7.widget.RecyclerView android:id="@+id/recycler_view" android:scrollbars="vertical" android:layout_width="match_parent" android:layout_height="match

问题 I just ordered a Nexus 9 and will be using it to program. Has anyone tried to run Terminal IDE on Nexus 9 or any other devices using Android 5.0 Lollipop? 回答1: The "links" browser included with Terminal IDE ran fine on my Nexus 5 under KitKat, but it crashes with the PIE error mentioned under Lollipop. Other than that, Terminal IDE has performed flawlessly for me, for about a year now. Sorry--forgot to add: Terminal IDE under Lollipop is "stopped" if started with the Android keyboard, or

Please help me to short out from the problem. Thanks :) <android.support.v7.widget.CardView android:layout_width="match

问题 To add the dividers between disabled items (not clickable) in ListView for Android previous to Lollipop I override adapter's method areAllItemsEnabled() to return true. But now in Lollipop this method doesn't fix the problem. The dividers are invisible in ExpandableListView too. Is there a way to fix this problem without adding the divider in my item layout? 回答1: We ended up adding two Views of 1dp to fake the divider and checking on version to set Visibility. The problem is worse. We also

问题 Since Android Lollipop, we have now an API for accessing apps usage stats. However, your app must be granted those permissions by the user. I know that for redirecting the user to those settings using Settings.ACTION_USAGE_ACCESS_SETTINGS. Now, my question is how do you know the user has granted you those permissions so that you can stop redirecting him to the settings. Thanks! 回答1: you can simply query usagestats with daily interval and end time the current time and if nothing is returned

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 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 TL;DR Why this transition does not start from the expected place? That is, the place where is the CardView. Platform/Deps: Android Studio 1.0-RC2, TargetSdk 21, MinSdk 21, AppCompat-21.0.2, CardView-21.0.2, RecyclerView-21.0.2. Tested On: Genymotion Nexus 5 Lollipop Preview The Code (Simplified) I have three shared elements: Source: <CardView android:transitionName="cardView"> <ImageView android:transitionName="imageView"> <TextView android:transitionName="textView"> Target: <RelativeLayout

问题 I want to remove the shadow below the ActionBar. I know that I need to change the elevation to 0dp, but I want to do it in the theme. For Android 4.4- I use : <item name="android:windowContentOverlay">@null</item> But is it possible for Android 5.0 ? 回答1: As shown by Antonio Jose, here is an answer : Remove shadow below actionbar For Android 5.0, if you want to set it directly into a style use: <item name="android:elevation">0dp</item> and for Support library compatibility use: <item name=

问题 Background : I use a BLE device (`peer') that communicates with my Android app without pairing -- the peer device advertises and android connects to it. During this connection, the Android device transmits its own Bluetooth address (this is part of each connection). Under Android 4.4 this used to be its public static (i.e. Bluetooth-MAC) address, under Android 5 (at least with my Nexus 9) this is a private random address. The Problem : The peer device checks the supplied address of the
