android-layout

问题 I'm on a Lollipop device (MotoG 2014), I read about progress bar tinting, but this is not working...I get the default progress bar color. What am I missing here? <ProgressBar style="?android:attr/progressBarStyleLarge" android:layout_width="50dp" android:layout_height="50dp" android:backgroundTintMode="src_in" android:indeterminate="true" android:indeterminateTint="#f00" /> Many thanks. 回答1: The accepted solution wasn't working for me on pre-Lollipop, but I found this solution to fit all APIs

问题 I have a RecyclerView for displaying a list of items. There is this android CardView class given by android to show card layout. If I use a RelativeLayout and set its background to white it works the same way. Also in case of CardView I have to anyway add a childlayout to it which basically contains the all the views inside the card. So I wanted to know if their is any benefit of using a CardView (which actually increases the hierarchy of the views) rather than a normal Layout directly. 回答1:

问题 I have an activity loaded from XML, with views having IDs as usual: <?xml version="1.0" encoding="utf-8"?> <FrameLayout xmlns:android="http://schemas.android.com/apk/res/android" android:layout_width="80dp" android:layout_height="110dp"> <LinearLayout android:layout_width="match_parent" android:layout_height="match_parent" android:orientation="vertical"> <FrameLayout android:layout_width="70dp" android:layout_height="70dp" android:layout_gravity="center_horizontal" android:background="

问题 I have a toolbar like component implementation, that I'm having trouble with the layout in all situations. It has a left icon, a title and a right menu/button. I need the title to be centered on the full screen (or at least the full width of the layout) but also to not overlap with the other components. So the width of the title would have to be constrained by the left icon and the right button. I have two intermediary solutions but can't seem to find a way to combine them. One is to center

问题 I have a question about how to improve the performance of a large horizontal linear layout. I am creating a table like view that can have anywhere from 50 to 2,500 entries. Each entry is a LinearLayout containing a TextView with some simple text. I have implemented the design by utilizing the LinearListView library. This library allows an ListAdapter to be bound to a LinearLayout to display a view in a horizontal or vertical orientation. The way I have implemented this currently is by
