android-xml

问题 Forgive me if this is a simple question however I am new to Android Development and this problem has been bugging me. I have a "base" layout file which contains a RelativeLayout and a com.devspark.sidenavigation.SideNavigationView from this library. I then have an activity with a ViewPager which inflates other layouts (containing ListViews and progressBars) into this. My issue is that however I try and do it, the SideNavigationMenu always appears behind the inflated listviews. I'm not sure

问题 I am working on a project that requires me to implement two horizontal scroll views with an image view in between them. I would like to extend the size of the image view to fill up the gap in between the scroll view. I went through the sample code, but it doesn't seem to mention anywhere in the size of the image view. I've enclosed the code below after the Image describing my problem. public class Gallery2DemoActivity extends Activity { private Gallery gallery,gallery1; private ImageView

问题 I've got an app that pulls XML from the Web, and caches it locally. As parsing XML is expensive compared to parsing Android binary XML, I'd like to store my local copy as Android binary XML. I haven't spotted an API for creating Android binary XML on the fly though, only the C/C++ code used by AAPT. My motivation for taking this approach is that I don't currently use all the XML values/attributes, but may want to use more of them in a future version of my app, and don't want to download all

问题 So my XML goes like this: <?xml version="1.0" encoding="utf-8"?> <android.support.v4.widget.DrawerLayout xmlns:android="http://schemas.android.com/apk/res/android" android:id="@+id/drawer_layout" android:layout_width="match_parent" android:layout_height="match_parent" > <android.support.v7.widget.Toolbar android:id="@+id/my_toolbar" android:layout_height="56dp" android:layout_width="match_parent" android:minHeight="?attr/actionBarSize" android:background="?attr/colorPrimary" /> <FrameLayout

问题 I am trying to create a shape to be used for my imagebuttons in my Android project that would essentially have half circles for the left and right sides. I thought I could just use a shape XML with a radius, but that just rounds the corners where I need the whole left and right sides to be half circles like the image below. My current XML for the shape looks like this: <?xml version="1.0" encoding="utf-8"?> <shape xmlns:android="http://schemas.android.com/apk/res/android" android:shape=

问题 In my xml layouts I have a custom view in which i will put some children like: <com.proj.layouts.components.ScrollLayout android:id="@+id/slBody" android:layout_width="700dp" android:layout_height="400dp"> <TextView android:layout_width="wrap_content" android:layout_height="wrap_content" android:text="child1"/> <TextView android:layout_width="wrap_content" android:layout_height="wrap_content" android:text="child2"/> <TextView android:layout_width="wrap_content" android:layout_height="wrap
