Dynamic skinning from the XML in the SD card get colorstatelist

Colorstatelist value = new Colorstatelist (states, colors);

Seeing Colorstatelist's construction method, we know that to get a colorstatelist, we need to have a

Int[][]

and a storage colorres.

Int[]

First look at a very common selector structure of the Color.xml

<?xml version= "1.0" encoding= "Utf-8"? ><selector    xmlns:android= "http://schemas.android.com/apk/res/ Android ">    <item android:color=" #ffffff "android:state_enabled=" true "android:state_pressed=" true "/>    <item android:color= "#000000"/></selector>

To parse such an XML document, use XML parsing library, I use Jsoup, in Androidstudio gradle add

Compile ' org.jsoup:jsoup:1.8.2 '

You can use this library.

Final file Colordir = new file (skindirectory, "color");//Specify the Color folder under the SD card directory, this directory is passed in by external if (Colordir.exists ())                    {Final file[] files = colordir.listfiles (Mxmlfilter);                        for (file file:files) {final Document parse = jsoup.parse (file, "UTF-8");//parse XML file into Document object                        Final Elements selectors = Parse.getelementsbytag ("selector");//Get selector node list, actually only one selector in the list                        if (Selectors.isempty ()) {continue;                        } final Element selector = selectors.get (0);                        Final Elements children = Selector.children ();                        Int[][] states = new Int[children.size () [];                        int[] colors = new int[children.size ()];                            for (int i = 0; i < children.size (); i++) {Element child = Children.get (i); if ("Item ". Equals (Child.tagname ())) {//Get Item node final Attributes Attributes = Child.attributes ()                                ; The attribute set of the//item node String value = Attributes.get ("Android:color");                                Final int parsecolor = Color.parsecolor (value);                                States[i] = Getstatesarr (attributes);                            Colors[i] = Parsecolor; }} colorstatelist value = new Colorstatelist (states, colors);

The main thing in this code is to take the property of each item, for example, Android:color is a property of item, take the value of color, and convert it to Colorint by Color.parsecolor.

Private int[] Getstatesarr (Attributes Attributes) {list<integer> statelist = new arraylist<> ();        String attributepress = Attributes.get ("android:state_pressed"); if (!            Textutils.isempty (Attributepress)) {Boolean ispressed = Boolean.parseboolean (attributepress); Statelist.add ((ispressed? 1:-1) * Android.        r.attr.state_pressed);        } String Attributefocus = Attributes.get ("android:state_focused"); if (!            Textutils.isempty (Attributefocus)) {Boolean ispressed = Boolean.parseboolean (Attributefocus); Statelist.add ((ispressed? 1:-1) * Android.        r.attr.state_focused);        } String Attributeselect = Attributes.get ("android:state_selected"); if (!            Textutils.isempty (Attributeselect)) {Boolean ispressed = Boolean.parseboolean (Attributeselect); Statelist.add ((ispressed? 1:-1) * Android.        r.attr.state_selected); } String attributeactive = attributes.geT ("android:state_active"); if (!            Textutils.isempty (Attributeactive)) {Boolean ispressed = Boolean.parseboolean (attributeactive); Statelist.add ((ispressed? 1:-1) * Android.        r.attr.state_active);        } String attributecheckable = Attributes.get ("android:state_checkable"); if (!            Textutils.isempty (Attributecheckable)) {Boolean ispressed = Boolean.parseboolean (attributecheckable); Statelist.add ((ispressed? 1:-1) * Android.        r.attr.state_checkable);        } String attributechecked = Attributes.get ("android:state_checked"); if (!            Textutils.isempty (attributechecked)) {Boolean ispressed = Boolean.parseboolean (attributechecked); Statelist.add ((ispressed? 1:-1) * Android.        r.attr.state_checked);        } String attributeenable = Attributes.get ("android:state_enabled"); if (! Textutils.isempty (Attributeenable)) {Boolean ispressed = Boolean.parseboolean (AttributeenabLe); Statelist.add ((ispressed? 1:-1) * Android.        r.attr.state_enabled);        } String Attributewindowfocus = Attributes.get ("android:state_window_focused"); if (!            Textutils.isempty (Attributewindowfocus)) {Boolean ispressed = Boolean.parseboolean (Attributewindowfocus); Statelist.add ((ispressed? 1:-1) * Android.        r.attr.state_window_focused);        } if (Statelist.isempty ()) {return new int[]{};            }else{int[] Statearr =new int[statelist.size ()];            for (int i=0;i<statelist.size (); i++) {statearr[i] =statelist.get (i);        } return Statearr; }    }

This is the int value corresponding to each state, such as android:state_pressed to true, to add Android. R.attr.state_pressed to the array, if False to add-android. r.attr.state_pressed, negative.
