In the Android development process, the interface layout is important, but it is also complex. Sometimes we rush to actually run to see the layout effect. But I really don't want to puke on Android, especially as the layout gets more complex, projects get bigger and more resources are available.
In particular, the initialization of the Android view, Findviewbyid is completely physical, and we can automatically generate the initialization code for the view based on the layout file.
First declare:
1. This is easy to do and practical, but it works well with complex layouts and first-write initialization view code.
2. Initialization code can only be generated for view with ID tags.
Ideas
In fact, it is very simple to parse the layout layout file, put some information (tag type, id name, etc.) of the label with ID attribute, and then generate the fixed code based on the information.
Realize
Directly on the code, first of all, the layout file parsing, the resolution of the information placed in a list
Copy Code code as follows:
public class Saxhander extends DefaultHandler {
Private list<idnamepair> map = new arraylist<idnamepair> ();
@Override
public void Startdocument () throws Saxexception {
Super.startdocument ();
Map.clear ();
}
@Override
public void Startelement (string uri, String localname, String qName, Attributes Attributes) throws Saxexception {
Super.startelement (URI, LocalName, qName, attributes);
System.out.println ("-------------------------------------");
String tempid = attributes.getvalue ("id");
String id = null;
if (tempid!= null) {
string[] ss = Tempid.split ("/");
if (ss!= null && ss.length = 2) {
id = ss[1];
}
}
if (ID!= null) {
Map.add (new Idnamepair (ID, qName));
}
SYSTEM.OUT.PRINTLN (ID);
System.out.println (QName);
}
Public list<idnamepair> Getres () {
return map;
}
}
Copy Code code as follows:
public class Idnamepair {
Private String ID;
private String name;
/**
* @param ID
* @param name
*/
Public Idnamepair (string ID, string name) {
Super ();
This.id = ID;
THIS.name = name;
}
Public String getId () {
return ID;
}
public void SetId (String id) {
This.id = ID;
}
Public String GetName () {
return name;
}
public void SetName (String name) {
THIS.name = name;
}
}
And then a little bit of stitching code
Copy Code code as follows:
public class Viewcodeutil {
static SAXParserFactory SAXFAC = Saxparserfactory.newinstance ();
static Saxhander Mysax = new Saxhander ();
public static string GetCode (String resfilename) {
File F = new file (resfilename);
if (!f.exists ()) {
return null;
}
try {
Saxfac.newsaxparser (). Parse (F,mysax);
catch (Exception e) {
TODO auto-generated Catch block
E.printstacktrace ();
return null;
}
list<idnamepair> res = Mysax.getres ();
StringBuilder sb = new StringBuilder ();
StringBuilder sb1 = new StringBuilder ();
Sb.append ("//----------start defining domain--------------\ n");
Sb1.append ("//----------start Initview method------------------\ n");
Sb1.append ("public void Initview () {\ n");
for (Idnamepair idnamepair:res) {
Sb.append ("Private" +idnamepair.getname () + "" + Idnamepair.getid () +idnamepair.getname () + "; \ n");
Sb1.append ("" "+idnamepair.getid () +idnamepair.getname () +" = ("+idnamepair.getname () +") Findviewbyid (R.id. ") +idnamepair.getid () + "); \ n");
}
Sb1.append ("}\n");
System.out.println (Sb.tostring ());
System.out.println (Sb1.tostring ());
Return Sb.append (Sb1.tostring ()). ToString ();
}
Finally, the test class Main method.
Copy Code code as follows:
public class Test {
private static final string[] Layoutfiles ={"./res/g_ruler.xml", "./res/report.xml"};
public static void Main (string[] args) {
if (args!=null) {
for (int i = 0; i < args.length; i++) {
System.out.println ("");
System.out.println ("---------" +args[i]+ "----------");
System.out.println (Viewcodeutil.getcode (args[i));
}
}
for (int i = 0; i < layoutfiles.length; i++) {
System.out.println ("");
SYSTEM.OUT.PRINTLN ("//---------" +layoutfiles[i]+ "----------");
System.out.println (Viewcodeutil.getcode (layoutfiles[i));
}
}
}
