Android If overridden OnDraw implements a control similar to the TextView can display emoticons and links (i)

Look first:

Write a hyperlink-supported object:

/** objects displayed as hyperlinks */public class LinkInfo implements comparable<linkinfo>{    private String content;    Private String type;    Private String ID;    Private Boolean bisface = false;    Private Boolean bselected = false;    public static final String email = "email";    public static final String WEBURL = "WEBURL";    public static final String PhoneNumber = "PhoneNumber";    private int startIndex;    private int endIndex;}

This parsing is done for the following string:

String s = "(#大笑)%$%$%3434343434343$%$%[email protected] $dfsfsfsdffds ^15959224872) [Email protected]&& Fefrewafrewfjwio ([email protected] () () [email protected] ";

private static Pattern Email_pattern = patterns.email_address;private static pattern Phone_pattern = Patterns.phone; private static Pattern Weburl_pattern = Patterns.web_url;public static arraylist<linkinfo> parsestr (String    Strlink) {if (Textutils.isempty (Strlink)) {return null;    }arraylist<linkinfo> resultlist = new arraylist<linkinfo> ();    Arraylist<linkinfo> infolist = null;    try{infolist = new arraylist<linkinfo> (); <span style= "White-space:pre" ></span><strong>matcher Matcher = Email_pattern.matcher (StrLink);    Find the location of the email in the string </strong> int begin = 0;    while (Matcher.find ()) {int start = Matcher.start ();        int end = Matcher.end ();        LinkInfo info = new LinkInfo ();        Info.setstartindex (start);            Info.setendindex (end);            Info.setcontent (Matcher.group ());        Info.settype (Linkinfo.email);    Infolist.add (info); } <strong>matcher Matcher1 = Phone_pattern.matcher(strlink);//Find the position of the number in the string </strong> while (Matcher1.find ()) {int start = Matcher1.start ();        int end = Matcher1.end ();        LinkInfo info = new LinkInfo ();        Info.setstartindex (start);            Info.setendindex (end);            Info.setcontent (Matcher1.group ());        Info.settype (Linkinfo.phonenumber);    Infolist.add (info);        }//(#大笑) pattern pattern = pattern.compile ("(\ \ (#\\s{1,2}\\))");     Matcher matcher2 = Pattern.matcher (strlink);    while (Matcher2.find ()) {int start = Matcher2.start ();    int end = Matcher2.end ();        System.out.println ("====start=" +start+ "end=" +end+ "Match group=" +matcher2.group ());        LinkInfo info = new LinkInfo ();        Info.setstartindex (start);            Info.setendindex (end);            Info.setcontent (Matcher2.group ());        Info.setface (TRUE);    Infolist.add (info);    } collections.sort (Infolist);    int last = 0; for (int i=0;i<infolist.size (); i++) {LinkInfo info = infolist.get (i);        if (Begin! = Info.getstartindex ()) {LinkInfo Infobefore = new LinkInfo ();        Infobefore.setcontent (Strlink.substring (Begin,info.getstartindex ()));    Resultlist.add (Infobefore);    } resultlist.add (info);    Begin = Info.getendindex ();    Last = Info.getendindex ();        } if (last < Strlink.length ()) {LinkInfo info = new LinkInfo ();        Info.setcontent (Strlink.substring (Last,strlink.length ()));    Resultlist.add (info);    }}catch (Exception ex) {ex.printstacktrace (); } return resultlist;}

Layout of activity:

<?xml version= "1.0" encoding= "Utf-8"? ><relativelayout xmlns:android= "http://schemas.android.com/apk/res/ Android "Android:layout_width=" Wrap_content "android:layout_height=" wrap_content "android:background=" @drawable/w Hite "> <include android:layout_width=" wrap_content "android:layout_height=" Wrap_content "an Droid:layout_alignparentbottom= "true" android:id= "@+id/header" layout= "@layout/news_header"/> &lt ; Relativelayout android:id= "@+id/title" android:layout_above= "@id/header" android:layout_width= "Fill_ Parent "android:layout_height=" match_parent "android:background=" @drawable/white "android:gravity=" ce Nter_horizontal "> <com.kaixin001.view.introview android:id=" @+id/news_item_text "Andro Id:layout_width= "Fill_parent" android:layout_height= "wrap_content" android:layout_alignparenttop= "tr UE "Android:layout_marginleft= "30DP" android:layout_marginright= "30DP" android:layout_margintop= "20DP" Android : Enabled= "true" android:textcolor= "@drawable/black" android:textsize= "16SP" android:texts tyle= "Bold"/> </RelativeLayout></RelativeLayout>

Introview has such a method to load the string:

<pre name= "code" class= "Java" >public class Introview extends TextView {private arraylist<linkinfo> titlelist;private int displaywidth = 0;private float displayheight = 0;private float Curlen = 0;private Bitmap starBmp;pri vate Bitmap selectedbmp;private Float PosX = 0;private float PosY = 0;private linkinfo curinfo;//current clicked link object private Onclic Klinklistener listener;private String mfacetype = msg_face_type;public static final String Msg_face_type = "Msgtype";p UBL IC static final String Status_face_type = "Statustype";p ublic Introview (context context) {super (context);} Public Introview (context context, AttributeSet Attrs) {Super (context, attrs);} Public Introview (context context, AttributeSet attrs, int defstyle) {Super (context, attrs, Defstyle);}        public void Settitlelist (arraylist<linkinfo> titlelist) {this.titlelist = Titlelist;displayheight = 0; Requestlayout ();}} <span style= "font-family:arial, Helvetica, Sans-serif;" >  &Lt;/span> 

<span style= "font-family:arial, Helvetica, Sans-serif;" ></span>

<span style= "font-family:arial, Helvetica, Sans-serif;" >activity in this way to call:</span>

<span style= "font-family:arial, Helvetica, Sans-serif;" ></span>

Introview News_item_text = (introview) Findviewbyid (R.id.news_item_text);
not supported in string \ n

News_item_text.settitlelist (Parsenewsinfoutil.parsestr (s));
News_item_text.setonclicklinklistener (this);

<span style= "font-family:arial, Helvetica, Sans-serif;" >introview's main idea is to get arraylist<linkinfo> titlelist location information for each LinkInfo in Onmeasure measurewidth and Measureheight. and get the height and width of this introview,</span>

And then ondraw the loop to draw each linkinfo of the titlelist.
