Android automatically matches email addresses, URLs, and phone numbers.

Looking at the android API, you have no intention of seeing linkify. According to API instructions, linkify can convert words that match the rules into clickable connections.

I think this is a little useful. Let's try it.

1. Create a project

2. Modify the Style File

Add an edittext and a textview to view the effect.

CodeAs follows:

<? XML version = "1.0" encoding = "UTF-8"?> <Linearlayout xmlns: Android = "http://schemas.android.com/apk/res/android" Android: Orientation = "vertical" Android: layout_width = "fill_parent" Android: layout_height = "fill_parent" Android: weightsum = "1"> <edittext Android: layout_height = "wrap_content" Android: layout_width = "fill_parent" Android: id = "@ + ID/inputtext"> <requestfocus> </edittext> <textview Android: layout_height = "wrap_content" Droid: textappearance = "? Android: ATTR/textappearancelarge "Android: layout_width =" fill_parent "Android: layout_weight =" 0.08 "Android: Id =" @ + ID/viewtext "Android: TEXT = "Enter the content"> </textview> </linearlayout>
 

3. Modify androidlearnactivity. Java

Let's take a look at the key parts.

In this example, we use the first one. Let's take a look at what linkify supports by default.

Map_addresses I do not understand...

The complete code is as follows:

 Package CN. ghy. sdx;

 Import Android. App. activity;
 Import Android. OS. Bundle;
 Import Android. Text. util. linkify;
 Import Android. View. keyevent;
 Import Android. View. view;
 Import Android. View. View. onkeylistener;
 Import Android. widget. edittext;
Import Android. widget. textview;

 Public   Class Androidlearnactivity Extends Activity {
Edittext;
Textview;
@ Override
 Public   Void Oncreate (bundle savedinstancestate ){
 Super . Oncreate (savedinstancestate );
Setcontentview (R. layout. Main );
Edittext = (edittext)This . Findviewbyid (R. Id. inputtext );
Textview = (textview) This . Findviewbyid (R. Id. viewtext );
Edittext. setonkeylistener ( New Onkeylistener (){

@ Override
 Public   Boolean Onkey (view V, Int Keycode, keyevent event ){
Textview. settext (edittext. gettext ());
Linkify. addlinks (textview, linkify. email_addresses | linkify. phone_numbers | linkify. web_urls );
Return   False ;
}
});
}
}

 

Effect:

URL:

Tel:

Email:

Advanced learning:

The Several built-in functions of linkify can meet the needs, but sometimes they have more flexible needs. For example, you need to enter an ID card number.

I am not very clear about regular expressions. It is easy to use.

 
Textview. settext (edittext. gettext ());
Pattern pattern = pattern. Compile ("\ D {15} | \ D {18 }");
String scheme = "http: // chaxun? Sfz = ";//This is free to write.
Linkify. addlinks (textview, pattern, scheme );
