Android Development different font settings

　　Control of different text fonts in development is mainly the use of typeface objects

Because it is a simple demo, are using the Android native components, although ugly, you can learn something is OK! (if there are errors or deficiencies, please enlighten me, thank you!) ）

Let's take a look at the simple running effect.

　　　　　　

　　　　　　　　　

That is, setting two buttons, one TextView, and clicking a different button triggers a different event. Directly on the code

Mainactivity.java

1  Public classMainactivityextendsActivityImplementsOnclicklistener {2 3     PrivateButton changesize;4     PrivateButton Changefont;5     PrivateTextView TV;6 7 @Override8     protected voidonCreate (Bundle savedinstancestate) {9         Super. OnCreate (savedinstancestate);Ten Initview (); One     } A  -     Private voidInitview () { - requestwindowfeature (window.feature_no_title); the Setcontentview (r.layout.activity_main); -TV =(TextView) Findviewbyid (r.id.tv); -Changesize =(Button) Findviewbyid (r.id.changesize); -Changefont =(Button) Findviewbyid (r.id.changefont); +Changesize.setonclicklistener ( This); -Changefont.setonclicklistener ( This); +     } A  at @Override -      Public voidOnClick (View v) { -         Switch(V.getid ()) { -          Caser.id.changesize: -             //use Settextsize to change font size in SP -Tv.settextsize (20); in              Break; -          CaseR.id.changefont: to             //must time under assets create a Fonts folder put in the font file (. ttf) you want to use, providing a relative path to createfromassets () to create the typeface object +Tv.settypeface (Typeface.createfromasset (Getassets (), "Fonts/song.ttf")); -         default: the              Break; *         } $     }Panax Notoginseng}

Activity_main.xml

1<relativelayout xmlns:android= "Http://schemas.android.com/apk/res/android"2Xmlns:tools= "Http://schemas.android.com/tools"3Android:layout_width= "Match_parent"4android:layout_height= "Match_parent"5Tools:context= ".

By placing the external font file under fonts/, you can use Assetsmanage to reference external resources

In addition to the use of Createfromasset to construct typeface, but also through the Defaultfromstyle to use the Android built-in several typeface, here no longer repeat, the following is the type of typeface hierarchy, You can see a few common methods.
