Android References external fonts

When doing Android development, some software will require some special fonts, we need to introduce the external TTF format font into the program, the specific steps are:

Create a new fonts directory in the Android app directory assets, copy the TTF font file we need to use (the OTF format directly changes the suffix to TTF), then the code:

//  Save the font file in the assets/fonts/directory,  in   program    Typeface Typeface = Typeface.createfromasset (Getassets (), "Fonts/droidsansthai.ttf"  ); //  textview.settypeface (typeFace); 

Ps:1. If you want to make the font bold again on this basis, use android:textstyle= "bold" in the XML file of the interface configuration is futile, the wood has the effect, at this time how to do?
We can still control in the code, plus a line of code:
Et_note.getpaint (). Setfakeboldtext (true); it can be achieved.

If you want the entire interface to use the same font, you can use batch processing to add a new Java class, as follows:

The code is used to load all TextView-based text components (TextView, buttons, RadioButton, ToggleButton, and so on) without regard to the layout hierarchy of the interface. ( Large memory waste)

In addition TTF font library files are relatively large, will increase the volume of the installation package OH

public class FontManager {            public static void changeFonts(ViewGroup root, Activity act) {               Typeface tf = Typeface.createFromAsset(act.getAssets(),                  "fonts/xxx.ttf" );               for ( int i =  0 ; i < root.getChildCount(); i++) {               View v = root.getChildAt(i);               if (v  instanceof TextView) {                  ((TextView) v).setTypeface(tf);               }  else if (v  instanceof Button) {                  ((Button) v).setTypeface(tf);               }  else if (v  instanceof EditText) {                  ((EditText) v).setTypeface(tf);               }  else if (v  instanceof ViewGroup) {                  changeFonts((ViewGroup) v, act);               }           }            }   }
