首先在自定义的BaseApplication中设置如下代码：
public class BaseApplication extends Application {
@Override
public void onCreate() {
Typeface typeFaceYaHei = Typeface.createFromAsset(getAssets(),
"fonts/test.ttf");
try {
Field field = Typeface.class.getDeclaredField("SERIF");
field.setAccessible(true);
field.set(null, typeFaceYaHei);
} catch (NoSuchFieldException e) {
e.printStackTrace();
} catch (IllegalAccessException e) {
e.printStackTrace();
}
super.onCreate();
}
}
然后在AndroidManifest.xml中application标签中的theme属性：style对应中添加该行
<item name="android:typeface">serif</item>
但该方法，不能改变Toast中的文字 样式 ，要改变文字样式，需要在toast实例时，自定义view的属性
private voidshowToast(String info) {
if(toast==null) {
toast= Toast.makeText(getApplicationContext(), info, Toast.LENGTH_SHORT);
LinearLayout layout = (LinearLayout)toast.getView();
layout.setBackgroundColor(Color.parseColor("#FFFFFF"));
TextView v = (TextView)toast.getView().findViewById(android.R.id.message);
v.setTextColor(Color.BLACK);
Typeface typeFaceYaHei = Typeface.createFromAsset(getAssets(),
"fonts/Adobe_Heiti_Std_R.TTF");
v.setTypeface(typeFaceYaHei);
v.setTextSize(25);
}else{
toast.setText(info);
}
toast.show();
}
