关于android 动态设置view 样式 问题(默认style)

Button btn=new Button(new ContextThemeWrapper(mContext,R.style.service_text_dialog_style),null,R.style.service_text_dialog_style);

<?xml version="1.0" encoding="utf-8"?>
<TextView xmlns:android="http://schemas.android.com/apk/res/android"
        android:layout_width="fill_parent"
        android:layout_height="wrap_content"
        android:text="This is a template"
        style="@style/my_style" />

TextView myText = (TextView)getLayoutInflater().inflate(R.layout.tvtemplate, null);
