我试图用TextView的构造与风格是这样的：

I'm trying to use the TextView constructor with style like this:

会将myText的TextView =新的TextView（MyActivity.this，空，R.style.my_style）;

TextView myText = new TextView(MyActivity.this, null, R.style.my_style );

然而，当我做到这一点，文中观点似乎并没有采取风格（我用一个静态对象设置验证它的样式）。

however, when i do this, the text view does not appear to take the style (I verified the style by setting it on a static object).

我也试着使用 myText.setTextAppearance（MyActivity.this，R.style.my_style），但它也不能正常工作

I've also tried using myText.setTextAppearance(MyActivity.this, R.style.my_style) but it also doesn't work

推荐答案

我不相信你可以编程设置样式。为了解决这个问题，你可以创建一个指定的样式模板布局xml文件，例如在RES /布局创建tvtemplate.xml与以下内容：

I do not believe you can set the style programatically. To get around this you can create a template layout xml file with the style assigned, for example in res/layout create tvtemplate.xml as with the following content:

<?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" />

再膨胀这个实例化新的TextView：

then inflate this to instantiate your new TextView:

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

希望这有助于。

Hope this helps.
