Android - 以编程方式设置 TextView TextStyle?

2022-01-09 00:00:00 android java textview

有没有办法以编程方式设置 TextView 的 textStyle 属性?似乎没有 setTextStyle() 方法.

Is there a way to set the textStyle attribute of a TextView programmatically? There doesn't appear to be a setTextStyle() method.

要清楚，我不是在谈论 View/Widget 样式！我说的是以下内容:

To be clear, I am not talking about View / Widget styles! I am talking about the following:

<TextView
  android:id="@+id/my_text"
  android:layout_width="fill_parent"
  android:layout_height="wrap_content"
  android:text="Hello World"
  android:textStyle="bold" />

推荐答案

textview.setTypeface(Typeface.DEFAULT_BOLD);

setTypeface 是属性 textStyle.

setTypeface is the Attribute textStyle.

正如 Shankar V 添加的那样，为了保留之前设置的字体属性，您可以使用:

As Shankar V added, to preserve the previously set typeface attributes you can use:

textview.setTypeface(textview.getTypeface(), Typeface.BOLD);
