android - 如何以编程方式在所有按钮上应用主题？

Question

这是我的按钮:

public class ChimmerButton extends Button {

public ChimmerButton(Context context) {
    super(context);
}

public ChimmerButton(Context context, AttributeSet attrs) {
    super(context, attrs);
}

public ChimmerButton(Context context, AttributeSet attrs, int defStyle) {
    super(context, attrs, defStyle);
}

/*
 * This method is used to apply the external font
 */
public void setTypeface(Typeface tf, int style) {
    if (!isInEditMode()) {
        super.setTypeface(Typeface.createFromAsset(
                getContext().getAssets(), "calibre-regular.ttf"));
    }
}
}

如何使用以上代码在所有 chimmerButton 上应用 Theme.Light.NoTitleBar.Fullscreen？有解决办法吗？

Answer 1

Note that this should be called before any views are instantiated in the Context (for example before calling setContentView(View) or inflate(int, ViewGroup)).

不幸的是，您必须在显示 Activity 之前设置主题。

因此您不能拥有由运行时代码驱动的“动态”主题(尽管上面的评论显示了如何为您的按钮制作自定义主题)
