我尝试使用此方法为文本视图设置字体:
public static final void setAppFont(ViewGroup mContainer, Typeface mFont)
{
if (mContainer == null || mFont == null) return;
final int mCount = mContainer.getChildCount();
// Loop through all of the children.
for (int i = 0; i < mCount; ++i)
{
final View mChild = mContainer.getChildAt(i);
if (mChild instanceof TextView)
{
// Set the font if it is a TextView.
((TextView) mChild).setTypeface(mFont);
}
else if (mChild instanceof ViewGroup)
{
// Recursively attempt another ViewGroup.
setAppFont((ViewGroup) mChild, mFont);
}
}
