如何更改Tablayout字体大小

Question

如何更改android.support.design.widget.TabLayout的字体类型？

我对此问题使用样式，但应用程序在API 16中崩溃。 谢谢。

Answer 1

我发现这种方式：

private void changeTabsFont() { 

     ViewGroup vg = (ViewGroup) tabLayout.getChildAt(0); 
     int tabsCount = vg.getChildCount(); 
     for (int j = 0; j < tabsCount; j++) { 
      ViewGroup vgTab = (ViewGroup) vg.getChildAt(j); 
      int tabChildsCount = vgTab.getChildCount(); 
      for (int i = 0; i < tabChildsCount; i++) { 
       View tabViewChild = vgTab.getChildAt(i); 
       if (tabViewChild instanceof TextView) { 
        ((TextView) tabViewChild).setTypeface(Font.getInstance().getTypeFace(), Typeface.NORMAL); 
       } 
      } 
     } 
    }

试试这个代码：

private void changeTabsFont(TabLayout tabLayout) { 

    ViewGroup vg = (ViewGroup) tabLayout.getChildAt(0); 
    int tabsCount = vg.getChildCount(); 
    for (int j = 0; j < tabsCount; j++) { 
     ViewGroup vgTab = (ViewGroup) vg.getChildAt(j); 
     int tabChildsCount = vgTab.getChildCount(); 
     for (int i = 0; i < tabChildsCount; i++) { 
      View tabViewChild = vgTab.getChildAt(i); 
      if (tabViewChild instanceof TextView) { 
       ((TextView) tabViewChild).setTypeface(/* your typeface */); 
      } 
     } 
    } 
}
