自定义TabLayout Android错误时添加选项卡mTabs

Question

我让我的自定义Tablayout视图自定义Tablayout android的字体，但它给我崩溃mTabs.add（位置，选项卡）;我的代码有什么问题？

@Override 
public void addTab(@NonNull Tab tab, int position, boolean setSelected) { 
    MyTextView myTextView = (MyTextView) 
    View.inflate(getContext(), R.layout.tab_item_template, null); 
    myTextView.setText(tab.getText()); 
    tab.setCustomView(myTextView); 

    mTabs.add(position, tab); 
    super.addTab(tab, position, setSelected); 
} 

误差

java.lang.IndexOutOfBoundsException: Invalid index 10, size is 0 

Answer 1

试试这个设置自定义选项卡中的标签布局

TextView tabOne = (TextView) LayoutInflater.from(this).inflate(R.layout.custom_tab, null); 
tabOne.setText("ONE"); 
tabOne.setTextColor(ContextCompat.getColor(this,R.color.colorAccent)); 
tabOne.setCompoundDrawablesWithIntrinsicBounds(0, R.drawable.ic_tab_favourite, 0, 0);// if you want to set icon on that tab 
tabLayout.getTabAt(0).setCustomView(tabOne);
