将选项卡添加到 mTab​​ 时自定义 TabLayout android 错误

Question

我制作了自定义 tablayout 视图来自定义 tablayout android 的字体，但它让我在 mTab​​s.add(position, tab); 上崩溃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);
}

错误是

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

Answer 1

尝试在您的标签布局中设置自定义标签

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);
