PagerSlidingTabStrip 高亮选中标题

1、选中标题后，高亮标题
@Override
        public void onPageSelected(int position) {
            setSelectTextColor(position);
            if (delegatePageListener != null) {
                delegatePageListener.onPageSelected(position);
            }
        }

private void setSelectTextColor(int position) {
        for (int i = 0; i < tabCount; i++) {
            View view = tabsContainer.getChildAt(i);
            if (view instanceof ImageButton) {
            } else if (view instanceof RelativeLayout) {
                View viewText = ((RelativeLayout) view).getChildAt(0);
                TextView tabTextView = (TextView) viewText;
                if (viewText instanceof TextView) {
                    if (position == i) {
                        tabTextView.setTextColor(自定义颜色);
                    } else {
                        tabTextView.setTextColor(tabTextColor);
                    }
                }
            }
        }
    }

2、首次进入默认第一个标题高亮，关键标红代码

    private void updateTabStyles() {

        for (int i = 0; i < tabCount; i++) {

            View v = tabsContainer.getChildAt(i);

            v.setBackgroundResource(tabBackgroundResId);

            if (v instanceof RelativeLayout) {
                View v1 = ((RelativeLayout) v).getChildAt(0);
                if (v1 instanceof TextView) {

                    TextView tab = (TextView) v1;
                    tab.setTextSize(TypedValue.COMPLEX_UNIT_PX, tabTextSize);
                    tab.setTypeface(tabTypeface, tabTypefaceStyle);
                    if (i == 0) {
                        tab.setTextColor(自定义颜色);
                    } else {
                        tab.setTextColor(tabTextColor);
                    }

                    if (textAllCaps) {
                        if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.ICE_CREAM_SANDWICH) {
                            tab.setAllCaps(true);
                        } else {
                            tab.setText(tab.getText().toString().toUpperCase(locale));
                        }
                    }
                }
            }
        }
    }
