Question

目前，我正在尝试将带图标的SlidingTab实现为tabtitle，然后在选择相应的标签时突出显示图标。

我在以下教程中使用了Google的SlidingTabLayout，并且也制作了图标而不是tabtitle。 https://www.youtube.com/watch?v=WSaSNX5QI-E

我知道在哪里可以通过实现OnPageChangeListener获取当前标签位置，但我不知道应该在public void onPageSelected（int position）{}中添加什么这是我目前的状态和代码，请提供建议，如果您尽可能详细地保留说明，我们将不胜感激，因为我是一名非常初学的Android开发人员。

感谢

    mTabs.setOnPageChangeListener(this);
    mTabs.setCustomTabView(R.layout.custom_tab_view, R.id.tabText);

    mTabs.setCustomTabColorizer(new SlidingTabLayout.TabColorizer() {
        @Override
        public int getIndicatorColor(int position) {
            return getResources().getColor(R.color.tabsScrollColor);
        }
    });

    mTabs.setViewPager(mPager);

}


@Override
public boolean onCreateOptionsMenu(Menu menu) {
    // Inflate the menu; this adds items to the action bar if it is present.
    getMenuInflater().inflate(R.menu.menu_main, menu);
    return true;
}

@Override
public boolean onOptionsItemSelected(MenuItem item) {
    // Handle action bar item clicks here. The action bar will
    // automatically handle clicks on the Home/Up button, so long
    // as you specify a parent activity in AndroidManifest.xml.
    int id = item.getItemId();

    //noinspection SimplifiableIfStatement
    if (id == R.id.action_settings) {
        return true;
    }

    return super.onOptionsItemSelected(item);
}

@Override
public void onPageScrolled(int position, float positionOffset, int positionOffsetPixels) {

}

@Override
public void onPageSelected(int position) {
    Toast.makeText(this, Integer.toString(position), Toast.LENGTH_LONG).show();
}

@Override
public void onPageScrollStateChanged(int state) {

}

}
