android tablayout怎么使用代码切换tab

重新设置点击事件

viewPager.setAdapter(pagerAdapter);

tabLayout.setupWithViewPager(viewPager);

for (int i = 0; i < tabLayout.getTabCount(); i++) {

TabLayout.Tab tab = tabLayout.getTabAt(i);

if (tab != null) {

tab.setCustomView(pagerAdapter.getTabView(i));

if (tab.getCustomView() != null) {

View tabView = (View) tab.getCustomView().getParent();

tabView.setTag(i);

tabView.setOnClickListener(mTabOnClickListener);

}

}

}

viewPager.setCurrentItem(1);

处理点击事件

private View.OnClickListener mTabOnClickListener = new View.OnClickListener() {

@Override

public void onClick(View view) {

int pos = (int) view.getTag();

if (pos == 0) {

Toast.makeText(BottomTabActivity.this, "您还没有登录", Toast.LENGTH_SHORT).show();

//TODO 跳转到登录界面

} else {

TabLayout.Tab tab = tabLayout.getTabAt(pos);

if (tab != null) {

tab.select();

}

}

}

};
