禁用TabLayout中的选项卡

Question

我TabLayout在我的应用程序中使用了最新的设计支持库.选项卡附加到viewpager,后者为每个选项卡加载片段.我想禁用所有选项卡,直到viewpager为用户选择的选项卡加载片段.我无法禁用tablayout或使其无法点击.我曾经使用过setEnabled(false),setClickable(false)但它没有用.我可以通过使用使其隐藏,setVisiblity(View.GONE)但我希望标签始终可见.

    tabLayout = (TabLayout) findViewById(R.id.tabLayout);
    tabLayout.setTabGravity(TabLayout.GRAVITY_FILL);
    tabLayout.setTabMode(TabLayout.MODE_FIXED);
    tabLayout.addTab(tabLayout.newTab().setIcon(R.drawable.near_me_hover).setTag(1));
    tabLayout.addTab(tabLayout.newTab().setIcon(R.drawable.all_hostels).setTag(2));
    tabLayout.addTab(tabLayout.newTab().setIcon(R.drawable.top_five).setTag(3));
    tabLayout.addTab(tabLayout.newTab().setIcon(R.drawable.advanced_search).setTag(4));
    tabLayout.setEnabled(false);
    tabLayout.setClickable(false);

选项卡单击侦听器实现了 3 个方法，其中之一是onTabSelected() 放置一个布尔条件来检查您的片段是否已初始化。然后，如果满足该条件，则允许交易发生。还在片段代码之后初始化选项卡
