我有ViewPager,在它下面我有10个按钮.通过单击按钮,例如#4,寻呼机立即转到第4页mPager.setCurrentItem(3);.但是,我想通过水平手指滑动来禁用分页.因此,寻呼完成仅通过点击按钮.那么,我怎么能用手指禁用滑动？
我想TabLayout在我的应用程序中使用fragment和ViewPager.
但我希望禁用点击TabLayout以在其间切换fragment,只需滑动即可切换fragmenst.
我写下面的代码,但没有工作,当点击TabLayout项目时,去那fragment!

我需要为我正在开发的应用程序选项卡.所以我最终得到了tablayout,它包含很少的标签.代码如下:
private void setupNavTab() {

new int[]{android.R.attr.state_selected},
new int[]{-android.R.attr.state_selected},
new int[]{-android.R.attr.state_enabled}
};

ContextCompat.getColor(getActivity(), R.color.nav_bar_unselected_content),
ContextCompat.getColor(getActivity(), R.color.edit_button_text_color_inactive)
};
ColorStateList cslist = new ColorStateList(states, colors);
if (tabs != null) {
tabs.removeAllTabs();
tabs.setTabTextColors(cslist);
firstTab = tabs.newTab().setTag(TAB_FIRST);
View customFirstTabView = LayoutInflater.from(getActivity()).inflate(R.layout.tab_item_layout, null, false);
firstTabView = (TextView) customFirstTabView.findViewById(R.id.textContainer);
firstTabView.setText(R.string.first);
firstTabView.setTextColor(cslist);
firstTab.setCustomView(customFirstTabView);
secondTab = tabs.newTab().setTag(TAB_SECOND);
View customSecondView = LayoutInflater.from(getActivity()).inflate(R.layout.tab_item_layout, null, false);
secondTabView = (TextView) customSecondView.findViewById(R.id.textContainer);
secondTabView.setText(R.string.second);
secondTabView.setTextColor(cslist);
secondTab.setCustomView(customSecondView);
thirdTab = tabs.newTab().setTag(TAB_THIRD);
View customThirdTabView
= …我使用控件 android.support.design.widget.TabLayout
我有 4 个选项卡 - 在每个选项卡上我显示一些 ViewPager -（使用片段来显示不同的 viewPager）
我想禁用所有选项卡，直到用户添加一些存在于第一个选项卡上的数据。
我没有找到禁用选项卡的任何方法。
