[英]On tab selection change other tabs icons and change the color of the tab text programmatically in android
我已经为每个选项卡开发了具有自定义布局的tabbedview。现在,当我选择一个选项卡时,其他选项卡的图标应该更改,并且我想更改其他选项卡文本的颜色。 请帮忙?
这是我的代码:
final TabLayout tabLayout = (TabLayout) findViewById(R.id.tab_layout);
tabLayout.addTab(tabLayout.newTab().setCustomView(R.layout.custom_tab_one));
tabLayout.addTab(tabLayout.newTab().setCustomView(R.layout.custom_tab_two));
tabLayout.addTab(tabLayout.newTab().setCustomView(R.layout.custom_tab_three));
tabLayout.addTab(tabLayout.newTab().setCustomView(R.layout.custom_tab_four));
final ViewPager viewPager = (ViewPager) findViewById(R.id.pager);
final TabViewAdapter adapter = new TabViewAdapter(getSupportFragmentManager(),tabLayout.getTabCount());
viewPager.setAdapter(adapter);
viewPager.addOnPageChangeListener(new TabLayout.TabLayoutOnPageChangeListener(tabLayout));
tabLayout.setOnTabSelectedListener(new TabLayout.OnTabSelectedListener() {
@Override
public void onTabSelected(TabLayout.Tab tab) {
viewPager.setCurrentItem(tab.getPosition());
}
@Override
public void onTabUnselected(TabLayout.Tab tab) {
}
@Override
public void onTabReselected(TabLayout.Tab tab) {
}
});
}
// - set a tab listener to your tabLayout
tabLayout.setOnTabSelectedListener(new TabLayout.ViewPagerOnTabSelectedListener(viewPager) {
@Override
public void onTabUnselected(TabLayout.Tab tab) {
super.onTabUnselected(tab);
}
// - this method will get execute if you select some tab
@Override
public void onTabSelected(TabLayout.Tab tab) {
super.onTabSelected(tab);
// - here change the color or image of your tab which is selected and of unselected also
}
}
尝试使用此tabSelectedTextColor =“ yourColor”,但是您在Value-> style上拥有样式
<android.support.design.widget.TabLayout
android:id="@+id/tabs"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:background="@color/white"
app:tabMode="scrollable"
app:tabGravity="fill"
app:tabSelectedTextColor="@color/black"
app:tabTextColor="@color/red" />

只需阅读本文,并了解如何更改“标签”图标和颜色。 要在View Pager项上进行更改,可以在View pager中设置PageChangeListener
并根据新页面更新选项卡。 如有任何疑问,请随时发表评论。
