我想将活动标签的文字颜色更改为白色。现在我正在使用选择器,非活动选项卡是灰色的,但活动选项卡不是白色。
XML选择器:
<!-- Tab is active -->
<item android:state_checked="true"
android:color="@color/tab_color_active" />
<!-- Default -->
<item android:color="@color/tab_color_default" />
</selector>
布局部分:
<android.support.v4.view.PagerTabStrip
android:id="@+id/pager_tab_strip"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_gravity="top"
android:background="#3D3D3D"
android:paddingBottom="4dp"
android:paddingTop="4dp"
android:textColor="@drawable/tab_selector" />
这是我片段的相关代码:
@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
View rootView = inflater.inflate(R.layout.fragment_community, container, false);
viewPagerAdapter = new ViewPagerAdapter(getChildFragmentManager());
viewPager = (ViewPager) rootView.findViewById(R.id.pager);
viewPager.setAdapter(viewPagerAdapter);
pagerTabStrip = (PagerTabStrip) rootView.findViewById(R.id.pager_tab_strip);
pagerTabStrip.setDrawFullUnderline(true);
pagerTabStrip.setTabIndicatorColor(Color.WHITE);
return rootView;
}
ViewPagerAdapter:
public class ViewPagerAdapter extends FragmentPagerAdapter {
final int PAGE_COUNT = 4;
private String tabTitles[] = new String[] {"Tab 1", "Tab 2", "Tab 3", "Tab 4"};
public ViewPagerAdapter(FragmentManager fm) {
super(fm);
}
@Override
public Fragment getItem(int position) {
switch(position) {
case 0:
Fragment1 fragment1 = new Fragment1();
return fragment1;
case 1:
Fragment2 fragment2 = new Fragment2();
return fragment2;
case 2:
Fragment3 fragment3 = new Fragment3();
return fragment3;
case 3:
MyImagesFragment fragment4 = new MyImagesFragment();
return fragment4;
}
return null;
}
@Override
public int getCount() {
return PAGE_COUNT;
}
@Override
public CharSequence getPageTitle(int position) {
Locale l = Locale.getDefault();
return tabTitles[position].toUpperCase(l);
}
}
以下是它的样子: http://fs1.directupload.net/images/150409/3msfxnnl.png
我希望Tab 1的文本颜色为白色,因为它是活动的。此外,我希望起始选项卡是选项卡2而不是选项卡1。 有谁知道怎么做?
