我在删除标签 com.viewpagerindicator.TabPageIndicator 方面遇到了问题我在很多方面尝试过，但是没有用。
这是我的代码：
<LinearLayout
xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="vertical"
android:layout_width="fill_parent"
android:layout_height="fill_parent">
<com.viewpagerindicator.TabPageIndicator
android:id="@+id/indicator"
android:layout_height="wrap_content"
android:layout_width="fill_parent"
/>
<android.support.v4.view.ViewPager
android:id="@+id/pager"
android:layout_width="fill_parent"
android:layout_height="0dp"
android:layout_weight="1"
/>
</LinearLayout>
这是我的java代码：

这是解决方案：
删除标签的功能：
public void RemoveTab(Integer position) {
CONTENT.remove(position);
ICONS.remove(position);
adapter = new GoogleMusicAdapter(getSupportFragmentManager());
pager.setAdapter(adapter);
indicator = (TabPageIndicator) findViewById(R.id.indicator);
indicator.setViewPager(pager);
indicator.notifyDataSetChanged();
adapter.notifyDataSetChanged();
}
和@Override getItem功能：
@Override
public Fragment getItem(int position) {
if (CONTENT.get(position).equals("Connection")) {
MainFragment f = new MainFragment();
return f;
} else {
if (CONTENT.get(position).equals("Facebook")) {
FacebookNews fb_news = new FacebookNews();
return fb_news;
}
}
return haris.dautovic.main.BaseFragment.newInstance(CONTENT.get(position), position);
}

试用以下XML
<LinearLayout
xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="vertical"
android:layout_width="fill_parent"
android:layout_height="fill_parent">
<com.viewpagerindicator.TabPageIndicator
android:id="@+id/indicator"
android:layout_height="0dp"
android:layout_width="fill_parent"
android:visibility="gone" />
<android.support.v4.view.ViewPager
android:id="@+id/pager"
android:layout_width="fill_parent"
android:layout_height="0dp"
android:layout_weight="1"
/>
</LinearLayout>
