您好我必须在我的应用中实施ViewPager
。在这里我必须加载ImageAdapter
扩展PagerAdapter
,我成功地将所有图像都看到了viewpager。
现在,我想将viewpager标题显示为我的图像计数器。
Layout.xml
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:id="@+id/gallery_detail_layout"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:background="@color/black" >
<android.support.v4.view.ViewPager
android:id="@+id/view_pager"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:layout_below="@+id/rel_ig" >
</android.support.v4.view.ViewPager>
</RelativeLayout>
请有人告诉我我想怎么做!

首先需要将android.support.v4.view.PagerTabStrip
添加到Layout.xml
文件中,如:
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:id="@+id/gallery_detail_layout"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:background="@color/black" >
<android.support.v4.view.ViewPager
android:id="@+id/view_pager"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:layout_below="@+id/rel_ig" >
<android.support.v4.view.PagerTabStrip
android:id="@+id/pts_main"
android:layout_width="match_parent"
android:layout_height="wrap_content" />
</android.support.v4.view.ViewPager>
</RelativeLayout>
现在,覆盖CharSequence getPageTitle(int position)
方法int Adapter
,如:
public class ImageAdapter extends PagerAdapter {
............
@Override
public CharSequence getPageTitle(int position) {
return (position + 1);
}
...........
}
并在您的PagerTabStrip
中实施:您可以自定义PagerTabStrip
选项
PagerTabStrip strip = (PagerTabStrip)view.findViewById(R.id.pts_main);
strip.setDrawFullUnderline(false);
strip.setTabIndicatorColor(Color.DKGRAY);
strip.setBackgroundColor(Color.GRAY);
strip.setNonPrimaryAlpha(0.5f);
strip.setTextSpacing(25);
strip.setTextSize(TypedValue.COMPLEX_UNIT_DIP, 16);

试试这个: -
在 activity_main.xml 中添加 PagerTitleStrip :
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:orientation="vertical" >
<android.support.v4.view.ViewPager
android:id="@+android:id/viewpager"
android:layout_width="fill_parent"
android:layout_height="fill_parent" >
<android.support.v4.view.PagerTitleStrip
android:id="@+id/pgrStrp"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_gravity="top" />
</android.support.v4.view.ViewPager>
</LinearLayout>
然后在 PageAdapter.java 中添加以下方法:
@Override
public CharSequence getPageTitle(int position) {
return "Title Here";
}
