我尝试使用 ScrollView 和一个带有 ViewPager 的 LinearLayout，但我只显示了一个 ViewPager.甚至可以在一个屏幕上获得多个 ViewPager 吗?

I tried with ScrollView and a LinearLayout with ViewPagers inside it, but I only get one ViewPager shown. Is it even possible to get several ViewPagers on one screen?

到目前为止我的代码:main.xml

<?xml version="1.0" encoding="utf-8"?>
<ScrollView xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="fill_parent"
    android:layout_height="fill_parent">

    <LinearLayout
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        android:orientation="vertical" >

        <android.support.v4.view.ViewPager
            android:id="@+id/viewpager2"
            android:layout_width="wrap_content"
            android:layout_height="100dp" />

        <android.support.v4.view.ViewPager
            android:id="@+id/viewpager3"
            android:layout_width="wrap_content"
            android:layout_height="100dp" />
    </LinearLayout>

</ScrollView>

MainActivity

public class MainActivity extends Activity{
    @Override
    protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
        setContentView(R.layout.main);
        ViewPagerAdapter adapter2 = new ViewPagerAdapter( this );
        ViewPager pager = (ViewPager)findViewById( R.id.viewpager2 );
        pager.setAdapter( adapter2 );

        ViewPagerAdapter adapter3 = new ViewPagerAdapter( this );
        ViewPager pager3 =
            (ViewPager)findViewById( R.id.viewpager3 );
        pager3.setAdapter( adapter3 );   
    }

}

有什么想法吗?谢谢！这段代码确实有效！

Any ideas? Thanks! this code actually works!

推荐答案

在您的 LinearLayout 上，在您的 XML 中.设置 android:weightSum="2".对于每个 viewpager，设置 android:layout_weight="1".此外，将 LinearLayout 的每个子项的高度设置为 0dp.这应该可以解决问题

On your LinearLayout, in your XML. Set android:weightSum="2". For each viewpager, set android:layout_weight="1". Also, set the height of each child of the LinearLayout to 0dp. That should do the trick
