Question

我在appcompat v7中有一个工具栏和一个标签布局的应用程序。我使用View Pager浏览标签，但问题是将可扩展列表视图放在哪里，不滚动：这是我的主要活动的Java代码

最小的API是15：Android Ice Cream Sandwicth 4.0.4

public class Principal extends AppCompatActivity{
@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);

    setContentView(R.layout.activity_principal);
    Toolbar toolbar = (Toolbar) findViewById(R.id.toolbar);
    setSupportActionBar(toolbar);

    final TabLayout Tabulacion = (TabLayout) findViewById(R.id.Tabulacion);
    final ViewPager viewPager = (ViewPager) findViewById(R.id.Pager);
    final PagerAdapter adapter = new PagerAdapter(getSupportFragmentManager(), Tabulacion.getTabCount());

    viewPager.setAdapter(adapter);
    viewPager.addOnPageChangeListener(new TabLayout.TabLayoutOnPageChangeListener(Tabulacion));
    Tabulacion.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) {

        }
    });
}

来自PagerAdapter的Java代码

public class PagerAdapter extends FragmentStatePagerAdapter {
int intNumTabs;

public PagerAdapter(FragmentManager FM, int NumTabs) {
    super(FM);
    this.intNumTabs = NumTabs;
}

@Override
public Fragment getItem(int position) {

    switch (position) {
        case 0:
            TabHome Tab1 = new TabHome();
            return Tab1;
        case 1:
            TabLectura Tab2 = new TabLectura();
            return Tab2;
        default:
            return null;
    }
}

@Override
public int getCount() {
    return intNumTabs;
}
}

来自主要活动的XML代码

<android.support.design.widget.CoordinatorLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:fitsSystemWindows="true"
tools:context=".Principal">

<android.support.design.widget.AppBarLayout
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:theme="@style/AppTheme.AppBarOverlay"
    android:id="@+id/textView">

    <android.support.v7.widget.Toolbar
        android:id="@+id/toolbar"
        android:layout_width="match_parent"
        android:layout_height="?attr/actionBarSize"
        android:background="?attr/colorPrimary"
        app:popupTheme="@style/AppTheme.PopupOverlay" />

    <android.support.design.widget.TabLayout
        android:id="@+id/Tabulacion"
        android:layout_width="match_parent"
        android:layout_height="wrap_content">
        <android.support.design.widget.TabItem
            android:layout_width="match_parent"
            android:layout_height="wrap_content"
            android:text="Inicio">
        </android.support.design.widget.TabItem>
        <android.support.design.widget.TabItem
            android:layout_width="match_parent"
            android:layout_height="wrap_content"
            android:text="Lectura">
        </android.support.design.widget.TabItem>
    </android.support.design.widget.TabLayout>
    <android.support.v4.view.ViewPager
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:id="@+id/Pager"
        android:isScrollContainer="true"
        android:nestedScrollingEnabled="true"
        android:background="@color/backgroundColor" />
</android.support.design.widget.AppBarLayout>
</android.support.design.widget.CoordinatorLayout>

标签2片段中的XML代码：

<ExpandableListView xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:id="@+id/ListView">
</ExpandableListView>

可扩展列表视图的内容是动态生成的

我解决了！我从XML中的app coordinator布局中提取视图分页器，有最终代码

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout
xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical"
tools:context=".Principal">
<android.support.design.widget.CoordinatorLayout
    android:layout_width="match_parent"
    android:layout_height="wrap_content">
    <android.support.design.widget.AppBarLayout
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:theme="@style/AppTheme.AppBarOverlay"
        android:id="@+id/textView">

        <android.support.v7.widget.Toolbar
            android:id="@+id/toolbar"
            android:layout_width="match_parent"
            android:layout_height="?attr/actionBarSize"
            android:background="?attr/colorPrimary"
            app:popupTheme="@style/AppTheme.PopupOverlay" />

        <android.support.design.widget.TabLayout
            android:id="@+id/Tabulacion"
            android:layout_width="match_parent"
            android:layout_height="wrap_content">
            <android.support.design.widget.TabItem
                android:layout_width="match_parent"
                android:layout_height="wrap_content"
                android:text="Inicio">
            </android.support.design.widget.TabItem>
            <android.support.design.widget.TabItem
                android:layout_width="match_parent"
                android:layout_height="wrap_content"
                android:text="Lectura">

        </android.support.design.widget.TabLayout>
    </android.support.design.widget.AppBarLayout>
</android.support.design.widget.CoordinatorLayout>

<android.support.v4.view.ViewPager
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:id="@+id/Pager"
    android:background="@color/backgroundColor" />
</LinearLayout>

Answer 2

使用recyclerview而不是listview。我已在视图寻呼机中实现它，它完美地工作。 Recyclerview几乎可以完成listview所做的一切以及更多工作。
