java - ListView不显示所有项目

Question

这个问题看起来很简单，但我现在无法解决这个问题。

我在 ScrollView 中有 ListView (我知道不要这样做)

现在，通过 ScrollView 中的 ListView，我使用自定义 View ExpandableHeightListView ( how to make multiplelistview in Scrollview? ) 来显示所有项目。

这是我的 ScrollView

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

这是listView的项目

<?xml version="1.0" encoding="utf-8"?>

    android:layout_height="wrap_content"
    android:id="@+id/layoutLeft" android:orientation="horizontal">
    <ImageView
        android:layout_width="100dp"
        android:layout_height="100dp"
        android:paddingTop="10dp"
        android:src="@mipmap/ic_launcher"
        android:id="@+id/imageAbility"/>

    <LinearLayout
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:paddingTop="5dp"
        android:orientation="vertical">

        <TextView

            android:id="@+id/txtAbility"
            android:textSize="18sp"
            />

        <TextView
            android:layout_width="match_parent"
            android:layout_height="wrap_content"
            android:textSize="14sp"
            android:id="@+id/txtDetail"
            android:text="akjdfhakdfjhakdfjhadfkjhadkfjakdjfhadksjfhdakfjhadkfadfkjhadklfhafkldahfkasfh"/>


    </LinearLayout>
</LinearLayout>




<LinearLayout
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:orientation="vertical"
    android:paddingLeft="10dp"
    >

    <TextView
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:text="NOTE: blah blahsalkfdjdlkj"
        android:id="@+id/txtAbilityNote"/>

    <TextView
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:id="@+id/txtAffect"
        android:text="A modified technique of the Turstarkuri monks"/>

    <TextView
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:id="@+id/txtAttribs"
        android:text="A modified technique of the Turstarkuri monks"/>
    <TextView
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:id="@+id/txtDamage"
        android:text="A modified technique of the Turstarkuri monks"/>
    <TextView
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:id="@+id/txtCmb"
        android:text="A modified technique of the Turstarkuri monks"/>

</LinearLayout>

这是自定义类实现ListView

 public class ExpandableHeightListView extends ListView{

    boolean expanded = false;

    public ExpandableHeightListView(Context context)
    {
        super(context);
    }

    public ExpandableHeightListView(Context context, AttributeSet attrs)
    {
        super(context, attrs);
    }

    public ExpandableHeightListView(Context context, AttributeSet attrs,int defStyle)
    {
        super(context, attrs, defStyle);
    }

    public boolean isExpanded()
    {
        return expanded;
    }

    @Override
    public void onMeasure(int widthMeasureSpec, int heightMeasureSpec)
    {
        // HACK! TAKE THAT ANDROID!
        if (isExpanded())
        {
            // Calculate entire height by providing a very large height hint.
            // But do not use the highest 2 bits of this integer; those are
            // reserved for the MeasureSpec mode.
            int expandSpec = MeasureSpec.makeMeasureSpec(Integer.MAX_VALUE >> 2, MeasureSpec.AT_MOST);
            super.onMeasure(widthMeasureSpec, expandSpec);

            ViewGroup.LayoutParams params = getLayoutParams();
            params.height = getMeasuredHeight();
        }
        else
        {
            super.onMeasure(widthMeasureSpec, heightMeasureSpec);
        }
    }

    public void setExpanded(boolean expanded)
    {
        this.expanded = expanded;
    }
}

现在，当我通过Adapter将数据设置到ListView时。 ListView 不显示我设置的所有项目。例如:我设置了4个项目，它只显示3或3.5个项目

谁能给我一些建议？

谢谢。

您需要创建一个java自定义ScrollView类并在您的xml中使用它而不是原始的ScrollView。您可以在此处找到 VerticalScrollview 类代码: https://stackoverflow.com/a/13796159/3376613
