060-Android中ListView嵌套ScrollView

 

 

 

Android中ListView嵌套ScrollView

這種情況下

ListView和其他的佈局是平級的關係

都在ScrollView的佈局之下

實現了滾動佈局和列表

 

 

我們可以寫一個SolidListView 繼承 ListView

 

public class SolidListView extends ListView {

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

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

    public SolidListView(Context context, AttributeSet attrs, int defStyleAttr) {
        super(context, attrs, defStyleAttr);
    }

    @Override
    protected void onMeasure(int widthMeasureSpec, int heightMeasureSpec) {
        int expandSpec = MeasureSpec.makeMeasureSpec(Integer.MAX_VALUE >> 2, MeasureSpec.AT_MOST);
        super.onMeasure(widthMeasureSpec, expandSpec);
    }
}

 

 

 

如果是GridView嵌套ScrollView

也是一樣的道理

 

public class SolidGridView extends GridView {
    public SolidGridView(Context context) {
        super(context);
    }

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

    public SolidGridView(Context context, AttributeSet attrs, int defStyleAttr) {
        super(context, attrs, defStyleAttr);
    }

    @Override
    protected void onMeasure(int widthMeasureSpec, int heightMeasureSpec) {
        int expandSpec = MeasureSpec.makeMeasureSpec(Integer.MAX_VALUE >> 2, MeasureSpec.AT_MOST);
        super.onMeasure(widthMeasureSpec, expandSpec);
    }
}

 

 

 

在佈局中,直接使用SolidListView和SolidGridView

 

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

        <com.lich.view.SolidListView
            android:layout_width="match_parent"
            android:layout_height="wrap_content" />

        <com.lich.view.SolidGridView
            android:layout_width="match_parent"
            android:layout_height="wrap_content" />
        
    </LinearLayout>
    
</ScrollView>
