android ScrollVIew中嵌套GridView,如何顯示GridView

 在Android開發當中經常會用到瞭需要ScrollView嵌套GridView或者是ListView的情況,由於這兩款控件都自帶滾動條,當他們一起使用的時候就會出現GridView或ListView會顯示不全的問題。

自定義MyGridView

public class MyGridView extends GridView {

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

    public MyGridView(Context context, AttributeSet attrs) {
        super(context, attrs);
    }
    public MyGridView(Context context, AttributeSet attrs, int defStyle) {
        super(context, attrs, defStyle);
    }
    @Override
    public void onMeasure(int widthMeasureSpec, int heightMeasureSpec) {
 
        int expandSpec = MeasureSpec.makeMeasureSpec(Integer.MAX_VALUE >> 2,
                MeasureSpec.AT_MOST);
        super.onMeasure(widthMeasureSpec, expandSpec);
    }

}

xml中的佈局文件:

<com.xxx.MyGridView
             android:id="@+id/mygridview"
             android:layout_width="fill_parent"
             android:layout_height="wrap_content"
             android:gravity="center"
             android:horizontalSpacing="5dp"
             android:numColumns="4"
             android:stretchMode="columnWidth"
             android:verticalSpacing="6dp" />

 

Java調用代碼

MyGridView gridview = (MyGridView) findViewById(R.id.mygridview);
gridview.setAdapter(new XxxAdapter(xxx));
