在开发中遇到了ScrollView嵌套GridView的情况,由于这两款控件都自带滚动条,当它们碰到一起的时候便会出问题,即GridView会显示不全。
解决办法,自定义一个GridView控件。
- public class MyGridView extends GridView {
- public MyGridView(Context context, AttributeSet attrs) {
- super(context, attrs);
- }
- public MyGridView(Context context) {
- super(context);
- }
- 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);
- }
- }
该自定义控件只是重写了GridView的onMeasure方法。
- <ScrollView
- android:layout_height="wrap_content"
- android:layout_width="fill_parent"
- android:id="@+id/scroll_content" >
- <com.manoel.MyGridView xmlns:android="http://schemas.android.com/apk/res/android"
- android:id="@+id/grid_view" android:layout_width="fill_parent"
- android:layout_height="wrap_content" android:numColumns="auto_fit"
- android:horizontalSpacing="1dip" android:verticalSpacing="1dip"
- android:columnWidth="150dip" android:stretchMode="columnWidth"
- android:gravity="center" />
- </ScrollView>
- MyGridView gridview = (MyGridView) findViewById(R.id.grid_view);
- gridview.setAdapter(new MyAdapter(this));
