重写GridView的onMeasure的方法:

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);
}
}
