Android——自定义自适应高度的GridView

public class CustomGridView extends GridView {

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

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

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

@TargetApi(Build.VERSION_CODES.LOLLIPOP)
public CustomGridView(Context context, AttributeSet attrs, int defStyleAttr, int defStyleRes) {
super(context, attrs, defStyleAttr, defStyleRes);
}

@Override
protected void onMeasure(int widthMeasureSpec, int heightMeasureSpec) {
//  AT_MOST参数表示控件可以自由调整大小，最大不超过Integer.MAX_VALUE/4
int height=MeasureSpec.makeMeasureSpec(Integer.MAX_VALUE>>2,MeasureSpec.AT_MOST);
super.onMeasure(widthMeasureSpec, height);
}
}
