android WebView设置最大高度

当我们在dialog中嵌入webview来显示网页信息时,如果网页内容足够长,则会出现dialog高度被撑满屏,但是介于美观问题,我们会试图动态设置webview的最大高度,可是遗憾的是,谷歌并没有给我们提供这个方法,聪明人想出了聪明的办法,具体请看下面代码:

public class MyWebView extends WebView {
	private int mMaxHeight = -1;

	public MyWebView(Context context) {
		super(context);
		// TODO Auto-generated constructor stub
	}
	public MyWebView(Context context, AttributeSet attrs) {
		super(context, attrs);
		// TODO Auto-generated constructor stub
	}
	
	public MyWebView(Context context, AttributeSet attrs, int defStyle) {
		super(context, attrs, defStyle);
		// TODO Auto-generated constructor stub
	}
	
	public MyWebView(Context context, AttributeSet attrs, int defStyle,
			boolean privateBrowsing) {
		super(context, attrs, defStyle, privateBrowsing);
		// TODO Auto-generated constructor stub
	}
	
	public void setMaxHeight(int height){
		mMaxHeight = height;
	}
	
	@Override
	protected void onMeasure(int widthMeasureSpec, int heightMeasureSpec) {
		// TODO Auto-generated method stub
		super.onMeasure(widthMeasureSpec, heightMeasureSpec);
		
		if(mMaxHeight>-1 && getMeasuredHeight()>mMaxHeight){
			setMeasuredDimension(getMeasuredWidth(), mMaxHeight);
		}
	}	
}
结果,世界和平了 微笑

友情提示:设置最大高度一定要在加载内容之前!!!
