试过在OnCreate()中获取控件高度与宽度的童鞋都知道,getWidth()与getHeight()方法返回是0,具体原因
看一下Activity的生命周期 就会明白。
上代码:
方法一:
int w = View.MeasureSpec.makeMeasureSpec(0,View.MeasureSpec.UNSPECIFIED);
int h = View.MeasureSpec.makeMeasureSpec(0,View.MeasureSpec.UNSPECIFIED);
ssidtext.measure(w, h);
int width =ssidtext.getMeasuredWidth();
int height =ssidtext.getMeasuredHeight();
方法二:
ViewTreeObserver vto = ssidtext.getViewTreeObserver();
vto.addOnPreDrawListener(new ViewTreeObserver.OnPreDrawListener() {
public boolean onPreDraw() {
int height = ssidtext.getMeasuredHeight();
int width = ssidtext.getMeasuredWidth();
return true;
}
});
具体用哪一种可以根据需求自己选择。
