public final int getMeasuredHeight ()
Added in API level 1
Like getMeasuredHeightAndState()
, but only returns the raw width component (that is the result is masked by MEASURED_SIZE_MASK
).
Returns
- The raw measured height of this view.
public final int getHeight ()
Added in API level 1
Return the height of your view.
Returns
- The height of your view, in pixels.
getMeasuredHeight()返回的是原始测量高度,与屏幕无关,getHeight()返回的是在屏幕上显示的高度。实际上在当屏幕可 以包裹内容的时候,他们的值是相等的,只有当view超出屏幕后,才能看出他们的区别。当超出屏幕后,getMeasuredHeight()等于 getHeight()加上屏幕之外没有显示的高度。
例:
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="240dip"
android:clipToPadding="false"
android:scrollY="50dip" >
</RelativeLayout>
这里设置它的高度为240dip,超出屏幕50dip。
getMeasuredHeight()获得的就是240dip的大小。(转换为像素值)
getHeight()获得的是240dip - 50dip的大小。(转换为像素值)
