Android-inflate一個View之後,怎么在沒有显示出来的时候获取他的height

Question

View item = LayoutInflater.from(getActivity()).inflate(R.layout.perrsonal_center_gridview_item, null);
item.measure(MeasureSpec.AT_MOST, MeasureSpec.EXACTLY);
int height = item.getMeasuredHeight();
Log.i("zj", "height = " + height);

log打印出来为0

界面如下:

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="wrap_content"
    android:layout_height="50dp"   ***这里最开始是wrap_content后来改成了50dp***
    android:gravity="center" >
    <LinearLayout 
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:orientation="vertical"    
        android:gravity="center"
    >
        <ImageView 
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:src="@drawable/ic_launcher"    
            android:scaleType="centerInside"
        />
        <TextView 
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:text="我的消息"    
        />
    </LinearLayout>
</LinearLayout>

已經找到辦法了, EXACTLY改为UNSPECIFIED就ok了
