android – 使用adapterview时无法在视图组中绘制子视图

我正在尝试使用适配器视图正确绘制其子视图,但是无法获取适配器返回的视图的子视图以进行绘制.具体来说,我的适配器应该吐出这样的简单视图：

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://scheR_543_11845@as.android.com/apk/res/android"
    android:layout_width="fill_parent"
    android:layout_height="fill_parent"
    android:BACkground="#FFFFFF">

        <TextView
            android:id="@+id/photo_cell_contents"
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:layout_marginTop="10px" 
            android:text="@String/photo_cell_default_text" 
            android:textColor="#000000" 
            android:textSize="80px"/>

</LinearLayout>@H_262_8@ 
 
适配器的getView()方法确实被调用,并确实将此视图的实例返回到适配器视图.我还在我的适配器视图中添加了断点,并且可以看到那里存在正确的视图层次结构 – 带有子textview对象的根线性布局.但是,当适配器视图布局并绘制适配器返回的子视图时,不会绘制内部文本视图.我看到对应于每个单元格的实际彩色框,但不是应该出现在内部的文本.有谁知道为什么会发生这种情况？下面是适配器视图的onLayout()方法中的代码,它放置子视图(当我在setAdapter()时添加它们,并在我滚动适配器视图时得到更新)：
 
 
 
 
for (int idx = 0; idx < this.getChildCount(); idx++) {
        if (idx != dragged)
        {
            Point xy = getCoorFromIndex(idX);
            View child = getChildAt(idX);
            child.layout(xy.x,xy.y,xy.x + childSize,xy.y + childSizE); //view group will layout the children based on the sizes determined for available columns
            int left = child.getLeft();
            int right = child.getright();
            int top = child.getTop();
            View tv = ((ViewGroup)child).getChildAt(0);
            int tvleft = tv.getLeft();
            int tvright = tv.getright();
            int tvtop = tv.getTop();

            Log.i("dgv","Here is info about main view ... left =  " + left + "; right = " + right + "; top = " + top);
            Log.i("dgv","Here is info about text view ... left =  " + tvleft + "; right = " + tvright + "; top = " + tvtop);


        }
