我使用以下 xml 制作了一个自定义视图

<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:id="@+id/packetlayout"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical" >

<View
    android:id="@+id/view2"
    android:layout_width="1dip"
    android:layout_height="fill_parent"
    android:background="#FF0000FF" />

<TextView
    android:id="@+id/textView1"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:layout_alignBottom="@+id/tempEdit"
    android:layout_marginLeft="10dp"
    android:layout_toRightOf="@+id/view2"
    android:text="Temp : "
    android:textAppearance="?android:attr/textAppearanceSmall" />

<EditText
    android:id="@+id/timeEdit"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:layout_alignLeft="@+id/tempEdit"
    android:layout_alignParentBottom="true"
    android:layout_alignRight="@+id/drawingCanvas"
    android:ems="5"
    android:textAppearance="?android:attr/textAppearanceSmall" />

<EditText
    android:id="@+id/tempEdit"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:layout_toRightOf="@+id/textView1"
    android:ems="5"
    android:text="115"
    android:textAppearance="?android:attr/textAppearanceSmall"
    android:width="50dp"
    android:inputType="number" />

<TextView
    android:id="@+id/textView2"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:layout_alignBaseline="@+id/timeEdit"
    android:layout_alignBottom="@+id/timeEdit"
    android:layout_alignLeft="@+id/drawingCanvas"
    android:text="Time : "
    android:textAppearance="?android:attr/textAppearanceSmall" />

<LinearLayout
    android:id="@+id/drawingCanvas"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:layout_above="@+id/timeEdit"
    android:layout_alignLeft="@+id/textView1"
    android:layout_alignRight="@+id/tempEdit"
    android:layout_below="@+id/textView1"
    android:orientation="vertical" 
    android:layout_marginRight="15dp">

</LinearLayout>

我想将它们的多个副本插入带有 Linearlayout 的 ScrollView。

由于屏幕尺寸不同，我知道我们必须使用 onmeasure 覆盖相应地缩放它们。

    @Override
protected void onMeasure(int widthMeasureSpec, int heightMeasureSpec) {
    // TODO Auto-generated method stub
    super.onMeasure(widthMeasureSpec, heightMeasureSpec);

    // get width and height size and mode
    int wSpec = MeasureSpec.getSize(widthMeasureSpec);

    int hSpec = MeasureSpec.getSize(heightMeasureSpec);
    int hMode = MeasureSpec.getMode(heightMeasureSpec);

    int width = wSpec;
    int height = hSpec;

    // ideal height for the number display
    int idealHeight = (int) (wSpec * 1);

    if(idealHeight < hSpec)
    {
        height = idealHeight;
    }

    Log.e("logging " , wSpec + "   " + hSpec + "   " + hMode + "   " + width + "  " + height);
    setMeasuredDimension(wSpec / 2, hSpec/2);
}

使用上面的代码，我总是得到 wSpec = 0 和 hSpec = 382。

我怎样才能获得我想将我的 CustomView 插入的 LinearLayout 的大小？

谢谢
