内部相对布局未定义和缺少控件

Question

这是我的xml代码

<?xml version="1.0" encoding="utf-8"?>


        <RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
                        android:id="@+id/RelativeLayout01" 
                        android:layout_width="fill_parent"                       
                        android:layout_height="fill_parent"

            <ImageButton

                        android:layout_alignRight="@id/fchelpdown">
            </ImageButton>
            </RelativeLayout>



            <ImageView
                        android:id="@+id/android"
                        android:layout_width="fill_parent" 
                        android:layout_height="48dp" 
                        android:background="@drawable/android"
                        android:layout_alignBottom="@id/default1">


                            </ImageView> 

        </RelativeLayout>

我有2个问题

1. RelativeLayout02未定义如下所示，但它是在@+id/postscore

之后出现的

2. 我看不到@+id/fcsoundondown"和@+id/fcboards_down

Answer 1

没有此类ID fcleaderboards_down ，您已在图片按钮android:layout_alignBottom="@id/fcleaderboards_down"中使用了它。
