我不明白为什么我会收到类转换异常，因为我只是将 Imageview 分配给 Imageview，但它指出不能将 ImageView 转换为 TextView。

下面是我的 xml 和 Activity 类的代码

</RelativeLayout>

我的活动：

 super.onCreate(savedInstanceState);
         setContentView(R.layout.film_detail);

         ImageView movieImage = (ImageView)findViewById(R.id.imageView1);

我在这条线上遇到了例外。 

 ImageView movieImage = (ImageView)findViewById(R.id.imageView1);

谢谢，阿曼迪普

您 android:id="@+id/txt1"的.xml文件中也有与ImageView&相关联的文件，您应该为两个视图TextView分配不同的id 。

 <ImageView
                android:id="@+id/txt1"
                android:layout_width="30dp"
                android:layout_height="30dp"
                android:background="@drawable/star"
                android:textDirection="firstStrong" />

您在此 ImageView 中将 id 指定为 txt1

那是因为你有相同的 id ( txt1)

android:id="@+id/txt1"

对于一个ImageView和TextView你的xml。将其更改ImageView为其他内容（老实说，txt1不适合作为 ImageView 的 id）。

<ImageView
android:id="@+id/txt1" // my id is txt1
android:layout_width="30dp"
android:layout_height="30dp"
android:background="@drawable/star"
android:textDirection="firstStrong" />
....
<TextView
android:id="@+id/txt1" // gosh, my id is txt1 too. :(
android:layout_width="30dp"
android:layout_height="30dp"
android:background="@drawable/star"
android:gravity="center"
android:text=""
android:textAlignment="center"
android:textColor="@color/titlebackgroundcolor"
android:textDirection="firstStrong" />
