我試圖在我的應用程序中創建一個自定義的ViewPager。我看過以下文章，這似乎是我正在嘗試做的。 Custom ViewPagerViewPager strife
運行時出現ClassCastException。我試圖膨脹一個線性佈局，我猜這是問題，因爲它實際上不是一個視圖，它是一個視圖組。請有人告訴我我要去哪裏錯了？
感謝，
<?xml version="1.0" encoding="utf-8" ?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" android:layout_width="match_parent" android:layout_height="match_parent" android:orientation="vertical">
<TextView android:layout_width="wrap_content" android:layout_height="wrap_content" android:text="TextView1" android:textAppearance="?android:attr/textAppearanceLarge" android:id="@+id/textView1"></TextView>
<TextView android:layout_width="wrap_content" android:layout_height="wrap_content" android:text="TextView2" android:textAppearance="?android:attr/textAppearanceLarge" android:id="@+id/textView2"></TextView>
</LinearLayout>

@Override
public Object instantiateItem(View collection, int position) {
LayoutInflater inflater = (LayoutInflater)
cxt.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
View layout = inflater.inflate(R.layout.animallayout, null);
TextView tv1 = (TextView) layout.findViewById(R.id.textView1);
TextView tv2 = (TextView) layout.findViewById(R.id.textView2);
tv1.setText("test 1");
tv2.setText("test 2");
((ViewPager) collection).addView(layout, 0);
return layout;
}
