android.view.InflateException：バイナリXMLファイル行＃30：バイナリXMLファイル行＃30：エラーinflatingクラス<unknown>

Question

ローカルに保存されたjsonファイルからデータをロードするカスタムアダプタをカードビューで作成しています。私は、データをフェッチすることができていますが、ビューが膨張されていないと、私はこのエラーを取得し続ける：

Answer 1

テキスト外観属性がandroid:textSizeに適用されるべきではありません。これを行う：

 <TextView 
      android:layout_width="wrap_content" 
      android:layout_height="wrap_content" 
      android:textAppearance="?android:textAppearanceLarge" 
      android:id="@+id/textView_event"/> 
     <TextView 
      android:layout_width="wrap_content" 
      android:layout_height="wrap_content" 
      android:textAppearance="?android:textAppearanceSmall" 
      android:id="@+id/textView_time"/> 
     <TextView 
      android:layout_width="wrap_content" 
      android:layout_height="wrap_content" 
      android:textAppearance="?android:textAppearanceSmall" 
      android:id="@+id/textView_venue"/>
