我使用以下類來顯示自定義日曆，但使用此後我得到的錯誤在膨脹類異常。使用以顯示的日曆視圖Android InflateException二進制XML文件行
<?xml version="1.0" encoding="utf-8"?>

CalendarCustomView類用於在活動設置日曆和表示事件表示日曆
public class MainActivity extends AppCompatActivity {
private static final String TAG = MainActivity.class.getSimpleName();
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
//Getting error here for inflating
setContentView(R.layout.activity_main);
//Inflating this class from another
CalendarCustomView mView = (CalendarCustomView)findViewById(R.id.custom_calendar);
