java.lang.NoClassDefFoundError

Question

我遇到了07-03 06：16：58.687：E / AndroidRuntime（1729）：java.lang.NoClassDefFoundError：com.example.tottal.baby.care.MySimpleCursorAdapter在我的項目中出現此錯誤。

這是我的MySimpleCursorAdapter類：

public class MySimpleCursorAdapter extends SimpleCursorAdapter {

    public MySimpleCursorAdapter(Context context, int layout, Cursor c,
        String[] from, int[] to) {
        super(context, layout, c, from, to);
    }

    @Override
    public void setViewImage(ImageView image_v, String id) {
         String path = id;

        Log.v("path", path);
        Bitmap b = BitmapFactory.decodeFile(path);
        if (b==null){
        Log.v("tag",";( ");
        }
        else{
        Bitmap resizedBitmap = Bitmap.createScaledBitmap(b, 230, 230, true);
        image_v.setImageBitmap(resizedBitmap);

    }
    }

}

我如何在其他類中使用此適配器類：

String[] from = new String[]{ DbManager.Image_path,DbManager.babyName,DbManager.babydob,DbManager.b_date}; 
        int[] to = new int[] {R.id.list_image, R.id.title,R.id.artist,R.id.duration};                   
        MySimpleCursorAdapter   Adapter = new MySimpleCursorAdapter(this, R.layout.list_row, c1, from, to);  
        updateListitem();
        list.setAdapter(Adapter);
        list.setOnItemClickListener(listOnItemClickListener);}

這是logcat：
