数据库中的字符串和可绘制文件夹中的可绘制图像

Question

如何从我的数据库中获取String并将其与我的drawable文件夹中的Image相结合。请帮助。

这是我的主要活动。

public class Grow extends AppCompatActivity {

    private ListView listviewGrow;
    private ListGrowAdapter adapter;
    private List<GrowItem> mGrowItemList;
    private GrowDatabaseHelper mDBHelper;
    private SearchView searchtext;

    Integer[] imgid = {R.drawable.carp,R.drawable.catfish, R.drawable.cavalla };

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        searchtext = (SearchView) findViewById(R.id.search_text);
        super.onCreate(savedInstanceState);
        setContentView(R.layout.grow_layout);
        listviewGrow = (ListView)findViewById(R.id.listview_growtable);
        mDBHelper = new GrowDatabaseHelper(this);

        mGrowItemList = mDBHelper.getListGrow();
        adapter = new ListGrowAdapter(imgid, this, mGrowItemList);
        listviewGrow.setAdapter(adapter);
        listviewGrow.setOnItemClickListener(new AdapterView.OnItemClickListener() {
            @Override
            public void onItemClick(AdapterView<?> adapterView, View row, int position, long index) {
                Toast.makeText(getApplicationContext(), "Position " + position, Toast.LENGTH_SHORT).show();
                Intent intent = new Intent(Grow.this, GrowValueActivityContent.class);
                intent.putExtra("RowId", position);
                startActivity(intent);
            }
        });

    }

这是我的适配器。我不知道该修改什么。希望你能帮助我。
