具有ImageView的ListView-如何将不同的链接放置到列表中的每个ImageView

Question

我正在做我的第一个项目。我需要个建议。我的应用程序应向用户显示运动，当用户点击左侧的“播放”图标时，应用程序应按意图移至youtube到视频，以向用户展示如何正确进行运动。这是一些代码。

构造函数

public class Constructor {

private String mExcersiseName;
private String mBodyPart;
private String mYoutubeLink;

public Constructor(String excersiseName, String bodyPart, String youtubeLink){
    mExcersiseName = excersiseName;
    mBodyPart = bodyPart;
    mYoutubeLink = youtubeLink;
}

public String getExcersiseName(){
    return mExcersiseName;
}
public String getBodyPart(){
    return mBodyPart;
}
public String getYoutubeLink(){return mYoutubeLink;}
}

适配器

public class ExerciseAdapter extends ArrayAdapter<Constructor>{
String mYoutubeLink;

public ExerciseAdapter(Activity context, ArrayList<Constructor> constructorList) {
    super(context, 0, constructorList);
    mYoutubeLink = youtubeLink;
}

@NonNull
@Override
public View getView(int position, @Nullable View convertView, @NonNull ViewGroup parent) {
    View listItem = convertView;
    if (listItem == null) {
        listItem = LayoutInflater.from(getContext()).inflate(R.layout.items_for_list, parent, false);

    }
    Constructor actualPosition = getItem(position);

    TextView exerciseName = (TextView) listItem.findViewById(R.id.list_excersise_name);
    exerciseName.setText(actualPosition.getExcersiseName());

    TextView bodyPart = (TextView) listItem.findViewById(R.id.list_body_part);
    bodyPart.setText(actualPosition.getBodyPart());

    return listItem;
}
}

我们在其中放置运动名称，身体部位和youtube链接等数据的Java类

public class BicepsActivity extends AppCompatActivity {

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.list_item);

    ArrayList<Constructor> bicepsExercises = new ArrayList<Constructor>();
    bicepsExercises.add(new Constructor("Lorem ipsum","Lorem","link"));
    bicepsExercises.add(new Constructor("Lorem ipsum","Lorem","link"));
    bicepsExercises.add(new Constructor("Lorem ipsum","Lorem","link"));
    bicepsExercises.add(new Constructor("Lorem ipsum","Lorem","link"));
    bicepsExercises.add(new Constructor("Lorem ipsum","Lorem","link"));
    bicepsExercises.add(new Constructor("Lorem ipsum","Lorem","link"));
    bicepsExercises.add(new Constructor("Lorem ipsum","Lorem","link"));

    ExerciseAdapter adapter = new ExerciseAdapter(this,bicepsExercises);

    ListView list = (ListView) findViewById(R.id.list_item);
    list.setAdapter(adapter);
}

}
