java - Android/Java - 单击 ListView 中的图像

Question

我在 Android Studio 中制作了一个 ListView 。 ListView 的每个项目都有一个图像，但我不知道如何使其可点击。我确实在互联网上浏览了解决方案，但困难的部分似乎是在我自己的代码中实现它。我无法弄清楚。

相关图像 = ex_img

--请记住，当单击图像时，它还应该知道其在列表中的位置。

感谢您的阅读，希望您能帮助我。

列表适配器:

public class CustomList extends ArrayAdapter<String> {
    private String[] ex_name;
    private String[] ex_diff;
    private String[] ex_muscle;
    private String[] ex_dpr;
    private Integer[] ex_img;
    private Activity context;

    public CustomList(Activity context, String[] ex_name, String[] ex_diff, String[] ex_muscle, String[] ex_dpr,
                      Integer[] ex_img) {
        super(context, R.layout.row_layout, ex_name);
        this.context = context;
        this.ex_name = ex_name;
        this.ex_muscle = ex_muscle;
        this.ex_diff = ex_diff;
        this.ex_dpr = ex_dpr;
        this.ex_img = ex_img;

    }
//LIST --> XML
    @Override
    public View getView(int position, View convertView, ViewGroup parent) {
        LayoutInflater inflater = context.getLayoutInflater();
        View listViewItem = inflater.inflate(R.layout.row_layout, null, true);
        TextView list_name = (TextView) listViewItem.findViewById(R.id.ex_name);
        TextView list_diff = (TextView) listViewItem.findViewById(R.id.ex_diff);
        TextView list_muscle = (TextView) listViewItem.findViewById(R.id.ex_muscle);
        ImageView list_image = (ImageView) listViewItem.findViewById(R.id.ex_img);
        TextView list_dpr = (TextView) listViewItem.findViewById(R.id.ex_dpr);

        list_name.setText(ex_name[position]);
        list_muscle.setText(ex_muscle[position]);
        list_diff.setText(ex_diff[position]);
        list_dpr.setText(ex_dpr[position]);
        list_image.setImageResource(ex_img[position]);

        return  listViewItem;

    }
}

可能需要的 MainActivity 部分:

 private Integer img[] = {
            R.drawable.ic_favorite_white_24dp,
            R.drawable.ic_location_on_white_24dp,
            R.drawable.ic_update_white_24dp,
            R.drawable.ic_local_dining_white_24dp,
            R.drawable.ic_local_dining_white_24dp

    };


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

        CustomList customList = new CustomList(this, name, diff, muscle, dpr, img);

        listView = (ListView) findViewById(R.id.listview);
        listView.setAdapter(customList);

        listView.setOnItemClickListener(new AdapterView.OnItemClickListener() {
            @Override
            public void onItemClick(AdapterView<?> adapterView, View view, int i, long l) {
                Toast.makeText(getApplicationContext(),"You Clicked "+name[i],Toast.LENGTH_SHORT).show();
            }
        });
    }

Answer 1

将 onClickListener 添加到 getView() 中的 ImageView -

list_image.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {
                //Here you have the position too.
});

只需将getView()中的position参数设为final即可
