Question

我正在尝试将一组图像显示为ListView到ListView，有人可以帮助我吗？

这是我的CustomList.java

public class CustomList extends ArrayAdapter<String>{

private final Activity context;
private final String[] web;
private final Integer[] imageId;
public CustomList(Activity context, String[] web, Integer[] imageId) {
    super(context, R.layout.mylist, web);
    this.context = context;
    this.web = web;
    this.imageId = imageId;

}
@Override
public View getView(int position, View view, ViewGroup parent) {
    LayoutInflater inflater = context.getLayoutInflater();
    View rowView= inflater.inflate(R.layout.mylist, null, true);
    TextView txtTitle = (TextView) rowView.findViewById(R.id.txt);

    ImageView imageView = (ImageView) rowView.findViewById(R.id.img);
    txtTitle.setText(web[position]);
    imageView.setImageResource(imageId[position]);
    return rowView;
}

}

以下是mainActivity.java的一些代码

ListView list;
ImageView image;
String[] web = {
        "Google Plus",
        "Twitter",
        "Windows",
        "Bing",
        "Itunes",
        "Wordpress",
        "Drupal"
} ;
Integer[] imageId = {
        R.drawable.image1,
        R.drawable.image2,
        R.drawable.image3,
        R.drawable.image4,
        R.drawable.image5,
        R.drawable.image6,
        R.drawable.image7

};

CustomList adapter = new CustomList(this, web, imageId);
        list=(ListView)findViewById(R.id.list);
        list.setAdapter(adapter);

我的所有图片都是Bitmap类型，我希望将它们放在imageId数组上以显示在Custom ListView上

Answer 1

使用 int [] 数组而不是 Integer [] 数组，

tooltips=false

也会在 CustomList.java 文件

中进行相应的更改
