Question

我希望通过外部按钮从视图的当前项目接收信息，因为它显示图像，按钮位于适配器之外。任何人都可以帮助我吗？

    public void setImage(String image) {

非常感谢所有人，问候！

您可以使用ListView的setOnItemClickListener获取信息，使用外部按钮显示显示详细信息的界面。

我们只是说：

ListView list = (ListView) findViewById(R.id.listview);
list.setOnItemClickListener(new AdapterView.onItemClickListener() {
   @Override
   public void onItemClick(AdapterView<?> adapter, View view, int position, long arg) {
      Object listItem = list.getItemAtPosition(position);
   } 
});
