java - 如何从 OnItemClickListener 使 imageView 可点击？

Question

lv.setOnItemClickListener(new AdapterView.OnItemClickListener() {
        @Override
        public void onItemClick(final AdapterView<?> parent, View view, final int position, long id) 
        {

         // My code is here. I want make my image clickable. I don't want make it clickable in my CustomAdapter getView() method because it doesn't allows me open DialogFragment from there.
         // I already setted in xml of image clickable="true" and focusable = "false"
         //I'll admit for any help and thanks in advance

        }
}

Answer 1

如果您从适配器获取图像 Onclick，则不能从列表视图事件中获取 setOnItemClickListener。我建议您可以使用 Onclick，而不是 setOnItemClickListener 从适配器获取 Onclick。

Answer 2

首先，您必须OnClickListener在 Adapter 类中添加 Imageview，例如

viewHolder.button1.setOnClickListener(new OnClickListener() {

@Override
public void onClick(View v) {
    ((ListView) parent).performItemClick(v, position, 0); // Let the event be handled in onItemClick()
}

});

然后在你可以访问 ImageViewonItemClick之后

@Override
public void onItemClick(AdapterView<?> parent, View view, int position, long id) {
    long viewId = view.getId();


if (viewId == R.id.button1) {
        Toast.makeText(this, "Button 1 clicked", Toast.LENGTH_SHORT).show();
    } else if (viewId == R.id.button2) {
        Toast.makeText(this, "Button 2 clicked", Toast.LENGTH_SHORT).show();
    } else {
        Toast.makeText(this, "ListView clicked" + id, Toast.LENGTH_SHORT).show();
    }
}

享受！...

从适配器显示对话框应该不是问题。如果您的适配器需要一些它没有的东西，那么您可以为您的适配器添加一个带有一些监听器的字段，private final OnImageClickListener并创建一个接口：

public interface OnImageClickListener {
    void onImageClicked(View view, int position, int id);
}

当您从您的活动或片段创建适配器时，您可以在您的活动/片段或匿名类中实现此接口，并且在那里您可以访问片段管理器并可以做任何您想做的事情。
