如何在Android中构建此布局?
我找到了Fedor的代码并在我的项目中实现了它。唯一的区别是我的应用程序没有列表视图 我希望显示器看起来像下图: 我该怎么做 ImageAdapter.class如何在Android中构建此布局?,android,Android,我找到了Fedor的代码并在我的项目中实现了它。唯一的区别是我的应用程序没有列表视图 我希望显示器看起来像下图: 我该怎么做 ImageAdapter.class public class ImageAdapter extends BaseAdapter { private Activity activity; // private Context context; private ArrayList<HashMap<String, String>> data; //

公共类ImageAdapter扩展了BaseAdapter{

私用静态充气机充气=空;
公众形象;
公共图像适配器(活动ac,ArrayList d){
本活动=ac;
这个数据=d;
充气=(充气)活动

创建时受保护的void(Bundle savedInstanceState){

试一试{
result=json.getJSONObject(“结果”);

字符串计数=result.getString(“计数”);
String page=result.getString(“page”);
JSONArray ketqua=result.getJSONArray(“ketqua”);
对于(int i=0;i
}
这段代码我可以用Gridview显示图像。
但我可以自定义它看起来像下面的布局
现在我需要一个自定义布局和显示

所有这些部分应该是什么?文本视图?图像视图?需要更多信息。我需要在Imageview中显示。每个单元格中有一个图像。嘿,伙计。你能帮我发送你的Skype或Yahoo吗……我有个问题……请帮我添加代码,以便使用Imageview.setImageUR动态查找图像视图并设置imagestry我(uri)或者请上传一些代码片段来展示你是如何加载图片的。你能和我聊天吗…帮帮我吗?
