我正在努力自定义 Gird 视图。不完全是自定义 Gird 视图，而是子视图的单击事件。
主要两个查询：
第一：
问题是如果我在网格中添加简单的图像视图和文本视图，然后单击它工作的任何项目并向我显示该项目的位置。但是当我在网格中添加两个按钮替换不会调用项目的简单单击事件的文本视图时，按钮。
第二：
我想获得所有三个视图（如图像和两个按钮）的点击事件。如果我单击图像，它应该执行一些任务，并且与两个按钮相同。
看到我有这个代码。

我试图找到东西，但没有成功。 如何实现这一点.
感谢您访问我的查询
例如在
你得到视图
viewHolder.checkbox.setOnCheckedChangeListener(listenerCheckBox);
和侦听器
OnCheckedChangeListener listenerCheckBox = new OnCheckedChangeListener() {
public void onCheckedChanged(CompoundButton buttonView,
boolean isChecked) {
}
};
例如，你item_grid
public class Item {
private String title;
private String description;
private Date pubDate;
private String link;
public Item(String title, String description, Date pubDate, String link) {
this.title = title;
this.description = description;
this.pubDate = pubDate;
this.link = link;
}
public String getTitle() {
return this.title;
}
public String setTitle(String title_) {
this.title = title_;
}
}
\
如果你的情况
if (convertView == null) {
view = new ViewHolder();
convertView = inflator.inflate(R.layout.grid_item, null);
view.imgViewFlag = (ImageView) convertView
.findViewById(R.id.imageView1);
view.txt = (TextView) convertView
.findViewById(R.id.grid_item_label);
view.btn1 = (Button) convertView.findViewById(R.id.button1);
view.btn2 = (Button) convertView.findViewById(R.id.button2);
view.btn1.setOnClicListener(myClickListener);
convertView.setTag(view);
} else
\
private OnClickListener myClickListener = new OnClickListener() {
public void onClick(View v) {
}
};
