Android:带有可点击网格项和嵌套视图(按钮、复选框)的网格视图 [英] Android: Grid view with clickable grid items and nested views (buttons, checkboxes)

问题描述

基本上，我想实现一个 GridView，其中项目本身是可点击的，但在 GridView 中是可点击的 Buttons 和 <代码>复选框es.

Basically, I would like to implement a GridView wherein the items themselves are clickable, but within the GridView are clickable Buttons and Checkboxes.

这是一个示例布局:

Gridview
-----------------------------------------
|[ImageView]        |[ImageView]        |
|[TextView]         |[TextView]         |
|[Button][Checkbox] |[Button][Checkbox] |
-----------------------------------------
|[ImageView]        |[ImageView]        |
|[TextView]         |[TextView]         |
|[Button][Checkbox] |[Button][Checkbox] |
-----------------------------------------

基本上，我想要做的是，当用户单击CheckBox 时，现在可以从GridView 中选择多个项目.当用户单击Button 时，会显示一个Popup.当用户点击其他任何地方时，就会启动一个新的 Activity.这样做的全部意义不是长按以显示上下文菜单，而是想要一个按钮来代替它.

Basically, what i want to do is, when the user clicks the CheckBox, multiple items can now be selected from the GridView. When the users clicks the Button, A Popup is shown. When the user clicks anywhere else, a new Activity is started. The whole point of this is instead of long-pressing to show the context menu, I would like a button to take its place.

关于如何处理这种情况有什么建议吗?在我当前的设置中，如果我在适配器的 GetView() 方法中添加 Button，则只有 Button 是可点击的.整个 GridView 项目是不可点击的.当我删除 Button 时，GridView 项可以再次点击.似乎只有整个 GridView Item 或 Button 是可点击的(响应 OnClickListener().有没有办法让它们都可点击?

Any suggestions on how I can approach this scenario? In my current setup, if I add the Button within the adapter's GetView() method, only the Button is clickable. The whole GridView item is not clickable. When I remove the Button, the GridView item is clickable again. It seems that it's only the whole GridView Item or the Button is clickable (responds to OnClickListener(). Is there a way to make them both clickable?

推荐答案

这篇文章很旧，但仅供参考/googlers，我有以下解决方案:

This post is old, but just for reference/googlers, I have the following solution:

您只需要在 imageAdapter 的 getView 中编写按钮的所有事件，复选框.然后在 gridview 标签下的 layout.xml 文件中添加以下几行:

You need to write all the events for buttons, checkboxes in getView of the imageAdapter only. Then in your layout.xml file under the gridview tag add these lines:

android:clickable="true"
android:descendantFocusability="beforeDescendants"

并将这些行添加到您的按钮和复选框中:

and add these lines to your button and checkboxes:

android:focusable="false"
android:focusableInTouchMode="false"

如果您希望在单击/触摸 gridview 项目的任何其他区域时启动其他活动，则需要使用(标准代码)/(您自己的匹配实现):

And if you want some other activity to start if any other area of the gridview item is clicked/touched you would need to use the (standard code)/(your own matching implementation):

GridView gridview = (GridView) findViewById(R.id.gridview);
    gridview.setAdapter(new ImageAdapter(this));

    gridview.setOnItemClickListener(new OnItemClickListener() {
        public void onItemClick(AdapterView<?> parent, View v, int position, long id) {
            Toast.makeText(HelloGridView.this, "" + position, Toast.LENGTH_SHORT).show();
        }

干杯，});
