您好，我创建了一个网格视图应用程序。它在我的网格视图中显示我的 SD 卡图像，现在我只有 10 个图像。如果我在网格视图中单击第一张图像，我想使用文本视图显示一个段落。然后我单击第二张图像，我想显示另一段......所以我创建一个 xml 文件，该 xml 文件有 10 段。我的疑问如何显示这一段？当我单击该 gridview 图像时，我希望显示该图像，仅此而已......

首先，您必须解析 xml 并将所有段落数据存储到数组或 Arralist 中。

编写Gridview的onItemclickListener事件，并在grid的onItemClickListener中显示自定义对话框。

在自定义对话框中，您必须使用文本视图设置一个 xml 文件。

此外，您还必须在 onItemclickListener 中设置该 TextView 的值。

您必须借助侦听器的索引参数来获取数据。

gridView.setOnItemClickListener(new OnItemClickListener() {
    @Override
    public void onItemClick(AdapterView<?> arg0, View arg1, int arg2,
                long arg3) {
            //get the data for textView by passing index in  para[index]
            //use the custom dialog  to show the your paragraph
        }
    });

First of all you have to parse your xml and store all the paragraph data into array or arralist.

Write the onItemclickListener event of Gridview and display the Custom dialog in grid's onItemClickListener.

In Custom dialog, you have to set one xml file with textview.

Also, you have to set the value of that TextView in onItemclickListener.

You have to get the data with the help of the the index argument of the listener.

gridView.setOnItemClickListener(new OnItemClickListener() {
    @Override
    public void onItemClick(AdapterView<?> arg0, View arg1, int arg2,
                long arg3) {
            //get the data for textView by passing index in  para[index]
            //use the custom dialog  to show the your paragraph
        }
    });

创建如下的 xml 结构：

<paragraph>

<par> dkdkkddkdkkdkkdkdkkdkdkdkdkdkdkdk] dkdkkdkdkdkdkkdkdkdkdkdkdkdkdk </par>

<par> skjdkjfidfdjfkdjfoiudifjieiiejriej dkiekdikdididkdkdkipppw;wpp;eokkll </par> . . . . . <par> dkdi;;iathehe thid tihoodfjalkjfkjdfk dkjfldkjflkjdalkjldkjoaiuidfiudofuoia </par> </paragraph>

然后将这些字符串解析为数组列表，并根据图像的选择位置，显示索引中的段落。

Create your xml structure as below:

<paragraph>

<par> dkdkkddkdkkdkkdkdkkdkdkdkdkdkdkdk] dkdkkdkdkdkdkkdkdkdkdkdkdkdkdk </par>

<par> skjdkjfidfdjfkdjfoiudifjieiiejriej dkiekdikdididkdkdkipppw;wpp;eokkll </par> . . . . . <par> dkdi;;iathehe thid tihoodfjalkjfkjdfk dkjfldkjflkjdalkjldkjoaiuidfiudofuoia </par> </paragraph>

Then Parse these strings into an arraylist, and according to the selection position of image, display paragraph from index.
