前端之家收集整理的这篇文章主要介绍了
自定义XML文件,
前端之家小编觉得挺不错的,现在分享给大家,也给大家做个参考。
1、创建xml
文件内容,books.xml
- <?xml version="1.0" encoding="utf-8"?>
- <books>
- <book price="99.0" data="2008年">正见-佛陀的证悟</book>
- <book price="89.0" data="2008年">遇见未知的自己</book>
- <book price="69.0" data="2008年">不一样的烟火</book>
- </books>
2、显示的布局xml文件
- <?xml version="1.0" encoding="utf-8"?>
- <LinearLayout
- xmlns:android="http://schemas.android.com/apk/res/android"
- xmlns:tools="http://schemas.android.com/tools"
- android:layout_width="match_parent"
- android:layout_height="match_parent"
- android:paddingLeft="@dimen/activity_horizontal_margin"
- android:paddingRight="@dimen/activity_horizontal_margin"
- android:paddingTop="@dimen/activity_vertical_margin"
- android:paddingBottom="@dimen/activity_vertical_margin"
- android:orientation="vertical"
- tools:context="com.ui.demo.custom.XmlResActivity">
- <Button
- android:id="@+id/button"
- android:layout_width="wrap_content"
- android:layout_height="wrap_content"
- android:text="获取资源"
- android:onClick="getResource"/>
- <TextView
- android:layout_width="wrap_content"
- android:layout_height="wrap_content"
- android:id="@+id/show"/>
- </LinearLayout>
3、读取xml
内容
- public class XmlResActivity extends Activity
- {
-
- @Override
- protected void onCreate(Bundle savedInstanceState)
- {
- super.onCreate(savedInstanceState);
- setContentView(R.layout.activity_xml_res);
- }
-
- public void getResource(View view)
- {
- //根据XMl资源的ID获取解析该资源的解析器
- XmlResourceParser xmlResourceParser = getResources().getXml(R.xml.books);
- StringBuilder stringBuilder = new StringBuilder("");
- try
- {
- while (xmlResourceParser.getEventType() != XmlPullParser.END_DOCUMENT)
- {
- //还没有到Xml文档的结尾处
- if (xmlResourceParser.getEventType() == XmlPullParser.START_TAG)
- {
- String tagName = xmlResourceParser.getName();
- //如果是books标签
- if (tagName.equals("book"))
- {
- String bookName = xmlResourceParser.getAttributeValue(null,"price");
- stringBuilder.append("价格:");
- stringBuilder.append(bookName);
-
- String bookPrice = xmlResourceParser.getAttributeValue(null,"data");
- stringBuilder.append(" 出版日期:");
- stringBuilder.append(bookPrice);
- stringBuilder.append(" 书名:");
- stringBuilder.append(xmlResourceParser.nextText());
- }
- stringBuilder.append("\n");
- }
- xmlResourceParser.next();
- }
- TextView show = (TextView) findViewById(R.id.show);
- show.setText(stringBuilder.toString());
- }
- catch (XmlPullParserException | IOException e)
- {
- e.printStackTrace();
- }
-
- }
- }
