1.先看下最终要达到的效果图:
2.新建Activity布局文件activity_common_info.xml
<? xml version= "1.0" encoding= "utf-8" ?>< LinearLayout xmlns:android= "http://schemas.android.com/apk/res/android"android:layout_width= "match_parent"android:layout_height= "match_parent"android:background= "#eee"android:orientation= "vertical" ><ScrollViewandroid:layout_width= "fill_parent"android:layout_height= "fill_parent"android:scrollbars= "@null" ><LinearLayoutandroid:id= "@+id/ll_content"android:layout_width= "fill_parent"android:layout_height= "wrap_content"android:orientation= "vertical"android:paddingLeft= "20dip"android:paddingRight= "20dip"android:paddingTop= "20dip" ></LinearLayout ></ScrollView ></ LinearLayout>
3.创建实体类RowItem.java 包含两个成员变量key和value，如key是"姓名"，value是"张三"。
public class RowItem {private String key;private String value;public RowItem(String key, String value) {super();this. key = key;this. value = value;}public String getKey() {return key;}public String getValue() {return value;}}
4.创建行布局,本文为了美观用到三种行样式，这里仅提供一种样式布局如下，其他两个类似。
<? xml version= "1.0" encoding= "utf-8" ?>< LinearLayout xmlns:android= "http://schemas.android.com/apk/res/android"android:layout_width= "match_parent"android:layout_height= "match_parent"android:orientation= "vertical" ><LinearLayoutandroid:layout_width= "fill_parent"android:layout_height= "wrap_content"android:background= "@drawable/about_mid_bg"android:gravity= "center_vertical"android:orientation= "horizontal"android:padding= "8dip" ><TextViewandroid:id= "@+id/tv_key"android:layout_width= "60dip"android:layout_height= "30dip"android:layout_marginLeft= "8dip"android:gravity= "center_vertical"android:textColor= "#222222"android:textSize= "14sp" /><TextViewandroid:id= "@+id/tv_value"android:layout_width= "fill_parent"android:layout_height= "30dip"android:gravity= "center_vertical"android:paddingLeft= "8dip"android:textColor= "#333333"android:textSize= "14sp" /></LinearLayout ></ LinearLayout>
5.创建自动生成行的工具类CreateViewUtil.java
public class CreateViewUtil {public static void createContentView(Context context,LinearLayout contentLayout,List<RowItem> rowItemList) {View childView;TextView keyTv;TextView valueTv;LayoutInflater layoutInflater;layoutInflater = LayoutInflater. from(context);for ( int i = 0; i < rowItemList.size(); i++) {if (i == 0) {childView = layoutInflater.inflate(R.layout.row_top_item , null);} else if (i == (rowItemList.size() - 1)) {childView = layoutInflater.inflate(R.layout.row_bottom_item , null );} else {childView = layoutInflater.inflate(R.layout.row_mid_item , null);}keyTv = (TextView) childView.findViewById(R.id. tv_key);valueTv = (TextView) childView.findViewById(R.id. tv_value);keyTv.setText(rowItemList.get(i).getKey());valueTv.setText(rowItemList.get(i).getValue());contentLayout.addView(childView);}}}
6.最后创建Activity-----AutoLayoutActivity.class
public class AutoLayoutActivity extends Activity {private LinearLayout contentLl;private List<RowItem> mList;@Overrideprotected void onCreate(Bundle savedInstanceState) {super.onCreate(savedInstanceState);setContentView(R.layout. activity_common_info);contentLl = (LinearLayout) findViewById(R.id. ll_content);mList = new ArrayList<RowItem>();mList.add( new RowItem( "姓名", "张三"));mList.add( new RowItem( "性别", "男"));mList.add( new RowItem( "年龄", "28"));mList.add( new RowItem( "学历", "博士"));CreateViewUtil. createContentView( this, contentLl, mList);}}
释疑：
大家或许会问，就"姓名"，"性别"几行而已直接在布局文件中写死不是更快，为什么弄得这么麻烦。
这样做的目的是当项目中有大量这种类似的页面时，这种方式方便快捷，多个类似的Activity可以共用一个布局文件就可以，不需要写很长的布局文件，更不需要一个一个的找到控件把值设置进去。总之一句话，能少写一行代码就少写一行。
