Android中实现ListView横向滑动
这是我做的一个查询列表的页面 列表部分实现了 ListView的横向滑动
ListView页面：
1 package com.test.querylist;
2
3 import java.util.ArrayList;
4 import java.util.HashMap;
5
6 import com.test.R;
7
8 import android.app.Activity;
9 import android.os.Bundle;
10 import android.view.Gravity;
11 import android.view.View;
12 import android.widget.Button;
13 import android.widget.EditText;
14 import android.widget.HorizontalScrollView;
15 import android.widget.LinearLayout;
16 import android.widget.ListView;
17 import android.widget.SimpleAdapter;
18 import android.widget.LinearLayout.LayoutParams;
19
20 public class QueryListActivity extends Activity {
21
22 private static String str1 = "str1";
23 private static String str2 = "str2";
24 private static String str3 = "str3";
25
26 @Override
27 public void onCreate(Bundle icicle) {
28 super.onCreate(icicle);
29 setContentView(generateContentView());
30 }
31
32 private View generateContentView(){
33 //主页面
34 LinearLayout layMain = createLayout(LinearLayout.VERTICAL);
35 layMain.setPadding(5, 0, 5, 0);
36 //查询部分
37 LinearLayout layQuery = createLayout(LinearLayout.HORIZONTAL);
38 layQuery.setPadding(0, 0, 0, 0);
39 layQuery.setGravity(Gravity.CENTER);
40 generateQuery(layQuery);
41
42 //列表部分
43 LinearLayout layList = createLayout(LinearLayout.VERTICAL);
44 layList.setPadding(0, 0, 0, 0);
45 generateList(layList);
46
47 layMain.addView(layQuery);
48 layMain.addView(layList);
49 return layMain;
50 }
51
52 /**
53 * 列表部分布局
54 * */
55 private void generateList(LinearLayout layList) {
56 HorizontalScrollView hsView = new HorizontalScrollView(this);
57 hsView.setLayoutParams(new LayoutParams(LayoutParams.FILL_PARENT, LayoutParams.WRAP_CONTENT));
58
59 LinearLayout lly = createLayout(LinearLayout.VERTICAL);
60 // TODO Auto-generated method stub
61 ArrayList<HashMap<String, Object>> myLists = new ArrayList<HashMap<String, Object>>();
62 for (int i = 0; i < 10; i++) {
63 HashMap<String, Object> myList = new HashMap<String, Object>();
64 myList.put(str1, "asd");
65 myList.put(str2, "姓名(" + (i+1) + ")");
66 myList.put(str3, (5 + i) + "");
67 myLists.add(myList);
68 }
69 SimpleAdapter saImageItems = new SimpleAdapter(this, myLists,// 数据来源
70 R.layout.testuser,// 每一个user xml 相当ListView的一个组件
71 new String[] { str1, str2, str3 },
72 // 分别对应view 的id
73 new int[] { R.id.test_id1, R.id.test_id2, R.id.test_id3 });
74 // 获取listview
75 ListView listQuery = new ListView(this);
76 listQuery.setAdapter(saImageItems);
77
78 lly.addView(listQuery);
79 hsView.addView(lly);
80 layList.addView(hsView);
81 }
82
83 /**
84 * 查询部分布局
85 * */
86 private void generateQuery(LinearLayout layQuery) {
87 // TODO Auto-generated method stub
88 EditText txtQuery = new EditText(this);
89
90 txtQuery.setLayoutParams(new LayoutParams(400, LayoutParams.WRAP_CONTENT));
91 txtQuery.setMinHeight(60);
92 txtQuery.setMaxHeight(120);
93
94 Button btnQuery = new Button(this);
95 btnQuery.setText(R.string.querylist_query);
96 btnQuery.setOnClickListener(new Button.OnClickListener(){
97 public void onClick(View v) {
98 // TODO 设置点击事件
99 }
100 });
101 layQuery.addView(txtQuery);
102 layQuery.addView(btnQuery);
103 }
104
105 private LinearLayout createLayout(int iOrientation) {
106 LinearLayout lay = new LinearLayout(this);
107 lay.setLayoutParams(new LayoutParams(LayoutParams.FILL_PARENT, LayoutParams.WRAP_CONTENT));
108 lay.setOrientation(iOrientation);
109 return lay;
110 }
111 }
ListView组件的XML:
1 <?xml version="1.0" encoding="utf-8"?>
2 <LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
3 android:layout_height="wrap_content" android:layout_width="fill_parent"
4 android:paddingBottom="5dip" android:paddingTop="5dip"
5 android:paddingLeft="5dip" android:paddingRight="5dip"
6 android:orientation="vertical">
7 <LinearLayout android:layout_height="wrap_content"
8 android:paddingLeft="6dip" android:paddingRight="6dip"
9 android:orientation="horizontal" android:layout_width="fill_parent"
10 android:gravity="center_vertical">
11 <TextView android:id="@+id/test_id1" android:gravity="center"
12 android:layout_height="wrap_content" android:layout_width="300"
13 android:layout_weight="1" android:layout_margin = "5dip">
14 </TextView>
15 <TextView android:id="@+id/test_id2" android:gravity="center"
16 android:layout_height="wrap_content" android:layout_width="300"
17 android:layout_weight="1" android:layout_margin = "5dip">
18 </TextView>
19 <TextView android:id="@+id/test_id3" android:gravity="center"
20 android:layout_height="wrap_content" android:layout_width="300"
21 android:layout_weight="1" android:layout_margin = "5dip">
22 </TextView>
23 </LinearLayout>
24 </LinearLayout>
