Android ListView例子詳解

三種實現方法，由淺入深。這中間要注意Adapter的用法，其實你要是看過Android的文檔，你會發現有很多Adapter，

如果你還不太清楚適配器模式，可以先補補這方面的知識。在實際工作中，設計模式是個很好的幫手。

兩個layout文件：

main.xml

1. <?xml version="1.0" encoding="utf-8"?>
2. <LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
3. android:layout_width="fill_parent"
4. android:layout_height="fill_parent"
5. android:orientation="vertical" >
7. <TextView
8. android:layout_width="fill_parent"
9. android:layout_height="wrap_content"
10. android:text="@string/hello" />
12. <ListView
13. android:id="@+id/listview"
14. android:layout_width="match_parent"
15. android:layout_height="match_parent"
16. ></ListView>
18. </LinearLayout>

listview.xml

1. <?xml version="1.0" encoding="utf-8"?>
2. <LinearLayout
3. xmlns:android="http://schemas.android.com/apk/res/android"
4. android:id="@+id/linerlayout1"
5. android:orientation="vertical"
6. android:layout_height="fill_parent"
7. android:layout_width="fill_parent"
8. >
9. <TextView
10. android:id="@+id/person_name"
11. android:textSize="23sp"
12. android:layout_width="wrap_content"
13. android:layout_height="wrap_content"
14. />
15. <TextView
16. android:id="@+id/person_age"
17. android:layout_width="wrap_content"
18. android:layout_height="wrap_content"
19. />
20. <TextView
21. android:id="@+id/person_email"
22. android:layout_width="wrap_content"
23. android:layout_height="wrap_content"
24. />
25. <TextView
26. android:id="@+id/person_address"
27. android:layout_width="wrap_content"
28. android:layout_height="wrap_content"
29. />
30. </LinearLayout>

1. package com.linc.listview;
3. import android.app.Activity;
4. import android.os.Bundle;
5. import android.widget.ArrayAdapter;
6. import android.widget.ListView;
8. public class LincListViewActivity extends Activity {
9. private final static String[] data = {"張飛","張遼","張角","張三豐","張牙舞爪","張燈結彩","張唑啉","張大民"};
11. //創建數據源.
12. Zhang[] data2 = new Zhang[]{
13. new Zhang("張飛",38,"[email protected]","燕山"),
14. new Zhang("張遼",36,"[email protected]","雁門"),
15. new Zhang("張角",51,"[email protected]","钜鹿"),

22. };
23. /** Called when the activity is first created. */
24. @Override
25. public void onCreate(Bundle savedInstanceState) {

27. setContentView(R.layout.main);
29. ListView listview = (ListView)findViewById(R.id.listview);
30. /*
31. * 第一種：普通字符串
32. */
33. ArrayAdapter<String> adapter1 = new ArrayAdapter<String>(this,
34. android.R.layout.simple_list_item_1,data);
36. /*
37. * 第二種：文藝類對象
38. */
39. ArrayAdapter<Zhang> adapter2 = new ArrayAdapter<Zhang>(this,
40. android.R.layout.simple_list_item_1,data2);
42. /*
43. * 第三種：自定義適配器
44. */
45. ListAdapter adapter3 = new ListAdapter(this, R.layout.listview,data2) ;
47. listview.setAdapter(adapter3);
48. }
49. }
