ListView的SimpleAdapter有很好的擴(kuò)展性，可以定義各種不同的布局，可以放上圖片、Button、CheckBox等等，本文實(shí)現(xiàn)一個(gè)帶有前后圖標(biāo)的列表視圖：

列表中item的組成:

(R.id.img_pre)( R.id.text )(R.id.img)

首先定義用來(lái)顯示列表中item的layout文件list_item2.xml:

<?xml version="1.0" encoding="utf-8"?> <LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" android:orientation="horizontal" android:layout_width="fill_parent" android:layout_height="fill_parent" > <ImageView android:id="@+id/img_pre" android:layout_width="wrap_content" android:layout_height="wrap_content" android:layout_gravity="center_vertical" /> <TextView android:id="@+id/text" android:layout_width="fill_parent" android:layout_height="wrap_content" android:padding="10dp" android:textSize="16sp" android:textStyle="bold|italic" android:layout_weight="1" /> <LinearLayout android:orientation="horizontal" android:layout_width="fill_parent" android:layout_height="wrap_content" android:gravity="right" android:layout_weight="2" > <ImageView android:id="@+id/img" android:layout_width="wrap_content" android:layout_height="wrap_content" android:paddingRight="10dp" android:layout_gravity="center_vertical" /> </LinearLayout> </LinearLayout>

整個(gè)一行作為一個(gè)LinearLayout，

第一個(gè)圖片作為一個(gè)IamgeView，文本為T(mén)extView，第二個(gè)圖片為ImageView，

第二個(gè)ImageView再放到一個(gè)LinearLayout里面，并

通過(guò)android:gravity及android:layout_weight來(lái)調(diào)整顯示位置

下面是實(shí)現(xiàn)代碼:

public class HelloListView extends ListActivity { /** Called when the activity is first created. */ @Override public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); //setListAdapter(new ArrayAdapter<String>(this, R.layout.list_item, COUNTRIES)); //setListAdapter(new ArrayAdapter<String>(this, android.R.layout.simple_list_item_1, COUNTRIES)); setListAdapter(new SimpleAdapter(this, getData(), R.layout.list_item2, new String[]{"img_pre", "text", "img"}, new int[]{R.id.img_pre, R.id.text, R.id.img})); ListView lv = getListView(); //lv.setTextFilterEnabled(true); lv.setOnItemClickListener(new OnItemClickListener() { @Override public void onItemClick(AdapterView<?> parent, View view, int pos, long id) { Map<String, Object> item = (Map<String, Object>)parent.getItemAtPosition(pos); Toast.makeText(getApplicationContext(), (String)item.get("text"), Toast.LENGTH_SHORT).show(); } }); } private List<Map<String, Object>> getData() { List<Map<String, Object>> list = new ArrayList<Map<String, Object>>(); for(int i = 0; i < COUNTRIES.length; i++) { Map<String, Object> map = new HashMap<String, Object>(); map.put("text", COUNTRIES[i]); map.put("img", R.drawable.img); map.put("img_pre", R.drawable.img_pre); list.add(map); } return list; } static final String[] COUNTRIES = new String[] { "Afghanistan", "Albania", "Algeria", "American Samoa", "Andorra", "Angola", "Anguilla", "Antarctica", "Antigua and Barbuda", "Argentina", "Armenia", "Aruba", "Australia", "Austria", "Azerbaijan", "Bahrain", "Bangladesh", "Barbados", "Belarus", "Belgium", "Belize", "Benin", "Bermuda", "Bhutan", "Bolivia", "Bosnia and Herzegovina", "Botswana", "Bouvet Island", "Brazil", "British Indian Ocean Territory", "British Virgin Islands", "Brunei", "Bulgaria", "Burkina Faso", "Burundi", "Cote d'Ivoire", "Cambodia", "Cameroon", "Canada", "Cape Verde", "Cayman Islands", "Central African Republic", "Chad", "Chile", "China", "Christmas Island", "Cocos (Keeling) Islands", "Colombia", "Comoros", "Congo", "Cook Islands", "Costa Rica", "Croatia", "Cuba", "Cyprus", "Czech Republic", "Democratic Republic of the Congo", "Denmark", "Djibouti", "Dominica", "Dominican Republic", "East Timor", "Ecuador", "Egypt", "El Salvador", "Equatorial Guinea", "Eritrea", "Estonia", "Ethiopia", "Faeroe Islands", "Falkland Islands", "Fiji", "Finland", "Former Yugoslav Republic of Macedonia", "France", "French Guiana", "French Polynesia", "French Southern Territories", "Gabon", "Georgia", "Germany", "Ghana", "Gibraltar", "Greece", "Greenland", "Grenada", "Guadeloupe", "Guam", "Guatemala", "Guinea", "Guinea-Bissau", "Guyana", "Haiti", "Heard Island and McDonald Islands", "Honduras", "Hong Kong", "Hungary", "Iceland", "India", "Indonesia", "Iran", "Iraq", "Ireland", "Israel", "Italy", "Jamaica", "Japan", "Jordan", "Kazakhstan", "Kenya", "Kiribati", "Kuwait", "Kyrgyzstan", "Laos", "Latvia", "Lebanon", "Lesotho", "Liberia", "Libya", "Liechtenstein", "Lithuania", "Luxembourg", "Macau", "Madagascar", "Malawi", "Malaysia", "Maldives", "Mali", "Malta", "Marshall Islands", "Martinique", "Mauritania", "Mauritius", "Mayotte", "Mexico", "Micronesia", "Moldova", "Monaco", "Mongolia", "Montserrat", "Morocco", "Mozambique", "Myanmar", "Namibia", "Nauru", "Nepal", "Netherlands", "Netherlands Antilles", "New Caledonia", "New Zealand", "Nicaragua", "Niger", "Nigeria", "Niue", "Norfolk Island", "North Korea", "Northern Marianas", "Norway", "Oman", "Pakistan", "Palau", "Panama", "Papua New Guinea", "Paraguay", "Peru", "Philippines", "Pitcairn Islands", "Poland", "Portugal", "Puerto Rico", "Qatar", "Reunion", "Romania", "Russia", "Rwanda", "Sqo Tome and Principe", "Saint Helena", "Saint Kitts and Nevis", "Saint Lucia", "Saint Pierre and Miquelon", "Saint Vincent and the Grenadines", "Samoa", "San Marino", "Saudi Arabia", "Senegal", "Seychelles", "Sierra Leone", "Singapore", "Slovakia", "Slovenia", "Solomon Islands", "Somalia", "South Africa", "South Georgia and the South Sandwich Islands", "South Korea", "Spain", "Sri Lanka", "Sudan", "Suriname", "Svalbard and Jan Mayen", "Swaziland", "Sweden", "Switzerland", "Syria", "Taiwan", "Tajikistan", "Tanzania", "Thailand", "The Bahamas", "The Gambia", "Togo", "Tokelau", "Tonga", "Trinidad and Tobago", "Tunisia", "Turkey", "Turkmenistan", "Turks and Caicos Islands", "Tuvalu", "Virgin Islands", "Uganda", "Ukraine", "United Arab Emirates", "United Kingdom", "United States", "United States Minor Outlying Islands", "Uruguay", "Uzbekistan", "Vanuatu", "Vatican City", "Venezuela", "Vietnam", "Wallis and Futuna", "Western Sahara", "Yemen", "Yugoslavia", "Zambia", "Zimbabwe" }; }

采用SimpleAdapter適配器，并添加了Click監(jiān)聽(tīng)，Click的時(shí)候顯示Toast提示信息

for(int i = 0; i < COUNTRIES.length; i++) { Map<String, Object> map = new HashMap<String, Object>(); map.put("text", COUNTRIES[i]); map.put("img", R.drawable.img); map.put("img_pre", R.drawable.img_pre); list.add(map); }

用來(lái)生成item數(shù)據(jù)

res/drawable 目錄中放入兩個(gè)img文件
