Android学习之一：通讯录
来源：互联网 发布：口风琴基础教程软件 编辑：程序博客网 时间：2024/06/11 18:41
自己练手的一个小程序。
有如下功能：
1.读取系统联系人信息，将联系人姓名、号码、邮箱和头像读取出来，显示到界面上。
2.对系统联系人信息进行增删改查。
3.可以调用系统的拨号功能，进行拨打电话的操作。
4.通过一个免费的查询号码归属地的api接口，可以对某个号码的归属地进行查询。
非常简单的一个小程序。但是因为新手，各种不熟悉，所以过程还是有点艰辛，遇到了好多bug。
得到的：
在这个过程中，对于ContentProvider有了更深的了解。尤其是可以通过一个Uri获取到联系人的所有信息，这个学到了。
对HttpConnection和JSON格式的解析也有了更深的了解。
不足的：
联系人头像，本程序中可以通过拍照然后裁剪、从相册选取照片然后裁剪，设置到ImageView上。对这里尤其不熟，查了很多资料。但是仍旧不成功。在论坛上问人，终于知道魅族手机的照片裁剪跟别的手机不一样。好心塞。
遗憾：
系统联系人姓名展示在listview中，应该是进行首字母排序的。我在网上搜了搜，中文首字母排序有点麻烦。以后再增加这个功能吧。
吶，不管过程怎么样，最后做出来还是挺开心的。
贴代码吧：
首先是展示系统所有的联系人
public class Contacts extends Activity implements View.OnClickListener,AdapterView.OnItemClickListener{ /** * uri * */ public static final Uri ContactsUri = ContactsContract.Contacts.CONTENT_URI; public final String ID = ContactsContract.Contacts._ID; public final String NAME = ContactsContract.Contacts.DISPLAY_NAME; /** * serch标识 * */ public static boolean FROM_SERCH = false; /** * contentresover对象 * */ public ContentResolver contentResolver; /** * 控件初始化 * */ public ListView listView; public EditText input; public Button serch; /** * 数据源初始化 * */ public List<String> contactsList; /** * 适配器初始化 * */ public ArrayAdapter<String> adapter; @Override protected void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.activity_contacts); //控件初始化和监听事件 init(); //读取系统联系人，存储到contactsList 中 contactsList = new ArrayList<String>(); readContacts(); //视图加载适配器 adapter = new ArrayAdapter<String>(this, android.R.layout.simple_list_item_1, contactsList); listView.setAdapter(adapter); } /** * 复写onresume方法，当本页面重新获取焦点时，刷新listview内容 * */ @Override protected void onResume() { super.onResume(); //从数据库中重新获取所有的联系人名字，然后listview更新 contactsList.clear();//先清除list集合中原有的联系人name，然后重新获取，否则会重复加载多个联系人的name readContacts(); adapter = null; adapter = new ArrayAdapter<String>(this, android.R.layout.simple_list_item_1, contactsList); listView.setAdapter(adapter); } /** * 控件初始化 * */ public void init(){ listView = (ListView) findViewById(R.id.listview); input = (EditText) findViewById(R.id.serch); serch = (Button) findViewById(R.id.bt_serch); //点击事件 serch.setOnClickListener(this); listView.setOnItemClickListener(this); } /** * 获取联系人名字 * */ public void readContacts(){ //获取contentResolver对象 contentResolver = getContentResolver(); //查询联系人id和名字 Cursor cursor = contentResolver.query(ContactsUri,null,null,null,null); while (cursor.moveToNext()){ String id = cursor.getString(cursor.getColumnIndex(ID)); Log.i("test",id); String name = cursor.getString(cursor.getColumnIndex(NAME)); Log.i("test", name); //联系人名字加入list集合中， contactsList.add(name); } if (cursor != null){ cursor.close(); } } @Override public void onClick(View v) { switch (v.getId()){ case R.id.bt_serch: String serchName = input.getText().toString(); Log.i("test",serchName); List<String> serchNameList = new ArrayList<String>(); //在contactsList中进行匹配，看是否有这个名字，如果有，每查到一个人，就存储到contactsList中。 for(int i = 0;i<contactsList.size();i++){ String name = contactsList.get(i); if(name.contains(serchName)){ serchNameList.add(name); } } //更新listview adapter = null; adapter = new ArrayAdapter<String>(Contacts.this,android.R.layout.simple_list_item_1,serchNameList); listView.setAdapter(adapter); input.setText(""); Log.i("test", "contactsList内容更新"); FROM_SERCH = true; break; } } @Override public void onItemClick(AdapterView<?> parent, View view, int position, long id) { String personName = contactsList.get(position); String personID = null; //根据name查找contacts中的id，将id发送过去 contentResolver = getContentResolver(); Cursor cursorId = contentResolver.query(ContactsContract.Contacts.CONTENT_URI, null, ContactsContract.Contacts.DISPLAY_NAME +"=?", new String[]{personName}, null); while (cursorId.moveToNext()){ personID = cursorId.getString(cursorId.getColumnIndex(ContactsContract.Contacts._ID)); } Log.i("test",personID);// 弹出联系人详情页面 Intent contactIntent = new Intent(Contacts.this,OneContact.class); contactIntent.putExtra("person_id",personID); startActivity(contactIntent); Log.i("test","下一个页面"); } /** * 复写back键 * */ @Override public void onBackPressed() { if (FROM_SERCH == true){ adapter = null; adapter = new ArrayAdapter<String>(this, android.R.layout.simple_list_item_1, contactsList); listView.setAdapter(adapter); FROM_SERCH = false; }else { finish(); } }}然后是某个联系人的详细信息界面：

/** * Created by lee on 2016/10/25. */public class LocationActivity extends Activity{ /** * 初始化控件 * */ private TextView province, city, supplier, suit; private Button query; private EditText phoneNumber; /** * handler * */ private android.os.Handler handler = new android.os.Handler(){ public void handleMessage(Message message){ String[] result = (String[])message.obj; String supplierName = result[0]; String provinceName = result[1]; String cityName = result[2]; String suitName = result[3]; //更新ui province.setText(provinceName); city.setText(cityName); supplier.setText(supplierName); suit.setText(suitName); } }; @Override protected void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); // requestWindowFeature(Window.FEATURE_NO_TITLE); setContentView(R.layout.activity_phone_number); province = (TextView) findViewById(R.id.province); city = (TextView)findViewById(R.id.city); supplier = (TextView)findViewById(R.id.supplier); suit = (TextView)findViewById(R.id.suit); query = (Button)findViewById(R.id.query); phoneNumber = (EditText)findViewById(R.id.phone_number); /** * 手机号码 * */ final String number = getIntent().getStringExtra("number"); /** * 显示归属地 * */ phoneNumber.setText(number); queryPhoneNumberLocation(number); /** * 点击之后查询 * */ query.setOnClickListener(new View.OnClickListener() { @Override public void onClick(View v) { String number = String.valueOf(phoneNumber.getText()); queryPhoneNumberLocation(number); } }); } public void queryPhoneNumberLocation(String number){ String address = "http://apis.baidu.com/apistore/mobilenumber/mobilenumber?phone="; if (number.length()==11){ HttpRequest.httpRequest(address + number, new HttpCallBackListener() { @Override public void onFinish(String response) { String[] result = new MyUtil().handleJSON(response); Message message = new Message(); message.obj = result; handler.sendMessage(message); } @Override public void onError(Exception e) { runOnUiThread(new Runnable() { @Override public void run() { Toast.makeText(LocationActivity.this, "查询失败", Toast.LENGTH_SHORT).show(); } }); } }); }else{ province.setText("请输入正确的手机号码！"); city.setText(""); supplier.setText(""); suit.setText(""); } }}然后是HttpConnection，连接服务器，获取某个号码的归属地
/** * Created by lee on 2016/10/25. */public class HttpRequest { public static void httpRequest(final String address, final HttpCallBackListener listener){ new Thread(new Runnable() { @Override public void run() { URL url; HttpURLConnection connection = null; try { url = new URL(address); connection = (HttpURLConnection) url.openConnection(); connection.setRequestMethod("GET"); connection.setRequestProperty("apikey", "a7146a37e0da2251ab00d9ea7c64cd66"); connection.setConnectTimeout(8000); connection.setReadTimeout(8000); InputStream inputStream = connection.getInputStream(); BufferedReader bufferedReader = new BufferedReader(new InputStreamReader(inputStream)); String line = null; StringBuilder response = new StringBuilder(); while((line = bufferedReader.readLine())!=null){ response.append(line); } if (listener != null){ listener.onFinish(response.toString()); } } catch (Exception e) { if (listener!=null){ listener.onError(e); } } finally { connection.disconnect(); } } }).start(); }}然后是HttpCallBackListener接口，回调机制
public interface HttpCallBackListener { public void onFinish(String response); public void onError(Exception e);}然后是工具类，对服务器返回的json数据进行解析

<?xml version="1.0" encoding="utf-8"?><LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" android:layout_height="match_parent" android:layout_width="match_parent" android:orientation="vertical"> <EditText android:id="@+id/phone_number" android:layout_width="match_parent" android:layout_height="wrap_content" android:hint="请输入要查询的手机号" android:textSize="24sp"/> <Button android:id="@+id/query" android:layout_width="wrap_content" android:layout_height="wrap_content" android:layout_gravity="center_horizontal" android:text="查询" android:textSize="24sp"/> <TextView android:id="@+id/province" android:layout_width="wrap_content" android:layout_height="wrap_content" android:textSize="24sp"/> <TextView android:id="@+id/city" android:layout_width="wrap_content" android:layout_height="wrap_content" android:textSize="24sp"/> <TextView android:id="@+id/supplier" android:layout_width="wrap_content" android:layout_height="wrap_content" android:textSize="24sp"/> <TextView android:id="@+id/suit" android:layout_width="wrap_content" android:layout_height="wrap_content" android:textSize="24sp"/></LinearLayout>最后是各种权限
