Android 擷取手機連絡人執行個體代碼詳解_Android

我的風格，廢話不多說了，直接給大家貼代碼了。

具體代碼如下所示：

package com.org.demo.demo;import com.org.wangfeng.R;import android.app.Activity;import android.content.Intent;import android.os.Bundle;import android.util.Log;import android.view.View;import android.widget.Button;import android.widget.EditText;public class GetPhoneActivity extends Activity { private EditText editText; private Button button; @Override protected void onCreate(Bundle savedInstanceState) {  // TODO Auto-generated method stub  super.onCreate(savedInstanceState);  setContentView(R.layout.getphoneactivity);  editText = (EditText) findViewById(R.id.et_getphone);  button = (Button) findViewById(R.id.bb_getphone);  button.setOnClickListener(new View.OnClickListener() {   @Override   public void onClick(View arg0) {    // TODO Auto-generated method stub    Intent intent = new Intent(GetPhoneActivity.this,      ContactActivity.class);    startActivityForResult(intent, 1);   }  }); } @Override protected void onActivityResult(int requestCode, int resultCode, Intent data) {  // System.out.println("resultCode:" + resultCode);  // System.out.println("requestCode:" + requestCode);  Log.d("jiejie", "被調用了");  if (resultCode == Activity.RESULT_OK) {   String phone = data.getStringExtra("phone");   Log.d("jiejie", "_______________"+phone);   phone = phone.replaceAll("-", "").replaceAll(" ", "");// 替換-和空格   editText.setText(phone);// 把電話號碼設定給輸入框  }  super.onActivityResult(requestCode, resultCode, data); }}package com.org.demo.demo;import java.util.ArrayList;import java.util.HashMap;import com.org.wangfeng.R;import android.app.Activity;import android.content.Intent;import android.database.Cursor;import android.net.Uri;import android.os.Bundle;import android.view.View;import android.widget.AdapterView;import android.widget.ListView;import android.widget.SimpleAdapter;import android.widget.AdapterView.OnItemClickListener;import android.widget.TextView;public class ContactActivity extends Activity { private ListView lvList; private ArrayList<HashMap<String, String>> readContact; private TextView back; @Override protected void onCreate(Bundle savedInstanceState) {  super.onCreate(savedInstanceState);  setContentView(R.layout.activity_contact);  back =(TextView)findViewById(R.id.back);  back.setOnClickListener(new View.OnClickListener() {      @Override   public void onClick(View arg0) {    // TODO Auto-generated method stub    finish();   }  });  lvList = (ListView) findViewById(R.id.lv_list);  readContact = readContact();  // System.out.println(readContact);  lvList.setAdapter(new SimpleAdapter(this, readContact,    R.layout.contact_list_item, new String[] { "name", "phone" },    new int[] { R.id.tv_name, R.id.tv_phone }));  lvList.setOnItemClickListener(new OnItemClickListener() {   @Override   public void onItemClick(AdapterView<?> parent, View view,     int position, long id) {    String phone = readContact.get(position).get("phone");// 讀取當前item的電話號碼    Intent intent = new Intent();    intent.putExtra("phone", phone);    setResult(Activity.RESULT_OK, intent);// 將資料放在intent中返回給上一個頁面    finish();   }  }); } private ArrayList<HashMap<String, String>> readContact() {  // 首先,從raw_contacts中讀取連絡人的id("contact_id")  // 其次, 根據contact_id從data表中查詢出相應的電話號碼和連絡人名稱  // 然後,根據mimetype來區分哪個是連絡人,哪個是電話號碼  Uri rawContactsUri = Uri    .parse("content://com.android.contacts/raw_contacts");  Uri dataUri = Uri.parse("content://com.android.contacts/data");  ArrayList<HashMap<String, String>> list = new ArrayList<HashMap<String, String>>();  // 從raw_contacts中讀取連絡人的id("contact_id")  Cursor rawContactsCursor = getContentResolver().query(rawContactsUri,    new String[] { "contact_id" }, null, null, null);  if (rawContactsCursor != null) {   while (rawContactsCursor.moveToNext()) {    String contactId = rawContactsCursor.getString(0);    // System.out.println(contactId);    // 根據contact_id從data表中查詢出相應的電話號碼和連絡人名稱, 實際上查詢的是視圖view_data    Cursor dataCursor = getContentResolver().query(dataUri,      new String[] { "data1", "mimetype" }, "contact_id=?",      new String[] { contactId }, null);    if (dataCursor != null) {     HashMap<String, String> map = new HashMap<String, String>();     while (dataCursor.moveToNext()) {      String data1 = dataCursor.getString(0);      String mimetype = dataCursor.getString(1);      // System.out.println(contactId + ";" + data1 + ";"      // + mimetype);      if ("vnd.android.cursor.item/phone_v2".equals(mimetype)) {       map.put("phone", data1);      } else if ("vnd.android.cursor.item/name"        .equals(mimetype)) {       map.put("name", data1);      }     }     list.add(map);     dataCursor.close();    }   }   rawContactsCursor.close();  }  return list; }}

本段代碼到此結束，代碼比較簡單，並附有注釋，希望對大家學習android擷取手機連絡人相關知識有所協助。
