炒沙作縻终不饱，缕冰文章费工巧。这篇文章主要讲述android读取通讯录相关的知识，希望能为你提供帮助。

第一步：注册权限

< uses-permission android:name="android.permission.WRITE_CONTACTS" />
< uses-permission android:name="android.permission.READ_CONTACTS" />

第二步：接收的model类

public class ContactModel { private String name; private ArrayList< String > list; public String getName() { return name; }public void setName(String name) { this.name = name; }public ArrayList< String> getList() { return list; }public void setList(ArrayList< String> list) { this.list = list; } }

第三步：mian——activity

public class MainActivity extends AppCompatActivity {private Button button; private ListView listView; static final String TAG = "MainActivity"; ArrayList< ContactModel> dataList = new ArrayList< ContactModel> (); @Override protected void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.activity_main); listView = (ListView)findViewById(R.id.contrcts_view); readContacts(); MainAdapter adapter = new MainAdapter(this,dataList); listView.setAdapter(adapter); }private void readContacts(){Cursor cursor = null; try { cursor = this.getContentResolver().query(ContactsContract.Contacts.CONTENT_URI, null, null, null, null); int contactIdIndex = 0; int nameIndex = 0; if(cursor.getCount() > 0) { contactIdIndex = cursor.getColumnIndex(ContactsContract.Contacts._ID); nameIndex = cursor.getColumnIndex(ContactsContract.Contacts.DISPLAY_NAME); }ContactModel model = null; while(cursor.moveToNext()) {model = new ContactModel(); String contactId = cursor.getString(contactIdIndex); String name = cursor.getString(nameIndex); //Log.i(TAG, contactId); Log.i(TAG, "==============:" + name); model.setName(name); /* * 查找该联系人的phone信息 */ Cursor phones = this.getContentResolver().query(ContactsContract.CommonDataKinds.Phone.CONTENT_URI, null, ContactsContract.CommonDataKinds.Phone.CONTACT_ID + "=" + contactId, null, null); int phoneIndex = 0; if (phones.getCount() > 0) { phoneIndex = phones.getColumnIndex(ContactsContract.CommonDataKinds.Phone.NUMBER); } ArrayList < String> list = new ArrayList< String> (); while (phones.moveToNext()) {String phoneNumber = phones.getString(phoneIndex); Log.i(TAG, "==============:" + phoneNumber); list.add(phoneNumber); }model.setList(list); dataList.add(model); }}catch (Exception e){ Log.e(TAG,e.toString()); }finally { if(cursor != null){ cursor.close(); } }}}

第四步：adapter

public class MainAdapter extends BaseAdapter {private Context context; private List< ContactModel> list; public MainAdapter(Context context, List< ContactModel> list){ this.context = context; this.list = list; }@Override public int getCount() { return this.list.size(); }@Override public Object getItem(int i) { return this.list.get(i); }@Override public long getItemId(int i) { return i; }@Override public View getView(int i, View view, ViewGroup viewGroup) {ViewHolder holder; if(view == null){ view = LayoutInflater.from(this.context).inflate(R.layout.item_main,null); holder = new ViewHolder(); holder.nameTV = (TextView)view.findViewById(R.id.name); holder.phoneTV = (TextView)view.findViewById(R.id.phone); view.setTag(holder); }else{ holder = (ViewHolder)view.getTag(); }ContactModel model = this.list.get(i); holder.nameTV.setText(model.getName()); StringBuffer buffer = new StringBuffer(); for (int j=0; j< model.getList().size(); j++){ if(j==0){ buffer.append(model.getList().get(j)); }else { buffer.append("\\n"+model.getList().get(j)); } } holder.phoneTV.setText(buffer.toString()); return view; }classViewHolder{ TextView nameTV; TextView phoneTV; } }

第五步：item 布局

< ?xml version="1.0" encoding="utf-8"?> < LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" android:layout_width="match_parent" android:layout_height="wrap_content" android:orientation="vertical"> < TextView android:layout_width="match_parent" android:layout_height="wrap_content" android:text="tom" android:layout_margin="5dp" android:id="@+id/name"/> < TextView android:layout_width="match_parent" android:layout_height="wrap_content" android:text="18580633453" android:layout_margin="5dp" android:id="@+id/phone"/> < View android:layout_width="match_parent" android:layout_height="1dp" android:background="#d6d6d6" /> < /LinearLayout>

main的布局就一个listview，如果不会的话我需要静静了

2.系统通讯录这里是使用fragement做的，要用startActivityForResult

textView.setOnClickListener(new View.OnClickListener() { @Override public void onClick(View view) { Intent intent = new Intent(Intent.ACTION_PICK, ContactsContract.Contacts.CONTENT_URI); startActivityForResult(intent, 1); } }); @Override public void onActivityResult(int requestCode, int resultCode, Intent data) { super.onActivityResult(requestCode, resultCode, data); if (resultCode == Activity.RESULT_OK) {// ContentProvider展示数据类似一个单个数据库表 // ContentResolver实例带的方法可实现找到指定的ContentProvider并获取到ContentProvider的数据 ContentResolver reContentResolverol = getActivity(). getContentResolver(); // URI,每个ContentProvider定义一个唯一的公开的URI,用于指定到它的数据集 Uri contactData = https://www.songbingjia.com/android/data.getData(); // 查询就是输入URI等参数,其中URI是必须的,其他是可选的,如果系统能找到URI对应的ContentProvider将返回一个Cursor对象. Cursor cursor = getActivity().managedQuery(contactData, null, null, null, null); cursor.moveToFirst(); // 获得DATA表中的名字 username = cursor.getString(cursor .getColumnIndex(ContactsContract.Contacts.DISPLAY_NAME)); // 条件为联系人ID String contactId = cursor.getString(cursor .getColumnIndex(ContactsContract.Contacts._ID)); // 获得DATA表中的电话号码，条件为联系人ID,因为手机号码可能会有多个 Cursor phone = reContentResolverol.query( ContactsContract.CommonDataKinds.Phone.CONTENT_URI, null, ContactsContract.CommonDataKinds.Phone.CONTACT_ID +" = " + contactId, null, null); while (phone.moveToNext()) { usernumber = phone .getString(phone .getColumnIndex(ContactsContract.CommonDataKinds.Phone.NUMBER)); //et_mobile.setText(usernumber + " (" + username + ")"); toastShowShort(usernumber + " (" + username + ")"); }} }
