android利用ContentResolver访问者获取手机联系人信息

转载自：http://www.jb51.net/article/106379.htm

首先需要在AndroidManifest.xml文件中添加权限：

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

activity_main.xml布局：

 <LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"

    xmlns:tools="http://schemas.android.com/tools"

    android:id="@+id/activity_main"

    android:layout_width="match_parent"

    android:layout_height="match_parent"

    android:orientation="vertical"

    tools:context="com.example.android_25.MainActivity">

    <ListView

      android:layout_width="wrap_content"

      android:layout_height="wrap_content"

      android:id="@+id/lv_lxr"

      >

    </ListView>

  </LinearLayout>

activity_xs.xml布局：

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"

    xmlns:tools="http://schemas.android.com/tools"

    android:id="@+id/activity_xs"

    android:layout_width="match_parent"

    android:layout_height="match_parent"

    android:orientation="vertical"

    tools:context="com.example.android_25.XsActivity">

  <TextView

      android:layout_width="match_parent"

      android:layout_height="wrap_content"

      android:id="@+id/tv_name"

    />

    <TextView

      android:layout_width="match_parent"

      android:layout_height="wrap_content"

      android:id="@+id/tv_telephone"

    />

  </LinearLayout>

MainActivity类：

private ListView lv_lxr;

private Button b_name;

private ContentResolver cr;

private List<Map<String, Object>> datalistView;

@Override

protected void onCreate(Bundle savedInstanceState) {

  super.onCreate(savedInstanceState);

  setContentView(R.layout.activity_main);

  //获得ListView

  lv_lxr = (ListView) findViewById(R.id.lv_lxr);

  //得到访问者

  cr = getContentResolver();

  //定义一个接收联系人姓名和电话号码的集合

  datalistView = new ArrayList<>();

      Uri uri=Uri.parse("content://com.android.contacts/raw_contacts");

      Cursor cursor= cr.query(uri,null,null,null,null);

      while(cursor.moveToNext()){

        int id=cursor.getInt(cursor.getColumnIndex("_id"));

        Uri uriData=Uri.parse("content://com.android.contacts/raw_contacts/"+id+"/data");

        Cursor contactData= cr.query(uriData,null,null,null,null);

        //用来装姓名

        String aa="";

        //用来装号码

        String bb="";

        while(contactData.moveToNext()){

          String type=contactData.getString(contactData.getColumnIndex("mimetype"));

          //如果获取的是vnd.android.cursor.item/phone_v2则是号码

          if(type.equals("vnd.android.cursor.item/phone_v2")){

            bb=contactData.getString(contactData.getColumnIndex("data1"));

            //如果获取的是vnd.android.cursor.item/name则是姓名

          }else if(type.equals("vnd.android.cursor.item/name")) {

            aa=contactData.getString(contactData.getColumnIndex("data1"));

          }

        }

        //将用户名和号码放入Map集合中

        Map<String,Object> map=new HashMap<>();

        map.put("images",aa);

        map.put("titles",bb);

        datalistView.add(map);

      }

  SimpleAdapter adapter=new SimpleAdapter(this, datalistView,R.layout.activity_xs,new String[]{"images","titles"},new int[]{R.id.tv_name,R.id.tv_telephone});

  lv_lxr.setAdapter(adapter);

}

第二种：通过Butten按钮跳转到系统的手机联系人界面，单个获取手机联系人信息，展示在ListView中

activity_contacts.xml布局:

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"

      xmlns:tools="http://schemas.android.com/tools"

      android:id="@+id/activity_contacts"

      android:layout_width="match_parent"

      android:layout_height="match_parent"

      android:orientation="vertical"

      tools:context="com.example.android_25.ContactsActivity">

    <LinearLayout

      android:layout_width="match_parent"

      android:layout_height="wrap_content">

        <Button

          android:layout_width="wrap_content"

          android:layout_height="wrap_content"

          android:text="跳转到联系人页面"

          android:id="@+id/b_tzcontacts"

          />

    </LinearLayout>

    <ListView

      android:layout_width="wrap_content"

      android:layout_height="wrap_content"

        android:id="@+id/lv_contacts"

      ></ListView>

</LinearLayout>

ContactsActivity类：

private Button b_tzcontacts;

private String phoneName;

private String phoneNumber;

private List<Map<String,Object>> datalistView;

private ListView lv_contacts;

private SimpleAdapter adapter;

@Override

protected void onCreate(Bundle savedInstanceState) {

  super.onCreate(savedInstanceState);

  setContentView(R.layout.activity_contacts);

  //获得跳转到联系人的id

  b_tzcontacts =(Button) findViewById(R.id.b_tzcontacts);

  //获得ListView的ID

  lv_contacts =(ListView) findViewById(R.id.lv_contacts);

  //定义一个接受联系人姓名和电话号码的集合

  datalistView = new ArrayList<>();

  //获取联系人的点击事件

  b_tzcontacts.setOnClickListener(new View.OnClickListener() {

    @Override

    public void onClick(View view) {

      Intent intentPhone=new Intent(Intent.ACTION_PICK);

      intentPhone.setData(ContactsContract.Contacts.CONTENT_URI);

      startActivityForResult(intentPhone,0);

    }

  });

  //R.layout.activity_xs就是上文的activity_xs布局问价

  adapter = new SimpleAdapter(this, datalistView, R.layout.activity_xs,new String[]{"images","titles"},new int[]{R.id.tv_name,R.id.tv_telephone});

  lv_contacts.setAdapter(adapter);

}

  //获得返回的结果

@Override

protected void onActivityResult(int requestCode, int resultCode, Intent data) {

  super.onActivityResult(requestCode, resultCode, data);

  switch (requestCode){

    case 0:

      if(resultCode== Activity.RESULT_OK){

        Uri uri=data.getData();

        Cursor cursor=managedQuery(uri,null,null,null,null);

        cursor.moveToFirst();

        String contactid=cursor.getString(cursor.getColumnIndex(ContactsContract.Contacts._ID));

        //得到ContentResolver

        ContentResolver contentResolver=getContentResolver();

        Cursor phone=contentResolver.query(ContactsContract.CommonDataKinds.Phone.CONTENT_URI,null,ContactsContract.CommonDataKinds.Phone.CONTACT_ID+"="+contactid,null,null);

        while (phone.moveToNext()){

          //联系人

          phoneName =phone.getString(phone.getColumnIndex(ContactsContract.CommonDataKinds.Phone.DISPLAY_NAME));

          //手机号码

          phoneNumber =phone.getString(phone.getColumnIndex(ContactsContract.CommonDataKinds.Phone.NUMBER));

          //格式化手机号

          phoneNumber = phoneNumber.replace("-","");

          phoneNumber = phoneNumber.replace("","");

          //将用户名和号码放入Map集合中

          Map<String,Object> map=new HashMap<>();

          map.put("images",phoneName);

          map.put("titles",phoneNumber);

          datalistView.add(map);

        }

        //刷新适配器

        adapter.notifyDataSetChanged();

      }

      break;

  }

}
