如何读取系统联系人姓名和电话号码（1）

定义一个点击事件，点击后进入系统联系人界面选择

//跳转到联系人页面private void contactRead() {// Intent intent=new Intent(Intent.ACTION_GET_CONTENT);// intent.setType("vnd.android.cursor.item/phone");Intent intent = new Intent(Intent.ACTION_PICK,ContactsContract.CommonDataKinds.Phone.CONTENT_URI);startActivityForResult(intent, 0);}

对返回的结果进行处理

@Overrideprotected void onActivityResult(int requestCode, int resultCode, Intent data) {switch (requestCode) {case 0:switch (resultCode) {case Activity.RESULT_OK:Uri uri = data.getData();// 查看联系人信息// Cursor cursor=managedQuery(uri, null, null, null,// null);//和下边的结果一样，唯一区别可以用activity管理cursor的生命周期；Cursor cursor = getContentResolver().query(uri, null, null,null, null);// 根据返回的uri获取电话号码cursor.moveToFirst();String num = cursor.getString(cursor.getColumnIndexOrThrow(ContactsContract.CommonDataKinds.Phone.NUMBER));etnumber.setText(num);// 获取外键idString contact_id = cursor.getString(cursor.getColumnIndexOrThrow(ContactsContract.CommonDataKinds.Phone.CONTACT_ID));// 根据外键id获取姓名Cursor namecursor = getContentResolver().query(ContactsContract.Contacts.CONTENT_URI, null,ContactsContract.Contacts._ID + "=" + contact_id, null,null);namecursor.moveToNext();String name = namecursor.getString(namecursor.getColumnIndexOrThrow(ContactsContract.Contacts.DISPLAY_NAME));etname.setText(name);namecursor.close();cursor.close();break;}break;}super.onActivityResult(requestCode, resultCode, data);}
