***先是跳转过去***

//点击选择通讯录
                    AlertDialog.Builder builder = new AlertDialog.Builder(act);
                    builder.setTitle("提示：").setMessage("确定从通讯录选择联系人？").setCancelable(true)
                            .setPositiveButton("是", new DialogInterface.OnClickListener() {
                                @Override
                                public void onClick(DialogInterface dialogInterface, int i) {
                                    dialogInterface.dismiss();
                                    startActivityForResult(new Intent(
                                            Intent.ACTION_PICK, ContactsContract.Contacts.CONTENT_URI), 0);
                                }
                            }).setNegativeButton("否", new DialogInterface.OnClickListener() {
                        @Override
                        public void onClick(DialogInterface dialogInterface, int i) {
                            dialogInterface.dismiss();
                        }
                    }).show();

***获取返回的数据，重写onActivityResult方法***

@Override
        protected void onActivityResult(int requestCode, int resultCode, Intent data) { super.onActivityResult(requestCode, resultCode, data); if (resultCode == Activity.RESULT_OK) { ContentResolver reContentResolverol = getContentResolver(); Uri contactData = data.getData(); @SuppressWarnings("deprecation") Cursor cursor = managedQuery(contactData, null, null, null, null); cursor.moveToFirst(); String username = cursor.getString(cursor.getColumnIndex(ContactsContract.Contacts.DISPLAY_NAME)); String contactId = cursor.getString(cursor.getColumnIndex(ContactsContract.Contacts._ID)); Cursor phone = reContentResolverol.query(ContactsContract.CommonDataKinds.Phone.CONTENT_URI, null, ContactsContract.CommonDataKinds.Phone.CONTACT_ID + " = " + contactId, null, null); while (phone.moveToNext()) { String usernumber = phone.getString(phone.getColumnIndex(ContactsContract.CommonDataKinds.Phone.NUMBER)); KLog.e(usernumber+" ("+username+")"); cInviteeUsername.setText(username); cInviteeTel.setText(usernumber); }
    
            }
        }
