呼叫联系人，选择联系人发送短信，然后发送短信 [英] call contacts, choose contact to send sms to then send sms
问题描述
我期待调用用户的联系人列表。然后，他们会选择一个联系人发送短信到。我有一个很难理解如何发送短信时节省使用联系人。任何帮助将是AP preciated。这里是我的code所以下面为止。
包com.example.practiceapp;进口android.os.Bundle;
进口android.provider.ContactsContract;
进口android.app.Activity;
进口android.content.Intent;
进口android.view.Menu;
进口android.view.View;公共类扩展元{活动 @覆盖
公共无效的onCreate（捆绑savedInstanceState）{
super.onCreate（savedInstanceState）;
的setContentView（R.layout.activity_dollar）;
} // @覆盖
//公共布尔onCreateOptionsMenu（菜单菜单）{
//getMenuInflater().inflate(R.menu.activity_dollar，菜单）;
//返回true;
//} 公共无效的联系人（查看视图）{
意向意图=新意图（Intent.ACTION_PICK，ContactsContract.Contacts.CONTENT_URI）;
INT PICK_CONTACT = 0;
startActivityForResult（意向，PICK_CONTACT）;}
}
据presents工作示例选择一个电子邮件地址。
关键code，使用联系人选取器获得接触式ID后，是这样的：
//一切电子邮件查询
光标= getContentResolver（）查询（
Email.CONTENT_URI，空，
Email.CONTACT_ID +=？，
新的String [] {ID}，NULL）;
其中， ID 是接触式ID从联系人选择器返回（在教程解释）。拿到手机的数据，您将需要此更改为：
//的一切电话查询
光标= getContentResolver（）查询（
Phone.CONTENT_URI，空，
Phone.CONTACT_ID +=？，
新的String [] {ID}，NULL）;
请注意，联系人可以有多个电话号码，所以你必须建立一个第二个对话框，选择一个特定的电话号码。
的ArrayList＆LT;串GT; PHONENUMBERS =新的ArrayList＆LT;串GT;（）;
字符串名称=;
串号=;
INT nameIdx = cursor.getColumnIndex（Phone.DISPLAY_NAME）;
INT numberIdx = cursor.getColumnIndex（Phone.DATA）;
//获取所有电话号码的人
如果（cursor.getCount（）大于0）{
cursor.moveToFirst（）;
做{
名称= cursor.getString（nameIdx）; //从游标得到名称
数= cursor.getString（numberIdx）; //从游标获取电话号码
phoneNumbers.add（数）;
Log.v（DEBUG_TAG，得到的名字：+姓名+电话：
+号）;
}而（cursor.moveToNext（））;
showPhoneNumberSelectionDialog（姓名，PHONENUMBERS）;
}其他{
Log.w（DEBUG_TAG，无结果）;
}
（或者你可以调整光标从需要上述code读）
私人无效showPhoneNumberSelectionDialog（字符串名称，
最终的ArrayList＆LT;串GT;电话号码） {
1.建立一个AlertDialog来接从PHONENUMBERS（标题with'name'）的数字;
2.发送短信到该号码
}
构建警告对话框并不难，但涉及改造的ArrayList成String数组。见<一href=\"http://stackoverflow.com/questions/5374311/convert-arrayliststring-to-string/%22Convert%20ArrayList%3CString%3E%20to%20String%20%5B%5D%22\">Convert ArrayList中为String []
发送短信是相当容易的。有很多的例子在网络上。
这SO Q＆安培; A（如何在Android 2.0读接触）也是很好的背景，但最终我没有使用任何code如此。
I'm looking to call the users contacts list. They will then choose a contact to send an sms to. I'm having a hard time understanding how to save the contact for use when sending the sms. Any help would be appreciated. Here is my code so far below.
package com.example.practiceapp;
import android.os.Bundle;
import android.provider.ContactsContract;
import android.app.Activity;
import android.content.Intent;
import android.view.Menu;
import android.view.View;
public class Dollar extends Activity {
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_dollar);
}
//@Override
//public boolean onCreateOptionsMenu(Menu menu) {
//getMenuInflater().inflate(R.menu.activity_dollar, menu);
//return true;
//}
public void contacts(View view) {
Intent intent = new Intent(Intent.ACTION_PICK, ContactsContract.Contacts.CONTENT_URI);
int PICK_CONTACT=0;
startActivityForResult(intent, PICK_CONTACT);
}
}
I used Android Essentials: Using the Contact Picker
It presents a working example for selecting an email address.
The key code, after using the contact picker to get a contact ID, is this:
// query for everything email
cursor = getContentResolver().query(
Email.CONTENT_URI, null,
Email.CONTACT_ID + "=?",
new String[]{id}, null);
Where id is the contact ID returned from the Contacts picker (as explained in the tutorial). To get the phone data, you will need to change this to:
// query for everything phone
cursor = getContentResolver().query(
Phone.CONTENT_URI, null,
Phone.CONTACT_ID + "=?",
new String[]{id}, null);
Be aware that a contact can have multiple phone numbers, so you will have to build a second dialog to select a particular phone number.
ArrayList<String> phoneNumbers = new ArrayList<String>();
String name = "";
String number = "";
int nameIdx = cursor.getColumnIndex(Phone.DISPLAY_NAME);
int numberIdx = cursor.getColumnIndex(Phone.DATA);
// Get all phone numbers for the person
if (cursor.getCount() > 0) {
cursor.moveToFirst();
do {
name = cursor.getString(nameIdx); // get the name from the cursor
number = cursor.getString(numberIdx); // get the phone number from the cursor
phoneNumbers.add(number);
Log.v(DEBUG_TAG, "Got name: " + name + " phone: "
+ number);
} while (cursor.moveToNext());
showPhoneNumberSelectionDialog(name,phoneNumbers);
} else {
Log.w(DEBUG_TAG, "No results");
}
(or you can adapt the cursor reading from the above code as needed)
private void showPhoneNumberSelectionDialog(String name,
final ArrayList<String> phoneNumbers) {
1. Build an AlertDialog to pick a number from phoneNumbers (with'name' in the title);
2. Send an SMS to the number
}
Building the alert dialog is not hard, but involves transforming the ArrayList into a String array. See Convert ArrayList to String []
Sending the SMS is reasonably easy. There are plenty of examples on the web.
This SO Q&A (How to read contacts on Android 2.0) is also good background, but in the end I didn't use any code from it.
