ユーザーの連絡先リストに電話をかけたいと思っています。次に、SMSを送信する連絡先を選択します。SMSを送信するときに使用するために連絡先を保存する方法を理解するのに苦労しています。どんな助けでもいただければ幸いです。これが私のコードです。

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.
