Question

所以我使用this tutorial创建了一个简单的启动器。我创建了一些空按钮，我打算用它们在按下时立即拨号。

默认情况下，按钮没有指定的编号。我希望按钮在第一次按下时启动默认联系人应用程序窗口，因此用户可以选择要分配给该按钮的联系人号码。然后我会通过意图启动它。

我不知道如何完成这项工作的第一部分（打开联系人应用程序，然后为按钮分配详细信息）。我该如何工作？

如果我从核心理解你的问题，你需要开始一个活动来获得结果。您可以通过单击按钮然后onActivityResult - ＆gt;开始您的活动（联系人应用）。你得到你想要的数据。

例如：

private static final int REQUEST_CONTACT = 1;
private static final int RESULT_OK = -1;
private static final int RESULT_CANCELED = 0;
private Uri mInfo;
private Context mContext;

 Button startContactsApp = (Button)findViewByid(...);
        startContactsApp.setOnClickListener(new View.OnClickListener() {
                @Override
                public void onClick(View v) {
               new Thread(new Runnable() { // you need a thread because this operation takes plenty of time
                @Override
                public void run() {
                  Intent contactIntent = new Intent(Intent.ACTION_PICK, ContactsContract.Contacts.CONTENT_URI);
                  contactIntent.setType(ContactsContract.CommonDataKinds.Phone.CONTENT_TYPE); // to display contacts who have phone number
                  startActivityForResult(contactIntent, REQUEST_CONTACT);
                  }
         }).start();
       }
    });

结果：

 @Override
public void onActivityResult(int requestCode, int resultCode, Intent data) {
    if(requestCode == REQUEST_CONTACT){
        if(resultCode == RESULT_OK && data != null){
            mInfo = data.getData();
            String name = getContactNameAgenda();   // the name you need
            String phone = getContactPhoneNumberAgenda();  //the number you need
            Toast.makeText(mContext,"CONTACT ADDED !",Toast.LENGTH_SHORT).show();
        }
        else if (resultCode == RESULT_CANCELED){
            Toast.makeText(getActivity(),"CANCELLED OR SOME ERROR OCCURRED !",Toast.LENGTH_SHORT).show();
        }
    }

在这里，您将获得所选联系人的姓名和电话号码：

private String getContactNameAgenda(){
    Cursor cursor = mContext.getContentResolver().query(mInfo, null,
            null, null, null);

    cursor.moveToFirst();
    String name = cursor.getString(cursor.getColumnIndex(ContactsContract.Contacts.DISPLAY_NAME));
    cursor.close();
    return name;
}

private String getContactPhoneNumberAgenda(){
    Cursor cursor = mContext.getContentResolver().query(mInfo, new String[]{ContactsContract.Contacts._ID},
            null, null, null);
    cursor.moveToFirst();
    String id = cursor.getString(cursor.getColumnIndex(ContactsContract.Contacts._ID));
    cursor.close();

    // Using the contact ID now we will get contact phone number
    Cursor cursorPhone = mContext.getContentResolver().query(ContactsContract.CommonDataKinds.Phone.CONTENT_URI,
            new String[]{ContactsContract.CommonDataKinds.Phone.NUMBER},

            ContactsContract.CommonDataKinds.Phone._ID + " = ? AND " +  // Phone._ID is for the database ; Phone.CONTACT_ID is for contact when you are not querying that table
                    ContactsContract.CommonDataKinds.Phone.TYPE + " = " +
                    ContactsContract.CommonDataKinds.Phone.TYPE_MOBILE,
            new String[]{id},
            null);

    cursorPhone.moveToFirst();
    String number = cursorPhone.getString(cursorPhone.getColumnIndex(ContactsContract.CommonDataKinds.Phone.NUMBER));
    cursorPhone.close();
    return number;
}

我希望这会对你有所帮助。
