我正在尝试从通话记录中获取联系人。我可以使用以下代码从主要联系人获取联系电话:
public void getContacts(View view) {
Intent intentContact = new Intent(Intent.ACTION_PICK, ContactsContract.Contacts.CONTENT_URI);
startActivityForResult(intentContact, 0);
}
public void onActivityResult(int requestCode, int resultCode, Intent intent)
{
if (requestCode == 0)
{
try {
to.setText(getContactInfo(intent));
} catch(NullPointerException e) {
// Do nothing ;)
}
}
}
protected String getContactInfo(Intent intent)
{
String phoneNumber = to.getText().toString();
Cursor cursor = managedQuery(intent.getData(), null, null, null, null);
while (cursor.moveToNext())
{
String contactId = cursor.getString(cursor.getColumnIndex(ContactsContract.Contacts._ID));
String name = cursor.getString(cursor.getColumnIndexOrThrow(ContactsContract.Contacts.DISPLAY_NAME));
if(phoneNumber.endsWith(">"))
phoneNumber += ", "+name;
else
phoneNumber += name;
String hasPhone = cursor.getString(cursor.getColumnIndex(ContactsContract.Contacts.HAS_PHONE_NUMBER));
if ( hasPhone.equalsIgnoreCase("1"))
hasPhone = "true";
else
hasPhone = "false" ;
if (Boolean.parseBoolean(hasPhone))
{
Cursor phones = getContentResolver().query(ContactsContract.CommonDataKinds.Phone.CONTENT_URI, null,ContactsContract.CommonDataKinds.Phone.CONTACT_ID +" = "+ contactId,null, null);
while (phones.moveToNext())
{ phoneNumber = phoneNumber + " <" + phones.getString(phones.getColumnIndex(ContactsContract.CommonDataKinds.Phone.NUMBER))+">";
}
phones.close();
}
}
cursor.close();
return phoneNumber;
}
它的作用是，当我们单击“联系人”按钮时，它将打开一个包含所有联系人的列表，用户可以选择任何联系人，并且所选联系人将添加到“收件人”字段中。我想做完全相同的事情，但是我不想显示所有联系人，而是只显示最近使用过的那些(调用记录)进行选择的联系人。
如果您还可以告诉如何与组一起执行此操作，那也很好。
最佳答案
我使用自己的版本进行了此操作。我使用了一个对话框，并将光标移到了通话记录。这是函数:
public void getCallLog() {
String[] callLogFields = { android.provider.CallLog.Calls._ID,
android.provider.CallLog.Calls.NUMBER,
android.provider.CallLog.Calls.CACHED_NAME /* im not using the name but you can*/};
String viaOrder = android.provider.CallLog.Calls.DATE + " DESC";
String WHERE = android.provider.CallLog.Calls.NUMBER + " >0"; /*filter out private/unknown numbers */
final Cursor callLog_cursor = getActivity().getContentResolver().query(
android.provider.CallLog.Calls.CONTENT_URI, callLogFields,
WHERE, null, viaOrder);
AlertDialog.Builder myversionOfCallLog = new AlertDialog.Builder(
getActivity());
android.content.DialogInterface.OnClickListener listener = new DialogInterface.OnClickListener() {
public void onClick(DialogInterface dialogInterface, int item) {
callLog_cursor.moveToPosition(item);
Log.v("number", callLog_cursor.getString(callLog_cursor
.getColumnIndex(android.provider.CallLog.Calls.NUMBER)));
callLog_cursor.close();
}
};
myversionOfCallLog.setCursor(callLog_cursor, listener,
android.provider.CallLog.Calls.NUMBER);
myversionOfCallLog.setTitle("Choose from Call Log");
myversionOfCallLog.create().show();
}
