    <p>I want to add my contacts from listview to contact page in android.. I am able to add contacts. But how do I avoid duplicates? </p> <p>For example: I have an entry with name Jony and number 123. If I press that same contact again it shouldn't be added to contact page. I dont want to add the contact if it is already in the contact page. How can I do this?</p> <p>Here is my code:</p> <pre><code>import_btn.setOnClickListener(new OnClickListener() { @Override public void onClick(View v) { // TODO Auto-generated method stub ArrayList&lt;HashMap&lt;String, String&gt;&gt; newArrayList=null; //ArrayList&lt;HashMap&lt;String, String&gt;&gt; selectedContact=null; ArrayList&lt;ContentProviderOperation&gt; ops = new ArrayList&lt;ContentProviderOperation&gt;(); newArrayList=ContactImportAdapter.contactsArrayList; for(int i=0;i&lt;newArrayList.size();i++) { String name; String number; String mail; name=newArrayList.get(i).get("import_viewContactName"); number=newArrayList.get(i).get("import_viewContactNumber"); mail=newArrayList.get(i).get("import_viewContactMail"); int rawContactInsertIndex = ops.size(); ops.add(ContentProviderOperation.newInsert(RawContacts.CONTENT_URI) .withValue(RawContacts.ACCOUNT_TYPE, null) .withValue(RawContacts.ACCOUNT_NAME, null).build()); ops.add(ContentProviderOperation .newInsert(Data.CONTENT_URI) .withValueBackReference(Data.RAW_CONTACT_ID,rawContactInsertIndex) .withValue(Data.MIMETYPE, StructuredName.CONTENT_ITEM_TYPE) .withValue(StructuredName.DISPLAY_NAME, name) // Name of the person .build()); ops.add(ContentProviderOperation .newInsert(Data.CONTENT_URI) .withValueBackReference( ContactsContract.Data.RAW_CONTACT_ID, rawContactInsertIndex) .withValue(Data.MIMETYPE, Phone.CONTENT_ITEM_TYPE) .withValue(Phone.NUMBER, number) // Number of the person .withValue(Phone.TYPE, Phone.TYPE_MOBILE).build()); ops.add(ContentProviderOperation.newInsert(ContactsContract.Data.CONTENT_URI) .withValueBackReference(ContactsContract.Data.RAW_CONTACT_ID, rawContactInsertIndex) .withValue(ContactsContract.Data.MIMETYPE, ContactsContract.CommonDataKinds.Email.CONTENT_ITEM_TYPE) .withValue(ContactsContract.CommonDataKinds.Email.DATA, mail) .withValue(ContactsContract.CommonDataKinds.Email.TYPE, ContactsContract.CommonDataKinds.Email.TYPE_WORK) .build()); //Toast.makeText(getApplicationContext(), "Contact Added Successfully", Toast.LENGTH_SHORT).show(); } newArrayList.clear(); try { ContentProviderResult[] res = getContentResolver().applyBatch(ContactsContract.AUTHORITY, ops); } catch (RemoteException e) { // error } catch (OperationApplicationException e) { // error } } }); </code></pre>

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
