我正在从我的应用程序中遇到一些不寻常的行为 - 我无法理解为什么，但是当用户从我的列表视图中选择一个联系人时，稍后从手机中检索到的联系人在某种程度上不是用户选择的... < / p>
更新了新代码，仍然无效。
public class nominateContactsActivity extends ListActivity {
public String strName;
public String strTelNo;
public static final String PREFS_NAME = "locationPrefs";
public static final ArrayList<NameValuePair> contactsArray = new ArrayList<NameValuePair>();
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
this.requestWindowFeature(Window.FEATURE_NO_TITLE);
setContentView(R.layout.nominatecontactsactivitytest);
this.getListView().setChoiceMode(ListView.CHOICE_MODE_MULTIPLE);
this.getListView().setChoiceMode(ListView.CHOICE_MODE_MULTIPLE);
//String[] projection = new String[] { ContactsContract.PhoneLookup.NUMBER};
String selection = ContactsContract.Contacts.HAS_PHONE_NUMBER + " = '1'";
Cursor cursor = managedQuery(ContactsContract.Contacts.CONTENT_URI,null, selection, null, null);
startManagingCursor(cursor);
String[] columns = new String[] {
ContactsContract.Contacts.DISPLAY_NAME
};
int[] to = new int[] { android.R.id.text1 };
SimpleCursorAdapter adapter = new SimpleCursorAdapter(this, android.R.layout.simple_list_item_multiple_choice, cursor, columns, to);
this.setListAdapter(adapter);
Button finishButton = (Button) this.findViewById(R.id.finishButton);
finishButton.setOnClickListener(new OnClickListener() {
public void onClick(View v) {
SimpleCursorAdapter adapter = (SimpleCursorAdapter) nominateContactsActivity.this.getListAdapter();
ListView lv = nominateContactsActivity.this.getListView();
SparseBooleanArray selectedItems = lv.getCheckedItemPositions();
Cursor contactsCursor = adapter.getCursor();
/*for (long id : lv.getCheckedItemIds()) {
String selection = ContactsContract.CommonDataKinds.Phone.CONTACT_ID + " = ?";
String[] args = new String[] { String.valueOf(contactId) };
Cursor cursor=managedQuery(ContactsContract.CommonDataKinds.Phone.CONTENT_URI, null, selection, args, null);
}*/
for (long id : lv.getCheckedItemIds()) {
long contactId = contactsCursor.getInt(contactsCursor.getColumnIndex(BaseColumns._ID));
String selection = ContactsContract.CommonDataKinds.Phone.CONTACT_ID + " = ?";
String[] args = new String[] { String.valueOf(contactId) };
Cursor cursor=managedQuery(ContactsContract.CommonDataKinds.Phone.CONTENT_URI, null, selection, args, null);
if (cursor.moveToFirst()) {
strName=cursor.getString(cursor.getColumnIndex(ContactsContract.CommonDataKinds.Phone.DISPLAY_NAME));
strTelNo = cursor.getString(cursor.getColumnIndex(ContactsContract.CommonDataKinds.Phone.NUMBER));
}
;}
try {
//Name not operationally useful - why bother storing it - keep this in case later implemented.
//contactsArray.add(new BasicNameValuePair ("name", strName));
contactsArray.add(new BasicNameValuePair("number", strTelNo));
} catch(Exception e){
e.printStackTrace();
}
try {
storeContacts();
} catch (ClientProtocolException e) {
// TODO Auto-generated catch block
e.printStackTrace();
} catch (IOException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
}
});
}
public void storeContacts() throws ClientProtocolException, IOException{
SharedPreferences userPrefs = this.getSharedPreferences("PREFS_NAME", 0);
Editor edit = userPrefs.edit();
//edit.remove("contactsData").commit();
String formattedString = contactsArray.toString()
.replace("number=", "") //remove number name
.replace(" ","") //remove spaces
.replace("[", "") //remove the right bracket
.replace("]", ""); //remove the left bracket
edit.putString("contactsData", formattedString);
edit.commit();
String name = userPrefs.getString("Name", null);
String test = userPrefs.getString("contactsData", null);
Log.d("", formattedString);
Log.d("test = ", test);
Intent myIntent = new Intent(nominateContactsActivity.this, rootMenuActivity.class);
startActivity(myIntent);
String textSMS = "You have been nominated as a contact by " + name +". Check out www.mywebsite.com for info";
String retrievedContacts = userPrefs.getString("contactsData", null);
String textPhoneNo;
textPhoneNo = retrievedContacts;
//textSMS = "My current location is: " + currentLocation;
String phoneNo = textPhoneNo;
try {
SmsManager smsManager = SmsManager.getDefault();
smsManager.sendTextMessage(phoneNo, null, textSMS, null, null);
Toast.makeText(getApplicationContext(), "SMS Sent!", Toast.LENGTH_LONG).show();
Intent myIntent1 = new Intent(nominateContactsActivity.this, rootMenuActivity.class);
startActivity(myIntent1);
}
catch (Exception e) {
Toast.makeText(getApplicationContext(),
"SMS failed, please try again later!",
Toast.LENGTH_LONG).show();
e.printStackTrace();
}
上述代码工作正常，除了返回错误的联系人。这是一个滚动问题，复选框的ID丢失了吗？请帮忙!!
谢谢

答案 0 :(得分：0)
onClick中，你有适配器。从中，您可以获得联系人的光标。
Cursor contactsCursor = adapter.getCursor();
contactsCursor.moveToPosition(selectedPosition);
long contactId = contactsCursor.get(contactsCursor.getColumnIndex(BaseColumn._ID));
从那里，您可以像这样搜索电话：
String selection = ContactsContract.CommonDataKinds.Phone.CONTACT_ID + " = ?";
String[] args = new String[] { String.valueOf(contactId) };
Cursor cursor=managedQuery(ContactsContract.CommonDataKinds.Phone.CONTENT_URI, null, selection, args, null);
if (cursor.moveToFirst()) {
// Get content here
}
从那里你可以按照你原来的方式使用获得的光标。
你可以简单地循环：
for (long contactId : lv.getCheckedItemIds()) {
String selection = ContactsContract.CommonDataKinds.Phone.CONTACT_ID + " = ?";
String[] args = new String[] { String.valueOf(contactId) };
Cursor cursor=managedQuery(ContactsContract.CommonDataKinds.Phone.CONTENT_URI, null, selection, args, null);
if (cursor.moveToFirst()) {
// Get content here
}
}
