问题描述
我设计的应用程序中，我想允许用户选择将消息发送给多个联系人。使用下面的code我已经成功地获取了用户的列表中，列表视图用复选框。现在我想，当用户点击完成按钮，在电话号码的所有选定的联系人应检索EDITTEXT 格式例如约翰1 + 919898xxxxxx>，里克＆LT + 919988xxxxxx> ，并包含所有电话号码的只是10位数字，即9898xxxxxx应存放在用逗号（9898xxxxxx，9988xxxxxx）分隔字符串自动。我如何能做到的要求。

i am designing application in which i want to allow user to select multiple contact to send messages to. I have successfully retrieved the list of user in the listview with checkbox using the following code. now i want that when the user clicks on the "DONE" button, the PHONE NUMBER of the all selected contact should be retrieved in EDITTEXT in format like John <+919898xxxxxx>, Rick <+919988xxxxxx> and also that all the phone numbers containing just 10 digits i.e "9898xxxxxx" should be stored in a string seperated by comma (9898xxxxxx, 9988xxxxxx) automatically. how can i accomplish the requirement.
public class ContactsActivity extends ListActivity {
protected static final String TAG = null;
public String[] Contacts = {};
public int[] to = {};
public ListView myListView;
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_contacts);
final Button done_Button = (Button) findViewById(R.id.done_Button);
final Button clear_Button =(Button) findViewById(R.id.clear_Button);
Cursor mCursor = getContacts();
startManagingCursor(mCursor);
ListAdapter adapter = new SimpleCursorAdapter(this, android.R.layout.simple_list_item_multiple_choice, mCursor,
Contacts = new String[] {ContactsContract.Contacts.DISPLAY_NAME },
to = new int[] { android.R.id.text1 });
setListAdapter(adapter);
myListView = getListView();
myListView.setItemsCanFocus(false);
myListView.setChoiceMode(ListView.CHOICE_MODE_MULTIPLE);
clear_Button.setOnClickListener(new View.OnClickListener() {
public void onClick(View v) {
Toast.makeText(getApplicationContext(),"Selections Cleared", Toast.LENGTH_SHORT).show();
ClearSelections();
}
});
/** When 'Done' Button Pushed: **/
done_Button.setOnClickListener(new View.OnClickListener() {
public void onClick (View v){
Log.i(TAG,":Done Button Selected:");
SparseBooleanArray selectedPositions = myListView.getCheckedItemPositions();
Log.i(TAG,"Number of Checked Positions: " + selectedPositions.size());
for (int i=0; i<selectedPositions.size(); i++) {
if (selectedPositions.get(selectedPositions.keyAt(i)) == true) {
//do stuff
}
}
}
});
}
private void ClearSelections() {
int count = this.myListView.getAdapter().getCount();
for (int i = 0; i < count; i++) {
this.myListView.setItemChecked(i, false);
}
}
private Cursor getContacts() {
// Run query
Uri uri = ContactsContract.Contacts.CONTENT_URI;
String[] projection = new String[] { ContactsContract.Contacts._ID,
ContactsContract.Contacts.DISPLAY_NAME};
String selection = ContactsContract.Contacts.HAS_PHONE_NUMBER + " = '"
+ ("1") + "'";
String[] selectionArgs = null;
String sortOrder = ContactsContract.Contacts.DISPLAY_NAME
+ " COLLATE LOCALIZED ASC";
return managedQuery(uri, projection, selection, selectionArgs,
sortOrder);
}
@Override
public boolean onCreateOptionsMenu(Menu menu) {
getMenuInflater().inflate(R.menu.activity_contacts, menu);
return true;
}
}
解决方案
configured it finally
done_Button.setOnClickListener(new View.OnClickListener() {
public void onClick (View v){
String name = null;
String number = null;
long [] ids = myListView.getCheckedItemIds();
for(long id : ids) {
Cursor contact = getContentResolver().query(ContactsContract.CommonDataKinds.Phone.CONTENT_URI, null,
ContactsContract.CommonDataKinds.Phone.CONTACT_ID + " = ?", new String[] { id + "" }, null);
while(contact.moveToNext()){
name = contact.getString(contact.getColumnIndex(ContactsContract.Contacts.DISPLAY_NAME));
//name+=name;
number = contact.getString(contact.getColumnIndex(ContactsContract.CommonDataKinds.Phone.NUMBER));
//number+=number;
}
Toast.makeText(getApplicationContext(), "Name: " +name + "\n" + "Number: " + number , Toast.LENGTH_LONG).show();
}
}
});
