    <p>I am using a TextWatcher to listen to key inputs. When user types '@', I open up a listactivity and user has to choose from the list. Once choosen, I place the selected item's text(including the initial @) to the edittext and normal editing goes on. </p> <p>The issue is that when I press backspace, the string I get in aftertextchanged event is wrong, and the listactivity again pops up.</p> <pre><code>editText.addTextChangedListener(new TextWatcher() { @Override public void onTextChanged(CharSequence s, int start, int before, int count) { } @Override public void beforeTextChanged(CharSequence s, int start, int count, int after) { } @Override public void afterTextChanged(Editable s) { String str = s.toString(); if (str.length() &gt; 0) { if (str.substring(str.length() - 1).equals("@")) { Intent i = new Intent(MessageComposeActivity.this, MembersListActivity.class); startActivityForResult(i, Util.MEMBERS_LIST); } } } }); </code></pre> <p>And in onActivityResult:</p> <pre><code>@Override protected void onActivityResult(int requestCode, int resultCode, Intent data) { super.onActivityResult(requestCode, resultCode, data); if (requestCode == Util.MEMBERS_LIST) if (resultCode == RESULT_OK) { editText.setText(editText.getText().toString() + data.getExtras().get("screenname") + " "); editText.setSelection(editText.getText().length()); } } </code></pre> <p><strong>For example:</strong></p> <p>In EditText I type '@', and the activity pops up and I choose 'James'. The EditText now shows @James. If I press backspace once or twice, the listactivity again pops up while the EditText shows @Jam.</p> <p>PS: The afterTextChanged() is called twice sometimes for a backspace (or any key), on 2nd execution of afterTextChanged() I get wrong input string. On first execution of afterTextChanged() I get @Jam, and on 2nd execution I get '@' hence listactivity pops up.</p> <p><strong>Question:</strong> Why afterTextChanged() is called twice, AND why on 2nd execution I get wrong text?</p> <p>Thanks a lot.</p>

    1. COPlease don't "beg the bug". Chances are it isn't a bug in the library .. clearly state the problem/question and see what comes of it.

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.
