  1. POSearch in a ListView doesn't work properly
    text
    copied!<p>I have a listView with about 30 items in it and have added a search function to it via an editText. When I type 'a' in the textfield everything that starts with an 'a' shows up on the list but when I type another letter the list disappears even tho the list contains an item with 'a' + the other letter i typed. </p> <p>Another thing that confuses me is that there is an item in the list called IWU Trading and thats the only item I can search for, means that if I type 'I' + 'W' the item shows up in the listView. But if I type 'a' + 'r' an item that is named 'art' dosent show up.</p> <p>My question(s). How can I do to make this search function work? Why does it act like it does?</p> <p>My XML</p> <pre><code> &lt;EditText android:id="@+id/searchEditText" android:layout_width="wrap_content" android:layout_height="wrap_content" android:layout_alignParentLeft="true" android:layout_below="@+id/selectCustomerTextView" android:layout_marginTop="20dp" android:hint="@string/typeToSearch" android:ems="10" android:imeOptions="actionDone" android:inputType="textNoSuggestions"/&gt; &lt;ListView android:id="@+id/list_view" android:layout_width="fill_parent" android:layout_height="wrap_content" android:layout_above="@+id/nextButton" android:layout_alignParentLeft="true" android:layout_below="@+id/searchEditText" android:choiceMode="singleChoice" android:dividerHeight="5dp" &gt; &lt;/ListView&gt; </code></pre> <p>My code:</p> <pre><code> private ArrayAdapter&lt;Customer&gt; _oldAdapter = null; public void onCreate(Bundle savedInstanceState) { super.onCreate( savedInstanceState ); setContentView(R.layout.activity_customer_pick); EditText searchText = (EditText) findViewById(R.id.searchEditText); ListView listView = (ListView) findViewById(R.id.list_view); listView.setClickable(true); searchText.addTextChangedListener(filterTextWatcher); _oldAdapter = _phoneDAL.BindValues(this); listView.setAdapter(_oldAdapter); listView.setOnItemClickListener(new OnItemClickListener() { public void onItemClick(AdapterView&lt;?&gt; arg0, View arg1, int arg2, long arg3) { String s = _oldAdapter.getItem(arg2).toString(); _listViewPostion = arg2; Toast.makeText(CustomerPick.this, "Du valde: " + s, arg2).show(); } }); } </code></pre> <p>The search method:</p> <pre><code>private TextWatcher filterTextWatcher = new TextWatcher() { public void afterTextChanged(Editable s) { } public void beforeTextChanged(CharSequence s, int start, int count, int after) { } public void onTextChanged(CharSequence s, int start, int before, int count) { ArrayAdapter&lt;Customer&gt; _adapter = new ArrayAdapter&lt;Customer&gt;(CustomerPick.this, android.R.layout.simple_list_item_single_choice, new ArrayList&lt;Customer&gt;()); ListView listView = (ListView) findViewById(R.id.list_view); int textLength = s.length(); if(textLength == 0){ listView.setAdapter(_oldAdapter); return; } for (int i = 0; i &lt; listView.getAdapter().getCount(); i++) { String word = _oldAdapter.getItem(i).getCustName().toLowerCase(); if (textLength &lt;= word.length()) { if(s.toString().equalsIgnoreCase(word.substring(0, textLength))) { _adapter.add(_oldAdapter.getItem(i)); } } } listView.setAdapter(_adapter); } }; </code></pre> <p>}</p> <p>My CustomerClass (private ArrayAdapter _oldAdapter = null;)</p> <pre><code>public class Customer { private final int _custNumber; private final String _custName; public Customer(int custNumber, String custName){ _custNumber = custNumber; _custName = custName; } public int getCustNumber() { return _custNumber; } public String getCustName() { return _custName; } @Override public String toString(){ return _custName; } </code></pre> <p>}</p>
