    <p>My main activity code:</p> <pre><code>// here you put all your data. String[] dataArray = { "Amit sharma Kumar", "Hisham Kumar Munner", "Vineet John Chaturvedi", "Lucky Kumar Verma" }; ArrayList&lt;String&gt; alAutoCompleteList; AutoCompleteTextView acTV; ArrayAdapter&lt;String&gt; adapter1; @Override public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.activity_main); // etAuto = (EditText) findViewById(R.id.etAuto); acTV = (AutoCompleteTextView) findViewById(R.id.acTV); // Arraylist alAutoCompleteList = new ArrayList&lt;String&gt;(); adapter1 = new ArrayAdapter&lt;String&gt;(MainActivity.this, android.R.layout.simple_dropdown_item_1line, alAutoCompleteList); acTV.addTextChangedListener(new TextWatcher() { @Override public void onTextChanged(CharSequence s, int start, int before, int count) { // TODO Auto-generated method stub if (acTV.enoughToFilter()) { acTV.showDropDown(); acTV.bringToFront(); } } @Override public void beforeTextChanged(CharSequence s, int start, int count, int after) { // TODO Auto-generated method stub alAutoCompleteList.clear(); } @Override public void afterTextChanged(Editable s) { // TODO Auto-generated method stub String acText = acTV.getText().toString().trim(); for (String item : dataArray) { if (item.toLowerCase().contains(acText.toLowerCase())) { alAutoCompleteList.add(item); } } acTV.setThreshold(4); acTV.setAdapter(adapter1); acTV.showDropDown(); } }); </code></pre> <hr> <p>When I search for "sharma" and press a space after that the suggestions go off. I want those suggestions to stay there. I have tried to do everything but didn't got any success. Can someone please help?</p> <p>Edit: Can someone please try this code on their emulators? Just add a <code>AutoCompleteTextView</code> in xml and run it.</p>

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.
