public void onCommitCompletion (CompletionInfo completion)

Parameters

completion	The auto complete text the user has selected.

public void onFilterComplete (int count)

Added in API level 1

Notifies the end of a filtering operation.

Parameters

count	the number of values computed by the filter

public boolean onKeyDown (int keyCode, KeyEvent event)

Added in API level 1

Default implementation of KeyEvent.Callback.onKeyDown(): perform press of the view when KEYCODE_DPAD_CENTER or KEYCODE_ENTER is released, if the view is enabled and clickable.

Key presses in software keyboards will generally NOT trigger this listener, although some may elect to do so in some situations. Do not rely on this to catch software key presses.

Parameters

keyCode	A key code that represents the button pressed, from `KeyEvent`.
event	The KeyEvent object that defines the button action.

Returns

If you handled the event, return true. If you want to allow the event to be handled by the next receiver, return false.

public boolean onKeyPreIme (int keyCode, KeyEvent event)

Added in API level 3

Handle a key event before it is processed by any input method associated with the view hierarchy. This can be used to intercept key events in special situations before the IME consumes them; a typical example would be handling the BACK key to update the application's UI instead of allowing the IME to see it and close itself.

Parameters

keyCode	The value in event.getKeyCode().
event	Description of the key event.

Returns

If you handled the event, return true. If you want to allow the event to be handled by the next receiver, return false.

public boolean onKeyUp (int keyCode, KeyEvent event)

Added in API level 1

Default implementation of KeyEvent.Callback.onKeyUp(): perform clicking of the view when KEYCODE_DPAD_CENTER or KEYCODE_ENTER is released.

Key presses in software keyboards will generally NOT trigger this listener, although some may elect to do so in some situations. Do not rely on this to catch software key presses.

Parameters

keyCode	A key code that represents the button pressed, from `KeyEvent`.
event	The KeyEvent object that defines the button action.

Returns

If you handled the event, return true. If you want to allow the event to be handled by the next receiver, return false.

public void onWindowFocusChanged (boolean hasWindowFocus)

Added in API level 1

Called when the window containing this view gains or loses focus. Note that this is separate from view focus: to receive key events, both your view and its window must have focus. If a window is displayed on top of yours that takes input focus, then your own window will lose focus but the view focus will remain unchanged.

Parameters

hasWindowFocus	True if the window containing this view now has focus, false otherwise.

public void performCompletion ()

Added in API level 1

Performs the text completion by converting the selected item from the drop down list into a string, replacing the text box's content with this string and finally dismissing the drop down menu.

public void performValidation ()

Added in API level 1

If a validator was set on this view and the current string is not valid, ask the validator to fix it.

public void setAdapter (T adapter)

Added in API level 1

Changes the list of data used for auto completion. The provided list must be a filterable list adapter.

The caller is still responsible for managing any resources used by the adapter. Notably, when the AutoCompleteTextView is closed or released, the adapter is not notified. A common case is the use of CursorAdapter, which contains a Cursor that must be closed. This can be done automatically (see startManagingCursor()), or by manually closing the cursor when the AutoCompleteTextView is dismissed.

Parameters

adapter	the adapter holding the auto completion data

public void setCompletionHint (CharSequence hint)

Added in API level 1

Sets the optional hint text that is displayed at the bottom of the the matching list. This can be used as a cue to the user on how to best use the list, or to provide extra information.

Added in API level 1

Displays the drop down on screen.

Protected Methods

protected CharSequence convertSelectionToString (Object selectedItem)

Added in API level 1

Converts the selected item from the drop down list into a sequence of character that can be used in the edit box.

Parameters

selectedItem	the item selected by the user for completion

Returns

a sequence of characters representing the selected suggestion

protected Filter getFilter ()

Added in API level 1

Returns the Filter obtained from getFilter(), or null if setAdapter(T) was not called with a Filterable.

protected void onAttachedToWindow ()

Added in API level 1

This is called when the view is attached to a window. At this point it has a Surface and will start drawing. Note that this function is guaranteed to be called before onDraw(android.graphics.Canvas), however it may be called any time before the first onDraw -- including before or after onMeasure(int, int).

protected void onDetachedFromWindow ()

Added in API level 1

This is called when the view is detached from a window. At this point it no longer has a surface for drawing.

protected void onDisplayHint (int hint)

Added in API level 8

Gives this view a hint about whether is displayed or not. For instance, when a View moves out of the screen, it might receives a display hint indicating the view is not displayed. Applications should not rely on this hint as there is no guarantee that they will receive one.

Parameters

hint	A hint about whether or not this view is displayed: `VISIBLE` or `INVISIBLE`.

protected void onFocusChanged (boolean focused, int direction, Rect previouslyFocusedRect)

Added in API level 1

Called by the view system when the focus state of this view changes. When the focus change event is caused by directional navigation, direction and previouslyFocusedRect provide insight into where the focus is coming from. When overriding, be sure to call up through to the super class so that the standard focus handling will occur.

Parameters

focused	True if the View has focus; false otherwise.
direction	The direction focus has moved when requestFocus() is called to give this view focus. Values are `FOCUS_UP`, `FOCUS_DOWN`, `FOCUS_LEFT`, `FOCUS_RIGHT`, `FOCUS_FORWARD`, or `FOCUS_BACKWARD`. It may not always apply, in which case use the default.
previouslyFocusedRect	The rectangle, in this view's coordinate system, of the previously focused view. If applicable, this will be passed in as finer grained information about where the focus is coming from (in addition to direction). Will be `null` otherwise.

protected void performFiltering (CharSequence text, int keyCode)

Added in API level 1

Starts filtering the content of the drop down list. The filtering pattern is the content of the edit box. Subclasses should override this method to filter with a different pattern, for instance a substring of text.

Parameters

text	the filtering pattern
keyCode	the last character inserted in the edit box; beware that this will be null when text is being added through a soft input method.

protected void replaceText (CharSequence text)

Added in API level 1

Performs the text completion by replacing the current text by the selected item. Subclasses should override this method to avoid replacing the whole content of the edit box.

Parameters

text	the selected suggestion in the drop down list

protected boolean setFrame (int l, int t, int r, int b)

Added in API level 1

Assign a size and position to this view. This is called from layout.

Parameters

l	Left position, relative to parent
t	Top position, relative to parent
r	Right position, relative to parent
b	Bottom position, relative to parent

Returns

true if the new size and position are different than the previous ones

使用方法如下：

public class CountriesActivity extends Activity {
protected void onCreate(Bundle icicle) {
super.onCreate(icicle);
setContentView(R.layout.countries);

ArrayAdapter<String> adapter = new ArrayAdapter<String>(this,
android.R.layout.simple_dropdown_item_1line, COUNTRIES);
AutoCompleteTextView textView = (AutoCompleteTextView)
findViewById(R.id.countries_list);
textView.setAdapter(adapter);
}

private static final String[] COUNTRIES = new String[] {
"Belgium", "France", "Italy", "Germany", "Spain"
};
}

在AutoCompleteTextview的使用中关键是Adapter的构建和应用
