最近在学习安卓开发，发现安卓中，很多控件都按照具体的功能来独立出来了，比如这个自动补全的控件。

废话不多说，先看下效果：

当我打aa的时候，就会提示出来。下面直接上代码核心部分

xml部分：

    <AutoCompleteTextView        android:layout_width="wrap_content"        android:layout_height="wrap_content"        android:hint="@string/app_name"        android:id="@+id/autoCompleteTextView"        android:layout_below="@+id/textView4"        android:layout_alignParentLeft="true"        android:layout_alignParentStart="true"        android:dropDownWidth="match_parent"/>

Activity部分：

 AutoCompleteTextView t;    ArrayAdapter adapter;    String[] array = {"aa", "vv", "bb", "ccadasfds", "dd123", "aa"};    /**     * ATTENTION: This was auto-generated to implement the App Indexing API.     * See https://g.co/AppIndexing/AndroidStudio for more information.     */    private GoogleApiClient client;    @Override    protected void onCreate(Bundle savedInstanceState) {        super.onCreate(savedInstanceState);        setContentView(R.layout.activity_main);        t = (AutoCompleteTextView) findViewById(R.id.autoCompleteTextView);        adapter = new ArrayAdapter<String>(this, android.R.layout.simple_list_item_1, array);        t.setAdapter(adapter);        // ATTENTION: This was auto-generated to implement the App Indexing API.        // See https://g.co/AppIndexing/AndroidStudio for more information.        client = new GoogleApiClient.Builder(this).addApi(AppIndex.API).build();<span style="white-space:pre"></span><span style="white-space:pre"></span>

<span style="white-space:pre"></span>//下面这部分，是点击空白处让键盘消失。        RelativeLayout mylayout = (RelativeLayout)findViewById(R.id.myLayout);        mylayout.setOnTouchListener(new View.OnTouchListener() {            @Override            public boolean onTouch(View v, MotionEvent event) {                InputMethodManager manager = (InputMethodManager)getSystemService(INPUT_METHOD_SERVICE);                return manager.hideSoftInputFromWindow(getCurrentFocus().getWindowToken(),0);            }        });    }
