 AutoCompleteTextView ：是一个输入框，只不过多了一个自动填充功能

 1 自动填充控件

		  <AutoCompleteTextView android:id="@+id/autoComplete"   
		                        android:layout_width="fill_parent"   
		                        android:layout_height="wrap_content"/> 

 2 初始化自动填充的控件

  

		//自动填充
    private static final String[] COUNTRIES = {"China","Russia","Germany",  
        "Ukraine","Belarus","USA","China1","China2","USA1"}; 


     //初始化创建 自动补充的 文本框 
	private void initAutoComplete(){
		  //创建一个ArrayAdapter  
        ArrayAdapter<String> adapter = new ArrayAdapter<String>(this,  
                android.R.layout.simple_dropdown_item_1line,COUNTRIES);  
		 AutoCompleteTextView autoComplete = (AutoCompleteTextView) findViewById( R.id.autoComplete);
		//将AutoCompleteTextView与ArrayAdapter进行绑定  
	    autoComplete.setAdapter(adapter);  
	    //设置AutoCompleteTextView输入1个字符就进行提示  
        autoComplete.setThreshold(1);
	}
