您好朋友，



我正在构建一个Android应用程序，其中我的目标是向用户提供我的应用程序的建议

<每当他使用editText在任何应用程序中输入内容时，都会发出
文本。



这可能吗？如果我的应用程序作为服务运行，或者还有其他方式。

确定。你需要什么称为自动完成文本。这是基于输入的前几个字母向用户建议的文本，其中考虑了您包含的可能建议或先前输入的文本。

  public   class  CountriesActivity  extends 活动{
  protected   void  onCreate（Bundle icicle）{
 超 .onCreate（冰柱）; 
 setContentView（R.layout.countries）; 
 
 ArrayAdapter< string> adapter =  new  ArrayAdapter< string>（ this ，

 findViewById（R.id.countries_list）;

Hello freinds,

I am building an android app, in which i am aiming to give user suggestions of my application

text whenever he uses editText to enter something in any application.

Is this possible? If my app runs as a service, or is there some other way.

Thanks for your help in advance!!

解决方案

Sure. What you need is called AutoComplete text. This is text suggested to the user based on the first few letters typed, which takes into consideration possible suggestions you include, or previous text typed.

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[] {
         "option1", "option2", "bla bla bla", "etc.", "chose me"
     };
 }</string></string>
