如何从AutoCompleteTextView选择项创建Toast？

Question

我是一个新手android学习者.我正在尝试创建吐司,当用户选择AutoCompleteTextView中的项目时.我正在读取strings.xml中的值,这是正常工作,但我很困惑我如何(甚至处理程序)我需要创建吐司.下面是我的代码1- activity.xml

<AutoCompleteTextView android:id="@+id/myautocomplete"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:layout_marginTop="110dp"
/>

strings.xml
<string-array name="termsarray">
<item>emulator</item>
<item>ant</item>
<item>string.xml</item>
    <item>activity</item>
    <item>workspace</item>
    <item>adt</item>
    <item>manifest.xml</item>
    <item>package</item>
    <item>layout</item>
    <item>toast</item>
    <item>adb</item>
</string-array> 
//activity.java
public class TermActivity extends Activity {

 String[] categories;

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    categories=getResources().getStringArray(R.array.termsarray);
    setContentView(R.layout.activity_term);

    ArrayAdapter<String> adapter = new ArrayAdapter<String>(
            this,
            android.R.layout.simple_dropdown_item_1line, categories);
    AutoCompleteTextView textView = 
            (AutoCompleteTextView) findViewById(R.id.myautocomplete);
    textView.setThreshold(3);
    textView.setAdapter(adapter); 

}

处理听众.试试这个:

textView.setOnItemClickListener(new AdapterView.OnItemClickListener() {
      @Override
      public void onItemClick(AdapterView<?> parent, View view, int position, long id) {
              Toast.makeText(context, "Position clicked: " + position, Toast.LENGTH_SHORT).show();
      }
});
