本文介绍了安卓：不显示列表自动提示时，选择的项目的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！
问题描述
我在做自动完成使用TextView的在我的应用程序的一些东西。我得到的建议当用户键入任何东西。但是，我有一个查询，当用户类型和水龙头上自动完成TextView的建议列表中，则更多的建议上来。我想，当用户点击该名单上，并不想显示更多选项有限制搜索结果。我怎样才能克服这种情况。
这是我的全类，我的工作：
公共类WikiSuggestActivity延伸活动{
公共字符串的数据;
公开名单＆LT;串GT;建议;
公共AutoCompleteTextView自动完成;
公共ArrayAdapter＆LT;串GT; aAdapter;/ **当第一次创建活动调用。 * /

I was doing some stuff using autocomplete textview in my application. I'm getting suggestion when user types anything. But, I have one query, when user types and taps on the suggested list on the autocomplete textview, then more suggestions comes up. I want to limit the search results when user taps on the list and don't want to show more options there. How can I overcome this situation.
This is my full class, which I'm working on:
public class WikiSuggestActivity extends Activity {
public String data;
public List<String> suggest;
public AutoCompleteTextView autoComplete;
public ArrayAdapter<String> aAdapter;
/** Called when the activity is first created. */
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
suggest = new ArrayList<String>();
autoComplete = (AutoCompleteTextView) findViewById(R.id.autoCompleteTextView1);
autoComplete.addTextChangedListener(new TextWatcher() {
public void afterTextChanged(Editable editable) {
// TODO Auto-generated method stub
}
public void beforeTextChanged(CharSequence s, int start, int count,
int after) {
// TODO Auto-generated method stub
}
public void onTextChanged(CharSequence s, int start, int before,
int count) {
String newText = s.toString();
new getJson().execute(newText);
}
});
}
class getJson extends AsyncTask<String, String, String> {
@Override
protected String doInBackground(String... key) {
String newText = key[0];
newText = newText.trim();
newText = newText.replace(" ", "+");
try {
HttpClient hClient = new DefaultHttpClient();
HttpGet hGet = new HttpGet(
"http://en.wikipedia.org/w/api.php?action=opensearch&search="
+ newText + "&limit=8&namespace=0&format=json");
ResponseHandler<String> rHandler = new BasicResponseHandler();
data = hClient.execute(hGet, rHandler);
suggest = new ArrayList<String>();
JSONArray jArray = new JSONArray(data);
for (int i = 0; i < jArray.getJSONArray(1).length(); i++) {
String SuggestKey = jArray.getJSONArray(1).getString(i);
suggest.add(SuggestKey);
}
} catch (Exception e) {
Log.w("Error", e.getMessage());
}
runOnUiThread(new Runnable() {
public void run() {
aAdapter = new ArrayAdapter<String>(
getApplicationContext(), R.layout.item, suggest);
autoComplete.setAdapter(aAdapter);
aAdapter.notifyDataSetChanged();
}
});
return null;
}
}
}
Any guidance will be appreciated.
