はArrayList
問題なく入力されているように見えますが、どのアプローチを使用しても、アダプターにデータを入力させることができないようです。ArrayList
に、またに追加してみましたArrayAdapter
。いずれにせよ、私はそのAutoCompleteTextView
レベルで、またはArrayAdapter
それ自体で応答を得ることができません(そしてもちろん、それAutoCompleteTextView
は何もしていません)。誰かが何が悪いのかわかりますか?
public class MainActivity extends Activity implements TextWatcher {
// private AutoCompleteView autoComplete;
public String TAG = new String("MAINACTIVITY");
public ArrayAdapter<String> autoCompleteAdapter;
public AutoCompleteTextView autoComplete;
public InputStream inputStream;
public List<String> data;
/** Called when the activity is first created. */
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
data = new ArrayList<String>();
autoCompleteAdapter = new ArrayAdapter<String>(this,android.R.layout.simple_dropdown_item_1line, data);
autoCompleteAdapter.setNotifyOnChange(true);
autoComplete = (AutoCompleteTextView) findViewById(R.id.acsayt);
autoComplete.setHint(R.string.search_hint);
autoComplete.setThreshold(2);
autoComplete.addTextChangedListener(this);
autoComplete.setAdapter(autoCompleteAdapter);
}
// uphold TextWatcher interface methods
public void afterTextChanged(Editable s) {
}
public void beforeTextChanged(CharSequence s, int start, int count, int after) {
}
public void onTextChanged(CharSequence s, int start, int before, int count) {
Log.d(TAG, "I detected a text change " + s.toString());
data.clear();
queryWebService();
}
private void queryWebService() {
new Thread(new Runnable() {
public void run() {
Log.d(TAG, "spawned thread");
// Code in here to set up http connection, query webservice ...
// parse the JSON response & add items to adapter
try {
JSONArray jArray = new JSONArray(resultString);
int length = jArray.length();
int countedValues, capturedValues;
Log.d(TAG, "response had " + length + " items");
int i = 0;
while (i < length) {
JSONObject internalObject = jArray.getJSONObject(i);
String vehicleName = internalObject.getString("name").toString();
Log.d(TAG, "vehicle name is " + vehicleName);
try {
data.add(vehicleName);
autoCompleteAdapter.add(vehicleName); // not working
} catch (Exception e) {
e.printStackTrace();
}
countedValues = data.size(); // correctly reports 20 values
capturedValues = autoCompleteAdapter.getCount(); // is zero
Log.d(TAG, "array list holds " + countedValues + " values");
Log.d(TAG, "array adapter holds " + capturedValues + " values");
i++;
}
} catch (Exception e) {
Log.d(TAG, "JSON manipulation err: " + e.toString());
}
}
}).start();
}
}
LogCatは、data.size()からの期待値数を示しますが、autoCompleteAdapter.getCount()からはゼロを示します。
