所以我从一个线程中动态地构建我的列表视图，因此它可以异步工作。我刚刚实现了谷歌的 SwipeRefreshLayout。所以在 onRefresh 调用中我想重建列表。然而，我尝试的一切要么什么都不做，要么告诉我。
“只有创建视图层次结构的原始线程才能触及它的视图。”
列表是如何构建的
public void updateQueue(final ListView lstvw, Context ctx, final Boolean refresh) {
final String [] stringArray = stringArrayList.toArray(new String[stringArrayList.size()]);
adapter = new ArrayAdapter(ctx,android.R.layout.simple_list_item_1, stringArrayList);
new Thread(new Runnable() {
public void run() {
try {
try {
HttpClient httpclient = new DefaultHttpClient(); // Create HTTP Client
HttpGet httpget = new HttpGet("http://test.net/test.php"); // Set the action you want to do
HttpResponse response = httpclient.execute(httpget); // Executeit
HttpEntity entity = response.getEntity();
InputStream is = entity.getContent(); // Create an InputStream with the response
BufferedReader reader = new BufferedReader(new InputStreamReader(is, "iso-8859-1"), 8);
StringBuilder sb = new StringBuilder();
String line = null;
while ((line = reader.readLine()) != null) // Read line by line
sb.append(line + "\n");
String resString = sb.toString(); // Result is here
JSONArray json = new JSONArray(resString);
for(int i=0;i<json.length();i++){
JSONObject json_data = json.getJSONObject(i);
String jsonvalues = json_data.getString("title");
if (!jsonvalues.equals("")) {
stringArrayList.add(json_data.getString("artist") + " - " + json_data.getString("title"));
// .. get all value here
}
Log.e("TEST", "TEST RES E " + jsonvalues);
}
if (stringArrayList.isEmpty()) {
stringArrayList.add("No items currently in queue");
}
is.close(); // Close the stream
if (refresh) {
getActivity().runOnUiThread(new Runnable() {
public void run() {
lstvw.setVisibility(View.VISIBLE);
adapter.notifyDataSetChanged();
spinner.setVisibility(View.GONE);
}
});
}
//adapter.notifyDataSetChanged();
Log.e("TEST", "TEST RES Ended ");
}
catch (Exception e) {
Log.e("TESTAPP", "SOME Catch Error E " + e.toString());
}
}
catch (Exception e){
Log.e("TESTAPP", "SOME Error" + e.getMessage());
}
}
}).start();
}
}
onRefresh
swipeLayout = (SwipeRefreshLayout) rootView.findViewById(R.id.swipe_container);
swipeLayout.setColorScheme(android.R.color.holo_blue_bright,
android.R.color.holo_green_light,
android.R.color.holo_orange_light,
android.R.color.holo_red_light);
swipeLayout.setOnRefreshListener( new SwipeRefreshLayout.OnRefreshListener() {
@Override public void onRefresh() {
updateQueue(lstvw,ctx,true);
swipeLayout.setRefreshing(false);
}});
