Twitter REST API v1不再激活。我需要做什么修改才能在API v1.1中运行此代码。这是我的代码从twitter从特定的uri这是用于API v1 -
public class TwitterFeedActivity extends ListActivity {
private ArrayList<Tweet> tweets = new ArrayList<Tweet>();
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
new MyTask().execute();
}
private class MyTask extends AsyncTask<Void, Void, Void> {
private ProgressDialog progressDialog;
protected void onPreExecute() {
progressDialog = ProgressDialog.show(TwitterFeedActivity.this,
"", "Loading. Please wait...", true);
}
@Override
protected Void doInBackground(Void... arg0) {
try {
HttpClient hc = new DefaultHttpClient();
HttpGet get = new
HttpGet("http://search.twitter.com/search.json?q=android");
HttpResponse rp = hc.execute(get);
if(rp.getStatusLine().getStatusCode() == HttpStatus.SC_OK)
{
String result = EntityUtils.toString(rp.getEntity());
JSONObject root = new JSONObject(result);
JSONArray sessions = root.getJSONArray("results");
for (int i = 0; i < sessions.length(); i++) {
JSONObject session = sessions.getJSONObject(i);
Tweet tweet = new Tweet();
tweet.content = session.getString("text");
tweet.author = session.getString("from_user");
tweets.add(tweet);
}
}
} catch (Exception e) {
Log.e("TwitterFeedActivity", "Error loading JSON", e);
}
return null;
}
@Override
protected void onPostExecute(Void result) {
progressDialog.dismiss();
setListAdapter(new TweetListAdaptor(
TwitterFeedActivity.this, R.layout.list_item, tweets));
}
}
private class TweetListAdaptor extends ArrayAdapter<Tweet> {
private ArrayList<Tweet> tweets;
public TweetListAdaptor(Context context,
int textViewResourceId,
ArrayList<Tweet> items) {
super(context, textViewResourceId, items);
this.tweets = items;
}
@Override
public View getView(int position, View convertView, ViewGroup parent) {
View v = convertView;
if (v == null) {
LayoutInflater vi = (LayoutInflater)
getSystemService(Context.LAYOUT_INFLATER_SERVICE);
v = vi.inflate(R.layout.list_item, null);
}
Tweet o = tweets.get(position);
TextView tt = (TextView) v.findViewById(R.id.toptext);
TextView bt = (TextView) v.findViewById(R.id.bottomtext);
tt.setText(o.content);
bt.setText(o.author);
return v;
}
}
}
Tweet.java
public class Tweet {
String author;
String content;
}
问题可能在此代码
HttpGet("http://search.twitter.com/search.json?q=android");
您使用了错误的URL.....
"The Twitter REST API v1 is no longer active..."
必须使用REST API v1.1。用于获取twitter数据…
你必须遵循下面的URL…
"https://api.twitter.com/1.1/search/tweets.json?q=android"
注意:必须通过CONSUMER_KEY &CONSUMER_SECRET获取数据到URL…
关注这个"TWITTER控制台"..它将帮助你给你想要的输出与它的控制台…如果成功，那么在你的程序中实现它。
我已经获取了twitter TWEETS…这段代码可能对您有用..........
