[编辑] 我正在尝试使用twitter4j版本4.0.4作为库从Twitter搜索一些推文。这是我的方法
public void processAll(View view){
Log.d("click","OKE");
ConfigurationBuilder cb = new ConfigurationBuilder();
cb.setDebugEnabled(true)
.setOAuthConsumerKey("xxxxx")
.setOAuthConsumerSecret("xxxx")
.setOAuthAccessToken("7xxxxL")
.setOAuthAccessTokenSecret("xxxxx");
TwitterFactory tf = new TwitterFactory(cb.build());
Twitter twitter = tf.getInstance();
Log.d("connected","OKE");
try {
Query query = new Query("handsome");
Log.d("TEST","OKE");
QueryResult result = twitter.search(query);
List<Status> tweets = result.getTweets();
for (Status tweet : tweets) {
Log.d("RESULT","@" + tweet.getUser().getScreenName() + " - " + tweet.getText());
}
}
catch (TwitterException te) {
te.printStackTrace();
Log.d("RESULT","Failed to search tweets: " + te.getMessage());
return;
}
}
但是在调用此方法时我的应用程序停止了。

对
的引用 QueryResult result = twitter.search(query);
这里是我的完整logcat

提前致谢！
答案 0 :(得分：2)
你正在抛出一个NetworkOnMainThreadException，这意味着你试图在应用程序主线程上运行网络代码（即通过twitter API运行搜索）。
您需要使用AsyncTask之类的内容（请参阅docs）将此代码移动到后台线程中。
我建议阅读文档以及对上一个问题的回答：How to fix android.os.NetworkOnMainThreadException?
