java - 编译但崩溃的 Android 应用程序。与 Intent 有关吗？帮助

Question

它总是崩溃。我认为这与 Intent 有关。请帮忙。

    package com.SMARTlab.twitterapp;
    import android.app.Activity;
    import android.content.Intent;
    import android.os.Bundle;
    import android.view.View;
    import android.widget.Button;
    import android.widget.EditText;
    import android.widget.TextView;
    import twitter4j.*;

    public class TwitterApp extends Activity {
        /** Called when the activity is first created. */
        @Override
        public void onCreate(Bundle savedInstanceState) {
            super.onCreate(savedInstanceState);
            setContentView(R.layout.main);
            Button search = (Button)findViewById(R.id.search_button);
            search.setOnClickListener(search_OnClickListener);
        }
        public void onClick(View v)
        {
            switch (v.getId())
            {
            case R.id.search_button:
                Intent i = new Intent(this, com.SMARTlab.twitterapp.TwitterApp.class);
                startActivity(i);
                break;

            }
        }

        @SuppressWarnings("deprecation")
        private Button.OnClickListener search_OnClickListener = new Button.OnClickListener()
        {
            int queryRank = 0;
            private boolean evaluateRank(int rank)
            {
                if (rank > 10)
                return true;
                return false;
            }
            @Override 
            public void onClick(View v)
            {

                Twitter t = new TwitterFactory().getInstance();
                EditText ed = (EditText)findViewById(R.id.search_box);
                TextView txt = (TextView)findViewById(R.id.text_box);
                Query q = new Query(ed.getText().toString());
                QueryResult res = null;
                try
                {
                    res = t.search(q);
                    txt.setText("");

                }
                catch(TwitterException ex) {System.out.println(ex.toString());}
                for (Tweet tw : res.getTweets())
                {
                    try
                    {
                        long[] id = t.getRetweetedByIDs(tw.getId()).getIDs();
                        for (int x = 0; x < id.length; x++)
                            queryRank += 1;
                    } catch(TwitterException te) {}
                    if (evaluateRank(queryRank))
                    {
                        txt.append((String)"[" + tw.getFromUser() + "] " + tw.getText() + "\n");
                    }
                }
            }
        };
    }

这是 LogCat。

确保 Twitter 已在您的 AndroidManifest 中注册。作为一项 Activity 。
