它一直崩溃。我认为这与意图有关。请帮忙。
package com.SMARTlab.twitterapp;

import android.widget.Button;

public class TwitterApp extends Activity {

@Override

super.onCreate(savedInstanceState);
setContentView(R.layout.main);
Button search = (Button)findViewById(R.id.search_button);

}
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

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。

这是AndroidManifest.xml的内容。

最佳答案
确保在您的AndroidManifest中将Twitter注册为活动。
关于java - 编译但崩溃的android应用。与 Intent 有关吗？救命，我们在Stack Overflow上找到一个类似的问题：https://stackoverflow.com/questions/6310138/
