Android的意图不工作

Question

所以我有这些代码

main.java

definisi.java

     ActionBar actionBar = getActionBar(); 
     actionBar.setDisplayHomeAsUpEnabled(true); 
} 
    Uri uri = getIntent().getData(); 
    Cursor kursor = managedQuery(uri, null, null, null, null); 

    if (kursor == null) { 
     finish(); 
    } else { 
     kursor.moveToFirst(); 

     TextView kata = (TextView) findViewById(R.id.kata); 
     TextView definisi= (TextView) findViewById(R.id.definisi); 

     int wIndex = kursor.getColumnIndexOrThrow(Database.KATA); 
     int dIndex = kursor.getColumnIndexOrThrow(Database.DEFINISI); 

     kata.setText(kursor.getString(wIndex)); 
     definisi.setText(kursor.getString(dIndex)); 
}  } 
@Override 
public boolean onCreateOptionsMenu(Menu menu) { 
    MenuInflater inflater = getMenuInflater(); 
    inflater.inflate(R.menu.main, menu); 

    if(Build.VERSION.SDK_INT >= Build.VERSION_CODES.HONEYCOMB){ 
     SearchManager searchManager = (SearchManager) getSystemService(Context.SEARCH_SERVICE); 
     SearchView searchView = (SearchView) menu.findItem(R.id.search).getActionView(); 
     searchView.setSearchableInfo(searchManager.getSearchableInfo(getComponentName())); 
     searchView.setIconifiedByDefault(false); 
    } 

    return true; 
} 
@Override 
public boolean onOptionsItemSelected(MenuItem item) { 
    switch (item.getItemId()) { 
     case R.id.search: 
      onSearchRequested(); 
      return true; 
     case android.R.id.home: 
      Intent a = new Intent(this, Main.class); 
      a.addFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP); 
      startActivity(a); 
      return true; 
     default: 
      return false; 
    } 
} 
} 

它是一个字典，所以当点击一个列表视图搜索建议，它应该打开definisi.java并显示定义。但是我得到的是当我点击显示main.java的搜索建议时（它只是回到上一个活动）。意图部分有什么问题？请帮我

使用在onNewIntent

protected void onNewIntent(Intent intent) { 
     handleIntent(intent); 
} 

通过intent变量你也应该从handleIntent方法
