Android SearchView小工具僅適用於啓動器活動

Question

我現在正面臨一個非常奇怪的錯誤。基本上，該應用可以使用SearchView小部件搜索Google Places API，並在Google Maps Android API V2中顯示結果，並將searchview小部件放置在操作欄中。我參考了本教程： http://wptrafficanalyzer.in/blog/android-searchview-widget-with-google-places-api-using-actionbarsherlock-library/

當可搜索活動（我將其命名爲SearchPlace）是主要和啓動器活動時，該應用正常工作。但是，如果我嘗試從其他活動中進行此活動，則應用程序崩潰。我得到了由handleIntent（）引起的NullPointerException。 我附上了SearchPlace下面的Manifest文件的一部分，是我的可搜索活動的名稱。

錯誤日誌附在下面。看起來像我的handleIntent（）導致了錯誤。

我SearchPlace活動

@Override 
protected void onCreate(Bundle savedInstanceState) 
{ 

    super.onCreate(savedInstanceState); 
    setContentView(R.layout.google_map_v2); 

    handleIntent(getIntent()); 

} 

private void handleIntent(Intent intent) 
{ 
    if(intent.getAction().equals(Intent.ACTION_SEARCH)) 
    { 
     doSearch(intent.getStringExtra(SearchManager.QUERY)); 
    } 
    else if(intent.getAction().equals(Intent.ACTION_VIEW)) 
    { 
     getPlace(intent.getStringExtra(SearchManager.EXTRA_DATA_KEY)); 
    } 
} 

@Override 
protected void onNewIntent(Intent intent) 
{ 
    super.onNewIntent(intent); 
    setIntent(intent); 
    handleIntent(intent); 
} 

private void doSearch(String query) 
{ 
    Bundle data = new Bundle(); 
    data.putString("query", query); 
    getSupportLoaderManager().restartLoader(0, data, this); 
} 

private void getPlace(String query) 
{ 
    Bundle data = new Bundle(); 
    data.putString("query", query); 
    getSupportLoaderManager().restartLoader(1, data, this); 
} 

@Override 
public Loader<Cursor> onCreateLoader(int arg0, Bundle query) 
{ 
    CursorLoader cLoader = null; 
    if(arg0 == 0) 
     cLoader = new CursorLoader(getBaseContext(), 
       PlaceProvider.SEARCH_URI, null, null, new String[] 
       { query.getString("query") }, null); 
    else if(arg0 == 1) 
     cLoader = new CursorLoader(getBaseContext(), 
       PlaceProvider.DETAILS_URI, null, null, new String[] 
       { query.getString("query") }, null); 
    return cLoader; 

} 

@Override 
public void onLoadFinished(Loader<Cursor> arg0, Cursor c) 
{ 
    showLocations(c); 

} 

@Override 
public void onLoaderReset(Loader<Cursor> arg0) 
{ 
    // TODO Auto-generated method stub 
} 

誰能幫我PLZ？

謝謝

問題解決了，修改handleIntent（）作爲

if(Intent.ACTION_SEARCH.equals(intent.getAction())) 
{ 
String query = intent.getStringExtra(SearchManager.QUERY); 
doSearch(query); 
} 
else if(Intent.ACTION_VIEW.equals(intent.getAction())) 
{ 
getPlace(intent.getStringExtra(SearchManager.EXTRA_DATA_KEY)); 
}
