你沒有在GetContactAdapter中出現任何錯誤嗎?因爲您沒有重寫Filterable的任何方法? – Raghavendra

試試這個代碼,如果它可以幫助你

public class SearchViewFilterMode extends Activity implements SearchView.OnQueryTextListener { 

    private SearchView mSearchView; 
    private ListView mListView; 

    private final String[] mStrings = Cheeses.sCheeseStrings; 

    @Override 
    protected void onCreate(Bundle savedInstanceState) { 
     super.onCreate(savedInstanceState); 
     getWindow().requestFeature(Window.FEATURE_ACTION_BAR); 

     setContentView(R.layout.searchview_filter); 

     mSearchView = (SearchView) findViewById(R.id.search_view); 
     mListView = (ListView) findViewById(R.id.list_view); 
     mListView.setAdapter(new ArrayAdapter<String>(this, 
       android.R.layout.simple_list_item_1, 
       mStrings)); 
     mListView.setTextFilterEnabled(true); 
     setupSearchView(); 
    } 

    private void setupSearchView() { 
     mSearchView.setIconifiedByDefault(false); 
     mSearchView.setOnQueryTextListener(this); 
     mSearchView.setSubmitButtonEnabled(true); 
     mSearchView.setQueryHint("Search Here"); 
    } 

    public boolean onQueryTextChange(String newText) { 
     if (TextUtils.isEmpty(newText)) { 
      mListView.clearTextFilter(); 
     } else { 
      mListView.setFilterText(newText.toString()); 
     } 
     return true; 
    } 

    public boolean onQueryTextSubmit(String query) { 
     return false; 
    } 
}

請向作者解釋如何將解決。隨着代碼發佈一些說明? – Raghavendra
