與搜索和標記列表

Question

我想實現一個聯繫人列表與搜索和標記功能;除搜索以外的所有內容都正常工我使用的代碼如下。有人能幫我解決這個問題嗎？

public class MainActivity extends ListActivity implements Runnable { 
    Cursor phoneCursor; 
    public static Button done; 
    ListView lv; 
    /* OpenHelper db_obj;*/ 
    final int PROGRESS_DIALOG = 0; 
    ProgressDialog progressDialog; 
    ArrayAdapter<ContactModel> adapter; 
    ArrayList<HashMap<String, String>> CONTACT_DATA = new ArrayList<HashMap<String, String>>(); 

    @Override 
    public void onCreate(Bundle saveinst) { 
     super.onCreate(saveinst); 
     progressDialog=ProgressDialog.show(MainActivity.this, "LoadContacts", "Please wait...", true, false); 
     Thread loadContact = new Thread(this); 
     loadContact.start(); 
    } 

    public void run() { 
     List<ContactModel>contactList = new ArrayList<ContactModel>(); 
     try { 
      Looper.prepare(); 
      Cursor phones = getContentResolver().query(ContactsContract.CommonDataKinds.Phone.CONTENT_URI, null, null, 
                 null, Phone.DISPLAY_NAME + " ASC"); 

      while (phones.moveToNext()) { 
       String name = phones.getString(phones.getColumnIndex(ContactsContract.CommonDataKinds.Phone.DISPLAY_NAME)); 
       String phoneNumber11 = phones.getString(phones.getColumnIndex(ContactsContract.CommonDataKinds.Phone.NUMBER)); 
       contactList.add(get(name,phoneNumber11)); 
      } 
      adapter = new MyContactListAdapter(MainActivity.this, contactList); 
      handler.sendEmptyMessage(0); 
     } catch(Exception exce) { 
      exce.printStackTrace(); 
     } 

     private final Handler handler = new Handler() { 
      @Override 
      public void handleMessage(Message msg) { 
        progressDialog.dismiss(); 
        setListAdapter(adapter); 
        setContentView(R.layout.activity_main); 
        EditText editText; 
        /* db_obj = new OpenHelper(getApplicationContext());*/ 
        lv = getListView(); 
        editText = (EditText)findViewById(R.id.editText1); 
        editText.addTextChangedListener(new TextWatcher() { 
         @Override 
         public void onTextChanged(CharSequence cs, int arg1, int arg2, int arg3) { 
          // When user changed the Text 
          MainActivity.this.adapter.getFilter().filter(cs); 
          setListAdapter(adapter); 
         } 

         @Override 
         public void beforeTextChanged(CharSequence arg0, int arg1, int arg2, 
                 int arg3) { 
          // TODO Auto-generated method stub..... 
         } 

         @Override 
         public void afterTextChanged(Editable arg0) { 
          // TODO Auto-generated method stub 
         } 
        }); 
        done = (Button)findViewById(R.id.button1done); 
        done.setVisibility(View.INVISIBLE); 
        done.setOnClickListener(new View.OnClickListener() { 
         @Override 
         public void onClick(View v) { 
          // TODO Auto-generated method stub 
          MainActivity.this.finish(); 
          Intent in = new Intent(); 
          in.setClass(getApplicationContext(), MainActivity.class); 
          startActivity(in); 
         } 
        }); 
        lv.setOnItemClickListener(new OnItemClickListener() { 
         @Override 
         public void onItemClick(AdapterView<?> arg0, View arg1, int arg2, 
               long arg3) { 
          // TODO Auto-generated method stub 
          System.out.println("Entered List Activity"); 
         } 
        }); 
       } 
      }; 

     public ContactModel get(String name,String number) 
     { 
      return new ContactModel(name,number); 
     }

而不是一個EditText嘗試一個AutoCompleteTextView。它的工作方式類似於你在這裏的，除了搜索由Android處理，而不必在onTextChanged中使用過濾器。

myACTV.setOnTouchListener(new View.OnTouchListener() { 
     @Override 
     public boolean onTouch(View v, MotionEvent event) { 
      // TODO Auto-generated method stub       
      myACTV.showDropDown(); 

      myACTV.setOnItemClickListener(new OnItemClickListener() {     
       @Override 
       public void onItemClick(AdapterView<?> arg0, View arg1, 
         int arg2, long arg3) 
        //Do something here 
       } 

      }); 
      return false; 
     } 

    });
