如何在過濾器ListView- Item-Click上加載特定的活動（多重意圖）？

沒有錯誤，但是當我點擊一個listview項時什麼也沒有發生。我有超過10個項目。並去差異化的活動。任何想法？我也是Eclipse的初學者也是java。如何在過濾器ListView- Item-Click上加載特定的活動（多重意圖）？

例子： 1.Niat（ListView控件-OnItemClickListener）會去NiatActivity.class 2.Lafaz（ListView控件-OnItemClickListener）會去LafazActivity.class

這裏我的代碼。提前致謝。

import java.util.ArrayList; 
import java.util.HashMap; 

import android.app.Activity; 
import android.content.Intent; 
import android.os.Bundle; 
import android.text.Editable; 
import android.text.TextWatcher; 
import android.view.View; 
import android.view.View.OnClickListener; 
import android.widget.AdapterView; 
import android.widget.AdapterView.OnItemClickListener; 
import android.widget.ArrayAdapter; 
import android.widget.EditText; 
import android.widget.ListView; 
import android.widget.TextView; 

public class MainTwoActivity extends Activity { 

    // List view 
    private ListView lv; 

    // Listview Adapter 
    ArrayAdapter<String> adapter; 

    // Search EditText 
    EditText inputSearch; 

    // ArrayList for Listview 
    ArrayList<HashMap<String, String>> productList; 

    @Override 
    protected void onCreate(Bundle savedInstanceState) { 
     super.onCreate(savedInstanceState); 
     setContentView(R.layout.activity_main_two); 

     // Listview Data 
     final String products[] = { "Niat", 
       "Lafaz", "Solat" }; 

     lv = (ListView) findViewById(R.id.list_view); 

     inputSearch = (EditText) findViewById(R.id.inputSearch); 

     // Adding items to listview 
     adapter = new ArrayAdapter<String>(this, R.layout.list_item, 
       R.id.product_name, products); 
     lv.setAdapter(adapter); 

     /** 
     * Enabling Search Filter 
     * */ 

     inputSearch.addTextChangedListener(new TextWatcher() { 

      @Override 
      public void onTextChanged(CharSequence cs, int arg1, int arg2, 
        int arg3) { 
       // When user changed the Text 
       MainTwoActivity.this.adapter.getFilter().filter(cs); 
      } 

      @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 
      } 

     }); 

     lv.setOnItemClickListener(new OnItemClickListener() { 

      public void onItemClick(AdapterView<?> parent, View view, 
        int position, long id) { 
       // if(position == 1) 
       String openClass = adapter.getItem(position); 
       if (openClass.equals("Niat")) { 
        // code specific to first list item 
        Intent myIntent = new Intent(view.getContext(), 
          NiatActivity.class); 
        startActivity(myIntent); 
       } 

       else if (openClass.equals("Lafaz")) { 
        Intent myIntent1 = new Intent(view.getContext(), 
       LafazActivity.class); 
        startActivity(myIntent1); 

       } 
      } 

     }); 

    } 
}

使用Java反射使用http://tutorials.jenkov.com/java-reflection/dynamic-class -loading-reloading.html – SelvaMariappan 2014-12-04 09:57:57

如果您想要在列表項上點擊不同的活動，只需使用Switch語句獲取其位置。 – Piyush 2014-12-04 10:36:05

@PiyushGupta已經切換語句，但仍然不工作 – malona 2014-12-05 05:52:09

使用反射是更好，但也ü可以使用的HashMap HashMap的

HashMap<String, Class>hashMap=new HashMap<String, Class>(); 


    hashMap.put("Niat",NiatActivity.class); 
    hashMap.put("Lafaz",LafazActivity.class); 
    hashMap.put("Solat",SolatActivity.class); 
    lv.setOnItemClickListener(new OnItemClickListener() { 

     public void onItemClick(AdapterView<?> parent, View view, 
       int position, long id) { 
    String openClass = adapter.getItem(position); 
    Intent myIntent1 = new Intent(MainTwoActivity.this, 
       hashMap.get(openClass)); 
      startActivity(myIntent1); 
    }

這工作正常！謝謝。 – malona 2014-12-05 05:50:58

MaWhen開始一個新的活動，你應該使用

Intent myIntent = new Intent(MainTwoActivity.this ,NiatActivity.class);

查看的getContext（）犯規攜帶您的應用程序的完整環境。讀了here
