点击的列表视图它必须去各自的活动？

我有一个ListView。它包含带图像的文字。我知道如果我点击ListView项目，Toast会出现，但我想要的是点击该项目以打开其各自的活动。点击的列表视图它必须去各自的活动？

@Override 
     public void onCreate(Bundle savedInstanceState) { 
      super.onCreate(savedInstanceState); 
      setContentView(R.layout.main); 

      ArrayList<Recipedetails> image_details = GetSearchResults(); 

      final ListView lv1 = (ListView) findViewById(R.id.listV_main); 
      lv1.setAdapter(new ItemListBaseAdapter(this, image_details)); 

      lv1.setOnItemClickListener(new OnItemClickListener() { 
       @Override 
       public void onItemClick(AdapterView<?> a, View v, int position, long id) { 
        Object o = lv1.getItemAtPosition(position); 
        Recipedetails obj_itemDetails = (Recipedetails)o; 
        Toast.makeText(SouthIndian.this, "You have chosen : " + " " + obj_itemDetails.getName(), Toast.LENGTH_LONG).show(); 

        switch(obj_itemDetails.getName()) 
        { 
        case "Vegterian": 
         Intent newActivity = new Intent(SouthIndian.this, 
                SouthIndianvegrecipes.class);  
         startActivity(newActivity); 
         break; 
        case "Non-Vegterian": 
         Intent new1Activity = new Intent(SouthIndian.this, 
           SouthIndiannonvegrecipes.class);  
         startActivity(new1Activity); 
         break; 
        //same for other Activity 
        } 
       } 
      }); 
     } 

     private ArrayList<Recipedetails> GetSearchResults(){ 
      ArrayList<Recipedetails> results = new ArrayList<Recipedetails>(); 

      Recipedetails item_details = new Recipedetails(); 
      item_details.setName("Vegterian"); 
      item_details.setItemDescription("Recipes made by raw materials"); 
      //item_details.setPrice("RS 310.00"); 
      item_details.setImageNumber(1); 
      results.add(item_details); 

      item_details = new Recipedetails(); 
      item_details.setName("Non-Vegterian"); 
      item_details.setItemDescription("Flesh of sweet animals"); 
      //item_details.setPrice("RS 350.00"); 
      item_details.setImageNumber(2); 
      results.add(item_details); 

      item_details = new Recipedetails(); 
      item_details.setName("Pickels"); 
      item_details.setItemDescription("Touchable dish by Homemade"); 
      //item_details.setPrice("RS 250.00"); 
      item_details.setImageNumber(3); 
      results.add(item_details); 

      item_details = new Recipedetails(); 
      item_details.setName("Soups"); 
      item_details.setItemDescription("Startup for our food"); 
      //item_details.setPrice("RS 350.00"); 
      item_details.setImageNumber(4); 
      results.add(item_details); 




      return results; 
     }

我想要的是如果我点击第一个图像，它必须去Activity。就像它必须去各自的活动一样，不是一回事。我怎样才能做到这一点？

我的AndroidManifest.xml

<activity 
     android:name="com.example.recipestutors.MainActivity" 
     android:label="@string/app_name" > 
     <intent-filter> 
      <action android:name="android.intent.action.MAIN" /> 

      <category android:name="android.intent.category.LAUNCHER" /> 
     </intent-filter> 
    </activity> 

    <activity android:name="RecipeActivity" android:label="@string/activity_recipeview" android:theme="@style/AppTheme"></activity> 
    <activity android:name="SouthIndian" android:label="@string/activity_SouthIndianrecipeview" android:theme="@style/AppTheme"></activity> 
    <activity android:name="NorthIndian" android:label="@string/activity_NorthIndianrecipeview" android:theme="@style/AppTheme"></activity> 
    <activity android:name="Western" android:label="@string/activity_Westernrecipeview" android:theme="@style/AppTheme"></activity>

    <activity android:name="SouthIndiannonvegrecipes" android:label="@string/activity_Chineserecipeview" android:theme="@style/AppTheme"></activity> 
</application>

你可以使用意图在onClickListener

像

lv1.setOnItemClickListener(new OnItemClickListener() { 
     @Override 
     public void onItemClick(AdapterView<?> a, View v, int position, long id) { 
      Intent intent = new Intent(firstActivity.this, SecondActivity.class); 

      startActivity(intent); 
     } 
    });

您可以使用开关或如果里面的onClick else语句去perticular activites根据点击位置

像

switch (Array[position]) { 

    case Array[1]: //if position1 is clicked 
      Intent intent = new Intent(MainActivity.this, FirstActivity.class); 

      startActivity(intent); 
      break; 
      case Array[2]: //if 2nd position is clicked..so on 
      Intent intent = new Intent(MainActivity.this, SecondActivity.class); 

      startActivity(intent); 
      break;

等等.....

没有，我知道那一个，如果我点击所有的图像也将进入到第二个活动，但如果我点击它已去第二个活动，第一个文本，如果我点击它有第二个文本我需要的是去第三个活动，像这样我想 – kkarthickk 2013-03-05 10:29:58

看到编辑答案] – Shiv 2013-03-05 10:36:18

老兄，我没有得到你的回答正确，首先我会解释清楚，有5个项目在列表视图中，如果我点击第一个项目它必须打开firstactivity，接下来如果我点击第二个项目它必须打开第二个，如果我点击3个项目，它必须打开3个活动，就像我想要的。 – kkarthickk 2013-03-05 10:51:51

使用switch-case打开活动根据ListView的点击为：

lv1.setOnItemClickListener(new OnItemClickListener() { 
    @Override 
    public void onItemClick(AdapterView<?> a, View v, int position, long id) { 
     Object o = lv1.getItemAtPosition(position); 
     Recipedetails obj_itemDetails = (Recipedetails)o; 
     Toast.makeText(SouthIndian.this, "You have chosen : " + " " + 
          obj_itemDetails.getName(), Toast.LENGTH_LONG).show(); 
      switch(obj_itemDetails.getName()) 
      { 
      case "Vegterian": 
       Intent newActivity = new Intent(SouthIndian.this, 
              Vegterian_Activity.class);  
       startActivity(newActivity); 
      break; 
      case "Non-Vegterian": 
       Intent newActivity = new Intent(SouthIndian.this, 
             Non_Vegterian_Activity.class);  
       startActivity(newActivity); 
      break; 
      .....//same for other Activity 
     } 
     } 
    });

感谢花花公子我会检查，并告诉 – kkarthickk 2013-03-05 10:36:18

十月3日至5日：41：29.611：E/AndroidRuntime（3334）：了java.lang.RuntimeException：无法实例活动ComponentInfo {融为一体。 example.recipestutors/com.example.recipestutors.MainActivity}：java.lang.ClassNotFoundException：未在路径中找到类“com.example.recipestutors.MainActivity”：/data/app/com.exa mple.recipestutors-1.apk 10月3日至5日：41：29.611：E/AndroidRuntime（3334）：抛出java.lang.ClassNotFoundException：由造成没有对路径发现类 “com.example.recipestutors.MainActivity”： /data/app/com.example.recipestutors-1.apk 它显示logcat中的错误 – kkarthickk 2013-03-05 10:52:31

@ user2118898：请确保您已添加AndroidManifest.xml中的所有活动。还要检查MainActivity活动 – 2013-03-05 10:55:23

看着你的logcat输出在androidmenifest文件中有问题，应用程序无法找到活动类。你应该改变活动的声明。

来源：

<activity android:name="RecipeActivity" android:label="@string/activity_recipeview" android:theme="@style/AppTheme"></activity>

要：

<activity android:name=".RecipeActivity" android:label="@string/activity_recipeview" android:theme="@style/AppTheme"></activity>

OR：

<activity android:name="FULL_PACKAGE_PATH.RecipeActivity" android:label="@string/activity_recipeview" android:theme="@style/AppTheme"></activity>

注：有缺失。在活动宣言

我做到了，但现在显示错误，Android需要编译器合规性级别5.0或6.0。取而代之的是“1.7”。请使用Android工具>修复项目属性。 – kkarthickk 2013-03-05 12:13:01

我改变了我的JDK版本为1.7也，尽管它显示该行开关错误（obj_itemDetails.getName（）） – kkarthickk 2013-03-05 12:14:35

老兄我们不能在开关中使用字符串，我怎么写 – kkarthickk 2013-03-05 12:29:47

就像logcat说，错误是在你的清单文件..你没有正确注册的活动。在您的清单中添加“。”你必须指定这样

<activity android:name="com.example.recipestutors.RecipeActivity" android:label="@string/activity_recipeview" android:theme="@style/AppTheme"></activity>

这样

<activity android:name=".RecipeActivity" android:label="@string/activity_recipeview" android:theme="@style/AppTheme"></activity>

所有活动名称前或你需要编辑每一个。
