Clicking on the listview it has to go their respective activity?

Question

I have one ListView. It contains text with images. I know that if I click the ListView item a Toast will appear, but what I want is for a click on the item to open their respective activity.

 @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;
        }

What I want is if I click the first image it has to go their Activity. Like that it has to go their respective activity, not a same one. How can I do this?

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

you can use intent in onClickListener

like

    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);
        }  
    });

You can use Switch or if else statement inside onClick to go to perticular activites according to clicked position

like

   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;

So on.....

no i know that one,if i clicked all the image it will goes to the second activity,but what i need is if i click the first text it has to go second activity,if i click the second text it has to go third activity like this i want – kkarthickk Mar 05 '13 at 10:29
Dude,i didn't get ur answer correctly,first i will explain clearly,having 5 items in the list view,if i click the first item it has to open firstactivity,and next if i click the second item it has to open second and if i click 3 items it has to open 3 activity like that i want. – kkarthickk Mar 05 '13 at 10:51
ya thats what i have written in my answer Array is ur list view items which are you displaying in list (take your specified name for that)ok and in onClickListener Array[position] will give you clicked item position and according to that position open your relative activity like if position 2 is clicked Array[2] and Case 2 will open your activity specified in that – Shiv Mar 05 '13 at 11:00
Array[2] is the item you clicked at position 2 use case "item at 2nd position": //open 2nd activity – Shiv Mar 05 '13 at 11:05

use switch-case to open Activity according to ListView click as :

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
        }
       }  
  });

Looking at your logcat output there is problem in androidmenifest file, app is unable to find activity class. You should change declaration of activity.

From:

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

To:

<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>

Note: there is missing . in declaration of activity

i changed my jdk version as 1.7 also,eventhough it showing error in that line switch(obj_itemDetails.getName()) – kkarthickk Mar 05 '13 at 12:14

Like logcat says, error is on your manifest file..You are not registered the activity properly. In your manifest add "." before all activity name like this

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

or you have to specify like this

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

You need to edit each one.

Clicking on the listview it has to go their respective activity?
