please I'm trying to add understand how to add onItemClickListener to the followng code such that when "Smartphone Plans" is clicked, its activity starts and so on. I've seen other questions on StackOverflow relating to this question but do not understand how to go about them. I've already added an onItemClickListener but do not understand how to set it to specific list items. here is the code

package devchuks.com.rechargeit;

import android.support.v7.app.AppCompatActivity;
import android.os.Bundle;
import android.view.View;
import android.widget.AdapterView;
import android.widget.ArrayAdapter;
import android.app.ListActivity;

import android.widget.ListView;
import android.widget.TextView;
import android.widget.Toast;
import android.widget.AdapterView.OnItemClickListener;

public class EtisalatData extends AppCompatActivity {
    ListView listView;

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

        listView = (ListView) findViewById(R.id.list);


        String[] values = new String[] {
                "Smartphone Plans",
                "Internet Bundles",
                "Weekend Plans",

        };



        ArrayAdapter<String> adapter = new ArrayAdapter<String>(this,
                android.R.layout.simple_list_item_1, android.R.id.text1, values);



        listView.setAdapter(adapter);


        listView.setOnItemClickListener(new OnItemClickListener() {

            @Override
            public void onItemClick(AdapterView<?> parent, View view,
                                    int position, long id) {


            }

        });
    }

}

推荐答案

您可以像这样定义您的 listView.setOnItemClickListener 进入不同的活动，以单击不同的元素.

You can define your listView.setOnItemClickListener like this to go to different activity for clicking different element.

listView.setOnItemClickListener(new OnItemClickListener() {

    @Override
    public void onItemClick(AdapterView<?> parent, View view,
                            int position, long id) {
         String item = listView.getItemAtPosition(position);
         Toast.makeText(this,"You selected : " + item,Toast.LENGTH_SHORT).show();
         if(position==0) {
            // Do your code for clicking "Smartphone Plans" example
            // startActivity(new Intent(getApplicationContext(),SmartphonePlans.class));
         }
        else if(position==1) { 
           // Do your code for clicking "Internet Bundles". example
          // startActivity(new Intent(getApplicationContext(),InternetBundles.class));
         }
        else if(position==2) { 
           // Do your code for clicking "Weekend Plans". example 
          //startActivity(new Intent(getApplicationContext(),WeekendPlans.class));*/
    }

});
