Question

现在我正在尝试创建一个android onListItemClick方法。但是每次我这样做都会有大量的语法错误，说明了预期的分号。通常情况下，当我得到语法错误时，我知道只需添加一个分号，但在这种情况下，我不知道如何将半冒号应用于类似的东西。首先在这样的声明中是否应该是半冒号？这是代码

package net.androidbootcamp.coffeefinder;

import java.util.Calendar;

import android.os.Bundle;
import android.app.Activity;
import android.app.ListActivity;
import android.view.Menu;
import android.view.View;
import android.widget.ArrayAdapter;
import android.widget.ListView;

public class MainActivity extends ListActivity {

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
        //Menu Select Array
        String[] CoffeeShop = {"Creation","Starbucks","Caribou","Mo'Joe" };
        //Set list adapter for list
        setListAdapter(new ArrayAdapter<String>(this,R.layout.activity_main,R.id.Coffee,CoffeeShop));
        //Create actions of list

        protected void onListItemClick(ListView l, View v, int position, long id)
        {

        }

Answer 1

它应该超出你的onCreate：

public class MainActivity extends ListActivity {

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
        //Menu Select Array
        String[] CoffeeShop = {"Creation","Starbucks","Caribou","Mo'Joe" };
        //Set list adapter for list
        setListAdapter(new ArrayAdapter<String>(this,R.layout.activity_main,R.id.Coffee,CoffeeShop));
        //Create actions of list
    }

    protected void onListItemClick(ListView l, View v, int position, long id)
    {

    } 

}

Answer 2

这个方法应该是onCreate（）：

lv.setOnItemClickListener(new OnItemClickListener() {
          public void onItemClick(AdapterView<?> parent, View view,
              int position, long id) {

              // selected item will be in position
              //do what ever you want to do.

          }
        });
