无法建立的Andr​​oid onListItemClick方法 [英] Can't create android onListItemClick method

问题描述

现在，我想创建一个Android onListItemClick方法。但每次我这样做时得到吨语法错误说法预期分号。通常，当我得到语法错误一样，我知道只需添加一个分号，但在这种情况下我不知道分号应该如何被应用到这样的事情。是否有甚至应该在第一个地方这样的说法半冒号？这里是code

 包net.androidbootcamp.coffeefinder;进口的java.util.Calendar;进口android.os.Bundle;
进口android.app.Activity;
进口android.app.ListActivity;
进口android.view.Menu;
进口android.view.View;
进口android.widget.ArrayAdapter;
进口android.widget.ListView;公共类MainActivity扩展ListActivity {    @覆盖
    保护无效的onCreate（捆绑savedInstanceState）{
        super.onCreate（savedInstanceState）;
        的setContentView（R.layout.activity_main）;
        //菜单选择阵列
        的String [] = CoffeeShop咖啡{创世，星巴克，驯鹿，Mo'Joe};
        //设置列表适配器列表
        setListAdapter（新ArrayAdapter＆LT;串GT;（这一点，R.layout.activity_main，R.id.C​​offee，CoffeeShop咖啡））;
        //创建列表的行为        保护无效onListItemClick（ListView中升，视图V，INT位置，长的ID）
        {        }
 

解决方案

应该走你的onCreate外：

 公共类MainActivity扩展ListActivity {    @覆盖
    保护无效的onCreate（捆绑savedInstanceState）{
        super.onCreate（savedInstanceState）;
        的setContentView（R.layout.activity_main）;
        //菜单选择阵列
        的String [] = CoffeeShop咖啡{创世，星巴克，驯鹿，Mo'Joe};
        //设置列表适配器列表
        setListAdapter（新ArrayAdapter＆LT;串GT;（这一点，R.layout.activity_main，R.id.C​​offee，CoffeeShop咖啡））;
        //创建列表的行为
    }    保护无效onListItemClick（ListView中升，视图V，INT位置，长的ID）
    {    }}
 

Right now I'm trying to create an android onListItemClick method. But every time I do it get tons of syntax errors saying expected semicolon. Normally when I get syntax errors like that I know to just add a semi-colon but in this situation I have no clue how semi-colons are supposed to be applied to a thing like that. Is there even supposed to be semi colons in such a statement in the first place? Here is the code

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)
        {

        } 

解决方案

It should go outside your 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)
    {

    } 

}
