我如何使用与意图的ListView？ [英] How do I use Intents with ListView?

问题描述

我知道有很多的解决方案来解决这个问题。

I know there are many solutions to solve this problem.

但它不是同一案件作为。

But it's not same case as that.

这是我的Java code。

This is my java code.

package com.progme.sejong_bus;

import android.app.Activity;
import android.os.Bundle;
import android.widget.ArrayAdapter;
import android.widget.ListView;

public class BUSActivity extends Activity {

    ListView listView;

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

        String []data =
            {"공통공지사항","101번 버스정보","102번 버스정보","103번 버스정보","104번 버스정보",
                "105번 버스정보","106번 버스정보","107번 버스정보","108번 버스정보","109번 버스정보",
                "110번 버스정보","111번 버스정보","112번 버스정보","113번 버스정보","114번 버스정보",
                "115번 버스정보","116번 버스정보","117번 버스정보"};

        listView = (ListView)findViewById(R.id.listview1);

        ArrayAdapter<?> adapter = new ArrayAdapter<Object>(getApplicationContext(), android.R.layout.simple_list_item_1, data);

        listView.setAdapter(adapter);
    }
}

这是我的XML code

and this is my XML code

<?xml version="1.0" encoding="UTF-8"?>
<LinearLayout
    xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:orientation="vertical"
    android:background="#000000" >

    <ListView
        android:id="@+id/listview1" 
        android:layout_width="match_parent" 
        android:layout_height="0dp"
        android:layout_gravity="top"
        android:layout_weight="1"
        android:cacheColorHint="#000000"
        android:dividerHeight="1dp"
        android:divider="#FFFFFF" >

    </ListView>

</LinearLayout>

我想意图每个列表..但我怎么能选择每一个列表？

I want intent to each list.. but how can i select each list?

和什么code，我必须使用？

And what code that i have to use?

编辑>

我要见我的应用程序正在这样的形象。

I want to see my app is working like this image.

每个列表链接的每一页。

Each list is link for each page.

和我不能这样做，因为我有code像这样的工作不知道。（？）

And I can't do this because i have no idea with code for to work like this.(?)

反正..我有什么做的？

Anyway.. what I have to do??

推荐答案

所以首先你需要使用一个数组来获取列表项在您当前的电流
字符串[]在你的主Java code =数据可以用这个来代替

SO first you need to use an array to get the list items where your current current string []data= in your main java code can be replaced with this

    // Listview Data
String[] List_items = getResources().getStringArray(R.array.List_items);

创建值一个新的XML文件，并粘贴此code IV刚打电话名单Lise_items
只是无论你在你的列表视图喜欢更换（列表项）

create a new xml file in values and paste this code iv just called the list Lise_items just replace the (list item) with whatever you like in your list view

    <?xml version="1.0" encoding="utf-8"?>
<resources>
    <string-array name="List_items">
<item>list item </item>
<item>list item</item>
<item>list item</item>
<item>list item</item>
<item>list item</item>
</string-array>
</resources>

通过添加的onclick监听器

by added the onclick listener

/// listening to single list item on click

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

          /// selected item 

          String List_items = ((TextView) view).getText().toString();

          /// Launching new Activity on selecting single List Item

          Intent i = new Intent(getApplicationContext(), SingleListItem.class);
          /// sending data to new activity
          i.putExtra("List_items", List_items);
          startActivity(i);

      }
    });
}

}

您将需要创建在单击查看

You will need to create another xml file and java file for the view on click

例如：

list_item_view.xml

        <?xml version="1.0" encoding="utf-8"?>
        <LinearLayout
          xmlns:android="http://schemas.android.com/apk/res/android"
          android:orientation="vertical"
          android:layout_width="match_parent"
          android:layout_height="match_parent">

    <TextView android:id="@+id/List_item"
                    android:layout_width="fill_parent"
                    android:layout_height="wrap_content"
                    android:textSize="25dip"
                    android:textStyle="bold"
                    android:padding="10dip"
                    android:textColor="#ffffff"/>    
        </LinearLayout>

Listitemselected.java

        package com.progme.sejong_bus;

    import android.app.Activity;
    import android.content.Intent;
    import android.os.Bundle;
    import android.widget.TextView;


        public class Listitemselected extends Activity{
            @Override
            public void onCreate(Bundle savedInstanceState) {
                super.onCreate(savedInstanceState);
                this.setContentView(R.layout.list_item_view);

                TextView txtList_items = (TextView) findViewById(R.id.List_items);

                Intent i = getIntent();

                // getting attached intent data

                String List_items = i.getStringExtra("List_items");

 // displaying selected List name
                txtList_items.setText(List_items);

            }
        }

您必须创建因为这是在这么当每个项目点击它会去例如：

You will have to create a new intent for each item that is in the list so when each item is clicked it will go to a new activity for example

  protected void onListItemClick(ListView l, View v, int position, long id) {
    // TODO Auto-generated method stub
    super.onListItemClick(l, v, position, id); 

    Intent a;
     switch(position){

    case 1:
        a = new Intent("Items 1 page");
        break;
     case 2:
       a  = new Intent("items 2 page");
       break;

    if(null!=a)
    startActivity(a);
 }

}
