如何实现这个的ListView code中的ImageAdapter？ [英] How to Implement the ImageAdapter for this listView Code?

问题描述

的列表视图code是这样的：

 公共最后静态字符串ITEM_TITLE =称号;
    公共最后静态字符串ITEM_CAPTION =标题
    公共资源的资源;
    公共静态URI路径;
    公共静态文件的文件;
    公共静态ProgressDialog m_progressDialog;
    公共静态的ListView列表;    @覆盖
    公共无效的onCreate（捆绑冰柱）{
        super.onCreate（冰柱）;
        的setContentView（R.layout.main）;        //创建我们的名单和自定义适配器
        SeparatedListAdapter适配器=新SeparatedListAdapter（本）;
        adapter.addSection（本地文件，新ArrayAdapter＆LT;串GT;（这一点，
            R.layout.list_item，新的String [] {WindowsONE手机PK，WindowsorONE成型，菲力汉堡包视频}））;
        adapter.addSection（非本地资源：新ArrayAdapter＆LT;串GT;（这一点，
                R.layout.list_item，新的String [] {启动图片幻灯播放链接，经销商查询链接}））;
        adapter.addSection（发送电子邮件，新ArrayAdapter＆LT;串GT;（这一点，
                R.layout.list_item，新的String [] {发送本地经销商电子邮件，发送邮件目录，发送安装instrucation链接}））;
        //对于列表视图的额外信息
        //adapter.addSection(\"Non-local资源：新SimpleAdapter（这一点，安全，R.layout.list_complex，
        //新的String [] {ITEM_TITLE，ITEM_CAPTION}，新的INT [] {R.id.list_complex_title，R.id.list_complex_caption}））;
        清单= getListView（）;
        list.setAdapter（适配器）;
        list.setTextFilterEnabled（真）;
        list.setOnItemClickListener（本）;
     }}
 

解决方案

 公共类ListContacts扩展ListActivity {ListAdapter lAdapter;@覆盖
    公共无效的onCreate（捆绑savedInstanceState）{
        super.onCreate（savedInstanceState）;
光标光标= getContentResolver（）查询（
                ContactsContract.Contacts.CONTENT_URI，空，
                ContactsContract.Contacts.HAS_PHONE_NUMBER += 1，空，
                UPPER（+ ContactsContract.Contacts.DISPLAY_NAME +）ASC）;        startManagingCursor（光标）;
/ **开始映射* /
        的String [] =列新的String [] {} ContactsContract.Contacts.DISPLAY_NAME;
        INT [] =名新INT [] {} R.id.contact_name;
        lAdapter =新ImageCursorAdapter（这一点，R.layout.contact_listview，
                光标，列名）;
        setListAdapter（lAdapter）;
}公共类ImageCursorAdapter扩展SimpleCursorAdapter{公共ImageCursorAdapter（上下文的背景下，INT布局，光标C，
            的String []从，INT []到）{
        超（背景下，布局，C，从，到）;}* @参数POS
     *：在列表/光标的位置，
     * @参数inView
     *：该行的视图对象，最后创建的，如果空
     *其在第一行
     * @参数父
     *：父视图返回查看的对象的ViewGroup：
     *调用时返回一个视图对象
     * @see android.widget.CursorAdapter＃getView（INT，android.view.View，
     * android.view.ViewGroup）
     * /
    公共查看getView（INT POS，查看inView，父母的ViewGroup）{视图V = inView;}}
 

Code of List View is like:

public final static String ITEM_TITLE = "title";   
    public final static String ITEM_CAPTION = "caption";   
    public Resources resources;
    public static Uri path;
    public static File file;
    public static ProgressDialog  m_progressDialog;
    public static ListView list;

    @Override  
    public void onCreate(Bundle icicle) {   
        super.onCreate(icicle);  
        setContentView(R.layout.main);

        // create our list and custom adapter   
        SeparatedListAdapter adapter = new SeparatedListAdapter(this);   
        adapter.addSection("Local documents:", new ArrayAdapter<String>(this,   
            R.layout.list_item, new String[] { "WindowsONE Mobile PK", "WindowsorONE Moldings","Filet for a burger video" }));
        adapter.addSection("Non-local resources:", new ArrayAdapter<String>(this,   
                R.layout.list_item, new String[] { "Launch Photo slideshow link", "Dealer locator link" }));
        adapter.addSection("Send emails:", new ArrayAdapter<String>(this,   
                R.layout.list_item, new String[] { "Send Dealer Locator email", "Send Catalog email","Send install instrucation link" })); 
        //For extra Information in Listview    
        //adapter.addSection("Non-local resources:", new SimpleAdapter(this, security, R.layout.list_complex,   
        //new String[] { ITEM_TITLE, ITEM_CAPTION }, new int[] { R.id.list_complex_title, R.id.list_complex_caption }));        
        list = getListView();
        list.setAdapter(adapter);   
        list.setTextFilterEnabled(true);
        list.setOnItemClickListener(this); 
     }

}

解决方案

public class ListContacts extends ListActivity {

ListAdapter lAdapter;

@Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);


Cursor cursor = getContentResolver().query(
                ContactsContract.Contacts.CONTENT_URI, null,
                ContactsContract.Contacts.HAS_PHONE_NUMBER + " = 1", null,
                "UPPER(" + ContactsContract.Contacts.DISPLAY_NAME + ") ASC");

        startManagingCursor(cursor);


/** start mapping */
        String[] columns = new String[] { ContactsContract.Contacts.DISPLAY_NAME };
        int[] names = new int[] { R.id.contact_name };
        lAdapter = new ImageCursorAdapter(this, R.layout.contact_listview,
                cursor, columns, names);
        setListAdapter(lAdapter);


}





public class ImageCursorAdapter extends SimpleCursorAdapter

{

public ImageCursorAdapter(Context context, int layout, Cursor c,
            String[] from, int[] to) {
        super(context, layout, c, from, to);

}

* @param pos
     *            : the position in the list/cursor,
     * @param inView
     *            : The View object of the row that was last created, null if
     *            its the first row
     * @param parent
     *            : The ViewGroup object of the parent view return View :
     *            returns a View object when called
     * @see android.widget.CursorAdapter#getView(int, android.view.View,
     *      android.view.ViewGroup)
     */
    public View getView(int pos, View inView, ViewGroup parent) {

View v = inView;

}

}
