添加日期和時間RSS飼料 - Android

Question

我有一個rss飼料與3個選項卡，每個選項卡從鏈接提取rss。 rss正常工作，但我想在pictureLINK的這部分的每個Feed中添加DATE和TIME，並使其像這樣pictureLINK。任何人都可以幫助我。

這裏是我的全碼：

RssTabsActivity.java

public class RssTabsActivity extends TabActivity { 


@Override 
protected void onCreate(Bundle savedInstanceState) { 
    super.onCreate(savedInstanceState); 
    setContentView(R.layout.activity_rss_tabs); 
    TabHost tabHost = getTabHost(); 
    Intent artIntent = new Intent().setClass(this, RssChannelActivity.class); 
    artIntent.putExtra("rss-url", "http://www1.up.edu.ph/index.php/feed/"); 
    String artTabName = getResources().getString(R.string.tab_art); 
    TabSpec artTabSpec = tabHost.newTabSpec(artTabName) 

.setIndicator(artTabName, getResources().getDrawable(R.drawable.rss_tab_art)) 

.setContent(artIntent); 
    tabHost.addTab(artTabSpec); 
    Intent techIntent = new Intent().setClass(this, RssChannelActivity.class); 
    techIntent.putExtra("rss-url", "http://www1.up.edu.ph/index.php/feed/"); 
    String techTabName = getResources().getString(R.string.tab_tech); 
    TabSpec techTabSpec = tabHost.newTabSpec(techTabName) 

.setIndicator(techTabName, getResources().getDrawable(R.drawable.rss_tab_tech)) 

.setContent(techIntent); 
    tabHost.addTab(techTabSpec); 
    Intent sportsIntent = new Intent().setClass(this, RssChannelActivity.class); 
    sportsIntent.putExtra("rss-url", "http://www1.up.edu.ph/index.php/feed/"); 
    String sportsTabName = getResources().getString(R.string.tab_sports); 
    TabSpec sportsTabSpec = tabHost.newTabSpec(sportsTabName) 

.setIndicator(sportsTabName, getResources().getDrawable(R.drawable.rss_tab_sports))

RssReader.java

您需要創建自定義ArrayAdapter：

public class CustomArrayAdapter extends ArrayAdapter<RssItem> { 

    private final List<RssItem> aListItems 
    private final Activity context; 

    public InteractiveArrayAdapter(Activity context, List<RssItem> aListItems) { 
    super(context, R.layout.yourcustomlayout, aListItems); 
    this.context = context; 
    this.aListItems = aListItems; 
    } 

    @Override 
    public View getView(int position, View convertView, ViewGroup parent) { 
    View view = null; 
    if (convertView == null) { 
     LayoutInflater inflator = context.getLayoutInflater(); 
     view = inflator.inflate(R.layout.yourcustomlayout, null); 
     final ViewHolder viewHolder = new ViewHolder(); 
     viewHolder.text = (TextView) view.findViewById(R.id.title); 
     viewHolder.time = (TextView) view.findViewById(R.id.time); 
     view.setTag(viewHolder); 
    } else { 
     view = convertView; 
    } 
    ViewHolder holder = (ViewHolder) view.getTag(); 
    holder.text.setText(aListItems.get(position).getName()); 
    holder.time.setText(aListItems.get(position).getTime()); 
    return view; 
    } 


    static class ViewHolder { 
    protected TextView text; 
    protected TextView time; 
    } 
} 

您的自定義XML：

<?xml version="1.0" encoding="utf-8"?> 
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android" 
android:layout_width="match_parent" 
android:layout_height="wrap_content" > 
<TextView 
    android:id="@+id/title" 
    android:layout_width="wrap_content" 
    android:layout_height="wrap_content" 
    android:text="@+id/title" 
    android:textSize="30px" > 
</TextView> 

<TextView 
    android:id="@+id/time" 
    android:layout_width="wrap_content" 
    android:layout_height="wrap_content" 
    android:text="@+id/time" 
    android:textSize="30px" > 
</TextView>
