ListActivity with ImageView

Postby darolla » Sat Oct 25, 2008 2:47 pm

Hello,

I tried to develop a CustomList that extends ListActivity.

Right now I am searching for a possibility to add different images to each line.

Who can help me?

Greetings,
Marco

Hello,

my first Idea is to overload the addItem like this:

Syntax: [ Download ] [ Hide ]
Using java Syntax Highlighting
  1.  
  2. public void addItem(List<Map<String,Object>> data, String name, Intent intent, int icon) {
  3.  
  4.         Map<String, Object> temp = new HashMap<String, Object>();
  5.  
  6.         temp.put("title", name);
  7.  
  8.         temp.put("intent", intent);
  9.  
  10.         temp.put("icon", icon);
  11.  
  12.         data.add(temp);
  13.  
  14. }
  15.  
  16.  
Parsed in 0.031 seconds, using GeSHi 1.0.8.4


now I can add my pictures like this:

Syntax: [ Download ] [ Hide ]

  1.  
  2. Intent i = new Intent();
  3.  
  4. i.setClass(CustomList.this, Bets2Activity.class);
  5.  
  6. addItem( list, "Fußball (525)", i, R.drawable.some_picture1 );
  7.  
  8.        
  9.  
  10. i = new Intent();
  11.  
  12. i.setClass(CustomList.this, Bets3Activity.class);
  13.  
  14. addItem( list, "Deutschland (28)", i, R.drawable.some_picture2 );
  15.  
  16.                
  17.  
  18. i = new Intent();
  19.  
  20. i.setClass(CustomList.this, EventsActivity.class);
  21.  
  22. addItem( list, "1. Bundesliga (9)", i, R.drawable.some_picture3 );
  23.  
  24.

Hello,

the last thing should be to alter the Adapter like this:

Syntax: [ Download ] [ Hide ]
Using java Syntax Highlighting
  1.  
  2. SimpleAdapter notes = new SimpleAdapter(this, list,
  3.  
  4.                 R.layout.customlist_item_two_line_row,
  5.  
  6.                 new String[] { "title", "icon" }, new int[] { R.id.text1, R.id.iv });
  7.  
  8. setListAdapter(notes);
  9.  
  10.  
Parsed in 0.035 seconds, using GeSHi 1.0.8.4


And yes, it's working fine :)

Marco

How would you right align the text, so the image and text are on the opposite sides of the row?

that you would do inside this xml

Syntax: [ Download ] [ Hide ]
Using xml Syntax Highlighting
  1. <?xml version="1.0" encoding="utf-8"?>
  2. <LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
  3.     android:layout_width="fill_parent"
  4.     android:layout_height="wrap_content"
  5.     android:orientation="horizontal">
  6.  
  7.      <ImageView android:id="@+id/iv"
  8.          android:layout_width="wrap_content"
  9.          android:layout_height="wrap_content"
  10.          android:src="@drawable/soccer" />
  11.      
  12.      <TextView android:id="@+id/text1"
  13.          android:textSize="16px"
  14.          android:layout_width="fill_parent"
  15.          android:layout_height="fill_parent"
  16.          android:text="Text..."
  17.          android:paddingTop="13px"
  18.          android:paddingLeft="3px" />
