在前面有个帖子已经介绍过了。

这里在拿出来用一下，这次用来nocation的图标

RemoteViews contentView = new RemoteViews(context.getPackageName(), R.layout.custom_notification_layout); 
contentView.setImageViewBitmap(R.id.icon_view, myBitmapObject); 
notification.contentView = contentView; 

有时候我们想在listView上分类，或者呢 有时候一行显示两列内容，有时候需要三列内容 ，那怎么实现呢，这里呢就要使用

class Section {
		String caption;
		Adapter adapter;
		
		Section(String caption, Adapter adapter) {
			this.caption=caption;
			this.adapter=adapter;
		}
	}

自定义一个类，这个类呢包含多个adapter就可以了，想用那种就用那种。

abstract public class SectionedAdapter extends BaseAdapter {
	abstract protected View getHeaderView(String caption,int index,View convertView,ViewGroup parent);
	
	private List<Section> sections=new ArrayList<Section>();
	private static int TYPE_SECTION_HEADER=0;

	public SectionedAdapter() {
		super();
	}

	public void addSection(String caption, Adapter adapter) {
		sections.add(new Section(caption, adapter));
	}

	public Object getItem(int position) {
		for (Section section : this.sections) {
			if (position==0) {
				return(section);
			}
			
			int size=section.adapter.getCount()+1;

			if (position<size) {
				return(section.adapter.getItem(position-1));
			}

			position-=size;
		}
		
		return(null);
	}

	public int getCount() {
		int total=0;
		
		for (Section section : this.sections) {
			total+=section.adapter.getCount()+1; // add one for header
		}
		
		return(total);
	}

	public int getViewTypeCount() {
		int total=1;	// one for the header, plus those from sections
		
		for (Section section : this.sections) {
			total+=section.adapter.getViewTypeCount();
		}
		
		return(total);
	}

	public int getItemViewType(int position) {
		int typeOffset=TYPE_SECTION_HEADER+1;	// start counting from here
		
		for (Section section : this.sections) {
			if (position==0) {
				return(TYPE_SECTION_HEADER);
			}
			
			int size=section.adapter.getCount()+1;

			if (position<size) {
				return(typeOffset+section.adapter.getItemViewType(position-1));
			}

			position-=size;
			typeOffset+=section.adapter.getViewTypeCount();
		}
		
		return(-1);
	}

	public boolean areAllItemsSelectable() {
		return(false);
	}

	public boolean isEnabled(int position) {
		return(getItemViewType(position)!=TYPE_SECTION_HEADER);
	}

	@Override
	public View getView(int position, View convertView,
											ViewGroup parent) {
		int sectionIndex=0;
		
		for (Section section : this.sections) {
			if (position==0) {
				return(getHeaderView(section.caption, sectionIndex,convertView, parent));
			}

			int size=section.adapter.getCount()+1;

			if (position<size) {
				return(section.adapter.getView(position-1,	convertView,parent));
			}

			position-=size;
			sectionIndex++;
		}
		
		return(null);
	}

	@Override
	public long getItemId(int position) {
		return(position);
	}

	class Section {
		String caption;
		Adapter adapter;
		
		Section(String caption, Adapter adapter) {
			this.caption=caption;
			this.adapter=adapter;
		}
	}
}

然后主类就是

public class SectionedDemo extends ListActivity {
	private static String[] items={"lorem", "ipsum", "dolor","purus"};
	
	@Override
	public void onCreate(Bundle icicle) {
		super.onCreate(icicle);
		setContentView(R.layout.main);
		
		adapter.addSection("Original",new ArrayAdapter<String>(this,
													android.R.layout.simple_list_item_1,
													items));
		
		List<String> list=Arrays.asList(items);
		
		Collections.shuffle(list);

		adapter.addSection("Shuffled",new ArrayAdapter<String>(this,
													android.R.layout.simple_list_item_1,
													list));
		
		list=Arrays.asList(items);
		
		Collections.shuffle(list);

		adapter.addSection("Re-shuffled",new ArrayAdapter<String>(this,
													android.R.layout.simple_list_item_1,
													list));
		
		setListAdapter(adapter);
	}
	
	SectionedAdapter adapter=new SectionedAdapter() {
		protected View getHeaderView(String caption, int index,View convertView,ViewGroup parent) {
			TextView result=(TextView)convertView;
			
			if (convertView==null) {
				result=(TextView)getLayoutInflater().inflate(R.layout.header, null);
			}
			
			result.setText(caption);
			
			return(result);
		}
	};
}

其他的就需要你自己变化了，我这里只是吧内容打乱。

 有些东西我只是简单调解没有源码或者我认为很简单的就不提供了。

对于复杂一些或者很难说清的 本人表达能力有限会把源码发上的

这里你只要注意ArrayList<HashMap<String,String>> list = new ArrayList<HashMap<String,String>>();的使用就可以了，想要动态添加 这个对象是不能缺少的。

public class CustomList extends ListActivity
{
	ArrayList<HashMap<String,String>> list = new ArrayList<HashMap<String,String>>();
	private static final int ADD_ITEM_ID = 1;

    /** Called when the activity is first created. */
    @Override
    public void onCreate(Bundle icicle)
    {
       super.onCreate(icicle);
       setContentView(R.layout.main);
       notes = new SimpleAdapter( 
				this, 
				list,
				R.layout.main_item_two_line_row,
				new String[] { "line1","line2" },
				new int[] { R.id.text1, R.id.text2 }  );
       setListAdapter( notes );
    }

    @Override
    public boolean onCreateOptionsMenu(Menu menu) {
      boolean result = super.onCreateOptionsMenu(menu);
      menu.add(0, ADD_ITEM_ID, Menu.NONE, R.string.add_item );
      return result;
    }

    @Override
    public boolean onOptionsItemSelected(MenuItem item) {
        switch ( item.getItemId() ) {
          case ADD_ITEM_ID:
				addItem();
                break;
        }
        return super.onOptionsItemSelected(item);
    }

	private void addItem() {
	  long ts = System.currentTimeMillis();
	  int lastDigit = (int)( ts % 10 );
	  HashMap<String,String> item = new HashMap<String,String>();
	  item.put( "line1",Long.toString( ts ) );
	  item.put( "line2","lastDigit: "+Integer.toString( lastDigit ) );
	  list.add( item );
      notes.notifyDataSetChanged();
	}

    private SimpleAdapter notes;
}
