sencha touch2学习笔记(五)----Carousel 可滑动换页

Carousel是一个可以滑动的组件，就如android的ViewFlipper。只是Carousel更好看。

代码如下：

 

Ext.application(
{
	name:"sencha",
	launch:function()
	{
		
		Ext.create(
		"Ext.Carousel",
		{
			fullscreen:true,
			direction: 'vertical',
			defaults: {
		        styleHtmlContent: true
		    },
			items:[
			{
				xtype:"list",
				items:[
				{
					xtype:"toolbar",
					dock:"top",
					title:"列表哦"
				}
				],
				store:
				{
					fields:["name"],
					data:[
					{name:"陈乃共"}
					]
				},
				itemTpl:'name'
				
			},
			{
				html:"html1",
				style:"background-color:#00FF00"
			},
			{
				html:"html1",
				style:"background-color:#0000FF"
			}
			]
		}
		)
		
	}
}
)

Drawable, Bitmap和byte[]的转换

android在处理一写图片资源的时候，会进行一些类型的转换，现在有空整理一下：

1、Drawable → Bitmap
Java代码 
public static Bitmap drawableToBitmap(Drawable drawable) { 
         
        Bitmap bitmap = Bitmap 
                        .createBitmap( 
                                        drawable.getIntrinsicWidth(), 
                                        drawable.getIntrinsicHeight(), 
                                        drawable.getOpacity() != PixelFormat.OPAQUE ? Bitmap.Config.ARGB_8888 
                                                        : Bitmap.Config.RGB_565); 
        Canvas canvas = new Canvas(bitmap); 
        //canvas.setBitmap(bitmap); 
        drawable.setBounds(0, 0, drawable.getIntrinsicWidth(), drawable.getIntrinsicHeight()); 
        drawable.draw(canvas); 
        return bitmap; 
} 

2、从资源中获取Bitmap

Java代码 
Resources res=getResources(); 
 
Bitmap bmp=BitmapFactory.decodeResource(res, R.drawable.pic); 

3、Bitmap → byte[]

Java代码 
private byte[] Bitmap2Bytes(Bitmap bm){ 
    ByteArrayOutputStream baos = new ByteArrayOutputStream();   
    bm.compress(Bitmap.CompressFormat.PNG, 100, baos);   
    return baos.toByteArray(); 
   } 

4、 byte[] → Bitmap
Java代码 
private Bitmap Bytes2Bimap(byte[] b){ 
            if(b.length!=0){ 
                return BitmapFactory.decodeByteArray(b, 0, b.length); 
            } 
            else { 
                return null; 
            } 
      }
