山寨之旅[一]山寨Funambol UI一点点

代码图片布局创意等等所有的一切都归原创者所有
我已经分不清谁是原创
如要用于商业，请遵守相关法则

主要的代码就是SyncStatusPanel.java
山寨的还不够干净利落，有些代码可能无用

}

这个类代码很少，但是还是可以学到些基本知识

比如为什么要用Runnable来更新UI

adaptSizeToDensity方法的目的

用XML来定义背景图形

RelativeLayout基本知识

等等等等

调用方法如下：

		LinearLayout lll = (LinearLayout) findViewById(R.id.boxes);

		LinearLayout.LayoutParams ll1Params = new LinearLayout.LayoutParams(
				LayoutParams.FILL_PARENT,
				LayoutParams.FILL_PARENT);

		SyncStatusPanel ssp = new SyncStatusPanel(this); // 这个是我们自定义的

		ssp.setIcon(R.drawable.icon_calendar);
		ssp.setTitle("日程安排");
		ssp.setStatusString("上次同步在 2010-01-01 12:23:32");
		ssp.setStatusIcon(R.drawable.icon_complete);

		lll.addView(ssp, ll1Params);
