自定义preferences界面和对话框（带图标的preferences）

虽然市面上有很多天气预报，但是功能不喜欢

但是很想做个天气预报预警，想用Preferences做了个界面

界面如下

   效果图：

其中最主要的是重写 onCreateView方法

	@Override
	protected View onCreateView(ViewGroup parent) {
		// TODO Auto-generated method stub
		//如果不加这句，下拉的时候界面会被重新刷新，界面上的数据就会丢失
		if(view!=null)return view;

		view = LayoutInflater.from(getContext()).inflate(
				R.layout.perference_timerpicker, parent, false);
		icon = (ImageView) view.findViewById(R.id.image_icon);
		summary = (TextView) view.findViewById(android.R.id.summary);
		//android自定义的ID不能再开始时变化所以使用setSummary方法改变
	    this.setSummary(PreferenceSaveUtils.getString(this, getKey(), "08:00"));
//		summary.setText(PreferenceSaveUtils.getString(this, getKey(), "08:00"));
		return view;
	}
