		CheckBox chexkBox=((CheckBox)view);
		boolean isCheck=chexkBox.isChecked();
		switch(view.getId()){
		case R.id.checkBox1:
			if(isCheck){
				//可以放到一个容器中，存储复选框选择的item
				Toast.makeText(MainActivity.this, "checkBox1"+chexkBox.getText(), 1).show();
			}else{
				//如果不选中，则从复选框中删除item
			}
			break;
