我有一个很奇怪的问题；我希望有人知道这是什么。我在可滚动视图中构建了一个表格，带有 2px 厚的单元格边框。在平板电脑（三星 Galaxy 10.1）上它是完美的，而在 Galaxy Tab 2 上它“停止”仅在滚动视图的可见部分绘制边框。我附上两张图片以显示差异
这是java部分的代码：
@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
super.onCreateView(inflater, container, savedInstanceState);
scrollView1=(HorizontalScrollView) firstView.findViewById(R.id.horizontalScrollView1);
//position the scroller to the present time
scrollView1.post(new Runnable() {
public void run() {
if((Calendar.getInstance().get(Calendar.HOUR_OF_DAY)>3))
scrollView1.scrollTo(CELL_WIDTH*((Calendar.getInstance().get(Calendar.HOUR_OF_DAY))-3), 0);
}
});
headerPaint = new Paint();
headerPaint.setStyle(Paint.Style.STROKE);
headerPaint.setColor(Color.GRAY);
headerPaint.setStrokeWidth(2);
cellPaint = new Paint();
cellPaint.setStyle(Paint.Style.STROKE);
cellPaint.setColor(Color.GRAY);
cellPaint.setStrokeWidth(2);
textViewData.setText(formatter.format(dateToShow.getTime()));
imageButtonDateAfter.setOnClickListener(new View.OnClickListener() {
public void onClick(View v) {
Calendar oggi = Calendar.getInstance();
oggi.set(Calendar.HOUR_OF_DAY, 23);
oggi.set(Calendar.MINUTE, 59);
dateToShow.add(Calendar.DAY_OF_MONTH, 1);
}
});
loadElementiInTable();
return firstView;
}
//for space reasons i show you only the first row code (the hours of the day)
