android开发物理世界中水平移动怎么设置

代码中设置：

LinearLayout.LayoutParams params = new LinearLayout.LayoutParams(LayoutParams.FILL_PARENT,

LayoutParams.FILL_PARENT)

params.setMargins(0, 5, 2, 0)

LinearLayout.LayoutParams params = new LinearLayout.LayoutParams(LayoutParams.FILL_PARENT,

LayoutParams.FILL_PARENT)

params.setMargins(0, 5, 2, 0)

WindowManager windowManager = getWindowManager()

Display display = windowManager.getDefaultDisplay()

WindowManager.LayoutParams lp = getWindow().getAttributes()

lp.width = WindowManager.LayoutParams.MATCH_PARENT

lp.height = WindowManager.LayoutParams.MATCH_PARENT

getWindow().setAttributes(lp)

HorizontalScrollView hv = new HorizontalScrollView(context)hv.setLayoutParams(new LayoutParams(LayoutParams.FILL_PARENT,LayoutParams.WRAP_CONTENT))hv.setFillViewport(true)hv.addView(listview)mainPanel.addView(hv)这样不管用，郁闷ing。
