问题描述

我对ICS的平板电脑一个code。我要动态地添加ImageView的一个片段。该片段已包含preferencelist。在code添加视图动态如下。我编码此拖放功能。的code这部分细节已经从Android的音乐应用程序TouchInterceptor.java文件。

I have a code on ICS for tablets. I want to add a Imageview dynamicly to a fragment. The fragment already contains preferencelist. The code for adding the view dynamically is as follows. I am coding this drag and drop functionality. This part of the code is taken from TouchInterceptor.java file from android music app.

mWindowParams = new WindowManager.LayoutParams();
mWindowParams.gravity = Gravity.TOP ;
mWindowParams.x = 0;
mWindowParams.y = y
mWindowParams.height = WindowManager.LayoutParams.WRAP_CONTENT;
mWindowParams.width = WindowManager.LayoutParams.WRAP_CONTENT;
mWindowParams.flags = WindowManager.LayoutParams.FLAG_NOT_FOCUSABLE
    | WindowManager.LayoutParams.FLAG_NOT_TOUCHABLE
    | WindowManager.LayoutParams.FLAG_KEEP_SCREEN_ON
    | WindowManager.LayoutParams.FLAG_LAYOUT_IN_SCREEN;
mWindowParams.format = PixelFormat.TRANSLUCENT;
mWindowParams.windowAnimations = 0;

ImageView v = new ImageView(mContext);
int backGroundColor = mContext.getResources().getColor(R.color.bg_background);
v.setBackgroundColor(backGroundColor);
v.setImageBitmap(bm);

mWindowManager = (WindowManager)mContext.getSystemService("window");
mWindowManager.addView(v, mWindowParams);

我指定x windowlayout参数的显示视图时，坐标为0 Eventthen，从片段（右窗格中）的leftside显示的itstead，认为是从右边的窗格中的中间显示，并跨越在右边的窗格中。我做错了什么？请告诉我有工作要做，以纠正呢？

I am specifying the x coordinate of windowlayout param as 0. Eventthen when the view is displayed , itstead of displaying from the leftside of the fragment(the right pane) ,the view is displayed from middle of the right pane and is spanning to the right pane . What I am doing wrong ? Whats has to be done to correct this ?
