把一個控制項長期的添加到視窗上

private void showAddress(String address){            wm = (WindowManager) this.getSystemService(Context.WINDOW_SERVICE);            WindowManager.LayoutParams params = new WindowManager.LayoutParams();            params.height = WindowManager.LayoutParams.WRAP_CONTENT;            params.width = WindowManager.LayoutParams.WRAP_CONTENT;            params.flags = WindowManager.LayoutParams.FLAG_NOT_FOCUSABLE                    | WindowManager.LayoutParams.FLAG_NOT_TOUCHABLE                    | WindowManager.LayoutParams.FLAG_KEEP_SCREEN_ON;            params.format = PixelFormat.TRANSLUCENT;            params.type = WindowManager.LayoutParams.TYPE_TOAST;            params.setTitle("Toast");            tv = new TextView(this);            tv.setText(address);            tv.setTextSize(30f);            tv.setTextColor(Color.BLUE);            wm.addView(tv, params);        }

想移除的話用wm.removeView(tv);
