備份之用:
public void showSystemDialog(String showInfo, final int flag){AlertDialog.Builder b = new AlertDialog.Builder(context);b.setMessage(showInfo);b.setPositiveButton("確定", new DialogInterface.OnClickListener(){public void onClick(DialogInterface dialog, int id){switch (flag){case 0:Intent intent = new Intent(Settings.ACTION_WIRELESS_SETTINGS);intent.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK);context.startActivity(intent);break;case 1:case 3: // 如果是GPRS,則提醒if (moblieFlag == false){moblieFlag = true;}default:break;}d.dismiss();}}).setNegativeButton("取消", new DialogInterface.OnClickListener(){public void onClick(DialogInterface dialog, int id){d.dismiss();}});d = b.create();d.getWindow().setType(WindowManager.LayoutParams.TYPE_SYSTEM_ALERT);d.show();WindowManager.LayoutParams lp = d.getWindow().getAttributes();WindowManager wm = (WindowManager) context.getSystemService(Context.WINDOW_SERVICE);Display display = wm.getDefaultDisplay();if (display.getHeight() > display.getWidth()){lp.width = (int) (display.getWidth() * 1.0);}else{lp.width = (int) (display.getWidth() * 0.5);}d.getWindow().setAttributes(lp);}
