final UpdateDialog updateDialog=new UpdateDialog(ac, R.style.dialog_style);
Window mwWindow=updateDialog.getWindow();

mwWindow.setGravity(Gravity.BOTTOM);
mwWindow.setAttributes(lp);
if(serVerCode>verCode){
updateDialog.setMsg(getResources().getString(R.string.update_mes_new));
updateDialog.setBtText(getResources().getString(R.string.update_now));
updateDialog.setOnBtnclick(new BtnClickListener() {


@Override
public void onClick() {

updateDialog.dismiss();
}
});


}else{
String vername=ac.getPackageManager().getPackageInfo(ac.getPackageName(), 0).versionName;
updateDialog.setMsg(getString(R.string.update_msg_now_is_new)+vername);
updateDialog.setBtText(getString(R.string.update_sure));
updateDialog.setOnBtnclick(new BtnClickListener() {


@Override
