让用户等待执行完。?

import android.widget.PopupWindow;


//新建实例
final PopupWindow popupWindow = new PopupWindow();




//显示
popupWindow.setOutsideTouchable(false);
popupWindow.setFocusable(false);//点击区域外不会消失，点击返回会执行back事件
popupWindow.setHeight(ViewGroup.LayoutParams.WRAP_CONTENT);
popupWindow.setWidth(ViewGroup.LayoutParams.WRAP_CONTENT);
View view = LayoutInflater.from(MainActivity.this).inflate(R.layout.popup,null);
popupWindow.setContentView(view);
popupWindow.showAtLocation(getWindow().getDecorView(), Gravity.CENTER,0,0);


//消失
popupWindow.dismiss();

?popup.xml

<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:orientation="vertical" >

    <ProgressBar
        android:id="@+id/progressBar1"
        style="?android:attr/progressBarStyleLarge"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_centerInParent="true"
        android:clickable="false"
