最简单的耗时组件(窗口activity里面放一个progressBar)

①、先定义一个activity

package com.example.administrator.actionbardemo;

import android.app.Activity;
import android.os.Bundle;
import android.view.Window;

public class LoginSusccess extends Activity {

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        this.requestWindowFeature(Window.FEATURE_NO_TITLE);//去掉标题栏
        setContentView(R.layout.activity_login_susccess);

        LoginSusccess.this.setFinishOnTouchOutside(false); //窗口  activity  点击空白 不取消






    }
}

②、布局文件里面包含一个progressBar和一个Textview

<LinearLayout
    xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:tools="http://schemas.android.com/tools"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:orientation="horizontal"
    android:paddingLeft="@dimen/activity_horizontal_margin"
    android:paddingRight="@dimen/activity_horizontal_margin"
    android:paddingTop="@dimen/activity_vertical_margin"
    android:paddingBottom="@dimen/activity_vertical_margin"
    tools:context="com.example.administrator.actionbardemo.LoginSuscceWss">

    <ProgressBar
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        style="@android:style/Widget.ProgressBar.Small"/>
    <TextView
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:text="请等待..."/>

</LinearLayout>

③、建立一个activity调用一下，别忘了配置activity
