简单模拟实现简单的当登录延时的效果

①、先建立一个activaty去部署我们的登陆界面

package com.example.administrator.actionbardemo;

import android.app.Activity;
import android.content.Intent;
import android.os.Bundle;
import android.view.View;
import android.widget.Button;
import android.widget.EditText;
import android.widget.TextView;
import android.widget.Toast;

public class MainActivity extends Activity {

    private Button denglu;  //登录按钮
    private TextView new_user;  //新用户连接

    private String user = "111111";  //用户名
    private String possword = "111111";   //用户密码
    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);

        denglu = (Button) findViewById(R.id.denglu);  //绑定 按钮
        //登录按钮的监听事件
        denglu.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {
                EditText user_name = (EditText) findViewById(R.id.user_name);  //绑定  用户名  编辑框
                EditText pwd = (EditText) findViewById(R.id.pwd);   //绑定 密码  输入框
                if(pwd.getText().toString().equals(possword) && user_name.getText().toString().equals(user)){
                    Intent intent = new Intent(MainActivity.this,CopyProgressBarDemo.class);  //绑定Activaty
                    startActivity(intent);  //启动Activity
                    Toast.makeText(getApplicationContext(),"登陆成功",Toast.LENGTH_SHORT).show();
//                    finish();   //结束本Activity
                }else{
                    Toast.makeText(getApplicationContext(),"用户名或密码不正确",Toast.LENGTH_SHORT).show();
                }

            }
        });
        new_user = (TextView) findViewById(R.id.new_user);  //绑定  新用户  TextView
        //绑定监听事件
        new_user.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {
                Intent intent = new Intent(MainActivity.this,Zhuce.class);
                startActivity(intent);
            }
        });

    }
}

这里是MainActivity的布局xml文件

<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="vertical"
    android:paddingLeft="@dimen/activity_horizontal_margin"
    android:paddingRight="@dimen/activity_horizontal_margin"
    android:paddingTop="@dimen/activity_vertical_margin"
    android:paddingBottom="@dimen/activity_vertical_margin"
    android:background="@drawable/login_backgrond"
    tools:context=".MainActivity">

    <EditText
        android:id="@+id/user_name"
        android:layout_width="220dp"
        android:layout_height="40dp"
        android:layout_gravity="center_horizontal"
        android:layout_marginTop="80dp"
        android:singleLine="true"
        android:drawableLeft="@drawable/denglu_per"
        android:background="@drawable/edit_text_shape"
        android:hint="请输入用户帐号"
        />
    <EditText
        android:id="@+id/pwd"
        android:layout_width="220dp"
        android:layout_height="40dp"
        android:layout_gravity="center_horizontal"
        android:layout_marginTop="15dp"
        android:password="true"
        android:singleLine="true"
        android:drawableLeft="@drawable/denglu_lock"
        android:background="@drawable/edit_text_shape"
        android:hint="请输入用户密码"/>
    <LinearLayout
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:orientation="horizontal"
        android:layout_gravity="center_horizontal">
        <CheckBox
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:text="记住密码"
            android:checked="true"/>
        <CheckBox
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:text="自动登录"
            android:checked="false"/>
        </LinearLayout>
    <Button
        android:id="@+id/denglu"
        android:layout_width="200dp"
        android:layout_height="wrap_content"
        android:layout_gravity="center_horizontal"
        android:layout_marginTop="20dp"
        android:text="登录"
        android:textSize="24dp"
        android:background="@drawable/button_type"/>
    <LinearLayout
        android:layout_width="wrap_content"
        android:layout_height="match_parent"
        android:layout_gravity="right|end"
        android:orientation="horizontal">
        <TextView
            android:id="@+id/forget_pwd"
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:layout_gravity="bottom"
            android:text="忘记密码"
            android:textColor="#00F9FF"/>
        <TextView
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:text=" | "
            android:layout_gravity="bottom"/>
        <TextView
            android:id="@+id/new_user"
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:text="新用户"
            android:layout_gravity="bottom"
            android:textColor="#00F9FF"/>
    </LinearLayout>
</LinearLayout>

②、新建一个Activity，在这个Activity中，我加入了一个耗时操作去模拟。

package com.example.administrator.actionbardemo;

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

import java.util.Timer;
import java.util.TimerTask;

public class CopyProgressBarDemo 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);

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

        final Handler myHandler = new Handler(){
            @Override
            public void handleMessage(Message msg) {
                super.handleMessage(msg);
                if (msg.what == 0x111){
                    finish();
                }
            }
        };

        //定义一个计时器，让该计时器周期性的执行指定任务
        final int[] count = {0};
        new Timer().schedule(new TimerTask() {
            @Override
            public void run() {
                count[0]++;
                if(count[0] == 10){
                    myHandler.sendEmptyMessage(0x111);
                }
            }
        },0,500);

    }
}

布局文件,该文件只包含了一个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>
