Android 欢迎界面设置

Android 欢迎界面设置

Android  欢迎界面步骤是主界面（就是显示一出来的欢迎界面）构造方法里面开启一个进程，然后将自己finish掉

代码：

WelcomeA.java:

package com.example.welcome;

import android.os.Bundle;
import android.os.Handler;
import android.app.Activity;
import android.content.Intent;

public class WelcomeA extends Activity {

 @Override
 protected void onCreate(Bundle savedInstanceState) {
  super.onCreate(savedInstanceState);
  setContentView(R.layout.main);
  new Handler().postDelayed(new Runnable() {
   @Override
   public void run() {
    Intent intent = new Intent(WelcomeA.this, WhatsnewPagesA.class);
    startActivity(intent);
    WelcomeA.this.finish();
   }
  }, 2000);
 }
}

hello.java:

package com.example.welcome;

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

public class WhatsnewPagesA extends Activity {
 @Override
 protected void onCreate(Bundle savedInstanceState) {
  super.onCreate(savedInstanceState);
  setContentView(R.layout.activity_main);
 }

 @Override
 public boolean onCreateOptionsMenu(Menu menu) {
  // Inflate the menu; this adds items to the action bar if it is present.
  getMenuInflater().inflate(R.menu.main, menu);
  return true;
 }
}
