Android App启动图启动界面（Splash）的简单实现代码

import android.content.Intent;
import android.support.v7.app.AppCompatActivity;
import android.os.Bundle;
import android.view.WindowManager;
public class Splash extends AppCompatActivity {
@Override
protected void onCreate(Bundle savedInstanceState) {
 super.onCreate( savedInstanceState);
 getWindow().addFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN);//隐藏状态栏
 getSupportActionBar().hide();//隐藏标题栏
 setContentView(R.layout.activity_splash);
 Thread myThread=new Thread(){//创建子线程
  @Override
  public void run() {
   try{
    sleep(5000);//使程序休眠五秒
    Intent it=new Intent(getApplicationContext(),MainActivity.class);//启动MainActivity
    startActivity(it);
    finish();//关闭当前活动
   }catch (Exception e){
    e.printStackTrace();
   }
  }
 };
 myThread.start();//启动线程
}
}

getWindow().addFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN); 
getSupportActionBar().hide();
