【Android】安卓设置欢迎页

安卓设置全屏启动页面，实现一定时间后跳转：

---

在启动的WelcomeActivity里：

import android.content.Intent;
import android.os.Bundle;
import android.support.v7.app.AppCompatActivity;
import android.view.WindowManager;
import java.util.Timer;
import java.util.TimerTask;

public class WelcomeActivity extends AppCompatActivity {

    public static WelcomeActivity instance = null;
    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        getWindow().addFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN);//隐藏状态栏
        setContentView(R.layout.activity_welcome);
        instance=this;
        final Intent it = new Intent(this, MainActivity.class); //你要转向的Activity
        Timer timer = new Timer();
        TimerTask task = new TimerTask() {
            @Override
            public void run() {
                startActivity(it); //执行
            }
        };
        timer.schedule(task, 1500); //1.5秒后
    }
}

为了结束WelcomeActivity可以在MainActivity里：

---

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        //getWindow().addFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN);//隐藏状态栏
        setContentView(R.layout.activity_main);
        WelcomeActivity.instance.finish();//结束欢迎页activity
        //webView = new FragmentWebView();
        //initView();
        //initData();
        //clickHomeButton();//默认主页面
    }

如果需要显示有几秒到主Activity里或者有点击进入主Activity的功能可以在WelcomeActivity里面自己添加。
