Android 欢迎界面实现

案例打开QQ 1.5 秒后进入界面 :

首先:

创建avtivity_welcome.xml 布局
添加个 代码如下:

< LinearLayout
xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical"
android:gravity="center">

然后 创建WelcomeActivity 继承 activity 实现 AnimationListener

代码如下:

public class WelcomeActivity extends AppCompatActivity implements Animation.AnimationListener {

//声名 ImageView id
private ImageView welcomeImg;

@Override
protected void onCreate (Bundle savedInstanceState) {
super.onCreate (savedInstanceState);
setContentView (R.layout.activity_weleco_m);

    welcomeImg = (ImageView) findViewById(R.id.welcomeImg);

     //设置动画时间 结束 后跳转到指定页面
    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秒后跳转

}

@Override

public  void  onAnimationStart (Animation animation)  {

}

@Override

public  void  onAnimationEnd (Animation animation)  { 

}

@Override
public  void  onAnimationRepeat (Animation animation)  {

}

}
