论SplashActivity（一）

对于这个相信做过项目的都懂，那就让不太懂的了解了解吧

要设置Splash页面，首先想到的是，如何设置全屏问题，直接上代码，下面有两种方法可以使用

• The first method
  在清单文件（AndroidManifest.xml）中设置

 <activity android:name=".SplashActivity" android:theme="@android:style/Theme.NoTitleBar.Fullscreen" >
        </activity>

• The second method
  在代码（code）中实现

public class SplashActivity extends Activity {

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        // No Titlebar
        this.requestWindowFeature(Window.FEATURE_NO_TITLE);
        setContentView(R.layout.activity_splash);
        // Full Screen
        getWindow().setFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN,
                WindowManager.LayoutParams.FLAG_FULLSCREEN);


    }
}

谨记
（this.requestWindowFeature(Window.FEATURE_NO_TITLE);）
必须在（setContentView(R.layout.activity_splash);）之前

布局文件activity_splash.xml

<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout 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:id="@+id/rl_root" tools:context="com.example.admin.zhbj.SplashActivity">
<ImageView  android:layout_width="match_parent" android:layout_height="match_parent" android:src="@mipmap/splash_horse_newyear"/>
</RelativeLayout>

接下来（Following）我们要处理的是设置SplashActivity的动画效果
单个动画设置

 RelativeLayout rlRoot;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        // No Titlebar
        this.requestWindowFeature(Window.FEATURE_NO_TITLE);
        setContentView(R.layout.activity_splash);
        // Full Screen
        getWindow().setFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN,
                WindowManager.LayoutParams.FLAG_FULLSCREEN);

        rlRoot = (RelativeLayout) findViewById(R.id.rl_root);
        startAnim();
    }
    /** * 开启动画 */
    private void startAnim() {

        //旋转动画
        RotateAnimation rotate = new RotateAnimation(0, 360, Animation.RELATIVE_TO_SELF, 0.5f, Animation.RELATIVE_TO_SELF, 0.5f);
        rotate.setDuration(5000);//动画时间
        rotate.setFillAfter(true);//保持动画状态
        rlRoot.startAnimation(rotate);
    }

对于多个动画（animation）问题code如下：

  /** * 开启动画 */
    private void startAnim() {
        //动画集合
        AnimationSet set = new AnimationSet(false);


        //旋转动画
        RotateAnimation rotate = new RotateAnimation(0, 360, Animation.RELATIVE_TO_SELF, 0.5f, Animation.RELATIVE_TO_SELF, 0.5f);
        rotate.setDuration(5000);//动画时间
        rotate.setFillAfter(true);//保持动画状态
        //缩放动画
        ScaleAnimation scale = new ScaleAnimation(0,1,0,1,Animation.RELATIVE_TO_SELF,0.5f,Animation.RELATIVE_TO_SELF,0.5f);
        scale.setDuration(5000);//动画时间
        scale.setFillAfter(true);//保持动画状态

        //渐变动画
        AlphaAnimation alp = new AlphaAnimation(0,1);
        alp.setDuration(5000);//动画时间
        alp.setFillAfter(true);//保持动画状态

        set.addAnimation(rotate);
        set.addAnimation(scale);
        set.addAnimation(alp);

        rlRoot.startAnimation(set);
    }

动画监听的设置

 //设置动画监听
        set.setAnimationListener(new Animation.AnimationListener() {
            @Override
            public void onAnimationStart(Animation animation) {

            }
            //动画结束
            @Override
            public void onAnimationEnd(Animation animation) {
                startActivity(new Intent(SplashActivity.this, GuideActivity.class));
                finish();
            }


            @Override
            public void onAnimationRepeat(Animation animation) {

            }
        });
