代码如下：启动页面Activity代码如下：

public class SplashScreen  extends BaseActivity{/*    * Called when the activity is first created.    */    @Override    public void onCreate(Bundle icicle) {        super.onCreate(icicle);        setContentView(R.layout.splashscreen);        getWindow().setFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN, WindowManager.LayoutParams.FLAG_FULLSCREEN); // 设置全屏,不需要可去掉        new Handler().postDelayed(new Runnable() {            public void run() {                /* Create an Intent that will start the Main WordPress Activity. */                Intent mainIntent = new Intent(SplashScreen.this, MainActivity.class);                SplashScreen.this.startActivity(mainIntent);                overridePendingTransition(R.anim.activity_in, R.anim.activity_out);// 淡出淡入动画效果                SplashScreen.this.finish();            }        }, 3000); //2900 for release    }}

AndroidManifest.xml配置如下

 <activity            android:name=".activity.SplashScreen"            android:launchMode="singleTop"            android:screenOrientation="portrait"            android:theme="@style/Theme.AppStartLoad">            <intent-filter>                <action android:name="android.intent.action.MAIN" />                <category android:name="android.intent.category.LAUNCHER" />            </intent-filter>        </activity>

styles.xml配置如下：

    <style name="Theme.AppStartLoad" parent="MainTheme">        <item name="android:windowBackground">@mipmap/aplash_back</item><!--一张图片-->        <item name="android:windowNoTitle">true</item>    </style>

overridePendingTransition(R.anim.activity_in, R.anim.activity_out);// 淡出淡入动画效果
