Android启动页的全屏处理方案_android 启动页全屏

Android启动页的全屏处理

1. Activity全屏处理
   在登录页的主题中设置为全屏，并且设置Window的背景为启动图片
   缺点：全屏Activity切换到主页时为非全屏，状态栏会突然出现，造成界面的抖动。

<!--欢迎页面theme-->
<style name="app_welcome_theme" parent="Theme.AppCompat.NoActionBar">
    <item name="android:windowBackground">@drawable/app_welcome_bg</item>
    <item name="android:windowFullscreen">true</item>
</style>

public void setStatusBarTranslucent(Activity activity) {

        Window window = activity.getWindow();
        window.setNavigationBarColor(Color.BLACK);
        window.clearFlags(WindowManager.LayoutParams.FLAG_TRANSLUCENT_STATUS);
        window.addFlags(WindowManager.LayoutParams.FLAG_DRAWS_SYSTEM_BAR_BACKGROUNDS);
        View decorView = window.getDecorView();
        int option = View.SYSTEM_UI_FLAG_LAYOUT_FULLSCREEN
                | View.SYSTEM_UI_FLAG_LAYOUT_STABLE;
        decorView.setSystemUiVisibility(option);
        //透明着色
        window.setStatusBarColor(Color.TRANSPARENT);
    }
}

 @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        //透明化状态栏
        setStatusBarTranslucent(this);
