Android启动页的全屏处理方案

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。

使用

/**
 1. 设置状态栏透明
 */
public void setStatusBarTranslucent(Activity activity) {
    if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.LOLLIPOP) {
        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);
    }
}

2. Activity的状态栏透明化

使用

//设置状态栏透明
    public void setStatusBarTranslucent(Activity activity) {
        if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.LOLLIPOP) {
            Window window = activity.getWindow();
            //window.clearFlags(WindowManager.LayoutParams.FLAG_TRANSLUCENT_STATUS);
            window.addFlags(WindowManager.LayoutParams.FLAG_TRANSLUCENT_STATUS);
            window.addFlags(WindowManager.LayoutParams.FLAG_TRANSLUCENT_NAVIGATION);
            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);
            //window.setNavigationBarColor(Color.TRANSPARENT);
        }
    }
 @Override
 protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        //透明化状态栏
        setStatusBarTranslucent(this);
    }
}
