沉浸式

google在Android4.4以后提供了设置沉浸式状态栏的方法

<item name="android:windowTranslucentStatus">true</item>
设置状态栏为透明
android:fitsSystemWindows=”true”

在Android5.0以后，增加了新的API android:statusBarColor 用于设置状态栏的颜色，同时以前的windowTranslucentStatus也是对它有效的，所以如果想通过新的API设置状态栏颜色的话，首先应该将windowTranslucentStatus设置为false，不然是没有效果的。

代码设置:

protected void setImmerseLayout(View view) {// view为标题栏
        if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.KITKAT) {
            Window window = getWindow();
            window.addFlags(WindowManager.LayoutParams.FLAG_TRANSLUCENT_STATUS);
            int statusBarHeight = getStatusBarHeight(this.getBaseContext());
            view.setPadding(0, statusBarHeight, 0, 0);
        }
    }
public int getStatusBarHeight(Context context) {
        int result = 0;
        int resourceId = context.getResources().getIdentifier("status_bar_height", "dimen",
                "android");
        if (resourceId > 0) {
            result = context.getResources().getDimensionPixelSize(resourceId);
        }
        return result;
}

设置全屏，设置状态栏透明

public static void fullScreen(Activity activity) {
        if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.KITKAT) {
            if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.LOLLIPOP) {
                //5.x开始需要把颜色设置透明，否则导航栏会呈现系统默认的浅灰色
                Window window = activity.getWindow();
                View decorView = window.getDecorView();
                //两个 flag 要结合使用，表示让应用的主体内容占用系统状态栏的空间
                int option = View.SYSTEM_UI_FLAG_LAYOUT_FULLSCREEN
                        | View.SYSTEM_UI_FLAG_LAYOUT_STABLE;
                decorView.setSystemUiVisibility(option);
                window.addFlags(WindowManager.LayoutParams.FLAG_DRAWS_SYSTEM_BAR_BACKGROUNDS);
                window.setStatusBarColor(Color.TRANSPARENT));
            } else {
                Window window = activity.getWindow();
                WindowManager.LayoutParams attributes = window.getAttributes();
                int flagTranslucentStatus = WindowManager.LayoutParams.FLAG_TRANSLUCENT_STATUS;
                int flagTranslucentNavigation = WindowManager.LayoutParams.FLAG_TRANSLUCENT_NAVIGATION;
                attributes.flags |= flagTranslucentStatus;
                window.setAttributes(attributes);
            }
        }
    }

给头布局设置布局的paddingtop

public void setBarPadding(View view) {
        if (Build.VERSION.SDK_INT < Build.VERSION_CODES.KITKAT) {
            view.setPadding(view.getPaddingLeft(),UIUtils.dip2px(8),view.getPaddingRight(), view.getPaddingBottom());
        } else {
            view.setPadding(view.getPaddingLeft(), getStatuBarHeight(), view.getPaddingRight(), view.getPaddingBottom());
        }
    }
