方案一

1. 将状态栏透明

• 代码设置

        if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.LOLLIPOP) {
            //5.0及以上
            View decorView = getWindow().getDecorView();
            int option = View.SYSTEM_UI_FLAG_LAYOUT_FULLSCREEN
                    | View.SYSTEM_UI_FLAG_LAYOUT_STABLE;
            decorView.setSystemUiVisibility(option);
            getWindow().setStatusBarColor(Color.TRANSPARENT);
        } else if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.KITKAT) {
            //4.4到5.0
            WindowManager.LayoutParams localLayoutParams = getWindow().getAttributes();
            localLayoutParams.flags = (WindowManager.LayoutParams.FLAG_TRANSLUCENT_STATUS | localLayoutParams.flags);
        }

• xml配置

//values
<style name="TranslucentTheme" parent="AppTheme">
</style>

//values-v19
<style name="TranslucentTheme" parent="Theme.AppCompat.Light.NoActionBar">
        <item name="android:windowTranslucentStatus">true</item>
        <item name="android:windowTranslucentNavigation">false</item>
</style>

//values-v21
<style name="TranslucentTheme" parent="Theme.AppCompat.Light.NoActionBar">
        <item name="android:windowTranslucentStatus">true</item>
        <item name="android:windowTranslucentNavigation">false</item>
        <item name="android:statusBarColor">@android:color/transparent</item>
</style>

1. 着色
   android:fitsSystemWindows="true"不让布局延伸到状态栏，为根布局设置paddingTop值。

//values
<dimen name="padding_top">0dp</dimen>
//values-v19
<dimen name="padding_top">25dp</dimen>

NavigationView未延伸到状态栏解决方法：

    private void navViewToTop() {
        if (Build.VERSION.SDK_INT < Build.VERSION_CODES.LOLLIPOP) {
            mDrawerLayout.setFitsSystemWindows(true);
            mDrawerLayout.setClipToPadding(false);
        }
    }

方案二

1. 将状态栏透明
2. 着色

• 在布局文件中添加android:fitsSystemWindows="true"属性;
• 创建View并添加到状态栏

    private void addStatusBarView() {
        View view = new View(this);
        view.setBackgroundColor(getResources().getColor(R.color.colorPrimary));
        LinearLayout.LayoutParams params = new LinearLayout.LayoutParams(ViewGroup.LayoutParams.MATCH_PARENT,
                getStatusBarHeight(this));
        ViewGroup decorView = (ViewGroup) findViewById(android.R.id.content);
        decorView.addView(view, params);
    }
