FitsSystemWindows不工作

Question

我想爲我的工具欄或/和更改通知欄顏色設置FitsSystemWindows = true。但它不起作用。 我想要做什麼：image

我的代碼在這裏： 樣式

<!-- Base application theme. --> 
<style name="AppTheme" parent="Theme.AppCompat.Light.DarkActionBar"> 
    <!-- Customize your theme here. --> 
    <item name="colorPrimary">@color/colorPrimary</item> 
    <item name="colorPrimaryDark">@color/colorPrimaryDark</item> 
    <item name="colorAccent">@color/colorAccent</item> 
    <item name="android:textColorPrimary">@color/colorWhite</item> 
    <item name="windowActionBar">false</item> 
    <item name="windowNoTitle">true</item> 
    <item name="drawerArrowStyle">@style/DrawerArrowStyle</item> 
</style> 

ActivityDrawerLayout - 其他活動

<android.support.v4.widget.DrawerLayout ... 
    android:fitsSystemWindows="true" 
    tools:context="com.peter.freshNews.activity.DrawerActivity"> 

    <android.support.design.widget.NavigationView ... 
     android:background="@color/drawer_background" 
     android:fitsSystemWindows="true" 
     app:menu="@menu/drawer_menu" /> 
</android.support.v4.widget.DrawerLayout>

     collapsingToolbarLayout.setContentScrimColor(utils.getPageColor(0)); 

     appBarLayout = (AppBarLayout) findViewById(R.id.appBarLayout); 
     viewPager = (ViewPager) findViewById(R.id.viewPager); 

     //----------------------------------t_o_o_l_b_a_r------------------- 
     Toolbar toolbar = (Toolbar) findViewById(R.id.toolbar); 
     if (toolbar != null) { 
      toolbar.setBackgroundResource(R.color.transparent); 
      setSupportActionBar(toolbar); 
     }

     final ActionBar actionBar = getSupportActionBar(); 
     if (actionBar != null) { 
      actionBar.setHomeButtonEnabled(true); 
      actionBar.setDisplayHomeAsUpEnabled(true); 
      actionBar.setBackgroundDrawable(new ColorDrawable(Color.RED)); 
     }

android:fitsSystemWindows是用於使狀態欄和/或導航條是透明的。我不知道它可以應用於工具欄。

至於改變導航欄的顏色部分，你可以做這樣的：

if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.LOLLIPOP) { 
    // clear FLAG_TRANSLUCENT_STATUS flag: 
    window.clearFlags(WindowManager.LayoutParams.FLAG_TRANSLUCENT_STATUS); 
    // add FLAG_DRAWS_SYSTEM_BAR_BACKGROUNDS flag to the window 
    window.addFlags(WindowManager.LayoutParams.FLAG_DRAWS_SYSTEM_BAR_BACKGROUNDS); 
    // finally change the color 
    window.setStatusBarColor(rgbColor); 
} 

而對於工具欄，你可以通過app:contentScrim="?attr/colorPrimary"屬性設置爲CollapsingToolbarLayout做它在XML或代碼：

collapsingToolbarLayout.setContentScrimColor(toolbarColor); 
collapsingToolbarLayout.setExpandedTitleColor(textColor); 
collapsingToolbarLayout.setCollapsedTitleTextColor(textColor);
