我试图让我的导航抽屉进入状态栏。我已经广泛阅读了ScrimInsetsFrameLayout视图,并尝试实现它,但出于某种原因,它不会被淘汰。
这是我使用/编写的代码。
XML DrawerLayout:
<android.support.v4.widget.DrawerLayout
android:id="@+id/drawer_layout"
xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent">
<FrameLayout
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical">
<FrameLayout
android:id="@+id/content_frame"
android:layout_width="match_parent"
android:layout_height="match_parent" />
<include layout="@layout/toolbar" />
</FrameLayout>
<com.andrewq.planets.util.ScrimInsetsFrameLayout
xmlns:app="http://schemas.android.com/apk/res-auto"
android:id="@+id/linearLayout"
android:layout_width="304dp"
android:layout_height="match_parent"
android:layout_gravity="start"
android:fitsSystemWindows="true"
app:insetForeground="#4000">
<ListView
android:id="@+id/left_drawer"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:choiceMode="singleChoice" />
</com.andrewq.planets.util.ScrimInsetsFrameLayout>
</android.support.v4.widget.DrawerLayout>

最后,这里是我的styles.xml for values-v21:
<?xml version="1.0" encoding="utf-8"?>
<resources>
<style name="AppThemeNavDrawer" parent="Theme.AppCompat.NoActionBar">
<item name="colorAccent">#F8F8F8</item>
<item name="android:windowTranslucentStatus">true</item>
<item name="windowActionBar">false</item>
<item name="windowActionModeOverlay">true</item>
<item name="android:windowDrawsSystemBarBackgrounds">true</item>
<item name="android:statusBarColor">@android:color/transparent</item>
</style>
</resources>
我查看了2014 I / O应用源代码以及this问题,但我不知道有什么不同。
这是我到目前为止的截图,减去状态栏下的抽屉:
我已经完成了其他所有工作,这是我需要做的最后一件事。非常感谢帮助!
为了澄清一下,我想让图像在状态栏下着色,就像大多数Google Apps和Google Now一样。

将android:fitsSystemWindows="false"
添加到DrawerLayout将解决问题
答案 1 :(得分:24)
有不同的方法可以达到预期的效果。您可以通过样式或代码启用半透明。
我创建了一个MaterialDrawer(遵循Android Material Design Guidelines),它实现了所有这些并为您处理所有事情。在此处阅读更多内容:https://github.com/mikepenz/MaterialDrawer/
如果你想自己创建它,你总是要决定哪个是你想要支持的最低api和/或你是否需要拆分你的风格。
因此,要启用translucentStatusbar,您必须至少使用API v19,或者为v19 + values-v19
创建分隔样式
这将看起来像这样
<style name="YourTheme.TranslucentStatus" parent="Theme.AppCompat.Light.NoActionBar">
<item name="android:windowTranslucentStatus">true</item>
</style>
现在,这将把您的完整布局移到状态栏下方。几乎在所有情况下,您现在都想在抽屉内容和普通视图内容的顶部添加填充。
您可以通过添加24dp
填充来完成此操作。
这不是一个非常好的实现。因此,使用Google IO 2014应用中使用的ScrimInsetsLayout有不同的方法。 https://github.com/google/iosched/blob/master/android/src/main/java/com/google/samples/apps/iosched/ui/widget/ScrimInsetsFrameLayout.java
这将是您的内容布局,您可以在其上设置状态栏的颜色。您可以在此处找到有关如何使用它的详细说明:https://stackoverflow.com/a/26932228
需要一些时间来适应样式和/或ScrimInsetsLayout
。

关于如何以编程方式处理此问题的更复杂的示例:
if (Build.VERSION.SDK_INT >= 19 && Build.VERSION.SDK_INT < 21) {
//enable translucent statusbar via flags
setTranslucentStatusFlag(true);
}
if (Build.VERSION.SDK_INT >= 19) {
mActivity.getWindow().getDecorView().setSystemUiVisibility(View.SYSTEM_UI_FLAG_LAYOUT_STABLE | View.SYSTEM_UI_FLAG_LAYOUT_FULLSCREEN);
}
if (Build.VERSION.SDK_INT >= 21) {
//we don't need the translucent flag this is handled by the theme
setTranslucentStatusFlag(false);
//set the statusbarcolor transparent to remove the black shadow
mActivity.getWindow().setStatusBarColor(Color.TRANSPARENT);
}
//add a padding to the content of the drawer (25dp on devices starting with api v19)
mDrawerContentRoot.setPadding(0, mActivity.getResources().getDimensionPixelSize(R.dimen.tool_bar_top_padding), 0, 0);
// define the statusBarColor
mDrawerContentRoot.setInsetForeground(mStatusBarColor);
private void setTranslucentStatusFlag(boolean on) {
if (Build.VERSION.SDK_INT >= 19) {
Window win = mActivity.getWindow();
WindowManager.LayoutParams winParams = win.getAttributes();
final int bits = WindowManager.LayoutParams.FLAG_TRANSLUCENT_STATUS;
if (on) {
winParams.flags |= bits;
} else {
winParams.flags &= ~bits;
}
win.setAttributes(winParams);
}
}

解决此问题的完整解决方案是清理项目中的所有布局。布局和样式的某种组合导致了麻烦。

答案 2 :(得分:4)
您需要创建一个新的styles.xml并将该文件放在style-v19文件夹中,因为状态栏半透明方法不适用于pre kitkat设备。
<style name="AppTheme" parent="Theme.AppCompat.Light.NoActionBar" >
<item name="android:windowTranslucentStatus">true</item>
</style>
之后,您将看到您的应用程序位于状态栏下但是您需要为工具栏提供填充以进行精确实现。创建一个维度-v19并添加
<dimen name="ToolBarPaddingTop">24dp</dimen>
在ToolBar中使用它
<android.support.v7.widget.Toolbar xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:background="@color/accent_material_light"
android:theme="@style/ThemeOverlay.AppCompat.Dark"
android:fitsSystemWindows="true"
android:paddingTop="@dimen/ToolBarPaddingTop">
</android.support.v7.widget.Toolbar>
答案 3 :(得分:3)
这对我有用:
android:windowTranslucentStatus
设置为true
。这将使你的状态栏几乎从Lollipop透明。Toolbar
参数定义android:colorPrimary
的颜色。android:fitsSystemWindows="true"
。Toolbar
和Drawer
上使用它。答案 4 :(得分:1)
我认为您还需要将android:fitsSystemWindows="true"
添加到android.support.v4.widget.DrawerLayout
代码中。
