然后在你的活动/片段中:
public void onCreate(Bundled savedInstanceState) {
super.onCreate(savedInstanceState);
// Your normal setup. Blah blah ...
// As we're using a Toolbar, we should retrieve it and set it
// to be our ActionBar
Toolbar toolbar = (...) findViewById(R.id.my_awesome_toolbar);
setSupportActionBar(toolbar);
// Now retrieve the DrawerLayout so that we can set the status bar color.
// This only takes effect on Lollipop, or when using translucentStatusBar
// on KitKat.
DrawerLayout drawerLayout = (...) findViewById(R.id.my_drawer_layout);
drawerLayout.setStatusBarBackgroundColor(yourChosenColor);

步骤2
将NavigationView添加到你的DrawerLayout:
<android.support.v4.widget.DrawerLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"
android:id="@+id/drawer_layout"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:fitsSystemWindows="true"> <!-- this is important -->
<!-- Your contents -->
<android.support.design.widget.NavigationView
android:id="@+id/navigation"
android:layout_width="wrap_content"
android:layout_height="match_parent"
android:layout_gravity="start"
app:menu="@menu/navigation_items" /> <!-- The items to display -->
</android.support.v4.widget.DrawerLayout>
<style name="NavigationStyle" parent="Theme.AppCompat.Light.NoActionBar">
<!-- Customize your theme here. -->
<item name="colorPrimary">@color/primaryColor</item>
<item name="colorPrimaryDark">@color/primaryColorDark</item>
<!-- To Make Navigation Drawer Fill Status Bar and become Transparent Too -->
<item name="android:windowDrawsSystemBarBackgrounds">true</item>
<item name="android:statusBarColor">@android:color/transparent</item>
</style>
@Override
public void onDrawerSlide(View drawerView, float slideOffset) {
super.onDrawerSlide(drawerView, slideOffset);
try {
//int currentapiVersion = android.os.Build.VERSION.SDK_INT;
if (android.os.Build.VERSION.SDK_INT >= android.os.Build.VERSION_CODES.LOLLIPOP){
// Do something for lollipop and above versions
Window window = getWindow();
// 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 to any color with transparency
window.setStatusBarColor(getResources().getColor(R.color.colorPrimaryDarktrans));}
} catch (Exception e) {
Crashlytics.logException(e);
}
}
这将改变你的状态栏颜色为透明当你打开抽屉
现在，当你关闭抽屉，你需要改变状态栏颜色再次为深色。你可以这样做。
public void onDrawerClosed(View drawerView) {
super.onDrawerClosed(drawerView);
try {
if (android.os.Build.VERSION.SDK_INT >= android.os.Build.VERSION_CODES.LOLLIPOP){
// Do something for lollipop and above versions
Window window = getWindow();
// 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 again to dark
window.setStatusBarColor(getResources().getColor(R.color.colorPrimaryDark));}
} catch (Exception e) {
Crashlytics.logException(e);
}
}
