嗨,我正在使用导航抽屉v4,我问如何在导航抽屉打开时删除该背景阴影。
这是我的NavigationDrawerFragment.java代码
public void setUp(int fragmentId, DrawerLayout drawerLayout) {
mFragmentContainerView = getActivity().findViewById(fragmentId);
mDrawerLayout = drawerLayout;
// set a custom shadow that overlays the main content when the drawer opens
mDrawerLayout.setDrawerShadow(R.drawable.trasparent, GravityCompat.START);
// set up the drawer's list view with items and click listener
ActionBar actionBar = getActionBar();
actionBar.setDisplayHomeAsUpEnabled(true);
actionBar.setHomeButtonEnabled(true);
这是MainActivity.xml
<android.support.v4.widget.DrawerLayout
android:id="@+id/drawer_layout"
android:layout_width="match_parent"
android:layout_height="match_parent">
<!-- Main layout -->
<FrameLayout
android:id="@+id/main_fragment_container"
android:layout_width="match_parent"
android:layout_height="match_parent" />
<ImageView
android:id="@+id/ImageView3_Left"
android:layout_width="match_parent"
android:layout_height="match_parent"
/>
<!-- The navigation drawer -->
<ListView android:id="@+id/left_drawer"
android:layout_width="240dp"
android:layout_height="match_parent"
android:layout_gravity="start"
android:choiceMode="singleChoice"
android:background="#FFFFFFFF"
android:divider="@android:color/transparent"
android:dividerHeight="0dp"/>
</android.support.v4.widget.DrawerLayout>

我找到了解决方案:D
mDrawerLayout.setScrimColor(getResources().getColor(android.R.color.transparent));
在MainActivity.java中添加它

您可以使用setDrawerShadow方法指向透明的drawable:
navigationDrawer.setDrawerShadow(R.drawable.someDrawable, GravityCompat.START);
答案 2 :(得分:0)
这在androidX中对我有效
/*Navigation drawer with transparent background*/
drawerLayout.setScrimColor(getResources().getColor(android.R.color.transparent));
/*Remove navigation drawer shadow/fadding*/
drawerLayout.setDrawerElevation(0);
