我用导航抽屉编写应用程序代码。我有一个菜单列表与自定义菜单项。每个项目,左边都有指示器,imageview和textview。抽屉布局工作正常,但它为菜单列表的每个项目创建左/右边距。 这是抽屉布局:
<?xml version="1.0" encoding="utf-8"?>
<android.support.v4.widget.DrawerLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:id="@+id/drawer_layout_nav"
tools:context="com.gem.timekeeper.screen.main.leftnavigation.MainActivity">
<include layout="@layout/content_main" />
<android.support.design.widget.NavigationView
android:id="@+id/nav_view"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:layout_gravity="start"
android:background="@color/colorPrimary"
android:fitsSystemWindows="true"
app:headerLayout="@layout/nav_header_main"
app:menu="@menu/menu_navigation_drawer" >
<android.support.constraint.ConstraintLayout
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_gravity="bottom"
android:clickable="true"
>
<android.support.constraint.Guideline
android:layout_width="wrap_content"
android:layout_height="wrap_content"
app:layout_constraintGuide_percent="0.06"
android:orientation="vertical"
android:id="@+id/gl_v_6"/>
<android.support.constraint.Guideline
android:layout_width="wrap_content"
android:layout_height="wrap_content"
app:layout_constraintGuide_percent="0.94"
android:orientation="vertical"
android:id="@+id/gl_v_94"/>
<android.support.constraint.Guideline
android:layout_width="wrap_content"
android:layout_height="wrap_content"
app:layout_constraintGuide_percent="0.8"
android:orientation="horizontal"
android:id="@+id/gl_h_80"/>
<Button
android:layout_width="0dp"
android:layout_height="wrap_content"
android:background="@drawable/border_button_logout_nav"
android:id="@+id/btn_unlock_Nav"
app:layout_constraintStart_toEndOf="@id/gl_v_6"
app:layout_constraintEnd_toStartOf="@id/gl_v_94"
app:layout_constraintBottom_toTopOf="@id/gl_h_80"
android:fontFamily="sans-serif-medium"
android:textStyle="normal"
android:textColor="@color/colorPrimary"
android:letterSpacing="0.03"
android:text="Đăng xuất"/>
</android.support.constraint.ConstraintLayout>
</android.support.design.widget.NavigationView>
</android.support.v4.widget.DrawerLayout>
我自定义菜单项:
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent"
xmlns:tools="http://schemas.android.com/tools"
android:background="@color/colorPrimaryDark"
android:orientation="horizontal">
<ImageView
android:layout_gravity="center"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:src="@drawable/ic_cham_cong"
/>
<TextView
android:layout_gravity="center"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_marginLeft="@dimen/margin_medium"
android:textSize="16sp"
android:fontFamily="sans-serif"
android:textStyle="normal"
android:textColor="#ffffff"
android:letterSpacing="0.03"
android:text="@string/common_mark_work_point"
android:id="@+id/tv_mark_work_point_left_nav"
/>
</LinearLayout>
