我正在尝试在导航抽屉活动中实现ProgressBar,但它像这样覆盖整个屏幕。
我尝试在我的ProgressBar中设置style="?android:attr/progressBarStyleSmall"
但没有成功
我们是cML圆角
<?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:id="@+id/drawer_layout"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:fitsSystemWindows="true"
tools:openDrawer="start">
<include
layout="@layout/app_bar_home_screen"
android:layout_width="match_parent"
android:layout_height="match_parent" />
<android.support.design.widget.NavigationView
android:id="@+id/nav_view"
android:layout_width="wrap_content"
android:layout_height="match_parent"
android:layout_gravity="start"
android:fitsSystemWindows="true"
app:headerLayout="@layout/nav_header_home_screen"
app:menu="@menu/activity_home_screen_drawer" />
<ProgressBar
android:id="@+id/progressBar1"
style="?android:attr/progressBarStyleSmall"
android:layout_width="100dp"
android:layout_height="100dp"
android:layout_centerHorizontal="true" />
</android.support.v4.widget.DrawerLayout>
终于完成了
在创建新的NavigationDrawer Activity时,Android Studio会生成4个XML文件。之前我在activity_home_screen.xml
实施了ProgressBar。现在尝试在content_home_screen.xml
实施后,它起作用了
注意:
HomeScreenActivity
是我的活动名称
我的content_home_screen.xml
文件
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout 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"
app:layout_behavior="@string/appbar_scrolling_view_behavior"
tools:context=".HomeScreenActivity"
tools:showIn="@layout/app_bar_home_screen">
<LinearLayout
android:id="@+id/header_search"
android:layout_width="match_parent"
android:layout_height="80dp"
android:orientation="horizontal"
android:paddingEnd="16dp"
android:weightSum="5">
<!-- Some Code.... -->
</LinearLayout>
<View
android:id="@+id/content_view"
android:layout_width="wrap_content"
android:layout_height="2dp"
android:layout_below="@id/header_search"
android:background="@drawable/gradient_view" />
<ProgressBar
android:id="@+id/progressBar"
style="?android:attr/progressBarStyleSmall"
android:layout_width="100dp"
android:layout_height="100dp"
android:layout_centerInParent="true" />
</RelativeLayout>
这是因为进度条的硬编码大小
android:layout_width =“100dp”android:layout_height =“100dp”
试试这个:
<ProgressBar
android:id="@+id/progressBar1"
style="?android:attr/progressBarStyleSmall"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_centerHorizontal="true" />
将ProgressBar放在NavigationView中:
<android.support.design.widget.NavigationView
android:id="@+id/nav_view"
android:layout_width="wrap_content"
android:layout_height="match_parent"
android:layout_gravity="start"
android:fitsSystemWindows="true"
app:headerLayout="@layout/nav_header_home_screen"
app:menu="@menu/activity_home_screen_drawer">
<ProgressBar
android:id="@+id/progressBar1"
style="?android:attr/progressBarStyleSmall"
android:layout_width="100dp"
android:layout_height="100dp"
android:layout_centerHorizontal="true" />
</android.support.design.widget.NavigationView>
