[英]Android system buttons are overlapping ListView
I have main activity with tabbed fragments .. in fragment I have listview, but when I scroll to last item on bottom, this item is covered by system buttons: 我有带选项卡式片段的主要活动..在片段中,我具有列表视图,但是当我滚动到底部的最后一个项目时,该项目已被系统按钮覆盖:
here is my activity xml: 这是我的活动xml:
<?xml version="1.0" encoding="utf-8"?>
<android.support.design.widget.CoordinatorLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"

android:id="@+id/main_content"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:fitsSystemWindows="true"
tools:context="com.example.martin.fitnessapp.MainActivity">
<android.support.design.widget.AppBarLayout
android:id="@+id/appbar"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:paddingTop="@dimen/appbar_padding_top"
android:theme="@style/AppTheme.AppBarOverlay">
<android.support.v7.widget.Toolbar

android:layout_width="match_parent"
android:layout_height="?attr/actionBarSize"
android:background="?attr/colorPrimary"
app:layout_scrollFlags="scroll|enterAlways"
app:popupTheme="@style/AppTheme.PopupOverlay">
</android.support.v7.widget.Toolbar>
<android.support.design.widget.TabLayout
android:id="@+id/tabs"
android:layout_width="match_parent"
android:layout_height="wrap_content" />
</android.support.design.widget.AppBarLayout>
<android.support.v4.view.ViewPager
android:id="@+id/container"
android:layout_width="match_parent"
android:layout_height="match_parent"
app:layout_behavior="@string/appbar_scrolling_view_behavior" />
<android.support.design.widget.FloatingActionButton
android:id="@+id/fab"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_gravity="end|bottom"
android:layout_margin="@dimen/fab_margin"
android:src="@android:drawable/ic_dialog_email" />
</android.support.design.widget.CoordinatorLayout>
and here is my current tab xml: 这是我当前的标签XML:
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:paddingBottom="@dimen/activity_vertical_margin"
android:paddingLeft="@dimen/activity_horizontal_margin"
android:paddingRight="@dimen/activity_horizontal_margin"
android:paddingTop="@dimen/activity_vertical_margin">
<!--tools:context="com.example.martin.fitnessapp.MainActivity$PlaceholderFragment">-->
<ListView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:id="@+id/listViewMuscleGroups"
android:layout_alignParentStart="true" />
</RelativeLayout>
For each fragment i have created separated class which extend Fragment class. 我为每个片段创建了单独的类,这些类扩展了Fragment类。 If you need I can add this class too, but I think doesn't matter about that.
如果您需要,我也可以添加此类,但是我认为这无关紧要。
android:layout_alignParentStart="true"
is left (or right depending if you're in RTL languages), you probably also want alignParentTop
in that ListView.The listview probably wants a match_parent
width as well. 左边是
android:layout_alignParentStart="true"
(或者,如果您使用的是RTL语言,则为右边),您可能还希望该ListView中的alignParentTop
。列表视图也可能需要match_parent
宽度。
Anyway, I'm not sure what's going on, but I'd play with moving app:layout_behavior="@string/appbar_scrolling_view_behavior"
to the RelativeLayout that contains the ListView, because that's what causing the ViewPager's fragment content to be drawn like so. 无论如何,我不确定发生了什么,但是我
app:layout_behavior="@string/appbar_scrolling_view_behavior"
到包含ListView的RelativeLayout上,因为这就是导致ViewPager的片段内容以这种方式绘制的原因。
For the record, I don't have much coordinator layout experience. 作为记录,我没有太多的协调员布局经验。
