Android 选项卡式活动底部关闭屏幕

本文介绍了Android 选项卡式活动底部关闭屏幕的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！ 问题描述

有人知道为什么在android中新生成的选项卡式活动中底部不在屏幕上吗?

ViewPager 对于整个屏幕来说太长了

如果将子 Fragments 中的所有视图对齐到屏幕底部，则它们会在 55dp 处离开屏幕.

谢谢，

保罗

P.S.:生成代码的完整 XML:

<?xml version="1.0" encoding="utf-8"?><android.support.design.widget.CoordinatorLayout xmlns:android="schemas.android/apk/res/android"xmlns:app="schemas.android/apk/res-auto"xmlns:tools="schemas.android/tools"android:id="@+id/main_content"android:layout_width="match_parent"android:layout_height="match_parent"安卓:fitsSystemWindows="真"工具:context="comfylight.bulbtest.FooBar">

anybody an idea why the bottom is off screen in a new generated tabbed activity in android?

ViewPager is too long for the total screen

<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" />

Result all views in the child Fragments are off screen by the 55dp if you align them to the bottom of the screen.

Thanks,

解决方案

Maybe this design will help in what you need, add:

<LinearLayout android:id="@+id/test" android:layout_width="match_parent" android:layout_height="match_parent" android:orientation="vertical"> </LinearLayout>

in your xml:

<?xml version="1.0" encoding="utf-8"?> <android.support.design.widget.CoordinatorLayout xmlns:android="schemas.android/apk/res/android" xmlns:app="schemas.android/apk/res-auto" xmlns:tools="schemas.android/tools" android:id="@+id/main_content" android:layout_width="match_parent" android:layout_height="match_parent" android:fitsSystemWindows="true" tools:context="comfylight.bulbtest.FooBar"> <LinearLayout android:id="@+id/test" android:layout_width="match_parent" android:layout_height="match_parent" android:orientation="vertical"> <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.NoActionBar.AppBarOverlay"> <android.support.v7.widget.Toolbar android:id="@+id/toolbar" android:layout_width="match_parent" android:layout_height="?attr/actionBarSize" android:background="?attr/colorPrimary" app:layout_scrollFlags="scroll|enterAlways" app:popupTheme="@style/AppTheme.NoActionBar.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" /> </LinearLayout> </android.support.design.widget.CoordinatorLayout>
