如何使工具栏不与Android中的其他内容重叠? [英] How to make Toolbar not overlap other content in Android?

问题描述

我正在尝试使用工具栏开发活动(该示例或多或少来自教程)，但是工具栏总是与其他内容的一部分重叠. 这是屏幕截图:

I am trying to develop an activity with a toolbar (the example is more or less taken from a tutorial), but the Toolbar always overlaps part of the other content. Here is a screenshot:

蓝色工具栏与其他一些内容重叠.我试图在SO上搜索类似的问题，但只发现一些无关的问题.我还尝试更改某些元素的顺序，并替换了wrap_content<-> match_parent，这最多会使布局更糟.

The blue toolbar overlaps some of the other content. I have tried to search for a similar question on SO but only found something unrelated. I also tried to change the order of some elements and replaced wrap_content <-> match_parent which at most worsens the layout.

我确定我缺少一些非常基本的东西，但是我看不到.

I am sure I am missing something very fundamental, but I do not see what.

activity_main.xml的代码:

    </android.support.design.widget.AppBarLayout>

推荐答案

在您的布局中尝试以下操作:

try this in your layout:

<?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"
    xmlns:tools="http://schemas.android.com/tools"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:fitsSystemWindows="true"
    tools:context=".MainActivity" >

    <android.support.design.widget.AppBarLayout
        android:layout_height="wrap_content"
        android:layout_width="match_parent"
        android:theme="@style/AppTheme.AppBarOverlay">

        <android.support.v7.widget.Toolbar android:id="@+id/toolbar"
            android:layout_width="match_parent"
            android:layout_height="?attr/actionBarSize"
            android:background="?attr/colorPrimary"/>

    </android.support.design.widget.AppBarLayout>

    <GridLayout

        app:layout_behavior="@string/appbar_scrolling_view_behavior"
        android:layout_width="match_parent"
        android:layout_height="match_parent"

        android:useDefaultMargins="true"
        android:alignmentMode="alignBounds"
        android:columnOrderPreserved="false"

            android:layout_gravity="center_horizontal"
            android:id="@+id/textView1"
            />

        <TextView

            />

        <TextView
            android:text="Email address:"

            android:layout_gravity="right"
            />

        <EditText
            android:ems="10"
            />

        <TextView
            android:text="Password:"

            android:layout_column="0"
            android:layout_gravity="right"
            />

        <EditText
            android:ems="8"
            />

        <Space
            android:layout_row="4"
            android:layout_column="0"
            android:layout_columnSpan="3"
            android:layout_gravity="fill"
            />

        <Button
            android:text="Next"
            android:id="@+id/imageButton1"
            android:layout_row="5"
            android:layout_column="3"
            />
    </GridLayout>

</android.support.design.widget.CoordinatorLayout>
