ban*_*ing 19 android android-layout android-sdk-tools android-actionbar android-actionbar-compat
我刚刚使用SDK 23更新了我的应用程序到SDK 24.
我的活动出现了一个问题,即显示向上/向主箭头(即getSupportActionBar().setDisplayHomeAsUpEnabled(true)),现在在向上箭头和活动标题之间存在额外的(不需要的)空间.
对于没有向上箭头的活动,活动标题与之前完全相同,这表示额外的填充/边距与向上箭头相关联,而不是与活动标题相关联.
我的问题是如何更改布局,使其与SDK 23看起来与使用SDK 23时相同?
使用SDK 24在向上箭头和标题之间存在较大(不需要的)差距:

这是我的旧build.gradle(SDK 23):
apply plugin: 'com.android.application'
android {
compileSdkVersion 23
buildToolsVersion "23.0.3"
defaultConfig {
applicationId "com.example.myapp"
minSdkVersion 19

这是新的build.gradle(SDK 24):

这在Android问题跟踪器中得到了解答.链接是:

添加app:contentInsetStartWithNavigation="0dp"到工具栏视图.

我认为这个填充是与SDK 24中的Material spec匹配的新标准.首先,您必须通过以下代码隐藏默认工具栏标题:
getSupportActionBar()setDisplayShowTitleEnabled(假).
然后创建一个名为的文件toolbar.xml并在该文件中添加这些代码:
<android.support.v7.widget.Toolbar
xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"
android:id="@+id/toolbar"
android:layout_width="match_parent"
android:layout_height="56dp"
android:background="@color/primary_color"
app:theme="@style/ThemeOverlay.AppCompat"
app:popupTheme="@style/ThemeOverlay.AppCompat.Light"
app:contentInsetStartWithNavigation="0dp">
<TextView
android:id="@+id/toolbar_title"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:layout_marginLeft="16dp" <!-- Add margin -->
android:layout_marginStart="16dp"
android:gravity="left|center"
android:text="Toolbar Title" <!-- Your title text -->
android:textColor="@color/white" <!-- Matches default title styles -->
android:textSize="20sp"
android:fontFamily="sans-serif-medium"/>
</android.support.v7.widget.Toolbar>

如您所见,您可以控制此文件中的所有内容.在toolbar.xml中查看这一行:
应用程式:contentInsetStartWithNavigation = "0dp"
这就是你想要的.祝好运.
