Question

我知道这里曾经有人问过这个问题，我已经研究了解决方案。我想缩小箭头和标题之间的空间，下面的图像有太多空间。

最受欢迎的解决方案是将app:contentInsetStartWithNavigation="0dp"放在我的工具栏XML代码中，例如：

        <android.support.v7.widget.Toolbar
            android:id="@+id/toolbar"
            android:layout_width="match_parent"
            android:layout_height="50dp"
            android:theme="@style/CustomToolbarStyle"
            app:layout_collapseMode="pin"
            app:contentInsetStartWithNavigation="0dp"/>

尽管这样做并运行我的应用程序，但我收到错误消息：

Error:(100) No resource identifier found for attribute 'contentInsetStartWithNavigation' in package 'com.packagename'

搜索该错误导致我尝试尝试解决方案，而不是像添加到我的XML中一样：

            android:contentInsetStart="0dp"
            android:contentInsetLeft="0dp"
            android:contentInsetRight="0dp"
            android:contentInsetEnd="0dp"
            app:contentInsetLeft="0dp"
            app:contentInsetStart="0dp"
            app:contentInsetRight="0dp"
            app:contentInsetEnd="0dp"

但是当我加载我的应用程序时，箭头和标题之间的间距没有改变，仍然有很大的空间。

我在CoordinatorLayout中使用了XML，但看不到为什么会有什么不同。

此外，当我替换时，在我的XML中

<android.support.design.widget.CoordinatorLayout xmlns:android="http://schemas.android.com/apk/res/android"

与

<android.support.design.widget.CoordinatorLayout xmlns:android="http://schemas.android.com/apk/lib/com.mypackage.name"

按照此解决方案：error: No resource identifier found for attribute 'adSize' in package 'com.google.example' main.xml

我仍然会收到错误消息。

这是我的活动的java代码，在onCreate中：

Toolbar toolbar = (Toolbar) findViewById(R.id.toolbar);
setSupportActionBar(toolbar);

//Show the arrow to go back
ActionBar actionbar = getSupportActionBar();
actionbar.setDisplayHomeAsUpEnabled(true);

//show the App title
actionbar.setTitle("Pop");

这是我的活动的xml布局：

Answer 1

您可以将customView添加到工具栏：

Toolbar toolbar = findViewById(R.id.toolbar)
setSupportActionBar(toolbar);
View logo = getLayoutInflater().inflate(R.layout.toolbar_custom_view_layout, null);
toolbar.addView(logo);

xml toolbar_custom_view_layout 可以是这样的：

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout
    xmlns:android="http://schemas.android.com/apk/res/android"
    android:orientation="horizontal"
    android:layout_width="match_parent"
    android:layout_height="match_parent">

    <ImageView
        android:id="@+id/back_arrow_id"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:src="@drawable/back_arrow"
        android:layout_gravity="center_vertical"/>

    <TextView
        android:id="@+id/title_id"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:text="@string/title"
        android:layout_gravity="center_vertical"
        android:marginStart="12dp"/>

</LinearLayout>

使用结果

app:contentInsetEnd="0dp"
app:contentInsetLeft="0dp"
app:contentInsetRight="0dp"
app:contentInsetStart="0dp"
app:contentInsetStartWithNavigation="0dp"

没有使用的输出

app:contentInsetEnd="0dp"
app:contentInsetLeft="0dp"
app:contentInsetRight="0dp"
app:contentInsetStart="0dp"
app:contentInsetStartWithNavigation="0dp"
