无法在 android 中设置工具栏
Cannot set the toolbar in android
我正在尝试添加自定义工具栏
这是我的toolbar.xml
<?xml version="1.0" encoding="utf-8"?>
<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"
app:theme="@style/ThemeOverlay.AppCompat.Dark.ActionBar"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:minHeight="?attr/actionBarSize"
app:subtitleTextColor="@color/sub_text_color"
app:navigationContentDescription="@string/abc_action_bar_up_description"
android:background="@color/sub_text_color"
app:navigationIcon="?attr/homeAsUpIndicator"
/>
这是我的风格
<!-- Base application theme. -->
<style name="AppTheme" parent="Theme.AppCompat.Light.NoActionBar">
<!-- Customize your theme here. -->
<item name="colorPrimary">@color/colorPrimary</item>
<item name="colorPrimaryDark">@color/colorPrimaryDark</item>

我已将其包含在我的 activity 主
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"

android:layout_width="match_parent"
android:layout_height="match_parent"
tools:context="com.example.myproj.activities.RegisterActivity">
<include layout="@layout/toolbar"/>
在我的主要 activity class 我打电话给
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_register);
toolbar = findViewById(R.id.toolbar);
setSupportActionBar(toolbar);
toolbar.setTitle(R.string.create_account);
}
但我仍然无法在 class 中看到工具栏。
谁能帮我找出错误

请稍微更新一下您的代码:

将 LinearLayout
用作 parent ,child 布局可能隐藏了 toolBar
<LinearLayout 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"
tools:context="com.example.myproj.activities.RegisterActivity">
<include layout="@layout/toolbar"/>
//other childs
</LinearLayout>
要将标题设置为工具栏,请使用 getSupportActionBar().setTitle(title);
toolbar = findViewById(R.id.toolbar);
setSupportActionBar(toolbar);
getSupportActionBar().setTitle(title);
尝试删除自定义工具栏中的主题:
<?xml version="1.0" encoding="utf-8"?>
<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"
app:theme="@style/ThemeOverlay.AppCompat.Dark.ActionBar" //REMOVE THIS
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:minHeight="?attr/actionBarSize"
app:subtitleTextColor="@color/sub_text_color"
app:navigationContentDescription="@string/abc_action_bar_up_description"
android:background="@color/sub_text_color"
app:navigationIcon="?attr/homeAsUpIndicator"
/>
我觉得这个主题很有影响....
造成这种情况的原因有很多。
首先,放置在自定义工具栏之后的视图可能会覆盖在其上,从而挡住了它的视线。请记住,您正在使用 RelativeLayout 作为根元素。因此,您需要确保工具栏之后的视图具有 android:layout_below="@+id/toolbar"
属性。
其次,我建议您使用协调器布局作为根视图,并将自定义工具栏包装在 AppBarLayout 视图中。这样您的布局文件类似于:
<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"
tools:context="ng.shoppi.lafarge_app.MainActivity">
<android.support.design.widget.AppBarLayout
android:layout_width="match_parent"
android:layout_height="wrap_content"
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"
app:popupTheme="@style/AppTheme.PopupOverlay" />
</android.support.design.widget.AppBarLayout>
<include
android:id="@+id/content_main"
layout="@layout/content_main" />
这将使工具栏保持在顶部,并确保其他视图位于工具栏下方。
祝你好运。
