无法更改工具栏的颜色(Can't change the color of toolbar)

任何人都可以请,解释我,为什么我的工具栏不会改变它的颜色,即使我创建了另一种风格,如:

<style name="AppTheme.NoActionBar">
    <item name="windowActionBar">false</item>
    <item name="windowNoTitle">false</item>
</style>

将它添加到我的清单文件中,如:

<activity
    android:name=".SettingsActivity"
    android:label="@string/title_activity_settings"
    android:parentActivityName=".MainActivity">
    <meta-data
        android:theme="@style/AppTheme.NoActionBar"
        android:name="android.support.PARENT_ACTIVITY"
        android:value="com.com.com.com.MainActivity" />
</activity>

并尝试更改工具栏,如:

Toolbar toolbar = new Toolbar(this);
toolbar.setBackgroundColor(getResources().getColor(R.color.light_blue));
setSupportActionBar(toolbar);

但仍然得到

此活动已经有一个由窗口装饰提供的操作栏。 请勿在主题中请求Window.FEATURE_ACTION_BAR并将windowActionBar设置为false以使用工具栏。

我甚至尝试过getSupportActionBar().hide(); 但仍然无法正常工作。

XML:

<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:tools="http://schemas.android.com/tools" android:layout_width="match_parent"
    android:layout_height="match_parent" android:paddingLeft="@dimen/activity_horizontal_margin"
    android:paddingRight="@dimen/activity_horizontal_margin"
    android:paddingTop="@dimen/activity_vertical_margin"
    android:paddingBottom="@dimen/activity_vertical_margin"
    tools:context="com.com.com.com.SettingsActivity"
    android:id="@+id/settings_activity">
</RelativeLayout>

基本上,我想要的是保持我的全局主题,只是在其中一个活动中更改工具栏颜色。 这就是为什么我不在xml文件中创建工具栏,我以编程方式创建它,添加背景颜色并想要设置它。


Can anyone please, explain me, why my toolbar doesn't change its color even though I created another style like:

<style name="AppTheme.NoActionBar">
    <item name="windowActionBar">false</item>
    <item name="windowNoTitle">false</item>
</style>

added it in my manifest file like:

<activity
    android:name=".SettingsActivity"
    android:label="@string/title_activity_settings"
    android:parentActivityName=".MainActivity">
    <meta-data
        android:theme="@style/AppTheme.NoActionBar"
        android:name="android.support.PARENT_ACTIVITY"
        android:value="com.com.com.com.MainActivity" />
</activity>

and try to change the toolbar like:

Toolbar toolbar = new Toolbar(this);
toolbar.setBackgroundColor(getResources().getColor(R.color.light_blue));
setSupportActionBar(toolbar);

but still get

This Activity already has an action bar supplied by the window decor. Do not request Window.FEATURE_ACTION_BAR and set windowActionBar to false in your theme to use a Toolbar instead.

I even tried to getSupportActionBar().hide(); but still doesn't work.

XML :

<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:tools="http://schemas.android.com/tools" android:layout_width="match_parent"
    android:layout_height="match_parent" android:paddingLeft="@dimen/activity_horizontal_margin"
    android:paddingRight="@dimen/activity_horizontal_margin"
    android:paddingTop="@dimen/activity_vertical_margin"
    android:paddingBottom="@dimen/activity_vertical_margin"
    tools:context="com.com.com.com.SettingsActivity"
    android:id="@+id/settings_activity">
</RelativeLayout>

Basically, what I want is to keep my global theme and just change toolbar color in one of the activities. That is why I don't create a toolbar inside xml file, I create it programmatically, add background color and want to set it.

最满意答案

你需要在meta-data标签之外取下android:theme="@style/AppTheme.NoActionBar"

  <activity
        android:name=".SettingsActivity"
        android:label="@string/title_activity_settings"
        android:theme="@style/AppTheme.NoActionBar"
        android:parentActivityName=".MainActivity">
        <meta-data
            android:name="android.support.PARENT_ACTIVITY"
            android:value="net.noorr.menote.menote.MainActivity" />
    </activity>

在java代码中:

Toolbar toolbar = (Toolbar) findViewById(R.id.yourToolbarId);
toolbar.setBackgroundColor(getResources().getColor(R.color.light_blue));
setSupportActionBar(toolbar);

You need to take off android:theme="@style/AppTheme.NoActionBar" outside the meta-data tag :

  <activity
        android:name=".SettingsActivity"
        android:label="@string/title_activity_settings"
        android:theme="@style/AppTheme.NoActionBar"
        android:parentActivityName=".MainActivity">
        <meta-data
            android:name="android.support.PARENT_ACTIVITY"
            android:value="net.noorr.menote.menote.MainActivity" />
    </activity>

And in java code:

Toolbar toolbar = (Toolbar) findViewById(R.id.yourToolbarId);
toolbar.setBackgroundColor(getResources().getColor(R.color.light_blue));
setSupportActionBar(toolbar);
