Android Toolbar instead of action bar

问题:

I'm trying to use Toolbar instead of ActionBar. In Android 5.0.+ it works but in 4.4 the status bar is placed on top of the Toolbar.

Screenshot:

Layout:

<android.support.v7.widget.Toolbar
    xmlns:app="http://schemas.android.com/apk/res-auto"
    android:id="@+id/toolbar"
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:minHeight="?attr/actionBarSize"   
    app:theme="@style/ThemeOverlay.AppCompat.Dark.ActionBar"     
    app:popupTheme="@style/ThemeOverlay.AppCompat.Light"
    android:background="@color/actionbar_color"/>

Adding Toolbar in OnCreate():

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

回答1:

Add a frameLayout and in its height use @dimen/statusBarHeight. Then you can create an attrs.xml file for each version (normal, v19 and v21). Inside of each attrs.xml put <dimen name="statusBarHeight">25dp</dimen> Change 25dp to 0 in normal, 25 in v19 and 0 in v21. You can create attrs.xml for landscape mode too (values-land, values-land-v19, etc).

<FrameLayout
        android:id="@+id/statusBar"
        android:layout_width="match_parent"
        android:layout_height="@dimen/statusBarHeight"
        android:background="?colorPrimaryDark"
        android:translationZ="4dp" />

    <android.support.v7.widget.Toolbar xmlns:android="http://schemas.android.com/apk/res/android"
        android:id="@+id/toolbar"
        android:layout_width="match_parent"
        android:layout_height="?attr/actionBarSize"
        android:background="?attr/colorPrimary"
        android:elevation="4dp"
        app:popupTheme="@style/ThemeOverlay.AppCompat.Light"
        app:theme="@style/ThemeOverlay.AppCompat.Dark.ActionBar" />

Add in your XML layout

<android.support.v7.widget.Toolbar
        android:id="@+id/toolbar"
        android:minHeight="?attr/actionBarSize"
        android:background="#2196F3"
        android:layout_width="match_parent"
        android:layout_height="wrap_content">
    </android.support.v7.widget.Toolbar>

In Java

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

回答5:

Try using the ThemeOverlay.NoActionBar theme. It dosen't add the Action Bar

回答6:

Did you change the theme in styles.xml.

<resources>

    <!-- 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>
        <item name="colorAccent">@color/colorAccent</item>
    </style>

</resources>

If you are using a toolbar it should be NoActionBar in the theme.
