到目前为止，我正在开发的应用程序运行良好，直到我添加了一些新活动并尝试对主题进行了一些更改。
以下是我的styles.xml 文件。我查看了其他结果，并在 AppTheme 中添加了一个父项，因为我之前收到了关于 AppCompat 的错误。我还让 AppTheme 成为 NoActionBar 的父级。我注意到的一件事是，当我应用 AppBarOverlay 来注册用户活动时它会崩溃，而当我应用其他时它不会。无论如何，主要活动正在崩溃。
<resources>
<!-- Base application theme. -->
<style name="AppTheme" parent="Theme.AppCompat.Light.DarkActionBar">
<!-- Customize your theme here. -->
<item name="colorPrimary">@color/colorPrimary</item>
<item name="colorPrimaryDark">@color/colorPrimaryDark</item>
<item name="colorAccent">@color/colorAccent</item>
</style>
<style name="AppTheme.NoActionBar" parent ="AppTheme">
<item name="windowActionBar">false</item>
<item name="windowNoTitle">true</item>
</style>
<style name="AppTheme.AppBarOverlay" parent="ThemeOverlay.AppCompat.Dark.ActionBar" />
<style name="AppTheme.PopupOverlay" parent="ThemeOverlay.AppCompat.Light" />
</resources>
以下是 Android 清单文件：
<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="com.ati.activate">
<application
android:allowBackup="true"
android:icon="@drawable/footprintblue"
android:label="@string/app_name"
android:roundIcon="@drawable/footprintgreen"
android:theme="@style/AppTheme"
android:supportsRtl="true">
<activity android:name=".UserManagement.LoginActivity"
android:theme="@style/AppTheme.NoActionBar">
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
</activity>
<activity android:name=".UserManagement.RegisterUserActivity"
android:label="@string/app_name"
android:theme="@style/AppTheme.AppBarOverlay">
</activity>
<activity
android:name=".MainActivity"
android:label="@string/app_name"
android:theme="@style/AppTheme">
</activity>
</application>
</manifest>
我已将 AppTheme 应用于 android，然后将所需的主题覆盖到其他活动。注意：登录屏幕工作并使用 AppTheme.NoTitleBar，注册用户在没有 AppBarOverLay 主题的情况下工作，但在使用此主题时崩溃。
这是我的 activity_main.xml 文件
<?xml version="1.0" encoding="utf-8"?>
<android.support.design.widget.CoordinatorLayout xmlns:android="http://schemas.android.com/apk/res/android"

android:layout_width="match_parent"
android:layout_height="match_parent"
android:fitsSystemWindows="true"

<android.support.design.widget.AppBarLayout
android:id="@+id/appbar"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:paddingTop="@dimen/appbar_padding_top"
android:theme="@style/AppTheme.AppBarOverlay">
<!--android:paddingTop="@dimen/appbar_padding_top"-->
<android.support.v7.widget.Toolbar
android:id="@+id/toolbar"
android:layout_width="match_parent"
android:layout_height="?attr/actionBarSize"
app:popupTheme="@style/AppTheme.PopupOverlay"
app:layout_scrollFlags="scroll|enterAlways">
</android.support.v7.widget.Toolbar>
<android.support.design.widget.TabLayout
android:id="@+id/tabs"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:background="@drawable/login_background" />
</android.support.design.widget.AppBarLayout>
<android.support.v4.view.ViewPager
android:id="@+id/pager"
android:layout_width="match_parent"
android:layout_height="match_parent"
app:layout_behavior="@string/appbar_scrolling_view_behavior" />
这是我的 MainActivity.Java 文件的片段：
import android.support.design.widget.TabLayout;
import android.support.v4.app.Fragment;
import android.support.v4.app.FragmentTransaction;
import android.support.v7.app.AppCompatActivity;
import android.support.v4.view.ViewPager;
import android.os.Bundle;
import android.support.v7.widget.Toolbar;
import android.view.Menu;
import android.view.MenuItem;
import com.ati.activate.Fragments.SettingsFragment.AppSettingsFragment;
import com.ati.activate.Fragments.SettingsFragment.ProfileSettingsFragment;
public class MainActivity extends AppCompatActivity{
private AppPagerAdapter mAppPagerAdapter;
private ViewPager mViewPager;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
Toolbar toolbar = (Toolbar) findViewById(R.id.toolbar);
setSupportActionBar(toolbar);
createMenu();
}
我已经尝试了互联网上讨论的所有解决方案，但仍然没有找到任何解决方案。有人可以帮忙吗？提前谢谢你。
以下是使用 AppTheme.AppBarOverlay 打开注册用户活动时的错误：

它适用于对代码的以下更改：
<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>
<item name="android:windowNoTitle">true</item>
<item name="android:windowFullscreen">true</item>
</style>
