我很难找出导致我的代码崩溃的原因。到目前为止，我已经搜索了两天，阅读了所有相关文章，并尝试了almos似乎合适的所有提议解决方案，以至于我不得不问自己：
我的应用在启动时崩溃，“运行”选项卡输出以下错误：

我正在使用Android Studio 3.1.4
以下是所有相关文件：
package es.tretornesp.clickerchat;
import android.content.Intent;
import android.graphics.Color;
import android.os.Bundle;
import android.support.design.widget.Snackbar;
import android.support.v7.app.AppCompatActivity;
import android.support.v7.widget.Toolbar;
import android.view.Menu;
import android.view.MenuItem;
import android.view.View;
import android.widget.AdapterView;
import android.widget.ListView;
import android.widget.RelativeLayout;
import com.miguelcatalan.materialsearchview.MaterialSearchView;
import java.util.ArrayList;
public class GroupList extends AppCompatActivity {
private MaterialSearchView searchView;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.group_list);
Toolbar toolbar = (Toolbar) findViewById(R.id.toolbar);
setSupportActionBar(toolbar);
getSupportActionBar().setTitle("Lista de grupos");
toolbar.setTitleTextColor(Color.parseColor("#FFFFFF"));
searchView = (MaterialSearchView) findViewById(R.id.search_view);
}
@Override
public boolean onCreateOptionsMenu(Menu menu) {
getMenuInflater().inflate(R.menu.group_menu_item, menu);
MenuItem item = menu.findItem(R.id.action_search);
searchView.setMenuItem(item);
return true;
}
}
这是group_list.xml
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout
xmlns:android="http://schemas.android.com/apk/res/android"

android:layout_height="fill_parent"
android:layout_below="@+id/toolbar"
android:divider="#806326"
android:id="@+id/listView"

</RelativeLayout>
这是group_menu_item.xml
<?xml version="1.0" encoding="utf-8"?>
<menu xmlns:android="http://schemas.android.com/apk/res/android"

android:id="@+id/action_search"
android:icon="@drawable/image_search_action"
android:orderInCategory="100"
android:title="Buscar..."
app:showAsAction="always"
/>
</menu>
这里是styles.xml
<resources>
<!-- Base application theme. -->
<style name="AppTheme" parent="Base.Theme.AppCompat.Light.DarkActionBar">
<!-- Customize your theme here. -->
<item name="colorPrimary">@color/colorPrimary</item>
<item name="colorPrimaryDark">@color/colorPrimaryDark</item>

<style name="AppTheme.NoActionBar">

<item name="windowNoTitle">true</item>
<item name="android:windowDrawsSystemBarBackgrounds">true</item>
<item name="android:statusBarColor">@android:color/transparent</item>
</style>
</resources>
希望有人可以阐明这里可能发生的情况。
编辑：这是gradle文件，这些文件我照原样发布了。
