活动中的工具栏
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
Toolbar toolbar = (Toolbar) findViewById(R.id.toolbar);
setSupportActionBar(toolbar);
}
这是我添加工具栏的xml文件
<LinearLayout
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_gravity="top"
android:orientation="vertical"
xmlns:android="http://schemas.android.com/apk/res/android">
<android.support.v7.widget.Toolbar
xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:background="@color/primaryColor"
android:paddingTop="@dimen/app_bar_top_padding"
app:popupTheme="@style/ThemeOverlay.AppCompat.Dark"
app:theme="@style/MyCustomToolBarTheme">
</android.support.v7.widget.Toolbar>
<FrameLayout
android:layout_width="match_parent"
android:layout_height="match_parent">
<!-- **** Place Your Content Here **** -->
<View
android:layout_width="match_parent"
android:layout_height="5dp"
android:background="@drawable/shadow" />
</FrameLayout>
</LinearLayout>
我在logcat java.lang.ClassCastException中得到这个:android.widget.LinearLayout无法强制转换为android.support.v7.widget.Toolbar
我怎样才能摆脱这个错误？
