错误在此行

setContentView(R.layout.activity_home);

这是home_activity.xml代码

我已经查看了与此错误相关的所有以前的问题，但无法解决错误，请在这方面帮助我。。。提前感谢

我已经上传了代码，并提到了它的位置错误现在不知道如何解决这个

Answer 1

您的<fragment>标记缺少其android:name属性。这是告诉充气器使用哪一个Fragment类。

看起来您可能不小心将此属性放在了早期的<ImageView>标记上。

<ImageView
android:layout_weight="1"
android:src="@drawable/ic_pin_drop_black_24dp"
android:layout_width="0dp"
android:layout_height="wrap_content"
android:name="com.google.android.gms.location.places.ui.PlaceAutocompleteFragment"/>
<fragment
android:id="@+id/place_location"
android:layout_weight="5"
android:layout_width="0dp"
android:layout_height="wrap_content"/>

如果我是对的，你会想要这个：

<ImageView
android:layout_weight="1"
android:src="@drawable/ic_pin_drop_black_24dp"
android:layout_width="0dp"
android:layout_height="wrap_content"/>
<fragment
android:id="@+id/place_location"
android:layout_weight="5"
android:layout_width="0dp"
android:layout_height="wrap_content"
android:name="com.google.android.gms.location.places.ui.PlaceAutocompleteFragment"/>
