不能在自定义通知中包含简单视图？

Posted 2021-05-04

在我的app我正在建立一个定制的notification与big view约150dp。

layout如下

<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:tools="http://schemas.android.com/tools"
    android:layout_width="match_parent"
    android:layout_height="match_parent" >

    <ImageView
        android:id="@+id/imagenotileft"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content" />

    <TextView
        android:id="@+id/title"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_toRightOf="@+id/imagenotileft" />

     <View
      android:id="@+id/view"
      android:layout_width="365dp"
      android:layout_height="@dimen/dp_2"
      android:layout_marginTop="@dimen/dp_23"
      android:layout_centerHorizontal="true"
      android:layout_below="@+id/title"
      android:background="@color/comunica_app_light_grey" />

    <TextView
        android:id="@+id/text"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_below="@+id/view"
        android:layout_toRightOf="@+id/imagenotileft" />

    <ImageView
        android:id="@+id/imagenotiright"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_alignParentRight="true"
        android:padding="10dp" />

</RelativeLayout>

当调用创建View函数时，app组件导致notification崩溃.code部分没有任何问题，因为它没有View组件完全膨胀。

错误期间的日志如下所示。

我无法弄清楚从日志中导致这种情况的原因。

请提供解决方案。

答案

您已为该视图添加了此ID

 android:id="@+id/title"

并且以下id未分配给任何视图

@+id/send_date

这可能是个问题

另一答案

您必须添加自定义视图所需的所有构造函数。如果你使用android studio找到Code-> Generate，然后是“constructor”，然后检查所有可用的构造函数，在下一个窗口中你必须取消选中所有类属性，然后IDE为你生成这个构造函数。

public class CustomView extends View {    
    public CustomView(Context context) {
        super(context);
    }

    public CustomView(Context context, AttributeSet attrs) {
        super(context, attrs);
        init(attrs);
    }

    public CustomView(Context context, AttributeSet attrs, int defStyleAttr) {
        super(context, attrs, defStyleAttr);
        init(attrs);
    }
}
