Question

我从这里导入了这个库：

https://github.com/47deg/android-swipelistview

然后我创建了一个带有from和back id的xml文件：

<?xml version="1.0" encoding="utf-8"?>

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:orientation="vertical"
             >

    <RelativeLayout 
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:id="@+id/front"
            android:tag="front" >

            <ImageView
                android:id="@+id/ImageView01"
                android:layout_width="fill_parent"
                android:layout_height="wrap_content"
                android:layout_centerInParent="true"
                 />

            <TextView
                android:id="@+id/TextView01"
                android:layout_width="wrap_content"
                android:layout_height="wrap_content"
                android:layout_alignBottom="@+id/ImageView01"
                android:layout_centerHorizontal="true"
                android:textSize="18sp"
                android:textStyle="bold"
                android:inputType="textMultiLine" />

        </RelativeLayout>


            <LinearLayout
                      android:layout_width="match_parent"
                      android:layout_height="wrap_content"
                      android:orientation="horizontal"
                      android:id="@+id/back"
                     android:tag="back"

                      >

                      <Button
                          android:id="@+id/deleteBtn1"
                          android:layout_width="150dp"
                          android:layout_height="100dp"
                          android:text="Delete" />

                      <Button
                          android:id="@+id/UpdateBtn1"
                          android:layout_width="150dp"
                          android:layout_height="100dp"
                          android:text="Update" />

                  </LinearLayout>

</LinearLayout>

然后我使用swipeListView创建了xml文件：

<?xml version="1.0" encoding="utf-8"?>

   <LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
        android:layout_width="fill_parent"
        android:layout_height="fill_parent"
        android:layout_below="@+id/linearLayout1"
        android:orientation="vertical" >

                <EditText android:id="@+id/EditText01"
                                android:layout_height="wrap_content"
                                android:layout_width="fill_parent"
                                android:hint="Search">                               
                </EditText>

                <ListView android:id="@+id/android:list"
                                android:layout_height="wrap_content"
                                android:layout_width="fill_parent">
                </ListView>


        <main.java.com.fortysevendeg.android.swipelistview.SwipeListView
            xmlns:swipe="http://schemas.android.com/apk/res-auto"
            android:id="@+id/example_lv_list"
            android:listSelector="#00000000"
            android:layout_width="fill_parent"
            android:layout_height="wrap_content"
            swipe:swipeFrontView="@+id/front"
            swipe:swipeBackView="@+id/back"
            swipe:swipeActionLeft="dismiss"
            swipe:swipeCloseAllItemsWhenMoveList="true"
            swipe:swipeMode="both"
            />


    </LinearLayout>

它显示了一个错误：

The following classes could not be instantiated:
- main.java.com.fortysevendeg.android.swipelistview.SwipeListView (Open Class, Show Error Log)
See the Error Log (Window > Show View) for more details.
Tip: Use View.isInEditMode() in your custom views to skip code when shown in Eclipse

    at android.view.LayoutInflater.inflate(LayoutInflater.java:372)

第166行是：

    throw new RuntimeException("Missed attribute swipeFrontView or swipeBackView");

 if (swipeFrontView == 0 || swipeBackView == 0) {
            throw new RuntimeException("Missed attribute swipeFrontView or swipeBackView");
        }

和第121行是：

init(attrs);


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

非常感谢

Adir我认为问题可能是您尝试使用无效的包名称标识符来实例化错误的类。 main.java。的 com.fortysevendeg.android.swipelistview.SwipeListView

从类名中删除main.java。

Xml文件遗漏了属性
