java - Xml 文件缺少属性

Question

我从这里导入了库:

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

然后我创建了一个 xml 文件，包含来自和返回的 id:

<?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>

它向我显示错误:

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

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");
        }

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试图通过使用无效的包名称标识符来实例化错误的类。 main.java.com.fortysevendeg.android.swipelistview.SwipeListView

从类名中删除 main.java。
