我创建了自定义视图MyView
:
package com.example;
public class MyView extends View {
public MyView(Context context) {
super(context);
}
}
并在布局xml中使用它:
<com.example.MyView android:id="@+id/imageView"
android:layout_width="fill_parent"
android:layout_height="fill_parent">
</com.example.MyView>
它抛出错误:
09-02 16:43:07.114: ERROR/AndroidRuntime(1387): FATAL EXCEPTION: main
java.lang.RuntimeException: Unable to start activity
ComponentInfo{com.example/com.example.MyActivity}: android.view.InflateException: Binary XML file line #13:

如何解决?

您应该尝试为其工作定义另一个构造函数。
public MyView(Context context, AttributeSet attrs){
super(context, attrs);
}
