程序之美

在这里插入图片描述

今天在github上下载了一个工程导入到本地,编译,就报如下错误:

Caused by: android.view.InflateException: Binary XML file line #8: Binary XML file line #8: Error inflating class

        at com.android.internal.os.ZygoteInit.main(ZygoteInit.java:616) 

经过多方研究,发现引起上述问题的主要有如下原因:

  1. 引用类名问题:自定义了一个View,用于布局文件中,假设包名为com.example.cc,类名叫CameraView,这个时候在XML作为布局元素引用的话,必须使用完整路径名,也就是包名加类名来引用,用com.example.cc.CameraView来进行引用。

    2.构造函数问题:自定义一个View,必须派生实现基类View的三个构造函数

    CameraView(Context context) //Simple constructor to use when creating a view from code

    CameraView(Context context, AttributeSet attrs) //Constructor that is called when inflating a view from XML

    CameraView(Context context, AttributeSet attrs, int defStyle) //Perform inflation from XML and apply a class-specific base style

我的就是第二个问题引起的,增加如下构造函数问题解决。

	public CameraView(Context context) {
		super(context);
		initCameraView(context);
	}

	public CameraView(Context context, AttributeSet attrs) {
		super(context, attrs);
		initCameraView(context);
	}
	public CameraView(Context context, AttributeSet attrs, int defStyle) {
		super(context, attrs, defStyle);     //Perform inflation from XML and apply a class-specific base style
		initCameraView(context);

	}

就此记下,希望能够帮助到遇到和我同样的问题,仍然在迷茫中的小伙伴。你们的进步,是我最大的幸福。
