@ViewDebug.ExportedProperty注解

文章目录

1. 1. 使用

使用`@ViewDebug.ExportedProperty`注解，可以在Monitor的Hierarchy Viewer中的调试View属性，可以直接观察注解过的变量和方法的值，实时观察View的状态变化。

使用

• category 指定属性的类别，比如measurement,layout,drawing等。
• resolveId 当resolveId为true时，变量或方法的值为int数据，那么这个值会被转换成Android对应的资源名称
• mapping 可以将int值映射成指定的字符串
• indexMapping 可以将数组的序号映射成指定的字符串

  @ViewDebug.ExportedProperty(category = "seniorzhai")
  int x = 1;
  
  @Override
  @ViewDebug.ExportedProperty(category = "seniorzhai")
  public boolean isFocused() {
    return true;
  }
  
  @Override
  @ViewDebug.ExportedProperty(category = "seniorzhai")
  public boolean isFocused() {
    return true;
  }
  
  @ViewDebug.ExportedProperty(category = "seniorzhai",resolveld = true)
  int b = R.id.no;
  
  @Override
  @ViewDebug.ExportedProperty(category = "seniorzhai",
      mapping = {
                    @ViewDebug.IntToString(from = VISIBLE, to = "SENIOR_VISIBLE"),
                    @ViewDebug.IntToString(from = INVISIBLE, to = "SENIOR_INVISIBLE"),
                    @ViewDebug.IntToString(from = GONE, to = "SENIOR_GONE")
                })
  public int getVisibility() {
    return super.getVisibility();    
  }
  
  @ViewDebug.ExportedProperty(category = "seniorzhai",
  indexMapping = {
                    @ViewDebug.IntToString(from = 0, to = "SENIOR_FIRST"),            @ViewDebug.IntToString(from = 1, to = "SENIOR_SECOND"),
                    @ViewDebug.IntToString(from = 2, to = "SENIOR_THIRD")
                  })
  int[] elements = new int[] {123, 223, 323};
