java - 如何扩展和修改不同包 java 中的类 - 里面有解释

Question

我需要修改来自不同包的类中的方法

包结构

Android应用程序 ---

         -- dependencies " materialSheetFab"

materialSheetFab ---

               -- src
                  ...
                     --MaterialSheetAnimation.class

                  ---MaterialSheetFab   

在materialSheetAnimation下，我需要覆盖

public void alignSheetWithFab(View fab) {
    ....

    if (rightDiff != 0) { // need to remove this block of code 
        .....
    }

该方法在MaterialSheetFab中调用

protected void morphIntoSheet(final AnimationListener endListener) {

    // Align sheet's position with FAB
    sheetAnimation.alignSheetWithFab(fab);

问题是materialsheetAnimation中的成员变量是私有(private)的，所以

public class Sample extend MaterialSheetAnimat{
  ......
  @overide 
  public void AlignSheetWithFab(Fab){
     ....
     //remove code 
     // but cant call any instance variable  there all private 
     // sheet is private member // sheet.setX(fab.coord[0]; not possible

即使扩展类也不允许我重写我感兴趣的代码块

Answer 1

Bbut the problem is member variable in the materialsheetAnimation are private so even extending the class doesnt allow me to rewrite the code block am intereested in

这是private成员的定义，您不能覆盖它。
