Java 单击按钮时，应用程序被强制关闭

我是这样做的按钮组侦听器，但当按钮点击应用程序是强制关闭，我不知道我的代码是什么问题，所以请检查这个

这是我的应用程序项目的完整代码

公共类菜单扩展活动{

                           if(three==button9|| three==button10|| three==button11|| three==button12){

                             }

               };



    button9.setOnClickListener(listener2);

    button12.setOnClickListener(listener2);

               animFadeout1.setAnimationListener(new AnimationListener() {

                    @Override
                    public void onAnimationStart(Animation animation) {
                        // TODO Auto-generated method stub
                    }

                    @Override
                    public void onAnimationRepeat(Animation animation) {
                        // TODO Auto-generated method stub
                    }

                    @Override
                    public void onAnimationEnd(Animation animation) {
                        // TODO Auto-generated method stub
                           ((View) listener2).startAnimation(animFadeout2);
                    }
                });


           animFadeout2.setAnimationListener(new AnimationListener() {

                @Override
                public void onAnimationStart(Animation animation) {
                    // TODO Auto-generated method stub
                }

                @Override
                public void onAnimationRepeat(Animation animation) {
                    // TODO Auto-generated method stub
                }

                @Override
                public void onAnimationEnd(Animation animation) {
                    // TODO Auto-generated method stub
                       ((View) listener2).startAnimation(animFadeout3);
                }
            });


           animFadeout3.setAnimationListener(new AnimationListener() {

                @Override
                public void onAnimationStart(Animation animation) {
                    // TODO Auto-generated method stub
                }

                @Override
                public void onAnimationRepeat(Animation animation) {
                    // TODO Auto-generated method stub
                }

                @Override
                public void onAnimationEnd(Animation animation) {
                    // TODO Auto-generated method stub

                          Intent intent = new Intent( menu.this, play.class);
                          intent.putExtra(KEY_ANIM, target_op);
                          startActivity(intent);
                          menu.this.finish();


                }
            });

我把动画放在那里，所以当listener1按钮组单击时，它将显示淡出动画，当listener1动画结束时，listener2动画显示，依此类推到listener3

这是logcat的

如果我的代码有错误，我很抱歉，因为我被要求在这里更正我的代码，请提前感谢

您正在将

onClickListenner

投射到

视图

，并尝试

启动动画

，这将导致错误

应在视图上调用它：

view.startAnimation(animFadeout1); 

---

代码的其他问题：

由于您使用了所有这些按钮，因此在ClickListener上执行活动将更容易：

public class menu extends Activity implements View.OnClickListener{...}

所有按钮都使用相同的id，因此所有按钮的行为都相同

您需要使用不同的ID，并使它们使用相同的侦听器：

button1= (Button)findViewById(R.id.button_one);   
button1.setOnClickListener(this);          
button2= (Button)findViewById(R.id.button_two); 
button2.setOnClickListener(this);

然后使用开关盒根据按钮id提供不同的逻辑

  @Override
   public void onClick(View view) {
       //To identify the correct widget, use the getId() method on the view argument
       int id = view.getId();
       switch (id) {
           case R.id.button_one:
               //viewOne clicked
               break;
           case R.id.button_two:
               //And so on...
       }
   }

您可以为多个按钮创建一个案例，例如：

case R.id.button_one, R.id.button_two , R.id.button_three, R.id.button_four:

---

此外，您的动画是多余的，良好的编码实践希望您避免重复。

使用LogCat检查与崩溃相关的Java堆栈跟踪：为什么所有按钮都具有相同的id，为什么不使用一个带开关子句的侦听器？为什么要尝试将onClickListener强制转换为视图？@KostasMatrix抱歉，我忘记编辑了 that@Mike是的，然后从那里开始动画，这样我就可以把4个按钮放在一个盒子里，然后我就可以用所有的按钮来开始动画了？
