Android 在使用bringToFront（）方法时遇到问题

嗨，朋友们，我是android新手，在我的项目中，我需要在同一位置显示两个布局，并需要在按下按钮时应用旋转动画，我通过在同一位置创建两个布局并使用Layout.bringToFront（）方法实现了同样的效果，但我不知道为什么在某些情况下它可以正确地设置动画，但是bringToFront（）方法不能将我的布局放在前面

 public void bodyClicked()
 {
     System.out.println("Inside Body Clicked...");
     System.out.println("Enevelope boolean value... "+enevelopefocus);
     System.out.println("Body Boolean Value..."+bodyfocus);
     if(!bodyfocus)
        {
            bodyLayout.startAnimation(AnimationUtils.loadAnimation(AddJobNew.this, R.anim.rotate_right));
            fromToRootLayout.startAnimation(AnimationUtils.loadAnimation(AddJobNew.this,R.anim.rotate_left));
            final Handler handler = new Handler();
            handler.postDelayed(new Runnable() {
                @Override
                public void run() {

                    runOnUiThread(new Runnable() {

                        @Override
                        public void run() {
                            // TODO Auto-generated method stub
                            fromToRootLayout.startAnimation(AnimationUtils.loadAnimation(AddJobNew.this, R.anim.rotate_center_after_left));
                            bodyLayout.startAnimation(AnimationUtils.loadAnimation(AddJobNew.this, R.anim.rotate_right_center));
                            bodyLayout.bringToFront();
                            bodyLayout.invalidate();
                            bodyLayout.requestFocus();
                            bodyfocus=true;
                            enevelopefocus=false;
                            System.out.println("Body CLicked Completed...");
                            System.out.println("Enevelope boolean value... "+enevelopefocus);
                            System.out.println("Body Boolean Value..."+bodyfocus);
                            fromToRootLayout.invalidate();
                        }
                    });

                }
            }, 500);
            headerLayout.setVisibility(View.VISIBLE);


        }
 }
 public void enevlopeCLicked()
 {
     System.out.println("Inside Enevelope Clicked...");
     System.out.println("Enevelope boolean value... "+enevelopefocus);
     System.out.println("Body Boolean Value..."+bodyfocus);
     headerLayout1.setVisibility(View.GONE);
        fromBodyLayout.setVisibility(View.GONE);
        if(fromAddressTExtView.getText().toString().length()>0)
        {
            fromAddressTExtView.setVisibility(View.VISIBLE);
            fromTopEditBtn.setVisibility(View.GONE);
            fromcontactpick.setVisibility(View.GONE);
        }
        else
        {
            fromTopEditBtn.setVisibility(View.VISIBLE);
            fromcontactpick.setVisibility(View.VISIBLE);
            fromAddressTExtView.setVisibility(View.GONE);
        }
        if(toAddressTExtView.getText().toString().length()>0)
        {
            toAddressTExtView.setVisibility(View.VISIBLE);
            toBottomEditBtn.setVisibility(View.GONE);
            toContactPick.setVisibility(View.GONE);
        }
        else
        {
            toBottomEditBtn.setVisibility(View.VISIBLE);
            toContactPick.setVisibility(View.VISIBLE);
            toAddressTExtView.setVisibility(View.GONE);
        }

        if(!enevelopefocus)
        {
            fromToRootLayout.startAnimation(AnimationUtils.loadAnimation(AddJobNew.this, R.anim.rotate_left));
            bodyLayout.startAnimation(AnimationUtils.loadAnimation(AddJobNew.this,R.anim.rotate_right));
            final Handler handler = new Handler();
            handler.postDelayed(new Runnable() {
                @Override
                public void run() {
                    runOnUiThread(new Runnable() {

                        @Override
                        public void run() {
                            // TODO Auto-generated method stub
                            bodyLayout.startAnimation(AnimationUtils.loadAnimation(AddJobNew.this, R.anim.rotate_right_center));
                            fromToRootLayout.startAnimation(AnimationUtils.loadAnimation(AddJobNew.this, R.anim.rotate_center_after_left));
                            fromToRootLayout.bringToFront();
                            fromToRootLayout.invalidate();
                            fromToRootLayout.requestFocus();
                            enevelopefocus=true;
                            bodyfocus=false;
                            System.out.println("Enevelope CLicked Completed...");
                            System.out.println("Enevelope boolean value... "+enevelopefocus);
                            System.out.println("Body Boolean Value..."+bodyfocus);
                            bodyLayout.invalidate();
                        }
                    });

                }
            }, 500);
            headerLayout.setVisibility(View.VISIBLE);

 }
 }

在这里，我使用两个标志来表示body和enevelope每当单击特定按钮时，我都会调用bringToFront（）方法。在这里，它会正确调用，标志值也会正确更改，但我不知道在某些情况下，它会自动变为背景 请帮帮我

谢谢

现在解决了问题，我犯的错误是我编写的语句bodyLayout.SetVisibility（View.GONE）中的其他部分代码影响了我的动画，

请显示相关代码。请不要粘贴你所有的代码，只粘贴你正在设置布局动画和使用bringToFront（）的部分。我已经附加了代码片段@SimonHaving Problem当body设置动画时，它会出现在前面并自动消失，每当我再次启动动画时，它的行为就像它在顶部并移动到背景
