java - 如何将 ViewFlipper 中的计时器重置回 0

Question

我正在尝试开发的应用程序有一个 ViewFlipper 和一些对应于 View 的按钮，您单击第三个按钮，ViewFlipper 将 View 更改为第三个图像，问题是一旦我单击该按钮，计时器就不会重置到 0，例如，如果我在第二张图像上停留 4 秒，然后如果我更改为第三张图像，1 秒后 ViewFlipper 将更改为第四张图像，我希望计时器重置回 0，这样它会停留在我更改为 5 秒的 View 上。

这是我的代码:

 @Override
    protected void onCreate(Bundle savedInstanceState) {
        setContentView(R.layout.activity_reservation_page);
        super.onCreate(savedInstanceState);

        viewFlipper=findViewById(R.id.viewflipper);
        int images[]={R.drawable.icon_promotions,R.drawable.icon_promotions,R.drawable.icon_promotions};
        final int numimages=images.length;
        // ADD THE BUTTONS TO THE LINEARLAYOUT
        LinearLayout linearLayout=findViewById(R.id.btn_slide_layout);
        for(int f=0;f<numimages;f++){
                final int num=f;
                ImageView imageView2=new ImageView(this);
                LinearLayout.LayoutParams params2 = new LinearLayout.LayoutParams(
                        LinearLayout.LayoutParams.WRAP_CONTENT, LinearLayout.LayoutParams.WRAP_CONTENT);
                params2.setMargins(15, 0, 0, 0);
                imageView2.setLayoutParams(params2);
                imageView2.setId(f);
                if (f==0){
                    imageView2.setBackgroundResource(R.drawable.icon_message_maincolor);
                }
                else{
                    imageView2.setBackgroundResource(R.drawable.icon_promotions);
                }
                imageView2.setOnClickListener(new View.OnClickListener() {
                    @Override
                    public void onClick(View v) {
                        viewFlipper.setDisplayedChild(num);
                        viewFlipper.setFlipInterval(flippertime);
                    }
                });
                linearLayout.addView(imageView2);
            }

        for(int i=0;i<numimages;i++){
            ImageView imageView=new ImageView(this);
            imageView.setLayoutParams(new RelativeLayout.LayoutParams(RelativeLayout.LayoutParams.MATCH_PARENT, RelativeLayout.LayoutParams.MATCH_PARENT));
            imageView.setBackgroundResource(images[i]);
            flipperimages(imageView);
        }

        viewFlipper.getInAnimation().setAnimationListener(new Animation.AnimationListener() {
            public void onAnimationStart(Animation animation) {
                changeslidericon(viewFlipper.getDisplayedChild());
            }
            public void onAnimationRepeat(Animation animation) {
                changeslidericon(viewFlipper.getDisplayedChild());
            }
            public void onAnimationEnd(Animation animation) {
                changeslidericon(viewFlipper.getDisplayedChild());
            }
            public void changeslidericon(int currentid){
                for(int i=0;i<numimages;i++){
                    if(currentid!=i){
                        findViewById(i).setBackgroundResource(R.drawable.icon_promotions);
                    }
                    else{
                        findViewById(i).setBackgroundResource(R.drawable.icon_message_maincolor);
                    }
                }
            }
        });
    }

    public void flipperimages(View image){

        viewFlipper.addView(image);

        viewFlipper.setFlipInterval(flippertime);
        viewFlipper.setAutoStart(true);

        viewFlipper.setInAnimation(this, R.anim.slide_in_right);
        viewFlipper.setOutAnimation(this, R.anim.slide_out_left);

    }

将此添加到您的 image2 单击监听器:

       viewFlipper.setDisplayedChild(num);
            viewFlipper.stopFlipping();
            viewFlipper.setFlipInterval(flippertime);
            viewFlipper.startFlipping();
