Question

基本上我有一个阵列有2个图像，好像现在但最终会有更多。每隔几秒就从阵列切换器发送图像。我坚持使用onClick方法。当用户点击该图像时，最终目标就是打开新的Activity类。每个图像都有自己的Activity类，因此当用户点击它时，它应该定向到该特定的类。

我昨天得到了一些帮助

public void onClick(View v) {
       Intent n = null;
       int id = v.getId();
       switch (id){
           case R.id.someId:
                n = new Intent(getActivity(), FragMent1.class);
                break;
           case R.id.someOtherId:
                n = new Intent(getActivity(), FragMent2.class);
                break;
        }

我可以将第一个案例陈述设置为＆＃34; R.id.textSwitcher＆＃34;但第二是问题。因为我希望图像动画在一个地方，新的R.id ...意味着新的位置也是新的＆＃34; mSwitcher1.setOnClickListener（新的View.OnClickListener（）＆＃34;

public class Animation extends Fragment implements AnimationListener {

    public HomeAnimation(){}
    private static boolean flag = false;
     Animation anim;
     private Handler handler;
     public ImageSwitcher mSwitcher,mSwitcher1;

    int textToShow[] = {R.drawable.dabangg, R.drawable.car };

    int messageCount = textToShow.length;
    int currentIndex = -1;
    @Override
    public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
       View v = inflater.inflate(R.layout.imgswitch, container, false);
        mSwitcher = (ImageSwitcher) v.findViewById(R.id.imageSwitcher1);
        mSwitcher.setFactory(mFactory);
        anim = AnimationUtils.loadAnimation(getActivity(),R.anim.fade_in);

        mSwitcher.setOnClickListener(new View.OnClickListener() {
            public void onClick(View v) {
                Intent n = null;
                 int id = v.getId();
                // Fragment fragment = null;
                //Bundle args = new Bundle();
                switch (v.getId()){
                case 0:
                    n = new Intent(getActivity(), Fragment1.class);
                    getActivity().startActivity(n);
                    break;
                case 1:
                    n = new Intent(getActivity(), Fragment2.class);
                    getActivity().startActivity(n);
                    break;
                }
            }
        });
        // set animation listener
        anim.setAnimationListener(this);
        return v;    
    }

public void updateTextView() {

    int maxIndex = textToShow.length;
    Random random = new Random();
    int generatedIndex = random.nextInt(maxIndex);
    mSwitcher.setImageResource(textToShow[generatedIndex]);

}

以下是我更新的内容，如果有人需要它

public void updateTextView() {

        int maxIndex = textToShow.length;
        Random random = new Random();
        final int generatedIndex = random.nextInt(maxIndex);
        mSwitcher.setImageResource(textToShow[generatedIndex]);
        mSwitcher.setOnClickListener(new View.OnClickListener() {
            public void onClick(View v) {
                Intent n = null;

                 switch(generatedIndex){
                 case 0:
                     n = new Intent(getActivity(), Fragment1.class);
                       getActivity().startActivity(n);
                       break;

                 case 1:
                      n = new Intent(getActivity(), Fragment2.class);
                       getActivity().startActivity(n);
                       break;
                 case 2:
                       n = new Intent(getActivity(), Fragment3.class);
                       getActivity().startActivity(n);
                       break;

                }
            }
         });

我现在没有时间对此进行测试，而且我不完全确定我明白你的问题在哪里，但试试这个，看看它是不是你想要的。我会在代码中添加注释

mSwitcher.setOnClickListener(new View.OnClickListener() {
        public void onClick(View v) {
            Intent n = null;
             int id = v.getId();
            // Fragment fragment = null;
            //Bundle args = new Bundle();
            switch (v.getId()){
            case 0:
              /* 
                 below should give you the index for the displayed image
                 you can compare this to the ids in your array using the index
              */
               if (v.getDisplayedChild() == 0) { // if 1st image in array do this
                   n = new Intent(getActivity(), Fragment1.class);
                   getActivity().startActivity(n);
               }
               if (v.getDisplayedChild() == 1) { // if 2nd image in array do this
                   n = new Intent(getActivity(), Fragment2.class);
                   getActivity().startActivity(n);
               }
              break;
