Question

我有一个项目列表视图。现在我想构建一个OnItemClickListener。如果用户单击该项目，则会启动新的活动。 Actvity在put.Extra Methode上给出一个带有imagePaths的ArrayList，用于在同一个地方加载图片。但如果我点击项目，不同的图片正在加载。这是代码

MyCompositionView.setOnItemClickListener(new AdapterView.OnItemClickListener() {

        int count = 0;
        ArrayList<String> tmpImgPath = new ArrayList<String>();
        @Override
        public void onItemClick(AdapterView<?> parent, View view, int position, long id) {
            for (int i = 0; i < myList.size(); i++) {
                count++;


                for (int j = 0; j < count; j++) {
                    tmpImgPath.add(myList.get(i).imgPath.get(j));
                }

            }

            if (count == 3) {
                Intent intent = new Intent(MyCompositionsListActivity.this, LayoutForThreeActivity.class);
                intent.putExtra("imgPaths", tmpImgPath);
                startActivity(intent);
            }
        }
    });

我认为我的for循环出了问题！

MyCompositionView.setOnItemClickListener(new AdapterView.OnItemClickListener() {

    int count = 0;
    ArrayList<String> tmpImgPath = new ArrayList<String>();
    @Override
    public void onItemClick(AdapterView<?> parent, View view, int position, long id) {
        //for (int i = 0; i < myList.size(); i++) {
           // count++;


            //for (int j = 0; j < count; j++) {
               // tmpImgPath.add(myList.get(i).imgPath.get(j));
            //}

        //}

       // if (count == 3) {
            Intent intent = new Intent(MyCompositionsListActivity.this, LayoutForThreeActivity.class);
            intent.putExtra("imgPaths", myList.get(position).imgPath);
            startActivity(intent);
       // }
    }
});
