创建新活动并用不同的资源填充它

Question

嗨，我是新来的，所以我需要您的帮助。每当我单击列表视图位置时，我都想夸大活动并取决于它的可能性，我可以用不同的图像和文本填充布局。这是代码..谢谢您的帮助

public class WalkFragment extends Fragment {

public WalkFragment() {
    // Required empty public constructor
}

@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
                         Bundle savedInstanceState) {
    final View rootView = inflater.inflate(R.layout.word_list, container, false);
    final ArrayList<word> walk = new ArrayList<>();
    walk.add(new word("Παλιά Πόλη", "Περπάτημα", R.drawable.old_town));
    walk.add(new word("Φορτέτζα", "Περπάτημα", R.drawable.forteza));
    walk.add(new word("Παραλία", "Περπάτημα", R.drawable.paralia));
    walk.add(new word("Δημοτικός Κήπος", "Περπάτημα", R.drawable.khpos));
    walk.add(new word("Περιφεριακό", "Περπάτημα", R.drawable.periferiakos));

    final WordAdapter adapter =
            new WordAdapter(getActivity(), walk);

    final ListView listView = (ListView) rootView.findViewById(R.id.list);

    listView.setAdapter(adapter);

    // Set a click listener to inflate and populate the place_layout and InfoActivity
    //  with a string from strings.xml and an image from drawable
    // when the list item is clicked on
    // the imageView is mImageView and textView is mTextView that i need to
    // populate each time i click on a different position in the listView
    listView.setOnItemClickListener(new AdapterView.OnItemClickListener() {
        @Override
        public void onItemClick(AdapterView<?> adapterView, View view, int position, long l) {
            if (position == 0) {
                Intent infoActivity = new Intent(getContext(), InfoActivity.class);


                startActivity(infoActivity);
            } else if (position == 1) {
                Intent infoActivity = new Intent(getContext(), InfoActivity.class);

                startActivity(infoActivity);
            }

        }
    });

    return rootView;
}
}

Answer 1

1. 创建一个带有imageView和TextView的.xml文件。

2. 用以下内容替换onitemclick内部的所有内容：

   Intent infoActivity = new Intent(getContext(), InfoActivity.class);
   intent.putExtra("position", position);
   startActivity(infoActivity);
   

3. infoActivity的increate（）添加了以下内容：

   int position = getIntent().getIntExtra("position", -1);
   switch (position){
       case 0:
           //set resources for imageview & textview
           break;
       case 1:
           //set resources for imageview & textview
           break;
       .
       .
       .
       .
   
       default:
           //set resources for imageview & textview
           break;
   }

     listview.setOnItemClickListener(new AdapterView.OnItemClickListener() {
            @Override
            public void onItemClick(AdapterView<?> adapterView, View view, int position, long id) {

                switch (position)
                {
                    case 0:
                         Intent infoActivity = new Intent(getContext(), InfoActivity.class);
                         intent.putExtra("position", position);
                         startActivity(infoActivity);
                        break;
                    case 1:
                         Intent infoActivity = new Intent(getContext(), SecondActivity.class);
                         intent.putExtra("position", position);
                         startActivity(infoActivity);
                        break;
                    case 2:
                         Intent infoActivity = new Intent(getContext(), ThirdActivity.class);
                         intent.putExtra("position", position);
                         startActivity(infoActivity);
                        break;
                    case 3:
                        Intent infoActivity = new Intent(getContext(), FourthActivity.class);
                        intent.putExtra("position", position);
                        startActivity(infoActivity);
                        break;
                    default:
                        //set resources for imageview & textview
                        break;
                }
            }
        });
