Question

嗨，我是新生的，所以我需要你的帮助。每次我点击listView位置我想要膨胀活动并且根据其可能性，我想用不同的图像和文本填充布局。这是代码..感谢您的帮助

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

使用ImageView和TextView为您的活动创建一个.xml文件。

使用以下内容替换onItemClick中的所有内容：

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

在InfoActivity的onCreate（）内添加：

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;
}

请参考这个答案

     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;

                }

            }
        });

创建新活动并使用不同的资源填充它
