一个 ArrayList 项目的多个意图

Question

我有一个包含几家酒店详细信息的 ArrayList，我想做的是点击地址打开地图意图，然后点击 phone 数字打开 phone.

如有任何帮助，我们将不胜感激。这些是代码片段。

@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
    // Inflate the layout for this fragment
    View rootView = inflater.inflate(R.layout.item_list, container, false);

    final ArrayList<pojo> pojoArrayList = new ArrayList<pojo>();
    pojoArrayList.add(new pojo(getString(R.string.hotel_one), R.drawable.hotel_one, R.drawable.gradient_splash, R.drawable.ic_map_, getString(R.string.hotel_one_location), R.drawable.ic_phone_solid, getString(R.string.hotel_one_phone)));
    pojoArrayList.add(new pojo(getString(R.string.hotel_two), R.drawable.hotel_tow, R.drawable.gradient_splash, R.drawable.ic_map_, getString(R.string.hotel_two_location), R.drawable.ic_phone_solid,getString(R.string.hotel_two_phone)));
    pojoArrayList.add(new pojo(getString(R.string.hotel_three), R.drawable.hotel_three, R.drawable.gradient_splash, R.drawable.ic_map_, getString(R.string.hotel_three_location), R.drawable.ic_phone_solid,getString(R.string.hotel_three_phone)));
    pojoArrayList.add(new pojo(getString(R.string.hotel_four), R.drawable.hotel_four, R.drawable.gradient_splash, R.drawable.ic_map_, getString(R.string.hotel_four_location), R.drawable.ic_phone_solid,getString(R.string.hotel_four_phone)));
    pojoArrayList.add(new pojo(getString(R.string.hotel_five), R.drawable.hotel_five, R.drawable.gradient_splash, R.drawable.ic_map_, getString(R.string.hotel_five_location), R.drawable.ic_phone_solid,getString(R.string.hotel_five_phone)));

    HotelsAdapter adapter = new HotelsAdapter(getActivity(), pojoArrayList);
    ListView listViewItems = (ListView) rootView.findViewById(R.id.list);
    listViewItems.setAdapter(adapter);

    listViewItems.setOnItemClickListener(new AdapterView.OnItemClickListener() {
        @Override
        public void onItemClick(AdapterView<?> adapterView, View view, int position, long l) {
            pojo pojo = pojoArrayList.get(position);

            if (position == 0) {
                Intent callIntent = new Intent(Intent.ACTION_DIAL);
                callIntent.setData(Uri.parse("tel: +31202246280"));
                startActivity(callIntent);
            } else if (position == 1) {
                Intent callIntent = new Intent(Intent.ACTION_DIAL);
                callIntent.setData(Uri.parse("tel: +31 20 506 3715"));
                startActivity(callIntent);
            } else if (position == 2){
                Intent callIntent = new Intent(Intent.ACTION_DIAL);
                callIntent.setData(Uri.parse("tel: +31 20 881 2595"));
                startActivity(callIntent);
            } else if (position == 3) {
                Intent callIntent = new Intent(Intent.ACTION_DIAL);
                callIntent.setData(Uri.parse("tel: +31 20 665 1171"));
                startActivity(callIntent);
            } else {
                Intent callIntent = new Intent(Intent.ACTION_DIAL);
                callIntent.setData(Uri.parse("tel: +31 20 210 3535"));
                startActivity(callIntent);
            }
        }
    });

    return rootView;
}

这是它的布局：

适配器：

    public class HotelsAdapter extends ArrayAdapter<pojo>{
    public HotelsAdapter(@NonNull Context context, ArrayList<pojo> pojo) {
        super(context, 0, pojo);
    }
    @NonNull
    @Override
    public View getView(int position, @Nullable View convertView, @NonNull ViewGroup parent) {
        View listView = convertView;
        if (listView == null){
            listView = LayoutInflater.from(getContext()).inflate(R.layout.hotel_items, parent, false);
        }
        pojo currentItem = getItem(position);

        ImageView backgroundImage = (ImageView) listView.findViewById(R.id.category_image);
        backgroundImage.setImageResource(currentItem.getImageResource());

        TextView categoryHeader = (TextView) listView.findViewById(R.id.category_header);
        categoryHeader.setText(currentItem.getHeaderResource());

        View categoryGradient  = (View) listView.findViewById(R.id.grad);
        categoryGradient.setBackgroundResource(currentItem.getGradientResource());

        ImageView locationIcon = (ImageView) listView.findViewById(R.id.location_icon);
        locationIcon.setImageResource(currentItem.getLocationIconID());

        TextView addressView = (TextView) listView.findViewById(R.id.location_data);
        addressView.setText(currentItem.getAddressID());

        ImageView phoneIcon = (ImageView) listView.findViewById(R.id.phone_icon);
        phoneIcon.setImageResource(currentItem.getPhoneIconID());

        TextView phoneView = (TextView) listView.findViewById(R.id.phone_data);
        phoneView.setText(currentItem.getPhoneID());

        return listView;
    }
}

到目前为止，我只有一个打开拨号器的意图。我如何 select location 部分和 phone 部分分开，并且对两者有不同的意图？

Answer 1

试试这个

First i suggest to use Recylerview because Recylerview is the advanced one.

在此处检查：https://developer.android.com/reference/android/support/v7/widget/RecyclerView

listViewItems.setOnItemClickListener(new AdapterView.OnItemClickListener() {
    @Override
    public void onItemClick(AdapterView<?> adapterView, View view, int position, long l) {
        pojo pojo = pojoArrayList.get(position);

        LinearLayout linear_phone = view.findViewById(R.id.phone_layout);
        linear_phone.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View view) {
             Intent callIntent = new Intent(Intent.ACTION_DIAL);
            callIntent.setData(Uri.parse(pojo.getPhoneID()));
            startActivity(callIntent);

        }
    });

     LinearLayout linear_location = view.findViewById(R.id.location_layout);
        linear_phone.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View view) {
             //Location Intent Code

        }
    });


    }
});

Answer 2

试试这个，

public class HotelsAdapter extends ArrayAdapter<pojo> {
private Context mContext;

public HotelsAdapter(@NonNull Context context, ArrayList<pojo> pojo) {
    super(context, 0, pojo);
    this.mContext = context;
}

@NonNull
@Override
public View getView(int position, @Nullable View convertView, @NonNull ViewGroup parent) {
    View listView = convertView;
    if (listView == null) {
        listView = LayoutInflater.from(getContext()).inflate(R.layout.hotel_items, parent, false);
    }
    final pojo currentItem = getItem(position);

    ImageView backgroundImage = (ImageView) listView.findViewById(R.id.category_image);
    backgroundImage.setImageResource(currentItem.getImageResource());

    TextView categoryHeader = (TextView) listView.findViewById(R.id.category_header);
    categoryHeader.setText(currentItem.getHeaderResource());

    View categoryGradient = (View) listView.findViewById(R.id.grad);
    categoryGradient.setBackgroundResource(currentItem.getGradientResource());

    ImageView locationIcon = (ImageView) listView.findViewById(R.id.location_icon);
    locationIcon.setImageResource(currentItem.getLocationIconID());

    TextView addressView = (TextView) listView.findViewById(R.id.location_data);
    addressView.setText(currentItem.getAddressID());

    ImageView phoneIcon = (ImageView) listView.findViewById(R.id.phone_icon);
    phoneIcon.setImageResource(currentItem.getPhoneIconID());

    TextView phoneView = (TextView) listView.findViewById(R.id.phone_data);
    phoneView.setText(currentItem.getPhoneID());

    // add this code in your adapter

    LinearLayout locationLayout = (LinearLayout) listView.findViewById(R.id.location_layout)
    locationLayout.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View v) {
            Intent geoIntent = new Intent(android.content.Intent.ACTION_VIEW, Uri
                    .parse("geo:0,0?q=" + currentItem.getAddressID()));
            mContext.startActivity(geoIntent);
        }
    });

    LinearLayout phoneLayout = (LinearLayout) listView.findViewById(R.id.phone_layout)
    locationLayout.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View v) {
            Intent callIntent = new Intent(Intent.ACTION_DIAL);
            callIntent.setData(Uri.parse("tel: " + currentItem.getPhoneID()));
            mContext.startActivity(callIntent);
        }
    });


    return listView;
}
}

并删除 listview.onitemClicklistener();

Answer 3

如果您不希望整个列表项都可以点击，而是希望列表中有可点击的元素，您应该实现自定义侦听器

创建一个侦听器接口，为每个应该可点击的单独子视图指定一个方法，在您的 Activity/Fragment 中实现它，然后将它传递给您的自定义列表适配器。

您的自定义适配器随后将根据单击的字段调用侦听器的方法。

示例界面

public interface HotelListClickListener {
    void onAddressClicked(Pojo item);
    void onPhoneClicked(Pojo item);
    ...
}

然后您应该修改您的 HotelsAdapter 以在某个点接收侦听器（构造函数，或 Setter），然后在您的 getView 方法中调用每个适当的方法。

public View getView(int position, @Nullable View convertView, @NonNull ViewGroup parent) {
    ...
    Pojo currentItem = getItem(position);

    TextView addressView = (TextView) listView.findViewById(R.id.location_data);
    addressView.setText(currentItem.getAddressID());
    addressView.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View view) {
            if(listener != null)
                listener.onAddressClicked(currentItem);
        }
    });

    TextView phoneView = (TextView) listView.findViewById(R.id.phone_data);
    phoneView.setText(currentItem.getPhoneID());
    phoneView.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View view) {
            if(listener != null)
                listener.onPhoneClicked(currentItem);
        }
    });
    ...
}

最后，在您的 Activity/Fragment 中，您将创建一个全局侦听器，该侦听器将在单击特定子视图时接收适当的 POJO，然后处理被单击的任何元素。

HotelListClickListener listener = new HotelListClickListener() {
    @Override
    public void onAddressClicked(Pojo item) {
        // Show map view based on item's address
    }
    @Override
    public void onPhoneClicked(Pojo item) {
        // Call number of item that was clicked
    }
};

HotelsAdapter adapter = new HotelsAdapter(getActivity(), pojoArrayList, listener);

Answer 4

为 phoneView 和 addressView 添加 View.Onclicklistener

public class HotelsAdapter extends ArrayAdapter<pojo>{
    public HotelsAdapter(@NonNull Context context, ArrayList<pojo> pojo) {
        super(context, 0, pojo);
    }
    @NonNull
    @Override
    public View getView(int position, @Nullable View convertView, @NonNull ViewGroup parent) {
        /****your code*****/

        //add listener
        addressView.setOnClickListener(mClickListener);
        phoneView.setOnClickListener(mClickListener);
        return listView;
    }
    //add View.Onclicklistener for phoneView and addressView
    private OnClickListener mClickListener;
    public void setOptionClickListener(OnClickListener listener) {
        this.mClickListener = listener;
    }
}

@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
    // Inflate the layout for this fragment
    View rootView = inflater.inflate(R.layout.item_list, container, false);

    final ArrayList<pojo> pojoArrayList = new ArrayList<pojo>();
    pojoArrayList.add(new pojo(getString(R.string.hotel_one), R.drawable.hotel_one, R.drawable.gradient_splash, R.drawable.ic_map_, getString(R.string.hotel_one_location), R.drawable.ic_phone_solid, getString(R.string.hotel_one_phone)));
    pojoArrayList.add(new pojo(getString(R.string.hotel_two), R.drawable.hotel_tow, R.drawable.gradient_splash, R.drawable.ic_map_, getString(R.string.hotel_two_location), R.drawable.ic_phone_solid,getString(R.string.hotel_two_phone)));
    pojoArrayList.add(new pojo(getString(R.string.hotel_three), R.drawable.hotel_three, R.drawable.gradient_splash, R.drawable.ic_map_, getString(R.string.hotel_three_location), R.drawable.ic_phone_solid,getString(R.string.hotel_three_phone)));
    pojoArrayList.add(new pojo(getString(R.string.hotel_four), R.drawable.hotel_four, R.drawable.gradient_splash, R.drawable.ic_map_, getString(R.string.hotel_four_location), R.drawable.ic_phone_solid,getString(R.string.hotel_four_phone)));
    pojoArrayList.add(new pojo(getString(R.string.hotel_five), R.drawable.hotel_five, R.drawable.gradient_splash, R.drawable.ic_map_, getString(R.string.hotel_five_location), R.drawable.ic_phone_solid,getString(R.string.hotel_five_phone)));

    HotelsAdapter adapter = new HotelsAdapter(getActivity(), pojoArrayList);
    ListView listViewItems = (ListView) rootView.findViewById(R.id.list);
    listViewItems.setAdapter(adapter);
    //when you click list's item
    pojo currentTarget;
    listViewItems.setOnItemClickListener(new AdapterView.OnItemClickListener() {
        @Override
        public void onItemClick(AdapterView<?> adapterView, View view, int position, long l) {
            pojo pojo = pojoArrayList.get(position);
            currentTarget = pojo
            if (position == 0) {
                Intent callIntent = new Intent(Intent.ACTION_DIAL);
                callIntent.setData(Uri.parse("tel: +31202246280"));
                startActivity(callIntent);
            } else if (position == 1) {
                Intent callIntent = new Intent(Intent.ACTION_DIAL);
                callIntent.setData(Uri.parse("tel: +31 20 506 3715"));
                startActivity(callIntent);
            } else if (position == 2){
                Intent callIntent = new Intent(Intent.ACTION_DIAL);
                callIntent.setData(Uri.parse("tel: +31 20 881 2595"));
                startActivity(callIntent);
            } else if (position == 3) {
                Intent callIntent = new Intent(Intent.ACTION_DIAL);
                callIntent.setData(Uri.parse("tel: +31 20 665 1171"));
                startActivity(callIntent);
            } else {
                Intent callIntent = new Intent(Intent.ACTION_DIAL);
                callIntent.setData(Uri.parse("tel: +31 20 210 3535"));
                startActivity(callIntent);
            }

    });
    adapter.setOptionClickListener(new View.OnClickListener() {
        @Override

                    //TODO: currentTarget's data that opens up a map
                    break;
                case R.id.phone_data:

                    break;
            }
        }
    });
    return rootView;
}
