在我问这里之前,我已经搜索并找到了答案:

long viewId = view.getId();

但是当我在我的代码上使用它时,它仍然是单击整个listview行而不是单击我想要单击的textview。这是我的代码在实现之后回答:

listView.setOnItemClickListener(new OnItemClickListener() {
    public void onItemClick(AdapterView <? > parent, View view, int position, long id) {
        long viewId = view.getId();
        if (viewId == R.id.masterclass_name) {
            Toast.makeText(getApplicationContext(), "masterclass_name clicked", Toast.LENGTH_SHORT).show();
            final Dialog dialog = new Dialog(context);
            dialog.requestWindowFeature(Window.FEATURE_NO_TITLE);
            dialog.getWindow().setBackgroundDrawable(new ColorDrawable(android.graphics.Color.TRANSPARENT));
            dialog.setContentView(R.layout.dialog_popup_pesan_kelas);
            pesan_kelas = (TextView) dialog.findViewById(R.id.pesan_kelas);
            sukses = (TextView) dialog.findViewById(R.id.sukses);
            studio_name = (TextView) dialog.findViewById(R.id.studio_name);
            mohon_hadir = (TextView) dialog.findViewById(R.id.mohon_hadir);
            booking_number = (TextView) dialog.findViewById(R.id.booking_number);
            indentitas_resmi = (TextView) dialog.findViewById(R.id.indentitas_resmi);
            bookbutton = (Button) dialog.findViewById(R.id.bookbutton);
            selesaibutton = (Button) dialog.findViewById(R.id.selesaibutton);
            bookbutton.setOnClickListener(new View.OnClickListener() {@Override
                public void onClick(View v) {
                    pesan_kelas.setVisibility(View.GONE);
                    sukses.setVisibility(View.VISIBLE);
                    bookbutton.setVisibility(View.GONE);
                    selesaibutton.setVisibility(View.VISIBLE);
                    mohon_hadir.setVisibility(View.VISIBLE);
                    booking_number.setVisibility(View.VISIBLE);
                    indentitas_resmi.setVisibility(View.VISIBLE);
                }
            });
            selesaibutton.setOnClickListener(new View.OnClickListener() {@Override
                public void onClick(View v) {
                    dialog.dismiss();
                }
            });
            closedialog = (ImageView) dialog.findViewById(R.id.closeDialog);
            closedialog.setOnClickListener(new View.OnClickListener() {@Override
                public void onClick(View v) {
                    dialog.dismiss();
                }
            });
            studio_name.setOnClickListener(new View.OnClickListener() {@Override
                public void onClick(View v) {
                    Intent intent = new Intent(context, StudioDetail.class);
                    startActivity(intent);
                }
            });
            dialog.show();
        } else if (viewId == R.id.studio_nama) {
            Toast.makeText(getApplicationContext(), "studio_nama clicked", Toast.LENGTH_SHORT).show();
            Intent intent = new Intent(context, StudioDetail.class);
            startActivity(intent);
        } else if (viewId == R.id.trainer_name) {
            Toast.makeText(getApplicationContext(), "trainer_name clicked", Toast.LENGTH_SHORT).show();
        } else if (viewId == R.id.area) {
            Toast.makeText(getApplicationContext(), "area clicked", Toast.LENGTH_SHORT).show();
        } else {
            CariKelasAdapter carikelas = (CariKelasAdapter) parent.getItemAtPosition(position);
            Toast.makeText(getApplicationContext(), carikelas.getMasterclass_name(), Toast.LENGTH_SHORT).show();
            Intent intent = new Intent(context, checkin.class);
            startActivity(intent);
        }
    }
});

我要点击的textview有id:masterclass_name,studio_nama,trainer_name,area。还有一个textview id,但我不想要点击id。因此,只能点击5个textview的4个textview。

每个(来自4个)textview将重定向到不同的结果,例如:一个将显示对话框,另一个将重定向到另一个活动类。

我的代码有什么问题(为什么答案对我的代码不起作用)?如何/ 4正确的代码使4 textview变得可点击?

有关信息,这是我的适配器getView():

@Override
public View getView(int position, View convertView, ViewGroup parent) {
    // convert view = design
    View v = convertView;
    if (v == null) {
        holder = new ViewHolder();
        v = vi.inflate(Resource, null);
        holder.image_carikelas = (ImageView) v.findViewById(R.id.image_carikelas);
        holder.masterclass_name = (TextView) v.findViewById(R.id.masterclass_name);
        holder.studio_nama = (TextView) v.findViewById(R.id.studio_nama);
        holder.trainer_name = (TextView) v.findViewById(R.id.trainer_name);
        holder.area = (TextView) v.findViewById(R.id.area);
        holder.facility = (TextView) v.findViewById(R.id.facility);
        v.setTag(holder);
    } else {
        holder = (ViewHolder) v.getTag();
    }
    //holder.imageview.setImageResource(R.drawable.promo_1);
    new DownloadImageTask(holder.image_carikelas).execute(kelasList.get(position).getImage());
    holder.masterclass_name.setText(kelasList.get(position).getName());
    holder.studio_nama.setText(kelasList.get(position).getStudio_nama());
    holder.trainer_name.setText("Trainer: " + kelasList.get(position).getTrainer_name());
    holder.area.setText("Area: " + kelasList.get(position).getArea());
    holder.facility.setText("Facility: " + kelasList.get(position).getFacility());
    return v;

}

我认为你根本不应该使用setOnItemClickListener。这是用于单击ListView中的整个项目。

您应该为4个textviews创建4个OnClickListener,并在适配器的getView()中,使用setOnClickListener将4个textviews链接到那些OnClickListeners。

通常你应该将项目位置设置为每个textview的标记,因此在OnClickListener中你可以知道它被view.getTag()

点击的项目。

示例:

public class MyAdapter extends BaseAdapter {
    private MyActivity mActivity

    public MyAdapter(MyActivity activity) {
        mActivity = activity;
    }

    View.OnClickListener listener1 = new View.OnClickListener() {
        @Override
        public void onClick(View v) {
            int position = (int)v.getTag();
            // do stuff based on position or kelasList.get(position)
            // you can call mActivity.startActivity() if you need
        }
    };
    // similar for listener2,3,4

    @Override
    public View getView(int position, View convertView, ViewGroup parent) {
        // convert view = design
        View v = convertView;
        if (v == null) {
            holder = new ViewHolder();
            v = vi.inflate(Resource, null);
            holder.image_carikelas = (ImageView) v.findViewById(R.id.image_carikelas);
            holder.masterclass_name = (TextView) v.findViewById(R.id.masterclass_name);
            holder.studio_nama = (TextView) v.findViewById(R.id.studio_nama);
            holder.trainer_name = (TextView) v.findViewById(R.id.trainer_name);
            holder.area = (TextView) v.findViewById(R.id.area);
            holder.facility = (TextView) v.findViewById(R.id.facility);

            // set OnClickListeners
            holder.studio_nama.setOnClickListener(listener1);
            holder.trainer_name.setOnClickListener(listener2);
            holder.area.setOnClickListener(listener3);
            holder.facility.setOnClickListener(listener4);
            v.setTag(holder);
        } else {
            holder = (ViewHolder) v.getTag();
        }
        //holder.imageview.setImageResource(R.drawable.promo_1);
        new DownloadImageTask(holder.image_carikelas).execute(kelasList.get(position).getImage());
        holder.masterclass_name.setText(kelasList.get(position).getName());
        holder.studio_nama.setText(kelasList.get(position).getStudio_nama());
        holder.trainer_name.setText("Trainer: " + kelasList.get(position).getTrainer_name());
        holder.area.setText("Area: " + kelasList.get(position).getArea());
        holder.facility.setText("Facility: " + kelasList.get(position).getFacility());

        // set tags
        holder.studio_nama.setTag(position);
        holder.trainer_name.setTag(position);
        holder.area.setTag(position);
        holder.facility.setTag(position);
        return v;

    }
}
