仅可单击来自列表视图的 5 个文本视图中的 4 个文本视图 android

Question

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中使用它时，它仍然是单击整个列表视图行而不是单击我想要单击的文本视图。这是实现该答案后的代码：

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);
        }
    }
});

我要单击的文本视图具有 id：masterclass_name、studio_nama、trainer_name、area。还有另一个 textview id，但我不希望可以单击该 id。所以只能点击5个textview中的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 activity class.

我的代码有什么问题（为什么那个答案对我的代码不起作用）？ How/what 是使 4 textview 变为可点击的正确代码吗？

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;

}

我认为您根本不应该使用 setOnItemClickListener。那是为了单击 ListView 中的整个项目。

您应该为 4 个文本视图创建 4 个 OnClickListeners，并在适配器的 getView() 中使用 setOnClickListener 将 4 个文本视图 link 分配给那些 OnClickListeners。

通常你应该将项目位置设置为每个textview的标签，这样在OnClickListener中你可以知道它被点击了哪个项目 view.getTag()

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;

    }
}
