Question

我通过为每一行（Contact）扩展LinearLayout创建了一个自定义ListView，我需要选择项目，但方法＆＃34; setOnItemClickListener（）＆＃34;不工作我刚刚放了一个onItemSelectedListener，现在是方法＆＃34; setOnItemClickListener＆＃34;尽管我选择了其他行

，但总是选择第一项

MainActivity：

public class PhoneBookAdapter extends BaseAdapter{

private Context mContext;
private List<PhoneBook> mListPhoneBook;

public PhoneBookAdapter (Context context, List<PhoneBook> list) {
    mContext = context;
    mListPhoneBook = list;
}
@Override
public int getCount() {
    return mListPhoneBook.size();
}
@Override
public Object getItem(int position) {
    return mListPhoneBook.get(position);
}
@Override
public long getItemId(int position) {
    return position;
}

@Override
public View getView(int position, View convertView, ViewGroup parent) {
    PhoneBook entry = mListPhoneBook.get(position);

    if (convertView == null) {
        LayoutInflater inflater = LayoutInflater.from(mContext);
        convertView = inflater.inflate(R.layout.phonebook_row,null);
    }

    ImageView ivAvatar = (ImageView)convertView.findViewById(R.id.imgAvatar);
    ivAvatar.setImageBitmap(entry.getmAvatar());

    TextView tvName = (TextView)convertView.findViewById(R.id.tvName);
    tvName.setText(entry.getmName());

    TextView tvPhone = (TextView)convertView.findViewById(R.id.tvPhone);
    tvPhone.setText(entry.getmPhone());

    TextView tvEmail = (TextView)convertView.findViewById(R.id.tvEmail);
    tvEmail.setText(entry.getmEmail());

    TextView tvID = (TextView)convertView.findViewById(R.id.tvID);
    tvID.setText(entry.getmID());

    return convertView;
}

 }

PhoneBookAdapter：

 <?xml version="1.0" encoding="utf-8"?>

</LinearLayout>

</LinearLayout>

PhoneBook_row：

[C, h1] = contourf(X, Y, log(Z)); 
clabel(C,h1);

Answer 1

将PhoneBook_row.xml替换为我在这里放置的android:clickable="true"，我已经尝试了这个并且它对我有用。我已将您的所有android:clickable="false"更改为ListView。这样做的原因是，您的所有子视图都使用了click，结果是您的父视图，即<?xml version="1.0" encoding="utf-8"?> <LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" android:orientation="horizontal" android:layout_width="match_parent" android:layout_height="match_parent" android:clickable="false"> <ImageView android:id="@+id/imgAvatar" android:layout_width="70dp" android:layout_height="70dp" android:scaleType="fitCenter" android:src="@drawable/image" android:clickable="false"/> <LinearLayout android:layout_width="match_parent" android:layout_height="wrap_content" android:orientation="vertical" android:clickable="false"> <TextView android:layout_width="match_parent" android:layout_height="wrap_content" android:id="@+id/tvName" android:textStyle="bold" android:clickable="false"/> <TextView android:layout_width="match_parent" android:layout_height="wrap_content" android:id="@+id/tvPhone" android:textStyle="bold" android:clickable="false"/> <TextView android:layout_width="match_parent" android:layout_height="wrap_content" android:id="@+id/tvEmail" android:textStyle="bold" android:clickable="false"/> <TextView android:layout_width="match_parent" android:layout_height="wrap_content" android:id="@+id/tvID" android:textStyle="bold" android:clickable="false"/> </LinearLayout> </LinearLayout>没有获得click事件。希望这会有所帮助。

Answer 2

看起来你错过了覆盖。在函数前添加 @Override ，如下所示。

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


            }
        });

在布局文件中添加android：clickable = true也不是必需的。

Answer 3

你已经改变了你的问题，无论如何我相信你现在可以让所选择的项目听众工作了。要获取所选项目，您可以使用以下位置

     lvPhone.setOnItemClickListener(new AdapterView.OnItemClickListener() {

            @Override
            public void onItemClick(AdapterView<?> parent, View view, int position, long id) {

                PhoneBook phoneBook = listPhoneBook.get(position);                 
                Toast.makeText(MainActivity.this, phoneBook.getName() , Toast.LENGTH_SHORT).show(); 
//where getName is a function to get the name in the phonebook class
            }
        });

setOnItemClickListener（）不在ListView上工作（总是选择第一行）
