Question

我有一个名为activity_login_user_entity.xml的自定义布局

<ListView
    android:id="@+id/activity_login_user_entity_users"
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:background="@color/white"
    android:clickable="true"
    android:divider="#FFECECEC"
    android:dividerHeight="1dp"
    android:focusable="true" />

和XML适配器：

<ImageButton
    android:id="@+id/adapter_user_login"
    android:layout_width="wrap_content"
    android:layout_height="match_parent"
    android:background="@null"
    android:paddingLeft="15dp"
    android:paddingStart="15dp"
    android:src="@drawable/ic_login" />


<com.neopixl.pixlui.components.textview.TextView
    android:id="@+id/adapter_user_entity"
    style="@style/BoldFont"
    android:layout_width="0dp"
    android:layout_height="match_parent"
    android:layout_weight="1"
    android:gravity="start|center"
    android:padding="20dp"
    android:text="15/05/2015"
    android:textColor="@color/colorBaseApp"
    android:textSize="14sp" />

我的适配器类：

    public class UserAdapter extends BaseAdapter {

    private ArrayList<User> dataList;
    private final LayoutInflater mInflater;
    private final Context mainActivity;

    public UserAdapter(Context context, ArrayList<User> results) {
        super();
        this.dataList = results;
        this.mainActivity = context;
        this.mInflater = LayoutInflater.from(context);
    }

    @Override
    public int getCount() {
        // TODO Auto-generated method stub
        return dataList.size();
    }

    @Override
    public Object getItem(int arg0) {
        // TODO Auto-generated method stub
        return dataList.get(arg0);
    }

    @Override
    public long getItemId(int arg0) {
        // TODO Auto-generated method stub
        return arg0;
    }

    public View getView(int position, View convertView, ViewGroup parent) {
        // TODO Auto-generated method stub

        ViewHolder holder;
        if (convertView == null) {
            convertView = mInflater.inflate(R.layout.adapter_user, null);
            holder = new ViewHolder();
            holder.entity = (TextView) convertView.findViewById(R.id.adapter_user_entity);

            convertView.setTag(holder);
        } else {
            holder = (ViewHolder) convertView.getTag();
        }
        holder.entity.setText(dataList.get(position).getParticipantEntityName());

        return convertView;
    }

    static class ViewHolder {
        TextView entity;
    }

    @Override
    public boolean isEnabled(int position) {
        return true;
    }
}

对话：

final Dialog new_dialog = new Dialog(LoginActivity.this);
        new_dialog.requestWindowFeature(Window.FEATURE_NO_TITLE);
        new_dialog.setContentView(R.layout.activity_login_user_entity);
        new_dialog.setCancelable(false);

        ListView lv = (ListView) new_dialog.findViewById(R.id.activity_login_user_entity_users);

        UserAdapter cdaa = new UserAdapter(getApplicationContext(), users);

        lv.setAdapter(cdaa);

        new_dialog.show();

        lv.setOnItemClickListener(new AdapterView.OnItemClickListener() {

            @Override
            public void onItemClick(AdapterView<?> parent, View view, int position, long id) {
                Toast.makeText(LoginActivity.this, "Item Selected: " + position, Toast.LENGTH_SHORT).show();
            }
        });

我的问题是，所有内容都显示得很好，项目按照我希望的方式存在，但是无法检测到列表视图的项目被点击。有人可以帮帮我吗？

编辑：

我设法使用以下代码：

final ArrayAdapter<User> adapter = new ArrayAdapter<>(this, android.R.layout.select_dialog_item);
        adapter.addAll(users);
        AlertDialog.Builder builder = new AlertDialog.Builder(this);
        builder.setAdapter(adapter, new DialogInterface.OnClickListener() {
            public void onClick(DialogInterface dialog, int item) {
                loginSuccess(adapter.getItem(item));
            }
        });

        AlertDialog alert = builder.create();
        alert.show();

但是，我无法获得我想要的自定义布局。

使用and WeekDate not like '2015-12-27'设置内容

LayoutInflater将布局XML文件实例化为其对应的查看对象。

LayoutInflater

Answer 2

您必须使用LayoutInflater来扩展contentView。列表视图应该从contentView引用，而不是从对话框对象引用。

代码将更改为

    //Inflate the content view
    LayoutInflater layoutInflater = (LayoutInflater) context.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
    View contentView = layoutInflater.inflate(R.layout. activity_login_user_entity, null, false);

    //ListView related activities
    ListView lv = (ListView) contentView.findViewById(R.id.activity_login_user_entity_users);
    UserAdapter cdaa = new UserAdapter(getApplicationContext(), users);
    lv.setAdapter(cdaa);
    lv.setOnItemClickListener(new AdapterView.OnItemClickListener() {

        @Override
        public void onItemClick(AdapterView<?> parent, View view, int position, long id) {
            Toast.makeText(LoginActivity.this, "Item Selected: " + position, Toast.LENGTH_SHORT).show();
        }
    });


    //Dialog creation
    final Dialog new_dialog = new Dialog(LoginActivity.this);
    new_dialog.requestWindowFeature(Window.FEATURE_NO_TITLE);
    new_dialog.setContentView(contentView); 
    new_dialog.setCancelable(false);       

    //Dialog display
    new_dialog.show();

您需要停用 ImageButton 焦点。将此属性添加到XML布局文件中的 ImageButton 。

android:focusable="false"
android:focusableInTouchMode="false"

当listview位于Dialog中时，OnItemClickListeneris不会触发
