Android的上拉，以刷新与ListView的片段放;自定义的ListView适配器 [英] Android Pull-to-Refresh with ListView Fragment & Custom ListView Adapter

问题描述

我采用的是Android Studio的启动选项构建我的项目（​​自动生成的操作栏的标签），所以对我产生了一点。然而，我却实现对标签中的每一个列表视图片段使用自定义适配器。

I built my project using the Android Studio start options (Automatically builds the action bar with the tabs) so a bit is generated for me. I did however implement a list-view fragment for each one of the tabs that uses custom adapters.

我有一个麻烦来自克里斯贝恩。也许我输入错了？我是相当新的android开发，特别是与这种新的摇篮东西。

I'm having a trouble adding the pull-to-refresh lib from Chris Bane. Maybe I'm importing it wrong? I'm fairly new at android development and especially with this new Gradle stuff.

我导入GitHub的信息库中的build.gradle文件位置：

I'm Importing the github repository in the build.gradle file here:

apply plugin: 'android'

android {
compileSdkVersion 19
buildToolsVersion "19.0.1"

defaultConfig {
    minSdkVersion 14
    targetSdkVersion 19
    versionCode 1
    versionName "1.0"
}
buildTypes {
    release {
        runProguard false
        proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.txt'
    }
  }
}
dependencies {
   compile 'com.android.support:support-v4:19.0.1'
   compile 'com.android.support:appcompat-v7:19.0.1'
   compile 'com.github.chrisbanes.actionbarpulltorefresh:extra-abc:+'
 } 

一切都减去的minSdkVersion＆放大器;在依赖过去的编译是pre-生成我的项目创建时。这的build.gradle文件是一个在我的`/ app文件夹。

Everything minus the minSDKVersion & the last compile in dependencies was pre-generated when my project was created. This build.gradle file is the one in my `/app folder.

摇篮会正常同步，我会在项目的根看到我.idea文件夹从动作条git的文件。

Gradle will sync properly and I will see files from the actionbar git in my .idea folder in the project root.

这里是我越来越糊涂：

在GitHub的回购快速启动它说。

In the github repo "quick start" it says

您需要做的是包装你的看法刷新在PullToRefreshLayout的第一件事情：

The first thing you need to do is wrap your refreshable view in a PullToRefreshLayout:

随着code例如做这样的事情：

With a code example doing something like this:

<uk.co.senab.actionbarpulltorefresh.extras.actionbarcompat.PullToRefreshLayout>
<listview/>
</uk.co.senab.actionbarpulltorefresh.extras.actionbarcompat.PullToRefreshLayout>

为 uk.co.senab.actionbarpulltorefresh.extras 假设是我的项目的名字，所以 com.lucaapp.app <​​/ code>

Is uk.co.senab.actionbarpulltorefresh.extras suppose to be my projects name, so com.lucaapp.app?

下面是我的XML我ListFragment，日子会把你在哪里看到我的困惑：

Here is my XML for my ListFragment, where u'll see my confusion:

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

<com.lucaapp.app.PullToRefreshLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="vertical"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:id="@+id/ptr_layout" >


<ListView
    android:id="@android:id/list"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:divider="#b5b5b5"
    android:dividerHeight="1dp"
    android:listSelector="@drawable/list_selector" />


<TextView
    android:id="@android:id/empty"
    android:layout_width="fill_parent"
    android:layout_height="fill_parent"
    android:text="No Events" />

</com.lucaapp.app.PullToRefreshLayout>

这不会立即给我任何错误，直到我试图实现从快速入门指南在我的片段类code。我得到一个无法解析符号错误尝试导入的github回购的方法。

This will not give me any errors immediately until I try to implement the code from the quick start guide in my fragment class. I get an Cannot Resolve Symbol error trying to import that github repo methods.

我已经试过这使得进口红色无法解析符号以下错误：

I've tried the following which makes the import red with cannot resolve symbol error:

import com.lucapp.app.PullToRefreshAttacher;
import com.lucapp.app.PullToRefreshLayout;
import uk.co.senab.actionbarpulltorefresh.extras.actionbarcompat.PullToRefreshAttacher;

我认为我有问题的只是我缺少进口图书馆的知识（从来没有这样做），所以请与我裸露，如果这是一个明显的修复。希望我提供足够的信息来帮助解决这个问题。

I assume the issues I'm having is just me lacking the knowledge of importing libraries (Never done it before) so please bare with me if this is an obvious fix. Hope I provided enough information to help resolve this.

推荐答案

你试过跟随克里斯巴内斯本教程：
https://github.com/chrisbanes/ActionBar-PullToRefresh/wiki/QuickStart-ABS
？

Have you tried to follow this tutorial from Chris Banes: https://github.com/chrisbanes/ActionBar-PullToRefresh/wiki/QuickStart-ABS ?

本教程包含所有步骤，从开始的build.gradle和code段完成。

This tutorial contains all steps, beginning from build.gradle and finishing with code snippets.

唯一的区别：教程是滚动型（不ListView控件如你所愿）。但是，不要害怕。只是替代的ListView滚动型，一切都应该确定。

The only difference: tutorial is for ScrollView (not ListView as you wish). But don't be scared. Just replace ScrollView with ListView and everything should be OK.

更新：

<uk.co.senab.actionbarpulltorefresh.extras.actionbarsherlock.PullToRefreshLayout
    xmlns:android="http://schemas.android.com/apk/res/android"
    android:id="@+id/ptr_layout"
    android:layout_width="match_parent"
    android:layout_height="match_parent">

    <!-- Your content, here we're using a ScrollView -->

    <ScrollView
        android:layout_width="match_parent"
        android:layout_height="match_parent">

    </ScrollView>

</uk.co.senab.actionbarpulltorefresh.extras.actionbarsherlock.PullToRefreshLayout>

你不应该使用 com.lucaapp.app.PullToRefreshLayout 而不是 uk.co.senab.actionbarpulltorefresh.extras.actionbarsherlock.PullToRefreshLayout
