App公共组件:加载数据Layout,高效开发必备!

项目中经常会遇到几种页面:加载中、无网络、无数据、出错四种情况,传统的方式是通过include相关的布局,逐个分情况设置显示或隐藏,这样繁琐的过程一直是个痛点,于是参考了 Weavey 的封装套路,自己重新写了一套,进行了一些优化和扩展,虽然说原理不会太复杂(继承FrameLayout,XML渲染完成后,加上四个页面,然后按需控制显示哪一层),但若把它分离出来确实是提升开发效率的一个利器。

LoadDataLayout

Usage

  • step 1:

在你项目的build.gradle文件中添加依赖

compile 'com.ganxin.library:loaddatalayout:1.0.1'

  • step 2:

在需要用到的布局中引入相关的Layout:

普通样式:LoadDataLayout

<com.ganxin.library.LoadDataLayout
    android:id="@+id/loadDataLayout"
    xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent"
    android:layout_height="match_parent">

    <TextView
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        android:background="@color/blue"
        android:gravity="center"
        android:text="contentView"
        android:textColor="@color/white"
        android:textSize="20sp"/>

</com.ganxin.library.LoadDataLayout>

仿知乎样式:SwipeLoadDataLayout

<com.ganxin.library.SwipeLoadDataLayout
    android:id="@+id/swipeLoadDataLayout"
    style="@style/common_swipeLoadDataLayout"
    xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent"
    android:layout_height="match_parent">

    <TextView
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        android:background="@color/blue"
        android:gravity="center"
        android:text="contentView"
        android:textColor="@color/white"
        android:textSize="20sp"/>

</com.ganxin.library.SwipeLoadDataLayout>

支持的自定义属性:

loadingText:加载页面显示的文本,可选,仅LoadDataLayout可用

loadingTextSize:加载页面显示的图片,可选,仅LoadDataLayout可用

loadingTextColor:加载页面文本的颜色,可选,仅LoadDataLayout可用

loadingViewLayoutId:自定义加载页面的布局Id,可选,仅LoadDataLayout可用,如果设置了该属性,上面的三个属性失效

emptyText:无数据页面显示的文本,可选

emptyImgId:无数据页面显示的图片,可选

emptyImageVisible:无数据页面图片的可见性,可选,默认为true

errorText:出错页面显示的文本,可选

errorImgId:出错页面显示的图片,可选

errorImageVisible:出错页面图片的可见性,可选,默认为true

noNetWorkText:无网络页面显示的文本,可选

noNetWorkImgId:无网络页面显示的图片,可选

noNetWorkImageVisible:无网络页面图片的可见性,可选,默认为true

allTipTextColor:无数据、无网络、出错三个页面的文本颜色,可选

allTipTextSize:无数据、无网络、出错三个页面的文本字体大小,可选

allPageBackgroundColor:四个页面的背景色,可选

reloadBtnText:重新加载按钮的文本,可选

reloadBtnTextSize:重新加载按钮的文本字体大小,可选

reloadBtnTextColor:重新加载按钮的文本颜色,可选

reloadBtnBackgroundResource:重新加载按钮的背景资源,可选

reloadBtnVisible:重新加载按钮的可见性,可选,默认为true

reloadClickArea:重新加载按钮的点击区域,full代表整个页面,button代表仅button大小区域,默认button

除了在XML设置属性外,支持全局配置,对所有使用的地方起作用,需要在Application中配置,示例:

public class App extends Application {

    @Override
    public void onCreate() {
        super.onCreate();

        LoadDataLayout.getBuilder()
                .setLoadingText(getString(R.string.custom_loading_text))
                .setLoadingTextSize(16)
                .setLoadingTextColor(R.color.colorPrimary)
                //.setLoadingViewLayoutId(R.layout.custom_loading_view) //如果设置了自定义loading视图,上面三个方法失效
                .setEmptyImgId(R.drawable.ic_empty)
                .setErrorImgId(R.drawable.ic_error)
                .setNoNetWorkImgId(R.drawable.ic_no_network)
                .setEmptyImageVisible(true)
                .setErrorImageVisible(true)
                .setNoNetWorkImageVisible(true)
                .setEmptyText(getString(R.string.custom_empty_text))
                .setErrorText(getString(R.string.custom_error_text))
                .setNoNetWorkText(getString(R.string.custom_nonetwork_text))
                .setAllTipTextSize(16)
                .setAllTipTextColor(R.color.text_color_child)
                .setAllPageBackgroundColor(R.color.pageBackground)
                .setReloadBtnText(getString(R.string.custom_reloadBtn_text))
                .setReloadBtnTextSize(16)
                .setReloadBtnTextColor(R.color.colorPrimary)
                .setReloadBtnBackgroundResource(R.drawable.selector_btn_normal)
                .setReloadBtnVisible(true)
                .setReloadClickArea(LoadDataLayout.FULL);
    }
}

为了适应某个界面的“特殊需求”,也支持局部设置各种属性,仅对当前对象生效,不影响全局,示例:

        loadDataLayout.setEmptyText("暂无数据显示")
                .setErrorText("出错啦")
                .setErrorImage(R.drawable.ic_error)
                .setAllTipTextSize(20)
                .setReloadBtnText("点我重新加载")
                .setReloadClickArea(LoadDataLayout.FULL);
                //and so on...
  • step 3:

为ReloadButton设置监听:

       loadDataLayout.setOnReloadListener(new LoadDataLayout.OnReloadListener() {
            @Override
            public void onReload(View v, int status) {

            }
        });

根据实际需要,设置显示的页面:

        loadDataLayout.setStatus(LoadDataLayout.LOADING); //加载中
        loadDataLayout.setStatus(LoadDataLayout.EMPTY); //无数据
        loadDataLayout.setStatus(LoadDataLayout.ERROR); //出错
        loadDataLayout.setStatus(LoadDataLayout.NO_NETWORK); //无网络
        loadDataLayout.setStatus(LoadDataLayout.SUCCESS); //加载成功

Remarks

  • LoadDataLayout默认一开始是隐藏contengView的,而SwipeLoadDataLayout中设置status为Loading时,contentView是显示的。
  • LoadDataLayout和SwipeLoadDataLayout只能有一个直属子View,类似ScrollView,添加两个直属子View会抛异常:throw new IllegalStateException
