# PageStateManager/StatefulFrameLayout
页面状态管理
[](https://jitpack.io/#hss01248/PageStateManager)
在张鸿洋的[LoadingAndRetryManager](https://github.com/hongyangAndroid/LoadingAndRetryManager)的基础上改写,修正一些bug,优化api,并提供使用时封装的例子
# 特性
* api超级简单
* 可以在xml中使用StatefulFrameLayout
* 也可以不改动xml,直接在代码里使用PageStateManager
* 错误页面和空白页面均提供了点击事件的回调,直接实现即可
* 不改动framlayout本身任何属性,依然可以添加多个子view
# 更新:fragment的操作改变了
由于fragment的生命周期引起的bug,已取消原先直接传入fragment对象的方式.
请改成传入组成fragment的view,注意该view对象传入时,其parent不能为空,也就是,该view不能是xml的根view,可以自己随便包一层.
ps.
其实fragment本质也是基于view包裹了一层api,搞点生命周期之类的,api难用得要死,还一大堆坑,还不如自己包装一个view,自己加点生命周期,高度可控,减少bug.我的项目中从来都不用fragment,都是自己把view包装成各种page.
# API
> 参考demo里的,自己封装一层(拷过去改一改)
## 接口
```
public interface IViewState {
void showLoading();
void showError(CharSequence msg);
void showContent();
void showEmpty();
}
```
# 四个级别的配置
### 库内默认
自带Loading,Empty,Error的xml:
```
public static int BASE_LOADING_LAYOUT_ID = R.layout.pager_loading;
public static int BASE_RETRY_LAYOUT_ID = R.layout.pager_error;
public static int BASE_EMPTY_LAYOUT_ID = R.layout.pager_empty;
```
## 使用时可全局配置
在application的oncreate里调用:
也就是修改上述的三个静态变量:
```
PageStateManager.initInAppOnCreate():
```
```
public static void initInApp(int layoutIdOfEmpty, int layoutIdOfLoading, int layoutIdOfError) {
if (layoutIdOfEmpty != 0) {
BASE_EMPTY_LAYOUT_ID = layoutIdOfEmpty;
}
if (layoutIdOfLoading != 0) {
BASE_LOADING_LAYOUT_ID = layoutIdOfLoading;
}
if (layoutIdOfError != 0) {
BASE_RETRY_LAYOUT_ID = layoutIdOfError;
}
}
```
## 单个页面的配置:
### 可配置的项目:
// PageConfig为抽象类:
仅一个必须实现的方法:
public abstract class PageConfig {
public abstract void onRetry(View retryView);//必须实现
public void onEmtptyViewClicked(View emptyView) {
onRetry(emptyView);
}
public boolean isFirstStateLoading(){
return true;
}
public String emptyMsg(){
return "";
}
public int customLoadingLayoutId() {
return PageStateManager.BASE_LOADING_LAYOUT_ID;
}
public int customErrorLayoutId() {
return PageStateManager.BASE_RETRY_LAYOUT_ID;
}
public int customEmptyLayoutId() {
return PageStateManager.BASE_EMPTY_LAYOUT_ID;
}
### xml里使用statefulFrameLayout时:
```
```
```
statefulFrameLayout.init(new PageConfig() {
@Override
public void onRetry(View retryView) {
doNet();
}
});
```
### 或者使用PageStateManager:
```
/**
*
* @param container 必须为activity或者view.如果是view,则该view对象必须有parent
*/
pageStateManager = PageStateManager.initWhenUse(container,new MyPageConfig() {
@Override
protected void onReallyRetry() {
doNet();
}
@Override
public int customEmptyLayoutId() {
return R.layout.pager_empty_2;
}
@Override
public int customLoadingLayoutId() {
return R.layout.pager_loading_2;
}
@Override
public int customErrorLayoutId() {
return R.layout.pager_error_2;
}
});
```
## 控制页面状态的api:
```
public void showLoading()
public void showContent()
public void showEmpty()
public void showError(CharSequence errorMsg)
```
# demo中的默认的几个页面状态UI图
其中无网络时弹出dialog:
无网络的对话框可以全局复写:
```
NoNetworkHelper.setShowDialogImpl(IShowDialog showDialog)
public interface IShowDialog{
void showNoNetWorkDlg(final Context context);
}
```
# 使用
## gradle
**Step 1.** Add the JitPack repository to your build file
Add it in your root build.gradle at the end of repositories:
```
allprojects {
repositories {
...
maven { url "https://jitpack.io" }
}
}
```
**Step 2.** Add the dependency
```
dependencies {
compile 'com.github.hss01248:PageStateManager:3.0.1'
}
```
## 示例代码(详见demo)
## xml里不写StatefulFramelayout时:
```
private void initView() {
setContentView(R.layout.activity_main);
pageStateManager = PageStateManager.initWhenUse(this,new PageConfig() {
@Override
public int customEmptyLayoutId() {
return R.layout.pager_empty_2;
}
@Override
public void onRetry(View retryView) {
doNet();
}
@Override
public int customLoadingLayoutId() {
return R.layout.pager_loading_2;
}
@Override
public int customErrorLayoutId() {
return R.layout.pager_error_2;
}
});
}
private void doNet() {
pageStateManager.showLoading();
new Handler().postDelayed(new Runnable() {
@Override
public void run() {
int state = new Random().nextInt(3);
switch (state){
case 0:
pageStateManager.showError("稍候重试");
break;
case 1:
pageStateManager.showEmpty();
break;
case 2:
pageStateManager.showContent();
}
}
},2000);
}
```
## 在xml里直接写时:
```
......
statefulFrameLayout = (StatefulFrameLayout)findViewById(R.id.pager);
statefulFrameLayout.init(new PageConfig() {
@Override
public void onRetry(View retryView) {
doNet();
}
});
doNet();
}
private void doNet() {
statefulFrameLayout.showLoading();
new Handler().postDelayed(new Runnable() {
@Override
public void run() {
int state = new Random().nextInt(3);
switch (state){
case 0:
statefulFrameLayout.showError("稍候重试222222");
break;
case 1:
statefulFrameLayout.showEmpty();
break;
case 2:
statefulFrameLayout.showContent();
}
}
},2000);
}
```
# 注意事项
1.给view对象设置状态时,该对象必须有parent
2.
