StateView is an invisible, zero-sized View that can be used to lazily inflate loadingView/emptyView/retryView at runtime.

## Installation
add the dependency to your build.gradle:
```groovy
compile 'com.github.nukc.stateview:library:1.5.4'
// animator providers
compile 'com.github.nukc.stateview:animations:1.0.1'
```
##Usage
Can be directly used in java.
```java
mStateView = StateView.inject(Activity activity);
```
```java
mStateView = StateView.inject(ViewGroup parent);
mStateView = StateView.inject(ViewGroup parent, boolean hasActionBar);
```
```java
// if view is not ViewGroup, StateView will be inject to view.getPatent()
mStateView = StateView.inject(View view);
mStateView = StateView.inject(View view, boolean hasActionBar);
```
```java
mStateView = StateView.wrap(View view);
```
Or include the StateView widget in your layout.
```xml
```
To switch the state view:
- ```mStateView.showEmpty();```
- ```mStateView.showLoading();```
- ```mStateView.showRetry();```
- ``` mStateView.showContent();```
To listen the retry click:
```java
mStateView.setOnRetryClickListener(new StateView.OnRetryClickListener() {
@Override
public void onRetryClick() {
//do something, no need to call showLoading()
}
});
```
To customize view:
- Global settings way: create a new layout (layout's name must be ```base_empty```/```base_retry```/```base_loading```).
- Single page setting: create a new layout whit different name, and set resource in java.
```java
setEmptyResource(@LayoutRes int emptyResource)
setRetryResource(@LayoutRes int retryResource)
setLoadingResource(@LayoutRes int loadingResource)
```
use setOnInflateListener to set message, like AnimatorActivity.java#L28
## Custom Attribute
```xml
```
## Animation
set:
```java
// provider default is null, no animation
// if need, set a AnimatorProvider
setAnimatorProvider(AnimatorProvider provider)
```
animation can custom, can also compile ```animations```
```groovy
compile 'com.github.nukc.stateview:animations:1.0.1'
```
```animations``` library has:
- ```FadeScaleAnimatorProvider```
- ```FlipAnimatorProvider```
- ```SlideAnimatorProvider```
if want a custom animation，implements ```AnimatorProvider```
```java
public class FadeScaleAnimatorProvider implements AnimatorProvider {
@Override
public Animator showAnimation(View view) {
AnimatorSet set = new AnimatorSet();
set.playTogether(
ObjectAnimator.ofFloat(view, "alpha", 0f, 1f),
ObjectAnimator.ofFloat(view, "scaleX", 0.1f, 1f),
ObjectAnimator.ofFloat(view, "scaleY", 0.1f, 1f)
);
return set;
}
@Override
public Animator hideAnimation(View view) {
AnimatorSet set = new AnimatorSet();
set.playTogether(
ObjectAnimator.ofFloat(view, "alpha", 1f, 0f),
ObjectAnimator.ofFloat(view, "scaleX", 1f, 0.1f),
ObjectAnimator.ofFloat(view, "scaleY", 1f, 0.1f)
);
return set;
}
}
```
