StateView

中文

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:

   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.

    mStateView = StateView.inject(Activity activity);

    mStateView = StateView.inject(ViewGroup parent);

    mStateView = StateView.inject(ViewGroup parent, boolean hasActionBar);

    // if view is not ViewGroup, StateView will be inject to view.getPatent()
    mStateView = StateView.inject(View view);

    mStateView = StateView.inject(View view, boolean hasActionBar);

    mStateView = StateView.wrap(View view);

Or include the StateView widget in your layout.

    <com.github.nukc.stateview.StateView
        android:id="@+id/stateView"
        android:layout_width="match_parent"
        android:layout_height="match_parent"/>

To switch the state view:

• mStateView.showEmpty();
• mStateView.showLoading();
• mStateView.showRetry();
• mStateView.showContent();

To listen the retry click:

    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.

setEmptyResource(@LayoutRes int emptyResource)

setRetryResource(@LayoutRes int retryResource)

setLoadingResource(@LayoutRes int loadingResource)

use setOnInflateListener to set message, like AnimatorActivity.java#L28

Custom Attribute

<resources>
    <declare-styleable name="StateView">
        <attr name="emptyResource" format="reference" />
        <attr name="retryResource" format="reference" />
        <attr name="loadingResource" format="reference" />
    </declare-styleable>
</resources>

Animation

set:

    // provider default is null, no animation
    // if need, set a AnimatorProvider
    setAnimatorProvider(AnimatorProvider provider)

animation can custom, can also compile animations

    compile 'com.github.nukc.stateview:animations:1.0.1'

animations library has:

• FadeScaleAnimatorProvider
• FlipAnimatorProvider
• SlideAnimatorProvider

if want a custom animation，implements AnimatorProvider

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;
    }
}
