ViewPump ======== View inflation you can intercept. ViewPump installs a custom `LayoutInflater` via a `ContextThemeWrapper` and provides an API of pre/post-inflation interceptors. ## Getting started ### Dependency Include the dependency [Download (.aar)](http://search.maven.org/remotecontent?filepath=io/github/inflationx/viewpump/2.1.0/viewpump-2.1.0.aar) : ```groovy dependencies { implementation 'io.github.inflationx:viewpump:2.1.0' } ``` ### Usage Define your interceptor. Below is a somewhat arbitrary example of a post-inflation interceptor that prefixes the text in a TextView. ```java public class TextUpdatingInterceptor implements Interceptor { @Override public InflateResult intercept(Chain chain) { InflateResult result = chain.proceed(chain.request()); if (result.view() instanceof TextView) { // Do something to result.view() // You have access to result.context() and result.attrs() TextView textView = (TextView) result.view(); textView.setText("[Prefix] " + textView.getText()); } return result; } } ``` Below is an example of a pre-inflation interceptor that returns a CustomTextView when a TextView was defined in the layout's XML. ```java public class CustomTextViewInterceptor implements Interceptor { @Override public InflateResult intercept(Chain chain) { InflateRequest request = chain.request(); if (request.name().endsWith("TextView")) { CustomTextView view = new CustomTextView(request.context(), request.attrs()); return InflateResult.builder() .view(view) .name(view.getClass().getName()) .context(request.context()) .attrs(request.attrs()) .build(); } else { return chain.proceed(request); } } } ``` ## Installation Create a `ViewPump` instance via `ViewPump.builder()` and add your interceptors. The order of the interceptors is important since they form the interceptor chain of requests and results. An interceptor may choose to return a programmatically instantiated view rather than letting the default inflation occur, in which case interceptors added after it will be skipped. For this reason, it is better to add your post-inflation interceptors before the pre-inflation interceptors ```java ViewPump viewPump = ViewPump.builder() .addInterceptor(new TextUpdatingInterceptor()) .addInterceptor(new CustomTextViewInterceptor()) .build() ``` Once the instance is created (via dependency injection or otherwise), provide it to your relevant context via wrapping the `Activity` context: ```java @Override protected void attachBaseContext(Context newBase) { super.attachBaseContext(ViewPumpContextWrapper.wrap(newBase, viewPump)); } ``` _You're good to go!_ To see more ideas for potential use cases, check out the [Recipes](https://github.com/InflationX/ViewPump/wiki/Recipes) wiki page. ## Testing If you need to test views in isolation (i.e. not under the indirect umbrella of an `Activity`), you need to set `factory2` manually in order for `ViewPump` to work. ```kotlin val context = ViewPumpContextWrapper.wrap(textContext, viewPump) LayoutInflater.from(context).factory2 = FakeFactory2() // Can be a stub that just returns null // Now inflate your view val view = LayoutInflater.from(context).inflate(R.layout.view, null) ``` Otherwise, no `factory2` instance will be set in the underlying `LayoutInflater` and subsequently `ViewPump` will never be called during inflation. ## Collaborators - [@jbarr21](https://github.com/jbarr21) - [@chrisjenx](https://github.com/chrisjenx) ## Licence Copyright 2017 InflationX Licensed under the Apache License, Version 2.0 (the "License"); you may not use this file except in compliance with the License.
