click delay

addDisposable(RxView.clicks(view)
     .throttleFirst(BTN_THROTTLE_DELAY_TIME, TimeUnit.MILLISECONDS)
     .subscribe(v -> handlerClicked()) );

以上大概意思：重复依赖，重复了条目。

1、清除一下缓存：File->Invalidate Caches/Restart..

注意：
除开Gradle依赖类库之外，还可以在项目中的libs下静态方式添加类库。
若是使用静态方式添加jar类库的，请删除重复的jar。

2、编译前clean下

build.gradle中没有buildToolsVersion,配置一下就好了

却换NDK版本，我用了android-ndk-r15b

ndk {
    // abiFilters 'armeabi' //, 'x86', 'armeabi-v7a', 'x86_64', 'arm64-v8a'
    abiFilters 'armeabi-v7a', "armeabi"
}

Transformation<Bitmap> circleCrop = new CircleCrop();
if (data.imgUrl.endsWith("gif")) {
    Glide.with(context)
            .asGif()
            .diskCacheStrategy(DiskCacheStrategy.NONE)
            .load(data.imgUrl)
            .into(imageView);
} else if (data.imgUrl.endsWith("webp")) {
    Glide.with(context)
            .load(data.imgUrl)
            .optionalTransform(circleCrop)
            .optionalTransform(WebpDrawable.class, new WebpDrawableTransformation(circleCrop))
            .into(imageView);
} else {
    Glide.with(context)
            .load(data.imgUrl)
            .into(imageView);
}

因为在Activity设置了主题背景，导致没有设置背景的TextView默认带有了一个背景图片
