Custom Contents Loading Progress (컨텐츠 로딩 프로그레스)

무엇인가 로딩을 할때 띄워줄 로딩 프로그레스이다.

 

Animation을 사용해 Image를 Rotate 한다.

class ContentsLoadingProgress {
    companion object {
        const val LOADING_SCREEN_TAG = "contents_loading_screen"

        val mContentViewHashMap: HashMap<String, ViewGroup> = HashMap()

        @JvmStatic
        @JvmOverloads
        /**
         * @param touchable = 콘텐츠 로딩화면 뒤에 터치되지 않게 설정
         */
        fun showProgress(key: String, activity: Activity, touchable: Boolean = false) {
            if(mContentViewHashMap.containsKey(key)) return//이미 노출 중이라면.

            val contentView = activity.findViewById<ViewGroup>(android.R.id.content)
            mContentViewHashMap.put(key, contentView)

            val inflater = LayoutInflater.from(activity)
            inflater.inflate(R.layout.include_contents_loading_screen, null)?.let {
                it.isClickable = touchable
                contentView.addView(it)
                it.layoutParams?.apply {
                    width = ViewGroup.LayoutParams.MATCH_PARENT
                    height = ViewGroup.LayoutParams.MATCH_PARENT
                }

                val loadingImageView = it.findViewById<ImageView>(R.id.vodlist_loading_pregross)
                val rotateAnim = AnimationUtils.loadAnimation(activity, R.anim.loading_image_rotate_anim)
                rotateAnim.fillAfter = true
                loadingImageView.animation = rotateAnim

                it.tag = LOADING_SCREEN_TAG
            }
        }

        @JvmStatic
        fun hideProgress(key: String) {
            if(mContentViewHashMap.containsKey(key)) {
                mContentViewHashMap.get(key)?.apply {
                    val loadingScreen: View? = findViewById<View>(R.id.loading_screen)
                    if(loadingScreen != null && loadingScreen.visibility == View.VISIBLE)
                        loadingScreen.visibility = View.GONE
                    removeView(findViewWithTag(LOADING_SCREEN_TAG))
                }
                mContentViewHashMap.remove(key)
            }
        }
    }
}

include_contents_loading_screen.xml

<?xml version="1.0" encoding="utf-8"?>
<FrameLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:id="@+id/loading_screen"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:background="#80000000">

    <ImageView
        android:id="@+id/vodlist_loading_pregross"
        android:layout_width="@dimen/common_90dp"
        android:layout_height="@dimen/common_90dp"
        android:layout_gravity="center"
        android:src="@drawable/loading"/>

</FrameLayout>

 

사용되는 anim

linear_interpolator.xml

<?xml version="1.0" encoding="utf-8"?>
<linearInterpolator xmlns:android="http://schemas.android.com/apk/res/android" />

 

loading_image_rotate_anim.xml

drawable 이미지는 구현의도에 맞게 수정

<?xml version="1.0" encoding="utf-8"?>
<rotate xmlns:android="http://schemas.android.com/apk/res/android"
    android:duration="6000"
    android:fromDegrees="0"
    android:toDegrees="360"
    android:pivotX="50%"
    android:pivotY="50%"
    android:repeatCount="infinite"
    android:interpolator="@anim/linear_interpolator">
</rotate>

 

사용

ContentsLoadingProgress.showProgress(this.getLocalClassName(), this, true) //Progress Show
ContentsLoadingProgress.hideProgress(this.localClassName) //Progress Hide

//ContentsLoadingProgress.showProgress(mActivity.getLocalClassName(), mActivity, true) //Progress Show
//ContentsLoadingProgress.hideProgress(mActivity.localClassName) //Progress Hide
