[gagan50]

Please let us know how i can get selected value and scoll list on click to next item and code below of CircularViewRTLMode.

@Override public void applyToView(View v, RecyclerView parent) { float halfHeight = v.getHeight() 0.5f; float parentHalfHeight = parent.getHeight() 0.5f; float y = v.getY(); float rot = parentHalfHeight - halfHeight - y; Log.e("paent", "applyToView:>>"+parent.getChildAdapterPosition(v) ); ViewCompat.setPivotX(v, v.getWidth()); ViewCompat.setPivotY(v, halfHeight); ViewCompat.setRotation(v, -1 rot 0.05f); ViewCompat.setTranslationX(v, -1 (float) (-Math.cos(rot mTranslationRatio mDegToRad) + 1) mCircleOffset);

    float scale = 1.0f - Math.abs(parentHalfHeight - halfHeight - y) * mScalingRatio;
    ViewCompat.setScaleX(v, scale);
    ViewCompat.setScaleY(v, scale);
}

in branch #12 add CurrentItemCallback in class CircleRecyclerView, in CircularViewRTLMode can't get selected value and scoll list on click to next item, you can add setCurrentItemCallback, get the center selected value, and if you want get other item value when click, you can add itemView.setOnClickListener(yourListener) in onBindViewHolder, and CurrentItemCallback#onItemInCenter will also called

notice

this branch not merge to master, you can watch the sample Issue12Activity.java and CircleRecyclerView.java in branch #12

and if you want other item support click, do not add setOnCenterItemClickListener

[gagan50]

is there anyway to get value that has been set after scroll the wheel in circularRTL becuase i'am using that one

[kHRYSTAL]

@gagan50 this commit is the code how to get select value

pls watch the branch

[gagan50]

is there any way to get selected value in curcularViewRTLMode?

[kHRYSTAL]

@gagan50 get selected value not dependence the child class of ItemViewMode, and I write the CurrentItemCallback is in the CircleRecyclerView, it's adapted all of ItemViewMode

[gagan50]

i have an arraylist

ArrayList arrayList = new ArrayList<>(); arrayList.add(0, "Mandarian"); arrayList.add(1, "Spanish"); arrayList.add(2, "English"); arrayList.add(3, "Arabic"); arrayList.add(4, "Portuguese"); arrayList.add(5, "Russian"); arrayList.add(6, "Thai ");

mCircleRecyclerView.setCurrentItemCallback(new CurrentItemCallback() {

@Override
public void onItemInCenter(View centerItem) {
    Log.e("onItemInCenter", "onItemInCenter:>>center" );

    int position = (int) centerItem.getTag(R.string.item_position);

    position = position % arrayList.size();
    Log.e("LENGTH_SHORT", "onItemInCenter:>>>>>>>"+position);

}

});

while run it's crash java.lang.NullPointerException: Attempt to invoke virtual method 'int java.lang.Integer.intValue()' on a null object reference

[kHRYSTAL]

pls watch my whole commit you need holder.itemView.setTag(R.string.item_position, position); in onBindViewHolder at first

[gagan50]

Hello sir/ma'm

Thank you so much for such patience and guideline. Successfully its working

[gagan50]

may i know that how i can start scroll list from first position

[kHRYSTAL]

@gagan50 in current version not support scroll from first position, because, it's conflict with findViewAtCenter

but you can write like this after recyclerView.setAdapter()

mCircleRecyclerView.post(new Runnable() {
            @Override
            public void run() {
                mCircleRecyclerView.scrollBy(0, -mCircleRecyclerView.getHeight()/2 + mCircleRecyclerView.getChildAt(0).getHeight()/2);
            }
        });

and this is a hack method

[gagan50]

i have write after set adapter it's send exception i.e

java.lang.NullPointerException: Attempt to invoke virtual method 'int

android.view.View.getHeight()' on a null object reference

[kHRYSTAL]

you need must ensure the adapter have datas, and you have to use mCircleRecyclerView.post() to ensure the itemView is display on screen before execute mCircleRecyclerView.scrollBy, also, if you know the itemView height, you can write the fixed value to replace mCircleRecyclerView.getChildAt(0).getHeight()

[gagan50]

I have implemented below code please review

ArrayList arrayList=new ArrayList<>(); arrayList.add(0, "Mandarian"); arrayList.add(1, "Spanish"); arrayList.add(2, "English"); arrayList.add(3, "Arabic"); arrayList.add(4, "Portuguese"); arrayList.add(5, "Russian"); arrayList.add(6, "Thai ");

    mCircleRecyclerView.setAdapter(new A(arrayList));

    mCircleRecyclerView.post(new Runnable() {
        @Override
        public void run() {
            mCircleRecyclerView.scrollBy(0,

-mCircleRecyclerView.getHeight()/2 + mCircleRecyclerView.getChildAt(0).getHeight()/2); } });

[kHRYSTAL]

@gagan50 yes i thought it works

[gagan50]

but sir it through exception

[kHRYSTAL]

you can test your code in my sample menu item NOLOOPBUTCENTER, i test it works

[gagan50]

ok let me know that how i can change color of selected item
