Recycler + Switch Button

Recycler + Switch Button

1. 라이브러리 추가

Project Structure > app > Dependencies > + > Library Dependency > recyclerview 추가

2. 레이아웃 구성

activity_recycler_switch.xml

<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:tools="http://schemas.android.com/tools"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    tools:context="com.pje.android.recyclerviewsample.SwitchRecyclerActivity">
    <android.support.v7.widget.RecyclerView
        android:id="@+id/recycler"
        android:layout_width="match_parent"
        android:layout_height="match_parent"/>
</RelativeLayout>
 
 

row_switch.xml

 
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:orientation="vertical"
    android:layout_width="match_parent"
    android:layout_height="match_parent">
    <TextView
        android:id="@+id/textTitle"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:padding="@dimen/row_textView_padding"
        android:text="test"/>
    <android.support.v7.widget.SwitchCompat
        android:id="@+id/switchOnOff"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_marginRight="20dp"
        android:layout_alignParentRight="true"/>
 
 
</RelativeLayout>

3. Adapter 생성

SwitchRecyclerAdapter.java

 
public class SwitchRecyclerAdapter extends RecyclerView.Adapter<SwitchRecyclerAdapter.ViewHolder> {
 
    private Context mContext = null;
    private List<SwitchItemVO> mDataList = null;
 
    private OnItemClickedListener mItemClickListener = null;
    private OnCheckedChangeListener onItemCheckedListener;
 
    public interface OnItemClickedListener {
        void onItemClicked(SwitchItemVO vo, int position);
    }
 
    public interface OnCheckedChangeListener {
        void onCheckedChanged(int position , boolean isChecked);
    }
 
    public SwitchRecyclerAdapter(Context context, List<SwitchItemVO> items) {
        mContext = context;
        mDataList = items;
    }
 
    public void setOnClickListener(OnItemClickedListener listener) {
        mItemClickListener = listener;
    }
 
    public void setOnCheckedChangeListener(OnCheckedChangeListener listener) {
        onItemCheckedListener = listener;
    }
 
    @Override
    public ViewHolder onCreateViewHolder(ViewGroup parent, int viewType) {
        View v = LayoutInflater.from(parent.getContext()).inflate(R.layout.row_switch, parent, false);
        return new ViewHolder(v);
    }
 
    @Override
    public void onBindViewHolder(ViewHolder holder, int position) {
        SwitchItemVO item = mDataList.get(position);
 
        holder.title.setText(item.getTitle());
        if (item.isSwitch()) {
            holder.switchBtn.setVisibility(View.VISIBLE);
        } else {
            holder.switchBtn.setVisibility(View.GONE);
        }
        holder.switchBtn.setTag(position);
        holder.switchBtn.setOnCheckedChangeListener(mOnCheckedChangeListener);
 
        holder.itemView.setTag(position);
        holder.itemView.setOnClickListener(mOnClickListener);
    }
 
    @Override
    public int getItemCount() {
        return mDataList.size();
    }
 
    public class ViewHolder extends RecyclerView.ViewHolder {
        TextView title;
        SwitchCompat switchBtn;
 
        public ViewHolder(View itemView) {
            super(itemView);
            title = (TextView) itemView.findViewById(R.id.textTitle);
            switchBtn = (SwitchCompat) itemView.findViewById(R.id.switchOnOff);
        }
    }
 
    /**
     * 클릭 리스너
     */
    private View.OnClickListener mOnClickListener = new View.OnClickListener() {
        @Override
        public void onClick(View v) {
            int position = (int) v.getTag();
 
            if (mItemClickListener != null) {
                mItemClickListener.onItemClicked(mDataList.get(position), position);
            }
        }
    };
 
    /**
     * 스위치 리스너
     */
    private CompoundButton.OnCheckedChangeListener mOnCheckedChangeListener = new CompoundButton.OnCheckedChangeListener() {
        @Override
        public void onCheckedChanged(CompoundButton buttonView, boolean isChecked) {
            int position = (int) buttonView.getTag();
 
            if (onItemCheckedListener != null) {
                onItemCheckedListener.onCheckedChanged(position, isChecked);
            }
        }
    };
}
 
 

4. VO

SwitchItemVO.java

 
public class SwitchItemVO {
    private String title;
    private boolean isSwitch;
 
    public SwitchItemVO(String title, boolean isSwitch) {
        this.title = title;
        this.isSwitch = isSwitch;
    }
 
    public String getTitle() {
        return title;
    }
 
    public void setTitle(String title) {
        this.title = title;
    }
 
    public boolean isSwitch() {
        return isSwitch;
    }
 
    public void setIsSwitch(boolean isSwitch) {
        this.isSwitch = isSwitch;
    }
}

5. Activity

SwitchRecyclerActivity.java

 
public class SwitchRecyclerActivity extends Activity {
 
    private RecyclerView recyclerView = null;
    private LinearLayoutManager layoutMgr = null;
 
    private List<SwitchItemVO> mDataList = null;
    private SwitchRecyclerAdapter mAdapter = null;
 
    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_recycler_switch);
 
        init();
        initLayout();
    }
 
    private void init() {
        mDataList = new ArrayList<>();
        mDataList.add(new SwitchItemVO("Test1", true));
        mDataList.add(new SwitchItemVO("Test2", false));
        mDataList.add(new SwitchItemVO("Test3", true));
        mDataList.add(new SwitchItemVO("Test4", false));
        mDataList.add(new SwitchItemVO("Test5", true));
    }
 
    private void initLayout() {
        recyclerView = (RecyclerView) findViewById(R.id.recycler);
        layoutMgr = new LinearLayoutManager(getApplicationContext());
        recyclerView.setLayoutManager(layoutMgr);
 
        mAdapter = new SwitchRecyclerAdapter(this, mDataList);
        recyclerView.setAdapter(mAdapter);
        mAdapter.setOnCheckedChangeListener(mOnCheckedChangeListener);
        mAdapter.setOnClickListener(mOnClickedListener);
    }
 
    private SwitchRecyclerAdapter.OnCheckedChangeListener mOnCheckedChangeListener = new SwitchRecyclerAdapter.OnCheckedChangeListener() {
 
        @Override
        public void onCheckedChanged(int position, boolean isChecked) {
            Log.e("", ">>> position : " + position + ", isChecked : " + isChecked);
        }
    };
 
    private SwitchRecyclerAdapter.OnItemClickedListener mOnClickedListener = new SwitchRecyclerAdapter.OnItemClickedListener() {
        @Override
        public void onItemClicked(SwitchItemVO vo, int position) {
            Log.e("", ">>>  vo : " + vo.getTitle() + ", position : " + position);
        }
    };
}
