RecyclerView实现水波纹点击效果

本文实例为大家分享了RecyclerView实现水波纹点击效果的具体代码，供大家参考，具体内容如下

效果图

item.xml

这里就是主要设置background为我们后面写的一个selector

drawable-v21/recycler_item_selector.xml (v21版本以上)

drawable/recycler_item_selector.xml (v21版本以下的没有水波纹效果)

接下来是MyAdapter

public class MyAdapter extends RecyclerView.Adapter {


 private onRvItemClick mOnRvItemClick;
 private Context mContext;
 String[] strings;

 public MyAdapter(Context ctx, String[] strings, onRvItemClick onRvItemClick) {
  mContext = ctx;
  this.monRvItemClick = onRvItemClick;
  this.strings = strings;
 }

 @Override
 public ViewHolder onCreateViewHolder(ViewGroup parent, int viewType) {
  View view = LayoutInflater.from(mContext).inflate(R.layout.item, parent, false);
  return new ViewHolder(view);
 }

 @Override
 public void onBindViewHolder(ViewHolder holder, int position) {
  holder.setData(position);
 }

 @Override
 public int getItemCount() {
  return 20;
 }


 public class ViewHolder extends RecyclerView.ViewHolder implements View.onClickListener {
  @BindView(R.id.textView)
  TextView textView;

  public ViewHolder(View itemView) {
   super(itemView);
   ButterKnife.bind(this,itemView);
   itemView.setonClickListener(this);
  }

  public void setData(int position) {

   textView.setText("position" + position);
  }

  @Override
  public void onClick(View view) {
   if (monRvItemClick != null)
    mOnRvItemClick.onItemClick(view, getAdapterPosition());
  }

 }


 
 public interface onRvItemClick {
  void onItemClick(View v, int position);
 }
}

MainActivity

public class MainActivity extends AppCompatActivity {

 @BindView(R.id.RecyclerView)
 RecyclerView mRecyclerView;
 @Override
 protected void onCreate(Bundle savedInstanceState) {
  super.onCreate(savedInstanceState);
  setContentView(R.layout.activity_main);
  ButterKnife.bind(this);
  MyAdapter myAdapter = new MyAdapter(this, null, new MyAdapter.onRvItemClick() {
   @Override
   public void onItemClick(View v, int position) {
    Toast.makeText(getApplicationContext(), "click" + position, Toast.LENGTH_SHORT)
      .show();
   }
  });
  mRecyclerView.setLayoutManager(new LinearLayoutManager(this,LinearLayoutManager.VERTICAL,false));

  mRecyclerView.setAdapter(myAdapter);
 }
}
