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

android:orientation="vertical"

android:background="@drawable/recycler_item_selector"

android:layout_width="match_parent"

android:layout_height="wrap_content">

android:id="@+id/textView"

android:layout_width="match_parent"

android:layout_height="wrap_content"

android:gravity="center"

android:textSize="40sp"

android:text="aaaa"/>

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

android:color="@color/colorPrimary">

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());

}

}

/**

* item点击接口

*/

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);

}

}
