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);
}
}
