實作RecyclerView的Adapter-->MyAdapter.java
package recyclerview.android.hmkcode.com.recyclerview;
import android.support.v7.widget.RecyclerView;
import android.view.LayoutInflater;
import android.view.View;
import android.view.ViewGroup;
import android.widget.ImageView;
import android.widget.TextView;
import android.widget.Toast;
import com.squareup.picasso.Picasso;
/**
* Created by lp43 on 2014/8/4.
*/
public class MyAdapter extends RecyclerView.Adapter{
private ItemData[] itemsData;
public MyAdapter(ItemData[] itemsData) {
this.itemsData = itemsData;
}
@Override
public ViewHolder onCreateViewHolder(ViewGroup viewGroup, int i) {
// create a new view
View itemLayoutView = LayoutInflater.from(viewGroup.getContext()).inflate(R.layout.item_layout, null);
// create ViewHolder
ViewHolder viewHolder = new ViewHolder(itemLayoutView);
return viewHolder;
}
@Override
public void onBindViewHolder(ViewHolder viewHolder, int position) {
// - get data from your itemsData at this position
// - replace the contents of the view with that itemsData
viewHolder.txtViewTitle.setText(itemsData[position].getTitle());
// viewHolder.imgViewIcon.setImageResource(itemsData[position].getImageUrl());
Picasso.with(viewHolder.imgViewIcon.getContext()).cancelRequest(viewHolder.imgViewIcon);
Picasso.with(viewHolder.imgViewIcon.getContext()).load(itemsData[position].getImageUrl()).into(viewHolder.imgViewIcon);
}
// Return the size of your itemsData (invoked by the layout manager)
@Override
public int getItemCount() {
return itemsData.length;
}
// inner class to hold a reference to each item of RecyclerView
public static class ViewHolder extends RecyclerView.ViewHolder implements View.OnClickListener {
public TextView txtViewTitle;
public ImageView imgViewIcon;
public ViewHolder(View itemLayoutView) {
super(itemLayoutView);
itemLayoutView.setOnClickListener(this);
txtViewTitle = (TextView) itemLayoutView.findViewById(R.id.item_title);
imgViewIcon = (ImageView) itemLayoutView.findViewById(R.id.item_icon);
}
@Override
public void onClick(View view) {
Toast.makeText(view.getContext(), "position = " + getPosition(), Toast.LENGTH_SHORT).show();
}
}
}
在主頁面MyActivity.java實例化RecyclerView
package recyclerview.android.hmkcode.com.recyclerview;
import android.support.v7.app.ActionBarActivity;
import android.os.Bundle;
import android.view.Menu;
import android.view.MenuItem;
import android.support.v7.widget.DefaultItemAnimator;
import android.support.v7.widget.LinearLayoutManager;
import android.support.v7.widget.RecyclerView;
public class MyActivity extends ActionBarActivity {
private String[] sources = {
"http://lorempixel.com/600/250/",
"http://lorempixel.com/600/250/sports",
"http://lorempixel.com/600/200/sports/Dummy-Text",
"http://lorempixel.com/600/200/nature",
"http://lorempixel.com/600/200/food",
};
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_my);
// 1. get a reference to recyclerView
RecyclerView recyclerView = (RecyclerView) findViewById(R.id.recycler_view);
// this is data fro recycler view
ItemData[] itemsData = {
new ItemData("Delete",sources[0]),
new ItemData("Cloud",sources[1]),
new ItemData("Favorite",sources[2]),
new ItemData("Like",sources[3]),
new ItemData("Rating",sources[4]),
new ItemData("Delete",sources[0]),
new ItemData("Cloud",sources[1]),
new ItemData("Favorite",sources[2]),
new ItemData("Like",sources[3]),
new ItemData("Rating",sources[4])
};
// 2. set layoutManger
recyclerView.setLayoutManager(new LinearLayoutManager(this));
// 3. create an adapter
MyAdapter mAdapter = new MyAdapter(itemsData);
// 4. set adapter
recyclerView.setAdapter(mAdapter);
// 5. set item animator to DefaultAnimator
recyclerView.setItemAnimator(new DefaultItemAnimator());
}
@Override
public boolean onCreateOptionsMenu(Menu menu) {
// Inflate the menu; this adds items to the action bar if it is present.
getMenuInflater().inflate(R.menu.my, menu);
return true;
}
@Override
public boolean onOptionsItemSelected(MenuItem item) {
// Handle action bar item clicks here. The action bar will
// automatically handle clicks on the Home/Up button, so long
// as you specify a parent activity in AndroidManifest.xml.
int id = item.getItemId();
if (id == R.id.action_settings) {
return true;
}
return super.onOptionsItemSelected(item);
}
}
