android-RecyclerView
引入RecyclerView包 compile ‘com.android.support:recyclerview-v7:25.1.0’
main_layout布局
<LinearLayout
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.example.recyclerviewtest.MainActivity">
<android.support.v7.widget.RecyclerView
android:id="@+id/recycler_view"
android:layout_width="match_parent"
android:layout_height="match_parent">
</android.support.v7.widget.RecyclerView>
</LinearLayout>fruit_item.xml
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="horizontal"
android:layout_width="match_parent"
android:layout_height="wrap_content">
<ImageView
android:id="@+id/fruit_image"
android:layout_width="wrap_content"
android:layout_height="wrap_content"/>
<TextView
android:id="@+id/fruit_name"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_gravity="center_vertical"
android:layout_marginLeft="10dp"/>
</LinearLayout>Fruit .class
public class Fruit {
private String name;
private int imageId;
public Fruit(String name, int imageId) {
this.name = name;
this.imageId = imageId;
public String getName() {
return name;
public int getImageId() {
return imageId;
}适配器 首先继承RecyclerView.Adapter
public class FruitAdapter extends RecyclerView.Adapter<FruitAdapter.ViewHolder> {
private List<Fruit> mFruitList;
static class ViewHolder extends RecyclerView.ViewHolder {
ImageView fruitImage;
TextView fruitName;
public ViewHolder(View itemView) {
super(itemView);
fruitImage = (ImageView) itemView.findViewById(R.id.fruit_image);
fruitName = (TextView) itemView.findViewById(R.id.fruit_name);
public FruitAdapter(List<Fruit> fruitList) {
mFruitList = fruitList;
@Override
public ViewHolder onCreateViewHolder(ViewGroup parent, int viewType) {
View view = LayoutInflater.from(parent.getContext())
.inflate(R.layout.fruit_item, parent, false);
ViewHolder holder = new ViewHolder(view);
return holder;
@Override
public void onBindViewHolder(ViewHolder holder, int position) {
Fruit fruit = mFruitList.get(position);
holder.fruitImage.setImageResource(fruit.getImageId());
holder.fruitName.setText(fruit.getName());
@Override
public int getItemCount() {
return mFruitList.size();
}MainActivity
private List<Fruit> fruitList = new ArrayList<>();oncreate
initFruits();
RecyclerView recyclerView = (RecyclerView) findViewById(R.id.recycler_view);
LinearLayoutManager layoutManager = new LinearLayoutManager(this);
recyclerView.setLayoutManager(layoutManager);
FruitAdapter adapter = new FruitAdapter(fruitList);
recyclerView.setAdapter(adapter);
private void initFruits() {
for (int i = 0; i < 2; i++) {
Fruit apple = new Fruit("appale", R.mipmap.ic_launcher);
fruitList.add(apple);
Fruit banana = new Fruit("banana", R.mipmap.ic_launcher);
fruitList.add(banana);
Fruit orange = new Fruit("orange", R.mipmap.ic_launcher);
fruitList.add(orange);
Fruit watermelon = new Fruit("watermelon", R.mipmap.ic_launcher);
fruitList.add(watermelon);
Fruit pear = new Fruit("pear", R.mipmap.ic_launcher);
fruitList.add(pear);
Fruit grape = new Fruit("grape", R.mipmap.ic_launcher);
fruitList.add(grape);
Fruit pineapple = new Fruit("pineapple", R.mipmap.ic_launcher);
fruitList.add(pineapple);
Fruit strawberry = new Fruit("strawberry", R.mipmap.ic_launcher);
fruitList.add(strawberry);
Fruit cherry = new Fruit("cherry", R.mipmap.ic_launcher);
fruitList.add(cherry);
Fruit Mango = new Fruit("Mango", R.mipmap.ic_launcher);
fruitList.add(Mango);
}把垂直布局修改成水平
layoutManager.setOrientation(LinearLayoutManager.HORIZONTAL);修改布局item布局
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="vertical"
android:layout_width="100dp"
android:layout_height="wrap_content">
<ImageView
android:id="@+id/fruit_image"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_gravity="center_horizontal"/>
<TextView
android:id="@+id/fruit_name"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_gravity="center_horizontal"
android:layout_marginTop="10dp"/>
</LinearLayout>瀑布流
StaggeredGridLayoutManager layoutManager = new
StaggeredGridLayoutManager(3, StaggeredGridLayoutManager.VERTICAL);item布局
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="vertical"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_margin="5dp">
<ImageView
android:id="@+id/fruit_image"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_gravity="center_horizontal"/>
<TextView
android:id="@+id/fruit_name"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_gravity="left"
android:layout_marginTop="10dp"/>
