依赖如下：
maven { url 'https://jitpack.io' }
compile 'com.github.DingMouRen:LayoutManagerGroup:643fb71c8e'
1：EchelonLayoutManager(梯形布局)，示例代码如下(注意看下备注)：
public class CeShi extends AppCompatActivity {
private RecyclerView recyclerView;
private ArrayList arrayList;
@Override
protected void onCreate(@Nullable Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.ceshi);
recyclerView = findViewById(R.id.recycler);
arrayList = new ArrayList<>();
arrayList.add("第");
arrayList.add("第");
arrayList.add("第");
arrayList.add("第");
arrayList.add("第");
arrayList.add("第");
arrayList.add("第");
arrayList.add("第");
EchelonLayoutManager echelonLayoutManager = new EchelonLayoutManager(this);
Log.d("CeShi", "echelonLayoutManager.getVerticalSpace():" + echelonLayoutManager.getVerticalSpace());
//如果getVerticalSpace方法得到的值为0，那么就会出现java.lang.ArithmeticException: divide by zero异常，也就是除数不能为0异常，看源码可知
//在EchelonLayoutManager源码的layoutChild方法中要除getVerticalSpace，所以RecyclerView的layout_height属性不能为wrap_content,不然会报错，可以是
//match_parent或者是具体的数值。
recyclerView.setLayoutManager(echelonLayoutManager);
recyclerView.setAdapter(new ShiPeiQi());
}
class ShiPeiQi extends RecyclerView.Adapter {
@NonNull
@Override
public ShiTu onCreateViewHolder(@NonNull ViewGroup parent, int viewType) {
ShiTu shiTu = new ShiTu(LayoutInflater.from(CeShi.this).inflate(R.layout.item, null));
return shiTu;
}
@Override
public void onBindViewHolder(@NonNull ShiTu holder, int position) {
holder.textView.setText(arrayList.get(position) + position);
}
@Override
public int getItemCount() {
return arrayList.size();
}
}
public class ShiTu extends RecyclerView.ViewHolder {
private TextView textView;
private ImageView imageView;
ShiTu(View itemView) {
super(itemView);
textView = itemView.findViewById(R.id.textView);
imageView = itemView.findViewById(R.id.imageview);
}
}
}
2：SkidRightLayoutManager(右滑布局)，示例代码如下(内容和上面一样，就该了两行代码)：
...
SkidRightLayoutManager skidRightLayoutManager = new SkidRightLayoutManager(1.5f, 0.85f);
recyclerView.setLayoutManager(skidRightLayoutManager);
...
3：SlideLayoutManager(滑动布局)，示例代码如下
public class CeShi extends AppCompatActivity {
private RecyclerView recyclerView;
private ArrayList arrayList;
@Override
protected void onCreate(@Nullable Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.ceshi);
recyclerView = findViewById(R.id.recycler);
arrayList = new ArrayList<>();
arrayList.add("第");
arrayList.add("第");
arrayList.add("第");
arrayList.add("第");
arrayList.add("第");
arrayList.add("第");
arrayList.add("第");
arrayList.add("第");
ShiPeiQi shiPeiQi=new ShiPeiQi();
ItemTouchHelperCallback itemTouchHelperCallback=new ItemTouchHelperCallback(shiPeiQi,arrayList);
itemTouchHelperCallback.setOnSlideListener(new OnSlideListener() {
@Override
public void onSliding(RecyclerView.ViewHolder viewHolder, float ratio, int direction) {
if (direction == ItemConfig.SLIDING_LEFT) {
} else if (direction == ItemConfig.SLIDING_RIGHT) {
}
}
@Override
public void onSlided(RecyclerView.ViewHolder viewHolder, String o, int direction) {
if (direction == ItemConfig.SLIDED_LEFT) {
Toast.makeText(CeShi.this, "不喜欢", Toast.LENGTH_SHORT).show();
} else if (direction == ItemConfig.SLIDED_RIGHT) {
Toast.makeText(CeShi.this, "喜欢", Toast.LENGTH_SHORT).show();
}
}
@Override
public void onClear() {
Toast.makeText(CeShi.this, "没数据了", Toast.LENGTH_SHORT).show();
}
});
ItemTouchHelper itemTouchHelper=new ItemTouchHelper(itemTouchHelperCallback);
SlideLayoutManager slideLayoutManager = new SlideLayoutManager(recyclerView,itemTouchHelper);
itemTouchHelper.attachToRecyclerView(recyclerView);
recyclerView.setLayoutManager(slideLayoutManager);
recyclerView.setAdapter(shiPeiQi);
}
class ShiPeiQi extends RecyclerView.Adapter {
@NonNull
@Override
public ShiTu onCreateViewHolder(@NonNull ViewGroup parent, int viewType) {
ShiTu shiTu = new ShiTu(LayoutInflater.from(CeShi.this).inflate(R.layout.item, null));
return shiTu;
}
@Override
public void onBindViewHolder(@NonNull ShiTu holder, int position) {
holder.textView.setText(arrayList.get(position) + position);
}
@Override
public int getItemCount() {
return arrayList.size();
}
}
public class ShiTu extends RecyclerView.ViewHolder {
private TextView textView;
private ImageView imageView;
ShiTu(View itemView) {
super(itemView);
textView = itemView.findViewById(R.id.textView);
imageView = itemView.findViewById(R.id.imageview);
}
}
}
4：BannerLayoutManager(横幅布局)，示例代码如下
public class CeShi extends AppCompatActivity {
private RecyclerView recyclerView;
private ArrayList arrayList;
@Override
protected void onCreate(@Nullable Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.ceshi);
recyclerView = findViewById(R.id.recycler);
arrayList = new ArrayList<>();
arrayList.add("第");
arrayList.add("第");
arrayList.add("第");
arrayList.add("第");
arrayList.add("第");
arrayList.add("第");
arrayList.add("第");
arrayList.add("第");
BannerLayoutManager bannerLayoutManager = new BannerLayoutManager(this,recyclerView,4, OrientationHelper.VERTICAL);
bannerLayoutManager.setTimeSmooth(500f);
recyclerView.setLayoutManager(bannerLayoutManager);
recyclerView.setAdapter(new ShiPeiQi());
}
class ShiPeiQi extends RecyclerView.Adapter {
@NonNull
@Override
public ShiTu onCreateViewHolder(@NonNull ViewGroup parent, int viewType) {
ShiTu shiTu = new ShiTu(LayoutInflater.from(CeShi.this).inflate(R.layout.item, null));
return shiTu;
}
@Override
public void onBindViewHolder(@NonNull ShiTu holder, int position) {
holder.textView.setText(arrayList.get(position%8) + position);//这里需要取余，不然arrayList中没有无穷个数据。
}
@Override
public int getItemCount() {
return Integer.MAX_VALUE;//这里只有是无穷大，item才能不停的滚动
}
}
public class ShiTu extends RecyclerView.ViewHolder {
private TextView textView;
private ImageView imageView;
ShiTu(View itemView) {
super(itemView);
textView = itemView.findViewById(R.id.textView);
imageView = itemView.findViewById(R.id.imageview);
}
}
}
5：ViewPagerLayoutManager(视图页布局)，示例代码如下
...
ViewPagerLayoutManager viewPagerLayoutManager = new ViewPagerLayoutManager(this, OrientationHelper.VERTICAL);
viewPagerLayoutManager.setOnViewPagerListener(new OnViewPagerListener() {
@Override
public void onPageRelease(boolean b, int i) {
Toast.makeText(CeShi.this, "页面划出去了", Toast.LENGTH_SHORT).show();
}
@Override
public void onPageSelected(int i, boolean b) {
Toast.makeText(CeShi.this, "页面选择住了", Toast.LENGTH_SHORT).show();
}
@Override
public void onLayoutComplete() {
}
});
recyclerView.setLayoutManager(viewPagerLayoutManager);
...
