前言：
最开始使用的HorizontalScrollView和ListView当数据量上去之后发现有些低性能的手机变得卡顿，手机屏幕刷新会黑屏（黑平的时候我都惊呆了）
实现
废话不多说了接下来实现功能，处于考虑我决定使用RecyclerView然后让他横向滑动并且让他们同步这样横向滑动就解决了，然后竖着滑动使用ScrollView，这就是我的思路。
RecyclerView Adapter 因为这里的item资源复用，渲染界面一定要仔细，不然一个界面变了会影响其他复用的界面
1.测试bean
public class Bean {
private String color;
private String name;
public String getColor() {
return color;
}
public void setColor(String color) {
this.color = color;
}
public String getName() {
return name;
}
public void setName(String name) {
this.name = name;
}
public Bean() {
}
}
2.界面布局
主activity
<?xml version="1.0" encoding="utf-8"?>
<androidx.constraintlayout.widget.ConstraintLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="match_parent"
tools:context=".MainActivity">
<ScrollView
android:layout_width="match_parent"
android:layout_height="match_parent">
<LinearLayout
android:id="@+id/box"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical">
</LinearLayout>
</ScrollView>
</androidx.constraintlayout.widget.ConstraintLayout>
RecyclerView item
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout
android:id="@+id/lay_item_auto_check_device"
xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:custom="http://schemas.android.com/apk/res-auto"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:gravity="center"
android:orientation="vertical">
<LinearLayout
android:layout_width="80dp"
android:layout_height="70dp"
android:background="@drawable/item_bg"
android:layout_margin="5dp"
android:gravity="center"
android:orientation="vertical">
<LinearLayout
android:id="@+id/item_background"
android:layout_width="60dp"
android:layout_height="55dp"
android:background="#e6e6e6"
android:orientation="vertical">
<TextView
android:id="@+id/item_textview"
android:layout_width="60dp"
android:layout_height="35dp"
android:gravity="center"
android:focusable="true"
android:focusableInTouchMode="false"
android:textColor="#ffffff"
android:textStyle="bold"
android:textSize="20dp"/>
</LinearLayout>
</LinearLayout>
</LinearLayout>
3.适配器
import java.util.List;
public class Adapter extends RecyclerView.Adapter<Adapter.ViewHolder> {
private List<Bean> list;
public Adapter(List<Bean> list) {
this.list = list;
}
@NonNull
@Override
public ViewHolder onCreateViewHolder(@NonNull ViewGroup parent, int viewType) {
View view = LayoutInflater.from(parent.getContext()).inflate(R.layout.item,parent,false);
ViewHolder holder = new ViewHolder(view);
return holder;
}
@Override
public void onBindViewHolder(@NonNull ViewHolder holder, int position) {
Bean bean = list.get(position);
holder.lay.setBackgroundColor(Color.parseColor(bean.getColor()));
holder.tv.setText(bean.getName());
}
@Override
public int getItemCount() {
return list.size();
}
public class ViewHolder extends RecyclerView.ViewHolder {
LinearLayout lay;
TextView tv;
public ViewHolder(@NonNull View itemView) {
super(itemView);
lay = itemView.findViewById(R.id.item_background);
tv = itemView.findViewById(R.id.item_textview);
}
}
}
4.avtivity 代码
public class MainActivity extends AppCompatActivity {
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
//1.获取控件
LinearLayout boxView = findViewById(R.id.box);
//2.生成模拟数据
List<Bean> list = new ArrayList<>();
for (int i = 0; i < 100; i++) {
Bean bean = new Bean();
bean.setName("TNT" + i);
switch (i % 10) {
case 0:
bean.setColor("#ffbd21");
break;
case 1:
bean.setColor("#99cc00");
break;
case 2:
bean.setColor("#ff002a");
break;
case 3:
bean.setColor("#57C5E8");
break;
case 4:
bean.setColor("#B0B0B0");
break;
case 5:
bean.setColor("#59B29C");
break;
case 6:
bean.setColor("#ff6b29");
break;
case 7:
bean.setColor("#00a0e9");
break;
case 8:
bean.setColor("#f0f66e");
break;
case 9:
bean.setColor("#FFA4A9");
break;
}
list.add(bean);
}
//3.根据数据生成界面
final List<RecyclerView> syncRecyclerViews = new ArrayList<>();
for (int i = 0; i < 10; i++) {
RecyclerView syncRecyclerView = new RecyclerView(this);
Adapter adapter = new Adapter(list);
LinearLayoutManager ms = new LinearLayoutManager(this);
ms.setOrientation(LinearLayoutManager.HORIZONTAL);
syncRecyclerView.setLayoutManager(ms);
syncRecyclerView.setAdapter(adapter);
syncRecyclerViews.add(syncRecyclerView);
syncRecyclerView.setOverScrollMode(View.OVER_SCROLL_NEVER);//取消边缘波浪样式
boxView.addView(syncRecyclerView);
//添加监听，使所有的RecyclerView保持同步
RecyclerView.OnScrollListener listener = new RecyclerView.OnScrollListener() {
@Override
public void onScrolled(RecyclerView recyclerView, int dx, int dy) {
for (RecyclerView item : syncRecyclerViews) {
if (recyclerView == item) {
continue;
}
item.clearOnScrollListeners();
item.scrollBy(dx, dy);
item.addOnScrollListener(this);
}
}
};
syncRecyclerView.addOnScrollListener(listener);
}
}
}
