我在Recyclerview(https://github.com/lsjwzh/RecyclerViewPager)的一项中添加了RecyclerViewPager。
我想在触摸RecyclerView时滚动它。
我试过了 :
View.OnTouchListener listener = new View.OnTouchListener() {
@Override
public boolean onTouch(View v, MotionEvent event) {
switch (event.getAction()) {
case MotionEvent.ACTION_MOVE:
case MotionEvent.ACTION_DOWN:
mRecyclerViewPager.requestDisallowInterceptTouchEvent(true);
break;
case MotionEvent.ACTION_UP:
case MotionEvent.ACTION_CANCEL:
mRecyclerViewPager.requestDisallowInterceptTouchEvent(false);
break;
}
return false;
}
};
mRecyclerView.setOnTouchListener(listener);
但是我有时只能滚动RecyclerView。
我认为可以通过在
NestedScrollingParent中实现RecyclerViewPager或在onTouchEvent中更改RecyclerViewPager来实现，但是我对它们并不熟悉。最佳答案
我遵循了使用Github documentation.配置和创建简单示例的步骤
主要 Activity XML
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout 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"
xmlns:app="http://schemas.android.com/apk/res-auto"
android:paddingBottom="@dimen/activity_vertical_margin"
android:paddingLeft="@dimen/activity_horizontal_margin"
android:paddingRight="@dimen/activity_horizontal_margin"
android:paddingTop="@dimen/activity_vertical_margin"
tools:context="com.stackoverflow.recyclerviewstack.MainActivity">
<com.lsjwzh.widget.recyclerviewpager.RecyclerViewPager
android:id="@+id/list"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:paddingLeft="1dp"
android:paddingRight="1dp"
app:rvp_triggerOffset="0.1"
app:rvp_singlePageFling="true"
android:clipToPadding="false"

</RelativeLayout>
主要 Activity 课
package com.stackoverflow.recyclerviewstack;
import android.support.v7.app.AppCompatActivity;
import android.os.Bundle;
import android.support.v7.widget.LinearLayoutManager;
import com.lsjwzh.widget.recyclerviewpager.RecyclerViewPager;
public class MainActivity extends AppCompatActivity {
RecyclerAdapter mAdapter;
RecyclerViewPager mRecycler;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
mRecycler = (RecyclerViewPager) findViewById(R.id.list);
// setLayoutManager like normal RecyclerView, you do not need to change any thing.
LinearLayoutManager layout = new LinearLayoutManager(this, LinearLayoutManager.VERTICAL, false);
mRecycler.setLayoutManager(layout);
//set adapter
//You just need to implements ViewPageAdapter by yourself like a normal RecyclerView.Adpater.
mAdapter = new RecyclerAdapter(ItemListGenerator.generateCollection(15, "OutItem "));
mRecycler.setAdapter(mAdapter);
}
}
回收适配器
public class RecyclerAdapter extends RecyclerView.Adapter<RecyclerAdapter.ViewHolder> {
List<String> collection;
public RecyclerAdapter(List<String> collection) {
this.collection = collection;
}
public class ViewHolder extends RecyclerView.ViewHolder {
public TextView item;
RecyclerView mInnerRecycler;
public ViewHolder(View view) {
super(view);
item = (TextView) view.findViewById(R.id.title);
mInnerRecycler = (RecyclerView) view.findViewById(R.id.innerRecycler);
LinearLayoutManager layout = new LinearLayoutManager(view.getContext(),
LinearLayoutManager.HORIZONTAL, false);
mInnerRecycler.setLayoutManager(layout);
mInnerRecycler.setAdapter(new InnerAdapter());
}
}
@Override
public ViewHolder onCreateViewHolder(ViewGroup parent, int viewType) {
Context context = parent.getContext();
LayoutInflater inflater = LayoutInflater.from(context);
View view = inflater.inflate(R.layout.outer_collection, parent, false);
ViewHolder viewHolder = new ViewHolder(view);
return viewHolder;
}
@Override
public void onBindViewHolder(ViewHolder holder, int position) {
if(position < 0 || position > getItemCount()) return;
String itemString = collection.get(position);
holder.item.setText(itemString);
}
@Override
public int getItemCount() {
return collection.size();
}
}
RecyclerViewPager用于创建ViewHolder的布局
ViewHolder使用布局 outside_collection :
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="vertical" android:layout_width="match_parent"
android:layout_height="match_parent">
<TextView
android:id="@+id/title"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:padding="5dip"
android:layout_margin="2dip"
android:background="@color/colorPrimary"/>
<android.support.v7.widget.RecyclerView
android:id="@+id/innerRecycler"
android:layout_width="wrap_content"
android:layout_height="wrap_content"/>
</LinearLayout>
内部适配器
public class InnerAdapter extends RecyclerView.Adapter<InnerAdapter.ViewHolder> {
List<String> collection;
public InnerAdapter() {
this.collection = ItemListGenerator.generateCollection(15, "Inner ");
}
public class ViewHolder extends RecyclerView.ViewHolder {
public TextView item;
public ViewHolder(View itemView) {
super(itemView);
item = (TextView) itemView.findViewById(R.id.item);
}
}
@Override
public ViewHolder onCreateViewHolder(ViewGroup parent, int viewType) {
Context context = parent.getContext();
LayoutInflater inflater = LayoutInflater.from(context);
View view = inflater.inflate(R.layout.simple_item, parent, false);
ViewHolder viewHolder = new ViewHolder(view);
return viewHolder;
}
@Override
public void onBindViewHolder(ViewHolder holder, int position) {
if(position < 0 || position > getItemCount()) return;
holder.item.setText(collection.get(position));
}
@Override
public int getItemCount() {
return collection.size();
}
}
提示
对于RecyclerViewPager，我使用了以下方向:
LinearLayoutManager layout = new LinearLayoutManager(this, LinearLayoutManager.VERTICAL, false);
对于其中的RecyclerView:
LinearLayoutManager layout = new LinearLayoutManager(view.getContext(), LinearLayoutManager.HORIZONTAL, false);
如果在PagerView中使用VERTICAL，则可以在水平集合中导航或将PagerView方向更改为HORIZONTAL，并且可以在VERTICAL方向上滚动内部项目。
您必须评估如何使用它。我希望这段代码可以帮助您解决问题，并重新考虑您的设计。可能不是一个好习惯，或者UX对两个容器使用相同的方向。我不是UX专家。
我想提供更多帮助。
