从RecyclerView.OnItemTouchListener传递MotionEvents到GestureDetectorCompat（sorted传递reverse=true）
我有一个实现RecyclerView.OnItemTouchListener的片段。如何 仅 将ReclickerView
事件和单击和Long-click运动事件
传递给GestureDetectorCompat。这就是说，我只想处理单击和长按，其余事件应该由RecyclerView处理，因为它通常会发生。我该如何设置？
public class MyFragment extends Fragment implements RecyclerView.OnItemTouchListener, GestureDetector.OnGestureListener { protected RecyclerView recyclerView; protected RecyclerView.Adapter adapter; protected LinearLayoutManager layoutManager; private GestureDetectorCompat detector; public MyFragment() { // Required empty public constructor } @Override public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) { View rootView = inflater.inflate(R.layout.myfrag, container, false); recyclerView = (RecyclerView) rootView.findViewById(R.id.recyclerview); layoutManager = new LinearLayoutManager(getActivity()); recyclerView.setLayoutManager(layoutManager); recyclerView.addOnItemTouchListener(this); adapter = new MyAdapter(myData)); recyclerView.setAdapter(adapter); return rootView; } @Override public boolean onDown(MotionEvent e) { return false; } @Override public void onShowPress(MotionEvent e) { } @Override public boolean onSingleTapUp(MotionEvent e) { return false; } @Override public boolean onScroll(MotionEvent e1, MotionEvent e2, float distanceX, float distanceY) { return false; } @Override public void onLongPress(MotionEvent e) { } @Override public boolean onFling(MotionEvent e1, MotionEvent e2, float velocityX, float velocityY) { return false; } @Override public boolean onInterceptTouchEvent(RecyclerView recyclerView, MotionEvent event) { return false; } @Override public void onTouchEvent(RecyclerView recyclerView, MotionEvent event) { }}答案1
小编典典您必须GestureDetectorCompat在onCreateView()方法中进行初始化：
@Overridepublic View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) { View rootView = inflater.inflate(R.layout.myfrag, container, false); detector = new GestureDetectorCompat(getActivity(), new RecyclerViewOnGestureListener()); recyclerView = (RecyclerView) rootView.findViewById(R.id.recyclerview); layoutManager = new LinearLayoutManager(getActivity()); recyclerView.setLayoutManager(layoutManager); recyclerView.addOnItemTouchListener(this); adapter = new MyAdapter(myData)); recyclerView.setAdapter(adapter); return rootView;}RecyclerViewOnGestureListener是您自己的内部类扩展SimpleOnGestureListener（提供OnGestureListener方法的空实现）
private class RecyclerViewOnGestureListener extends SimpleOnGestureListener { @Override public boolean onSingleTapConfirmed(MotionEvent e) { View view = recyclerView.findChildViewUnder(e.getX(), e.getY()); int position = recyclerView.getChildPosition(view); // handle single tap return super.onSingleTapConfirmed(e); } public void onLongPress(MotionEvent e) { View view = recyclerView.findChildViewUnder(e.getX(), e.getY()); int position = recyclerView.getChildPosition(view); // handle long press super.onLongPress(e); }}现在看一行（来自onCreateView()方法）：
recyclerView.addOnItemTouchListener(this);在我们的例子中，“ this” OnItemTouchListener包含两个我们需要实现的方法：
@Overridepublic boolean onInterceptTouchEvent(RecyclerView rv, MotionEvent e) { detector.onTouchEvent(e); return false;}@Overridepublic void onTouchEvent(RecyclerView rv, MotionEvent e) {}这是这些方法的含义的解释：https

您只需要处理来自的单击和长按事件即可RecyclerView。

Android ListView与OnItemClickListener和GestureDetector
我有一个以下ListActivity：
public class ShowDayActivity extends ListActivity implements OnItemClickListener {
private GestureDetector gestureDetector;
private View.OnTouchListener gestureListener;
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.day);
registerForContextMenu(getListView());
gestureDetector = new GestureDetector(new MyGestureDetector());
gestureListener = new View.OnTouchListener() {
@Override
public boolean onTouch(View v,MotionEvent event) {
return gestureDetector.onTouchEvent(event);
}
};
getListView().setonItemClickListener(this);
getListView().setonTouchListener(gestureListener);
}
@SuppressWarnings("static-access")
@Override
public boolean onoptionsItemSelected(MenuItem item) {
...
return super.onoptionsItemSelected(item);
}
@Override
public boolean onContextItemSelected(MenuItem item) {
...
return super.onContextItemSelected(item);
}
Override
public void onItemClick(AdapterView<?> parent,View v,int pos,long id) {
editEvent(pos);
}
class MyGestureDetector extends SimpleOnGestureListener {
private static final int SWIPE_MIN_disTANCE = 120;
private static final int SWIPE_MAX_OFF_PATH = 250;
private static final int SWIPE_THRESHOLD_VELociTY = 200;
@Override
public boolean onFling(MotionEvent e1,MotionEvent e2,float veLocityX,float veLocityY) {
if (Math.abs(e1.getY() - e2.getY()) > SWIPE_MAX_OFF_PATH) {
return false;
}
// right to left swipe
if (e1.getX() - e2.getX() > SWIPE_MIN_disTANCE && Math.abs(veLocityX) > SWIPE_THRESHOLD_VELociTY) {
Log.d("ICS-Calendar","Fling left");
return true;
} else if (e2.getX() - e1.getX() > SWIPE_MIN_disTANCE && Math.abs(veLocityX) > SWIPE_THRESHOLD_VELociTY) {
Log.d("ICS-Calendar","Fling right");
return true;
}
return false;
}
}
}
listItems上的contextListener(long-click)完美地工作.今天我添加了gestureListener和Detector,它也是这样,但是：
GestureDetector检测到一切都没有了,但是在完成了逻辑之后,会打开上下文菜单,这显然不是我想要的.任何想法我做错了,还是我可以做什么？
解决方法
通常,您需要调用cancelLongPress()方法,并检测到onFling后的所有视图的子项.但是对于AbsListView,这个方法什么也不做:(
但是我已经找到了解决方法：在onFling回调中,处理完所有内容后,为ListView对象执行下一步：
Event cancelEvent = Event.obtain(ev2);
cancelEvent.setAction(MotionEvent.ACTION_UP);
listView.onTouchEvent(cancelEvent);
Android RecyclerView 单击、长按事件：基于 OnItemTouchListener +GestureDetector 标准实现（二），封装抽取成通用工具类
Android RecyclerView 单击、长按事件：基于 OnItemTouchListener +GestureDetector 标准实现（二），封装抽取成通用工具类
我写的附录文章 2，介绍了 Android 如何基于 OnItemTouchListener +GestureDetector 实现单击、长按事件的监听，由于如今 RecyclerView 在 Android 开发是如此的普遍，以及 RecyclerView 的单击事件是如此的常用，如果像附录文章 2 那样把一堆事件监听写到业务逻辑代码里面，那得写多少遍重复代码！所以我把给 RecyclerView 添加点击事件的 Listener 抽取、封装成一个常用的工具栏类 RecyclerViewUtil。
在给一个 RecyclerView 添加单击事件时候，跟 ListView 的监听事件一样，只需要简单的写如下代码即可完成：
//第一步，先初始化RecyclerViewUtil，传入当前的RecyclerView对象和上下文指针this:Context
RecyclerViewUtil util=new RecyclerViewUtil(this,mRecyclerView);
//第二步，直接set
util.setOnItemClickListener(new RecyclerViewUtil.OnItemClickListener() {
@Override
public void onItemClick(int position, View view) {
//Toast.makeText(getApplicationContext(),position+" 单击",Toast.LENGTH_SHORT).show();
}
});
长按事件也类似：
//先初始化RecyclerViewUtil，传入当前的RecyclerView对象和上下文指针this:Context
RecyclerViewUtil util=new RecyclerViewUtil(this,mRecyclerView);
util.setOnItemLongClickListener(new RecyclerViewUtil.OnItemLongClickListener() {
@Override
public void onItemLongClick(int position, View view) {
//Toast.makeText(getApplicationContext(),position+" 长按",Toast.LENGTH_SHORT).show();
}
});
封装、抽取好的通用 RecyclerViewUtil.java 全部代码：
package zhangphil.app;
import android.content.Context;
import android.support.v7.widget.RecyclerView;
import android.view.GestureDetector;
import android.view.MotionEvent;
import android.view.View;
/**
* Created by Phil on 2016/11/19.
*/
public class RecyclerViewUtil {
private RecyclerView mRecyclerView = null;
private GestureDetector mGestureDetector = null;
private RecyclerView.SimpleOnItemTouchListener mSimpleOnItemTouchListener;
private OnItemClickListener mOnItemClickListener = null;
private OnItemLongClickListener mOnItemLongClickListener = null;
private Context context;
public RecyclerViewUtil(Context context, RecyclerView recyclerView) {
this.context = context;
this.mRecyclerView = recyclerView;
mGestureDetector = new GestureDetector(context, new GestureDetector.SimpleOnGestureListener() {
//长按事件
@Override
public void onLongPress(MotionEvent e) {
super.onLongPress(e);
if (mOnItemLongClickListener != null) {
View childView = mRecyclerView.findChildViewUnder(e.getX(), e.getY());
if (childView != null) {
int position = mRecyclerView.getChildLayoutPosition(childView);
mOnItemLongClickListener.onItemLongClick(position, childView);
}
}
}
//单击事件
@Override
public boolean onSingleTapUp(MotionEvent e) {
if (mOnItemClickListener != null) {
View childView = mRecyclerView.findChildViewUnder(e.getX(), e.getY());
if (childView != null) {
int position = mRecyclerView.getChildLayoutPosition(childView);
mOnItemClickListener.onItemClick(position, childView);
return true;
}
}
return super.onSingleTapUp(e);
}
});
mSimpleOnItemTouchListener = new RecyclerView.SimpleOnItemTouchListener() {
@Override
public boolean onInterceptTouchEvent(RecyclerView rv, MotionEvent e) {
if (mGestureDetector.onTouchEvent(e)) {
return true;
}
return false;
}
};
mRecyclerView.addOnItemTouchListener(mSimpleOnItemTouchListener);
}
public void setOnItemClickListener(OnItemClickListener l) {
mOnItemClickListener = l;
}
public void setOnItemLongClickListener(OnItemLongClickListener l) {
mOnItemLongClickListener = l;
}
//长按事件接口
public interface OnItemLongClickListener {
public void onItemLongClick(int position, View view);
}
//单击事件接口
public interface OnItemClickListener {
public void onItemClick(int position, View view);
}
}
使用时候直接把 RecyclerViewUtil.java 复制到自己的项目代码工程中即可。
