SwipeListener的ListView和ClickListener在ListView的项目 [英] SwipeListener on ListView and ClickListener on ListView's items

问题描述

这是我的<一个href=\"http://stackoverflow.com/questions/32022717/disable-listview-items-listeners/32022964#32022964\">old问题。我提供我的code以及但是这个时候。

This is my old question. However this time I have provided my code as well.

我有不同类型的行一个ListView。该行可能包含文字，图片，视频或其他什么东西。如果我点击的ImageView（行内）我会去另一个活动来显示图像全屏，如果我的视频点击（行内）我会去另一个活动中发挥他的视频。

I have a ListView with different types of rows. The row may contain text, image, video or something else. If I click on ImageView (inside the row) I will go to another activity to show the image in full screen, If I click on Video (inside the row) I will go to another activity to play he video.

我已经正确实施向左轻扫听众对我的ListView。如果我在ListView中的空白区域开始的ListView刷卡，刷一下工作（在下面的图像的第一和第二行）。但是，如果我开始从ListView控件行的项目在ListView轻扫，然后刷卡不工作（在下面的图像第三和第四行）。如果我删除的ImageView和视频的点击事件，然后轻扫工程，即使我开始从ListView控件行的项目即刷卡在这种情况下，刷卡作用于整个ListView的，不管在哪一行我做的刷卡。

I have implemented right to left swipe listener on my ListView. If I start the ListView swipe from an empty space in ListView, the swipe works (first and second row in below image). However if I start the ListView swipe from the ListView row's item, then the swipe doesn't work (third and fourth row in below image). If I remove the click events from ImageView and Video then the swipe works even if I start the swipe from the ListView row's item i.e. in this case the swipe works on whole ListView, no matter on which row I do the swipe.

我怎样才能摆脱对这个问题？我认为这是可以，如果我禁用内部ListView中所有项目的所有点击事件来实现。怎么可以这样做？有没有其他办法？

How can I get rid on this problem? I think this can be achieved if I disable all the click events on the all the items inside ListView. How can do so? Is there any other way?

我想要的ListView都刷卡，然后点击ListView的项目。

I want both swipe on ListView and click on ListView's item.

SwipeDetector.java - 有关的ListView检测挥笔

SwipeDetector.java - For detecting swipes on the ListView

public class SwipeDetector implements View.OnTouchListener {

private SwipeListener swipeListener;
private ListView mListView;
private int hundred;
private boolean motionInterceptDisallowed = false;

public static enum Action {
    LR, // Left to right
    RL, // Right to left
    TB, // Top to bottom
    BT, // Bottom to top
    None // Action not found
}

private static final int HORIZONTAL_MIN_DISTANCE = 30; // The minimum
// distance for
// horizontal swipe
private static final int VERTICAL_MIN_DISTANCE = 80; // The minimum distance
// for vertical
// swipe
private float downX, downY, upX, upY; // Coordinates
private Action mSwipeDetected = Action.None; // Last action

public SwipeDetector(Context context, ListView listView) {
    hundred = (int) context.getResources().getDimension(R.dimen.hundred);
    mListView = listView;
}

public boolean swipeDetected() {
    return mSwipeDetected != Action.None;
}

public Action getAction() {
    return mSwipeDetected;
}

/**
 * Swipe detection
 */@Override
public boolean onTouch(View v, MotionEvent event) {
    switch (event.getAction()) {
        case MotionEvent.ACTION_DOWN:
        {
            downX = event.getX();
            downY = event.getY();
            mSwipeDetected = Action.None;
            return false; // allow other events like Click to be processed
        }
        case MotionEvent.ACTION_MOVE:
        {
            upX = event.getX();
            upY = event.getY();

            float deltaX = downX - upX;
            float deltaY = downY - upY;

            float absX = Math.abs(deltaX);
            float absY = Math.abs(deltaY);

            if((absX >= (3 * absY)) && absX > HORIZONTAL_MIN_DISTANCE && mListView != null && !motionInterceptDisallowed) {
                mListView.requestDisallowInterceptTouchEvent(true);
                motionInterceptDisallowed = true;
            }

            if((absX >= (3 * absY)) && absX <= hundred) {
                if (deltaX > 0) {
                    mSwipeDetected = Action.RL;
                    swipeListener.onSwipe(MotionEvent.ACTION_MOVE, Action.RL, absX);
                }
            }


            return false;
        }
        case MotionEvent.ACTION_UP:
            swipeListener.onSwipe(MotionEvent.ACTION_UP, Action.BT, 0);
            if (mListView != null) {
                mListView.requestDisallowInterceptTouchEvent(false);
                motionInterceptDisallowed = false;
            }
            return false;
        case MotionEvent.ACTION_CANCEL:
            return true;
    }
    return false;
}

/**
 * Set chat send listener
 * @param listener
 */
public void setSwipeListener(SwipeListener listener) {
    swipeListener = listener;
}

public interface SwipeListener {
    void onSwipe(int event, Action action, float x);
}

}

这是我如何在我的ListView设置SwipeDetector

This is how I am setting SwipeDetector on my ListView

final SwipeDetector swipeDetector = new SwipeDetector(SwipeActivity.this, mListView);
    swipeDetector.setSwipeListener(mSwipeListener);
    mListView.setOnTouchListener(swipeDetector);

我的活动工具 SwipeDetector.SwipeListener

下面被覆盖onSwipe（）方法

Below is overridden onSwipe() method

@Override
public void onSwipe(int event, SwipeDetector.Action action, float x) {
    switch (event) {
            case MotionEvent.ACTION_MOVE:
                System.out.println("list move");
                break;
            case MotionEvent.ACTION_UP:
                System.out.println("list up");
                break;
        }
}

在我的适配器我设置onClickListener（）对我TextView的，ImageView的和VideoView

In my adapter I am setting onClickListener() on my TextView, ImageView and VideoView

holder.mTextView.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View v) {
            System.out.println("item textview click");
        }
    });

holder.mImageView.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View v) {
            System.out.println("item imageview click");
        }
    });

holder.mVideoView.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View v) {
            System.out.println("item videoview click");
        }
    });

当我从ListView中的空白区域启动轻扫，ListView的刷卡侦听器捕获它。然而，当我从TextView的/ ImageView的/ VideoView启动刷卡则该视图的onClickListener被触发，而不是父母（ListView的）onTouchListener（）。

When I start the swipe from the empty area of ListView, the ListView's swipe listener captures it. However, when I start the swipe from the TextView/ImageView/VideoView then that View's onClickListener is fired instead of parent's (ListView's) onTouchListener().

我如何能实现相同的？我想，当我点击ListView的项目，然后该项目的onClick应该被解雇，当我刷上ListView的项目，然后ListView的onSwipe应该被解雇。

How can I implement the same? I want that when I click on ListView's item then that item's onClick should get fired and when I swipe on the ListView's item then ListView's onSwipe should get fired.

推荐答案

这就是不可能的两个 onClickListener 为列表项和 SwipeListener 为列表，因为它可以让模糊性出发考虑触摸它们之间

Thats Not Possible with both onClickListener for listitem and SwipeListener for List,because it gets Ambiguity between which View to Consider on touch

您使用 OnSwipeTouchListener 它实现了 onTouchListener

OnSwipeTouchListener.java

import android.view.GestureDetector;
import android.view.GestureDetector.SimpleOnGestureListener;
import android.view.MotionEvent;
import android.view.View;
import android.view.View.OnTouchListener;

public class OnSwipeTouchListener implements OnTouchListener {

    private final GestureDetector gestureDetector;

    public OnSwipeTouchListener (Context ctx){
        gestureDetector = new GestureDetector(ctx, new GestureListener());
    }

    private final class GestureListener extends SimpleOnGestureListener {

        private static final int SWIPE_THRESHOLD = 100;
        private static final int SWIPE_VELOCITY_THRESHOLD = 100;

        @Override
        public boolean onDown(MotionEvent e) {
            return true;
        }

        @Override
        public boolean onFling(MotionEvent e1, MotionEvent e2, float velocityX, float velocityY) {
            boolean result = false;
            try {
                float diffY = e2.getY() - e1.getY();
                float diffX = e2.getX() - e1.getX();
                if (Math.abs(diffX) > Math.abs(diffY)) {
                    if (Math.abs(diffX) > SWIPE_THRESHOLD && Math.abs(velocityX) > SWIPE_VELOCITY_THRESHOLD) {
                        if (diffX > 0) {
                            onSwipeRight();
                        } else {
                            onSwipeLeft();
                        }
                    }
                    result = true;
                } 
                else if (Math.abs(diffY) > SWIPE_THRESHOLD && Math.abs(velocityY) > SWIPE_VELOCITY_THRESHOLD) {
                        if (diffY > 0) {
                            onSwipeBottom();
                        } else {
                            onSwipeTop();
                        }
                    }
                    result = true;

            } catch (Exception exception) {
                exception.printStackTrace();
            }
            return result;
        }
    }

    public void onSwipeRight() {
    }

    public void onSwipeLeft() {
    }

    public void onSwipeTop() {
    }

    public void onSwipeBottom() {
    }
}

和使用 OnSwipeTouchListener 在列表项

  listitem.setOnTouchListener(new OnSwipeTouchListener() {

        public void onSwipeLeft() {
            //stuff to do list view left swipe 
            Toast.makeText(MyActivity.this, "left", Toast.LENGTH_SHORT).show();
        }


        public boolean onTouch(View v, MotionEvent event) {
            //stuff to do on list item click
            return gestureDetector.onTouchEvent(event);
        }
    });

}); //to get click events
