问题描述
我很想让我的开放源码库的触摸反馈。
I would love to enable touch feedback for my Open-Source library.
我已经创建了一个 RecyclerView 和 CardView 。该 CardView 包含了不同的的onClick 的行动不同的领域。现在，我会爱，如果用户单击该卡的任何地方引发连锁反应，但我不能够实现这种行为。
I've created a RecyclerView and a CardView. The CardView contains different areas with different onClick actions. Now I would love to trigger the Ripple effect if a user clicks anywhere in the card, but I'm not able to achieve this behavior.
这是我的列表项，你可以找到它在GitHub上过：https://github.com/mikepenz/AboutLibraries/blob/master/library/src/main/res/layout/listitem_opensource.xml

android:textSize="@dimen/textSizeSmall_openSource"/>
</LinearLayout>
</LinearLayout>
而的onClick 设置3份该布局。 libraryCreator ， libraryDescription 和 libraryBottomContainer 。
And the onClick is set on 3 parts of this layout. libraryCreator, libraryDescription, and libraryBottomContainer.
我希望有人得到了一个想法是怎么回事错在这里。
I hope someone got an idea what is going wrong here.
感谢您的帮助。
推荐答案
我现在能够解决这一问题。
I was now able to solve the issue.
现在的问题是，我使用onClickListener在TextViews这个点击监听器$ P $被告知了触摸事件pvents的RippleForeground。所以，解决的办法是落实这些TextViews的TouchListener，并通过触摸事件。
The problem is that i use onClickListener on the TextViews and this click listener prevents the RippleForeground from being notified about the touch event. So the solution is to implement an TouchListener on those TextViews and pass through the touch event.
类是非常简单的，并且可以在任何地方使用：
The class is really simple, and can be used everywhere:
package com.mikepenz.aboutlibraries.util;
import android.support.v7.widget.CardView;
import android.view.MotionEvent;
import android.view.View;
/**
* Created by mikepenz on 16.04.15.
*/
public class RippleForegroundListener implements View.OnTouchListener {
CardView cardView;
public RippleForegroundListener setCardView(CardView cardView) {
this.cardView = cardView;
return this;
}
@Override
public boolean onTouch(View v, MotionEvent event) {
// Convert to card view coordinates. Assumes the host view is
// a direct child and the card view is not scrollable.
float x = event.getX() + v.getLeft();
float y = event.getY() + v.getTop();
if (android.os.Build.VERSION.SDK_INT >= 21) {
// Simulate motion on the card view.
cardView.drawableHotspotChanged(x, y);
}
// Simulate pressed state on the card view.
switch (event.getActionMasked()) {
case MotionEvent.ACTION_DOWN:
cardView.setPressed(true);
break;
case MotionEvent.ACTION_UP:
case MotionEvent.ACTION_CANCEL:
cardView.setPressed(false);
break;
}
// Pass all events through to the host view.
return false;
}
}
有可用于通过添加此作为TouchListener：
It can be used by adding this as TouchListener:
RippleForegroundListener rippleForegroundListener = new RippleForegroundListener();
older.libraryCreator.setOnTouchListener(rippleForegroundListener);
这个监听器将只通过触摸事件的CardView并触发正确的连锁反应。 （您也可以修改该采取任何观点，它不应该被限制在CardView）
This listener will just pass through the touch event to the CardView and trigger the correct Ripple effect. (You can also modify this to take any view. It should not be limited to a CardView)
