Question

我已经尝试在我的android项目中使用RecyclerView，一切正常，而不是轻扫触摸处理。我想要的是列表项下的自定义视图（主要是一些按钮）。请参见下面的截图： swipeable item background expectation

我已经找到了如何执行动画的方法，但我无法点击背景视图上的按钮。我想问题是我的touchlistener仍然想要执行滑动效果而不是点击事件，因为＆＃34;可滑动区域＆＃34;仍然是视图的完整宽度（前景和背景）。是否有任何已知的解决方法或最佳实践来处理主项目下的点击事件？或者我可以只前景可刷？

以下是我的代码段。

触摸听众：

public class TrainingListOnSwipeAndDragListener extends ItemTouchHelper.SimpleCallback {


private final MainActivity Activity;
private TrainingRoutineListAdapter Adapter;


public TrainingListOnSwipeAndDragListener(MainActivity activity, TrainingRoutineListAdapter adapter, int dragDirs, int swipeDirs) {
    super(dragDirs, swipeDirs);
    this.Activity = activity;
    this.Adapter = adapter;
}

@Override
public boolean isLongPressDragEnabled() {
    return true;
}

@Override
public boolean isItemViewSwipeEnabled() {
    return true;
}

@Override
public boolean onMove(RecyclerView recyclerView, RecyclerView.ViewHolder viewHolder, RecyclerView.ViewHolder target) {
    return Adapter.onItemMove(viewHolder.getAdapterPosition(), target.getAdapterPosition());
}

@Override
public void onSwiped(RecyclerView.ViewHolder viewHolder, int direction) {
}

@Override
public void onChildDraw(Canvas c, final RecyclerView recyclerView, final RecyclerView.ViewHolder viewHolder, float dX, float dY, int actionState, boolean isCurrentlyActive) {

    if(actionState == ItemTouchHelper.ACTION_STATE_SWIPE) {
        View itemView = ((RoutineViewHolder) viewHolder).Foreground;
        itemView.setTranslationX(dX / 2);
    }else{
        super.onChildDraw(c, recyclerView, viewHolder, dX, dY, actionState, isCurrentlyActive);
    }

}

}
