SwipeRefreshLayout在向下滑动时禁用拖动animation
是否可以禁用SwipeRefreshLayout拖动animation不需要类定制？
尝试拨打：
setEnabled(false)
在您的SwipeRefreshLayout视图上。
那么，禁用SwipeLayoutAnimanion似乎是一个相当简单的任务，但它涉及到一个项目中android.support.v4.widget.SwipeRefreshLayout类的复制。
在源代码中潜水会发现， SwipeRefreshLayout由三个类组成：
- android.support.v4.widget.SwipeRefreshLayout
- android.support.v4.widget.SwipeProgressBar
- android.support.v4.widget.BakedBezierInterpolator
这三个class级都应该包含在项目中。 然后SwipeRefreshLayout可以自定义如下：
添加一个新的公共方法，将控制布局应该遵循向下滑动的手势：
private boolean mLayoutMovementEnabled = true; public void setLayoutMovementEnabled(boolean enabled) { mLayoutMovementEnabled = enabled; }
所有相关的计算都在onTouchEvent()内部执行。 要在移动后禁用布局，
updateContentOffsetTop((int) (offsetTop)); string应该改为
if (mLayoutMovementEnabled) updateContentOffsetTop((int) (offsetTop));
完整的修改例程如下。
@Override public boolean onTouchEvent(MotionEvent event) { final int action = event.getAction(); boolean handled = false; switch (action) { case MotionEvent.ACTION_DOWN: mCurrPercentage = 0; mDownEvent = MotionEvent.obtain(event); mPrevY = mDownEvent.getY(); break; case MotionEvent.ACTION_MOVE: if (mDownEvent != null && !mReturningToStart) { final float eventY = event.getY(); float yDiff = eventY - mDownEvent.getY(); if (yDiff > mTouchSlop) { // User velocity passed min velocity; trigger a refresh if (yDiff > mDistanceToTriggerSync) { // User movement passed distance; trigger a refresh startRefresh(); handled = true; break; } else { // Just track the user's movement setTriggerPercentage( mAccelerateInterpolator.getInterpolation( yDiff / mDistanceToTriggerSync)); float offsetTop = yDiff; if (mPrevY > eventY) { offsetTop = yDiff - mTouchSlop; } if (mLayoutMovementEnabled) updateContentOffsetTop((int) (offsetTop)); if (mPrevY > eventY && (mTarget.getTop() < mTouchSlop)) { // If the user puts the view back at the top, we // don't need to. This shouldn't be considered // cancelling the gesture as the user can restart from the top. removeCallbacks(mCancel); } else { updatePositionTimeout(); } mPrevY = event.getY(); handled = true; } } } break; case MotionEvent.ACTION_UP: case MotionEvent.ACTION_CANCEL: if (mDownEvent != null) { mDownEvent.recycle(); mDownEvent = null; } break; } return handled; }
一个简单的方法来禁用滑动是设置的距离触发同步到一些价值太高，无法达成。
mSwipeLayout.setDistanceToTriggerSync(999999);
