SwipeRefreshLayout disable drag animation on swipe down

Question

Is it possible to disable SwipeRefreshLayout drag animation on swipe down without class customization?

Answer 1

Try calling:

setEnabled(false)

on your SwipeRefreshLayout view.

Answer 2

Well, disabling SwipeLayoutAnimanion appeared to be a rather simple task, but it involves replication of android.support.v4.widget.SwipeRefreshLayout class inside one's project.

Diving in source code will reveal, that SwipeRefreshLayout consists of three classes:

• android.support.v4.widget.SwipeRefreshLayout
• android.support.v4.widget.SwipeProgressBar
• android.support.v4.widget.BakedBezierInterpolator

All three classes should be included in the project. Then SwipeRefreshLayout can be customized as follows:

Add a new public method which will control either layout should follow the swipe down gesture or not:

private boolean mLayoutMovementEnabled = true;

public void setLayoutMovementEnabled(boolean enabled) {
    mLayoutMovementEnabled = enabled;
}

All related computations are performed inside onTouchEvent(). To disable layout following the movement,

updateContentOffsetTop((int) (offsetTop)); string should be changed to

if (mLayoutMovementEnabled) updateContentOffsetTop((int) (offsetTop));

The complete modified routine is below.

@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;
}

Answer 3

One simple way to disable the swipe is to set the distance to trigger sync to some value too high to be reached.

mSwipeLayout.setDistanceToTriggerSync(999999);
