スナックバーのスワイプして閉じる動作を無効にする方法

ユーザーがスナックバーをスワイプして閉じるのを防ぐ方法はありますか？

ネットワークログイン中にスナックバーを表示するアプリがありますが、却下されないようにしたいと思います。

Nikola Despotoskiの提案によると、私は両方のソリューションを実験しました。

private void startSnack(){

    loadingSnack = Snackbar.make(findViewById(R.id.email_login_form), getString(R.string.logging_in), Snackbar.LENGTH_INDEFINITE)
            .setAction("CANCEL", new OnClickListener() {
                @Override
                public void onClick(View view) {
                    getOps().cancelLogin();
                    enableControls();
                }
            });

    loadingSnack.getView().setOnTouchListener(new View.OnTouchListener() {
        public long mInitialTime;
        @Override
        public boolean onTouch(View v, MotionEvent event) {
            if (v instanceof Button) return false; //Action view was touched, proceed normally.
            else {
                switch (MotionEventCompat.getActionMasked(event)) {
                    case MotionEvent.ACTION_DOWN: {
                        Log.i(TAG, "ACTION_DOWN");
                        mInitialTime = System.currentTimeMillis();
                        break;
                    }
                    case MotionEvent.ACTION_UP: {
                        Log.i(TAG, "ACTION_UP");
                        long clickDuration = System.currentTimeMillis() - mInitialTime;
                        if (clickDuration <= ViewConfiguration.getTapTimeout()) {
                            return false;// click event, proceed normally
                        }
                    }
                    case MotionEvent.ACTION_MOVE: {
                        Log.i(TAG, "ACTION_MOVE");
                        return true;
                    }
                }
                return true;
            }
        }
    });

    ViewGroup.LayoutParams lp = loadingSnack.getView().getLayoutParams();
    if (lp != null && lp instanceof CoordinatorLayout.LayoutParams) {
        ((CoordinatorLayout.LayoutParams)lp).setBehavior(new DummyBehavior());
        loadingSnack.getView().setLayoutParams(lp);
        Log.i(TAG, "Dummy behavior assigned to " + lp.toString());

    }

    loadingSnack.show();

}

これはDummyBehaviorクラスです：

public class DummyBehavior extends CoordinatorLayout.Behavior<View>{

    /**
     * Debugging tag used by the Android logger.
     */
    protected final static String TAG =
            DummyBehavior.class.getSimpleName();



    public DummyBehavior() {
        Log.i(TAG, "Dummy behavior created");
        StackTraceElement[] stackTrace = Thread.currentThread().getStackTrace();
        Log.i(TAG, "Method " + stackTrace[2].getMethodName() );

    }

    public DummyBehavior(Context context, AttributeSet attrs) {
        super(context, attrs);
        Log.i(TAG, "Dummy behavior created");

    }

    @Override
    public boolean onInterceptTouchEvent(CoordinatorLayout parent, View child, MotionEvent ev) {
        Log.i(TAG, "Method " + Thread.currentThread().getStackTrace()[2].getMethodName() );
        return false;
    }

    @Override
    public boolean onTouchEvent(CoordinatorLayout parent, View child, MotionEvent ev) {
        Log.i(TAG, "Method " + Thread.currentThread().getStackTrace()[2].getMethodName() );
        return false;
    }

    @Override
    public boolean blocksInteractionBelow(CoordinatorLayout parent, View child) {
        Log.i(TAG, "Method " + Thread.currentThread().getStackTrace()[2].getMethodName() );
        return false;
    }

    @Override
    public boolean layoutDependsOn(CoordinatorLayout parent, View child, View dependency) {
        Log.i(TAG, "Method " + Thread.currentThread().getStackTrace()[2].getMethodName() );
        return false;
    }

    @Override
    public boolean onDependentViewChanged(CoordinatorLayout parent, View child, View dependency) {
        Log.i(TAG, "Method " + Thread.currentThread().getStackTrace()[2].getMethodName() );
        return false;
    }

    @Override
    public void onDependentViewRemoved(CoordinatorLayout parent, View child, View dependency) {
        Log.i(TAG, "Method " + Thread.currentThread().getStackTrace()[2].getMethodName() );
    }

    @Override
    public boolean isDirty(CoordinatorLayout parent, View child) {
        Log.i(TAG, "Method " + Thread.currentThread().getStackTrace()[2].getMethodName() );
        return false;
    }

    @Override
    public boolean onMeasureChild(CoordinatorLayout parent, View child, int parentWidthMeasureSpec, int widthUsed, int parentHeightMeasureSpec, int heightUsed) {
        Log.i(TAG, "Method " + Thread.currentThread().getStackTrace()[2].getMethodName() );
        return false;
    }

    @Override
    public boolean onLayoutChild(CoordinatorLayout parent, View child, int layoutDirection) {
        Log.i(TAG, "Method " + Thread.currentThread().getStackTrace()[2].getMethodName() );
        return false;
    }

    @Override
    public boolean onStartNestedScroll(CoordinatorLayout coordinatorLayout, View child, View directTargetChild, View target, int nestedScrollAxes) {
        Log.i(TAG, "Method " + Thread.currentThread().getStackTrace()[2].getMethodName() );
        return false;
    }

    @Override
    public void onNestedScrollAccepted(CoordinatorLayout coordinatorLayout, View child, View directTargetChild, View target, int nestedScrollAxes) {
        Log.i(TAG, "Method " + Thread.currentThread().getStackTrace()[2].getMethodName() );
    }

    @Override
    public void onStopNestedScroll(CoordinatorLayout coordinatorLayout, View child, View target) {
        Log.i(TAG, "Method " + Thread.currentThread().getStackTrace()[2].getMethodName() );
    }

    @Override
    public void onNestedScroll(CoordinatorLayout coordinatorLayout, View child, View target, int dxConsumed, int dyConsumed, int dxUnconsumed, int dyUnconsumed) {
        Log.i(TAG, "Method " + Thread.currentThread().getStackTrace()[2].getMethodName() );
    }

    @Override
    public void onNestedPreScroll(CoordinatorLayout coordinatorLayout, View child, View target, int dx, int dy, int[] consumed) {
        Log.i(TAG, "Method " + Thread.currentThread().getStackTrace()[2].getMethodName() );
    }

    @Override
    public boolean onNestedFling(CoordinatorLayout coordinatorLayout, View child, View target, float velocityX, float velocityY, boolean consumed) {
        Log.i(TAG, "Method " + Thread.currentThread().getStackTrace()[2].getMethodName() );
        return false;
    }

    @Override
    public boolean onNestedPreFling(CoordinatorLayout coordinatorLayout, View child, View target, float velocityX, float velocityY) {
        Log.i(TAG, "Method " + Thread.currentThread().getStackTrace()[2].getMethodName() );
        return false;
    }

    @Override
    public WindowInsetsCompat onApplyWindowInsets(CoordinatorLayout coordinatorLayout, View child, WindowInsetsCompat insets) {
        Log.i(TAG, "Method " + Thread.currentThread().getStackTrace()[2].getMethodName() );
        return null;
    }

    @Override
    public void onRestoreInstanceState(CoordinatorLayout parent, View child, Parcelable state) {
        Log.i(TAG, "Method " + Thread.currentThread().getStackTrace()[2].getMethodName() );
    }

    @Override
    public Parcelable onSaveInstanceState(CoordinatorLayout parent, View child) {
        Log.i(TAG, "Method " + Thread.currentThread().getStackTrace()[2].getMethodName() );
        return null;
    }
}

しかし、スワイプするとスナックバーが消えます。これは典型的なログです。

これは私のために働いた：

    Snackbar.SnackbarLayout layout = (Snackbar.SnackbarLayout) snackbar.getView();
    snackbar.setDuration(Snackbar.LENGTH_INDEFINITE);
    snackbar.show();
    layout.getViewTreeObserver().addOnGlobalLayoutListener(new ViewTreeObserver.OnGlobalLayoutListener() {
        @Override
        public void onGlobalLayout() {
            ViewGroup.LayoutParams lp = layout.getLayoutParams();
            if (lp instanceof CoordinatorLayout.LayoutParams) {
                ((CoordinatorLayout.LayoutParams) lp).setBehavior(new DisableSwipeBehavior());
                layout.setLayoutParams(lp);
            }
            if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.JELLY_BEAN) {
                layout.getViewTreeObserver().removeOnGlobalLayoutListener(this);
            } else {
                //noinspection deprecation
                layout.getViewTreeObserver().removeGlobalOnLayoutListener(this);
            }
        }
    });

DisableSwipeBehaviorの場所：

public class DisableSwipeBehavior extends SwipeDismissBehavior<Snackbar.SnackbarLayout> {
    @Override
    public boolean canSwipeDismissView(@NonNull View view) {
        return false;
    }
}

Snackbarは、setBehaviorメソッドを使用して、これを実際にサポートするようになりました。ここでの素晴らしい点は、以前は常にいくつかの動作が失われ、現在は保持されていることです。

パッケージが移動したため、「新しい」をインポートする必要があることに注意してください スナックバーパッケージのスナックバー 。

Snackbar.make(view, stringId, Snackbar.LENGTH_LONG)
    .setBehavior(new NoSwipeBehavior())
    .show();

class NoSwipeBehavior extends BaseTransientBottomBar.Behavior {

    @Override
    public boolean canSwipeDismissView(View child) {
      return false;
    }
}

これは私のために働いた：

Snackbar snackbar = Snackbar.make(findViewById(container), R.string.offers_refreshed, Snackbar.LENGTH_LONG);
    final View snackbarView = snackbar.getView();
    snackbar.show();

    snackbarView.getViewTreeObserver().addOnPreDrawListener(new ViewTreeObserver.OnPreDrawListener() {
        @Override
        public boolean onPreDraw() {
            snackbarView.getViewTreeObserver().removeOnPreDrawListener(this);
            ((CoordinatorLayout.LayoutParams) snackbarView.getLayoutParams()).setBehavior(null);
            return true;
        }
    });

幸運を！ :)

Snackbarビューをクリックするのではなく、ストリーミングタッチイベントを無効にすることができます。

mSnackBar.getView().setOnTouchListener(new View.OnTouchListener() {
            public long mInitialTime;
            @Override
            public boolean onTouch(View v, MotionEvent event) {
                if (v instanceof Button) return false; //Action view was touched, proceed normally.
                else {
                    switch (MotionEventCompat.getActionMasked(event)) {
                        case MotionEvent.ACTION_DOWN: {
                            mInitialTime = System.currentTimeMillis();
                            break;
                        }
                        case MotionEvent.ACTION_UP: {
                            long clickDuration = System.currentTimeMillis() - mInitialTime;
                            if (clickDuration <= ViewConfiguration.getTapTimeout()) {
                                return false;// click event, proceed normally
                            }
                        }
                    }
                    return true;
                }
            });

または、Snackbarの動作を空のCoordinatorLayout.Behaviorに置き換えることもできます。

public CouchPotatoBehavior extends CoordinatorLayout.Behavior<View>{

    //override all methods and don't call super methods. 

}

これは空の動作であり、何もしません。デフォルトのSwipeToDismissBehaviorはViewDragHelperを使用してタッチイベントを処理し、タッチイベントが発生すると却下されます。

 ViewGroup.LayoutParams lp = mSnackbar.getView().getLayoutParams();
 if (lp instanceof CoordinatorLayout.LayoutParams) {
     ((CoordinatorLayout.LayoutParams)lp).setBehavior(new CouchPotatoBehavior());
       mSnackbar.getView().setLayoutParams(lp);              
}

ここでのより良い解決策....スナックバーのビューとしてCoordinatorLayoutまたはその子を提供しないでください。

Snackbar.make(ROOT_LAYOUT , "No internet connection", Snackbar.LENGTH_INDEFINITE).show();

どこ ROOT_LAYOUTは、coordinatorlayoutまたはその子を除く任意のレイアウトである必要があります。

これは、ViewTreeObserverをいじる必要のないソリューションです。次のソリューションは、SDK26に基づいてKotlinで記述されていることに注意してください。

BaseTransientBottomBar

final void showView() {
    if (mView.getParent() == null) {
        final ViewGroup.LayoutParams lp = mView.getLayoutParams();

        if (lp instanceof CoordinatorLayout.LayoutParams) {
            // If our LayoutParams are from a CoordinatorLayout, we'll setup our Behavior
            final CoordinatorLayout.LayoutParams clp = (CoordinatorLayout.LayoutParams) lp;

            final Behavior behavior = new Behavior();
            behavior.setStartAlphaSwipeDistance(0.1f);
            behavior.setEndAlphaSwipeDistance(0.6f);
            behavior.setSwipeDirection(SwipeDismissBehavior.SWIPE_DIRECTION_START_TO_END);
            behavior.setListener(new SwipeDismissBehavior.OnDismissListener() {
                @Override
                public void onDismiss(View view) {
                    view.setVisibility(View.GONE);
                    dispatchDismiss(BaseCallback.DISMISS_EVENT_SWIPE);
                }

                @Override
                public void onDragStateChanged(int state) {
                    switch (state) {
                        case SwipeDismissBehavior.STATE_DRAGGING:
                        case SwipeDismissBehavior.STATE_SETTLING:
                            // If the view is being dragged or settling, pause the timeout
                            SnackbarManager.getInstance().pauseTimeout(mManagerCallback);
                            break;
                        case SwipeDismissBehavior.STATE_IDLE:
                            // If the view has been released and is idle, restore the timeout
                            SnackbarManager.getInstance()
                                    .restoreTimeoutIfPaused(mManagerCallback);
                            break;
                    }
                }
            });
            clp.setBehavior(behavior);
            // Also set the inset Edge so that views can dodge the bar correctly
            clp.insetEdge = Gravity.BOTTOM;
        }

        mTargetParent.addView(mView);
    }

    ...
}

メソッドBaseTransientBottomBarでshowViewのソースコードを調べると、layoutParamsがCoordinatorLayout.LayoutParamsの場合の動作が追加されます。動作をnullに戻すことで、これを元に戻すことができます。

ビューが表示される直前に動作が追加されるため、ビューが表示された後で元に戻す必要があります。

val snackbar = Snackbar.make(coordinatorLayout, "Hello World!", Snackbar.LENGTH_INDEFINITE)
snackbar.show()
snackbar.addCallback(object : BaseTransientBottomBar.BaseCallback<Snackbar>() {
    override fun onShown(transientBottomBar: Snackbar) {
        val layoutParams = transientBottomBar.view.layoutParams as? CoordinatorLayout.LayoutParams
        layoutParams?.let { it.behavior = null }
    }
})
