支持手势滑动的ViewFlipper(动态导入)

好的，我可以为您提供一个支持手势滑动的ViewFlipper的实现，下面是具体步骤：

1. 首先，在您的项目中，添加以下依赖项：

implementation 'com.android.support:support-core-utils:28.0.0'
implementation 'com.android.support:support-v4:28.0.0'

2. 接着，在您的布局文件中添加如下代码：

<android.support.v4.widget.ViewDragHelper layout_height="match_parent"
    layout_width="match_parent"
    id="@+id/drag_helper"
    android:layout_gravity="center">

    <ViewFlipper layout_height="match_parent"
        layout_width="match_parent"
        android:id="@+id/view_flipper">
        <!-- your views here -->
    </ViewFlipper>

</android.support.v4.widget.ViewDragHelper>

3. 在您的Activity或Fragment中，添加如下代码：

import android.os.Bundle;
import android.support.v4.widget.ViewDragHelper;
import android.support.v7.app.AppCompatActivity;
import android.view.MotionEvent;
import android.view.View;
import android.widget.ViewFlipper;

public class MainActivity extends AppCompatActivity {

    private ViewDragHelper mDragHelper;
    private ViewFlipper mViewFlipper;

    private float mLastX;
    private float mLastY;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);

        mDragHelper = ViewDragHelper.create(this, 1.0f, new ViewDragHelper.Callback() {
            @Override
            public boolean tryCaptureView(View child, int pointerId) {
                return mViewFlipper.getDisplayedChild() == 0;
            }

            @Override
            public int getViewHorizontalDragRange(View child) {
                return child.getWidth();
            }

            @Override
            public int clampViewPositionHorizontal(View child, int left, int dx) {
                final int leftBound = mViewFlipper.getPaddingLeft();
                final int rightBound = mViewFlipper.getWidth() - mViewFlipper.getPaddingRight() - child.getWidth();
                final int newLeft = Math.min(Math.max(left, leftBound), rightBound);
                return newLeft;
            }

            @Override
            public void onViewReleased(View releasedChild, float xvel, float yvel) {
                super.onViewReleased(releasedChild, xvel, yvel);

                if (mViewFlipper.getDisplayedChild() == 0 && releasedChild.getLeft() > mViewFlipper.getWidth() / 2) {
                    mViewFlipper.showNext();
                } else {
                    mViewFlipper.getChildAt(0).setTranslationX(0);
                    mViewFlipper.getChildAt(0).setTranslationY(0);
                    mDragHelper.settleCapturedViewAt(mViewFlipper.getPaddingLeft(), mViewFlipper.getPaddingTop());
                    mViewFlipper.invalidate();
                }
            }
        });

        mViewFlipper = findViewById(R.id.view_flipper);
    }

    @Override
    public boolean onTouchEvent(MotionEvent event) {
        mDragHelper.processTouchEvent(event);

        final float x = event.getX();
        final float y = event.getY();

        switch (event.getAction()) {
            case MotionEvent.ACTION_DOWN:
                mLastX = x;
                mLastY = y;
                break;

            case MotionEvent.ACTION_MOVE:
                final float dx = x - mLastX;
                final float dy = y - mLastY;

                if (mViewFlipper.getDisplayedChild() == 0 && Math.abs(dy) < Math.abs(dx)) {
                    mViewFlipper.getChildAt(0).setTranslationX(dx);
                    mViewFlipper.getChildAt(0).setTranslationY(0);
                    mViewFlipper.invalidate();
                }

                mLastX = x;
                mLastY = y;
                break;

            case MotionEvent.ACTION_UP:
                mViewFlipper.getChildAt(0).setTranslationX(0);
                mViewFlipper.getChildAt(0).setTranslationY(0);
                mViewFlipper.invalidate();
                break;
        }

        return true;
    }
}

这样，您就可以在您的应用程序中使用支持手势滑动的ViewFlipper了。
