android - 在 Framelayout 中相互重叠的两个布局之间滑动

Question

我想在包裹在框架布局中的两个线性布局之间滑动。一次，只有一个线性布局是可见的。我正在使用按钮来显示/隐藏它们。我想在其中实现滑动功能。我尝试了 ViewFliper，但没有用手指滑动。是否可以使用 ViewPager 来实现？

Answer 1

解决方案: 您需要使用 GestureDetector 来在您的 LinearLayout

上发生滑动时收到通知

请看GestureDetector供引用。

到目前为止，我已经在你的代码中应用了滑动，但我没有你的可绘制对象，所以我只使用了我的。剩下的东西已经为你准备好了。所以只需使用你的 xml 文件而不是我的。

示例:

主 Activity .java

package com.mehuljoisar.swipe;
import android.app.Activity;
import android.content.Intent;
import android.os.Bundle;
import android.view.GestureDetector;
import android.view.MotionEvent;
import android.view.View;
import android.view.View.OnTouchListener;
import android.view.animation.Animation;
import android.view.animation.AnimationUtils;
import android.widget.FrameLayout;
import android.widget.ImageView;
import android.widget.LinearLayout;
import android.widget.Toast;



public class MainActivity extends Activity {

private GestureDetector gesturedetector = null;

private Intent i;

private FrameLayout flContainer;
private LinearLayout ivLayer1,ivLayer2;

@Override
public void onCreate(Bundle savedInstanceState) {

    super.onCreate(savedInstanceState);

    setContentView(R.layout.acti);

    flContainer = (FrameLayout) findViewById(R.id.flContainer);
    ivLayer1 = (LinearLayout)findViewById(R.id.layTopUp);
    ivLayer2 = (LinearLayout)findViewById(R.id.layScratchCard);


    gesturedetector = new GestureDetector(new MyGestureListener());

    flContainer.setOnTouchListener(new OnTouchListener() {

        @Override
        public boolean onTouch(View v, MotionEvent event) {

            gesturedetector.onTouchEvent(event);

            return true;

        }

    });

}

public boolean dispatchTouchEvent(MotionEvent ev) {

    super.dispatchTouchEvent(ev);

    return gesturedetector.onTouchEvent(ev);

}

class MyGestureListener extends GestureDetector.SimpleOnGestureListener {

    private static final int SWIPE_MIN_DISTANCE = 20;

    private static final int SWIPE_MAX_OFF_PATH = 100;

    private static final int SWIPE_THRESHOLD_VELOCITY = 100;

    @Override
    public boolean onFling(MotionEvent e1, MotionEvent e2, float velocityX,

    float velocityY) {

        float dX = e2.getX() - e1.getX();

        float dY = e1.getY() - e2.getY();

        if (Math.abs(dY) < SWIPE_MAX_OFF_PATH &&

        Math.abs(velocityX) >= SWIPE_THRESHOLD_VELOCITY &&

        Math.abs(dX) >= SWIPE_MIN_DISTANCE) {

            if (dX > 0) {

                Toast.makeText(getApplicationContext(), "Right Swipe",
                        Toast.LENGTH_SHORT).show();
                //Now Set your animation

                if(ivLayer2.getVisibility()==View.GONE)
                {
                    Animation fadeInAnimation = AnimationUtils.loadAnimation(MainActivity.this, R.anim.slide_right_in);
                    ivLayer2.startAnimation(fadeInAnimation);
                    ivLayer2.setVisibility(View.VISIBLE);
                }
            } else {

                Toast.makeText(getApplicationContext(), "Left Swipe",
                        Toast.LENGTH_SHORT).show();

                if(ivLayer2.getVisibility()==View.VISIBLE)
                {
                    Animation fadeInAnimation = AnimationUtils.loadAnimation(MainActivity.this, R.anim.slide_left_out);
                    ivLayer2.startAnimation(fadeInAnimation);
                    ivLayer2.setVisibility(View.GONE);
                }

            }

            return true;

        } else if (Math.abs(dX) < SWIPE_MAX_OFF_PATH &&

        Math.abs(velocityY) >= SWIPE_THRESHOLD_VELOCITY &&

        Math.abs(dY) >= SWIPE_MIN_DISTANCE) {

            if (dY > 0) {

                Toast.makeText(getApplicationContext(), "Up Swipe",
                        Toast.LENGTH_SHORT).show();

            } else {

                Toast.makeText(getApplicationContext(), "Down Swipe",
                        Toast.LENGTH_SHORT).show();
            }

            return true;

        }

        return false;
