Question

如何使用电话和Tinder应用程序中的手势和动画滑动到上一个活动？

Answer 1

Telegram正在使用它自己创建的片段。他们创建了一个名为ActionBarLayout的类，它基本上是一个FrameLayout，并被添加到主Activity中，而片段只是一个视图类（称为TelegramFragment），它被添加到ActionBarLayout（它们保存在列表中，比正常的片段快得多（功能少一点）。

要制作动画，他们只需为添加的视图添加动画效果。

在github上有一个很好的库，我给了我的贡献：它通过活动和片段处理这个功能。

实际上你所要做的就是把这个 OnCreate:

getWindow().getDecorView().setBackgroundResource(android.R.color.transparent);
MIN_DISTANCE = TypedValue.applyDimension(TypedValue.COMPLEX_UNIT_DIP, 25, this.getResources().getDisplayMetrics());
rootView = (ViewGroup) ((ViewGroup) this .findViewById(android.R.id.content)).getChildAt(0);
rootView.post(new Runnable() { @Override public void run() {
        
        rootWidth = rootView.getWidth();
    } });
}
// Custom Variables
ViewGroup rootView ;
int rootWidth;
boolean enableSwipe= false;
boolean lockSwipe = false;
float downX;
float downY;
float MIN_DISTANCE ;
// Detect touch Events
 @Override public boolean dispatchTouchEvent(MotionEvent event) { 
switch(event.getAction()) { 
    case MotionEvent.ACTION_DOWN: 
    downX = event.getRawX();
    downY =event.getRawY();
    enableSwipe = false;
    lockSwipe = false;
    //convert activity to transparent
    
    try {   java.lang.reflect.Method getActivityOptions = Activity.class.getDeclaredMethod("getActivityOptions"); getActivityOptions.setAccessible(true); Object options = getActivityOptions.invoke(this); Class<?>[] classes = Activity.class.getDeclaredClasses(); Class<?> translucentConversionListenerClazz = null; for (Class clazz : classes) { if (clazz.getSimpleName().contains("TranslucentConversionListener")) { translucentConversionListenerClazz = clazz; } } 
        java.lang.reflect.Method convertToTranslucent = Activity.class.getDeclaredMethod("convertToTranslucent", translucentConversionListenerClazz, ActivityOptions.class); convertToTranslucent.setAccessible(true); convertToTranslucent.invoke(this, null, options); } catch (Throwable t) {
    }
    break; 
    case MotionEvent.ACTION_MOVE: 
    if (!lockSwipe){
        if(enableSwipe){
            float translation = event.getRawX() -downX - MIN_DISTANCE;
            if (translation >= rootWidth || translation<= 0){
                rootView.setTranslationX(0);
            }else{
                rootView.setTranslationX(translation);
            }
        }else{
            float translation = event.getRawX() -downX;
            if(Math.abs(event.getRawY() - downY) >= MIN_DISTANCE){
                enableSwipe = false;
                lockSwipe = true;
            }else{
                enableSwipe = event.getRawX() -downX >= MIN_DISTANCE;
            }
        }
    }
    break; 
    case MotionEvent.ACTION_UP: 
    if(rootView.getTranslationX() > rootWidth / 5){
        rootView.animate() 
        .translationX(rootWidth)
        .setListener(
        new AnimatorListenerAdapter() { 
                    @Override public void onAnimationEnd(Animator animation) { 
                
                    super.onAnimationEnd(animation);
                finish();
                overridePendingTransition(0, 0);
                
            } });
    }else{
        rootView.animate() 
        .translationX(0)
        .setListener(
        new AnimatorListenerAdapter() { 
                    @Override public void onAnimationEnd(Animator animation) { 
                super.onAnimationEnd(animation);
                // convert activity back to normal
                try {
                                java.lang.reflect.Method method = Activity.class.getDeclaredMethod("convertFromTranslucent");
                                method.setAccessible(true);
                                method.invoke(this);
                            } catch (Throwable t) {
                            }
            } });
        enableSwipe =false;
        lockSwipe = false;
    }
    break; 
    default:
    enableSwipe =false;
    lockSwipe = false;
    break; 
}
if (enableSwipe){
    // Event will not be passed to next views
    return true;
}
else{
    // Event will be passed to next views
    return super.dispatchTouchEvent(event); 
}
}
{

Android系统。滑动回电话之类的活动
