L'affichage de la carte flip animation sur de vieux android

Trouvé la réponse. Si vous voulez faire un flip animation sur ALL ANDROID VERSIONS, utilisez ceci:

De l'activité mise en page du fichier:

<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:id="@+id/main_activity_root"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:background="@android:color/transparent" >

<RelativeLayout
android:id="@+id/main_activity_card_face"
android:layout_width="300dp"
android:layout_height="407dp"
android:layout_centerHorizontal="true"
android:layout_centerVertical="true"
android:background="@drawable/front"
android:clickable="true"
android:onClick="onCardClick"
android:padding="5dp" >
</RelativeLayout>

<RelativeLayout
android:id="@+id/main_activity_card_back"
android:layout_width="300dp"
android:layout_height="407dp"
android:layout_centerHorizontal="true"
android:layout_centerVertical="true"
android:background="@drawable/back"
android:clickable="true"
android:onClick="onCardClick"
android:visibility="gone" >
</RelativeLayout>

</RelativeLayout>

Que le fichier de mise en page flips deux groupes, vous pouvez mettre autre chose à l'intérieur de la vue du groupe et cela devrait fonctionner. Regardons maintenant les méthodes à l'intérieur de l'activité qui s'occupe de l'appel de la flip code d'animation:

public void onCardClick(View view)
{
      flipCard();
}

private void flipCard()
{
    View rootLayout = findViewById(R.id.main_activity_root);
    View cardFace = findViewById(R.id.main_activity_card_face);
    View cardBack = findViewById(R.id.main_activity_card_back);

    FlipAnimation flipAnimation = new FlipAnimation(cardFace, cardBack);

    if (cardFace.getVisibility() == View.GONE)
    {
        flipAnimation.reverse();
    }
    rootLayout.startAnimation(flipAnimation);
}

Et enfin la FlipAnimation classe:

public class FlipAnimation extends Animation
{
private Camera camera;
private View fromView;
private View toView;
private float centerX;
private float centerY;
private boolean forward = true;
/**
* Creates a 3D flip animation between two views.
*
* @param fromView First view in the transition.
* @param toView Second view in the transition.
*/
public FlipAnimation(View fromView, View toView)
{
this.fromView = fromView;
this.toView = toView;
setDuration(700);
setFillAfter(false);
setInterpolator(new AccelerateDecelerateInterpolator());
}
public void reverse()
{
forward = false;
View switchView = toView;
toView = fromView;
fromView = switchView;
}
@Override
public void initialize(int width, int height, int parentWidth, int parentHeight)
{
super.initialize(width, height, parentWidth, parentHeight);
centerX = width/2;
centerY = height/2;
camera = new Camera();
}
@Override
protected void applyTransformation(float interpolatedTime, Transformation t)
{
//Angle around the y-axis of the rotation at the given time
//calculated both in radians and degrees.
final double radians = Math.PI * interpolatedTime;
float degrees = (float) (180.0 * radians / Math.PI);
//Once we reach the midpoint in the animation, we need to hide the
//source view and show the destination view. We also need to change
//the angle by 180 degrees so that the destination does not come in
//flipped around
if (interpolatedTime >= 0.5f)
{
degrees -= 180.f;
fromView.setVisibility(View.GONE);
toView.setVisibility(View.VISIBLE);
}
if (forward)
degrees = -degrees; //determines direction of rotation when flip begins
final Matrix matrix = t.getMatrix();
camera.save();
camera.rotateY(degrees);
camera.getMatrix(matrix);
camera.restore();
matrix.preTranslate(-centerX, -centerY);
matrix.postTranslate(centerX, centerY);
}

L'affichage de la carte flip animation sur de vieux android

Mise à JOUR de @FMMobileFelipeMenezes .

si vous souhaitez que l'animation d'une lisse à l'échelle de l'inverser, de modifier cette partie de code (applyTransformation) :

final Matrix matrix = t.getMatrix();
camera.save();
camera.translate(0, 0, Math.abs(degrees)*2);
camera.getMatrix(matrix);
camera.rotateY(degrees);
camera.getMatrix(matrix);
camera.restore();
matrix.preTranslate(-centerX, -centerY);
matrix.postTranslate(centerX, centerY);

Mise à JOUR de @Hesam
Il est bon tutoriel que je vous recommande de le lire. Bien qu'il n'est pas aussi beau que Android tutoriel basé sur des fragments, il vaut la peine d'être lu et utile si vous souhaitez affecter une animation pour les layouts et les vues ainsi que de l'avoir sur l'ancienne Api.

Utiliser Android animation d'échelle pour simuler un flip 3D

L'amélioration du projet sur github par @LenaBru

J'ai joué avec toute la journée, et enfin atteint le but ultime - une lisse cardflip comme la rotation de l'animation de deux points de vue!

J'ai mis du projet de démonstration ici

public class FlipAnimation extends Animation {
private Camera camera;
private View fromView;
private View toView;
private float centerX;
private float centerY;
private boolean forward = true;
/**
* Creates a 3D flip animation between two views.
* 
* @param fromView
*            First view in the transition.
* @param toView
*            Second view in the transition.
*/
public FlipAnimation(View fromView, View toView) {
this.fromView = fromView;
this.toView = toView;
setDuration(1500);
setFillAfter(false);
//setInterpolator(new AccelerateDecelerateInterpolator());
setInterpolator(new LinearInterpolator());
}
public void reverse() {
if (forward) {
View switchView = toView;
toView = fromView;
fromView = switchView;
}
forward = false;
}
@Override
public void initialize(int width, int height, int parentWidth, int parentHeight) {
super.initialize(width, height, parentWidth, parentHeight);
centerX = width / 2;
centerY = height / 2;
camera = new Camera();
}
@Override
protected void applyTransformation(float interpolatedTime, Transformation t) {
//Angle around the y-axis of the rotation at the given time
//calculated both in radians and degrees.
final double radians = Math.PI * interpolatedTime;
float degrees = (float) (180.0 * radians / Math.PI);
//scale down the views a bit, so that they would look nice when the rotation begins
if (interpolatedTime <= 0.05f) {
fromView.setScaleX(1 - interpolatedTime);
fromView.setScaleY(1 - interpolatedTime);
toView.setScaleX(1 - interpolatedTime);
toView.setScaleY(1 - interpolatedTime);
}
//Once we reach the midpoint in the animation, we need to hide the
//source view and show the destination view. We also need to change
//the angle by 180 degrees so that the destination does not come in
//It is very important to call "toView.bringToFront()" and not play with the
//visibility of the views, because if you apply this animation more than once,
//the subsequent calls may fail
if (interpolatedTime >= 0.5f) {
degrees -= 180.f;
toView.bringToFront();
//these two lines force a layout redraw
((View)toView.getParent()).requestLayout();
((View)toView.getParent()).invalidate();
}
//scale the views back to their original size (Assuming original size was 1)
if (interpolatedTime >= 0.95f) {
fromView.setScaleX(interpolatedTime);
fromView.setScaleY(interpolatedTime);
toView.setScaleX(interpolatedTime);
toView.setScaleY(interpolatedTime);
}
if (forward)
degrees = -degrees; //determines direction of rotation when flip
//begins
final Matrix matrix = t.getMatrix();
camera.save();
camera.translate(0, 0, Math.abs(degrees) * 2);
camera.getMatrix(matrix);
camera.rotateY(degrees);
camera.getMatrix(matrix);
camera.restore();
matrix.preTranslate(-centerX, -centerY);
matrix.postTranslate(centerX, centerY);
}
}

et de l'appeler comme ça

import android.content.Context;
import android.os.Bundle;
import android.os.Handler;
import android.support.v4.app.FragmentActivity;
import android.view.View;
import android.view.View.OnClickListener;
import android.widget.Toast;
public class MainActivity extends FragmentActivity {
private boolean showingBack;
private FragmentLeft left = new FragmentLeft();
private FragmentRight right = new FragmentRight();
private Context context;
private Handler handler;
private FlipAnimation flipAnimation;
private FlipAnimation backFlip;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
context = this;
handler = new Handler(getMainLooper());
getSupportFragmentManager().beginTransaction().add(R.id.fragment_container, right, "fragmentRight").commit();
getSupportFragmentManager().beginTransaction().add(R.id.fragment_container, left, "fragmentLeft").commit();
findViewById(R.id.flip).setOnClickListener(new OnClickListener() {
@Override
public void onClick(View v) {
flipAnimation = new FlipAnimation(left.getView(), right.getView());
backFlip = new FlipAnimation(left.getView(), right.getView());
handler.removeCallbacks(rotate);
handler.postDelayed(rotate, 100);
}
});
}
private Runnable rotate = new Runnable() {
@Override
public void run() {
//put a variable showingBack, do not rely on view properties to flip
if (!showingBack) {
//very important to flip both views, so that when the
//left view goes to back and right view goes to front,
//the right view finishes the rotation
left.getView().startAnimation(flipAnimation);
right.getView().startAnimation(flipAnimation);
Toast.makeText(context, "flip", Toast.LENGTH_LONG).show();
showingBack = true;
} else {
showingBack = false;
backFlip.reverse();
Toast.makeText(context, "backflip", Toast.LENGTH_LONG).show();
//very important to flip both views, so that when the
//right view goes to back and right view goes to front,
//the left view finishes the rotation
left.getView().startAnimation(backFlip);
right.getView().startAnimation(backFlip);
}
}
};
}

Ce sont les fragments

import android.os.Bundle;
import android.support.annotation.Nullable;
import android.support.v4.app.Fragment;
import android.view.LayoutInflater;
import android.view.View;
import android.view.ViewGroup;
public class FragmentRight extends Fragment {
@Override
public View onCreateView(LayoutInflater inflater, @Nullable ViewGroup container, @Nullable Bundle savedInstanceState) {
return inflater.inflate(R.layout.fragment_right, container,false);
}
}
import android.os.Bundle;
import android.support.annotation.Nullable;
import android.support.v4.app.Fragment;
import android.view.LayoutInflater;
import android.view.View;
import android.view.ViewGroup;
public class FragmentLeft extends Fragment {
@Override
public View onCreateView(LayoutInflater inflater, @Nullable ViewGroup container, @Nullable Bundle savedInstanceState) {
return inflater.inflate(R.layout.fragment_left, container,false);
}
}

et enfin la vue elle-même
