如何在Android中制作动态翻转屏幕(如iPhone的动态翻转屏幕)

Question

我正在通过Web服务解析数据.我希望水平翻转而不是垂直翻转.这是一个使用ViewFlipper的教程,但它适用于静态数据.

这是我们的代码,我们需要在两个活动之间翻转:

Splash.java

public class Splash extends Activity{

        /** Called when the activity is first created. */

        public void onCreate(Bundle savedInstanceState) {
            super.onCreate(savedInstanceState);

            setContentView(R.layout.main);

                    startActivity(new Intent(Splash.this, MainMenu.class));
                    Splash.this.finish();                                     
        }
    }

Splash.xml

<?xml version="1.0" encoding="utf-8"?>
<AbsoluteLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:orientation="vertical"
    android:layout_width="fill_parent"
    android:layout_height="fill_parent"
    android:background="@drawable/splash">
</AbsoluteLayout>

Menu.java

public class Menu extends Activity{

        /** Called when the activity is first created. */

        public void onCreate(Bundle savedInstanceState) {
            super.onCreate(savedInstanceState);               
            setContentView(R.layout.menu);                                       
        }
    }

menu.xml文件

<?xml version="1.0" encoding="utf-8"?>
<AbsoluteLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:orientation="vertical"
    android:layout_width="fill_parent"
    android:layout_height="fill_parent"
    android:background="@drawable/menu">
</AbsoluteLayout>

Answer 1

您可以使用addView动态地将页面添加到ViewFlipper.

  flipper= (ViewFlipper) findViewById(R.id.flipper1);
  flipper.addView(myView,myViewIndex);

myView是您要添加的视图,myViewIndex是viewflipper中要添加此新视图的索引.

然后,您可以将动画设置为在更改视图时执行:

  flipper.setInAnimation(AnimationUtils.loadAnimation(this, R.anim.left_in));
  flipper.setOutAnimation(AnimationUtils.loadAnimation(this, R.anim.left_out));

然后翻到这个页面你可以使用:

  flipper.setDisplayedChild(myViewIndex);

其中left_in.xml定义为

<?xml version="1.0" encoding="utf-8"?>
<set xmlns:android="http://schemas.android.com/apk/res/android" 
  android:interpolator="@android:anim/accelerate_interpolator">
    <translate
    android:interpolator="@android:anim/decelerate_interpolator"
    android:fromXDelta="100%p"
    android:toXDelta="0" 
    android:duration="300"
    />
</set>

和left_out.xml是:

<?xml version="1.0" encoding="utf-8"?>
<set xmlns:android="http://schemas.android.com/apk/res/android" 
    android:interpolator="@android:anim/accelerate_interpolator"
    >
    <translate
    android:interpolator="@android:anim/decelerate_interpolator"
    android:fromXDelta="0" 
    android:toXDelta="-100%p" 
    android:duration="300"
    />
</set>
