android – 如何使应用程序像Flipboard？

您可以使用ViewFlipper或viewPager API来实现它.
ICS上方支持ViewPager API.但是,对于情人版,你可以使用android.support-v4库.

对于View Flipper,您可以使用动画进行翻转.

ViewFlipper源代码::

import android.app.Activity;
    import android.os.Bundle;
    import android.view.GestureDetector;
    import android.view.MotionEvent;
    import android.view.Window;
    import android.view.WindowManager;
    import android.view.ViewGroup.LayoutParams;
    import android.view.animation.AnimationUtils;
    import android.widget.ImageView;
    import android.widget.ViewFlipper;

     public class ViewFlipperActivity extends Activity implements  android.view.GestureDetector.OnGestureListener {
/** Called when the activity is first created. */
private int[] imageID = { 
        R.drawable.a01,R.drawable.a02,R.drawable.a03,R.drawable.a04,R.drawable.a05,R.drawable.a06,R.drawable.a07,R.drawable.a08,R.drawable.a09,R.drawable.a010,R.drawable.a011
          };
private ViewFlipper viewFlipper = null;  
private GestureDetector gestureDetector = null;
@Override
public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    //Remove title bar
    this.requestwindowFeature(Window.FEATURE_NO_TITLE);
    //Remove notification bar
    this.getwindow().setFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN,WindowManager.LayoutParams.FLAG_FULLSCREEN);
    setContentView(R.layout.main);
    viewFlipper = (ViewFlipper) findViewById(R.id.viewflipper); 
    // gestureDetector Object is used to detect gesture events
    gestureDetector = new GestureDetector(this); 
    for (int i = 0; i < imageID.length; i++)  
    { 
        ImageView image = new ImageView(this);  
        image.setimageResource(imageID[i]);  
        image.setScaleType(ImageView.ScaleType.FIT_XY);
        viewFlipper.addView(image,new LayoutParams(  
                LayoutParams.FILL_PARENT,LayoutParams.FILL_PARENT));
    }
}
public boolean onDown(MotionEvent arg0) {
    // Todo Auto-generated method stub
    return false;
}
public boolean onFling(MotionEvent arg0,MotionEvent arg1,float arg2,float arg3) {
    // Todo Auto-generated method stub
    if (arg0.getX() - arg1.getX() > 120)  
    {  

        this.viewFlipper.setInAnimation(AnimationUtils.loadAnimation(this,R.anim.push_left_in));  
        this.viewFlipper.setoutAnimation(AnimationUtils.loadAnimation(this,R.anim.push_left_out));  
        this.viewFlipper.showNext();  
        return true;  
    }
    else if (arg0.getX() - arg1.getX() < -120)  
    {  
        this.viewFlipper.setInAnimation(AnimationUtils.loadAnimation(this,R.anim.push_right_in));  
        this.viewFlipper.setoutAnimation(AnimationUtils.loadAnimation(this,R.anim.push_right_out));  
        this.viewFlipper.showPrevIoUs();  
        return true;  
    }  
    return true;
}
public void onLongPress(MotionEvent arg0) {
    // Todo Auto-generated method stub

}
public boolean onScroll(MotionEvent arg0,float arg3) {
    // Todo Auto-generated method stub
    return false;
}
public void onShowPress(MotionEvent arg0) {
    // Todo Auto-generated method stub

}
public boolean onSingleTapUp(MotionEvent arg0) {
    // Todo Auto-generated method stub
    return false;
}
@Override  
public boolean onTouchEvent(MotionEvent event)  
{  
    return this.gestureDetector.onTouchEvent(event);  
}
 }

查看Flipper XML布局：

<ViewFlipper  
    android:id="@+id/viewflipper"  
    android:layout_width="fill_parent"  
    android:layout_height="fill_parent"/>

     </LinearLayout>

ViewPager源代码::

import android.app.Activity;
    import android.content.Context;
    import android.os.Bundle;
    import android.os.Parcelable;
    import android.support.v4.view.PagerAdapter;

    import android.view.Menu;
    import android.view.View;
    import android.widget.ImageView;

  public class MainActivity extends Activity  {


private ViewPager viewPager;
private static int NUM_AWESOME_VIEWS = 20;
private Context cxt;
private pageradapter adapter;;

@Override
public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);
    cxt = this;

    adapter = new pageradapter();
    viewPager = (ViewPager) findViewById(R.id.viewpager);
    viewPager.setAdapter(adapter);
}

@Override
public boolean onCreateOptionsMenu(Menu menu) {
    getMenuInflater().inflate(R.menu.activity_main,menu);
    return true;
}
      private class pageradapter extends PagerAdapter{


    @Override
    public int getCount() {
        return NUM_AWESOME_VIEWS;
    }

    /**
     * Create the page for the given position.  The adapter is responsible
     * for adding the view to the container given here,although it only
     * must ensure this is done by the time it returns from

     *
     * @param container The containing View in which the page will be shown.
     * @param position The page position to be instantiated.
     * @return Returns an Object representing the new page.  This does not

     */
    @Override
    public Object instantiateItem(View collection,int position) {
        ImageView iv = new ImageView(cxt);
        iv.setBackgroundResource(R.drawable.a01);
        ((ViewPager) collection).addView(iv,0);


        return iv;
    }

    /**
     * Remove a page for the given position.  The adapter is responsible
     * for removing the view from its container,although it only must ensure
     * this is done by the time it returns from {@link #finishUpdate()}.
     *
     * @param container The containing View from which the page will be removed.
     * @param position The page position to be removed.
     * @param object The same object that was returned by

     */
    @Override
    public void destroyItem(View collection,int position,Object view) {
        ((ViewPager) collection).removeView((ImageView) view);
    }



    @Override
    public boolean isViewFromObject(View view,Object object) {
        return view==((ImageView)object);
    }


    /**
     * Called when the a change in the shown pages has been completed.  At this
     * point you must ensure that all of the pages have actually been added or
     * removed from the container as appropriate.
     * @param container The containing View which is displaying this adapter's
     * page views.
     */
    @Override
    public void finishUpdate(View arg0) {}


    @Override
    public void restoreState(Parcelable arg0,ClassLoader arg1) {}

    @Override
    public Parcelable saveState() {
        return null;
    }

    @Override
    public void startUpdate(View arg0) {

    }


}



 }

viewPager XML布局::

<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
     xmlns:tools="http://schemas.android.com/tools"
     android:layout_width="match_parent"
      android:layout_height="match_parent" >


 <android.support.v4.view.ViewPager
android:id="@+android:id/viewpager"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
/>



  </RelativeLayout>
