我正在xml文件中的ViewFlipper中使用三个imageview

i am using three imageview in ViewFlipper in xml file

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:orientation="vertical"

    </ViewFlipper>
</LinearLayout>

如何为这些imageView设置动态图像.通过使用单个ImageView.

How to set dynamic images to these imageView. By using single ImageView.

推荐答案

在您的xml中仅添加此内容，

In your xml just add only this,

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

不需要与任何ImageView一起封装.

need not enclose with any ImageViews.

现在在您的编码中执行此操作.

Now do this in your coding.

考虑到您已将图像存储在这样的数组中，

Considering that you have stored your Images in a array like this,

int gallery_grid_Images[]={R.drawable.gallery_image_1,R.drawable.gallery_image_2,R.drawable.gallery_image_3,
        R.drawable.gallery_image_4,R.drawable.gallery_image_5,R.drawable.gallery_image_6,R.drawable.gallery_image_7,
        R.drawable.gallery_image_8,R.drawable.gallery_image_9,R.drawable.gallery_image_10
        };

现在在您的onCreate()中，

Now in your onCreate(),

viewFlipper = (ViewFlipper) findViewById(R.id.flipper);
 for(int i=0;i<gallery_grid_Images.length;i++)
        {
        //  This will create dynamic image view and add them to ViewFlipper
            setFlipperImage(gallery_grid_Images[i]);
        }

现在将这种方法添加到您的活动中，

And now add this method to your activity,

private void setFlipperImage(int res) {
    Log.i("Set Filpper Called", res+"");
    ImageView image = new ImageView(getApplicationContext());
    image.setBackgroundResource(res);
    viewFlipper.addView(image);
}

就是这样.现在使用您的viewFlipper.showNext();和viewFlipper.showPrevious();您可以显示动态图像的方法.

That's it. And now using your viewFlipper.showNext(); and viewFlipper.showPrevious();methods you can show your dynamic images.
