Java 图像视图填充空白视图寻呼机Android

我一直在学习本教程，但我不能让图像视图内视图页面在水平和垂直方向上填充完整的空间内视图页面。你知道怎么做吗

我已经在我的页面适配器中尝试了这个

mImageView.setAdjustViewBounds(true);
mImageView.setScaleType(ImageView.ScaleType.FIT_CENTER);

但还是没有运气：(

我的布局

<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:padding="2dp"
tools:context=".MainActivity" >

<RelativeLayout
    android:id="@+id/img_slideshow_layout"
    android:layout_width="fill_parent"
    android:layout_height="wrap_content"
    android:layout_marginTop="5dp"
    android:background="@drawable/img_border" >

    <android.support.v4.view.ViewPager
        android:id="@+id/view_pager"
        android:layout_width="match_parent"
        android:layout_height="150dp" />

    <TextView
        android:id="@+id/img_name"
        android:layout_width="fill_parent"
        android:layout_height="wrap_content"
        android:layout_below="@+id/indicator"
        android:background="#88343434"
        android:ellipsize="end"
        android:paddingBottom="2dp"
        android:paddingLeft="5dp"
        android:paddingRight="2dp"
        android:paddingTop="2dp"
        android:singleLine="true"
        android:textColor="#ededed" />

    <apps.modisku.com.modisku.helper.CirclePageIndicator
        android:id="@+id/indicator"
        android:layout_width="fill_parent"
        android:layout_height="wrap_content"
        android:layout_below="@+id/view_pager"
        android:padding="10dip" />
</RelativeLayout>

使用FrameLayout而不是RelativeLayout
试试看

<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:padding="3dp" >

    <ImageView
        android:id="@+id/image_display"
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        android:scaleType="fitXY"
        android:contentDescription="@string/txt_image_slider" />

</RelativeLayout>



希望它对您有用。
您的viewpager中有什么？是片段还是简单视图？您能分享您的适配器代码吗？请告诉我下面的解决方案是否适合您？谢谢。如果这是您的xml，它将是片段？嘿，您能分享您的适配器代码吗？我想玩一下有了这个。对我来说似乎是个有趣的问题。他们现在尝试一下，实际上有3 DP的填充。我已经删除了它，现在图像肯定会出现在整个屏幕上！为什么你要使用pagerAdapter为什么不使用FragmentPagerAdapter？还可以尝试使用mImageView.setScaleType（ImageView.ScaleType.FITXY）；
public class ImageSlideAdapter extends PagerAdapter {
    ImageLoader imageLoader = ImageLoader.getInstance();
    DisplayImageOptions options;
    private ImageLoadingListener imageListener;
    FragmentActivity activity;
    List<Product> products;
    HomeFragment homeFragment;

    public ImageSlideAdapter(FragmentActivity activity, List<Product> products,
                             HomeFragment homeFragment) {
        this.activity = activity;
        this.homeFragment = homeFragment;
        this.products = products;
        options = new DisplayImageOptions.Builder()
                .showImageOnFail(R.drawable.ic_error)
                .showStubImage(R.drawable.ic_launcher)
                .showImageForEmptyUri(R.drawable.ic_empty).cacheInMemory()
                .cacheOnDisc().showImageOnLoading(R.drawable.loadingicontransprant).build();

        imageListener = new ImageDisplayListener();
    }

    @Override
    public int getCount() {
        return products.size();
    }

    @Override
    public View instantiateItem(ViewGroup container, final int position) {
        LayoutInflater inflater = (LayoutInflater) activity
                .getSystemService(Activity.LAYOUT_INFLATER_SERVICE);
        View view = inflater.inflate(R.layout.vp_image, container, false);

        ImageView mImageView = (ImageView) view
                .findViewById(R.id.image_display);


       // mImageView.setLayoutParams(new ViewGroup.LayoutParams(mScreenWidth, ViewGroup.LayoutParams.WRAP_CONTENT));
        mImageView.setAdjustViewBounds(true);
        mImageView.setScaleType(ImageView.ScaleType.FIT_CENTER);
        mImageView.setOnClickListener(new View.OnClickListener() {

            @Override
            public void onClick(View v) {
                Bundle arguments = new Bundle();
                Fragment fragment = null;
                Log.d("position adapter", "" + position);
                Product product = (Product) products.get(position);
                arguments.putParcelable("singleProduct", product);

                // Start a new fragment
                fragment = new ProductDetailFragment();
                fragment.setArguments(arguments);

                FragmentTransaction transaction = activity
                        .getSupportFragmentManager().beginTransaction();
                transaction.replace(R.id.promofragment, fragment,
                        ProductDetailFragment.ARG_ITEM_ID);
                transaction.addToBackStack(ProductDetailFragment.ARG_ITEM_ID);
                transaction.commit();
            }
        });
        imageLoader.displayImage(
                ((Product) products.get(position)).getImageURL(), mImageView,
                options, imageListener);
        container.addView(view);
        return view;
    }

    @Override
    public void destroyItem(ViewGroup container, int position, Object object) {
        container.removeView((View) object);
    }

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

    private static class ImageDisplayListener extends SimpleImageLoadingListener {

        static final List<String> displayedImages = Collections
                .synchronizedList(new LinkedList<String>());

        @Override
        public void onLoadingComplete(String imageUri, View view,
                                      Bitmap loadedImage) {
            if (loadedImage != null) {
                ImageView imageView = (ImageView) view;
                boolean firstDisplay = !displayedImages.contains(imageUri);
                if (firstDisplay) {
                    FadeInBitmapDisplayer.animate(imageView, 500);
                    displayedImages.add(imageUri);
                 }
               }
           }
        }
    }

    Use FrameLayout instead of RelativeLayout

    <?xml version="1.0" encoding="utf-8"?>
    <FrameLayout 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">

    <ImageView
        android:id="@+id/image_display"
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        android:scaleType="fitXY"
        android:contentDescription="@string/txt_image_slider" />

       </FrameLayout>

<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:padding="3dp" >

    <ImageView
        android:id="@+id/image_display"
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        android:scaleType="fitXY"
        android:contentDescription="@string/txt_image_slider" />

</RelativeLayout>
