我的形象不完全适应屏幕。上面和下面都是白色边框
我的图片有700x1002。
请有人帮我把这些边缘弄出来,使图像/容器完全适合屏幕吗?
layout.xml格式:

<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent"
    android:layout_height="match_parent" >

    <FrameLayout
        android:layout_width="match_parent"
        android:layout_height="wrap_content"

        <android.support.v4.view.ViewPager

        android:layout_height="wrap_content"
        android:layout_above="@+id/linearActions"

        <com.viewpagerindicator.CirclePageIndicator

            app:fillColor="#027CC3"
            app:pageColor="#CCCCCC" />
    </RelativeLayout>

</RelativeLayout>

我的适配器:
public class MyAdapter extends PagerAdapter {

    Activity activity;
    int imageArray[];

    public MyAdapter(Activity act, int[] imgArray) {
        imageArray = imgArray;
        activity = act;
    }

    public Object instantiateItem(View collection, int position) {
        ImageView view = new ImageView(activity);
        view.setLayoutParams(new LayoutParams(LayoutParams.MATCH_PARENT,
                LayoutParams.MATCH_PARENT));
        view.setScaleType(ScaleType.FIT_CENTER);
        view.setImageResource(imageArray[position]);
        ((ViewPager) collection).addView(view, 0);
        return view;
    }

     @Override
     public void destroyItem(View arg0, int arg1, Object arg2) {
      ((ViewPager) arg0).removeView((View) arg2);
     }

     @Override
     public boolean isViewFromObject(View arg0, Object arg1) {
      return arg0 == ((View) arg1);
     }

    @Override
    public int getCount() {
        return imageArray.length;
    }

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

最佳答案

尝试将view.setScaleType(ScaleType.FIT_CENTER);更改为view.setScaleType(ScaleType.CENTER_CROP);
