问题描述
如何创建与在缩放到适合整个滚动视图，并滚动一个ImageView的有一个小图像的画面填充滚动型的布局？例如。一个720x1280显示器具有全屏幕滚动视图（FILL_PARENT）。里面是一个的LinearLayout（FILL_PARENT）。在这是一个300x900位图中被放大后，以720x2160一个imageview的，充满屏幕宽度和超过垂直边界，并且可以在滚动视图/向下向上滚动
How do you create a layout with a screen-filling scrollview that has a small image in an imageview scaled to fit the whole scrollview and be scrollable? eg. A 720x1280 display has a full-screen scrollview (fill_parent). Inside is a linearlayout (fill_parent). In that is a 300x900 bitmap in an imageview that is upscaled to 720x2160, fills the screen width and exceeds the vertical bounds, and can be scrolled up/down in the scrollview.
该解决方案应该为所有屏幕尺寸合作，支持从移动多个设备到平板电脑。
The solution should work for all screen sizes to support multiple devices from mobiles to tablets.

这对我的作品：
<ScrollView 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" >
<LinearLayout
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical">
<ImageView
android:layout_width="720dp"
android:layout_height="2160dp"
android:src="@drawable/image"
android:scaleType="fitXY"/>
</LinearLayout>
</ScrollView>
如果您需要，使这项工作任何屏幕尺寸做到这一点编程方式：
If you need to make this work for any screen size do it programmatically:
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
imageView = (ImageView) findViewById(R.id.imageView);
Display display = getWindowManager().getDefaultDisplay();
Point size = new Point();
display.getSize(size);
int width = size.x;
int height = size.y;
imageView.getLayoutParams().width = width;
}
