缩放视图在android系统布局 [英] Zoom a view over layout in android
问题描述
我用这个来放大我的布局，这工作了点击放大而不是捏放大，也是我想在放大这种布局的视图。这一观点是由被用来绘制在这个布局中的行帆布方法返回。现在我的布局缩放，而不是canvas元素。有人可以帮助我放大两个canvas元素和布局。在此先感谢好友。
I used this to zoom my layout this worked for click to zoom and not for pinch to zoom and also i want to zoom a view over this layout. That view is returned by canvas method that is used to draw a line over this layout. Now my layout is zooming and not the canvas element. Can someone help me to zoom both the canvas element and the layout. Thanks in advance buddy.
推荐答案
这个答案是放大作出的WebView加载图像和内容
在复制资产形象，创造资产的文件image.html
在code会有些什么样的这种
Copy an Image in Assets and create a file image.html in assets the code will be some what like this
<html>
<table>
<tr>
<td>
<img src="droid.jpg" width="304" height="228" alt="Hello">
</td>
</tr>
</table>
</html>
和Java编写的类下面code
and write the below code in java class
public class MainActivity extends Activity {
// declare a WebView object first
WebView mWebView = null;
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
// load view
mWebView = (WebView)findViewById(R.id.webView);
// (*) this line make uses of the Zoom control
mWebView.getSettings().setBuiltInZoomControls(true);
// simply, just load an image
mWebView.loadUrl("file:///android_asset/image.html");
}
}
