示例1: onScale
import android.view.ScaleGestureDetector; //导入方法依赖的package包/类
@Override
public boolean onScale( ScaleGestureDetector detector )
{
// Check if the detector is in progress in order to proceed
if(detector!=null && detector.isInProgress() ){
try{
// Grab the scale
float targetScale = getScale() * detector.getScaleFactor();
// Correct for the min scale
targetScale = Math.min( maxZoom(), Math.max( targetScale, 1.0f) );
// Zoom and invalidate the view
zoomTo( targetScale, detector.getFocusX(), detector.getFocusY() );
invalidate();
return true;
}catch(IllegalArgumentException e){
e.printStackTrace();
}
