Android--Java code settings margin

We can usually set the margin directly in XML, such as:

<android:layout_margin= "5dip"  android:src= "@drawable/image"  />

However, in some cases, it is necessary to write in Java code, but the view itself does not have a setmargin method, how to do?

By looking at the Android API, we found that Android.view.ViewGroup.MarginLayoutParams has a method SetMargins (left, top, right, bottom).

Its direct subclasses are: Framelayout.layoutparams, Linearlayout.layoutparams and Relativelayout.layoutparams.

How to use:

New linearlayout.layoutparams (LinearLayout.LayoutParams.WRAP_CONTENT, LinearLayout.LayoutParams.WRAP_CONTENT);  Lp.setmargins (ten);  IMAGEVIEW.SETLAYOUTPARAMS (LP);

If this method has no effect, you can use the control to modify the margin, such as the previous ImageView, there is a GetLayout method, the layout obtained in the strong to linearlayout or other, and then set the margin.
