在Android中以编程方式 *** 作XML布局

概述我们可以在Java代码中 *** 作Xml布局吗？我的意思是让我说我​​在Xml中有一个布局,想要创建它的对象并改变它的属性(比如在将它传递给setcontentveiw()方法之前添加一些子)publicclassIconExtensionLayoutActivityextendsActivity{@OverridepublicvoidonCreate(Bundlesave

我们可以在Java代码中 *** 作Xml布局吗？我的意思是让我说我​​在Xml中有一个布局,想要创建它的对象并改变它的属性(比如在将它传递给setcontentveiw()方法之前添加一些子)

public class IconExtensionLayoutActivity extends Activity {@OverrIDepublic voID onCreate(Bundle savedInstanceState) {    super.onCreate(savedInstanceState);    relativeLayout mcontainer = (relativeLayout)IconExtensionLayoutActivity.this.findVIEwByID(R.ID.mContainerIconExtension);    ScrollVIEw mScrollVIEw = (ScrollVIEw)IconExtensionLayoutActivity.this.findVIEwByID(R.ID.mRootIconExtension);    relativeLayout mRow1 = (relativeLayout)IconExtensionLayoutActivity.this.findVIEwByID(R.ID.Root_Layout_Iconset_One_ID);    relativeLayout mRow2 = (relativeLayout)IconExtensionLayoutActivity.this.findVIEwByID(R.ID.Root_Layout_Iconset_Two_ID);    relativeLayout mRow3 = (relativeLayout)IconExtensionLayoutActivity.this.findVIEwByID(R.ID.Root_Layout_Iconset_Three_ID);    setContentVIEw(mScrollVIEw.getID());}

}

我的Xml布局如下.

解决方法:

是的,您可以使用LayoutInflater来扩展xml的UI,然后您可以从xml获取UI元素.有权访问UI对象,您可以在其上添加额外的UI元素层,最后将它们设置为setContentVIEw()

LayoutInflater mInflater = LayoutInflater.from(this);  VIEw contentVIEw = mInflater.inflate(R.layout.main, null); linearLayout root = (linearLayout) contentVIEw.findVIEwByID(R.ID.root);// mContainerIconExtension in your caseroot.addVIEw(new TextVIEw(this));setContentVIEw(root);
