对应xml代码：
<?xml version="1.0" encoding="utf-8"?><RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android" android:layout_width="match_parent" android:layout_height="match_parent" > <TextView android:id="@+id/text1" android:layout_width="wrap_content" android:layout_height="wrap_content" android:background="@drawable/tag_1" android:text="I'm label" android:textColor="#ffffff" /> <TextView android:id="@+id/text2" android:layout_width="wrap_content" android:layout_height="wrap_content" android:background="@drawable/tag_2" android:text="I'm label" android:textColor="#ffffff" /> <TextView android:id="@+id/text3" android:layout_width="wrap_content" android:layout_height="wrap_content" android:layout_centerVertical="true" android:background="@drawable/tag_3" android:text="I'm label" android:textColor="#ffffff" /> <TextView android:id="@+id/text4" android:layout_width="wrap_content" android:layout_height="wrap_content" android:background="@drawable/tag_4" android:text="I'm label" android:textColor="#ffffff" /> <TextView android:id="@+id/text5" android:layout_width="wrap_content" android:layout_height="wrap_content" android:background="@drawable/tag_5" android:text="I'm label" android:textColor="#ffffff" /> <TextView android:id="@+id/text6" android:layout_width="wrap_content" android:layout_height="wrap_content" android:layout_centerVertical="true" android:background="@drawable/tag_6" android:text="I'm label" android:textColor="#ffffff" /> <ImageView android:id="@+id/label_icon" android:layout_width="wrap_content" android:layout_height="wrap_content" android:layout_centerInParent="true" android:background="@drawable/dot" /></RelativeLayout>
应用：
private void initView(){ parentRL= (RelativeLayout) findViewById(R.id.parentRl); RelativeLayout.LayoutParams params= (RelativeLayout.LayoutParams) parentRL.getLayoutParams(); params.width= (int) PhoneSize.getInstance().getWidth4pix(); params.height=(int) PhoneSize.getInstance().getWidth4pix(); parentRL.setLayoutParams(params); ILabelView labelView=new ILabelView(ParentActivity.this); labelView.draw(parentRL,500,500);}
菜鸟一枚，有很多 不足之处请不吝指导。
