The use of Android to define its own label. Implement a flat UI design:
Define your own label in the 1.attrs.xml file
Such as:
<?xml version= "1.0" encoding= "Utf-8"?>
<resources>
<declare-styleable name= "First" >
Reference refers to a quote from String.xml.
<attr name= "name" format= "Reference"/>
<attr name= "Age" >
Flag is custom, similar to android:gravity= "top"
<flag name= "Child" value= "ten" ></flag>
<flag name= "Yong" value= "></flag>"
<flag name= "Oldman" value= "></flag>"
</attr>
Dimension refers to the content that is quoted from the Dimension.xml.
<attr name= "Testsize" format= "Dimension" ></attr>
</declare-styleable>
</resources>
2. Use your own definition label in the layout file. Assigning values to tag properties
Such as:
<linearlayout xmlns:android= "Http://schemas.android.com/apk/res/android"
Com.example.declarestyleabletest the root path of the package in the manifest file xmlns:test= "http://schemas.android.com/apk/res/ Com.example.declarestyleabletest "
Android:layout_width= "Match_parent"
android:layout_height= "Match_parent"
android:orientation= "Vertical" >
MyTest See below
<com.example.declarestyleabletest.mytest
Android:id= "@+id/tvtest"
Test:name= "@string/name"
Android:layout_width= "Fill_parent"
android:layout_height= "Wrap_content"
android:text= "@string/test"
Test:age= "Oldman"
Test:testsize= "@dimen/size"/>
</LinearLayout>
3.mytest.java: In the class can get the value assigned to the property in the layout file, after the value can be assigned to the TextView properties of the change style
Such as:
Package com.example.declarestyleabletest;
Import Android.content.Context;
Import Android.content.res.TypedArray;
Import Android.util.AttributeSet;
Import Android.widget.TextView;
public class MyTest extends TextView {
Public MyTest (context context, AttributeSet Attrs) {
Super (context, attrs);
TypedArray Tarray = context.obtainstyledattributes (Attrs,
R.styleable.first);
String name = tarray.getstring (r.styleable.first_name);
int age = Tarray.getint (r.styleable.first_age, 100);
int dimen = Tarray.getint (r.styleable.first_testsize, 110);
System.out.println ("Name:" + name + "Age:" + Age + "dimen:");
Multiplexing Styledattributes
Tarray.recycle ();
}
}
4. Use the changed-style view object in Main.activity through Id:tvtest, such as TextView in this example.
The following is attached to the two demo, the first for the simple self-defined label assignment and extraction, the second for the more complex Flatui flat UI implementation. We can take a look at it.
