定义自己的xml

1.在attr中定义自己的样式

<resources>

<declare-styleable name="Favorite">

<attr name="className" format="string" />

<attr name="packageName" format="string" />

<attr name="screen" format="string" />

<attr name="x" format="string" />

<attr name="y" format="string" />

</declare-styleable>

</resources>

2.定义自己的xml属性

<favorites xmlns:test="http://schemas.android.com/apk/res/com.android.google">为包名

<favorite test:className="com.test.contacts.DialtactsContactsEntryActivity"

test:packageName="com.test.contacts" test:screen="1" test:x="1"

test:y="3"></favorite>

<favorite test:className="com.google.test" test:packageName="com.test.hello"

test:screen="2" test:x="2" test:y="2"></favorite>

</favorites>

2。TypedArray a = this.obtainStyledAttributes(set,R.styleable.Favorite);//把xml中定义的属性 -->对于到set集合中的值集合

 String className=a.getString(R.styleable.Favorite_className);//得到对于的值

3.程序解析的例子

private void parserXml() throws XmlPullParserException, Throwable {

XmlResourceParser parser = getResources()

.getXml(R.xml.default_favorite);

AttributeSet set = Xml.asAttributeSet(parser);

depth = parser.getDepth();

System.out.println(depth);

int type;

while (((type = parser.next()) != XmlPullParser.END_TAG || parser

.getDepth() > depth)

&& type != XmlPullParser.END_DOCUMENT) {

if (type != XmlPullParser.START_TAG) {

continue;

}

TypedArray a = this.obtainStyledAttributes(set,

R.styleable.Favorite);

String name = parser.getName();

if (name.equals("favorite")) {

String packageName = a

.getString(R.styleable.Favorite_packageName);

String className = a.getString(R.styleable.Favorite_className);

String screen = a.getString(R.styleable.Favorite_screen);

String x = a.getString(R.styleable.Favorite_x);

String y = a.getString(R.styleable.Favorite_y);

System.out.println(packageName + "/t" + className + "/t"

+ screen + "/t" + x + "/t" + y);

}

   a.recycle();//

}

}
