Android――ViewGroup的一个用法实例(转载) 文章分类:移动开发
Xml代码
找了很久,终于找到了。
Xml代码
<?xml version="1.0" encoding="UTF-8" ?>
<merge xmlns:android=" http://schemas.android.com/apk/res/android"
xmlns:okCancelBar=" http://schemas.android.com/apk/res/com.example.android.merge">
<ImageView
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:scaleType="center"
android:src="@drawable/golden_gate"
/>
<com.example.android.merge.OkCancelBar
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:layout_gravity="bottom"
android:paddingTop="8dip"
android:gravity="center_horizontal"
android:background="#AA000000"
okCancelBar:okLabel="Save"
okCancelBar:cancelLabel="Don't save"
/>
</merge>
com.example.android.merge.OkCancelBar是一个自定义的GROUP
Java代码
public class OkCancelBar extends LinearLayout{
public OkCancelBar(Context context,AttributeSet attrs){
super(context, attrs);
setOrientation(HORIZONTAL);
setGravity(Gravity.CENTER);
setWeightSum(1.0f);
LayoutInflater.from(context).inflate(R.layout.okcancelbar,this,true);
TypedArray array= context.obtainStyledAttributes(attrs, R.styleable.OkCancelBar,0,0);
String text= array.getString(R.styleable.OkCancelBar_okLabel);
if(text==null) text="Ok";
((Button) findViewById(R.id.okcancelbar_ok)).setText(text);
text= array.getString(R.styleable.OkCancelBar_cancelLabel);
if(text==null) text="Cancel";
((Button) findViewById(R.id.okcancelbar_cancel)).setText(text);
array.recycle();
}
}
LayoutInflater.from(context).inflate(R.layout.okcancelbar,this,true);
直接从XML中得到一个VIEW加入到当前GROUP中
okcancelbar.xml:
Xml代码
<merge xmlns:android=" http://schemas.android.com/apk/res/android">
<include layout="@layout/okcancelbar_button" android:id="@+id/okcancelbar_ok"/>
<include layout="@layout/okcancelbar_button" android:id="@+id/okcancelbar_cancel"/>
</merge>
