Android——ViewGroup的一个用法实例(转载)

找了很久，终于找到了。

<?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

 

 

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:

 

<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>

我用那个ActivityGroup增加view的时候会出现一个边框线，这个实在是不好看，请问有没有办法把这个边框线去掉？
