这里只简单做了两个按钮的。

首先是两个按钮的背景：

res/drawable/seg_left.xml

<?xml version="1.0" encoding="utf-8"?><selector xmlns:android="http://schemas.android.com/apk/res/android" >    <item android:state_selected="true">        <shape >            <stroke android:color="#0079FF" android:width="1dp"/>            <solid android:color="#0079FF"/>            <corners android:topLeftRadius="3dp" android:bottomLeftRadius="3dp" android:topRightRadius="0dp" android:bottomRightRadius="0dp"/>        </shape>    </item>    <item>        <shape >            <stroke android:color="#0079FF" android:width="1dp"/>            <solid android:color="#FFFFFF"/>            <corners android:topLeftRadius="3dp" android:bottomLeftRadius="3dp" android:topRightRadius="0dp" android:bottomRightRadius="0dp"/>        </shape>    </item></selector>

<?xml version="1.0" encoding="utf-8"?><selector xmlns:android="http://schemas.android.com/apk/res/android" >    <item android:state_selected="true">        <shape >            <stroke android:color="#0079FF" android:width="1dp"/>            <solid android:color="#0079FF"/>            <corners android:topLeftRadius="0dp" android:bottomLeftRadius="0dp" android:topRightRadius="3dp" android:bottomRightRadius="3dp"/>        </shape>    </item>    <item>        <shape >            <stroke android:color="#0079FF" android:width="1dp"/>            <solid android:color="#FFFFFF"/>            <corners android:topLeftRadius="0dp" android:bottomLeftRadius="0dp" android:topRightRadius="3dp" android:bottomRightRadius="3dp"/>        </shape>    </item></selector>

res/drawable/seg_text_color_selector.xml

<?xml version="1.0" encoding="utf-8"?><selector xmlns:android="http://schemas.android.com/apk/res/android" >    <item android:state_selected="true" android:color="#FFFFFF"/>	<item android:color="#0079FF"/></selector>

这几个是对选中状态进行设置。

下面对LinearLayout进行改造~~~

其实就是放两个TextView。

SegmentView.java

package cn.haiwan.app.widget;import org.xmlpull.v1.XmlPullParser;import android.R.integer;import android.content.Context;import android.content.res.ColorStateList;import android.util.AttributeSet;import android.util.TypedValue;import android.view.Gravity;import android.view.View;import android.widget.LinearLayout;import android.widget.TextView;import cn.haiwan.R;public class SegmentView extends LinearLayout {	private TextView textView1;	private TextView textView2;	private onSegmentViewClickListener listener;	public SegmentView(Context context, AttributeSet attrs) {		super(context, attrs);		init();	}		public SegmentView(Context context) {		super(context);		init();	}	private void init() {//		this.setLayoutParams(new LinearLayout.LayoutParams(dp2Px(getContext(), 60), LinearLayout.LayoutParams.WRAP_CONTENT));		textView1 = new TextView(getContext());		textView2 = new TextView(getContext());		textView1.setLayoutParams(new LayoutParams(0, LayoutParams.WRAP_CONTENT, 1));		textView2.setLayoutParams(new LayoutParams(0, LayoutParams.WRAP_CONTENT, 1));		textView1.setText("SEG1");		textView2.setText("SEG2");		XmlPullParser xrp = getResources().getXml(R.drawable.seg_text_color_selector);  	    try {  	        ColorStateList csl = ColorStateList.createFromXml(getResources(), xrp);  	        textView1.setTextColor(csl);	        textView2.setTextColor(csl);	      } catch (Exception e) {  	    } 	    textView1.setGravity(Gravity.CENTER);	    textView2.setGravity(Gravity.CENTER);	    textView1.setPadding(3, 6, 3, 6);	    textView2.setPadding(3, 6, 3, 6);	    setSegmentTextSize(16);		textView1.setBackgroundResource(R.drawable.seg_left);		textView2.setBackgroundResource(R.drawable.seg_right);		textView1.setSelected(true);		this.removeAllViews();		this.addView(textView1);		this.addView(textView2);		this.invalidate();				textView1.setOnClickListener(new OnClickListener() {						@Override			public void onClick(View v) {				if (textView1.isSelected()) {					return;				}				textView1.setSelected(true);				textView2.setSelected(false);				if (listener != null) {					listener.onSegmentViewClick(textView1, 0);				}			}		});		textView2.setOnClickListener(new OnClickListener() {						@Override			public void onClick(View v) {				if (textView2.isSelected()) {					return;				}				textView2.setSelected(true);				textView1.setSelected(false);				if (listener != null) {					listener.onSegmentViewClick(textView2, 1);				}			}		});	}	/**	 * 设置字体大小 单位dip	 * <p>2014年7月18日</p>	 * @param dp	 * @author RANDY.ZHANG	 */	public void setSegmentTextSize(int dp) {		textView1.setTextSize(TypedValue.COMPLEX_UNIT_DIP, dp);		textView2.setTextSize(TypedValue.COMPLEX_UNIT_DIP, dp);	}		private static int dp2Px(Context context, float dp) {		final float scale = context.getResources().getDisplayMetrics().density;		return (int) (dp * scale + 0.5f);	}		public void setOnSegmentViewClickListener(onSegmentViewClickListener listener) {		this.listener = listener;	}			/**	 * 设置文字	 * <p>2014年7月18日</p>	 * @param text	 * @param position	 * @author RANDY.ZHANG	 */	public void setSegmentText(CharSequence text,int position) {		if (position == 0) {			textView1.setText(text);		}		if (position == 1) {			textView2.setText(text);		}	}		public static interface onSegmentViewClickListener{		/**		 * 		 * <p>2014年7月18日</p>		 * @param v		 * @param position 0-左边 1-右边		 * @author RANDY.ZHANG		 */		public void onSegmentViewClick(View v,int position);	}}

<?xml version="1.0" encoding="utf-8"?><LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"    android:layout_width="match_parent"    android:layout_height="match_parent"    android:orientation="vertical" >   	<cn.haiwan.app.widget.SegmentView 	    android:layout_width="160dp"	    android:layout_height="wrap_content"	    android:layout_gravity="center_horizontal"	    /></LinearLayout>
