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>res/drawable/seg_right.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="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>字体颜色：
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() {@Overridepublic 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() {@Overridepublic 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);}} 布局文件引用
<?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>
