先给大家展示下效果图：

不知道大家对效果图感觉怎么样，个人觉还不错，感兴趣的朋友可以参考下实现代码哦。

public class ToggleButton extends View { private SpringSystem springSystem; private Spring spring ; /** */ private float radius; /** 开启颜色*/ private int onColor = Color.parseColor("#4ebb7f"); /** 关闭颜色*/ private int offBorderColor = Color.parseColor("#dadbda"); /** 灰色带颜色*/ private int offColor = Color.parseColor("#ffffff"); /** 手柄颜色*/ private int spotColor = Color.parseColor("#ffffff"); /** 边框颜色*/ private int borderColor = offBorderColor; /** 画笔*/ private Paint paint ; /** 开关状态*/ private boolean toggleOn = false; /** 边框大小*/ private int borderWidth = 2; /** 垂直中心*/ private float centerY; /** 按钮的开始和结束位置*/ private float startX, endX; /** 手柄X位置的最小和最大值*/ private float spotMinX, spotMaxX; /**手柄大小 */ private int spotSize ; /** 手柄X位置*/ private float spotX; /** 关闭时内部灰色带高度*/ private float offLineWidth; /** */ private RectF rect = new RectF(); /** 默认使用动画*/ private boolean defaultAnimate = true; /** 是否默认处于打开状态*/ private boolean isDefaultOn = false; private OnToggleChanged listener; private ToggleButton(Context context) { super(context); } public ToggleButton(Context context, AttributeSet attrs, int defStyleAttr) { super(context, attrs, defStyleAttr); setup(attrs); } public ToggleButton(Context context, AttributeSet attrs) { super(context, attrs); setup(attrs); } @Override protected void onDetachedFromWindow() { super.onDetachedFromWindow(); spring.removeListener(springListener); } public void onAttachedToWindow() { super.onAttachedToWindow(); spring.addListener(springListener); } public void setup(AttributeSet attrs) { paint = new Paint(Paint.ANTI_ALIAS_FLAG); paint.setStyle(Style.FILL); paint.setStrokeCap(Cap.ROUND); springSystem = SpringSystem.create(); spring = springSystem.createSpring(); spring.setSpringConfig(SpringConfig.fromOrigamiTensionAndFriction(50, 7)); this.setOnClickListener(new OnClickListener() { @Override public void onClick(View arg0) { toggle(defaultAnimate); } }); TypedArray typedArray = getContext().obtainStyledAttributes(attrs, R.styleable.ToggleButton); offBorderColor = typedArray.getColor(R.styleable.ToggleButton_tbOffBorderColor, offBorderColor); onColor = typedArray.getColor(R.styleable.ToggleButton_tbOnColor, onColor); spotColor = typedArray.getColor(R.styleable.ToggleButton_tbSpotColor, spotColor); offColor = typedArray.getColor(R.styleable.ToggleButton_tbOffColor, offColor); borderWidth = typedArray.getDimensionPixelSize(R.styleable.ToggleButton_tbBorderWidth, borderWidth); defaultAnimate = typedArray.getBoolean(R.styleable.ToggleButton_tbAnimate, defaultAnimate); isDefaultOn = typedArray.getBoolean(R.styleable.ToggleButton_tbAsDefaultOn, isDefaultOn); typedArray.recycle(); borderColor = offBorderColor; if (isDefaultOn) { toggleOn(); } } public void toggle() { toggle(true); } public void toggle(boolean animate) { toggleOn = !toggleOn; takeEffect(animate); if(listener != null){ listener.onToggle(toggleOn); } } public void toggleOn() { setToggleOn(); if(listener != null){ listener.onToggle(toggleOn); } } public void toggleOff() { setToggleOff(); if(listener != null){ listener.onToggle(toggleOn); } } /** * 设置显示成打开样式，不会触发toggle事件 */ public void setToggleOn() { setToggleOn(true); } /** * @param animate asd */ public void setToggleOn(boolean animate){ toggleOn = true; takeEffect(animate); } /** * 设置显示成关闭样式，不会触发toggle事件 */ public void setToggleOff() { setToggleOff(true); } public void setToggleOff(boolean animate) { toggleOn = false; takeEffect(animate); } private void takeEffect(boolean animate) { if(animate){ spring.setEndValue(toggleOn ?

别忘了自定义属性：attrs.xml

<"1.0" encoding="utf-8"?> <resources> <declare-styleable name="ToggleButton"> <attr name="tbBorderWidth" format="dimension"/> <attr name="tbOffBorderColor" format="reference|color"/> <attr name="tbOffColor" format="reference|color"/> <attr name="tbOnColor" format="reference|color"/> <attr name="tbSpotColor" format="reference|color"/> <attr name="tbAnimate" format="reference|boolean"/> <attr name="tbAsDefaultOn" format="reference|boolean"/> </declare-styleable> </resources>

main.xml

<"1.0" encoding="utf-8"?> <LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" xmlns:tools="http://schemas.android.com/tools" android:layout_width="match_parent" android:layout_height="match_parent" xmlns:toggle="http://schemas.android.com/apk/res-auto" android:orientation="vertical" > <LinearLayout android:layout_marginTop="10dp" android:layout_width="match_parent" android:gravity="center_horizontal" android:layout_height="wrap_content"> <com.example.ekikousei.view.ToggleButton android:id="@+id/mToggleButton01" android:layout_width="54dp" android:layout_height="30dp"> </com.example.ekikousei.view.ToggleButton> </LinearLayout> <LinearLayout android:layout_marginTop="10dp" android:layout_width="match_parent" android:gravity="center_horizontal" android:layout_height="wrap_content"> <com.example.ekikousei.view.ToggleButton android:id="@+id/mToggleButton02" android:layout_width="54dp" android:layout_height="30dp" toggle:tbBorderWidth="2dp" toggle:tbOffBorderColor="#000" toggle:tbOffColor="#ddd" toggle:tbOnColor="#f00" toggle:tbSpotColor="#00f"> </com.example.ekikousei.view.ToggleButton> </LinearLayout> </LinearLayout>

Maintivity

public class MainActivity extends Activity { private ToggleButton mToggleButton01; @Override protected void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.activity_main); mToggleButton01 = (ToggleButton) findViewById(R.id.mToggleButton01); mToggleButton01.setOnToggleChanged(new ToggleButton.OnToggleChanged() { @Override public void onToggle(boolean on) { if (on) { Toast.makeText(MainActivity.this, "打开", Toast.LENGTH_SHORT).show(); }else { Toast.makeText(MainActivity.this, "默认关闭", Toast.LENGTH_SHORT).show(); } } }); } }
