2015.7.30更新： 最近尝试了多种方法，终于把该lib上传到Jcenter了，使用Android studio的用户，，直接在Build.Gradle中添加如下一行代码，即可以引用该库（有空的话，我会把我的方法写下来）
compile ‘cn.weidongjian.android:progress-button:0.2’
这是一个带progressBar的Button，用于告诉用户正在处理数据和反馈处理结果，支付宝最新版本也有用到这个效果的按钮，请看效果图：
使用方法（针对Android studio）在项目的build.gradle中添加如下代码dependencies {compile ‘cn.weidongjian.android:progress-button:0.2’}
2 在xml中引用该控件：
<cnandroid:layout_width=”wrap_content”android:layout_height=”wrap_content”android:text=”New Button”android:paddingLeft=”30dp”android:paddingRight=”30dp”android:textColor=”@android:color/white”android:textSize=”16sp”android:background=”@drawable/selector_button”android:id=”@+id/button”android:layout_centerVertical=”true”android:layout_centerHorizontal=”true”/>
4 在activity中设置各种效果：
private ProgressButton button;button = (ProgressButton) findViewById(R.id.button);button.startRotate();\\添加并开始旋转progressBarbutton.animError();\\显示错误符号button.animFinish();\\显示正确符号button.removeDrawable();\\移除progressBar代码说明实现方法：自定义一个drawable，然后通过textview的setCompoundDrawablesWithIntrinsicBounds的方法添加该drawable到Button中，因为Button是Extend Textview的drawable = new ProgressDrawable(getTextSize(), this);this.setCompoundDrawablesWithIntrinsicBounds(drawable, null, null, null);自定义一个drawable，并且实现旋转，打钩，打叉的效果{private Paint mPaint;private float width;STAGE_NULL = 0, STAGE_ROTATE = 1, STAGE_FINISH = 2, STAGE_ERROR = 3;private int stage = 0;private RectF rectF;private float centerX, centerY;private float degreen = 0;private ValueAnimator animator;private Path pathFinish, pathErrorOne, pathErrorTwo;private float lenFinish, lenError, length;private int colorDefault = Color.WHITE, colorError = Color.RED;private Button button;private Animatable animatable;public ProgressDrawable(float size, Button button) {this.width = size;this.button = button;mPaint = new Paint(Paint.ANTI_ALIAS_FLAG);mPaint.setStyle(Paint.Style.STROKE);mPaint.setStrokeWidth(4);rectF = new RectF(0, 0, width, width);centerX = width/2;centerY = width/2;initPath();}() {pathFinish = new Path();pathFinish.moveTo(width * 1f, width * 0.2f);pathFinish.lineTo(width * 0.4f, width * 0.8f);pathFinish.lineTo(0f, width * 0.4f);PathMeasure pm = new PathMeasure(pathFinish, false);lenFinish = pm.getLength();pathErrorOne = new Path();pathErrorOne.moveTo(width * 0.9f, width * 0.9f);pathErrorOne.lineTo(width * 0.1f, width * 0.1f);pm.setPath(pathErrorOne, false);lenError = pm.getLength();pathErrorTwo = new Path();pathErrorTwo.moveTo(width * 0.9f, width * 0.1f);pathErrorTwo.lineTo(width * 0.1f, width * 0.9f);}() {return (int) width;}() {return (int) width;}(Canvas canvas) {if (stage == STAGE_NULL)return;if (stage == STAGE_ROTATE) {canvas.save();canvas.rotate(degreen, centerX, centerY);canvas.drawArc(rectF, -90f, 100f, false, mPaint);canvas.restore();return;}if (stage == STAGE_FINISH) {canvas.drawPath(pathFinish, mPaint);mPaint.setPathEffect(null);return;}if (stage == STAGE_ERROR) {canvas.drawPath(pathErrorOne, mPaint);canvas.drawPath(pathErrorTwo, mPaint);mPaint.setPathEffect(null);return;}}(int alpha) {mPaint.setAlpha(alpha);}(ColorFilter cf) {mPaint.setColorFilter(cf);}() {return PixelFormat.TRANSLUCENT;}() {stage = STAGE_ROTATE;mPaint.setColor(colorDefault);button.setClickable(false);if (animator == null) {animator = ValueAnimator.ofFloat(0f, 1f);animator.setDuration(2000);animator.setRepeatCount(ValueAnimator.INFINITE);animator.setRepeatMode(ValueAnimator.RESTART);animator.addUpdateListener(new ValueAnimator.AnimatorUpdateListener() {(ValueAnimator animation) {degreen += 5;invalidateSelf();}});}animator.start();}() {if (animator != null && animator.isRunning()) {animator.end();}}(float phase) {mPaint.setPathEffect(new DashPathEffect(new float[]{length, length}, -length * phase));invalidateSelf();}() {stage = STAGE_FINISH;length = lenFinish;mPaint.setColor(colorDefault);startAnim();}() {stage = STAGE_ERROR;length = lenError;mPaint.setColor(colorError);startAnim();}() {stopRotate();ObjectAnimator animator = ObjectAnimator.ofFloat(this, “Phase”, 1f, 0f);animator.setDuration(400);animator.setInterpolator(new AccelerateInterpolator());animator.addListener(new AnimatorListenerAdapter() {(Animator animation) {button.setClickable(true);if (animatable != null){animatable.stop();}}});animator.start();}(int color) {this.colorDefault = color;}(Animatable animatable) {this.animatable = animatable;}}自己打败自己是最可悲的失败，
