android 支付动画效果

最近研究了一些动画效果这里就分享给大家吧 gif效果不太好因为压缩了一下凑合看看哈哈

20181106164205.gif

1.布局中有两个自定义类（外围整体用相对布局就能看到效果）

<Button
    android:id="@+id/button"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content" />
<com.simple.m.simpleandroid.MySquare
    android:id="@+id/sqareProcess"
    android:layout_width="150dip"
    android:layout_marginTop="100dp"
    android:layout_height="100dip"
    android:layout_centerHorizontal="true"
    app:currentPogress="0"
    app:progressColor="#c1d1dd"
    app:strokeColor="@color/lande"
    app:strokeWith="2dip"
    app:textColor="@color/lande"
    app:textSize="15sp" />
<com.simple.m.simpleandroid.Yuan
    android:layout_below="@+id/sqareProcess"
    android:id="@+id/yuan"
    android:visibility="gone"

    android:layout_width="50dip"

    android:layout_height="50dip"
    android:layout_centerHorizontal="true"
  />

2.画线类

public class MySquare extends View {

private static final float PER_LINE_MAX_Top = 40;
private static final float PER_LINE_MAX_Rit = 20;


private Context mContext;
private Paint paint;
private Paint processPaint;
private Paint textPaint;
private Canvas canvas;

private int currentPogress;
private int strokeColor = Color.BLACK;
private float strokeWith = 2.0f;
private int progressColor = Color.RED;
private int textColor = Color.BLUE;
private float textSize = 10.0f;

public MySquare(Context context, @Nullable AttributeSet attrs) {
    super(context, attrs);
    mContext = context;
    initValue(attrs);
}


private void initValue(AttributeSet attrs) {
    TypedArray typedArray = mContext.obtainStyledAttributes(attrs, R.styleable.SquareProcessView);
    currentPogress = typedArray.getInteger(R.styleable.SquareProcessView_currentPogress, 0);
    strokeColor = typedArray.getColor(R.styleable.SquareProcessView_strokeColor, ContextCompat.getColor(mContext, R.color.colorPrimary));
    strokeWith = typedArray.getDimension(R.styleable.SquareProcessView_strokeWith, strokeWith);
    progressColor = typedArray.getColor(R.styleable.SquareProcessView_progressColor, ContextCompat.getColor(mContext, R.color.colorAccent));
    textColor = typedArray.getColor(R.styleable.SquareProcessView_textColor, ContextCompat.getColor(mContext, R.color.colorAccent));
    textSize = typedArray.getDimension(R.styleable.SquareProcessView_textSize, textSize);
    initPaints();
}

private void initPaints() {
    paint = new Paint();
    paint.setColor(strokeColor);
    paint.setStrokeWidth(strokeWith);
    paint.setAntiAlias(true);
    paint.setStyle(Paint.Style.STROKE);
    initProcessPaint();
    initTextPaint();
}

private void initProcessPaint() {
    processPaint = new Paint();
    processPaint.setColor(progressColor);
    processPaint.setStrokeWidth(strokeWith);
    processPaint.setAntiAlias(true);
    processPaint.setStyle(Paint.Style.STROKE);
}

private void initTextPaint() {
    textPaint = new Paint();
    textPaint.setColor(textColor);
    textPaint.setAntiAlias(true);
    textPaint.setStyle(Paint.Style.STROKE);
    textPaint.setTextSize(textSize);

}

public void setCurrentPogress(int currentPogress) {
    this.currentPogress = currentPogress;
    invalidate();
}

@Override
protected void onDraw(Canvas canvas) {
    super.onDraw(canvas);
    this.canvas = canvas;
    /*画图*/
    drawSquare();
    /*画圆*/
    drawrec();

        /*画线*/
    drawProcessSquare(currentPogress);

}

private void drawrec() {
    Paint mPaint = new Paint();
    mPaint.setAntiAlias(true);
    mPaint.setStrokeWidth(strokeWith);

    mPaint.setColor(Color.rgb(79,80,101));
    canvas.drawCircle(canvas.getWidth() / 2, 10, 10, mPaint);
}

/**
 * 画线
 */
private void drawSquare() {
    drawRightLine();

}


private void drawRightLine() {
    Path path = new Path();
    /*把坐标移动到右上角*/
    path.moveTo(canvas.getWidth() / 2, 20);
    path.lineTo(canvas.getWidth() / 2, canvas.getHeight()-20);
    canvas.drawPath(path, paint);
}


/**
 * 画进度
 */
private void drawProcessSquare(int progress) {

    float rightProcess = 0;

    rightProcess = progress ;

    drawProgressRightLine(rightProcess);

}


private void drawProgressRightLine(float progress) {
    Path path = new Path();
    /*把坐标移动到右上角*/
    path.moveTo(canvas.getWidth() / 2, 20);
    path.lineTo(canvas.getWidth() / 2, canvas.getHeight() / PER_LINE_MAX_Rit * progress);
    canvas.drawPath(path, processPaint);
}


}

3.画圆类

public class Yuan extends View {


/**
 * view的宽度
 */
private int width;
/**
 * view的高度
 */
private int height;
/**
 * 圆角半径
 */
private int circleAngle;
/**
 * 默认两圆圆心之间的距离=需要移动的距离
 */
private int default_two_circle_distance;
/**
 * 两圆圆心之间的距离
 */
private int two_circle_distance;
/**
 * 背景颜色
 */
private int bg_color = 0xffbc7d53;
/**
 * 按钮文字字符串
 */
private String buttonString = "确认完成";
/**
 * 动画执行时间
 */
private int duration = 1000;
/**
 * view向上移动距离
 */
private int move_distance = 300;

/**
 * 圆角矩形画笔
 */
private Paint paint;
/**
 * 文字画笔
 */
private Paint textPaint;
/**
 * 对勾（√）画笔
 */
private Paint okPaint;
/**
 * 文字绘制所在矩形
 */
private Rect textRect = new Rect();

/**
 * 动画集
 */
private AnimatorSet animatorSet = new AnimatorSet();


/**
 * 绘制对勾（√）的动画
 */
private ValueAnimator animator_draw_ok;

/**
 * 是否开始绘制对勾
 */
private boolean startDrawOk = false;


/**
 * 根据view的大小设置成矩形
 */
private RectF rectf = new RectF();

/**
 * 路径--用来获取对勾的路径
 */
private Path path = new Path();
/**
 * 取路径的长度
 */
private PathMeasure pathMeasure;
/**
 * 对路径处理实现绘制动画效果
 */
private PathEffect effect;
private Canvas canvas;


private float strokeWith = 2.0f;


public Yuan(Context context, @Nullable AttributeSet attrs) {
    super(context, attrs);
    initPaint();
}


@Override
protected void onDraw(Canvas canvas) {
    super.onDraw(canvas);
    this.canvas = canvas;

    /*画圆*/
    drawrec();
    canvas.drawPath(path, okPaint);


}

private void drawrec() {
    Paint mPaint = new Paint();
    mPaint.setAntiAlias(true);
    mPaint.setStrokeWidth(strokeWith);

    mPaint.setColor(Color.rgb(20, 164, 101));
    canvas.drawCircle(canvas.getWidth() / 2, 50, 50, mPaint);
}


/**
 * 初始化所有动画
 */
private void initAnimation() {

    set_draw_ok_animation();

    animatorSet
            .play(animator_draw_ok);


}


/**
 * 绘制对勾的动画
 */
private void set_draw_ok_animation() {
    animator_draw_ok = ValueAnimator.ofFloat(1, 0);
    animator_draw_ok.setDuration(duration);
    animator_draw_ok.addUpdateListener(new ValueAnimator.AnimatorUpdateListener() {
        @Override
        public void onAnimationUpdate(ValueAnimator animation) {
            startDrawOk = true;
            float value = (Float) animation.getAnimatedValue();

            effect = new DashPathEffect(new float[]{pathMeasure.getLength(), pathMeasure.getLength()}, value * pathMeasure.getLength());
            okPaint.setPathEffect(effect);
            invalidate();
        }
    });
}

private void initPaint() {


    okPaint = new Paint();
    okPaint.setStrokeWidth(10);
    okPaint.setStyle(Paint.Style.STROKE);
    okPaint.setAntiAlias(true);
    okPaint.setColor(Color.WHITE);
}

@Override
protected void onSizeChanged(int w, int h, int oldw, int oldh) {
    super.onSizeChanged(w, h, oldw, oldh);

    width = w;
    height = h;

    default_two_circle_distance = (w - h) / 2;

    initOk();
    initAnimation();
    start();

}


/**
 * 绘制对勾
 */
private void initOk() {
    //对勾的路径
    path.moveTo(default_two_circle_distance + height / 9 * 3, height / 9 * 3);
    path.lineTo(default_two_circle_distance + height / 2, height / 8 * 4);
    path.lineTo(default_two_circle_distance + height / 4 * 3, height / 4);

    pathMeasure = new PathMeasure(path, true);

}

/**
 * 启动动画
 */
public void start() {
    animatorSet.start();
}


 }

最后附上我们的activity中的代码大功告成

 public class Main2Activity extends AppCompatActivity {
 private MySquare squareProgressView;
 private MyHandnler myHandnler = new MyHandnler(this);
 private int currentProcess;
 private int currentProcessGou;
 public WeakReference<Main2Activity> weakReference;
 private Yuan yuan;
 Animation animation;
 Button button;

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main2);
    squareProgressView = (MySquare) findViewById(R.id.sqareProcess);

    animation = AnimationUtils.loadAnimation(this, R.anim.anim_small);

    yuan = (Yuan) findViewById(R.id.yuan);
    try {
        sleep(2000);

    } catch (InterruptedException e) {
        e.printStackTrace();
    }
    button= findViewById(R.id.button);
    button.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View v) {
            myHandnler.sendEmptyMessage(1);
        }
    });
}

class MyHandnler extends Handler {


    public MyHandnler(Main2Activity mainActivity) {
        weakReference = new WeakReference<>(mainActivity);
    }

    @Override
    public void handleMessage(Message msg) {
        super.handleMessage(msg);
        /*圈线*/
        if (msg.what == 1) {
            if (weakReference.get().currentProcess <= 100) {
                weakReference.get().currentProcess++;
                weakReference.get().squareProgressView.setCurrentPogress(weakReference.get().currentProcess);
                sendEmptyMessageDelayed(1, 0);
            }
            if (weakReference.get().currentProcess == 40) {
                yuan.setVisibility(View.VISIBLE);
                yuan.startAnimation(animation);
                sendEmptyMessageDelayed(3, 0);
            }


        }
    }
}

@Override
protected void onDestroy() {
    super.onDestroy();
    myHandnler.removeCallbacksAndMessages(null);
}
 }
