本文实例为大家分享了Android QQ运动步数的具体代码，供大家参考，具体内容如下

今天我们实现下面这样的效果：

首先自定义属性：

自定义View代码如下：

/**

public class MyQQStep extends View {

private int out_color;

private int inner_color;

private float width;

private float textSize;

private int color;

private int width01;

private int height01;

private Paint outPaint;

private Paint innerPaint;

private Paint textPaint;

private float percent;

private int step;

public MyQQStep(Context context) {

this(context,null);

}

public MyQQStep(Context context, @Nullable AttributeSet attrs) {

this(context, attrs,0);

}

public MyQQStep(Context context, @Nullable AttributeSet attrs, int defStyleAttr) {

super(context, attrs, defStyleAttr);

TypedArray array = context.obtainStyledAttributes(attrs,R.styleable.MyQQStep);

out_color = array.getColor(R.styleable.MyQQStep_out_color, Color.BLACK);

inner_color = array.getColor(R.styleable.MyQQStep_inner_color, Color.RED);

width = array.getDimension(R.styleable.MyQQStep_border_width,10);

textSize = array.getDimensionPixelSize(R.styleable.MyQQStep_text_size,20);

color = array.getColor(R.styleable.MyQQStep_text_color, Color.GREEN);

array.recycle();

initPaint();

percent = 0;

step = 5000;

}

private void initPaint() {

outPaint = new Paint();

outPaint.setAntiAlias(true);

outPaint.setStyle(Paint.Style.STROKE);

outPaint.setStrokeWidth(width);

outPaint.setColor(out_color);

outPaint.setStrokeCap(Paint.Cap.ROUND);

innerPaint = new Paint();

innerPaint.setAntiAlias(true);

innerPaint.setStrokeWidth(width);

innerPaint.setStyle(Paint.Style.STROKE);

innerPaint.setColor(inner_color);

innerPaint.setStrokeCap(Paint.Cap.ROUND);

textPaint = new Paint();

textPaint.setAntiAlias(true);

textPaint.setColor(color);

textPaint.setStyle(Paint.Style.STROKE);

textPaint.setTextSize(textSize);

}

@Override

protected void onMeasure(int widthMeasureSpec, int heightMeasureSpec) {

//super.onMeasure(widthMeasureSpec, heightMeasureSpec);

int widthMode = MeasureSpec.getMode(widthMeasureSpec);

int heightMode = MeasureSpec.getMode(heightMeasureSpec);

if (widthMode == MeasureSpec.AT_MOST){

}else{

width01 = MeasureSpec.getSize(widthMeasureSpec);

}

if (heightMode == MeasureSpec.AT_MOST){

}else{

height01 = MeasureSpec.getSize(heightMeasureSpec);

}

setMeasuredDimension((width01>height01?height01:width01)

,(width01>height01?height01:width01));

}

@Override

protected void onDraw(Canvas canvas) {

super.onDraw(canvas);

int realWidth = getWidth()>getHeight()?getHeight():getWidth();

int realHeight = getWidth()>getHeight()?getHeight():getWidth();

RectF r1 = new RectF(width/2,width/2,realWidth-width/2

,realHeight-width/2);

canvas.drawArc(r1,135,270,false,outPaint);

canvas.drawArc(r1,135,270*percent,false,innerPaint);

Rect r = new Rect();

String s = step+"";

textPaint.getTextBounds(s,0,s.length(),r);

int textWidth = r.width();

int textHeight = r.height();

Paint.FontMetricsInt fontMetricsInt = new Paint.FontMetricsInt();

int dy = (fontMetricsInt.bottom-fontMetricsInt.top)/2-fontMetricsInt.bottom;

int baseLine = textHeight/2+dy+realHeight/2-textHeight/2;

int x0 = realWidth/2-textWidth/2;

canvas.drawText(s,x0,baseLine,textPaint);

}

public void setPercent(float percent,float value){

this.percent = percent;

this.step = (int) value;

invalidate();

}

}

最后在布局以及MainActivity中调用：

android:id="@+id/qq_step"

android:layout_width="match_parent"

android:layout_height="match_parent"

app:out_color="@color/colorAccent"

app:border_width="10dp"

app:inner_color="@color/colorPrimary"

app:text_size="20sp"

app:text_color="@color/colorPrimaryDark"

/>

private void initView() {

final MyQQStep qq_view = findViewById(R.id.qq_step);

ValueAnimator animator = ValueAnimator.ofFloat(0,5000);

animator.addUpdateListener(new ValueAnimator.AnimatorUpdateListener() {

@Override

public void onAnimationUpdate(ValueAnimator animation) {

float p = animation.getAnimatedFraction();

qq_view.setPercent(p,5000*p);

}

});

animator.setDuration(10000);

animator.start();

}
