效果图
拖动,惯性,自动补正效果
隐藏刻度线,更改背景图,设置总刻度效果(注:图中总刻度为12,不是60,所以松手时,指针补正至5点)
一 引用方法
1.在root build.gradle中加入
allprojects {repositories {...maven { url 'https://jitpack.io' }}}2.在项目的 build.gradle中加入
dependencies { implementation 'com.github.oneAcorn:WeightDialView-master:1.0.2'}二 使用方法
1.在xml中声明,total_scale为总刻度
<view android:id="@+id/weightdialview" class="com.acorn.weightdiallibrary.WeightDialView" android:layout_width="300dp" android:layout_height="300dp" app:total_scale="100" />2.设置初始相关参数
weightDialView.setCircle(10); //设置当前圈数为10 weightDialView.setScale(7); //设置当前指向刻度为73.增加/减少总刻度
//增加总刻度 public void addTotalScale(View view) { weightDialView.setTotalScale(weightDialView.getTotalScale() + 10); } //减少总刻度 public void reduceTotalScale(View view) { try { weightDialView.setTotalScale(weightDialView.getTotalScale() - 10); } catch (Exception e) { //总刻度不能小于0 Toast.makeText(this, e.getMessage(), Toast.LENGTH_LONG).show(); } }4.增加/减少指针与圆心的距离比
//增加指针与圆心的距离比 public void addThumbDistance(View view) { try { //0~1,越小越靠近边缘,越大越靠近圆心 weightDialView.setThumbDistance(weightDialView.getThumbDistance() - 0.05f); } catch (Exception e) { //distance必须大于等于0或小于等于1 Toast.makeText(this, e.getMessage(), Toast.LENGTH_LONG).show(); } notifyStatus(); } //减少指针与圆心的距离比 public void reduceThumbDistance(View view) { try { //0~1,越小越靠近边缘,越大越靠近圆心 weightDialView.setThumbDistance(weightDialView.getThumbDistance() + 0.05f); } catch (Exception e) { //distance必须大于等于0或小于等于1 Toast.makeText(this, e.getMessage(), Toast.LENGTH_LONG).show(); } notifyStatus(); }5.显示/隐藏刻度线,显示/隐藏背景图
weightDialView.showScaleLine(); //显示刻度线weightDialView.hideScaleLine(); //隐藏刻度线 private boolean flag = false; public void toggleBackground(View view) { if (flag) { weightDialView.setCircleBackground(null); //隐藏背景图 } else { //显示背景图 weightDialView.setCircleBackground(ImageUtil .drawableToBitamp(getResources() .getDrawable(R.mipmap.watch_dial))); //设置总刻度12 weightDialView.setTotalScale(12); } bgBtn.setText(flag ? "显示背景图" : "隐藏背景图"); flag = !flag; }6.设置监听器
weightDialView.setOnScaleChangeListener(new WeightDialView.OnScaleChangeListener() { @Override public void onScaleChange(int newScale, boolean isClockwise, int circles) { listenerTv.setText("当前刻度:" + newScale + ",圈数:" + circles + ",顺时针:" + isClockwise); } });项目地址
