这是MPAndroidChart库更改后的实际解决方案2017 。
1。添加到build.gradle
allprojects {
repositories {
maven { url "https://jitpack.io" }
}
}
以及您的app build.gradle
dependencies {
compile 'com.github.PhilJay:MPAndroidChart:v3.0.2'
}
2。将图表元素添加到模板中:
<com.github.mikephil.charting.charts.HorizontalBarChart
android:id="@+id/chart"
android:layout_width="match_parent"
android:layout_height="match_parent" />
3。添加到片段onCreateView(或Activity onCreate)
HorizontalBarChart chart = (HorizontalBarChart) view.findViewById(R.id.chart);
BarDataSet set1;
set1 = new BarDataSet(getDataSet(), "The year 2017");
set1.setColors(Color.parseColor("#F78B5D"), Color.parseColor("#FCB232"), Color.parseColor("#FDD930"), Color.parseColor("#ADD137"), Color.parseColor("#A0C25A"));
ArrayList<IBarDataSet> dataSets = new ArrayList<IBarDataSet>();
dataSets.add(set1);
BarData data = new BarData(dataSets);
// hide Y-axis
YAxis left = chart.getAxisLeft();
left.setDrawLabels(false);
// custom X-axis labels
String[] values = new String[] { "1 star", "2 stars", "3 stars", "4 stars", "5 stars"};
XAxis xAxis = chart.getXAxis();
xAxis.setValueFormatter(new MyXAxisValueFormatter(values));
chart.setData(data);
// custom description
Description description = new Description();
description.setText("Rating");
chart.setDescription(description);
// hide legend
chart.getLegend().setEnabled(false);
chart.animateY(1000);
chart.invalidate();
4。最后使用图表将一些自定义类和函数添加到Fragment \ Activity:
public class MyXAxisValueFormatter implements IAxisValueFormatter {
private String[] mValues;
public MyXAxisValueFormatter(String[] values) {
this.mValues = values;
}
@Override
public String getFormattedValue(float value, AxisBase axis) {
return mValues[(int) value];
}
}
private ArrayList<BarEntry> getDataSet() {
ArrayList<BarEntry> valueSet1 = new ArrayList<>();
BarEntry v1e2 = new BarEntry(1, 4341f);
valueSet1.add(v1e2);
BarEntry v1e3 = new BarEntry(2, 3121f);
valueSet1.add(v1e3);
BarEntry v1e4 = new BarEntry(3, 5521f);
valueSet1.add(v1e4);
BarEntry v1e5 = new BarEntry(4, 10421f);
valueSet1.add(v1e5);
BarEntry v1e6 = new BarEntry(5, 27934f);
valueSet1.add(v1e6);
return valueSet1;
}

由于我无法评论Aida Drogan解决方案,因此将其发布为另一个答案:
为了将标签限制为5个并且不重叠,请看一下此函数: 限制间隔 如果您使用的是基于数组索引的格式化程序(如上),则可以将轴的最小间隔限制为“ 1”:
ost << *x.first << // more code
这将防止格式化程序绘制重复的轴标签(由轴间隔<1引起)。一旦图表的“缩放级别”足够高,它将停止重新计算较小的间隔。

2019解决方案:这是一个库,可以完全满足您的需求,而没有任何麻烦:
在存储库末尾的root build.gradle中:
allprojects {
repositories {
...
maven { url 'https://jitpack.io' }
}
}
在您的应用程序build.gradle中:
implementation 'com.github.Inconnu08:android-ratingreviews:1.0.0'
java
RatingReviews ratingReviews = (RatingReviews) findViewById(R.id.rating_reviews);
int colors[] = new int[]{
Color.parseColor("#0e9d58"),
Color.parseColor("#bfd047"),
Color.parseColor("#ffc105"),
Color.parseColor("#ef7e14"),
Color.parseColor("#d36259")};
int raters[] = new int[]{
new Random().nextInt(100),
new Random().nextInt(100),
new Random().nextInt(100),
new Random().nextInt(100),
new Random().nextInt(100)
};
ratingReviews.createRatingBars(100, BarLabels.STYPE1, colors, raters);
xml
<com.taufiqrahman.reviewratings.RatingReviews
xmlns:bar="http://schemas.android.com/apk/res-auto"
android:id="@+id/rating_reviews"
android:layout_width="0dp"
android:layout_height="wrap_content"
android:layout_marginStart="42dp"
android:layout_marginTop="8dp"
android:layout_marginBottom="8dp"
app:layout_constraintBottom_toBottomOf="parent"
app:layout_constraintEnd_toEndOf="parent"
app:layout_constraintStart_toEndOf="@+id/textView"
app:layout_constraintTop_toTopOf="parent"
app:layout_constraintVertical_bias="0.499"
bar:animation="true"
bar:max_value="100"
bar:show_label="true"
bar:spaces="0dp"
bar:text_color="#333333"
