DecoView的使用

DecoView是一款专为Android平台设计的动画圆形图表库,能让你轻松打造出类似Google Fit那样的炫酷圆环视图.它的自定义选项很丰富,无论是数据序列(SeriesItem)还是动画事件(DecoEvent),从颜色到线条粗细都能精细配置.而且直接写在XML布局里就行,代码调用也很简单,做些健身,智能家居之类的App时用来展示进度或实时数据,效果会非常直观生动.

1. 引入DecoView的库

在Android项目的build.gradle(Module :app)中添加,然后在Sync.

implementation 'com.github.bmarrdev:android-DecoView-charting:v1.2'

如果出现下面的错误:

Duplicate class android.support.v4.app.INotificationSideChannel found in modules core-1.7.0-runtime (androidx.core:core:1.7.0) and support-v4-23.3.0-runtime (com.android.support:support-v4:23.3.0)

Go to the documentation to learn how to Fix dependency resolution errors.

这个问题的核心是项目的依赖项中同时混用了老旧的Android Support库和现代的AndroidX库,而你的项目本身很可能已经迁移到了AndroidX.Android官方已经停止维护Support库,并推荐所有项目迁移到AndroidX.因此,唯一的解决方案是彻底清理项目中的Support库依赖.解决这个问题的唯一方法是彻底清除项目中对Support库的依赖.在gradle.properties文件中添加:

# 启用AndroidX库
android.useAndroidX=true
# 启用Jetifier,将第三方库中的Support库自动转换为AndroidX
android.enableJetifier=true

2. 在项目中添加如下的布局文件cardview_deco.xml:

3. MainActivity.java文件:

import android.widget.TextView;

import com.hookedonplay.decoviewlib.DecoView;
import com.hookedonplay.decoviewlib.charts.SeriesItem;
import com.hookedonplay.decoviewlib.events.DecoEvent;

public class MainActivity extends AppCompatActivity {

    private LinearLayout cardViewContainer;
    private TextView txtDays;
    private DecoView decoView;
    private SeriesItem redSeries;
    private int redSeriesIndex;
    private int currentAngle = 0;
    private Handler timerHandler;
    private Runnable timerRunnable;
    private boolean clicked = true;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);

        cardViewContainer = findViewById(R.id.container_deco);
        LayoutInflater inflater = LayoutInflater.from(this);
        View view = inflater.inflate(R.layout.cardview_deco, cardViewContainer, false);
        cardViewContainer.addView(view);
        txtDays = view.findViewById(R.id.txt_day);
        initDecoView();

        txtDays.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View view) {
                int newProgress = currentAngle + 5;

                if (newProgress > 100) {
                    newProgress = 100;
                }

                DecoEvent event = new DecoEvent.Builder(newProgress)
                        .setIndex(redSeriesIndex)                   
                        .setDuration(500)                          
                        .build();
                decoView.addEvent(event);

                currentAngle = newProgress;
                clicked = !clicked;
                if (clicked) {
                    txtDays.setText("Clicked!");

                else {
                    txtDays.setText("Clicked again!");
                }
            }
        });

    }

    private void initDecoView() {
        decoView = findViewById(R.id.pie_chart_time2);
        decoView.configureAngles(360, 0); 

        // 创建灰色背景
        SeriesItem backgroundSeries = new SeriesItem.Builder(Color.GRAY)
                .setRange(0, 100, 100)
                .setLineWidth(40f)
                .build();
        decoView.addSeries(backgroundSeries);

        SeriesItem redSeries = new SeriesItem.Builder(Color.RED)
                .setRange(0, 100, 0) 
                .setLineWidth(40f)
                .build();
        redSeriesIndex = decoView.addSeries(redSeries);

        startAngleIncrease();
    }

    private void startAngleIncrease() {
        timerHandler = new Handler(Looper.getMainLooper());
        timerRunnable = new Runnable() {
            @Override
            public void run() {
                currentAngle = (currentAngle + 1) % 360;

                DecoEvent event = new DecoEvent.Builder(currentAngle)
                        .setIndex(redSeriesIndex)
                        .setDuration(500)
                        .build();
                decoView.addEvent(event);

                timerHandler.postDelayed(this, 1000);
            }
        };
        timerHandler.post(timerRunnable);
    }
}

上面的代码实现了下面的功能:绘制底色为灰色的红色圆环,点击一下圆环中间的文本,红色圆环增加5°,每秒钟红色圆环增加1°.
