使用

Gradle ​

修改项目 build.gradle，增加下面代码:

    dependencies {
        compile 'com.ayst.dbv:dashboardview:1.5.1'
    }

Java

    public class MainActivity extends AppCompatActivity {
    
        private DashboardView mDashboardView;
    
        @Override
        protected void onCreate(Bundle savedInstanceState) {
            super.onCreate(savedInstanceState);
            setContentView(R.layout.activity_main);
    
            mDashboardView = (DashboardView) findViewById(R.id.dashboardview_1);
            mDashboardView.setValue(50); // Set value
            mDashboardView.resetValue(50); // Set value and clear maximum and minimum
        }
    }

XML

如果决定使用DashboardView作为视图，则可以在xml布局中定义它，如下所示：

   <com.ayst.dashboardview.DashboardView
       android:id="@+id/dashboardview_1"
       android:layout_width="300dp"
       android:layout_height="wrap_content"
       app:dbv_firstColor="@color/red"
       app:dbv_secondColor="@color/yellow"
       app:dbv_thirdColor="@color/green"
       app:dbv_max="0"
       app:dbv_min="-100"
       app:dbv_section="10"
       app:dbv_portion="10"
       app:dbv_lineWidth="2dp"
       app:dbv_colorWidth="10dp"
       app:dbv_colorPadding="10dp"
       app:dbv_longScaleLength="15dp"
       app:dbv_shortScaleLength="10dp"
       app:dbv_startAngle="180"
       app:dbv_sweepAngle="180"
       app:dbv_value="-30"
       app:dbv_showValueText="false"
       app:dbv_showPointerRange="true"
       app:dbv_firstRange="30"
       app:dbv_secondRange="20"
       app:dbv_headerText="dbm"
       app:dbv_headerTextColor="@color/white"
       app:dbv_pointerColor="@color/white"
       app:dbv_minPointerColor="@color/white_30"
       app:dbv_maxPointerColor="@color/white_30"
       app:dbv_scaleColor="@color/white"
       app:dbv_scaleTextSize="12sp"
       />
