仪表盘，看到这个我无奈了，

老大说要用这个，网上找的他说都好难看

然后自己改额，改动第三方的源码，改了挺久最后出来了这个效果

最后看到效果发现改的值得了

MainActivity.java 代码

package com.example.testybp.activity;import com.example.testybp.R;import com.example.testybp.weight.DialChart05View;import android.app.Activity;import android.os.Bundle;import android.os.Handler;import android.view.View;import android.view.View.OnClickListener;import android.widget.Button;import android.widget.TextView;public class MainActivity extends Activity {DialChart05View chart = null;DialChart05View chart1 = null;private int count = 0;private TextView tv_value;private Handler mHandler = new Handler() {};@Overrideprotected void onCreate(Bundle savedInstanceState) {super.onCreate(savedInstanceState);setContentView(R.layout.fragment_main);chart = (DialChart05View) findViewById(R.id.circle_view1);chart1 = (DialChart05View) findViewById(R.id.circle_view2);tv_value=(TextView) findViewById(R.id.tv_ybp_value);// 清除指针chart.getDialChart().getPointer().setLength(0f);// 清除轴线chart1.getDialChart().clearPlotAxis();final Button button = (Button) findViewById(R.id.button1);button.setOnClickListener(new OnClickListener() {@Overridepublic void onClick(View v) {if (count >= 100) {count = 0;mHandler.post(mRunnable);} else {if (count == 0) {mHandler.post(mRunnable);}}}});}private Runnable mRunnable = new Runnable() {@Overridepublic void run() {if (count <= 100) {chart1.setCurrentStatus1((count) / 100f);chart1.invalidate();tv_value.setText(count+" M/S");count += 4;mHandler.postDelayed(mRunnable, 100);}}};}

Layout.xml 代码

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"    xmlns:tools="http://schemas.android.com/tools"    android:layout_width="match_parent"    android:layout_height="match_parent"    android:background="#ffffff"    android:orientation="vertical" >    <RelativeLayout        android:layout_width="match_parent"        android:layout_height="wrap_content" >        <com.example.testybp.weight.DialChart05View            android:id="@+id/circle_view1"            android:layout_width="260dip"            android:layout_height="260dip"            android:layout_centerHorizontal="true" />        <com.example.testybp.weight.DialChart05View            android:id="@+id/circle_view2"            android:layout_width="260dip"            android:layout_height="260dip"            android:layout_centerHorizontal="true" />        <LinearLayout            android:layout_width="wrap_content"            android:layout_height="wrap_content"            android:layout_centerInParent="true"            android:orientation="vertical" >            <TextView                android:id="@+id/tv_ybp_title"                android:layout_width="wrap_content"                android:layout_height="wrap_content"                android:layout_marginTop="120dp"                android:text="实时速度"                android:textColor="#000000"                android:textSize="14sp" />                        <TextView                android:id="@+id/tv_ybp_value"                android:layout_width="wrap_content"                android:layout_height="wrap_content"                android:layout_marginTop="4dp"                android:text="0 M/S"                android:textColor="#000000"                android:textSize="14sp" />        </LinearLayout>    </RelativeLayout>    <Button        android:id="@+id/button1"        android:layout_width="wrap_content"        android:layout_height="wrap_content"        android:layout_gravity="center_horizontal"        android:text="Random" /></LinearLayout>
