如何获取手机性能测试数据FPS

本人在做APP性能测试的过程中，为了测试APP在各个场景下的流畅度，需要收集手在各个运行场景下的fps数据，经常查资料，使用的是adb shell命令：

adb shell dumpsys gfxinfo com.happyjuzi.apps.juzi

分享代码，供大家参考。
测试方法：

Fps fps = new Fps();
fps.start();
//do something
fps.stopFps();
fps.join();

多线程类的代码：
package monkeytest;

import java.io.BufferedReader;
import java.io.IOException;
import java.io.InputStream;
import java.io.InputStreamReader;
import java.util.ArrayList;
import java.util.List;
import java.util.Random;
import java.util.regex.Matcher;
import java.util.regex.Pattern;
import source.AppLocalMySql;
import source.Common;

public class Fps extends Thread {
private boolean KEY = true;
private static String testName = "normal";
private int mark = Common.mark;

@Override
public void run() {
while (KEY) {
execCmdAdb("adb shell dumpsys gfxinfo com.happyjuzi.apps.juzi");
Common.getInstance().sleep(5000);
}
}

public int getMatcher(String text, Pattern pattern) {
Pattern newattern = Pattern.compile(pattern.toString().trim());
Matcher matcher = newattern.matcher(text);
List<String> numbers = new ArrayList<>();
while (matcher.find()) {
String number = matcher.group(0);
numbers.add(number);
}
double result = 0;
for (int i = 0; i < numbers.size(); i++) {
double num = Common.getInstance().changeStringToDouble(numbers.get(i));
result += num;
}
int total = (int) result + new Random().nextInt(2);
return total;
}

/**
* 结束线程
*/
public void stopFps() {
this.KEY = false;
}

/**
* 执行cmd命令
*
* @param cmd
* 命令
*/
public void execCmdAdb(String cmd) {
Pattern pattern = Pattern.compile(" ([0-9]{1,2}+\\.[0-9]{2})");
output("正在执行：" + cmd);
String OSname = System.getProperty("os.name");
try {
Process p = null;
if (OSname.contains("Mac")) {
p = Runtime.getRuntime().exec(Common.ADB_PATH + cmd);
} else {
p = Runtime.getRuntime().exec("cmd /c " + cmd);
}
// 正确输出流
InputStream input = p.getInputStream();// 创建并实例化输入字节流
BufferedReader reader = new BufferedReader(new InputStreamReader(input));// 先通过inputstreamreader进行流转化，在实例化bufferedreader，接收内容
String line = "";
while ((line = reader.readLine()) != null) {// 循环读取
if (line.startsWith(" ")) {
Matcher matcher = pattern.matcher(line);
if (matcher.find()) {
AppLocalMySql.getInstance().saveFps(testName, mark);
getMatcher(line, pattern);// 输出
}
}
}
reader.close();// 此处reader依赖于input，应先关闭
input.close();
// 错误输出流
InputStream errorInput = p.getErrorStream();// 创建并实例化输入字节流
BufferedReader errorReader = new BufferedReader(new InputStreamReader(errorInput));// 先通过inputstreamreader进行流转化，在实例化bufferedreader，接收内容
String eline = "";
while ((eline = errorReader.readLine()) != null) {// 循环读取
System.out.println(eline);// 输出
Common.getInstance().saveToFile(eline, "runlog.log");// 保存，false表示不覆盖
}
errorReader.close();// 此处有依赖关系，先关闭errorReader
errorInput.close();
} catch (IOException e) {
output("执行" + cmd + "失败！");
e.printStackTrace();
}
}

public void output(String text) {
System.out.println(text);
}

public void output(Object... object) {
if (object.length == 1) {
output(object[0].toString());
return;
}
for (int i = 0; i < object.length; i++) {
System.out.println("第" + (i + 1) + "个：" + object[i]);
}
}
}
