老李推荐：第8章2节《MonkeyRunner源码剖析》MonkeyRunner启动运行过程-解析处理命令行参数 2
我们这一节会先去分析下monkeyrunner是如何对参数进行处理的，我们跳转到MonkeyRunnerOptions这个类里面的processOptions这个方法：
93 public static MonkeyRunnerOptions processOptions(String[] args)
94 {
95 int index = 0;
96
97 String hostname = DEFAULT_MONKEY_SERVER_ADDRESS;
98 File scriptFile = null;
99 int port = DEFAULT_MONKEY_PORT;
100 String backend = "adb";
101 Level logLevel = Level.SEVERE;
102
103 ImmutableList.Builder<File> pluginListBuilder = ImmutableList.builder();
104 ImmutableList.Builder<String> argumentBuilder = ImmutableList.builder();
105 while (index < args.length) {
106 String argument = args[(index++)];
107
108 if ("-s".equals(argument)) {
109 if (index == args.length) {
110 printUsage("Missing Server after -s");
111 return null;
112 }
113 hostname = args[(index++)];
114 }
115 else if ("-p".equals(argument))
116 {
117 if (index == args.length) {
118 printUsage("Missing Server port after -p");
119 return null;
120 }
121 port = Integer.parseInt(args[(index++)]);
122 }
123 else if ("-v".equals(argument))
124 {
125 if (index == args.length) {
126 printUsage("Missing Log Level after -v");
127 return null;
128 }
129
130 logLevel = Level.parse(args[(index++)]);
131 } else if ("-be".equals(argument))
132 {
133 if (index == args.length) {
134 printUsage("Missing backend name after -be");
135 return null;
136 }
137 backend = args[(index++)];
138 } else if ("-plugin".equals(argument))
139 {
140 if (index == args.length) {
141 printUsage("Missing plugin path after -plugin");
142 return null;
143 }
144 File plugin = new File(args[(index++)]);
145 if (!plugin.exists()) {
146 printUsage("Plugin file doesn't exist");
147 return null;
148 }
149
150 if (!plugin.canRead()) {
151 printUsage("Can't read plugin file");
152 return null;
153 }
154
155 pluginListBuilder.add(plugin);
156 } else if (!"-u".equals(argument))
157 {
158 if ((argument.startsWith("-")) && (scriptFile == null))
159 {
160
161
162 printUsage("Unrecognized argument: " + argument + ".");
163 return null;
164 }
165 if (scriptFile == null)
166 {
167
168 scriptFile = new File(argument);
169 if (!scriptFile.exists()) {
170 printUsage("Can't open specified script file");
171 return null;
172 }
173 if (!scriptFile.canRead()) {
174 printUsage("Can't open specified script file");
175 return null;
176 }
177 } else {
178 argumentBuilder.add(argument);
179 }
180 }
181 }
182
183 return new MonkeyRunnerOptions(hostname,
port,
scriptFile,
backend,
logLevel,
pluginListBuilder.build(),
argumentBuilder.build());
184 }
185 }
