有一个最简单的方法如下：
public void testScreen(){
UiDevice.getInstance().takeScreenshot(new File("/sdcards/test1.png"));
}
然后 main 方法调用此方法运行：
public static void main(String[] args) {
String jarName="Demoone";
String testClass="com.wch.Demo1";
String testName="testScreen";
String androidId="10";
new UiAutomatorHelper(jarName, testClass, testName, androidId);

}
然后控制台：
