之前方法

adb shell screencap -p /data/local/tmp/screen.png
adb pull /data/local/tmp/screen.png E:/adb/screen.png

經(jīng)多次測試，耗時(shí)3000ms多，效率太低了

之后的方法

adb exec-out screencap -p > E:/adb/screen.png

經(jīng)多次測試，耗時(shí)10ms多，效率有了顯著的提升

在java中的實(shí)現(xiàn)

String path = "E:/screenshot.png";
String cmd = "adb exec-out screencap -p > " + path;
String [] command = {"cmd" , "/C" , cmd};
Runtime.getRuntime().exec(command)

以上代碼僅在Windows平臺(tái)cmd命令中有效，如果在Linux：

String path = "E:/screenshot.png";
String cmd = "adb exec-out screencap -p > " + path;
String [] command = {"sh" , "-c" , cmd};
Runtime.getRuntime().exec(command)
