sleep(2000);
} public void testMenu(){ UiDevice.getInstance().pressMenu();
sleep(2000);

import com.android.uiautomator.testrunner.UiAutomatorTestCase;public class Test extends UiAutomatorTestCase { public void testHome(){ UiDevice.getInstance().pressHome();
sleep(2000);
} public void testMenu(){ UiDevice.getInstance().pressMenu();
sleep(2000);
} public void testRecent() throws RemoteException{ UiDevice.getInstance().pressRecentApps();
sleep(2000);
} public void testKeyCode(){ UiDevice.getInstance().pressKeyCode(KeyEvent.KEYCODE_A); //小写a
UiDevice.getInstance().pressKeyCode(KeyEvent.KEYCODE_B); //小写b
UiDevice.getInstance().pressKeyCode(KeyEvent.KEYCODE_C); //小写c UiDevice.getInstance().pressKeyCode(KeyEvent.KEYCODE_A,1); //大写A
UiDevice.getInstance().pressKeyCode(KeyEvent.KEYCODE_B,1); //大写B
UiDevice.getInstance().pressKeyCode(KeyEvent.KEYCODE_C,1); //大写C }}
