android UiAutomator用switch语句随机设置的方法

昨天又遇到随机设置的问题，之前用的是if，后来想想随机数不用那么大，不用强调什么几率，就换了一种方法，用swith写的，相比来说简单了一些。分享出来。

public void setSex() throws UiObjectNotFoundException{

Configurator.getInstance().setActionAcknowledgmentTimeout(750);

getUiObjectByText("个人资料 > ").clickAndWaitForNewWindow();

String sex = getUiObjextByResourceId("com.dianzhi.teacher.school:id/tv_sex_text_my_infomation_activity").getText();

getUiObjectByText("性别:").clickAndWaitForNewWindow();

int num = new Random().nextInt(3);

switch (num) {

case 0:

getUiObjectByText("初中").clickAndWaitForNewWindow();

getUiObjectByText("保存").clickAndWaitForNewWindow();

getUiObjectByText("个人资料 > ").clickAndWaitForNewWindow();

String newsubject0 = getUiObjextByResourceId("com.dianzhi.teacher.school:id/tv_sex_text_my_infomation_activity").getText();

assertEquals("修改性别失败！", "初中", newsubject0);

outputNotable("修改性别成功！");

UiDevice.getInstance().pressBack();

break;

case 1:

getUiObjectByText("高中").clickAndWaitForNewWindow();

getUiObjectByText("保存").clickAndWaitForNewWindow();

getUiObjectByText("个人资料 > ").clickAndWaitForNewWindow();

String newsubject1 = getUiObjextByResourceId("com.dianzhi.teacher.school:id/tv_sex_text_my_infomation_activity").getText();

assertEquals("修改性别失败！", "高中", newsubject1);

outputNotable("修改性别成功！");

UiDevice.getInstance().pressBack();

break;

case 2:

getUiObjectByText("取消").clickAndWaitForNewWindow();

getUiObjectByText("保存").clickAndWaitForNewWindow();

getUiObjectByText("个人资料 > ").clickAndWaitForNewWindow();

String newsex = getUiObjextByResourceId("com.dianzhi.teacher.school:id/tv_sex_text_my_infomation_activity").getText();

assertEquals("修改性别失败！", sex, newsex);

outputNotable("修改性别成功！");

UiDevice.getInstance().pressBack();

break;

default:

outputNotable("修改性别失败！");;

break;

}

Configurator.getInstance().setActionAcknowledgmentTimeout(1500);

}
