如何重新启动使用Robotium结束的活动solo.goBack()？

以下内容不会重新启动活动：（测试完成）

    solo.goBack();
    try {
    //  recreate activity here
    runTestOnUiThread(new Runnable() {
        public void run() {
        getInstrumentation().callActivityOnCreate(getActivity(), 
                              null);
        getInstrumentation().callActivityOnStart(getActivity());
        getInstrumentation().callActivityOnResume(getActivity());
        }});
    }

您如何重新启动以结尾的活动Solo.goBack()？

最小的例子

要重现这样的最小测试，请创建一个项目及其测试项目：

android create project -t 1 -p testRestart -k com.testRestart -a testactivity
cd testRestart
mkdir tests
cd tests
android create test-project -m .. -p .

将Robotium jar复制到该tests/libs文件夹。将此代码粘贴到文件中testactivityTest.java：

package com.testRestart;

import android.test.ActivityInstrumentationTestCase2;
import com.robotium.solo.Solo;

public class testactivityTest extends ActivityInstrumentationTestCase2<testactivity> {
    private Solo solo;

    protected void setUp() throws Exception {
    solo = new Solo(getInstrumentation(), getActivity());
    }
    public void tearDown() throws Exception {
    solo.finishOpenedActivities();
    }

    public testactivityTest() {
        super("com.testRestart", testactivity.class);

    }

    public void testDestroyAndRestart() {
        solo.goBack();
    try {
        //  recreate activity here
        runTestOnUiThread(new Runnable() {
            public void run() {
            getInstrumentation().callActivityOnCreate(getActivity(), 
                                  null);
            getInstrumentation().callActivityOnStart(getActivity());
            getInstrumentation().callActivityOnResume(getActivity());
            }});
    } catch ( Throwable t ) {
        throw new RuntimeException(t);
    }
    }
}

在测试文件夹中，执行

ant debug install
adb shell am instrument -w -e class com.testRestart.testactivityTest com.testRestart.tests/android.test.InstrumentationTestRunner
