        if (instance == null) {
            instance = new ProgressIndicator();

        return instance;
    }

    private ProgressIndicator() {

            if (mDialog == null) {
                mDialog = new ProgressDialog(mActivity);
                mDialog.setTitle(mTitle);
                mDialog.setMessage(mText);              
                mDialog.setIndeterminate(true);
                mDialog.setCancelable(true);

                            interrupt();
                        }

            synchronized (this) {
                notifyAll();
            }
        }

        @Override
        public void run() {

            while (!dismiss) {
                System.out.println("waiting..."+!dismiss);

                synchronized (this) {
                    try {

                        ie.printStackTrace();
                    }
                }
            }
            System.out.println("Quitting...");
        }
    }
}

从AppController类调用：

private ProgressIndicator progressInstance = null;
public void showWaitingAnimation(Activity parent) {
    progressInstance.showIndicator(AppController.getInstance().currentActivity, "" , "", false);
}

测试类：

public class ProgressIndicatorTest extends
    ActivityInstrumentationTestCase2<MyTestActivity> {

    private Solo solo;

    private ProgressIndicator progressIndicatorInstance;

    public ProgressIndicatorTest() {
        super("com.test.activity",
                MyTestActivity.class);
    }

    protected void setUp() throws Exception {
        AppController.getInstance().startApp(getActivity());
        solo = new Solo(getInstrumentation(), getActivity());
        progressIndicatorInstance = ProgressIndicator.getInstance();
    }

    protected void tearDown() throws Exception {
        try {
            solo.finalize();
        } catch (Throwable e) {
            e.printStackTrace();
        }
        getActivity().finish();
        super.tearDown();
    }

    public void testGetInstance() {
        try {
            ProgressIndicator instance = ProgressIndicator.getInstance();
            assertNotNull(instance);
        } catch (Exception e) {
            fail("Creation of ExceptionDetails get instance failed!");
        }
    }

    public void testShowIndicator()  {
        Log.d("testCase Name:-", "testShowIndicator");

        ProgressIndicator progressInstance = ProgressIndicator.getInstance() ;
        progressInstance.showIndicator(AppController.getInstance().getCurrentActivity(), "" , "", false);
        //AppController.getInstance().showWaitingAnimation(AppController.getInstance().getCurrentActivity());
            solo.waitForDialogToClose(8000);
        try {
            progressInstance.dismissIndicator(AppController.getInstance().getCurrentActivity());
        } catch (InterruptedException e) {
            // TODO Auto-generated catch block
            e.printStackTrace();
        }
    }

    public void testDismissIndicator() {
        Log.d("testCase Name:-", "testDismissIndicator");
        ProgressIndicator progressInstance = ProgressIndicator.getInstance() ;
        progressInstance.showIndicator(AppController.getInstance().getCurrentActivity(), "" , "", false);
        solo.waitForDialogToClose(2000);
        try {
            progressInstance.dismissIndicator(AppController.getInstance().getCurrentActivity());
        } catch (InterruptedException e) {
            // TODO Auto-generated catch block
            e.printStackTrace();
        }
        //AppController.getInstance().showAppTerminationDialog("", AppController.getInstance().getCurrentActivity());
    }
}

在运行项目时，对话框可见＆amp;好好工作。但是在运行测试用例时只能看到黑屏，没有显示对话框（在使用solo.waitForDialogToClose（8000）之后;问题就出现了）。没有错误或异常被抛出，测试用例在Android Junit测试中被传递。如果有人知道如何在机器人测试的情况下显示此进度对话框，请分享。

在我的情况下，我可以成功显示进度对话框。我只是用

boolean showProgressBar = false;
showProgressBar = solo.waitForText("Verifying and Saving Credentials...", 1, 3000);

我希望它也应该对你有用.. :)）
