Android actionbar上下文视图的私有字段名是什么？

A你好，，， 我正在使用robotium框架测试android应用程序，并使用robotium actionbarsherlock扩展在上下文操作栏菜单项上执行单击

这是我正在使用的函数

public void clickOnActionModeOverflowMenuItem(String text) {
    Activity activity = solo.getCurrentActivity();
    Log.d("aaaa", activity.toString());
    if (!(activity instanceof SherlockFragmentActivity)) {
            throw new IllegalStateException("This method should be called only in SherlockFragmentActivity.");
    }

    ActionBarContextView actionBarContextView = null;

    try {
            ActionBarSherlock actionBarSherlock = (ActionBarSherlock) invokePrivateMethodWithoutParameters(
                SherlockFragmentActivity.class, "getSherlock", activity);
            Log.d("eeee", actionBarSherlock.toString());
            actionBarContextView = (ActionBarContextView) getPrivateField("mActionModeView", actionBarSherlock);
            Log.d("dddd", actionBarContextView.toString());

    } catch (Exception ex) {
            Log.d(LOG_TAG, "Can not find methods to invoke action mode overflow button.");
    }

    if (actionBarContextView == null) {
            Assert.fail("Contextual actionbar is not shown.");
    }

    actionBarContextView.showOverflowMenu();
    sleeper.sleep();
    clicker.clickOnText(text, false, 1, true, 0);
}

所以，我想问一下这条线路

actionBarContextView = (ActionBarContextView) getPrivateField("mActionModeView", actionBarSherlock);

我如何知道私有字段名？

由于函数失败并抛出null actionBarContextView的断言失败…

您可以下载ActionBarSherlock的源代码，它应该会显示您正在查找的内容
