当我通过基于 Roboelectric 和 JUnit 的测试用例调用 getSupportActionBar() 方法时,该方法返回 null。
这是我的简单测试用例:
package com.mobile.test;
import static org.hamcrest.CoreMatchers.equalTo;
import static org.junit.Assert.assertEquals;
import static org.junit.Assert.assertThat;
import org.junit.Test;
import org.junit.runner.RunWith;
import org.robolectric.Robolectric;
import org.robolectric.RobolectricTestRunner;
import android.app.Activity;
import android.content.Intent;
import com.mobile.android.core.R;
import com.mobile.android.core.activity.MainActivity;
import com.mobile.android.core.activity.TestActivity;
@RunWith(RobolectricTestRunner.class)
public class NavigationDrawerTest {
private Activity activity;
@Test
public void testNavigationDrawer() {
activity = Robolectric.buildActivity(MainActivity.class).create().get();
String hello = activity.getResources().getString(R.string.drawer_open);
System.out.println(hello);
assertEquals(hello, "Menu");
}
}
这是我的活动课程:
public class MainActivity extends ActionBarActivity {
// Drawer related
private DrawerLayout mDrawerLayout;
private ListView mDrawerList;
private ActionBarDrawerToggle mDrawerToggle;
String[] mDrawerOptions;
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
// enable ActionBar app icon to behave as action to toggle nav-drawer
if (getSupportActionBar() != null) {
getSupportActionBar().setDisplayHomeAsUpEnabled(true);
getSupportActionBar().setHomeButtonEnabled(true);
}
}
}
关于如何解决这个问题的任何好主意?我是否必须编写一些影子活动,或者有人知道如何使用 RObolectric 处理这些操作栏问题吗?
谢谢你的帮助
