我需要在所有活动/视图中包含标题图形.带标题的文件名为header.xml:

<?xml version="1.0" encoding="utf-8"?>
<FrameLayout xmlns:android="http://schemas.android.com/apk/res/android"
  android:layout_width="fill_parent" 
  android:layout_height="wrap_content"
  android:background="#0000FF" 
  android:padding="0dip">

  <ImageView xmlns:android="http://schemas.android.com/apk/res/android"
    android:src="@drawable/header"
    android:layout_width="fill_parent"
    android:layout_height="wrap_content"
    android:layout_margin="0dip"
    android:layout_marginTop="0dip"
    android:layout_marginBottom="0dip"
    android:padding="0dip"
    android:paddingTop="0dip"
    android:paddingBottom="0dip"
    android:layout_gravity="fill"
    android:background="#00FF00"
    />
</FrameLayout>

注意android:background="#00FF00"(绿色),它只是可视化的目的.

我将它们包含在我的视图中:

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout
  xmlns:android="http://schemas.android.com/apk/res/android"
  android:layout_width="fill_parent"
  android:layout_height="fill_parent"
  android:orientation="vertical"
  style="@style/white_background">

  <include layout="@layout/header" />
  (...)

因此,当我实际尝试时,结果看起来像左图像,而不是它应该是什么样的(右):

(1)这 - 橙色 - 部分是图像/ ImageView
(2)不受欢迎的绿色边框.注意:通常,绿色区域是透明的 - 它只是绿色,因为我设置了background.

注意顶部图像周围的绿色边框; 它是ImageView的一部分,我无法弄清楚它为什么存在或我如何摆脱它.它将所有填充和边距设置为0(但是当我省略它们时结果是相同的).图像是480x64px jpeg*,我把它放在res/drawable中(不是在其中一个中drawable-Xdpi).

(*jpeg,因为我似乎偶然发现了旧的png伽玛问题 - 起初我通过使绿色边框与图片橙色相同来解决问题,并且颜色不匹配.)

我在我的htc desire/2.2/Build 2.33.163.1和模拟器上试了一下.我也向#android-dev中的某个人描述了这个问题.她可以重现这个问题,但也没有解释.构建目标是1.6.

更新@tehgoose:此代码产生完全相同的顶部+底部填充结果.

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout
  xmlns:android="http://schemas.android.com/apk/res/android"
  android:layout_width="fill_parent"
  android:layout_height="fill_parent"
  android:orientation="vertical"
  style="@style/white_background">

  <!-- <include layout="@layout/header" />  --> …

我想写一个类似的查询,JpaRepository但它没有返回任何东西:

LIKE '%place%'- 没有用.

LIKE 'place' 工作得很好.

这是我的代码:

@Repository("registerUserRepository")
public interface RegisterUserRepository extends 
JpaRepository<Registration,Long>{

    @Query("Select c from Registration c where c.place like:place")
     List<Registration> findByPlaceContaining(@Param("place")String place);
}

我有自定义适配器的ListActivity.在每个视图中,它可能有一些按钮,我需要在其中实现OnClickListener.我需要在适配器中实现OnClickListener.但是,我不知道如何调用函数如startActivity()或setResult().因为适配器不会扩展到Activity.

那么解决这个问题的最佳方法是什么？谢谢

我想将带有 FCM 的 url 发送到 android 应用程序。单击 FCM 通知而不是打开启动器活动时，是否可以打开浏览器？我知道可以使用覆盖onMessageReceived()方法，但我不想这样做。我检查了click_action有效负载中的参数，但正如 Firebase 所说：

如果指定，则当用户单击通知时将启动具有匹配意图过滤器的活动。

我尝试click_action在 firebase cloudMessaging 面板中添加CustomData ，如下所示：

但它不起作用并打开应用程序。

我使用邮递员为此目的发送通知并添加click_action到这样的notification对象：

通知发送到我的设备，但当点击它时，什么也没发生！！！

重要提示：我的 apk 在 GooglePlay 上发布，我无法更改应用程序的源代码。

请任何人帮忙。

我正在使用PowerMockito模拟私有方法调用(privateApi),但它仍然进行privateApi调用,而这又调用另一个thirdPartCall.当thirdPartyCall抛出异常时,我遇到了问题.据我所知,如果我在模拟privateApi,它不应该进入方法实现细节并返回模拟响应.

public class MyClient {

    public void publicApi() {
        System.out.println("In publicApi");
        int result = 0;
        try {
            result = privateApi("hello", 1);
        } catch (Exception e) {
            Assert.fail();
        }
        System.out.println("result : "+result);
        if (result == 20) {
            throw new RuntimeException("boom");
        }
    }

    private int privateApi(String whatever, int num) throws Exception {
        System.out.println("In privateAPI");
        thirdPartyCall();
        int resp = 10;
        return resp;
    }

    private void thirdPartyCall() throws Exception{
        System.out.println("In thirdPartyCall");
        //Actual WS call which may be down while running the test cases
    } …

我想从 Windows 上托管的 Jenkins SSH 到 linux 服务器并在 linux 机器上执行命令，我尝试通过 ssh 插件安装发布并测试了全局配置中的连接，它工作正常，我不知道下一步如何进行在管道中。任何帮助，将不胜感激。

我有一个带有多个视图的recyclerView,其中每一行都是recyclerView.当我滚动recyclelerView时,在创建的每一行上都是滞后的.这是我的一些代码.在下面你可以看到main recyclerView的配置:

LinearLayoutManager mLayoutManager = new LinearLayoutManager(getContext(), LinearLayoutManager.VERTICAL, false);
    mRvPromotions.setLayoutManager(mLayoutManager);
    mRvPromotions.setItemViewCacheSize(20);
    mRvPromotions.setDrawingCacheEnabled(true);
    mRvPromotions.setHasFixedSize(true);
    mRvPromotions.setDrawingCacheQuality(View.DRAWING_CACHE_QUALITY_HIGH);
    mRvPromotions.setAdapter(adapter);

你可以在下面看到在适配器中绑定的内部recyclerView的代码:

mRvPromotion.setLayoutManager(new GridLayoutManager(itemView.getContext(), 3));
    mRvPromotion.setItemViewCacheSize(20);
    mRvPromotion.setDrawingCacheEnabled(true);
    mRvPromotion.setDrawingCacheQuality(View.DRAWING_CACHE_QUALITY_HIGH);
    adapter = new PlaylistPromotionsRVAdapter(new PlaylistModelCallBack(), new PlaylistPromotionVHFactory());
    mRvPromotion.setAdapter(adapter);
    adapter.submitList(getVM().getPlaylist());

我用mRvPromotion.setNestedScrollingEnabled(false);和ViewCompat.setNestedScrollingEnabled(childRecyclerView, false);,但laggy行为存在的钢.对于加载图像,我使用了Fresco并调整了配置.如何防止滞后滚动？

这是我的适配器:

public class PlaylistRVAdapter extends ListAdapter<PlayListPromotionAndSlider, BaseViewHolder> {

private final PlaylistPageVHFactory mFactory;
private final PublishSubject<PlaylistSliderVHAction> mClickSliderPS = PublishSubject.create();
private final PublishSubject<PlaylistPromotionsVHAction> mClickPromotionPS = PublishSubject.create();

@Inject
PlaylistRVAdapter(@NonNull PlaylistPromotionModelCallBack diffCallback, PlaylistPageVHFactory factory) {
    super(diffCallback);
    mFactory = factory;
}

@NonNull
@Override
public BaseViewHolder onCreateViewHolder(@NonNull ViewGroup …

我有一个recyclerView，每个项目都是一个recyclerView。我想在特定条件下滚动到内部recyclerView的自定义位置。我在innerRecyclerView上使用了这段代码，但是没有用：

innerRecyclerView.smoothScrollToPosition(position); 

和这个：

innerRecyclerView.scrollToPosition(position); 

还有这个：

layoutManager.scrollToPositionWithOffset(position, offset);

现在我有两个问题：

1）是否可以滚动到内部recyclerView的自定义位置？

2）如果可能的话，怎么办？

这是初始化主recyclerView：

LinearLayoutManager layoutManager = new LinearLayoutManager(getContext(), RecyclerView.VERTICAL, false);
        adapter = new FreightsListRVAdapter(new FreightListCallBack(), new FreightListVHFactory());
        rvFreightsList.setLayoutManager(layoutManager);
        rvFreightsList.setItemViewCacheSize(30);
        rvFreightsList.setNestedScrollingEnabled(true);
        rvFreightsList.setAdapter(adapter);

这是初始化innerRecyclerview：

LinearLayoutManager layoutManager = new LinearLayoutManager(itemView.getContext(), RecyclerView.VERTICAL, false);
        layoutManager.setItemPrefetchEnabled(true);
        layoutManager.setInitialPrefetchItemCount(7);
        rvFreights.setNestedScrollingEnabled(false);
        rvFreights.setLayoutManager(layoutManager);
        rvFreights.setItemViewCacheSize(20);

        adapter = new FreightsRVAdapter(new FreightCallBack(), new FreightSingleVHFactory());
        rvFreights.setAdapter(adapter);

这是我的主要recyclerView适配器：

public class FreightsListRVAdapter extends ListAdapter<FreightListModel, FreightListVH> {

    private final FreightListVHFactory mFactory;
    private final PublishSubject<FreightListVHAction> mClickUserPS = PublishSubject.create();

    @Inject
    public FreightsListRVAdapter(@NonNull FreightListCallBack diffCallback, FreightListVHFactory factory) {
        super(diffCallback);
        mFactory = factory; …
