小编goo*_*oid的帖子

我将我的项目更新为最新的Play服务classpath 'com.google.gms:google-services:1.5.0-beta2'.我也在app.gradle文件中使用最新版本的playservices:

compile 'com.google.android.gms:play-services-location:8.3.0'
compile 'com.google.android.gms:play-services-gcm:8.3.0'

但是当我编译时,Gradle会抛出异常,如下所示

Error:Execution failed for task ':app:processDebugGoogleServices'. > File google-services.json is missing from module root folder. The Google Services Plugin cannot function without it.

我正在为我的app使用Jackson JSON处理器.包括这个使用

compile 'com.fasterxml.jackson.core:jackson-databind:2.4.2'
compile 'com.fasterxml.jackson.core:jackson-annotations:2.4.2'.

我的proguard配置是.

## BEGIN -- Google Play Services proguard.txt
-keep class * extends java.util.ListResourceBundle {
    protected java.lang.Object[][] getContents();
}
# Keep SafeParcelable value, needed for reflection. This is required to support backwards

在Ubuntu中将android studio更新为1.1.0后总是显示此错误.我的logcat是:

我想发送一个数组作为名称值对作为httppost.My服务器只接受数组值.以下是我的代码片段..

public String SearchWithType(String category_name, String[] type,int page_no) {

    String url = "http://myURL";
    StrictMode.ThreadPolicy policy = new StrictMode.ThreadPolicy.Builder()
            .permitAll().build();
    StrictMode.setThreadPolicy(policy);

    String auth_token = Login.authentication_token;
    String key = Login.key;

    HttpClient httpclient = new DefaultHttpClient();
    HttpPost httppost = new HttpPost(url);

    try {
        List<NameValuePair> nameValuePairs = new ArrayList<NameValuePair>();
        nameValuePairs.add(new BasicNameValuePair("authentication_token",
                auth_token));
        nameValuePairs.add(new BasicNameValuePair("key", key));
        nameValuePairs.add(new BasicNameValuePair("category_name",
                category_name));
        int i = 0;
        nameValuePairs.add(new BasicNameValuePair("type", type[i]));
        nameValuePairs.add(new BasicNameValuePair("page", String.valueOf(page_no)));

        httppost.setEntity(new UrlEncodedFormEntity(nameValuePairs));

        HttpResponse response = httpclient.execute(httppost);
        HttpEntity entity = response.getEntity();
        eu = EntityUtils.toString(entity).toString();

    } catch (IOException …

为我的请求创建了一个凌空单例类.这是我的单例类

public class VolleySingleton {

    private static VolleySingleton instance;
    private RequestQueue reQueue;

    private VolleySingleton(Context context) {
        reQueue = Volley.newRequestQueue(context,new OkHttpStack(new OkHttpClient()));
    }

    public static VolleySingleton getInstance(Context context) {
        if(instance == null)
            instance = new VolleySingleton(context);
        return instance;
    }

    public RequestQueue getRequestQueue() {
        return reQueue;
    }

    public <T> void addToRequestQueue(Request<T> request) {
        request.setTag("app");
        request.setShouldCache(false);
        request.setRetryPolicy(new DefaultRetryPolicy(10000, DefaultRetryPolicy.DEFAULT_MAX_RETRIES,
                DefaultRetryPolicy.DEFAULT_BACKOFF_MULT));
        getRequestQueue().add(request);
    }
}

并且使用OKHTTP堆栈和我的Volley实现.这是我的 OKHttp.class

public class OkHttpStack implements HttpStack {

    private final OkHttpClient mClient;

    public OkHttpStack(OkHttpClient client) {
        this.mClient = client;
    } …

像这样在xml中膨胀我的Mapview

<android.support.v4.widget.NestedScrollView
        android:id="@+id/sv_offers"
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        android:paddingBottom="56dp"
        android:visibility="gone"
        app:layout_behavior="@string/appbar_scrolling_view_behavior">

        <LinearLayout
            android:layout_width="match_parent"
            android:layout_height="match_parent"
            android:orientation="vertical">

            <com.xys.widgets.CustomMapView
                android:id="@+id/mapView"
                android:layout_width="match_parent"
                android:layout_height="125dp"/>


        </LinearLayout>

    </android.support.v4.widget.NestedScrollView>

我已经实现了自定义Mapview如下: -

public class CustomMapView extends MapView {

    private ViewParent mViewParent;

    public CustomMapView(Context context) {
        super(context);
    }

    public CustomMapView(Context context, AttributeSet attrs) {
        super(context, attrs);
    }

    public CustomMapView(Context context, AttributeSet attrs, int defStyle) {
        super(context, attrs, defStyle);
    }

    public void setViewParent(@Nullable final ViewParent viewParent) { //any ViewGroup
        mViewParent = viewParent;
    }

    public CustomMapView(Context context, GoogleMapOptions options) {
        super(context, options);
    }

    @Override
    public …

我想在回收站视图的基础上添加一个页脚布局.下面是我的适配器视图,它也会扩展页眉布局以及其他项目.帮助赞赏!

public class SplitMembersAdapter extends RecyclerViewAdapter<SplitMember, SplitMemberViewHolder> {

        private final ArrayList<SplitMember> mSplitMembersList;
        private final ImageLoader mImageLoader;
        private static final int TYPE_HEADER = 0;
        private static final int TYPE_ITEM = 1;
        private int splitAmount;
        private boolean isAmountSplitted;

        public SplitMembersAdapter(ArrayList<SplitMember> members,ImageLoader imageLoader) {
            mSplitMembersList = members;
            mImageLoader = imageLoader;
        }

        @Override
        public int getItemCount() {
            return mSplitMembersList.size();
        }

        @Override
        public int getItemViewType(int position) {
            if (isPositionHeader(position)) {
                return TYPE_HEADER;
            }

            return TYPE_ITEM;
        }

        private static boolean isPositionHeader(int position) {
            return position == …

我得到这个错误Recyclerview的production,但不知道究竟在类

我做了什么

谷歌它发现https://issuetracker.google.com/issues/38375597,其中人们说它的android bug并修复了support lib 27.1.0

我更新了我的支持lib和buildVersion

support           : '27.1.0',
buildToolsVersion: '27.0.3',
compileSdkVersion : 26,

这种崩溃仍然发生

我的主要活动包括一个fragment.我在Activity的onResume()方法上设置了操作栏标题

@Override
    protected void onResume() {
        super.onResume();
        getActionBar().setTitle("My Account");
    }

它将动作栏标题显示为"My Account".当我调用片段时,我将片段的onResume()方法的标题设置为

@Override
    public void onResume() {
        super.onResume();
        getActivity().getActionBar().setTitle("Connected Accounts");
    }

它显示标题为.'Connected Accounts'但是当我回到活动时它仍然显示标题为'Connected Accounts',而它应显示为'My Account'.请帮助我知道这个奇特的案例中缺少一些东西.谢谢
