我有以下RETROFIT API:

@POST("/payments")    
Observable<Response> saveCreditCard(@Body CreditCard creditCard)

CreditCard是一个RealmObject.

当我尝试使用我的API方法时:

CreditCard card = realm.createObject(CreditCard.class);
card.setWhateverField(...);
...
mApi.saveCreditCard(card)
    .subscribeOn(Schedulers.io())
    .observeOn(AndroidSchedulers.mainThread())
    .subscribe(...);

我收到以下错误:

如何使位图创建可点击？下面是我用于使用canvas创建位图的代码.

 public class DrawView extends View implements OnClickListener
{
    public DrawView(Context context)
    {
        super(context);
        paint = new Paint();
        image = BitmapFactory.decodeResource(getResources(), R.drawable.andmrktsmall);
    }

    @Override
    protected void onDraw(Canvas canvas)
    {
        super.onDraw(canvas);
        int canWidth = canvas.getWidth();
        int canHeight = canvas.getHeight();
        int width = (canWidth - 200) / 2;
        int height = (canHeight - 100) / 2;
        Bitmap indexcanvas = Bitmap.createScaledBitmap(image, 200, 100, true);
        canvas.drawBitmap(indexcanvas, width, height, paint);
        this.setBackgroundColor(Color.YELLOW);

    }

    @Override
    public void onClick(View v)
    {
        Toast.makeText(context, "View is clicked", 1).show();
    }

}

我正在将一个 java 项目从 weblogic 8.1 迁移到 weblogic 12c。

根据oracle文档，我已经转换了以下内容。

 1. Servicegen converted to jwsc task
 2. deployment descriptor has been modified
 3. Below annotations added in service implementation file

  @WebService
  @SoapBinding
  @SoapMessageHandler

在所有上述更改确实生成了war文件并部署在weblogic 12c服务器中之后，它会抛出如下错误

Unable to invoke annotation processor

<BEA-160228> App merge failed your application
weblogic.utils.compiler.ToolFailureException: unable to invoke annotation processor

我正在尝试使用Grgit插件,我想Grgit从一个单独的gradle文件中引用.

Gradle能够Grgit在我尝试这样的时候找到它:

./build.gradle:

buildscript {
    repositories {
        mavenCentral()
    }

    dependencies {
        classpath 'com.android.tools.build:gradle:0.10.+'
        classpath 'org.ajoberstar:gradle-git:0.8.+'
    }
}

import org.ajoberstar.grgit.*

def repo = Grgit.open(".")

但是,当我将最后两行移动到一个单独的行file.gradle(如下所示)时,它不起作用:

./build.gradle:

buildscript {
    repositories {
        mavenCentral()
    }

    dependencies {
        classpath 'com.android.tools.build:gradle:0.10.+'
        classpath 'org.ajoberstar:gradle-git:0.8.+'
    }
}

apply from: 'file.gradle'

./file.gradle:

import org.ajoberstar.grgit.*

def repo = Grgit.open(".")

显示错误:

Could not find property 'Grgit' on root project 'MyProject'.

我如何Grgit在单独的文件中使用？
