下面是来自相机的示例代码意图:

val intent = Intent(MediaStore.ACTION_IMAGE_CAPTURE)
    startActivityForResult(intent, REQUEST_CAMERA)

注意:当我从相机按回来时,活动结果显示如下:

java.lang.RuntimeException:将结果ResultInfo {who = null,request = 65537,result = 0,data = null}传递给activity并且失败:java.lang.IllegalArgumentException:指定为非null的参数为null:

试着找出这样的解决方案:

 override fun onActivityResult(requestCode: Int, resultCode: Int, data: Intent) { 
           try {
                when(resultCode){
                    Activity.RESULT_CANCELED -> {
                        System.out.println("nothing")
                    }
                    Activity.RESULT_OK -> {
                        if (requestCode == SELECT_FILE)
                            onSelectFromGalleryResult(data)
                        else if (requestCode == REQUEST_CAMERA)
                            onCaptureImageResult(data)
                    }
                }
            }catch (e:NullPointerException){
                e.printStackTrace()
            }
}

仍然没有解决问题,因为当我做debuging日志时它不会出现在func onactivityresult如果我按下从相机返回而不捕获图像.从画廊工作中拍摄照片和拾取图像就像魅力一样.

谢谢.请帮助我解决这个问题,因为一路上解决方案不能正常工作.似乎谷歌必须覆盖有趣的onresultactivity(结果代码!!:Int)< - 这个应该返回非null.

我有编译新gradle的问题,如下所示:

错误:找不到com.android.tools.build:gradle:3.0.0-beta2.在以下位置搜索:file:/ C:/ Program Files/Android/android-studio-preview/gradle/m2repository/com/android/tools/build/gradle/3.0.0-beta2/gradle-3.0.0-beta2 .pom文件:/ C:/ Program Files/Android/android-studio-preview/gradle/m2repository/com/android/tools/build/gradle/3.0.0-beta2/gradle-3.0.0-beta2.jar https: //jcenter.bintray.com/com/android/tools/build/gradle/3.0.0-beta2/gradle-3.0.0-beta2.pom https://jcenter.bintray.com/com/android/tools/build /gradle/3.0.0-beta2/gradle-3.0.0-beta2.jar 必需者:项目:打开文件

这是我的傻瓜:

buildscript {

repositories {
    jcenter()
}
dependencies {
    classpath "com.android.tools.build:gradle:3.0.0-beta2"
    classpath "org.jetbrains.kotlin:kotlin-gradle-plugin:$kotlin_version"

    // NOTE: Do not place your application dependencies here; they belong
    // in the individual module build.gradle files
}
