这是我在gradle为我的android项目添加新依赖项时得到的以下错误.而且这个错误不是项目特定的.如果我在添加任何第三方插件时在任何其他Android项目错误中添加插件,我会得到相同的错误

我还发布了我的项目应用级gradle模块截图

应用级gradle模块

我甚Annotation Processor至在设置中启用了.仍然没有解决方案 请帮忙.

我试图webview从明文流量​​中获取保障.如文档中所述.我必须设定android:usesCleartextTraffic为false实现这一点.但这适用于API级别23及更高级别.我的最小sdk为22.如何确保应用程序在API级别23以下运行的设备上不会崩溃或产生任何问题？或者我如何以编程方式在application标签中设置该属性值Manifest.xml？

我正在尝试将类型为User从本机平台的自定义对象传递给 Flutter。该User班是一个库的一部分，并直接用于编辑不可访问。这是我的 android 和 iOS 代码实现。问题是我无法找到有关如何通过方法通道传递此对象的解决方案，以便我可以轻松地在 Dart 代码中解析它。

安卓部分：

private fun loginUser(uid: String, apiKey: String, result: MethodChannel.Result) {
        MyChat.login(uid, apiKey, object : MyChat.CallbackListener<User>() {
            override fun onSuccess(user: User) {
                Log.e(TAG, user.toString())
                result.success(hashMapOf("RESULT" to true, "AVATAR" to user.avatar,
                        "CREDITS" to user.credits,
                        "EMAIL" to user.email,
                        "LAST_ACTIVE" to user.lastActiveAt,
                        "NAME" to user.name,
                        "ROLE" to user.role,
                        "STATUS" to user.status,
                        "STATUS_MESSAGE" to user.statusMessage).toString())
            }

            override fun onError(p0: MyChatException?) {
                Log.e(TAG, p0?.message)
                result.error("FAILED", "Unable to create login", null)
            }
        })
    } …

我正在创建一个 Flutter 插件。但是当我尝试向插件的 iOS 部分添加依赖项时，我没有找到任何合适的指南。我在podspec插件文件中声明了依赖项。但是依赖项仅在example/iosthrough Pod 中可用，但我想在我ios的插件文件夹中访问该依赖项。这是我的podspec：

#
# To learn more about a Podspec see http://guides.cocoapods.org/syntax/podspec.html
#
Pod::Spec.new do |s|
  s.name             = 'comet_chat'
  s.version          = '0.0.1'
  s.summary          = 'A new Flutter plugin.'
  s.description      = <<-DESC
A new Flutter plugin.
                       DESC
  s.homepage         = 'http://example.com'
  s.license          = { :file => '../LICENSE' }
  s.author           = { 'Your Company' => 'email@example.com' }
  s.source           = { :path => '.' }
  s.source_files = 'Classes/**/*'
  s.public_header_files = 'Classes/**/*.h' …

我有一个EditText谁inputType是numberPassword.我想更改替换文本的点大小.它对我来说非常小(android默认).我想增加点大小.我怎样才能做到这一点？

我创建了一个抽象BaseFragment类，它将被其他具体Fragment类扩展。我想注入ViewModel我BaseFragment使用的Koin. 这是我的 BaseFragment：

abstract class BaseFragment<out VM : BaseViewModel, DB : ViewDataBinding>(private val mViewModelClass: Class<VM>) : Fragment() {

    val viewModel: VM by viewModel()

    open lateinit var binding: DB

    fun init(inflater: LayoutInflater, container: ViewGroup) {
        binding = DataBindingUtil.inflate(inflater, getLayoutRes(), container, false)
    }

    open fun init() {}
    @LayoutRes
    abstract fun getLayoutRes(): Int

    override fun onCreateView(inflater: LayoutInflater, container: ViewGroup?,
                              savedInstanceState: Bundle?): View {
        init(inflater, container!!)
        init()
        super.onCreateView(inflater, container, savedInstanceState)
        return binding.root
    }

    open …

我正在尝试实现以下布局。我想以占据整个屏幕宽度的方式放置项目：

预期布局：

实际布局：

这是我的 Recyclerview 项目的代码：

<?xml version="1.0" encoding="utf-8"?>
<layout xmlns:android="http://schemas.android.com/apk/res/android"
  xmlns:app="http://schemas.android.com/apk/res-auto"
  xmlns:tools="http://schemas.android.com/tools">

  <androidx.constraintlayout.widget.ConstraintLayout
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:paddingTop="@dimen/size_8dp"
    android:paddingStart="@dimen/size_20dp"
    android:paddingEnd="@dimen/size_20dp"
    android:paddingBottom="@dimen/size_8dp">

    <ImageView
      android:id="@+id/legendsItemIcon"
      android:layout_width="wrap_content"
      android:layout_height="wrap_content"
      app:layout_constraintTop_toTopOf="parent"
      app:layout_constraintStart_toStartOf="parent"
      app:layout_constraintEnd_toEndOf="parent"
      app:layout_constraintBottom_toTopOf="@+id/text_legend_status_name"
      />
    <TextView
      android:id="@+id/text_legend_status_name"
      android:layout_width="wrap_content"
      android:layout_height="wrap_content"
      tools:text="Low"
      android:textSize="@dimen/text_size_8sp"
      app:layout_constraintTop_toBottomOf="@+id/legendsItemIcon"
      app:layout_constraintStart_toStartOf="@+id/legendsItemIcon"
      app:layout_constraintEnd_toEndOf="@+id/legendsItemIcon"
      app:layout_constraintBottom_toBottomOf="parent"
      android:textColor="@color/legends_item_status_text_color"
      android:layout_marginTop="@dimen/size_4dp"
      />

  </androidx.constraintlayout.widget.ConstraintLayout>
</layout>

我怎样才能做到这一点？

我有一个场景，我想显示用户当前的天气数据，因为我正在获取他/她当前的纬度/经度并对其进行反向地理编码以获取城市名称。获得城市名称后，我将拨打网络电话并显示天气数据。除此之外，我还需要执行许多位置操作。

所以我创建了一个名为LocationUtils.kt. 我遵循 MVVM 架构，想知道哪个是调用LocationUtils方法的理想层，是view层还是viewmodel层还是data层。由于FusedLocationProvider需要context，如果我在ViewModel其中使用它会泄漏。那么如何解决这个问题呢？

LocationUtils.kt：

class LocationUtils {
  private lateinit var fusedLocationClient: FusedLocationProviderClient

  private fun isLocationEnabled(weakContext: Context?): Boolean {
    return when {
      Build.VERSION.SDK_INT >= Build.VERSION_CODES.P -> {
        // This is new method provided in API 28
        val locationManager = weakContext?.getSystemService(Context.LOCATION_SERVICE) as LocationManager
        locationManager.isLocationEnabled
      }
      Build.VERSION.SDK_INT >= Build.VERSION_CODES.KITKAT -> {
        // This is Deprecated in API 28
        val mode = Settings.Secure.getInt(
            weakContext?.contentResolver, Settings.Secure.LOCATION_MODE, …

我xml在我的项目的 drawable 文件夹中创建了一个渐变。我想xml在ImageViewusing 中加载它Glide。我怎样才能做到这一点 ？

使用 Glide 在 ImageView 中简单加载图像：

Glide.with(LoginActivity.this).load(R.drawable.a270).asBitmap().diskCacheStrategy(DiskCacheStrategy.RESULT).into(backgroundImage);

但是，如果使用上述更换相同的代码R.drawable.a270与R.drawable.gradient_background一个绘制的XML它不工作。

今天我将我的android工作室更新为3.2,当我尝试构建时gradle.我收到了以下错误.请有人帮我这个.
