java - 来自旧手机 API 18 的可绘制资源的 Android Resources$NotFoundException

Question

只有在使用 Android 4.3 和 API 18 的三星 Galaxy Nexus 手机上进行测试时，我才会遇到以下错误。

Caused by: android.content.res.Resources$NotFoundException: File res/drawable/ic_error.xml
 from drawable resource ID #0x7f020098
    at android.content.res.Resources.loadDrawable(Resources.java:2091)
    at android.content.res.TypedArray.getDrawable(TypedArray.java:601)
    at android.widget.TextView.<init>(TextView.java:803)
    at android.widget.EditText.<init>(EditText.java:60)

在我的 Acitivty.java 文件中，我尝试使用以下方法设置我的 vector 可绘制对象:

editTextNickname.setCompoundDrawablesWithIntrinsicBounds(0, 0, R.drawable.ic_error, 0);
editTextNickname.setCompoundDrawables(null, null,
    ContextCompat.getDrawable(getApplicationContext(), R.drawable.ic_error), null);

我在我的 build.gradle 文件中使用最新的支持库，如下所示:

apply plugin: 'com.google.gms.google-services'
apply plugin: 'com.android.application'

android {
  compileSdkVersion 24
  buildToolsVersion "23.0.3"

defaultConfig {
  applicationId "com.peprally.jeremy.peprally"
  minSdkVersion 16
  targetSdkVersion 24
  versionCode 1
  versionName "1.0"
  vectorDrawables.useSupportLibrary = true
}

    minifyEnabled false
    proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
  }
  debug {

  }
}

  mavenCentral()
}

我在 StackOverflow 上看到过类似的问题，但还没有很好的解决方案。如果有人有任何见解，请帮助!谢谢!

在忽略该问题并返回到它之后，我找到了解决 VectorDrawable 不受支持问题的可靠解决方案。除了建议的内容之外，您还可以使用以下代码创建 VectorDrawables:

public static Drawable getAPICompatVectorDrawable(Context callingContext, int resource_id) {
  if (android.os.Build.VERSION.SDK_INT >= 21) {
    return ContextCompat.getDrawable(callingContext.getApplicationContext(), resource_id);
  } else {
    return VectorDrawableCompat.create(
        callingContext.getResources(),
        resource_id,
        callingContext.getTheme());
  }
}

我在尝试将 vector 可绘制对象直接放入 xml 文件时也遇到了问题。而且我找不到解决这个问题的方法，所以我最终只是将它们从我的 xml 文件中取出并使用与上述相同的功能以编程方式将它们注入(inject) java 中。我在我的 xml 中使用 vector 绘图得到的错误如下所示，如果有人有更好的解决方案，我很乐意听到!

Answer 1

你能测试一下下面的代码吗？只是看看是否有效... 然后，我会用更多信息更新答案

public class MainActivity extends AppCompatActivity {
    static {
        AppCompatDelegate.setCompatVectorFromResourcesEnabled(true);
    }

    @Override
    protected void onCreate(Bundle arg0) {
        ...
    }
    ...
}

背景

我知道由于 this Google Issue - 205236 ，由于内存问题，对 vector Drawable 的支持被禁用。

该期的评论之一是:

To fix this issue, support for VectorDrawable from resource XML had to be removed.

然后，

In the next release I've added an opt-in API where you can re-enable the VectorDrawable support which was removed.

因此，他们在
中重新启用了该选项 Android Support Library 23.4.0

For AppCompat users, we’ve added an opt-in API to re-enable support Vector Drawables from resources (the behavior found in 23.2) via AppCompatDelegate.setCompatVectorFromResourcesEnabled(true) - keep in mind that this still can cause issues with memory usage and problems updating Configuration instances, hence why it is disabled by default.

也许，build.gradle 设置现在已经过时，您只需要在适当的 Activity 中启用它(但是，需要测试)。
