我如何在Kotlin中绘制图片？

Question

我正在Android Studio中从事一个小项目。我已将drawable添加到res / drawable文件夹。

但是我无法从代码中获取它。我尝试了不同的方法：

ContextCompat.getDrawable(getActivity(), R.drawable.ic_training);

和

val drawable: Drawable? = ContextCompat.getDrawable(context.applicationContext, R.drawable.ic_training )
val drawable2: Drawable = R.drawable.ic_training

它们都返回错误的未解决引用。这是我的XML文件：

<vector
        android:id = "@+id/ic_training"
        android:alpha="0.85" android:height="24dp"
    android:viewportHeight="24.0" android:viewportWidth="24.0"
    android:width="24dp" xmlns:android="http://schemas.android.com/apk/res/android"
    android:name="ic_training"    >

Answer 1

在您的活动中做

val drawble = this.resources.getDrawable(R.drawable. ic_training,theme)

如果在片段中

val drawble = context!!.resources.getDrawable(R.drawable.ic_training,context!!.theme)
