Accessing private field of TextView in Android 11 using Kotlin 1.5.20?

Question

Saw the exiting question, but the accepted answer with 22 votes does not seem to compile. The answer is

val hello = Hello()
val f = Hello::class.memberProperties.find { it.name == "world" }
f?.let {
    it.isAccessible = true
    val w = it.get(hello) as World
    println(w.foo())
}

, but class has no memberProperties. The closest thing I could find is members, but it seems that it does not return the correct type. How can I get the private field "mEditor"?

    val f = TextView::class.members.find {it.name == "mEditor"};
    f?.let{
        it.isAccessible=true;
        val w = it.get(text2)
    }

Unresolved reference: isAccessible

TextView.java

@RemoteView
public class TextView extends View implements ViewTreeObserver.OnPreDrawListener {

....

/**
 * {@link EditText} specific data, created on demand when one of the Editor fields is used.
 * See {@link #createEditorIfNeeded()}.
 */
@UnsupportedAppUsage
private Editor mEditor;

Answer 1

You can use getDeclaredField just like java.

    val f = TextView::class.java.getDeclaredField("mEditor")
    f?.let {
        it.isAccessible = true
        Log.d("TYPE:",f.genericType.toString())
    }

Log Output:

TYPE:: class android.widget.Editor
