AndroidJavaRunnable 是 java.lang.Runnable 对象的 Unity 表示。
请注意,这是一个委托。因此,每次将其作为参数传递给 Java 时,都会创建一个新的 java.lang.reflect.Proxy 对象。这意味着多次向 Java 传递 AndroidJavaRunnable 类型的变量时,每次均会生成一个具有不同哈希码值的新 Java 对象。这也意味着,对 Java 对象(创建为 AndroidJavaRunnable 变量的表示)调用 equals()
将始终返回 false,即使在与自身比较时也如此。
using UnityEngine; using System.Collections;
public class ExampleClass : MonoBehaviour { // Pass execution context over to the Java UI thread. void Start() { AndroidJavaClass unityPlayer = new AndroidJavaClass("com.unity3d.player.UnityPlayer"); AndroidJavaObject activity = unityPlayer.GetStatic<AndroidJavaObject>("currentActivity"); activity.Call("runOnUiThread", new AndroidJavaRunnable(runOnUiThread)); }
void runOnUiThread() { Debug.Log("I'm running on the Java UI thread!"); } }
