如果你使用变量作为处理程序和可运行的，然后像这样使用它。

private Handler handler;
private Runnable runnable;

handler = new Handler(Looper.getMainLooper());
    handler.postDelayed(runnable = () -> {
        // Do delayed stuff here
         handler.postDelayed(runnable, 1000);
    }, delay);

你还需要删除onDestroy()中的回调

@Override
public void onDestroy() {
    super.onDestroy();
    if (handler != null) {
        handler.removeCallbacks(runnable);
    }
}

import android.os.Looper
import android.os.Handler

inline fun delay(delay: Long, crossinline completion: () -> Unit) {
    Handler(Looper.getMainLooper()).postDelayed({
        completion()
    }, delay)
}

例子:

delay(1000) {
    view.refreshButton.visibility = View.GONE
}

被弃用的函数是Handler的构造函数。请改用Handler(loop . mylooper ()) .postDelayed(runnable, delay)

使用这个

Looper.myLooper()?.let {
    Handler(it).postDelayed({
        //Your Code
    },2500)
}

如果你使用变量作为处理程序和可运行的，然后像这样使用它。

private Handler handler;
private Runnable runnable;

handler = new Handler(Looper.getMainLooper());
    handler.postDelayed(runnable = () -> {
        // Do delayed stuff here
         handler.postDelayed(runnable, 1000);
    }, delay);

@Override
public void onDestroy() {
    super.onDestroy();
    if (handler != null) {
        handler.removeCallbacks(runnable);

协程 Kotlin

private val SPLASH_SCREEN_TIME_OUT_CONST: Long = 3000

override fun onCreate(savedInstanceState: Bundle?) {
    super.onCreate(savedInstanceState)
    setContentView(R.layout.activity_splash)
    window.setFlags(
        WindowManager.LayoutParams.FLAG_FULLSCREEN,
        WindowManager.LayoutParams.FLAG_FULLSCREEN
    )
    GlobalScope.launch {
        delay(SPLASH_SCREEN_TIME_OUT_CONST)
        goToIntro()
    }

}

private fun goToIntro(){
    startActivity(Intent(this, IntroActivity::class.java))
    finish()
}
