如何在处理程序中将 java 转换为 kotlin

new Handler().postDelayed(new Runnable(){
    @Override
    public void run() {
        /* Create an Intent that will start the Menu-Activity. */
        Intent mainIntent = new Intent(Splash.this,Menu.class);
        Splash.this.startActivity(mainIntent);
        Splash.this.finish();
    }
}, 3000);

Answer 1

Java 转换为 Kotlin:

Handler(Looper.getMainLooper()).postDelayed({
    val mainIntent = Intent(this, Menu::class.java)
    startActivity(mainIntent)
    finish()
}, 3000)

如果您使用的是 androidx-core-ktx 包，则有一个 extension function它将参数重新排序以更适合 Kotlin:

Handler(Looper.getMainLooper()).postDelayed(1000) {
    // Do something
}
