java - 启动画面显示太快，然后进入下一个 Java 类

Question

初始屏幕应该持续 3 秒，但当应用程序在 Genymotion Emulator 或 Android Studios Emulator 上运行时，它几乎完全跳过，这两个模拟器都可以完美运行其他应用程序。我不明白？

SplashScreen.java

package com.transcendencetech.juliospizzaprototype;

import android.content.Intent;
import android.os.Bundle;
import android.os.Handler;
import android.support.v7.app.AppCompatActivity;
import android.view.Window;

/**
 * Created by Stormy Forrester on 20/03/2016.
 */
public class SplashScreen extends AppCompatActivity {

  /** Called when the activity is first created. */
  @Override
  public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    this.requestWindowFeature(Window.FEATURE_NO_TITLE);
    setContentView(R.layout.splash_screen);

    int secondsDelayed = 4;
    new Handler().postDelayed(new Runnable() {
      public void run() {
        startActivity(new Intent(SplashScreen.this,
          SignInActivity.class));
        finish();
      }
    }, secondsDelayed * 3);
  }
}

Answer 1

您应该将秒数(例如 4)乘以 1000。

因为你必须以毫秒为单位给出它。

尝试将代码更改为

 @Override
  public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    this.requestWindowFeature(Window.FEATURE_NO_TITLE);
    setContentView(R.layout.splash_screen);

    int secondsDelayed = 4;
    new Handler().postDelayed(new Runnable() {
      public void run() {
        startActivity(new Intent(SplashScreen.this,
          SignInActivity.class));
        finish();
      }
    }, secondsDelayed * 1000);
  }
}
