另一种方法是使用CountDownTimer实现

@Override
public void onCreate(Bundle savedInstanceState) {
     super.onCreate(savedInstanceState);
     setContentView(R.layout.splashscreen);

 new CountDownTimer(5000, 1000) { //5 seconds
      public void onTick(long millisUntilFinished) {
          mTextField.setText("seconds remaining: " + millisUntilFinished / 1000);
      }

     public void onFinish() {
          startActivity(new Intent(SplashActivity.this, MainActivity.class));
          finish();
     }

  }.start();
}

在Android Marshmallow之后，我想到的另一个有效使用启动画面的方法是在应用的启动画面中请求必要的Android权限。

似乎大多数应用程序都是这样处理权限请求的。

对话框是糟糕的ui，它们破坏了主要流程，让你决定运行时间，事实上，大多数用户甚至可能不在乎你的应用程序是否想在SD卡上写东西。他们中的一些人甚至不明白我们试图传达什么，直到我们用简单的英语翻译出来。 一次请求权限可以减少每次操作前的“if else”次数，使代码看起来不那么杂乱。

这是一个例子，你可以在你的splash活动中请求运行Android OS 23+的设备的权限。

如果所有权限都被授予或已经授予或应用程序正在Pre Marshmallow上运行，那么只需去显示主要内容，几乎半秒的延迟，以便用户可以欣赏我们在阅读这个问题时所付出的努力，并试图给予我们最好的。

Create an activity: Splash Create a layout XML file: splash.xml Put UI components in the splash.xml layout so it looks how you want your Splash.java may look like this: public class Splash extends Activity { @Override public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.splash); int secondsDelayed = 1; new Handler().postDelayed(new Runnable() { public void run() { startActivity(new Intent(Splash.this, ActivityB.class)); finish(); } }, secondsDelayed * 1000); } } change ActivityB.class to whichever activity you want to start after the splash screen check your manifest file and it should look like

<活动 android: name = "。屏” android: label = " @string / app_name " > > < /活动 <活动 android: name = "。飞溅” android: label = " @string / title_activity_splash_screen " > <意图过滤器> <action android:name="android.intent.action. main " /> <category android:name="android.intent.category. launcher " /> < /意图过滤器> > < /活动

public class SplashActivity extends Activity {

  Context ctx;

  @Override
  protected void onCreate(Bundle savedInstanceState) {
      super.onCreate(savedInstanceState);
      ctx = this;
      setContentView(R.layout.activity_splash);

      Thread thread = new Thread(){
          public void run(){
              try {
                  sleep(3000);
              } catch (InterruptedException e) {
                  e.printStackTrace();
              }

              Intent in = new Intent(ctx,MainActivity.class);
              startActivity(in);
              finish();
          }
      };
      thread.start();
  }
}

public class MainActivity extends Activity {

@Override

public void onCreate(Bundle savedInstanceState) {

    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);

    Thread t=new Thread()
    {

        public void run()
        {   

            try {

                sleep(2000);
                finish();
                Intent cv=new Intent(MainActivity.this,HomeScreen.class/*otherclass*/);
                startActivity(cv);
            } 

            catch (InterruptedException e) {
                e.printStackTrace();
            }
        }
    };
    t.start();
}

有时用户打开SplashActivity并立即退出，但应用程序仍然在SPLASH_SCREEN_DISPLAY_LENGTH后转到MainActivity。

为了防止它:在SplashActivity中，你应该在移动到MainActivity之前检查SplashActivity是否结束

public class SplashActivity extends Activity {

    private final int SPLASH_SCREEN_DISPLAY_LENGTH = 2000;

    @Override
    public void onCreate(Bundle icicle) {
        ...
        new Handler().postDelayed(new Runnable() {
            @Override
            public void run() {

                if (!isFinishing()) {//isFinishing(): If the activity is finishing, returns true; else returns false.
                    startActivity(new Intent(SplashActivity.this, MainActivity.class));
                    finish();
                }

            }, SPLASH_SCREEN_DISPLAY_LENGTH);
        }                             
   }                                
}
