我想首先在我的应用程序上显示一个 splashScreen 几秒钟，然后使用 java 中的计时器加载我所有的线程数据，然后我应该怎么做。

将启动画面活动添加到您的项目...现在将 SplashScree.java 文件代码替换为：

    package samples.splash.screen;

    import android.app.Activity;
    import android.os.Bundle;
    import android.os.Handler;

    /**
     * Splash screen activity
     *
     * @author Catalin Prata
     */
    public class SplashScreen extends Activity {

        // used to know if the back button was pressed in the splash screen activity and avoid opening the next activity
        private boolean mIsBackButtonPressed;
        private static final int SPLASH_DURATION = 2000; // 2 seconds


        public void onCreate(Bundle savedInstanceState) {
            super.onCreate(savedInstanceState);

            setContentView(R.layout.splash_screen);

            Handler handler = new Handler();

            // run a thread after 2 seconds to start the home screen
            handler.postDelayed(new Runnable() {

                @Override
                public void run() {

                    // make sure we close the splash screen so the user won't come back when it presses back key

                    finish();

                    if (!mIsBackButtonPressed) {
                        // start the home screen if the back button wasn't pressed already 
                        Intent intent = new Intent(SplashScreen.this, Home.class);
                        SplashScreen.this.startActivity(intent);
                   }

                }

            }, SPLASH_DURATION); // time in milliseconds (1 second = 1000 milliseconds) until the run() method will be called

        }

        @Override
       public void onBackPressed() {

            // set the flag to true so the next activity won't start up
            mIsBackButtonPressed = true;
            super.onBackPressed();

        }

}

而splash_screen xml 看起来像这样：你的drawables 中应该有任何图像，命名为：“splash_screen”

<?xml version="1.0" encoding="utf-8"?>

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
              android:layout_width="fill_parent"
              android:layout_height="fill_parent"
              android:background="@drawable/splash_screen"/>

现在让您的启动画面成为清单文件中的启动器活动，使其成为启动活动。为了使应用程序的标题栏向下，只需在清单中添加活动并添加主题，如下所示：

<activity android:name=".SplashScreen" android:theme="@android:style/Theme.Black.NoTitleBar.Fullscreen">
            <intent-filter>
                <action android:name="android.intent.action.MAIN">
                <category android:name="android.intent.category.LAUNCHER">
            </category></action></intent-filter>
        </activity>
