解决方案

使用的 共享preferences 存储的屏幕已经显示的事实;在启动时，你检查这一点，如果是这样，你通过启动下一个，并调用的 完成（） 闪现屏幕立即生效。

So... I've developed a splash screen which is running successfully. How can I make it run once (and only once)? I'd like to build a registration screen but I only want it to appear for the user once.

Help!

import android.app.Activity;
import android.os.Bundle;
import android.os.Handler;
import android.content.Intent;
import com.nfc.linkingmanager.R;

public class SplashScreen extends Activity {

private boolean mIsBackButtonPressed;
private static final int SPLASH_DURATION = 1000; 

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

    setContentView(R.layout.splash_screen);

    Handler handler = new Handler();


    handler.postDelayed(new Runnable() {

        @Override
        public void run() {



            finish();

            if (!mIsBackButtonPressed) {

                Intent intent = new Intent(SplashScreen.this, NewCore.class);
                SplashScreen.this.startActivity(intent);
           }

        }

    }, SPLASH_DURATION);

}

 @Override
 public void onBackPressed() {
    mIsBackButtonPressed = true;
    super.onBackPressed();

}
}

解决方案

Use SharedPreferences to store the fact that the screen has already been displayed; upon start, you check this and if so, you replace the Activity by starting the next one and calling finish() for the splash screen immediately.
