Question

当您通过屏幕按钮进入主屏幕然后再次点击应用程序打开它时，启动画面将无法完成，它只是返回到启动画面？为什么呢？

我正在调用finish（）;那么为什么它不会混淆

package com.webcraftbd.radio;

import android.app.Activity;
import android.content.Intent;
import android.content.SharedPreferences;
import android.os.Bundle;
import android.os.Handler;
import android.preference.PreferenceManager;

public class SplashScreen extends Activity
{
    // Set the display time, in milliseconds (or extract it out as a configurable parameter)
    private final int SPLASH_DISPLAY_LENGTH = 3000;

    @Override
    protected void onCreate(Bundle savedInstanceState)
    {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.splash);
    }

    @Override
    protected void onResume()
    {
        super.onResume();
        SharedPreferences sp = PreferenceManager.getDefaultSharedPreferences(this);
        // Obtain the sharedPreference, default to true if not available
        boolean isSplashEnabled = sp.getBoolean("isSplashEnabled", true);

        if (isSplashEnabled)
        {
            new Handler().postDelayed(new Runnable()
            {
                @Override
                public void run()
                {
                    //Finish the splash activity so it can't be returned to.
                    SplashScreen.this.finish();
                    // Create an Intent that will start the main activity.
                    Intent mainIntent = new Intent(SplashScreen.this, MainActivity.class);
                    SplashScreen.this.startActivity(mainIntent);
                }
            }, SPLASH_DISPLAY_LENGTH);
        }
        else
        {
            // if the splash is not enabled, then finish the activity immediately and go to main.
            finish();
            Intent mainIntent = new Intent(SplashScreen.this, MainActivity.class);
            SplashScreen.this.startActivity(mainIntent);
        }
    }}

如果它只是一个闪屏，为什么你不使用简单的东西？等;

protected void onCreate(Bundle radioPlayer) {
        super.onCreate(radioPlayer);
        setContentView(R.layout.main);

        Thread splash= new Thread(){
            public void run(){
                try{
                    sleep(3000);
                    startActivity(new Intent("com.test.MAINMENU"));
                } catch (InterruptedException e) {
                    e.printStackTrace();
                }
                finally {
                    finish();
                }
            }

        };
        splash.start();
    }

完成启动活动？
