我目前正在开发一个带有启动画面并带有声音的应用程序。启动画面完成后，我希望它能够进入我的主菜单。我的问题是播放声音后，它总是崩溃。我尝试过其他具有相同问题的线程，但执行方法不同，但在启动屏幕的末尾会不断崩溃。

编辑：当我运行该应用程序时，我的事件日志显示该应用程序已成功运行，未发现任何错误。 我运行了调试器，它说

E/ArrayAdapter: You must supply a resource ID for a TextView
D/AndroidRuntime: Shutting down VM
E/AndroidRuntime: FATAL EXCEPTION: main
    Process: com.example.finalproject,PID: 12755
    java.lang.IllegalStateException: ArrayAdapter requires the resource ID to be a TextView

Caused by: java.lang.ClassCastException: android.widget.RelativeLayout cannot be cast to android.widget.TextView
        at android.widget.ArrayAdapter.createViewFromResource(ArrayAdapter.java:388)

我认为一定是因为我的Mainactivity导致了问题。

我的启动代码：

public class Splashactivity extends AppCompatactivity {

    MediaPlayer ourSound;

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

        Thread timer = new Thread(){
            @Override
            public void run(){
                try {
                    ourSound = MediaPlayer.create(Splashactivity.this,R.raw.splashsound);
                    ourSound.start();
                    sleep(4000);
                } catch (InterruptedException e){

                } finally {
                    Intent i = new Intent(Splashactivity.this,Mainactivity.class);
                    startactivity(i);
                } // end finally
            } // end run
        };
        timer.start();
    } // end onCreate
    @Override

    protected void onPause(){
        super.onPause();
        ourSound.release();

    } // end onPause
} // end Splashactivity

我的Mainactivity代码：

public class Mainactivity extends Listactivity {

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        //setContentView(R.layout.activity_main);
        String[] mainmenu = {"Websites","Directions","Scheduling","Photos"};
        setListAdapter(new ArrayAdapter<String>(this,R.layout.activity_main,mainmenu));
    } // end onCreate

    protected void onListItemClick(ListView l,View v,int position,long id) {
        switch (position) {
            case 0:
                startactivity(new Intent(Mainactivity.this,Websites.class));
                break;
            case 1:
                startactivity(new Intent(Mainactivity.this,Directions.class));
                break;
            case 2:
                startactivity(new Intent(Mainactivity.this,Scheduling.class));
                break;
            case 3:
                startactivity(new Intent(Mainactivity.this,Photos.class));
                break;
        } // end switch
    }// end onListItemClick
} // end Mainactivity
