Question

在我的adnroid项目中，我添加了一个启动画面，我显示它5秒钟，我想启动我的MainMenu活动，但是启动画面没有出现在屏幕上，它等待我9秒，然后直接进入我的MainMenu布局，如果我丢弃那部分代码它显示我的Splash我找不到我的代码有什么问题所以这里是我的Splash类

    public class Splash extends Activity
{

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

        Thread timer = new Thread(){
            @Override
            public void run() {

                try {
                    sleep(5000);

                } catch (InterruptedException e) {
                    e.printStackTrace();
                }
                finally {

                        Intent startIntent;
                        startIntent = new Intent("android.intent.action.MAINMENU");
                        startActivity(startIntent);

                }
            }
        };
        timer.run();

    }
}

这是我的MainMenu类

public class MainMenu extends Activity {

private static ArrayList<ArrayList> result = new ArrayList<ArrayList>();
TextView tx;
String temp;
@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.main_menu);
    tx = (TextView) findViewById(R.id.tvView);
    temp = "";
            try {
                result = MethodInfoGetter.methodRequest("BaskanOzgecmisGetir", "", "");
                Log.i("MainMenu","Result gelis vakti");
            } catch (IOException e) {
                // TODO Auto-generated catch block
                e.printStackTrace();
            } catch (XmlPullParserException e) {
                // TODO Auto-generated catch block
                e.printStackTrace();
            }
            /*if(result.isEmpty())
            {
                tx.setText("Result is emty");
            }
            else
            {
                for(int i = 0 ; i < result.size() ; i++)
                {
                    for(int j = 0 ; j < result.get(i).size() ; j++ )
                    {
                    temp += result.get(i).get(j) + " \n";

                    }   
                }
            }
            tx.setText(temp);*/

}

@Override
public boolean onCreateOptionsMenu(Menu menu) {
    // Inflate the menu; this adds items to the action bar if it is present.
    getMenuInflater().inflate(R.menu.main_menu, menu);
    return true;
}

    }

如果你们这里需要的是我的android清单文件

<application
    android:allowBackup="true"
    android:icon="@drawable/ic_launcher"
    android:label="@string/app_name"
    android:theme="@android:style/Theme.NoTitleBar" >"
    <activity
        android:name="com.BLKBelediye.balikesirbelediye.MainMenu"
        android:label="@string/app_name" >
        <intent-filter>
            <action android:name="android.intent.action.MAINMENU" />

            <category android:name="android.intent.category.DEFAULT" />
        </intent-filter>
    </activity>

    <activity
        android:name="com.BLKBelediye.balikesirbelediye.Splash"
        android:label="@string/app_name" >
        <intent-filter>
            <action android:name="android.intent.action.MAIN" />

            <category android:name="android.intent.category.LAUNCHER" />
        </intent-filter>
    </activity>



</application>

Answer 1

您需要使用方法start（）而不是run（）来启动线程，以便线程以异步方式运行。

用timer.start（）

替换timer.run（）

timer.run（）调用使您当前的UI线程休眠5秒钟。

Answer 2

使用CountDownTimer

public class MainActivity extends Activity 
{
private Timer_Countdown timer_Countdown = null;

@Override
public void onCreate(Bundle savedInstanceState) {

    super.onCreate(savedInstanceState);

    setContentView(R.layout.activity_main);
    timer_Countdown = new Timer_Countdown(5000, 1000);
    timer_Countdown.start();
}

class Timer_Countdown extends CountDownTimer
{
    public Timer_Countdown(long millisInFuture, long countDownInterval) {
        super(millisInFuture, countDownInterval);
    }

    @Override
    public void onFinish() {
        timer_Countdown.cancel();
         Intent startIntent;
         startIntent = new Intent("android.intent.action.MAINMENU");
         startActivity(startIntent);
    }

    @Override
    public void onTick(long millisUntilFinished) {

    }
}
}

我的启动画面看不到我是否添加睡眠方法
