java-仅在从启动器启动应用程序时显示启动屏幕

我有这样的SplashActivity：

public class SplashActivity extends Activity {

    Handler Handler;

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

        Handler = new Handler();
        Handler.postDelayed(new Runnable() {
            @Override
            public void run() {
                Intent intent = new Intent(SplashActivity.this, MainActivity.class);
                startActivity(intent);
                finish();
            }
        }, 1500);

        Intent appLinkIntent = getIntent();
        String appLinkAction = appLinkIntent.getAction();
        Uri appLinkData = appLinkIntent.getData();
    }
}

其在AndroidManifext.xml中的声明如下：

<activity
    android:name=".SplashActivity"
    android:theme="@style/Splash"
    android:launchMode="singleTop">

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

    <meta-data
        android:name="android.app.shortcuts"
        android:resource="@xml/shortcuts"/>

    <intent-filter>
        <action android:name="android.intent.action.VIEW" />
        <category android:name="android.intent.category.DEFAULT" />
        <category android:name="android.intent.category.BROWSABLE" />

        <data
            android:host="brokenhearts.ml"
            android:scheme="http"
            android:pathPattern="/*"/>
    </intent-filter>

    <intent-filter>
        <action android:name="android.intent.action.VIEW" />
        <category android:name="android.intent.category.DEFAULT" />
        <category android:name="android.intent.category.BROWSABLE" />

        <data
            android:host="brokenhearts.ml"
            android:scheme="https"
            android:pathPattern="/*"/>
    </intent-filter>

    <intent-filter>
        <action android:name="android.intent.action.VIEW" />
        <category android:name="android.intent.category.DEFAULT" />
        <category android:name="android.intent.category.BROWSABLE" />

        <data
            android:host="www.brokenhearts.ml"
            android:scheme="http"
            android:pathPattern="/*"/>
    </intent-filter>

    <intent-filter>
        <action android:name="android.intent.action.VIEW" />
        <category android:name="android.intent.category.DEFAULT" />
        <category android:name="android.intent.category.BROWSABLE" />

        <data
            android:host="www.brokenhearts.ml"
            android:scheme="https"
            android:pathPattern="/*"/>
    </intent-filter>
</activity>

我在我的应用程序中使用WebViews.问题是,每当用户在我的应用程序的其他活动中点击我的网站的链接时,都会从SplashActivity重新开始.这在某种程度上是正确的,因为那是我添加意图的地方.但是,我想知道此设置是否还有其他方法仅在从启动器或从URL意图启动(当应用程序未运行时)而不是从URL意图启动时显示启动屏幕.当应用程序已经在前台运行时触发.

如果无法通过这种设置进行操作,我还有什么其他方法可以解决？

解决方法:

检查appLinkData是否为null,然后显示SplashScreen,否则启动MainScreen

public class SplashActivity extends Activity
{
    Handler Handler;

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

         Intent appLinkIntent = getIntent();
        String appLinkAction = appLinkIntent.getAction();
        Uri appLinkData;
        if(appLinkAction!=null)
        appLinkData = appLinkIntent.getData();

        if(appLinkData!=null)
        {
        Intent intent = new Intent(SplashActivity.this, MainActivity.class);
                                    startActivity(intent);
                                    finish();
        finish();
         return;
        }else
        {

        Handler = new Handler();
        Handler.postDelayed(new Runnable()
                            {
                                @Override
                                public void run()
                                {
                                    Intent intent = new Intent(SplashActivity.this, MainActivity.class);
                                    startActivity(intent);
                                    finish();
                                }
                            },
                1500);

       }
    }
}
