未出现动画启动画面

Question

在这个项目中，我试图制作一个动画启动画面，它会在进入主画面之前出现activity，但是在我执行之后，启动画面没有出现，而是直接进入主画面activity。如何解决这个问题？

这是我的splashactivityclass

    private ImageView container;
    private AnimationDrawable animationDrawable;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_splash)
        container = findViewById(R.id.iv_icons);
        container.setBackgroundResource(R.drawable.mysplash_animation);

        animationDrawable = (AnimationDrawable) container.getBackground();

    }

    @Override
    protected void onResume() {
        super.onResume();

        animationDrawable.start();

        checkAnimationStatus(50, animationDrawable);
    }

    private void checkAnimationStatus(final int time, final AnimationDrawable animationDrawable) {
        Handler handler = new Handler();
        handler.postDelayed(new Runnable() {
            @Override
            public void run() {
                if (animationDrawable.getCurrent() != animationDrawable.getFrame(animationDrawable.getNumberOfFrames() - 1))
                    checkAnimationStatus(time, animationDrawable);
                else finish();
            }
        }, time);
    }
}

这是我的 manifest.xml

 <application
        android:allowBackup="true"
        android:exported="true"
        android:icon="@mipmap/ic_launcher"
        android:label="@string/app_name"
        android:roundIcon="@mipmap/ic_launcher_round"
        android:supportsRtl="true"
        android:theme="@style/Theme.AppCompat.NoActionBar">
        <activity android:name=".SplashActivity"></activity>
        <activity android:name=".MainActivity">
            <intent-filter>
                <action android:name="android.intent.action.MAIN" />

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

Answer 1

将您的 Splash Activity 设置为启动器 activity:

 <activity android:name=".MainActivity"></activity>

        <activity android:name=".SplashActivity">
            <intent-filter>
                <action android:name="android.intent.action.MAIN" />

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

Answer 2

请为 SplashActivity 提供 intentfilter

<application
            android:allowBackup="true"
            android:exported="true"
            android:icon="@mipmap/ic_launcher"
            android:label="@string/app_name"
            android:roundIcon="@mipmap/ic_launcher_round"
            android:supportsRtl="true"
            android:theme="@style/Theme.AppCompat.NoActionBar">
            <activity android:name=".SplashActivity">
                   <intent-filter>
                    <action android:name="android.intent.action.MAIN" />

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

            </activity>
        </application>

Answer 3

您必须在清单中更改此设置（您必须将启动器 activity 提供给 splashActivity）

    <application
    android:allowBackup="true"
    android:exported="true"
    android:icon="@mipmap/ic_launcher"
    android:label="@string/app_name"
    android:roundIcon="@mipmap/ic_launcher_round"
    android:supportsRtl="true"
    android:theme="@style/Theme.AppCompat.NoActionBar">
    <activity android:name=".SplashActivity">
     // below code you have to add //
    <intent-filter>
            <action android:name="android.intent.action.MAIN" />
            <category android:name="android.intent.category.LAUNCHER" />
    </intent-filter>
    </activity>
    <activity android:name=".MainActivity">
      //Remove from here//
    </activity>
</application>
