Question

当我第二次尝试打开应用程序时，它在启动屏幕之前加载的黑屏上停止，并且不加载启动屏幕我搜索过的链接 blank screen comes before splash

public class SplashActivity extends AppCompatActivity {

SharedPrefs prefs;
ImageView ivSplashLogo;

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);

    Crashlytics crashlyticsKit = new Crashlytics.Builder()
            .core(new CrashlyticsCore.Builder().disabled(BuildConfig.DEBUG).build())
            .build();

    Fabric.with(this, crashlyticsKit);

    Window window = getWindow();
    WindowManager.LayoutParams winParams = window.getAttributes();
    if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.KITKAT) {
        winParams.flags &= ~WindowManager.LayoutParams.FLAG_TRANSLUCENT_STATUS;
    }
    window.setAttributes(winParams);
    window.getDecorView().setSystemUiVisibility(View.SYSTEM_UI_FLAG_LAYOUT_STABLE | View.SYSTEM_UI_FLAG_LAYOUT_FULLSCREEN);

    setContentView(R.layout.activity_splash);

    prefs = new SharedPrefs(this);
    prefs.setCount(0);
    ivSplashLogo = findViewById(R.id.iv_splash_logo);
    latestVersionRequest();
}

我的gradle文件是：

android {
compileSdkVersion 28
buildToolsVersion '28.0.3'

defaultConfig {
    minSdkVersion 17
    targetSdkVersion 28
    multiDexEnabled true
    versionCode 61
    versionName "1.0.61"
    testInstrumentationRunner "androidx.test.runner.AndroidJUnitRunner"
}
buildTypes {
    release {
        minifyEnabled false
        proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
    }
}

packagingOptions {
    exclude 'META-INF/DEPENDENCIES'
    exclude 'META-INF/NOTICE'
    exclude 'META-INF/LICENSE'
    exclude 'META-INF/LICENSE.txt'
    exclude 'META-INF/NOTICE.txt'
    exclude 'META-INF/ASL2.0'
}
compileOptions {
    sourceCompatibility JavaVersion.VERSION_1_8
    targetCompatibility JavaVersion.VERSION_1_8
}

allprojects {
    repositories {
        maven { url "https://jitpack.io" }


    }
}

它在logcat中没有显示任何错误

Answer 1

无法从代码中复制此类问题，但我建议您使用以下技巧：-

将Splash设为启动器活动
几秒钟后，使用处理程序从启动活动导航到另一个活动
与它一起使用Intent标志为SINGLE_TOP和SINGLE_INSTANCE

Answer 2

有多个解决方案

1。<item name="android:windowAnimationStyle">@null</item>将此设置为您的活动样式

<item name="android:windowDisablePreview">true</item> 将此设置为您的活动样式
<item name="android:windowBackground">@drawable/slash_screen</item> 将此设置为您的活动样式
android:theme="@android:style/Theme.Translucent"

编辑

 <style name="AppTheme" parent="Theme.AppCompat.Light.NoActionBar">
<!-- Customize your theme here. -->
<item name="colorPrimary">@color/colorPrimary</item>
<item name="colorPrimaryDark">@color/colorPrimaryDark</item>
<item name="colorAccent">@color/colorAccent</item>
<item name="android:popupMenuStyle">@style/PopupMenu</item>
<item name="drawerArrowStyle">@style/DrawerArrowStyle</item>
<item name="android:textColorSecondary">@color/colorAccent</item>
<item name="colorControlHighlight">@color/light_grey</item>
<item name="windowActionModeOverlay">true</item>
<item name="android:actionMenuTextColor">@color/colorAccent</item>
<item name="android:actionModeBackground">@color/colorPrimary</item>

 <item name="android:windowDisablePreview">true</item>
</style>

以您的风格使用它并尝试

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

    prefs = new SharedPrefs(this);
    prefs.setCount(0);
    ivSplashLogo = findViewById(R.id.iv_splash_logo);
    latestVersionRequest();
}

将此代码替换为oncreate

希望如此对您有帮助
