Question

我最近尝试在我的应用中添加启动（启动）屏幕，但是我一直在尝试通过模拟器运行应用程序时出现错误。这是错误日志：

我的Android Studio，Gradle和Build工具都是最新的，我尝试多次清理和重建项目，但它没有帮助，没有相关的答案对这个问题有用;我尝试了所有的主题。这是我的style.xml：

<resources>

<!-- Base application theme. -->
<style name="AppTheme" parent="Theme.AppCompat.Light.DarkActionBar">
    <!-- Customize your theme here. -->
    <item name="colorPrimary">@color/colorPrimary</item>
    <item name="colorPrimaryDark">@color/colorPrimaryDark</item>
    <item name="colorAccent">@color/colorAccent</item>
</style>

<style name="SplashTheme" parent="Theme.AppCompat.NoActionBar">
    <item name="android:windowBackground">@drawable/background_splash</item>
</style>

<style name="AppTheme.NoActionBar">
    <item name="windowActionBar">false</item>
    <item name="windowNoTitle">true</item>
</style>

<style name="AppTheme.AppBarOverlay" parent="ThemeOverlay.AppCompat.Dark.ActionBar" />

<style name="AppTheme.PopupOverlay" parent="ThemeOverlay.AppCompat.Light" />

这是res / drawable目录中的background_splash.xml：

<?xml version="1.0" encoding="utf-8"?>
<layer-list xmlns:android="http://schemas.android.com/apk/res/android">
<item android:drawable="@android:color/darker_gray"/>
<item>
    <bitmap
        android:gravity="center"

        android:src="@mipmap/ic_launcher" />
</item>

</layer-list>

这是AndroidManifest.xml：

<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="com.aidin.workbook">
<application
    android:allowBackup="true"
    android:icon="@mipmap/ic_launcher"
    android:label="@string/app_name"
    android:roundIcon="@mipmap/ic_launcher_round"
    android:supportsRtl="true"
    android:theme="@style/AppTheme">
    <activity
        android:name=".SplashActivity"
        android:label="@string/app_name"
        android:theme="@style/SplashTheme">
        <intent-filter>
            <action android:name="android.intent.action.MAIN" />

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

    </activity>
</application>

最后这里是SplashActivity.java：

package com.aidin.workbook;

import android.content.Intent;
import android.support.annotation.Nullable;
import android.support.v7.app.AppCompatActivity;
import android.os.Bundle;

public class SplashActivity extends AppCompatActivity {

@Override
protected void onCreate(@Nullable Bundle savedInstanceState) {
    setTheme(R.style.SplashTheme);
    super.onCreate(savedInstanceState);
    Intent intent = new Intent(this, HomeActivity.class);
    startActivity(intent);
    finish();
}
}

这是Build.gradle：

apply plugin: 'com.android.application'
android {
compileSdkVersion 26
defaultConfig {
    applicationId "com.aidin.workbook"
    minSdkVersion 21
    targetSdkVersion 26
    buildToolsVersion "28.0.0-rc1"
    versionCode 1
    versionName "1.0"
    testInstrumentationRunner 
"android.support.test.runner.AndroidJUnitRunner"
}
buildTypes {
    release {
        minifyEnabled false
        proguardFiles getDefaultProguardFile('proguard-android.txt'), 
'proguard-rules.pro'
    }
}
}

dependencies {
implementation fileTree(dir: 'libs', include: ['*.jar'])
implementation 'com.android.support:appcompat-v7:26.1.0'
implementation 'com.android.support:design:26.1.0'
implementation 'com.android.support.constraint:constraint-layout:1.0.2'
testImplementation 'junit:junit:4.12'
androidTestImplementation 'com.android.support.test:runner:0.5'
androidTestImplementation 'com.android.support.test.espresso:espresso-
core:2.2.2'
}

Answer 1

在您的 background_splash.xml 中，您必须将位图src文件更改为必须为png格式而不是xml格式的可绘制文件像这样的 drawbles / ic_launcher.png

<?xml version="1.0" encoding="utf-8"?> <layer-list xmlns:android="http://schemas.android.com/apk/res/android"> <item android:drawable="@android:color/darker_gray"/> <item> <bitmap android:gravity="center" android:src=“@drawble/ic_launcher" /> </item> </layer-list>
