java - android.view.InflateException : Error inflating class androidx.constraintlayout.widget.ConstraintLayout

Question

我有一个非常令人沮丧的错误，我无法解释。我创建了一个 Android 应用程序，它使用 Androidx AppCompat 来使其与旧版本兼容。这是我的主要 Activity 布局文件: {Androidx}。

这是我的 java 文件:

public class SplashScreen extends AppCompatActivity {

@Override
public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_splash_screen);
    Handler handler = new Handler();
    handler.postDelayed(new Runnable() {
        @Override
        public void run() {
            startActivity(new Intent(SplashScreen.this, MainActivity.class));
            finish();
        }
    }, 1500);
}

这是我的 xml 文件:

<androidx.constraintlayout.widget.ConstraintLayout
xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:background="@drawable/splash_screen"
tools:context=".Activities.SplashScreen">

这是我的 gradle 文件

android {
compileSdkVersion 29
buildToolsVersion "29.0.3"
defaultConfig {
    applicationId "com.example.bloodbank"
    minSdkVersion 15
    targetSdkVersion 29
    versionCode 1
    versionName "1.0"
    testInstrumentationRunner "androidx.test.runner.AndroidJUnitRunner"
}
buildTypes {
    release {
        minifyEnabled false
        proguardFiles getDefaultProguardFile('proguard-android-optimize.txt'), 'proguard-rules.pro'
    }
}

} gradle 文件中的依赖项

dependencies {
implementation fileTree(dir: 'libs', include: ['*.jar'])
implementation 'androidx.appcompat:appcompat:1.1.0'
implementation 'androidx.constraintlayout:constraintlayout:1.1.3'
testImplementation 'junit:junit:4.12'
androidTestImplementation 'androidx.test.ext:junit:1.1.1'
androidTestImplementation 'androidx.test.espresso:espresso-core:3.2.0'

}

主要问题是我的应用程序说不幸的是应用程序已停止。 这是“运行”选项卡中的详细信息

它在splashcreen.java第16行显示错误 请帮助我清除此错误。

谢谢

Answer 1

您实际上收到了OutOfMemoryException。当您将高分辨率图像直接放入 View 中时，就会发生这种情况。就您而言，可能是@drawable/splash_screen。
