Question

我正在尝试为我的应用创建一个启动画面，当我只在splashScreen的布局文件中显示一些文本（使用约束布局）时，它工作得很好。但是当我添加一个imageView时，应用程序崩溃了，我不明白为什么。图片的文件大小只有299kb，所以它不是内存问题或者其他什么问题？关于为什么会发生这种情况以及如何解决问题的任何想法？这是我的xml文件：

<?xml version="1.0" encoding="utf-8"?>
<android.support.constraint.ConstraintLayout xmlns:app="http://schemas.android.com/apk/res-auto"
    xmlns:tools="http://schemas.android.com/tools"
    xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:gravity="center_horizontal|center_vertical"
    android:orientation="vertical"
    tools:context="com.spdesigns.funfacts.SplashScreen">

<ImageView
    android:id="@+id/logoImageView"
    android:layout_width="377dp"
    android:layout_height="293dp"
    android:layout_marginBottom="8dp"
    android:layout_marginEnd="8dp"
    android:layout_marginStart="8dp"
    android:layout_marginTop="8dp"
    app:layout_constraintBottom_toBottomOf="parent"
    app:layout_constraintEnd_toEndOf="parent"
    app:layout_constraintStart_toStartOf="parent"
    app:layout_constraintTop_toTopOf="parent"
    app:srcCompat="@drawable/logo" />

</android.support.constraint.ConstraintLayout>

SplashScreen.java

package com.spdesigns.funfacts;

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

public class SplashScreen extends AppCompatActivity {

private static final int Splash_Timer = 4000;

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

Logcat错误：

问题是ImageView使用GL纹理，在大多数设备上限制为2048x2048。最大纹理尺寸因设备而异，我看到的尺寸小到约1500x1500，大到4096x4096。

为此，您必须为每个维度创建一个图像，以确保它可以在所有设备中使用。查看此主题以获取更多信息。
