Question

我在Android Studio中添加了新的Activity。这个活动有一张图片。这是我的xml.file

的代码

<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout
xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
xmlns:app="http://schemas.android.com/apk/res-auto"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:paddingLeft="@dimen/activity_horizontal_margin"
android:paddingRight="@dimen/activity_horizontal_margin"
android:paddingTop="@dimen/activity_vertical_margin"
android:paddingBottom="@dimen/activity_vertical_margin"
app:layout_behavior="@string/appbar_scrolling_view_behavior"
tools:showIn="@layout/auxguide1"
tools:context=".AuxGuide1">

<ImageView
    android:layout_width="200dp"
    android:layout_height="200dp"
    android:id="@+id/imageView2"
    android:src="@drawable/logoauxguide"
    android:layout_centerVertical="true"
    android:layout_centerHorizontal="true" />

这是我的java类代码包com.example.gonalo.meu;

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

public class AuxGuide1 extends AppCompatActivity {

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.auxguide1);
        int secondsDelayed = 1;
        new Handler().postDelayed(new Runnable() {
            public void run() {
                startActivity(new Intent(AuxGuide1.this, MainActivity.class));

                finish();
            }
        }, secondsDelayed * 4000);
    }

}

它在我的手机中完美运行，但是当我在模拟器上运行时，它说“对不起，应用程序已停止＆＃34;

这是我的logcat

它不会停止我在该项目上的工作，但我知道为什么会发生这种情况对我很有帮助。很感激帮助。

Answer 1

如果Android设备必须显示图像，则必须将整个图像加载到内存中。在您的情况下logoauxguide是高分辨率图像，因此整个图像将不适合设备内存。因此OutOfMemoryError将会发生。

但是具有更大内存的设备，在这种情况下，您的手机将能够将图像加载到内存中。

如果要显示图像，必须在任何图像编辑工具中降低其分辨率（640x480就可以了）。除此之外，您不希望更高的内存图像增加您的apk大小：）
