Java的内存不足错误加载一个Android活动的UI [英] Java Out of Memory Error while loading the UI of an Android Activity
问题描述
我一直在试图加载一个非常基本活动上的ImageButton，2 textViews，一个文本框和一个ImageView的。
I have been trying to load a very basic activity with on ImageButton, 2 textViews, a textField and an ImageView.
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools" android:layout_width="match_parent"
android:layout_height="match_parent"
android:clickable="false"
android:id="@+id/namescreenactivity">
<TextView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:textAppearance="?android:attr/textAppearanceLarge"
android:text="Welcome to your Pet House"
android:id="@+id/Welcome"
android:textColor="#ff000000"
android:textStyle="bold"
android:layout_marginTop="94dp"
android:layout_alignParentTop="true"
android:layout_centerHorizontal="true" />
<EditText android:id="@+id/edit_message"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:hint="@string/edit_message"
android:layout_marginTop="36dp"
android:textColor="#ff000000"
android:layout_below="@+id/Welcome"
android:layout_alignEnd="@+id/Welcome" />
<TextView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:textAppearance="?android:attr/textAppearanceMedium"
android:text="Name your pet"
android:id="@+id/NameLabel"
android:layout_alignTop="@+id/edit_message"
android:layout_alignStart="@+id/Welcome" />
<ImageView
android:layout_width="100dp"
android:layout_height="100dp"
android:src="@drawable/sun"
android:layout_alignBottom="@+id/Welcome"
android:layout_alignParentEnd="true"
android:layout_marginBottom="39dp"
android:id="@+id/sun" />
<ImageButton
android:layout_width="250dp"
android:layout_height="250dp"
android:id="@+id/imageButton"
android:src="@drawable/camel"
android:clickable="true"
android:scaleType="fitXY"
android:onClick="sendMessage"
android:layout_alignParentBottom="true"
android:layout_alignEnd="@+id/edit_message"
android:layout_marginBottom="31dp" />
和在MainActivity.java的OnCreate函数，我简单的调用的setContentView（R.layout.activity_main）;
但是，我的应用程序的内存使用情况图显示，我44MB左右使用（虽然我的所有图像应用中的总规模小于1MB，并用于ImageButton的是193KB的）。
And in MainActivity.java's OnCreate function I am simply calling setContentView(R.layout.activity_main); However, my application's memory usage graph shows that I am utilizing around 44MB (Although the total size of all my images in the app is less than 1MB and the one used for the ImageButton is 193KB).
我认为，这是什么原因我的应用程序崩溃并引发内存不足的错误
I believe that this is the reason my app crashes and throws an Out of Memory error
Caused by: java.lang.OutOfMemoryError: Failed to allocate a 138018828 byte allocation with 4194304 free bytes and 35MB until OOM

请帮我找出什么是错的，我怎么能解决这个问题。
Please help me figure out what's wrong and how I can resolve this issue.
推荐答案
有可能发生时，图像大，当他们被安置在绘（LDPI / MDPI ...）文件夹，以便Android操作系统往往会调整它们的大小根据需要，但在你的情况下，你说他们是非常小的，还是尽量把这些图片里：
it may happen when Images are big and when they are placed in drawable(ldpi/mdpi...) folder so android OS tends to resize them according to need, but in your case you said they are very small, still try putting those images inside:
res/drawable-nodpi
夹，因为它避免它们从重新缩放，也可以使用，因为它是
folder as it avoids them from rescaling and to be used as it is.
