我刚开始进行 android 开发(大约几个小时前)，由于某些原因，当我尝试运行我的应用程序时，它立即崩溃了。
这是我的 XML:
<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:paddingLeft="@dimen/activity_horizontal_margin"
android:paddingRight="@dimen/activity_horizontal_margin"
android:paddingTop="@dimen/activity_vertical_margin"
android:paddingBottom="@dimen/activity_vertical_margin" tools:context=".Login"
android:background="@drawable/bg"
android:id="@+id/login"
android:paddingEnd="@dimen/activity_horizontal_margin"
android:paddingStart="@dimen/activity_horizontal_margin">
<ImageView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:id="@+id/imageView"
android:src="@drawable/logo"
android:layout_alignParentTop="true"
android:layout_centerHorizontal="true"
android:layout_marginTop="-30dp"
android:layout_marginBottom="-10dp" />
<EditText
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:inputType="textEmailAddress"
android:id="@+id/uEmail"
android:background="#b4ffffff"
android:hint="@string/email"
android:singleLine="true"
android:textColor="#000"
android:paddingLeft="20dp"
android:paddingRight="20dp"
android:paddingTop="10dp"
android:paddingBottom="10dp"
android:layout_below="@+id/imageView"
android:layout_alignParentRight="true"
android:layout_alignParentEnd="true"
android:layout_marginTop="5dp"
android:layout_alignParentLeft="true"
android:layout_alignParentStart="true"
android:paddingEnd="20dp"
/>
</RelativeLayout>
这是我的日志:

我还没有对 java 文件进行任何更改。
不知道是不是相关的，背景是185KB，logo是8KB。
最佳答案
您的背景图片太大。您可以使用以下公式估算图像需要多少内存:
(width x height x 4) / 1000 = number of Kilobytes needed to render image
(4) 是每个像素的字节数。在你的情况下:
(1250 x 1900 x 4) / 1000 = 9500KB
您必须自己缩小图像。在这里查看:https://developer.android.com/training/displaying-bitmaps/load-bitmap.html
