Question

在我的申请中，我有超过20张图片是布局背景。当我添加另一个图像时，应用程序已经停止工作。

在方法onCreate()中同时加载图像。

main.xml：

<LinearLayout
    android:id="@+id/linearLayout27"
    android:layout_width="fill_parent"
    android:layout_height="fill_parent"
    android:background="@drawable/abc"
    android:orientation="vertical" >

onCreate()：

layout26 = (LinearLayout) findViewById(R.id.linearLayout27);
layout26.setOnClickListener(this);

我应该补充说，每幅图像的大小约为400 x 800像素。

我知道这个问题在这里已经出现了，但我无法为我的案件找到解决办法。

在使用android位图时，这是一个非常常见的问题。我加点这个

android:largeHeap=“true”

在清单文件中，但是最近我一直在使用Picasso jar，它在处理图像时非常好。默认情况下，它还提供缓存。这里有一个链接可以帮助您启动http://square.github.io/picasso/
