我在网上找到了这个程序,并想用在内部存储中创建新文件来替换它在外部存储中创建新文件的部分。如果您知道答案,请告诉我要编写的确切代码。我在这个网站上阅读了其他问题,它最终弄乱了程序。谢谢你。
布局
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:orientation="vertical" >
<ImageView
android:id="@+id/imageView1"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:contentDescription="@string/desc" />
</LinearLayout>
