处理不同的屏幕尺寸 (Android)
Handling different screen sizes (Android)
自从开始 android 开发以来，我一直在使用以下可绘制文件夹结构...
drawable-mdpi
可绘制-hdpi
绘制-xhdpi
drawable-xxhdpi
现在我的问题是这个，我在 2 种不同的设备上进行测试
联想 Tab S8 - 1980*1200 - xxhdpi
Nexus 5 - 1080*1920 - xxhdpi
lenovo tabs 的物理屏幕尺寸大约是 Nexus 的两倍，但它们都从 drawable-xxhdpi 中提取图像。
这意味着，如果我最初为 nexus 构建我的应用程序，那么当部署在选项卡上时，它将被大量未使用的空白包围 space。但是，如果我在 Tab 上开发得很好，它在 Nexus 上就会完全爆炸。
我已阅读此处
(http://www.techotopia.com/index.php/Handling_Different_Android_Devices_and_Displays)
添加名称为
的可绘制文件夹
drawable-sw200dp
drawable-sw600dp
drawable-sw800dp
处理不同的屏幕尺寸，但这只会让我的应用程序在 Nexus 上崩溃。标签没问题。
谁能解释为什么这是 and/or 处理 xxhdpi 类别中不同尺寸的解决方法？

支持不同的设备屏幕对 Android 开发人员来说是一个挑战，直到您知道该怎么做。
要支持不同的设备，您可以执行以下操作（drawables）：
在普通项目中，您有以下可绘制文件夹 - 请记住，这与您希望在应用程序中支持的设备无关：
- 可绘制/
- drawable-mdpi/
- drawable-hdpi/
- drawable-xhdpi/
- drawable-xxhdpi/
- drawable-xxxhdpi/
为上述文件夹生成适当大小的图像后，您的应用 android 将自动为相应设备（例如 Nexus 4、5 英寸、7 英寸、10 英寸）加载正确的资源.
提供对不同屏幕尺寸（布局）的支持
例如使用您的开发设备（可以是 Nexus 4），然后您可以为您想要支持的其他屏幕尺寸创建布局文件夹。例如，我会创建以下文件夹：
- layout-sw300dp/
- layout-sw400dp/
- layout-sw600dp/
- layout-sw800dp/
在上面的布局文件夹中，您可以分别设置 xml files/views 的样式，这样使用不同屏幕的用户仍然会看到您希望他们看到的应用。
同样，android 系统将加载正确的资源。
希望这对您有所帮助，让我知道进展如何！祝你好运！

是这个原因，好像是你的位图太大了。
@AndrewBramwell
你的 logcat 抛出什么
Caused by: java.lang.OutOfMemoryError: Failed to allocate a 7607
http://developer.android.com/reference/java/lang/OutOfMemoryError.html
对于Android来说太大了，它会耗尽内存。所以，最好resize将图像缩小。
并将其添加到您的 ImageView
android:adjustViewBounds="true"
Set this to true if you want the ImageView to adjust its bounds to
preserve the aspect ratio of its drawable.
Must be a boolean value, either "true" or "false".
您可以在清单应用程序标记中设置 android:largeHeap="true"。
自从开始 android 开发以来，我一直在使用以下可绘制文件夹结构...
drawable-mdpi 可绘制-hdpi 绘制-xhdpi drawable-xxhdpi

支持不同的设备屏幕对 Android 开发人员来说是一个挑战，直到您知道该怎么做。
要支持不同的设备，您可以执行以下操作（drawables）：
在普通项目中，您有以下可绘制文件夹 - 请记住，这与您希望在应用程序中支持的设备无关：
- 可绘制/
- drawable-mdpi/
- drawable-hdpi/
- drawable-xhdpi/
- drawable-xxhdpi/
- drawable-xxxhdpi/
为上述文件夹生成适当大小的图像后，您的应用 android 将自动为相应设备（例如 Nexus 4、5 英寸、7 英寸、10 英寸）加载正确的资源.
提供对不同屏幕尺寸（布局）的支持
例如使用您的开发设备（可以是 Nexus 4），然后您可以为您想要支持的其他屏幕尺寸创建布局文件夹。例如，我会创建以下文件夹：
- layout-sw300dp/
- layout-sw400dp/
- layout-sw600dp/
- layout-sw800dp/
在上面的布局文件夹中，您可以分别设置 xml files/views 的样式，这样使用不同屏幕的用户仍然会看到您希望他们看到的应用。
同样，android 系统将加载正确的资源。
希望这对您有所帮助，让我知道进展如何！祝你好运！

是这个原因，好像是你的位图太大了。
@AndrewBramwell
你的 logcat 抛出什么
Caused by: java.lang.OutOfMemoryError: Failed to allocate a 7607

对于Android来说太大了，它会耗尽内存。所以，最好resize将图像缩小。
并将其添加到您的 ImageView
android:adjustViewBounds="true"
Set this to true if you want the ImageView to adjust its bounds to preserve the aspect ratio of its drawable.
Must be a boolean value, either "true" or "false".
您可以在清单应用程序标记中设置 android:largeHeap="true"。
