android - 处理不同的屏幕尺寸 (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绘制-xxhdpi

现在我的问题是，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，它将被大量空白未使用的空间包围。但如果我在 Tab 上开发得很好，它在 Nexus 上就会完全爆炸。

我在这里读过

(http://www.techotopia.com/index.php/Handling_Different_Android_Devices_and_Displays)

添加一个名为drawable的文件夹

drawable-sw200dp
drawable-sw600dp
绘制-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和/或处理 xxhdpi 类别中不同尺寸的解决方法？

更新:-似乎导致问题的 XML 布局 (fragment_tutorial2.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:paddingTop="20dip">
    <TextView
        android:id="@+id/hint"
        style="@style/TutorialTitle1"
        android:layout_width="fill_parent"
        android:layout_height="wrap_content"
        android:text="@string/tut_text2" />

    <TextView
        android:id="@+id/hint2"
        style="@style/TutorialTitle2"
        android:layout_width="fill_parent"
        android:layout_height="wrap_content"
        android:layout_below="@id/hint"
        android:text="@string/tut_text3"/>

    <ImageView
        android:id="@+id/documentlist"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_centerVertical="true"
        android:layout_centerHorizontal="true"
        android:src="@drawable/documentlist" />

</RelativeLayout>

样式....

<style name="TutorialTitle1" parent="AppBaseTheme">
        <item name="android:textStyle">bold</item>
        <item name="android:gravity">center</item>
        <item name="android:textSize">50sp</item>
        <item name="android:textColor">@color/white</item>
        <item name="android:paddingTop">5dp</item>
    </style>

    <style name="TutorialTitle2" parent="AppBaseTheme">
        <item name="android:textStyle">bold</item>
        <item name="android:gravity">center</item>
        <item name="android:textSize">20sp</item>
        <item name="android:textColor">@color/white</item>
        <item name="android:paddingBottom">25dp</item>
    </style>

@安德鲁布拉姆威尔

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，最好调整图像到更小的尺寸。

并将其添加到您的 ImageView 中

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".

您可以在您的 list Application Tag 中设置 android:largeHeap="true" 。
