Android 兼容8.0及以上 App全局字体调节、禁止App字体随系统字体大小而更改

Posted 2023-04-12

参考技术A 在APP中，字体的大小单位一般会用sp，然而在改变系统字体大小时，App字体就会随着系统字体大小改变而改变，这就可能造成APP布局的错位。

造成这种情况的原因是，sp单位除了受屏幕密度影响外，还受到用户的字体大小影响，通常情况下，建议使用sp来跟随用户字体大小设置。除非一些特殊的情况,不想跟随系统字体变化的，可以使用dp”。按照这么说，布局宽高固定写死的地方应该统一用dp显示字体，因为一旦用户在设置中调大字体，宽高写死的布局显示就乱了。

针对这种情况，查找网上的方法也很多，大多是这样的方法 (重写 Application 或 BaseActivity 中的方法)：

我的Android App 支持7.0及以上版本但不支持6和5

【中文标题】我的Android App 支持7.0及以上版本但不支持6和5

【英文标题】：My Android App support in version 7.0 and upper version but not support version 6 and 5

【发布时间】：2020-03-27 17:13:03

【问题描述】：

其实我不知道是什么问题。我试过但不明白确切的问题！

compileSdkVersion 28,
minSdkVersion 21,
targetSdkVersion 28.

此问题仅在 android 版本 6 和 5 中出现。但我的应用在 android 7.0 及更高版本中正常运行。

这里是 Logcat 错误消息

【参考方案1】：

检查您的资源和其他人，当他们在应用程序将无法运行的更高版本文件夹中时。

【参考方案2】：

FATAL EXCEPTION: main Process: io.destreza.erp_dashboard, PID: 6025 java.lang.RuntimeException: Unable to start activity ComponentInfoio.destreza.erp_dashboard/io.destreza.erp_dashboard.activities.main.MainActivity: android.view.InflateException: Binary XML file line #53: Binary XML file line #53: Error inflating class ImageView at android.app.ActivityThread.performLaunchActivity(ActivityThread.java:2416) at

这就是问题在于尝试查找是否可以找到资源。如果它被找到但它是矢量图像，那么它可能会崩溃，因为某些矢量图像在旧的 android 版本中无法正常工作，也许可以尝试用 png 图像更改它

【讨论】：

我终于解决了！基本上这不是图像类型问题。我用 android:src="@drawable/logo_main" 代替 android:background="@drawable/logo_main" 谢谢 Nikhil
