我如何指定从R.res.drawable动态获取的资源？

Question

I have some videos stored dynamically on R.res.raw .

For example, I can acces to the video called v.mp4 with this line of code:

String fileName = "android.resource://" + this.getPackageName() + "/" + R.raw.v;

OK, but I will describe the video that i must open with a string ("v"). Then, I tried to do this, but it didn't works:

String fileName = "android.resource://" + this.getPackageName() + "/" + R.raw+".v";

I can't do that, I get an error on R.raw

I also tried with this, but it doesn't works:

String fileName = "android.resource://" + this.getPackageName() + "/res/raw/"+"v.mp4";

How can I solve this?

Answer 1

If you want to get any resource Path then there are two ways :

1. Using Resource Name

   Syntax : android.resource://[package]/[res type]/[res name]

   Example : If icon.png image file is available in res/drawable folder you can get path like :

   String PATH="android.resource://com.my.package/drawable/icon";

2. Using Resource Id

   Syntax : android.resource://[package]/[resource_id]

   Example : If icon.png image file is available in res/drawable folder you can get path:

   String PATH="android.resource://com.my.package/" + R.drawable.icon;

This were the examples to get the URI of any image file stored in drawable folder.

Similarly you can get URIs of res/raw folder also.

它必须给您一个错误，R.raw.v.mp4（必须为R.raw.v）提供了通用的int引用，但没有提供String，因此您无法通过提供String路径来获取它。并看到它生成了只有应用程序才能理解的int值。

您可以按以下方式使用它：

 android.resource://your package/raw/v
