Android 读取资源文件实例详解

Android 读取资源文件实例详解

本文主要介绍 Android 读取资源文件，直接从 assets 读取，从 Raw 文件中读取，InputStream 转 String。

以下为直接从assets读取：

private InputStream getAssetsStream(String fileName) {
 InputStream is = null;
 try {
  is = getAssets().open(fileName);
  //is.close();
 } catch (IOException e) {
  e.printStackTrace();
 }
 return is;
}

以下为从Raw文件中读取：

public InputStream getFromRaw() {
 InputStream ins = null;
 try {
  ins = getResources().openRawResource(R.raw.area);
 } catch (Exception e) {
  e.printStackTrace();
 }
 return ins;
}

下面是 InputStream 转 String

private String InputStreamToString(InputStream inputStream) {
 String result = null;
 try {
  int length = inputStream.available();
  byte [] buffer = new byte[length];
  inputStream.read(buffer);
  result = EncodingUtils.getString(buffer, "UTF-8");
 } catch (Exception e) {
  e.printStackTrace();
 }
 return result;
}
