Android 读取指定路径文件

/**

* 文件读取
*
* @param dataFileName
*/
private void Dataprocessing(String dataFileName) {

String tempFile = dataFileName.trim();
if (tempFile.length() == 0)
return;
File file = new File(tempFile);
try {
InputStream stream2 = new FileInputStream(file);
//处理业务
} catch (FileNotFoundException e) {
e.printStackTrace();
}

}

Dataprocessing（传入文件路径）；如："/storage/emulated/0/pms/test.xml"
