Android 将Uri存储到本地文件，并获取路径
public class CopyFileByUri {
public static String getPath(Context context, Uri srcUri) {
String path=context.getFilesDir()+"/";//获取本地目录
File file=new File(path);
try {
InputStream inputStream = context.getContentResolver().openInputStream(srcUri);//context的方法获取URI文件输入流
if (inputStream == null) return "null";
OutputStream outputStream = new FileOutputStream(file);
copyStream(inputStream, outputStream);//调用下面的方法存储
inputStream.close();
outputStream.close();
return path;//成功返回路径
} catch (Exception e) {
e.printStackTrace();
return "null";//失败返回路径null
}
}
private static void copyStream(InputStream input, OutputStream output){//文件存储
final int BUFFER_SIZE = 1024 * 2;
