安卓在共享空间中创建文件

放假几天

代码
/**
     * 创建文件
     *
     * @Param name
     * @return
     */
    public String fileCj(String name) {
//        获取外部存储路径
//        String path = Environment.getDownloadCacheDirectory().getAbsolutePath()+"/"+name;
//        Log.e("路径",Environment.getExternalStorageDirectory()+"");
//        Log.e("",Environment.getExternalStorageState().equals("mounted")+"");//查看外部存储是否存在


//        String path = context.getExternalFilesDir(null)+ "//" + name;

        File createFiles = new File(name);

        try {
            if (!createFiles.exists()) {
                createFiles.createNewFile();
            }
        } catch (IOException e) {
            Log.d("文件创建失败", "files err:" + e.getMessage());
        }

        return name;
    }
