我想将Android内部存储空间中的.txt
文件读取为string
变量。
但是当我尝试加载字符串时,我收到了这个错误:
Cannot convert multipart to String
答案 0 :(得分:1)
我假设你的android的“内部存储”中有一个.txt文件
从内部存储空间
中读取文件调用openFileInput()并将其传递给要读取的文件的名称。这个 返回一个FileInputStream。使用read()从文件中读取字节。然后 用close()关闭流。
FileInputStream fis = context.openFileInput("test.txt", Context.MODE_PRIVATE);
InputStreamReader isr = new InputStreamReader(fis);
BufferedReader bufferedReader = new BufferedReader(isr);
StringBuilder sb = new StringBuilder();
String line;
while ((line = bufferedReader.readLine()) != null) {
sb.append(line);
}
bufferedReader.close();
如果您的文件位于 SD卡
//Find the directory for the SD Card
File sdcard = Environment.getExternalStorageDirectory();
//Get the text file
File file = new File(sdcard,"test.txt");
//Read text from file
StringBuilder text = new StringBuilder();
try {
BufferedReader br = new BufferedReader(new FileReader(file));
String line;
while ((line = br.readLine()) != null) {
text.append(line);
text.append('\n');
}
br.close();
}
catch (IOException e) {
//You'll need to add proper error handling here
}
