android txt 文件导入数据库,如何在android studio中导入txt文件并将其用作字符串？...

将它放入资产并使用下面的函数进行阅读。

public String readFromAssets(String fileName, Context context) {

StringBuilder returnString = new StringBuilder();

InputStream fIn = null;

InputStreamReader isr = null;

BufferedReader input = null;

try {

fIn = context.getResources().getAssets()

.open(fileName, Context.MODE_WORLD_READABLE);

isr = new InputStreamReader(fIn);

input = new BufferedReader(isr);

String line = "";

while ((line = input.readLine()) != null) {

returnString.append(line);

}

} catch (Exception e) {

e.getMessage();

} finally {

try {

if (isr != null)

isr.close();

if (fIn != null)

fIn.close();

if (input != null)

input.close();

} catch (Exception e2) {

e2.getMessage();

}

}

return returnString.toString();

}

因此，在你的代码，你会初始化字符串作为

String longString = readFromAssets("helloworld.txt",mContext);
