我想讀/寫幾個字符串轉換成Android文件Android的讀/寫幾個字符串
所以我寫的樹EditTexts信息
public void save(Person p) {
try {
FileOutputStream fos = openFileOutput(FILENAME, Context.MODE_PRIVATE);
fos.write(p.getName().getBytes());
fos.write(p.getSurname().getBytes());
fos.write(p.getAge().getBytes());
fos.close();
Toast toast = Toast.makeText(getApplicationContext(),
"Info was saved!", Toast.LENGTH_SHORT);
toast.show();
} catch (FileNotFoundException e){
e.printStackTrace();
Toast toast = Toast.makeText(getApplicationContext(),
"File not found exeption!", Toast.LENGTH_SHORT);
toast.show();
} catch (IOException e) {
e.printStackTrace();
Toast toast = Toast.makeText(getApplicationContext(),
"Input/Output Exeption!", Toast.LENGTH_SHORT);
toast.show();
}
}
我嘗試加載回的信息與方法
private void load(){
String value = "";
FileInputStream fis;
try {
fis = openFileInput(FILENAME);
byte[] input = new byte[fis.available()];
while(fis.read(input) != -1) {
value += new String(input);
}
edName.setText(value);
while(fis.read(input) != -1) {
value += new String(input);
}
edSurname.setText(value);
while(fis.read(input) != -1) {
value += new String(input);
}
edAge.setText(value);
fis.close();
} catch (FileNotFoundException e) {
e.printStackTrace();
} catch (IOException e) {
e.printStackTrace();
Toast toast = Toast.makeText(getApplicationContext(),
"Input/Output Exeption!", Toast.LENGTH_SHORT);
toast.show();
}
}
它加載信息,但所有數據都組合在一行中。我如何讀取行的一些數據行?
或者我可以寫/讀一些類及其字段?(在我的例子有類人用領域的姓名,年齡,男)
它的工作原理,謝謝 – user2105282 2013-03-09 08:35:03
