我想将EditText中的sharedPrefs文件保存到prefs mode_private textview，然后将其显示在String sal=ed.getText().toString();
int saly=Integer.parseInt(sal);
String prefs="myPrefs";
String Salaryflag="mySalary";
SharedPreferences sp=getSharedPreferences(prefs,Context.MODE_PRIVATE);
Editor ed=sp.edit();
ed.putInt(Salaryflag, saly);
ed.commit();
Toast.makeText(getBaseContext(), "Salary Saved", Toast.LENGTH_SHORT).show();
int c=sp.getInt(Salaryflag, 0);
String str=Integer.toString(c);
tv.setText(c);
中。

！
现在我要保存的数据是整数类型。现在问题是代码中没有显示错误，但是当我运行代码并输入数据并单击按钮应用程序时崩溃导致此错误！
MediaPlayer现在该怎么做才能删除它？
答案 0 :(得分：3)
更改
tv.setText(c);
到
tv.setText(str);
使用期望字符串而不是setText(CharSequence)的{{1}}期望资源ID。
