Android即使在应用程序终止时也如何保存editText的值

Question

I made this app which the user inputs the school name, and it will link to the website. So, I want to know how to save the school name, so you don't have to put it in every time you open the app. Thank you.

My app contains an edittext, a go button (Which I want to use it as a save also), and a webview.

Answer 1

我建议您查看http://developer.android.com/training/basics/data-storage/index.html对于这一点，这里只存储一个字符串，我将使用SharedPreference来查找您需要在培训指南上；）

Answer 2

you can save the value using something like this:

final EditText eActNametwo = (EditText)findViewById(R.id.eACTNametwo);
    final EditText eActBudtwo = (EditText)findViewById(R.id.eACTBudtwo);

    bCreatetwo = (Button)findViewById(R.id.bCreateActivitytwo);
    bCreatetwo.setOnClickListener(new View.OnClickListener() {

        @Override
        public void onClick(View v) {
            // TODO Auto-generated method stub
            SharedPreferences settingstwo = getSharedPreferences(actnamefiletwo,0);
            SharedPreferences.Editor editortwo = settingstwo.edit();
            editortwo.putString("nametwo", eActNametwo.getText().toString());
            editortwo.putString("budtwo", eActBudtwo.getText().toString());
            editortwo.commit();
        }
    });

and then u call the value somewhere using this

entvActNametwo = (TextView) findViewById(R.id.tvActNametwo);
    tvActBudtwo = (TextView) findViewById(R.id.tvActBudtwo);
    SharedPreferences settingstwo = getSharedPreferences(actnamefiletwo, 0);
    tvActNametwo.setText(settingstwo.getString("nametwo", ""));
    tvActBudtwo.setText(settingstwo.getString("budtwo", ""));

you will need to call your string prior to onCreate like this:

public static final String actnamefiletwo = "actnamebudtwo";

This is an example from my own app, hope it helps
