从零开始的体温app开发（sharedPreferences）

if(sharedPreferences==null){
    sharedPreferences=getApplicationContext().getSharedPreferences("data", Context.MODE_PRIVATE);}

editText0.addTextChangedListener(new TextWatcher() {
    @Override
    public void beforeTextChanged(CharSequence s, int start, int count, int after) {

    }

    @Override
    public void onTextChanged(CharSequence s, int start, int before, int count) {

    }

    @Override
    public void afterTextChanged(Editable s) {
        SharedPreferences.Editor edit=sharedPreferences.edit();
        edit.putString("Name",editText0.getText().toString());
        edit.commit();
    }
});

public void initData(){
    if(sharedPreferences==null){
        sharedPreferences=getApplicationContext().getSharedPreferences("data", Context.MODE_PRIVATE);}
    editText0.setText(sharedPreferences.getString("name",""));
    editText5.setText(sharedPreferences.getString("num",""));
    editText6.setText(sharedPreferences.getString("cl",""));
