使用共享首选项从一个更改TextView中保存多个值？

Question

我有一个textView值，可以使用加号和减号按钮更改。 （比如机器人编号选择器对象，但是自定义。）

我需要能够提取每个值并保存，具体取决于用户设置的微调器值。

对于为每个微调器位置保存的每个值，当用户返回微调器上的相同位置时，将显示输入的先前值，表示已输入值。

For Instance :(如果微调器是星期几）（值是TextView /自定义微调器）“如果用户选择星期三，并选择值7，则转到星期一并选择8，如果用户返回到星期三之前输入的值（7）将显示，如果用户返回星期一，则将显示值8。

Spinner代码

final Spinner spinner1 = (Spinner) findViewById(R.id.sp_dotw);
final ArrayAdapter<CharSequence> adapter =    
        ArrayAdapter.createFromResource(this, R.array.dotw_array, R.layout.custom_spinner);
adapter.setDropDownViewResource(android.R.layout.simple_spinner_dropdown_item);

spinner1.setAdapter(adapter);
spinner1.setOnItemSelectedListener(new OnItemSelectedListener() {
    public void onItemSelected(AdapterView<?> parent, View view, int position, long id) {
        spinner1position = position;
        spinnerPos();
        showToast("spinnerdotw: position= " + position + "id=" + id);
    }

    public void onNothingSelected(AdapterView<?> adapterView) {
        showToast("No Dotw selected");
    }
});

号码选择器代码

@Override
public void onClick(View v) {
    String getString = String.valueOf(tvSony.getText());
    int current1 = Integer.parseInt(getString);

    if (v == btnUp1) {
        if (current1 < nEnd) {
            current1++;
            tvSony.setText(String.valueOf(current1));
        }
    }

    if (v == btnDown1) {
        if (current1 > nStart) {
            current1--;
            tvSony.setText(String.valueOf(current1));
        }
    }

    sonyRs = current1;
}

有关如何做到这一点的任何建议都会受到高度赞赏吗？

到目前为止我的尝试：

    SharedPreferences sp = getSharedPreferences("sun32save", MODE_PRIVATE);
    SharedPreferences.Editor spedit = sp.edit();

    if (spinner1position == 0 & spinner2position == 0) {

        spedit.putString("sun32Son", String.valueOf(sonyRs));


        String savedValue1 = sp.getString("sun32Son", "");
        spedit.commit();

        tvSony.setText(savedValue1);

    }


            //if a value is found, display value
    if (spinner1position == 0 & spinner2position == 1) {

        spedit.putString("sun35Son", String.valueOf(sonyRs));


        String savedValue2 = sp.getString("sun35Son", "");
        spedit.commit();

        tvSony.setText(savedValue2);

如果我返回到相同的微调器位置，则返回默认值0。
