我创建了一个微调器,我想在关闭应用程序时保存所有微调器输入。我能怎么做?我认为共享偏好可以帮助我,但我不知道如何使用它!这是我的代码:
private Spinner spinner;
private EditText Text;
private ArrayAdapter<String> adapter;
private Button addButton;
public void onCreate(Bundle savedInstanceState)
{
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
Text = (EditText) findViewById(R.id.et);
final List<String> planets = new ArrayList<String>(Arrays.asList(getResources().getStringArray(R.array.clienti_arrays)));
adapter = new ArrayAdapter<String>(this, android.R.layout.simple_spinner_item, planets);
adapter.setDropDownViewResource(android.R.layout.simple_spinner_dropdown_item);
spinner = (Spinner) findViewById(R.id.spinner1);
spinner.setAdapter(adapter);
addButton = (Button) findViewById(R.id.add_new);
addButton.setOnClickListener(new OnClickListener()
{
public void onClick(View v)
{
addNewSpinnerItem();
Collections.sort(planets);
}
});
}
protected void addNewSpinnerItem()
{
String textHolder = "" + Text.getText().toString();
adapter.add(textHolder);
}
public int compare(String s1, String s2) { return s1.toLowerCase().compareTo(s2.toLowerCase());
}
}
非常感谢你的帮助..
