小编use*_*048的帖子

我是Android的新手,我不知道如何使用sharedpreferences来检索存储的值,我找不到任何关于使用这些值在其他活动上编写的示例.如果有人可以帮助我,我会非常感激

这就是我存储数据的方式:

protected void onResume() {
    super.onResume();
    SharedPreferences prefs = getPreferences(0);
    String restoredText1 = prefs.getString("cpw", "30");
    if (restoredText1 != null) {
        savedcostperworker.setText(restoredText1, TextView.BufferType.EDITABLE);

        int selectionStart = prefs.getInt("selection-start", -1);
        int selectionEnd = prefs.getInt("selection-end", -1);
        if (selectionStart != -1 && selectionEnd != -1) {
            savedcostperworker.setSelection(selectionStart, selectionEnd);
        }
    }
}

protected void onPause() {
    super.onPause();
    SharedPreferences.Editor editor = getPreferences(0).edit();
    editor.putString("cpw", savedcostperworker.getText().toString());
    editor.putInt("selection-start", savedcostperworker.getSelectionStart());
    editor.putInt("selection-end", savedcostperworker.getSelectionEnd());
}

private EditText savedcostperworker;

现在我想在另一个活动的TextView中显示值"cpw",但我不知道如何
