我正在尝试在我的preferenceActivity中打印editText的值，为此我正在使用自定义DialogPreference，因此用户可以输入要过滤的价格，当他单击“确定”时，它应该在活动中打印过滤后的价格. 但是当我单击“确定”时，它什么也没显示，我错过了什么？
public class MyDialogShow extends DialogPreference {
private View view;
private EditText maximo;
private EditText minimo;
private TextView valores;
private Context context;
private View v;
@Override
protected View onCreateDialogView() {
// TODO Auto-generated method stub
view= super.onCreateDialogView();
LayoutInflater inflater = LayoutInflater.from(getContext());
v = inflater.inflate(R.layout.pref_valor, null);
valores = (TextView) v.findViewById(R.id.escolhaValor);
minimo = (EditText) view.findViewById(R.id.minimo);
minimo.addTextChangedListener(new TextWatcher() {
boolean isEdiging;
private String current = "";
@Override
public void onTextChanged(CharSequence s, int start, int before, int count) {
}
@Override
public void beforeTextChanged(CharSequence s, int start, int count, int after) {
}
@Override
public void afterTextChanged(Editable s) {
if (!s.toString().equals(current)) {
minimo.removeTextChangedListener(this);
String replaceable = String.format("[%s,.\\s]", NumberFormat.getCurrencyInstance().getCurrency().getSymbol());
String cleanString = s.toString().replaceAll(replaceable, "");
double parsed;
try {
parsed = Double.parseDouble(cleanString);
} catch (NumberFormatException e) {
parsed = 0.00;
}
String formatted = NumberFormat.getCurrencyInstance().format((parsed/100));
current = formatted;
minimo.setText(formatted);
minimo.setSelection(formatted.length());
minimo.addTextChangedListener(this);
}
}
});
