Ich habe folgenden Code von developer.android.com
1new CountdownTimer(30000, 1000) {
2
3 public void onTick(long millisUntilFinished) {
4 mTextField.setText("seconds remaining: " + millisUntilFinished / 1000);
5 }
6
7 public void onFinish() {
8 mTextField.setText("done!");
9 }
10 }.start();
2
3 public void onTick(long millisUntilFinished) {
4 mTextField.setText("seconds remaining: " + millisUntilFinished / 1000);
5 }
6
7 public void onFinish() {
8 mTextField.setText("done!");
9 }
10 }.start();
Er soll einen simplen Countdown in einem Textfeld zeigen.
So weit so gut, wenn ich diesen Code allerdings in Eclipse einfüge zeigt er mir gewisse Fehler an.
1package countdown.test;
2
3import android.app.Activity;
4import android.os.Bundle;
5
6public class test extends Activity {
7 /** Called when the activity is first created. */
8 @Override
9 public void onCreate(Bundle savedInstanceState) {
10 super.onCreate(savedInstanceState);
11 new CountdownTimer(30000, 1000) {
12
13 public void onTick(long millisUntilFinished) {
14 mTextField.setText("seconds remaining: " + millisUntilFinished / 1000);
15 }
16
17 public void onFinish() {
18 mTextField.setText("done!");
19 }
20 }.start();
21
22 }
23}
2
3import android.app.Activity;
4import android.os.Bundle;
5
6public class test extends Activity {
7 /** Called when the activity is first created. */
8 @Override
9 public void onCreate(Bundle savedInstanceState) {
10 super.onCreate(savedInstanceState);
11 new CountdownTimer(30000, 1000) {
12
13 public void onTick(long millisUntilFinished) {
14 mTextField.setText("seconds remaining: " + millisUntilFinished / 1000);
15 }
16
17 public void onFinish() {
18 mTextField.setText("done!");
19 }
20 }.start();
21
22 }
23}
So sieht mein Code aus.
Der Fehler:
CountDownTimer cannot be resolved to a type test.java /Countdown21/src/countdown/test line 11 Java Problem
Wenn ich "Change to CountDownTimer (android.os)" auswähle, stellt er dies zwar richtig, zeigt aber gleich zwei neue Fehler an.
Undzwar bei den Textfeldern...
...ich verzweifel...
