Nohnkhumr:
Je suis en train de mettre en place un compte à rebours à l' aide gestionnaire dans une vue de texte simple. Je dois définir un temps personnalisé. par ex ., la minuterie doit commencer à partir de 06:12:00 .
- Ceci est le MainActivityenter code here
Code -.
public class MainActivity extends AppCompatActivity {
private Button startButton;
private Button pauseButton;
private TextView timerValue;
private long startTime = 0L;
private Handler customHandler = new Handler();
long timeInMilliseconds = 0L;
long timeSwapBuff = 0L;
long updatedTime = 0L;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
timerValue = (TextView) findViewById(R.id.timerValue);
startButton = (Button) findViewById(R.id.startButton);
--listener bouton de démarrage -
startButton.setOnClickListener(new View.OnClickListener() {
public void onClick(View view) {
startTime = SystemClock.uptimeMillis();
customHandler.postDelayed(updateTimerThread, 0);
}
});
pauseButton = (Button) findViewById(R.id.pauseButton);
--listener pour pause button--
pauseButton.setOnClickListener(new View.OnClickListener() {
public void onClick(View view) {
timeSwapBuff += timeInMilliseconds;
customHandler.removeCallbacks(updateTimerThread);
}
});
}
private Runnable updateTimerThread = new Runnable() {
public void run()
{
timeInMilliseconds = SystemClock.uptimeMillis() - startTime;
updatedTime = timeSwapBuff + timeInMilliseconds;
int secs = (int) (updatedTime / 1000);
int mins = secs / 60;
int hours = mins/60;
secs = secs % 60;
timerValue.setText(String.format("%02d", hours)+":" +
(String.format("%02d", mins)) + ":"
+ String.format("%02d", secs) );
customHandler.postDelayed(this, 0);
}
};}
La sortie je reçois est ici https://ibb.co/pd95Yww
