나는 간단한 텍스트보기 핸들러를 사용하여 타이머 다운 카운트를 구현하기 위해 노력 해왔다. 나는 사용자 정의 시간을 설정해야합니다. 전을 위해 . 타이머가에서 시작해야 6시 12분 0초 .
- 이것은이다 MainActivity의enter code here 코드 -.
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);
시작 버튼 --listener -
startButton.setOnClickListener(new View.OnClickListener() {
public void onClick(View view) {
startTime = SystemClock.uptimeMillis();
customHandler.postDelayed(updateTimerThread, 0);
}
});
pauseButton = (Button) findViewById(R.id.pauseButton);
--listener 일시 정지에 대한 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);
}
};}
내가 무엇입니까 출력은 여기 https://ibb.co/pd95Yww
