如何设置只有秒和小数的倒计时器？
例如:39(秒)、9(十进制)
这是我现在的代码!
public class MainActivity extends AppCompatActivity {
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
final Button timer = findViewById(R.id.countdown);
timer.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
// Timer for the text
new CountDownTimer(40000, 1000) {
public void onTick(long millisUntilFinished) {
final long decimal;
decimal = ?? // help me here
timer.setText("" + millisUntilFinished / 1000+ "." + decimal);
}
public void onFinish() {
timer.postDelayed(new Runnable() {
public void run() {
}
}, 10000);
}
}.start();
}
}); // end timer
}
非常感谢您的帮助!
最佳答案
new CountDownTimer(40000, 1) {
public void onTick(long millisUntilFinished) {
timer.setText("" + millisUntilFinished / 1000 + ":" + (millisUntilFinished % 1000) / 10 + " sec");
timer.setClickable(false);
}
public void onFinish() {
timer.postDelayed(new Runnable() {
public void run() {
}
}, 1000);
timer.setText("Start again");
timer.setClickable(true);
}
}.start();
}
}); // end timer
这应该可行，干得好!
