java如何在安卓中一个接一个地运行计时器？
如何一个接一个地运行计时器？ 例如：我使用两个编辑文本和一个按钮， 在将2 edittext输入为1和2（以分钟为单位）后，计时器应首先完成第一个给定输入，然后开始第二个输入。 然后，当我单击StopTimer时，它应该停止并显示edittext输入和停止的计时器值。 但它只适用于第一次输入。。但第二次输入失败。 这是我试过的代码
public class MainActivity extends Activity implements OnClickListener {
private Button buttonStartTime, buttonStopTime;
private EditText edtTimerValue;
private EditText edtTimerValue1;
private TextView textViewShowTime; // will show the time
private TextView textViewShowTime1; // will show the time
private CountDownTimer countDownTimer; // built in 安卓 class
private CountDownTimer countDownTimer1; // built in 安卓 class
// CountDownTimer
private long totalTimeCountInMilliseconds; // total count down time in
private long totalTimeCountInMilliseconds1;
// milliseconds
private long timeBlinkInMilliseconds; // start time of start blinking
private long timeBlinkInMilliseconds1;
private boolean blink; // controls the blinking .. on and off
private boolean blink1;
/** Called when the activity is first created. */
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
buttonStartTime = (Button) findViewById(R.id.btnStartTime);
buttonStopTime = (Button) findViewById(R.id.btnStopTime);
textViewShowTime = (TextView) findViewById(R.id.tvTimeCount);
edtTimerValue = (EditText) findViewById(R.id.edtTimerValue);
buttonStartTime.setOnClickListener(this);
buttonStopTime.setOnClickListener(this);
textViewShowTime1 = (TextView) findViewById(R.id.tvTimeCount1);
edtTimerValue1 = (EditText) findViewById(R.id.edtTimerValue2);
}
@Override
public void onClick(View v) {
if (v.getId() == R.id.btnStartTime) {
textViewShowTime.setTextSize(15);
setTimer();
buttonStopTime.setVisibility(View.VISIBLE);
buttonStartTime.setVisibility(View.GONE);
edtTimerValue.setVisibility(View.GONE);
edtTimerValue.setText("");
startTimer();
} else if (v.getId() == R.id.btnStopTime) {
countDownTimer.cancel();
if(countDownTimer1!=null) {
countDownTimer1.cancel();
}
buttonStartTime.setVisibility(View.VISIBLE);
buttonStopTime.setVisibility(View.GONE);
edtTimerValue.setVisibility(View.VISIBLE);
}
}
private void setTimer() {
int time = 0;
if (!edtTimerValue.getText().toString().equals("")) {
time = Integer.parseInt(edtTimerValue.getText().toString());
} else
Toast.makeText(MainActivity.this, "Please Enter Minutes...",
Toast.LENGTH_LONG).show();
totalTimeCountInMilliseconds = 60 * time * 1000;
timeBlinkInMilliseconds = 30 * 1000;
}
private void startTimer() {
countDownTimer = new CountDownTimer(totalTimeCountInMilliseconds, 500) {
@Override
public void onTick(long leftTimeInMilliseconds) {
long seconds = leftTimeInMilliseconds / 1000;
if (leftTimeInMilliseconds < timeBlinkInMilliseconds) {
if (blink) {
textViewShowTime.setVisibility(View.VISIBLE);
} else {
textViewShowTime.setVisibility(View.INVISIBLE);
}
blink = !blink; // toggle the value of blink
}
textViewShowTime.setText(String.format("%02d", seconds / 60)
+ ":" + String.format("%02d", seconds % 60));
}
@Override
public void onFinish() {
// this function will be called when the timecount is finished
textViewShowTime.setText("Time up!");
textViewShowTime.setVisibility(View.VISIBLE);
buttonStartTime.setVisibility(View.VISIBLE);
buttonStopTime.setVisibility(View.GONE);
edtTimerValue.setVisibility(View.VISIBLE);
setTimer1(); //here i am using two call the second input
startTimer1(); //here i am using to start the second input automatically.
}
}.start();
}
//this is not working..
private void setTimer1() {
Log.e("text","tesxt");
int time = 0;
if (!edtTimerValue1.getText().toString().equals("")) {
time = Integer.parseInt(edtTimerValue1.getText().toString());
} else
Toast.makeText(MainActivity.this, "Please Enter Minutes...",
Toast.LENGTH_LONG).show();
totalTimeCountInMilliseconds1 = 60 * time * 1000;
timeBlinkInMilliseconds1 = 30 * 1000;
}
//this function is also not working to start the second input..
private void startTimer1() {
Log.e("time","time");
countDownTimer1 = new CountDownTimer(timeBlinkInMilliseconds1, 500) {
@Override
public void onTick(long millisUntilFinished) {
long seconds = millisUntilFinished / 1000;
if (millisUntilFinished < timeBlinkInMilliseconds) {
if (blink1) {
textViewShowTime1.setVisibility(View.VISIBLE);
} else {
textViewShowTime1.setVisibility(View.INVISIBLE);
}
blink1 = !blink1;
}
textViewShowTime1.setText(String.format("%02d", seconds / 60)
+ ":" + String.format("%02d", seconds % 60));
}
@Override
public void onFinish() {
textViewShowTime1.setText("Time up!");
textViewShowTime1.setVisibility(View.VISIBLE);
edtTimerValue1.setVisibility(View.VISIBLE);
}
}.start();
}
}
布局是这样的
