How to convert input type [closed]

Tags: ,



I am making timer when user set time and when I want to set time in second “mm:ss”(minutes:seconds) formula my app stops becouse app doesn’t accept colon. So how to convert input type from “mm:ss” to “mmss” that the textview image does not change but in the program changed to the format as I mentioned above

here is my code `

    mEditTextInput = (EditText) findViewById(R.id.editText);
    btn1 = (Button) findViewById(R.id.button);
    mButtonSet=findViewById(R.id.button_set);
    mTextViewCountDown = findViewById(R.id.textView);


    mButtonSet.setOnClickListener(new View.OnClickListener() {




        @Override
        public void onClick(View v) {
            String input = mEditTextInput.getText().toString();

           public long getTimeInLong(String input) {
                StringBuilder builder = new StringBuilder();
                String[] splittedString = input.split(":");
                builder.append(splittedString[0]);
                builder.append(splittedString[1]);

                return Long.parseLong(builder.toString());
            }



            setTime(millisInput);
            mEditTextInput.setText("%02d%02d");


        }
    });





    btn1.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View v) {
            mCountDownTimer=new CountDownTimer(mTimeLeftInMillis,1000) {
                @Override
                public void onTick(long millisUntilFinished) {
                    mTimeLeftInMillis=millisUntilFinished;
                    updateCountDownText();

                }

                @Override
                public void onFinish() {

                }
            }.start();
        }
    });

    updateCountDownText();


}

private void updateCountDownText(){
    int hours = (int) (mTimeLeftInMillis / 1000) / 3600;
    int minutes = (int) ((mTimeLeftInMillis / 1000) % 3600) / 60;
    int seconds = (int) (mTimeLeftInMillis / 1000) % 60;
    String timeLeftFormatted;

        timeLeftFormatted = String.format(Locale.getDefault(),
                "%02d:%02d", minutes, seconds);

    mTextViewCountDown.setText(timeLeftFormatted);

}
private void setTime(long milliseconds) {
    resetTimer();

    mStartTimeInMillis = milliseconds;

}
private void resetTimer() {
    mTimeLeftInMillis = mStartTimeInMillis;
    updateCountDownText();
}


public void decrease2Integer(View view) {
    if (czas2 >=5) {
        czas2 = czas2 - 5;
        display3(czas2);
    }

}


public void increase2Integer(View view) {
    czas2 = czas2 + 5;
    display3(czas2);
}
private void display3(int time2) {
    TextView display3Integer = (EditText) findViewById(R.id.editText);
    String formattedTime1 =String.format( "%02d:%02d", time2 / 60, time2 % 60);




    display3Integer.setText(formattedTime1);

}

Answer

For the string to be parseable as long, it must not contain special characters like ":" . A function to convert the time containing “:” to long may look like this :

public long getMillisTimeInLong(String timeInMinsSecsWithColon) {
    String[] splittedString = timeWithColon.split(":");
    int min = Integer.parseInt(splittedString[0]);
    int sec = Integer.parseInt(splittedString[1]);
    return min*60*1000 + sec*1000;
}

EDIT: Taking @Joakim Danielson’s comment into consideration, the function is modified as above.
