In my previous post, I wrote about Android Date Picker class which I developed on my own. Now I’m gonna introduce another class which I developed to get Time from the client. Here we have a Dialog to get hour and minute from the user. This tutorial contains MyTimePicker.java class and dialog_set_time.xml file. As I said before, I need a custom and simple time picker. It will return time data by an Interface call back. Tried to make it too much simple to use and also I would be happy if you help me to improve it.
MyTimePicker.java
public class MyTimePicker {
Context context;
String hour = "00";
String minute = "00";
public MyTimePicker(final Context context) {
this.context = context;
}
public void showDialog(final OnDataReceive onDataReceive) {
final Dialog dialog = new Dialog(context);
dialog.requestWindowFeature(Window.FEATURE_NO_TITLE);
dialog.setCancelable(true);
dialog.setContentView(R.layout.dialog_set_time);
final EditText edtHour = dialog.findViewById(R.id.edtHour);
final EditText edtMinute = dialog.findViewById(R.id.edtMinute);
LinearLayout btnSave = dialog.findViewById(R.id.btnSave);
LinearLayout btnCancel = dialog.findViewById(R.id.btnCancel);
edtHour.addTextChangedListener(new TextWatcher() {
@Override
public void beforeTextChanged(CharSequence s, int start, int count, int after) {
}
@Override
public void onTextChanged(CharSequence s, int start, int before, int count) {
try {
if (Integer.parseInt(edtHour.getText().toString()) > 23) {
edtHour.setText(edtHour.getText().toString().substring(0, 1));
edtHour.setSelection(edtHour.getText().length());
Toast.makeText(context, "Invalid time!", Toast.LENGTH_SHORT).show();
} else {
if (edtHour.getText().toString().length() == 2) edtMinute.requestFocus();
}
} catch (Exception e) {
}
}
@Override
public void afterTextChanged(Editable s) {
}
});
edtMinute.addTextChangedListener(new TextWatcher() {
@Override
public void beforeTextChanged(CharSequence s, int start, int count, int after) {
}
@Override
public void onTextChanged(CharSequence s, int start, int before, int count) {
try {
if (Integer.parseInt(edtMinute.getText().toString()) > 59) {
edtMinute.setText(edtMinute.getText().toString().substring(0, 1));
edtMinute.setSelection(edtMinute.getText().length());
Toast.makeText(context, "Invalid time!", Toast.LENGTH_SHORT).show();
}
} catch (Exception e) {
}
}
@Override
public void afterTextChanged(Editable s) {
}
});
edtMinute.setOnEditorActionListener(new TextView.OnEditorActionListener() {
@Override
public boolean onEditorAction(TextView v, int actionId, KeyEvent event) {
if (actionId == EditorInfo.IME_ACTION_DONE) {
hour = String.format("%02d", Integer.parseInt(edtHour.getText().toString().trim()));
minute = String.format("%02d", Integer.parseInt(edtMinute.getText().toString().trim()));
onDataReceive.OnReceive(hour, minute);
dialog.dismiss();
}
return false;
}
});
btnSave.setOnClickListener(new View.OnClickListener() {
@Override

hour = String.format("%02d", Integer.parseInt(edtHour.getText().toString().trim()));

dialog.dismiss();
}
});
btnCancel.setOnClickListener(new View.OnClickListener() {

public void onClick(View v) {
dialog.dismiss();
}
});
dialog.getWindow().setSoftInputMode(WindowManager.LayoutParams.SOFT_INPUT_STATE_VISIBLE);
dialog.show();
}
public interface OnDataReceive {
void OnReceive(String hour, String minute);

Usage
MyTimePicker myTimePicker = new MyTimePicker(MainActivity.this);
myTimePicker.showDialog(new MyTimePicker.OnDataReceive() {
@Override
public void OnReceive(String hour, String minute) {
Toast.makeText(MainActivity.this,"Hour: "+hour+" and Minute: "+minute,Toast.LENGTH_SHORT).show();
}
});
