hey I am trying to make a TimepickerDialog. But the app crashes soon as I press the Set Time button. Here is the code.<\/p>\n
MainActivity:<\/p>\n
package com.wifitimer;\nimport java.text.DateFormat;\nimport java.util.Calendar;\nimport android.app.Activity;\nimport android.app.TimePickerDialog;\nimport android.os.Bundle;\nimport android.widget.TimePicker;\n\npublic class MainActivity extends Activity {\nDateFormat formatDateTime=DateFormat.getDateTimeInstance();\nCalendar dateTime=Calendar.getInstance();\n\n@Override\npublic void onCreate(Bundle savedInstanceState) {\n super.onCreate(savedInstanceState);\n setContentView(R.layout.activity_main);\n}\n\npublic void chooseTime(){\n new TimePickerDialog(this, t, dateTime.get(Calendar.HOUR_OF_DAY), dateTime.get(Calendar.MINUTE), true).show();\n}\n\nTimePickerDialog.OnTimeSetListener t = new TimePickerDialog.OnTimeSetListener() {\n @Override\n public void onTimeSet(TimePicker view, int hourOfDay, int minute) {\n dateTime.set(Calendar.HOUR_OF_DAY, hourOfDay);\n dateTime.set(Calendar.MINUTE,minute);\n }\n};\n}\n<\/code><\/pre>\nAm I missing some permissions or anything?<\/p>\n
Here is the logcat as requested:<\/p>\n

I think you are calling chooseTime() from your xml layout file onClick attribute you need to change method signature to this<\/p>\n
public void chooseTime(View view){\n\n new TimePickerDialog(this, t, dateTime.get(Calendar.HOUR_OF_DAY), dateTime.get(Calendar.MINUTE), true).show();\n\n}\n<\/code><\/pre>\n<\/li>\n- \n
change method like<\/p>\n
public void chooseTime(View view){\n new TimePickerDialog(this, t, dateTime.get(Calendar.HOUR_OF_DAY), dateTime.get(Calendar.MINUTE), true).show();\n}\n<\/code><\/pre>\nand in You xml Control<\/code> Like<\/p>\n \n<\/code><\/pre>\n<\/li>\n- \n
