java - StartTimePicker 设置时间(android)

Question

抱歉我的英语不好。我想要如果单击 textView 打开对话框并设置时间(24 小时)，但我无法获取值。 Log.e 不输出任何内容

time.setOnClickListener(new OnClickListener() {
            @SuppressLint("NewApi") @Override
            public void onClick(View v) {
                DialogFragment dialogFragment = new StartTimePicker();
                dialogFragment.show(getFragmentManager(), "start_t_picker");
            }
        });

//code
@SuppressLint("NewApi") 
        class StartTimePicker extends DialogFragment implements OnTimeSetListener{

            @Override
            public Dialog onCreateDialog(Bundle savedInstanceState) {
                TimePickerDialog dialog = new TimePickerDialog(Send.this, null, hour, min, true);

                return dialog;
            }


            @Override
            public void onTimeSet(TimePicker view, int hourOfDay, int minute) {

                Log.e("time is", String.valueOf(hourOfDay) + ":" + String.valueOf(minute));

            }
        } 

Answer 1

像这样更改你的 onCreateDialog() 方法

            @Override
            public Dialog onCreateDialog(Bundle savedInstanceState) {
                TimePickerDialog dialog = new TimePickerDialog(Send.this, this, hour, min, true);

                return dialog;
            }
