Question

我正在使用编译＆＃39; com.wdullaer：materialdatetimepicker：2.3.0＆＃39; 库来打开和关闭小时（AM＆amp; PM）。我想在用户选择AM之后再次为PM显示TimePickerDialog。然后，我想在TextView上显示AM + PM数据。这是One TimePickerDialog。

layout_time.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {
                Calendar now = Calendar.getInstance();
                TimePickerDialog tpd = TimePickerDialog.newInstance(
                        MainActivity.this,
                        now.get(Calendar.HOUR_OF_DAY),
                        now.get(Calendar.MINUTE),
                        false
                );
                tpd.show(getFragmentManager(), "Timepickerdialog");
            }
        });

@Override
    public void onResume() {
        super.onResume();
        TimePickerDialog tpd = (TimePickerDialog) getFragmentManager().findFragmentByTag("Timepickerdialog");
        if (tpd != null) tpd.setOnTimeSetListener(this);
    }

@Override
    public void onTimeSet(RadialPickerLayout view, int hourOfDay, int minute, int second) {
        String time = hourOfDay + ":" + minute + " am";
        txt_time.setText(time);
    }

Answer 1

显示第一个TimePicker方法中的第二个onTimeSet。

@Override
public void onTimeSet(RadialPickerLayout view, int hourOfDay, int minute, int second) {
    String time = hourOfDay + ":" + minute + " am";
    // call the second TimePicker's show() method from here
}

然后，当您同时拥有时，请设置第二个TextView的{{1}} TimePicker的{{1}}文字。

这样的事情：

onTimeSet

Answer 2

您必须在onTimeSet方法

中处理该条件

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

    if(amSelected){
       String amTime = hourOfDay + ":" + minute + " am";
      // call the second TimePicker's show() method from here
    }else if(pmSelected){
      String pmTime = hourOfDay + ":" + minute + " pm";
    }

    if(amSelected && pmSelected){
      //Set Data To textView
      yourtextView.setText(amTime +"-"+pmTime );
    }        

}
