Question

I have dialog button and timepicker created in the same xml code below:

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="fill_parent"
    android:layout_height="fill_parent"
    android:orientation="vertical" >

    <TimePicker
        android:id="@+id/timePicker1"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content" />

        <LinearLayout android:id="@+id/LinearLayout02" android:layout_height="wrap_content" android:layout_width="fill_parent">
            <Button android:layout_height="wrap_content" android:id="@+id/dialog_ok" android:text="OK" android:layout_width="fill_parent" android:layout_weight="1"></Button>
            <Button android:layout_height="wrap_content" android:text="Cancel" android:id="@+id/dialog_cancel" android:layout_width="fill_parent" android:layout_weight="1"></Button>
        </LinearLayout>

</LinearLayout>

And then i created dialog in java code and also bring in the dialog and timepicker from xml code as showen below:

public void TimePickerDialog(){
    final Dialog dialog = new Dialog(this);

    dialog.setContentView(R.layout.sign_in_dialog);

/////////////////////updated code////////////////////
  TimePicker timePicker1 = (TimePicker) findViewById(R.id.timePicker1);

   timePicker1.setIs24HourView(true); 
/////////////////////////////////

    dialog.setTitle("Quick Mute");

    //Allow the dialog to be cancelable
    dialog.setCancelable(true);
    // Here we add functionality to our dialog box's content. In this example it's the two buttons
    //reference the button
    Button okButton = (Button) dialog.findViewById(R.id.dialog_ok);
    //Create a click listener
    okButton.setOnClickListener(new OnClickListener() {
         //override the onClick function to do something
         public void onClick(View v) {

         }
    });

    //reference the button
    Button cancelButton = (Button) dialog.findViewById(R.id.dialog_cancel);
    //Create a click listener
    cancelButton.setOnClickListener(new OnClickListener() {
         //override the onClick function to do something
         public void onClick(View v) {
          //Close the dialog</span>
                  dialog.dismiss();
        }
    });
    //finally show the dialog   
    dialog.show();
}

The problem i have is how do i get access to the timepicker that was created in xml code so that i can make the timepicker 24 hour timepicker? … and also how do i get the time from the timepicker that is in xml code?

Answer 1

Just like its usually done:

TimePicker timePicker = (TimePicker)dialog.findViewById(R.id.timePicker1);

and as usual this only works after dialog.setContentView is called. Then, to get the time picked, call:

timePicker.getCurrentHour();
timePicker.getCurrentMinute();
