        case R.id.botoAbdominals:

            alarm_manager2.set(AlarmManager.RTC_WAKEUP, calendar2.getTimeInMillis(),
                    pending_intent1);
            break;

    }
}

@Override
protected Dialog onCreateDialog(int id) {
    if (id == DIALOG_ID)

        return new TimePickerDialog(Main2Activity.this, kTimePickerListener, hour_x, minute_x, true);
    return null;
}

protected TimePickerDialog.OnTimeSetListener kTimePickerListener =
        new TimePickerDialog.OnTimeSetListener() {
            @Override
            public void onTimeSet(TimePicker view, int hourOfDay, int minute) {
                hour_x = hourOfDay;
                minute_x = minute;
                Toast.makeText(Main2Activity.this, hour_x + ": " + minute_x, Toast.LENGTH_LONG).show();
            }
        };

下面是我的xml：

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:weightSum="2"
android:orientation="horizontal"
android:theme="@android:style/Theme.Black.NoTitleBar.Fullscreen" >

<ImageButton
    android:layout_width="0dp"
    android:layout_height="400dp"
    android:layout_weight="1"
    android:id="@+id/botoAbdominals"
    android:background="@drawable/abdominals"
    android:contentDescription="ImatgeAbdominals"
    android:layout_marginTop="50dp"
    android:layout_marginRight="10dp"
    android:layout_marginLeft="10dp"
    />


<ImageButton
    android:layout_width="0dp"
    android:layout_height="400dp"
    android:layout_weight="1"
    android:id="@+id/botoFlexio"
    android:layout_gravity="top"
    android:layout_marginTop="50dp"

    android:layout_marginRight="10dp"
