Timepicker,timepickerdialog and Custom Timepicker (i)

Scene: Click on activity, Pop up a dialog, then click on the dialog button on the popup time. and Custom Dialog

Lazy, to use a choice of time requirements, only required hours and minutes, pop-up, the first time to think of Timepicker and Numberpicker,

First with Timepicker, found in 4.0 black ugly dead, 4.4 normal want and 5.0 is the pendulum, with

Timepickerdialog than timepicker many mornings and afternoons, forget it or customize it:

Very late, directly post code about the layout, etc. will be studied carefully after studying:

Main activity:

}

private void init () {
