Different Android selectors are easy to use and address date and time are easy to use !, Android Selector

Preface

Picker is used in many cases in Android development, such as selecting the address, date, and time.

 

Native Picker and iOS-like Picker both move up and down or left to a fixed area to choose options:

The number of displays is small. If the current option is far away from the required option, it will be slide many times;

Sliding is difficult to control. It is annoying to slide slowly back to the opposite direction if you are not careful.

 

The GridPicker in ZBLibrary displays multiple rows and multiple columns on each page, greatly increasing the number of displays. The sliding option is changed to click selection, which greatly improves the operation precision.

 

I. Native Picker

 

Problem:

1.The number of options displayed in the address and time selector is small.Switch only one by one, with low efficiency.

2. to select a year for the date selector, You need to click the text of the year at the top of the page. It is not easy for your fingers to reach, and few options are displayed;

Select the month and click the left arrow or the right arrow to slide. Only one switch is allowed.Low Efficiency.

 

 

Ii. iOS-like Picker

 

Problem:

1.The number of displayed options is small..

2. The option can only be switched one by one.

3. RequiredSlide up or down to the specified box,Difficult to control. 

 

 

Iii. ZBLibrary GridPicker

The Gif image below looks like a card, but the mobile phone actually runs smoothly.

 

All operations are on the lower half of the screen,OperationEasy;

Multiple rows and multiple columns are displayed on each page, which greatly increases the display quantity;

Change the sliding selection to click selection, which greatly improves the operation accuracy.

 

ZBLibrary GridPickerSolved all the above problems perfectly!

2. Open the corresponding Activity and pass the value

Take the date selector DatePickerWindow as an example:

 

You can open and pass the value in this way.

toActivity(DatePickerWindow.createIntent(context, new int[]{1971, 0, 1}            , TimeUtil.getDateDetail(System.currentTimeMillis())), 1000, false);

ToActivity is the method in BaseActivity in ZBLibrary. It can be changed to startActivityForResult.

 

3. Receive returned results in onActivityResult

@ Override public void onActivityResult (int requestCode, int resultCode, Intent data) {super. onActivityResult (requestCode, resultCode, data); if (resultCode! = RESULT_ OK) {return;} switch (requestCode) {case 1000: if (data! = Null) {ArrayList <Integer> list = data. getIntegerArrayListExtra (DatePickerWindow. RESULT_DATE_DETAIL_LIST); if (list! = Null & list. size ()> = 3) {show1_toast ("date selected" + list. get (0) + "-" + (list. get (1) + 1) + "-" + list. get (2) ;}} break; default: break ;}}

 

Okay.

If you are too reluctant to perform the steps 2-3, copy, paste, and rename DemoMainActivity. java in ZBLibrary, and change the code!

 

 

In fact, the address, date, and time selectors in ZBLibrary use GridPickerView to control the display and operation,

You can also use GridPickerView to implement selector for other purposes.
