PickerUI

Android library to display a list of items for pick one with blur effect (if you wish). Support for Android 3.0 and up. It supports portrait and landscape mode, saving the state.

Try out the sample application on Google Play.

Demo

Including in Your Project

Last version is 1.0.1

Just add the following statement in your build.gradle

compile 'com.github.davidpizarro:pickerui:VERSION'

You may also add the library as an Android Library to your project. All the library files live in library.

Usage

To add the PickerUI to your layout add this to your xml

<com.dpizarro.uipicker.library.picker.PickerUI
        android:id="@+id/picker_ui_view"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"/>

You can add custom attributes in your xml to customize: background, colors, behaviors, elements, blur, blur effects...

<com.dpizarro.uipicker.library.picker.PickerUI
        android:id="@+id/picker_ui_view"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        pickerui:backgroundColor="#4cffa5"
        pickerui:linesCenterColor="#3941ff"
        pickerui:autoDismiss="true"
        pickerui:itemsClickables="true"
        pickerui:entries="@array/months"
        pickerui:textCenterColor="#000000"
        pickerui:textNoCenterColor="#737373"
        pickerui:blur="true"
        pickerui:blur_downScaleFactor="@integer/blur_downscale_min"
        pickerui:blur_FilterColor="#ff5e48"
        pickerui:blur_radius="@integer/blur_radius_min"
        pickerui:blur_use_renderscript="true"/>

Review attrs.xml file to know the list of shapes ready to be used in the library.

This configuration can be also provided programmatically. You can use PickerUI programatically, using the Builder class to set the settings and the desired functionalities of panel to make easy:

PickerUI mPickerUI = (PickerUI) findViewById(R.id.picker_ui_view);

List<String> options = Arrays.asList(getResources().getStringArray(R.array.months));

PickerUISettings pickerUISettings = new PickerUISettings.Builder()
                                                      .withItems(options)
                                                      .withBackgroundColor(getRandomColor())
                                                      .withAutoDismiss(true)
                                                      .withItemsClickables(false)
                                                      .withUseBlur(false)
                                                      .build();

mPickerUI.setSettings(pickerUISettings);

You can set/get values programatically:

mPickerUI.setItems(this, options);
mPickerUI.setColorTextCenter(R.color.background_picker);
mPickerUI.setColorTextNoCenter(R.color.background_picker);
mPickerUI.setBackgroundColorPanel(R.color.background_picker);
mPickerUI.setLinesColor(R.color.background_picker);
mPickerUI.setItemsClickables(false);
mPickerUI.setAutoDismiss(false);
mPickerUI.isPanelShown();

To slide (show/hide) PickerUI, you only have to use slide() method, selecting none (by default, center) or some position.

mPickerUI.slide();
//or
mPickerUI.slide(8);

In order to receive the value selected in the picker, you will need to implement the onItemClickPickerUI interface.

mPickerUI.setOnClickItemPickerUIListener(new PickerUI.PickerUIItemClickListener() {
                    @Override
                    public void onItemClickPickerUI(int which, int position, String valueResult) {
                        Toast.makeText(MainActivity.this, valueResult, Toast.LENGTH_SHORT).show();
                    }
                });

Or browse the source code of the sample application for a complete example of use.

Blur effect

This library applies a blur effect when you slide the picker, but it is optional and optimized. You can choose Java algorithm (slower) or RenderScript (a quick and efficient solution to blur images). Available since API 11 (Honeycomb), RenderScript allows to take advantage of the GPU acceleration and is targeted at high-performance 3D rendering and compute operations.

For the integration of the RenderScript support library you just have to add two lines to your build.gradle. You do not need to declare any dependencies. Depending on the gradle version you are running, the commands are slightly different:

1. Gradle version 0.14+ and newer

android {
    defaultConfig {
        renderscriptTargetApi 19
        renderscriptSupportModeEnabled true
    }
}

2. Older Gradle versions up to 0.13

android {
  defaultConfig {
      renderscriptTargetApi 19
      renderscriptSupportMode true
  }
}
