timepicker selected value text size [duplicate]

This question already has an answer here:
Implement iOS like time picker in Android
(1 answer)
Closed 5 years ago.
I want to change the selected text value size of a time picker.
Do we have any libraries for the same?
As I searched we do not have any customization in android. Need to develop a UI similar to iOS time picker.

For android brucetoo/PickView similar to IOS,
This is a helper lib for us to pick date or province like IOS system WheelView widget.
Added feature to pick time with WheelView Widget
Dependencies
compile 'com.brucetoo.pickview:library:1.2.3'
to use
DatePickerPopWin pickerPopWin = new DatePickerPopWin.Builder(MainActivity.this, new DatePickerPopWin.OnDatePickedListener() {
#Override
public void onDatePickCompleted(int year, int month, int day, String dateDesc) {
Toast.makeText(MainActivity.this, dateDesc, Toast.LENGTH_SHORT).show();
}
}).textConfirm("CONFIRM") //text of confirm button
.textCancel("CANCEL") //text of cancel button
.btnTextSize(16) // button text size
.viewTextSize(25) // pick view text size
.colorCancel(Color.parseColor("#999999")) //color of cancel button
.colorConfirm(Color.parseColor("#009900"))//color of confirm button
.minYear(1990) //min year in loop
.maxYear(2550) // max year in loop
.showDayMonthYear(true) // shows like dd mm yyyy (default is false)
.dateChose("2013-11-11") // date chose when init popwindow
.build();

How to set font size for items in Xamarin Picker?

I try to change the items font size in Xamarin.Picker for my Android app. In my project, I use BindablePicker that inherits from Picker class. Source here.
I spent some time to do research and I found that I should create a PickerRenderer class and render the Picker.
My renderer class:
public class BindablePickerRenderer : PickerRenderer
{
protected override void OnElementChanged(ElementChangedEventArgs<Picker> e)
{
base.OnElementChanged(e);
var picker = e.NewElement;
BindablePicker bp = (BindablePicker)this.Element;
if (this.Control != null)
{
var pickerStyle = new Style(typeof(BindablePicker))
{
Setters =
{
new Setter { Property = VisualElement.BackgroundColorProperty, Value = Color.Red }
}
};
picker.Style = pickerStyle;
}
}
}
For test purposes I set the backgroundColor for Picker and it works fine. However, in my PickerRenderer class I only have access to Control property which is type of Android.Widget.EditText.
The effect :
Question
How can I access to Picker items, and set the font size for them? Is this possible?
Here is my repository with an example project.

Font size in Picker control in xamarin forms

I has been able to resolve this by add the line:
Control.TextSize = 30;
On OnElementChanged method:
public class BindablePickerRenderer : PickerRenderer
{
protected override void OnElementChanged(ElementChangedEventArgs<Picker> e)
{
base.OnElementChanged(e);
if (this.Control != null)
{
Control.TextSize = 30;
}
}
}
Maybe this can help someone that is looking for change font size of a Bindable picker.

After some research I don't think this is possible for a generic picker.
You would likely have an easier time just rolling your own picker control in Forms code using a clickable label that pops up a list to select from.
I was able to style a date or time picker using styles in the Android styles.xml file, but since Android does not have a built in generic picker widget, I imagine that Forms is rolling it's own picker list as I can't find the dialog widget to theme that changes your list text size.
For a DatePicker, I can just add the following to the main style element in styles.xml:
<item name="android:datePickerDialogTheme">#style/AppCompatDialogStyle</item>
and then add a new style element in style.xml
<style name="AppCompatDialogStyle" parent="Theme.AppCompat.Light.Dialog">
<item name="android:textSize">60sp</item>
</style>
The above does change the text size for a DatePicker (no custom renderer required). Also the customer picker renderer is a bit of a misnomer... it really is just rendering the edit text field that shows the picked item, and allows opening the picker list on click.
I know this is not a solution, but just an indication as to what I found when checking this out and a suggestion that it is likely easiest to not use the Forms Picker type if you want such customization.

new DatePickerDialog(getContext(), AlertDialog.THEME_HOLO_LIGHT, null, 2016, 9, 18);
but the above code is not work on Android N device, it always show the calander mode, is there something different in Android N? How can I instance a spinner mode datepicker dialog?

Getting Memory Out For using color picker

I am getting Memory out error in Bitmap for one of my Play Store Apps. In this app I used color Picker for choosing color by User. And that gives me the error.
My used color Picker is:
https://github.com/chiralcode/Android-Color-Picker
Its normally take 6 to 7 MB memory.
Now I can't solve this problem. Is there any better Color Picker?
Thanks in advance.

If you're looking for a great new android color picker that use material design I have forked an great project from github and made a simple-to-use android color picker dialog.
This is the project: Android Color Picker
HOW TO USE IT
Adding the library to your project
The aar artifact is available at the jcenter repository. Declare the repository and the
dependency in your build.gradle.
(root)
repositories {
jcenter()
}
(module)
dependencies {
compile 'com.pes.materialcolorpicker:library:1.0.1'
}
Use the library
Create a color picker dialog object
final ColorPicker cp = new ColorPicker(MainActivity.this, defaultColorR, defaultColorG, defaultColorB);
defaultColorR, defaultColorG, defaultColorB are 3 integer ( value 0-255) for the initialization of the color picker with your custom color value. If you don't want to start with a color set them to 0 or use only the first argument
Then show the dialog (when & where you want) and save the selected color
/* Show color picker dialog */
cp.show();
/* On Click listener for the dialog, when the user select the color */
Button okColor = (Button)cp.findViewById(R.id.okColorButton);
okColor.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
/* You can get single channel (value 0-255) */
selectedColorR = cp.getRed();
selectedColorG = cp.getGreen();
selectedColorB = cp.getBlue();
/* Or the android RGB Color (see the android Color class reference) */
selectedColorRGB = cp.getColor();
cp.dismiss();
}
});
That's all :)
