Timepicker in Preferencescreen

TimePicker in PreferenceScreen

There is no TimePreference built into Android. However, creating your own is fairly easy. Here's one I did:

import android.content.Context;
import android.content.res.TypedArray;
import android.preference.DialogPreference;
import android.util.AttributeSet;
import android.view.View;
import android.widget.TimePicker;

public class TimePreference extends DialogPreference {
    private int lastHour=0;
    private int lastMinute=0;
    private TimePicker picker=null;

    public static int getHour(String time) {
        String[] pieces=time.split(":");

        return(Integer.parseInt(pieces[0]));
    }

    public static int getMinute(String time) {
        String[] pieces=time.split(":");

        return(Integer.parseInt(pieces[1]));
    }

    public TimePreference(Context ctxt, AttributeSet attrs) {
        super(ctxt, attrs);

        setPositiveButtonText("Set");
        setNegativeButtonText("Cancel");
    }

    @Override
    protected View onCreateDialogView() {
        picker=new TimePicker(getContext());

        return(picker);
    }

    @Override
    protected void onBindDialogView(View v) {
        super.onBindDialogView(v);

        picker.setCurrentHour(lastHour);
        picker.setCurrentMinute(lastMinute);
    }

    @Override
    protected void onDialogClosed(boolean positiveResult) {
        super.onDialogClosed(positiveResult);

        if (positiveResult) {
            lastHour=picker.getCurrentHour();
            lastMinute=picker.getCurrentMinute();

            String time=String.valueOf(lastHour)+":"+String.valueOf(lastMinute);

            if (callChangeListener(time)) {
                persistString(time);
            }
        }
    }

    @Override
    protected Object onGetDefaultValue(TypedArray a, int index) {
        return(a.getString(index));
    }

    @Override
    protected void onSetInitialValue(boolean restoreValue, Object defaultValue) {
        String time=null;

        if (restoreValue) {
            if (defaultValue==null) {
                time=getPersistedString("00:00");
            }
            else {
                time=getPersistedString(defaultValue.toString());
            }
        }
        else {
            time=defaultValue.toString();
        }

        lastHour=getHour(time);
        lastMinute=getMinute(time);
    }
}

Android: TimePicker in PreferenceScreen: send data to the TimePicker

You can create custom preference with additional attributes, in your case with limit attribute.

res/values/attrs.xml

<declare-styleable name="CustomPreference">
    <attr name="limit" format="integer"/>
</declare-styleable>

CustomPreference.java

public class CustomPreference extends DialogPreference {
private int limit;

public CustomPreference(Context context, AttributeSet attrs) {
    super(context, attrs);

    TypedArray a = context.obtainStyledAttributes(attrs, R.styleable.CustomPreference, 0, 0);
    limit = a.getInteger(R.styleable.CustomPreference_limit, 0);

    a.recycle();
}

In preference layout:

<PreferenceScreen xmlns:android="http://schemas.android.com/apk/res/android" 
   xmlns:app="http://schemas.android.com/apk/res/com.example.package">
    <PreferenceCategory>
        <com.example.package.CustomPreference
        android:key="@string/pref_key"
            android:title="@string/pref_title"
            app:limit="6" />
    </PreferenceCategory>
</PreferenceScreen>

Also you can set an attribute value programmatically

How to get time from timepicker dialog to preference activity?

Try this below code I used code and checked,the newValue you will get is the time you selected from time preference dialog.

 Preference preference = getPreferenceManager().findPreference("timePrefA_Key");
     preference.setOnPreferenceChangeListener(new Preference.OnPreferenceChangeListener() {
            @Override
            public boolean onPreferenceChange(Preference preference, Object newValue) {
                Log.d("Preference ", "" + preference);
                Log.d("newValue", "" + newValue);
                return true;
            }
        });

Android: How to get the time from a TimePicker when it is typed in

I hadn't noticed this problem until i stumbled upon this question.
There is a simple solution:
When the user is done changing the date and time in my app, i simply call finish() and in the onPause() or onStop() or onDestroy() I do this:

// force the timepicker to loose focus and the typed value is available !
timePicker.clearFocus();
// re-read the values, in my case i put them in a Time object.
time.hour   = timePicker.getCurrentHour();
time.minute = timePicker.getCurrentMinute();

After this i store the time.toMillis(false) value in the appropriate column of my table.

I don't know if the timepicker is still accessible in your onDialogClosed(boolean positiveResult). If not, find another callback to use when it still is.

Hope this helps.

Layout for TimePicker-based DialogPreference

I've figured it out and fixed it. It now works in every level of the API from Cupcake (1.5 - level 3) to Gingerbread (2.3.3 - level 10). Code is below. Please note that the original code is Apache-licensed as specified in the question. I hereby dedicate all of my modifications to the public domain.
