Custom Control----Countdown control

First on:

Because the time and seconds have their own background color layout, so rewrite a textview is not flexible enough, so we customize a timetextview inherit from LinearLayout and then put a few textview in it.
Let's look at the layout file first:

<?xml version="1.0"encoding="Utf-8"? ><linearlayout xmlns:android="Http://schemas.android.com/apk/res/android"Android:layout_width="Match_parent"android:layout_height="Match_parent"Android:layout_marginbottom="@dimen/default_margin"android:layout_marginleft="@dimen/default_margin"android:layout_marginright="@dimen/default_margin"Android:background="@android: color/transparent"android:gravity="Center"android:orientation="Horizontal"android:padding="@dimen/default_margin_small"> <textview android:id="@+id/tv_hours"Android:layout_width="Wrap_content"android:layout_height="Wrap_content"Android:background="@drawable/background_btn_red"android:padding="@dimen/default_margin_small"android:text=" the"Android:textcolor="@color/white"Android:textsize="@dimen/text_default"/> <textview android:layout_width="Wrap_content"android:layout_height="Wrap_content"android:text=":"Android:textcolor="@color/default_text_red"Android:textsize="@dimen/text_default"/> <textview android:id="@+id/tv_minutes"Android:layout_width="Wrap_content"android:layout_height="Wrap_content"Android:background="@drawable/background_btn_red"android:padding="@dimen/default_margin_small"android:text="XX"Android:textcolor="@color/white"Android:textsize="@dimen/text_default"/> <textview android:layout_width="Wrap_content"android:layout_height="Wrap_content"android:text=":"Android:textcolor="@color/default_text_red"Android:textsize="@dimen/text_default"/> <textview android:id="@+id/tv_seconds"Android:layout_width="Wrap_content"android:layout_height="Wrap_content"Android:background="@drawable/background_btn_red"android:padding="@dimen/default_margin_small"android:text="XX"Android:textcolor="@color/white"Android:textsize="@dimen/text_default"/></linearlayout>

And then it's the custom linearlayout,

/** * Countdown 3 Text * Created by Fangchao on 2015/3/12 */ Public  class timetextview extends linearlayout {    Private LongMday, Mhour, Mmin, Msecond;//day, hour, minute, second    Private BooleanRun =false;//Did you start theTimer timer =NewTimer (); TextView Vhour, Vmin, vseconds; Public Timetextview(Context context) {Super(context);    INIUI (context); } Public Timetextview(context context, AttributeSet attrs) {Super(context, attrs);    INIUI (context); } Public void INIUI(Context context)        {Layoutinflater Minflater = layoutinflater.from (context); View MyView = minflater.inflate (R.layout.view_time_texviews,NULL);        Vhour = (TextView) Myview.findviewbyid (r.id.tv_hours);        Vmin = (TextView) Myview.findviewbyid (r.id.tv_minutes);        Vseconds = (TextView) Myview.findviewbyid (r.id.tv_seconds);    AddView (MyView); } Public Timetextview(context context, AttributeSet attrs,intDEFSTYLEATTR) {Super(Context, attrs, defstyleattr);    INIUI (context); }PrivateHandler Mhandler =NewHandler () {}; Public Boolean Isrun() {returnRun } Public void Setrun(BooleanRun) { This. Run = run; } Public void Start() {if(!isrun ()) {Setrun (true); Timer.schedule (Task, +, +); }    }/** * Assign values to TextView according to the time difference passed in * * @param Duration */     Public void Settimes(LongDuration) {Date Date =NewDate (duration); Date date1 =NewDate (1L);/*mday = duration/60000/60/24;        Mhour = (Duration-mday * 6000 * 60 * 24)/3600000;        Mmin = (Duration-mhour * 6000 * 60-mday * 3600000 * 24)/60000; Msecond = (duration-mmin * 60000-mhour * 3600000-mday * 3600000 *)/60000;*///need to be modified, test withMday = Date.getday ();        Mhour = Date.gethours ();        Mmin = Date.getminutes ();    Msecond = Date.getseconds (); }/** * Countdown calculation * /    Private void Computetime() {msecond--;if(Msecond <0) {mmin--; Msecond = -;if(Mmin <0) {mmin = -; mhour--;if(Mhour <0) {//Countdown EndMhour = -;                mday--; }}}} TimerTask task =NewTimerTask () {@Override         Public void Run() {Mhandler.post (NewRunnable () {//UI thread                @Override                 Public void Run() {run =true; Computetime ();if(Mday <0) {setvisibility (view.gone); Setrun (false); } vhour.settext (Mhour <Ten? ("0"+ Mhour): Mhour +""); Vseconds.settext (Msecond <Ten? ("0"+ Msecond): Msecond +""); Vmin.settext (Mmin <Ten? ("0"+ mmin): Mmin +"");        }            }); }    };}

Just put the timetextview directly in the place where you need it,
For example, you can set a countdown time in adapter ....

@Override public void Onbindheaderview (Recyclerview. ViewholderHolder, int position) {Headerviewholder Headviewholder = (headerviewholder) holder;Long duration=1426244976513L + $* +-Timeutils. Getcurrenttimeinlong();Log. E("long///////", Timeutils. Getcurrenttimeinlong() +"");if (!headviewholder. Timetextview. Isrun()) {Headviewholder. Timetextview. Settimes(duration);Headviewholder. Timetextview. Start();}    }
