android - How to make text view display temperature data from another method? -


here entire code app. don't beleive have play method: 

package com.solomonreedstudios.thermometer;  import android.content.context; import android.hardware.sensor; import android.hardware.sensorevent; import android.hardware.sensoreventlistener; import android.hardware.sensormanager; import android.media.audiomanager; import android.media.soundpool; import android.os.bundle; import android.os.countdowntimer; import android.support.v7.app.actionbaractivity; import android.view.view; import android.widget.textview;   public class main extends actionbaractivity implements  sensoreventlistener { private sensormanager msensormanager; private sensor mtemperature;  public textview tv1; public textview tv2;  public textview tv3;   soundpool beepint; int beep;   @override public final void oncreate(bundle savedinstancestate) {     super.oncreate(savedinstancestate);     setcontentview(r.layout.activity_sensor_actvity);     tv3 = (textview) findviewbyid(r.id.mtextfield);      beepint = new soundpool(10, audiomanager.stream_music, 0);     beep = beepint.load(this, r.raw.beep, 1);      // instance of sensor service, , use instance of     // particular sensor.     msensormanager = (sensormanager) getsystemservice(context.sensor_service);     mtemperature = msensormanager.getdefaultsensor(sensor.type_ambient_temperature); }  @override public final void onaccuracychanged(sensor sensor, int accuracy) {     // here if sensor accuracy changes. }  @override public final void onsensorchanged(sensorevent event) {     // sensor data.     float lux = event.values[0];     float fahrenheit = lux * 9 / 5 + 32;     tv1 = (textview) findviewbyid(r.id.text1);     tv1.settext(string.valueof(lux));     tv2 = (textview) findviewbyid(r.id.textview2);     tv2.settext(string.valueof(fahrenheit)); } @override protected void onresume() {     //  register  listener sensor.     super.onresume();     msensormanager.registerlistener(this, mtemperature, sensormanager.sensor_delay_normal); }  @override protected void onpause() {     // sure unregister sensor when activity pauses.     super.onpause();     msensormanager.unregisterlistener(this); }    public final void collectdata(view view) {       new countdowntimer(300, 1000) {          public void ontick(long millisuntilfinished) {             tv3.settext("seconds remaining until reading: " + millisuntilfinished / 1000);         }          public void onfinish() {             beepint.play(beep, 1, 1, 1, 0, 1);             tv3.settext("your temperature  " + mtemperature);          }     }.start();  }       }

could help?

c++ - Difference between pre and post decrement in recursive function argument -

i have following sample code used pre-decrement void function(int c) { if(c == 0) { return; } else { cout << "dp" << c << endl; function(--c); cout << c << endl; return; } } this function give output input 4 : dp3 dp2 dp1 dp0 0 1 2 3 but when use post decrement void function(int c) { if(c == 0) { return; } else { cout << "dp" << c << endl; function(c--); cout << c << endl; return; } } output goes in infinite loop dp4 can explain me in detail why happens ? this happens because function(c--) called same value of c , when finishes c decremented. recursively called, hence called same value no chance of return , hit stack overflow error. assume this, int x = 1, y = 0; y = x++ result y == 1 , x == 2. if y = ++x , bot x , y 2.
