အထက္ပါ code ေတြ ေရးၿပီးရင္ေတာ့ project ကုိ Run လိုက္ပါ Error မရွိပဲ အဆင္ေျပရင္ Button ကုိ ႏိုပ္လိုက္ရင္ Toast message ေလးေတြျပေအာင္ ေအာက္ပါ java code ေလး ေတြ ဆက္ေရးၾကေအာင္ ဗ်ာ ....

java လဲကူးထည့္လို႔ error မရွိေတာ့ရင္ Run လိုက္ပါ ၿပီးရင္ button ေလးေတြ ႏိုပ္ၾကည့္ပါ သက္ဆိုင္ရာ Toast message ေလးေတြျပပါလိမ့္မယ္

အဆင္ေျပပါေစ

Happy Coding
