I need help in here, so i want to use Handler to auto Random my case list every 2 second
the full code is like this
public class play extends Activity implements View.OnClickListener{
int number;
Button button1, button2, button3, button4, button5, button6, button7, button8, button9, button10, button11, button12, button13, button14, button15, button16;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
this.requestWindowFeature(Window.FEATURE_NO_TITLE);
getWindow().setFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN,
WindowManager.LayoutParams.FLAG_FULLSCREEN);
setContentView(R.layout.play);
button1 = (Button)findViewById(R.id.button1);
button2 = (Button)findViewById(R.id.button2);
button3 = (Button)findViewById(R.id.button3);
button4 = (Button)findViewById(R.id.button4);
button5 = (Button)findViewById(R.id.button5);
button6 = (Button)findViewById(R.id.button6);
button7 = (Button)findViewById(R.id.button7);
button8 = (Button)findViewById(R.id.button8);
button9 = (Button)findViewById(R.id.button9);
button10 = (Button)findViewById(R.id.button10);
button11 = (Button)findViewById(R.id.button11);
button12 = (Button)findViewById(R.id.button12);
button13 = (Button)findViewById(R.id.button13);
button14 = (Button)findViewById(R.id.button14);
button15 = (Button)findViewById(R.id.button15);
button16 = (Button)findViewById(R.id.button16);
//i had use setOnClickListener(This) to make all of button do same logic in one method
// correct me if i wrong
button1.setOnClickListener(this);
button2.setOnClickListener(this);
button3.setOnClickListener(this);
button4.setOnClickListener(this);
button5.setOnClickListener(this);
button6.setOnClickListener(this);
button7.setOnClickListener(this);
button8.setOnClickListener(this);
button9.setOnClickListener(this);
button10.setOnClickListener(this);
button11.setOnClickListener(this);
button12.setOnClickListener(this);
button13.setOnClickListener(this);
button14.setOnClickListener(this);
button15.setOnClickListener(this);
button16.setOnClickListener(this);
}
// this is the method to make all of the button do same logic with one method
// correct me if i wrong
@Override
public void onClick(View v) {
//i use the handler method to do auto-random every 2 second
// correct me if i wrong
final Handler mHandler = new Handler();
final int ms=2000; //2secs.
//i got error in this line
// Define cannot be resolved to a type, Syntax error on token ":", { expected after this token, Syntax error, insert ";" to complete
Define a Runnable:
final Runnable mUpdateTimeTask = new Runnable() {
public void run() {
Random generator = new Random();
number = generator.nextInt(16) + 1;
// The '16' is the number of values
// Here, we are checking to see what the output of the random was
switch(number) {

}
// the auto-random will be faster and faster
// correct me if i do it wrong too
ms=ms-20; //20ms faster
mHandler.postDelayed(this, ms);
}
};
mHandler.postDelayed(mUpdateTimeTask, 100);
}
}
i'm sorry if you're madness look at my code, because that i was need help with people more experience to fix or give another sample code as solution for the current mistake on my code
Thanks in Advance.
