I am trying to display a multiplication table with delay. My code is working fine but I am not able to implement the delay.
Here is My code:
tableButton1 = (Button) findViewById(R.id.Button1);
tableButton1.setOnClickListener(new OnClickListener() {
public void onClick(View v) {
new Thread(new Runnable() {
public void run() {
str = tableButton1.getText().toString();
a = Integer.parseInt(str);
StringBuilder sb = new StringBuilder();
for (int i = 1; i <= 10; i++){
sb.append(a + " x " + i + " = " + i * a+ "\n");
}
s = String.valueOf(sb);
Intent intent=new Intent(getApplicationContext(),TextViewActivity.class);
intent.putExtra("MA", s);
startActivity(intent);
}
});
//Toast.makeText(getApplicationContext(), "Hi" +ss, 222).show();
}
});
Any answer is appreciable.
Thank's in advance
Updated-code:- This code is working with help of @theLittleNaruto
import android.app.Activity;

public class TestActivity extends Activity{

int value = 0;
static int count = 0;
Handler handle = new Handler();
StringBuilder sb = new StringBuilder();
Runnable r = new Runnable() {
@Override
public void run() {
Toast.makeText(getApplicationContext(), "onrunnable" +sb, 222).show();
// TODO Auto-generated method stub
updateTable();
}
};
@Override

super.onCreate(savedInstanceState);
setContentView(R.layout.text_display);
Toast.makeText(getApplicationContext(), "oncreate" , 222).show();
txtView = (TextView) findViewById(R.id.outputTXT);
tableButton1 = (Button) findViewById(R.id.seven);
tableButton1.setOnClickListener(new OnClickListener() {

updateTable();
}
});
}
public void updateTable(){
count+=1000;
if(count==11000){
//Toast.makeText(getApplicationContext(), "onupdate" , 222).show();
count = 0;
value=0;
handle.removeCallbacks(r);
sb.setLength(0);
}else{
sb.append(value + " x " + count/1000 + " = " + count/1000 * value+ "\n");
handle.postDelayed(r, 1000);
// Toast.makeText(getApplicationContext(), "onupdateElse" +sb, 222).show();
txtView.setText(sb);
}
}
}
Thank you all the supporters and their best try to help me
Why dont you try what the other is saying with this little effort ;)
public class TestActivity extends Activity{
int value = 0;
static int count = 0;
Handler handle = new Handler();
StringBuilder sb = new StringBuilder();
Runnable r = new Runnable() {
@Override
public void run() {
// TODO Auto-generated method stub
updateTable();
}
};
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.oaot_get);
tableButton1.setOnClickListener(new View.OnClickListener() {
public void onClick(View v) {
value= Integer.parseInt(tableButton1.getText().toString());
updateTable();
}
});
}
public void updateTable(){
count+=1000;
if(count==11000){
count = 0;
value=0;
handle.removeCallbacks(r);
sb.setLength(0);
}else{
sb.append(value + " x " + count/1000 + " = " + count/1000 * value+ "\n");
handle.postDelayed(r, 1000);
}
}
}

Try this
Timer timer = new Timer();
timer.schedule(new TimerTask() {
public void run() {
str = tableButton1.getText().toString();
a = Integer.parseInt(str);
StringBuilder sb = new StringBuilder();
for (int i = 1; i <= 10; i++){
sb.append(a + " x " + i + " = " + i * a+ "\n");
}
}, 5000);
s = String.valueOf(sb);
Intent intent=new Intent(getApplicationContext(),TextViewActivity.class);
intent.putExtra("MA", s);
startActivity(intent);
Add a handler(). Replace your onClick code with:
final Handler handler = new Handler();
handler.postDelayed(new Runnable() {
@Override
public void run() {
str = tableButton1.getText().toString();
a = Integer.parseInt(str);
StringBuilder sb = new StringBuilder();
for (int i = 1; i <= 10; i++)
{
sb.append(a + " x " + i + " = " + i * a+ "\n");
}s=String.valueOf(sb);
Intent intent=new Intent(getApplicationContext(),TextViewActivity.class);
intent.putExtra("MA", s);
startActivity(intent);
}
}, 5000);
Repalce 5000 with the time you want it to be delayed for in milliseconds
Add a Handler that will execute your runnable:
Runnable runnable = new Runnable() {
@Override
public void run() {
str = tableButton1.getText().toString();
a = Integer.parseInt(str);
StringBuilder sb = new StringBuilder();
for (int i = 1; i <= 10; i++){
sb.append(a + " x " + i + " = " + i * a+ "\n");
//--ADDED stuff here------------------------------------------------------------
try {
//Sleep will suspend your Thread for 500 miliseconds and resumes afterwards
Thread.sleep(500);
} catch (InterruptedException e) {
Log.e("error, Thread interrupted", e);
}
}
s = String.valueOf(sb);
Intent intent=new Intent(getApplicationContext(),TextViewActivity.class);
intent.putExtra("MA", s);
startActivity(intent);
}
Handler handler = new Handler();
//this will execute your runnable after 500 milliseconds
handler.postDelayed(runnable, 500);
You can use that :
public class Scheduler {
// DATA
private OnScheduleTimeListener mListener;
private Handler mHandler;
private int mInterval; // Between each executions
private static final int DELAY = 100; // before first execution
private boolean mIsTimerRunning;
public static interface OnScheduleTimeListener {
public void onScheduleTime();
}
public Scheduler(int interval) {
super();
mInterval = interval;
mHandler = new Handler();
}
private final Runnable mRunnable = new Runnable() {
@Override
public void run() {
// Do stuff
mListener.onScheduleTime();
// Repeat
mHandler.postDelayed(mRunnable, mInterval);
}
};
public void setOnScheduleTimeListener(OnScheduleTimeListener listener) {
mListener = listener;
}
public void startTimer() {
mIsTimerRunning = true;
mHandler.postDelayed(mRunnable, DELAY);
}
public void stopTimer() {
mIsTimerRunning = false;
mHandler.removeCallbacks(mRunnable);
}
public boolean isTimerRunning() {
return mIsTimerRunning;
}
}
Now to use it :
private void startTimer() {
mScheduler = new Scheduler(INTERVAL);
mScheduler.setOnScheduleTimeListener(new OnScheduleTimeListener() {
@Override
public void onScheduleTime() {
Log.d(TAG, "update");
});
mScheduler.startTimer();
}
private void stopTimer(){
if (mScheduler != null && mScheduler.isTimerRunning()) {
mScheduler.stopTimer();
mScheduler = null;
}
}

Try this....
do {
try {
try {
response_req_sequence = SimpleHttpClient
.sendresponseSequReqRes(response_send_order);
System.out.println("response of sequence request"
+ response_req_sequence);
System.out.println(" i ma in thread");
if (response_req_sequence.trim().length() != 0) {
System.out.println("response in result of sequ"+ response_req_sequence);
break;
}
Thread.sleep(10000);
} catch (Exception e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
} catch (Exception e) {
// TODO: handle exception
}
} while (response_req_sequence.trim().equalsIgnoreCase(""));
This is working fine for me. you can customize according to you.
