How do i exit runnable and switch another activity

How do i exit runnable and switch another activity - java

I have a textview timer, i want it stops after 10 seconds of showing on display and after 10 seconds that my current activity jumps to an other activity
Runnable runnable = new Runnable()
{
#Override
public void run()
{
while(Running)
{
try{
Thread.sleep(1000);
}catch(InterruptedException e)
{
e.printStackTrace();
}
handler.post(new Runnable()
{
#Override
public void run()
{
number+=1;
tvTimer.setText(String.valueOf(number)); //With setting value of number on textfield ITS POSSIBLE TO SEE THE TIMER
if(number==10)
{
Running = false;
handler.removeCallbacks(this);//that does not works for me to stop
Intent i = new Intent(getApplicationContext(), SonucMenu.class);
startActivity(i); //Starting my second class
}
}
});
}
}
My Second activity starts but the layout from second activity comes more than one time, what i want is that it comes only one time, and i think this problem depends on that i cant stop runnable

I think for this you can use following code , It worked for me.
It will start your activity after 10 seconds.
new Handler().postDelay(new Runnable() {
#Override
public void run() {
Start Your activity here.
}
}, 10000);
but one of the best solution will be (I just found it from develoer site):
new CountDownTimer(10000, 1000) {
public void onTick(long millisUntilFinished) {
mTextField.setText("seconds remaining: " + millisUntilFinished / 1000);
}
public void onFinish() {
strat your activity here.
}
}.start();

Use View.post(Runnable) and View.postDelayed(Runnable, long), no need to create additional thread.
private TextView tvTimer;
private final Runnable mCountDownRunnable = new Runnable() {
private int mCount = 0;
#Override
public void run() {
mCount++;
if (mCount < 10) {
tvTimer.setText(Integer.toString(mCount));
tvTimer.postDelayed(this, 1000);
} else {
Intent i = new Intent(YourActivity.this, SonucMenu.class);
YourActivity.this.startActivity(i);
}
}
};
to start runnable, call tvTimer.post(mCountDownRunnable);

The fact that you have created a constructor for the Something class
public Something(Activity a) {
click();
}
instead of using onCreate() is probably the source of the error.
Something is derived from Activity, in which you have to override onCreate() at the very least, and set the View of your Activity in it. You haven't done that, and instead you have created a constructor for Something which is also not allowed.
The solution to your problem is to replace the constructor with onCreate() and set the View of that Activity using setContentView(). Also, you cannot create an Activity object using
new Something(this);

You need to handle onClick of the button in this manner and show a toast if the edittext is empty
if(editText.getText().toString().trim().length()==0){
Toast.makeText(getApplicationContext(), "field is empty",
Toast.LENGTH_LONG).show();
}else{
//your code here
}

If you want to check for empty EditText.. try TextUtils for it.
Example
if (TextUtils.isEmpty(edtText.getText().toString().trim())) {
Toast.makeText(getBaseContext(),
"Empty", Toast.LENGTH_SHORT)
.show();
} else {
Toast.makeText(getBaseContext(),
"Not Empty", Toast.LENGTH_SHORT)
.show();
}

How would i make a button to switch where points go in a counter?

I am currently a high school student who decided to try and take up Android dev for fun, but I am stumped. I have an image button for blue team and for red team. The score goes up automatically for blue team. What i dont know how to do is when you hit the red button, the image buttons make the red teams score go up and vice versa.
Here is my java code
package com.example.puremmacompetitionjiujitsuscorer;
import android.app.Activity;
import android.os.Bundle;
import android.view.Menu;
import android.view.View;
import android.widget.ImageButton;
import android.widget.TextView;
import android.widget.Toast;
class MainActivity extends Activity {
private int blueScore = 0;
private int redScore = 0;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
final ImageButton sweep = (ImageButton) findViewById(R.id.imageButton5);
final ImageButton pass = (ImageButton) findViewById(R.id.imageButton8);
final ImageButton mount = (ImageButton) findViewById(R.id.imageButton4);
final ImageButton backMount = (ImageButton) findViewById(R.id.imageButton3);
final ImageButton kneeOnBelly = (ImageButton) findViewById(R.id.imageButton7);
final ImageButton takeDown = (ImageButton) findViewById(R.id.imageButton6);
final TextView blueScoreCount = (TextView) findViewById(R.id.blueScore1);
takeDown.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
// TODO Auto-generated method stub
blueScore += 2;
blueScoreCount.setText("" + blueScore);
}
});
sweep.setOnClickListener(new View.OnClickListener(){
public void onClick(View w) {
blueScore += 2;
blueScoreCount.setText("" + blueScore);
}
});
pass.setOnClickListener(new View.OnClickListener(){
public void onClick(View q){
blueScore += 3;
blueScoreCount.setText("" + blueScore);
}
});
mount.setOnClickListener(new View.OnClickListener(){
public void onClick(View t){
blueScore += 4;
blueScoreCount.setText("" + blueScore);
}
});
backMount.setOnClickListener(new View.OnClickListener(){
public void onClick(View s){
blueScore += 4;
blueScoreCount.setText("" + blueScore);
}
});
kneeOnBelly.setOnClickListener(new View.OnClickListener(){
public void onClick(View g){
blueScore += 2;
blueScoreCount.setText("" + blueScore);
}
});
};
#Override
public boolean onCreateOptionsMenu(Menu menu) {
// Inflate the menu; this adds items to the action bar if it is present.
getMenuInflater().inflate(R.menu.main, menu);
return true;
}

I think I possibly understand you. If I do, you can use a flag to see which Button was pressed. So the flow would be like
Red button pressed -> flag = red -> Score Button pressed -> red score += score
In code it would be like
String flag = "";
public void onRedBtnClick(View v)
{
flag = "red";
}
public void scoreBtnClick(View v)
{
if (!flag.equals(""));
{
if ("red".equals(flag))
{
redScore += score;
}
if ("blue".equals(flag))
{
blueScore += score;
}
}
This is obviously done really quick and you will have to adjust your variables to your needs. But if I understand what you want then this would give you the basic logic
