I want to create a simple app in eclipse with a button. I want to make it so that after the button is pushed 10 times a message will pop up. The problem is that when I start the app and push the button 10 times , nothing happens. Could you please tell me what I've done wrong?
Here's my activity file:
package com.example.dialog;
import android.os.Bundle;
import android.view.View;
import android.widget.Button;
import android.app.Activity;
import android.app.AlertDialog;
import android.content.DialogInterface;
import android.content.DialogInterface.OnClickListener;
public class Game extends Activity implements android.view.View.OnClickListener{
#Override
protected void onCreate(Bundle savedInstanceState){
super.onCreate(savedInstanceState);
setContentView(R.layout.game);
Button gamebutton = (Button) findViewById(R.id.gamebutton);
}
#Override
public void onClick(View v){
//TODO Auto-generated method stub
int clicked = 0;
clicked++;
if( clicked==10){
AlertDialog.Builder gamebuild = new AlertDialog.Builder(Game.this);
gamebuild.setMessage("Good");
gamebuild.setCancelable(false);
gamebuild.setPositiveButton("Quit", new DialogInterface.OnClickListener() {
#Override
public void onClick(DialogInterface dialog, int which) {
// TODO Auto-generated method stub
Game.this.finish();
}
});
gamebuild.setNegativeButton("One more!", new DialogInterface.OnClickListener() {
#Override
public void onClick(DialogInterface dialog, int which) {
// TODO Auto-generated method stub
dialog.cancel();
}
});
}
}
}
Thanks for response! I've edited the activity file this way:
package com.example.dialog;
import android.os.Bundle;
import android.view.View;
import android.widget.Button;
import android.app.Activity;
import android.app.AlertDialog;
import android.content.DialogInterface;
import android.content.DialogInterface.OnClickListener;
public class Game extends Activity implements android.view.View.OnClickListener{
int clicked = 0;
#Override
protected void onCreate(Bundle savedInstanceState){
super.onCreate(savedInstanceState);
setContentView(R.layout.game);
Button gamebutton = (Button) findViewById(R.id.gamebutton);
}
#Override
public void onClick(View v){
//TODO Auto-generated method stub
clicked++;
if( clicked==10){
AlertDialog.Builder gamebuild = new AlertDialog.Builder(Game.this);
gamebuild.setMessage("Good");
gamebuild.setCancelable(false);
gamebuild.setPositiveButton("Quit", new DialogInterface.OnClickListener() {
#Override
public void onClick(DialogInterface dialog, int which) {
// TODO Auto-generated method stub
Game.this.finish();
}
});
gamebuild.setNegativeButton("One more!", new DialogInterface.OnClickListener() {
#Override
public void onClick(DialogInterface dialog, int which) {
// TODO Auto-generated method stub
dialog.cancel();
}
});
}
}
}
Still it's not working in a proper way. Sorry for dumb questions: I'm new to android.
new edit:

}
You put the counter inside the onClick function, causing it to reset every time. So, move
int clicked = 0;
from inside the onClick to before your onCreate such as:
int clicked = 0;
#Override
protected void onCreate....
This will make it set to 0 once, then stay equal to whatever it's last value was as long as the app is open and not killed.
Problem is that variable clicked is declared inside onClick. So it's always zero. You have to declare it globally, inside class Game.

Sir, we are developing an app to teach small children write alphabets.. Here we show a screen with two images where one image is on the right side it is just to show the image of the alphabet, and the the other one is a light image where the user can draw on image for practise. I want to validate the image drawn by the user whether he has drawn correctly on the base image or not.!
(Note: I exactly dont know what is the use of "Scaling" which i used in it.)Can i please get a solution because i tried a lot but cudnt get an answer

}
};
}
anybody can help about this error
Replace new OnClickListener() in your alert dialogs positive button click with: new DialogInterface.OnClickListener()
Please call InitialUI Method in onActivityCreated instead of onCreate Method.
#Override
public void onActivityCreated(Bundle savedInstanceState) {
super.onActivityCreated(savedInstanceState);
InitialUI();
}
May be it'll helpful to you. Yeah and replace OnClickListerner with DialogInterface.OnClickListener
My Alert dialog message doesn't come out because I cannot get the text of the button. After that the program will directly go to my EventActivity. How can settle this problem?
public void onClick(View v) {
// TODO Auto-generated method stub
if (v.getId() == insertButton.getId()) {
if(colorButton.getText().toString().equals("Color")){
colorAlert.show();
}
}
}
This is variable
AlertDialog colorAlert;
AlertDialog in the OnCreate()
AlertDialog.Builder CA = new AlertDialog.Builder(this);
CA.setTitle("Alert Message!");
CA.setMessage("Please insert the level of important for the event.");
CA.setPositiveButton("OK", new DialogInterface.OnClickListener() {
#Override
public void onClick(DialogInterface dialog, int which) {
// TODO Auto-generated method stub
colorAlert.dismiss();
startActivity(new Intent(this, EventActivity.class));
}
});
colorAlert = CA.create();
When you compare a String in Java, use YOUR_STRING.equals("Color");
Update:
change your while into if , because your are running it once.
The move your
startActivity(new Intent(this, EventActivity.class));
in your alertbox positive button handler.
Comparing Strings in Java.
Ok look like you need more help, here is one solution... i let you deal with the EventActivity ;)

alertBuilder.setMessage("myDialog").setCancelable(false).setPositiveButton("yes", new DialogInterface.OnClickListener(){
public void onClick(DialogInterface dialog, int which) {
dialog.cancel();
Intent intent = new Intent(MainActivity.this, EventActivity.class);
String message = colorButton.getText().toString();
intent.putExtra(EXTRA_MESSAGE, message);
startActivity(intent);
}
}).setNegativeButton("cancel", new DialogInterface.OnClickListener(){
public void onClick(DialogInterface dialog, int which) {
dialog.cancel();
}
});
AlertDialog myAlert = alertBuilder.create();
myAlert.show();
}
}
});
}
Adding to wtsang02 answer, you shouldn't put your alert.show in a while like this one... I see coming the infinite loop ;)

I wrote code in activity.java like this..
I want to use dialog in im1, im2, im3, and each have to get another event.
Then, I have to write 3 dialog?
and how I can set [//TODO Auto...] here that I use is like..
first dialog for im1,
second dialog for im2,
third dialog for im3..
Please help..
You can write a private variable for the alert dialog and reuse it, but not at the same time
private AlertDialog mDialog = new AlertDialog.Builder(this)
.setTitle("Gmelon")
.setMessage("setting?")
.setPositiveButton("YES",
new DialogInterface.OnClickListener() {
#Override
public void onClick(DialogInterface dialog, int which) {
Log.i("MyTag" , "Click YES");
}
})
.setNegativeButton("NO",
new android.content.DialogInterface.OnClickListener() {
#Override
public void onClick(DialogInterface dialog, int which) {
Log.i("MyTag", "Click NO");
}
}).create();
now you can show the dialog where ever you want in your code.
It looks like you could just use showDialog(x) to me unless there is more to this question.
Can someone explain to me why this AlertDialog crashes?

clickerText.setText("0");
final AlertDialog.Builder resetQuestion = null;
resetQuestion.setTitle("Reset?");
resetQuestion.setMessage("Are you sure you want to reset the counter?");
resetQuestion.setPositiveButton("Yes", new OnClickListener() {
public void onClick(DialogInterface dialog, int whichButton) {
clickerNumber = 0;
clickerText.setText("0");
}
});
resetQuestion.setNegativeButton("No", new OnClickListener() {
public void onClick(DialogInterface dialog, int whichButton) {
dialog.dismiss();
}
});
clickerButton.setOnClickListener(new View.OnClickListener() {
public void onClick(View v) {

clickerText.setText(Integer.toString(clickerNumber));
}
});
resetButton.setOnClickListener(new View.OnClickListener() {
public void onClick(View v) {

});
};
};
This is a great fail:
final AlertDialog.Builder resetQuestion = null;
resetQuestion.setTitle("Reset?");
You are trying to use a null object, and that (of course) will throw a NullPointerException
This is how I create dialogs (and I think it's the best way to do it):
LayoutInflater factory = LayoutInflater.from(this);
final View textEntryView = factory.inflate(R.layout.dialogo_layout, null);
final AlertDialog.Builder resetQuestion = new AlertDialog.Builder(YourActivity.this)
// do whatever you want with the resetQuestion AlertDialog
Here, R.layout.dialogo_layout represent a file called dialogo_layout.xml in the res/layout dir that contains the dialog layout.
