Closed 5 years ago.
Can someone tell me how exit all activity on android studio, because when show alert dialog exit i click exit when progressbar on proses the app close but few second app auto start and show second activity.

I think you want to exit app when user pressing yes on alert box.. so for this you need to write below code on "yes" button click like this.
Source: this answer
#Override
public void onBackPressed() {
AlertDialog.Builder alertDialogBuilder = new AlertDialog.Builder(this);
alertDialogBuilder.setTitle("Exit Application?");
alertDialogBuilder
.setMessage("Click yes to exit!")
.setCancelable(false)
.setPositiveButton("Yes",
new DialogInterface.OnClickListener() {
public void onClick(DialogInterface dialog, int id) {
moveTaskToBack(true);
android.os.Process.killProcess(android.os.Process.myPid());
System.exit(1);
}
})
.setNegativeButton("No", new DialogInterface.OnClickListener() {
public void onClick(DialogInterface dialog, int id) {
dialog.cancel();
}
});
AlertDialog alertDialog = alertDialogBuilder.create();
alertDialog.show();
}

How do I detect when user closes ussd dialog in Android?

I'm running ussd code from my code. After it returns the results the user will press the ok button to close the the dialog. I want to detect when the user does this.

Let's assume that this is your dialog code:
AlertDialog.Builder builder = new AlertDialog.Builder(this, R.style.AppCompatAlertDialogStyle);
builder.setTitle("dialog's title");
builder.setMessage("dialogs's text");
builder.setPositiveButton("ok", new DialogInterface.OnClickListener() {
public void onClick(DialogInterface dialog, int which) {
//do stuff when user presses ok button
}
});
builder.setNeutralButton("CANCEL", null); //same here just add the listener
AlertDialog dialog = builder.create();
dialog.show();
//you can use neutralButton as well

Change the background of the AlertDialog

i want to know how to change the design of my AlertDialog, the buttons the background.
thank you.
new AlertDialog.Builder(this)
.setTitle("Exit")
.setMessage("Do you want to exit")
.setPositiveButton("Yes", new DialogInterface.OnClickListener() {
public void onClick(DialogInterface dialog, int which) {
finish();
}
})
.setNegativeButton("No", new DialogInterface.OnClickListener() {
public void onClick(DialogInterface dialog, int which) {
// do nothing
}
})
.setIcon(android.R.drawable.ic_menu_zoom)
.show();
}

AlertDialog.Builder alertDialog_ImageSelector=new AlertDialog.Builder(mcontext);
View imageGuideLineInfo=getActivity().getLayoutInflater().inflate(R.layout.your_alyout,null);
alertDialog_ImageSelector.setView(imageGuideLineInfo);
TextView tv_guidelines=(TextView)imageGuideLineInfo.findViewById(R.id.tv_guidelines);
final AlertDialog adinfo=alertDialog_ImageSelector.create();
adinfo.getWindow().setBackgroundDrawable(new ColorDrawable(Color.TRANSPARENT));//here you can change the background of alertDialog.
adinfo.show();
if you want to change the background of buttons then you need to create the buttons in your_view.xml and bind them here and setBackground.

use this android inbuilt theme
AlertDialog.Builder builder = new AlertDialog.Builder(this, AlertDialog.THEME_DEVICE_DEFAULT_LIGHT);

Alert dialog not working correctly - android

I am using an alert dialog to ask the user for confirmation of an item addition to an array. I am printing the array size before and after the alert dialog and it seems that both printings are done before the alert dialog shows up.
Log.d("before", ""+wayPoints.length);
AlertDialog.Builder ab = new AlertDialog.Builder(getContext());
ab .setTitle("Add entry");
ab .setMessage("Are you sure you want to add this entry?");
ab .setPositiveButton(android.R.string.yes, new DialogInterface.OnClickListener()
{
public void onClick(DialogInterface dialog, int which)
{wayPoints = ArrayHandler.addAtIndex(wayPoints, node, 1);}
});
ab .setNegativeButton(android.R.string.no, new DialogInterface.OnClickListener() {
public void onClick(DialogInterface dialog, int which) {
// do nothing
}
});
ab.setIcon(android.R.drawable.ic_dialog_alert);
ab.show();
Log.d("after", ""+wayPoints.length);
The ArrayHandler.addAtIndex method handles the addition of a new item to the provided array.
The problem is it is printing both logging lines before the alert dialog shows up. I need the alert dialog to be done before the printing of the second log.

This is correct behavior. The show method does not wait or block until the dialog is dismissed. Code execution continues after the show method immediately after the dialog is shown. (Actually, the dialog isn't even displayed yet - that happens after you yield control).
You already have setPositiveButton and setNegativeButton handlers, just put the code you want to execute in those handlers when user presses a button.
If you want certain code to run when the dialog is closed regardless of which button is tapped, use setOnDismissListener and put your code there.

Use:
AlertDialog alert1 = ab.create();
alert.show();
Instead of:
ab.show();

Try this
AlertDialog.Builder alertDialogBuilder = new AlertDialog.Builder( context);  
// set title
alertDialogBuilder.setTitle("Your Title");
  // set dialog message
alertDialogBuilder .setMessage("Click yes to exit!") .setCancelable(false) .setPositiveButton("Yes",new DialogInterface.OnClickListener() {
public void onClick(DialogInterface dialog,int id) {
// if this button is clicked, close
// current activity
MainActivity.this.finish(); }
}) .setNegativeButton("No",new DialogInterface.OnClickListener() {
public void onClick(DialogInterface dialog,int id) {
// if this button is clicked, just close
// the dialog box and do nothing
dialog.cancel();
}
.setPositiveButton(android.R.string.yes, new DialogInterface.OnClickListener() {
public void onClick(DialogInterface dialog, int which) {
wayPoints = ArrayHandler.addAtIndex(wayPoints, node, 1);
Log.d("after", ""+wayPoints.length);
} });
});  
// create alert dialog
AlertDialog alertDialog = alertDialogBuilder.create();  
// show it
alertDialog.show();

how do you add an item in a list if a user presses yes button in an alert dialog box and don't add it if he presses no

I am making an app in which if a user selects a
submenu item I pop up an Alert dialog which asks his confirmation
whether he wishes to save that item in his list and saves it if he
presses yes and doesn't add it if he presses no.

You can use this to show alert:
AlertDialog.Builder builder = new AlertDialog.Builder(this);
builder.setMessage("Are you sure to do this?").setCancelable(false).setPositiveButton("Yes", new DialogInterface.OnClickListener() {
public void onClick(DialogInterface dialog, int id) {
doSomeThing();
dialog.cancel();
}
}).setNegativeButton("No", new DialogInterface.OnClickListener() {
public void onClick(DialogInterface dialog, int id) {
dialog.cancel();
}
});
AlertDialog alert = builder.create();
alert.show();

You add the element you get from the dialog to the ArrayList you use to feed your Adapter then feed the cursor = new yourAdapter(YourClass.this.getBaseContext(), android.R.layout.simple_list_item_1, dataList);
Call cursor.notifyDataSetChanged(); which tells the list to repopulate with the new data;
