I am using AlertDialog to show any message and links, I use this code. But I want to show a different message (link) in every action randomly. Is that possible? and if it is, can you give me sample codes for this. thanks.
final AlertDialog d = new AlertDialog.Builder(this)
.setPositiveButton(android.R.string.ok, null)
.setIcon(R.drawable.icon)
.setMessage(Html.fromHtml("Check this link out"))
.create();
d.show();
// Make the textview clickable. Must be called after show()
((TextView)d.findViewById(android.R.id.message)).setMovementMethod(LinkMovementMethod.getInstance());
what i want is: when user opens my application, my alertbox shows a link but i want to use many links and show them randomly, I will use it for like text ads. I mean when user open my app google.com will be shown and another time yahoo.com and another time a different link. Hope i am clear
You can use this:
public static void showAlertDialog(final String title, String message,
final Context context, final boolean redirectToPreviousScreen) {
AlertDialog.Builder alertbox = new AlertDialog.Builder(context);
alertbox.setMessage(message);
alertbox.setTitle(title);
alertbox.setNeutralButton("Ok", new DialogInterface.OnClickListener() {
public void onClick(DialogInterface arg0, int arg1) {
}
});
try{
alertbox.show();
}catch (Exception b) {
}
}

I am asking the same question which is asked before at below links but the solution proposed in these links is not working for me so I am posting it again.
How to make an AlertDialog disappear?
Android AlertDialog always exits when I click on OK Button
How to navigate to next activity after user clicks on AlertDialog OK button?
Basically, I am creating an AlertDialog builder to notify the user for asking to enable a setting for the Usage Data Access and when the OK button is pressed then the Settings menu gets opened. When I press back button to come back on the app then the AlertDialog is still available there although I expected to be dismissed to be back on my app.
public void show_alert(){
AlertDialog.Builder builder = new AlertDialog.Builder(this);
builder.setMessage("This application requires access to the Usage Stats Service. Please " +
"ensure that this is enabled in settings, then press the back button to continue ");
builder.setCancelable(true);
builder.setPositiveButton(
"OK",
new DialogInterface.OnClickListener() {
#Override
public void onClick(DialogInterface dialog, int id) {
Intent intent = new Intent(Settings.ACTION_USAGE_ACCESS_SETTINGS);
startActivity(intent);
dialog.dismiss();
}
});
builder.show();
return;
}
Any hint what wrong could be going here?
Edit after some testing:
I tested OPs code on 6.0.1 and it behaved as expected - i.e. the dialog was dismissed after clicked 'OK'. I'll leave my initial answer below as an alternative that also works. Additional alternatives can be found here.
You can get a reference to your Alert Dialog it from your builder.show() method:
mMyDialog = builder.show();
In your onClick method:
mMyDialog.dismiss();
Full sample:
AlertDialog mMyDialog; // declare AlertDialog
public void show_alert(){
AlertDialog.Builder builder = new AlertDialog.Builder(this);
builder.setMessage("This application requires access to the Usage Stats Service. Please " +
"ensure that this is enabled in settings, then press the back button to continue ");
builder.setCancelable(true);
builder.setPositiveButton(
"OK",
new DialogInterface.OnClickListener() {
#Override
public void onClick(DialogInterface dialog, int id) {
Intent intent = new Intent(Settings.ACTION_USAGE_ACCESS_SETTINGS);
startActivity(intent);
mMyDialog.dismiss(); // dismiss AlertDialog
}
});
mMyDialog = builder.show(); // assign AlertDialog
return;
}
I couldn't find anything usefull on the internet about my problem. So my question is how do you do a good usage of Android's alert dialogs. Here is an example of code creating and showing an alert dialog just with the title "error", the text "you can't do that" and a "Ok" button :
AlertDialog.Builder alertDialogBuilder = new AlertDialog.Builder(this);
alertDialogBuilder.setTitle("Error");
alertDialogBuilder.setMessage("You can't do that");
alertDialogBuilder.setCancelable(true);
alertDialogBuilder.setPositiveButton(
getResources().getString("ok"),
new DialogInterface.OnClickListener() {
public void onClick(DialogInterface dialog, int id) {
dialog.cancel();
}
});
alertDialogError = alertDialogBuilder.create();
alertDialogError.show();
But now, if I have many of this alert dialogs in my application, what should I do ?
Should I set the alertDialogBuilder as an attribute so each time I want to display an error message I can call his function setMessage() and then create() and then show() ?
Should I keep an already configured alertDialog for every single error message I have so I can just call theRightAlertDialog.show() to display my message ?
Something else ?
What's the good usage/cleanest way to do this for you ?
You could do this one of two ways. The first is to create a static method, which you can place in a final utility class:
public final class AlertUtil {
public static void showErrorDialog(Context context, String message) {
AlertDialog.Builder builder = new AlertDialog.Builder(context);
builder.setTitle("Error");
builder.setMessage(message);
builder.setCancelable(true);
builder.setPositiveButton(
getResources().getString("ok"),
new DialogInterface.OnClickListener() {
#Override
public void onClick(DialogInterface dialog, int id) {
dialog.cancel();
}
});
builder.show();
}
}
Or you can use a DialogFragment which you can create with:
getSupportFragmentManager().beginTransaction().add(ErrorDialogFragment.newInstance(message), "tag").commit()`
I will say though, as a side note; if you are looking to change more than just a few fields for each of the dialogs (i.e. adding more parameters to the showErrorDialog method), then you probably should just stick to the Builder pattern. Considering that is what the Builder pattern is meant for.
Should I set the alertDialogBuilder as an attribute so each time I want to display an error message I can call his function setMessage() and then create() and then show() ?
If the title and the button functionality are the same for all of your alerts, than this would be the best strategy. Create a variable for the alertDialogBuilder, or even just the alertDialog itself, then change the message and show it each time.
Alternatively, you could create a method that builds the dialog, and takes in a string for the message text.
I need help to pass values from a custom dialog to an activity.
I cannot understand what should i use. I already used intent, but dialog doesn't support intent value passing .
So anyone can help me here, i am totally stucked.If you have any basic example for it, then that will be excellent.
Thank You.
Snippet from the Google Documentation:
// Alert Dialog code (mostly copied from the Android docs
AlertDialog.Builder builder = new AlertDialog.Builder(this);
builder.setTitle("Pick a color");
builder.setItems(items, new DialogInterface.OnClickListener() {
public void onClick(DialogInterface dialog, int item) {
myFunction(item);
}
});
AlertDialog alert = builder.create();
// Now elsewhere in your Activity class, you would have this function
private void myFunction(int result){
// Now the data has been "returned" (as pointed out, that's not
// the right terminology)
}
I have to get a password from user via AlertDialog and EditText. When user opens this AlertDialog and then presses Cancel or back button, it disappears normally. However when user opens this AlertDialog again, application will be broken. My code here, where am I making mistake?
sifrePencere.setTitle("Çıkış");
sifrePencere.setMessage("Uygulamayı kapatmak için lütfen şifreyi giriniz:");
sifrePencere.setView(sifre);
sifrePencere.setPositiveButton("Tamam", new DialogInterface.OnClickListener() {
#Override
public void onClick(DialogInterface dialog, int which) {
String girilenSifre = sifre.getText().toString();
SQLiteDatabase db = vt.getReadableDatabase();
Cursor kayit = db.rawQuery("SELECT sifre FROM CocukTableti", null);
kayit.moveToFirst();
if (girilenSifre.equals(kayit.getString(0))) {
android.os.Process.killProcess(android.os.Process.myPid());
} else {
dialog.dismiss();
dialog.cancel();
Toast.makeText(getApplicationContext(), "Girilen şifre hatalı!", Toast.LENGTH_SHORT).show();
}
}
});
sifrePencere.setNegativeButton("Vazgeç", null);
sifrePencere.show();
I was showing this AlertDialog in OptionsMenu. But I defined the variables on top of my codes. So, error comes from here. I defined these variables into OnOptionsItemClick, it fixed!
On top of your code write
mybuilder = new AlertDialog.Builder(this);
and before
sifrePencere.show():
write this statement
myAlertDialog = mybuilder.create();
I am working on an android project where I am trying to show a AlertDialog in a separate normal java class and return the result that the user enters. I can display the dialog fine but the problem I am having is it always returns the value before the dialog has had one of the buttons pressed.
Below is the code that calls the function in the standard java class to show the dialog
private void showDiagreeError()
{
Common common = new Common(this);
boolean dialogResult = common.showYesNoDialog();
Toast.makeText(getApplicationContext(), "Result: " + dialogResult, Toast.LENGTH_LONG).show();
}
And below is the code that shows the actual dialogue
public boolean showYesNoDialog()
{
AlertDialog.Builder builder = new AlertDialog.Builder(context);
builder.setMessage("Are you sure you do not want to agree to the terms, if you choose not to, you cannot use Boardies Password Manager")
.setCancelable(false)
.setPositiveButton("Yes", new DialogInterface.OnClickListener() {
public void onClick(DialogInterface dialog, int which) {
dialogResult = true;
}
})
.setNegativeButton("No", new DialogInterface.OnClickListener() {
public void onClick(DialogInterface dialog, int which) {
dialogResult = false;
}
});
AlertDialog alert = builder.create();
alert.show();
return dialogResult;
}
dialogResult is a global variable visible throughout the class and being set to false. As soon as the dialog is shown the toast message is shown showing the result is false, but I was expecting the return statement to block until the user has pressed one of the buttons too set the variable to the correct value.
How can I get this to work.
After many hours hunting through the inner depths of google pages, I found this Dialogs / AlertDialogs: How to "block execution" while dialog is up (.NET-style).
It does exactly the job I was after and tested to make sure there are no ANR errors, which there isn't
