I have a if then statement. If the if then statement is true, I want an Android system to fire a basic alert with one button that says ok.
I have done plenty of research, but nothing works.
this is how you create Alert in android
AlertDialog.Builder builder = new AlertDialog.Builder(this);
builder.setMessage("Write your message here.");
builder.setNeutralButton(
"Ok",
new DialogInterface.OnClickListener() {
public void onClick(DialogInterface dialog, int id) {
dialog.cancel();
}
});
builder.create().show()

Trying to build a mobile application and have tested across some devices, but when it comes to Samsung S5 Notebook and J700 mobile phones, both have been failing because they have failed to display the neutral button in the application, please who might have the slightest clue to solving this particular issue. Thanks.
Here is a sample code below;
new AlertDialog.Builder(context)//new Alert Dialog
.setTitle("Delete entry")//set title
.setMessage("Are you sure you want to delete this entry?")
.setNeutralButton(android.R.string.yes, new DialogInterface.OnClickListener() {
public void onClick(DialogInterface dialog, int which) {
// continue with delete
}
})`enter code here`
.setIcon(android.R.drawable.ic_dialog_alert)
.show();
just replace with this -
AlertDialog.Builder builder = new AlertDialog.Builder(context)//new Alert Dialog
.setTitle("Delete entry")//set title
.setMessage("Are you sure you want to delete this entry?")
.setNeutralButton(android.R.string.yes, new DialogInterface.OnClickListener() {
public void onClick(DialogInterface dialog, int which) {
// continue with delete
}
})
.setIcon(android.R.drawable.ic_dialog_alert);
// .show();
AlertDialog d = builder.create();
d.show();
Maybe you should try with .setPositiveButton this should work.
Check if you are using AlertDialog from support library?
ongoing video call got disconnected when it goes to on pause because of do not keep activities checked under developer option in android device how can a user stay in video instead of that option is checked
You can check "Is the do not keep activities is checked or not" by using below line,
int value = Settings.System.getInt(getContentResolver(), Settings.System.ALWAYS_FINISH_ACTIVITIES, 0);
If it returns one, create a AlertDialog and ask the user to disable it first, if user clicks on positive button then create an intent for the Settings like below,
int value = Settings.System.getInt(getContentResolver(), Settings.System.ALWAYS_FINISH_ACTIVITIES, 0);
if (value == 1)
{
AlertDialog.Builder alertDialogBuilder = new AlertDialog.Builder(
context);
// set title
alertDialogBuilder.setTitle("");
// set dialog message
alertDialogBuilder
.setMessage("You need to disable `do not keep activities` option, press YES")
.setCancelable(false)
.setPositiveButton("Yes",new DialogInterface.OnClickListener() {
public void onClick(DialogInterface dialog,int id) {
dialog.dismiss();
startActivity(new Intent(android.provider.Settings.ACTION_APPLICATION_DEVELOPMENT_SETTINGS));
}
})
.setNegativeButton("No",new DialogInterface.OnClickListener() {
public void onClick(DialogInterface dialog,int id) {
dialog.cancel();
}
});
// create alert dialog
AlertDialog alertDialog = alertDialogBuilder.create();
// show it
alertDialog.show();
}
I am entirely not sure if I got you correctly.
But does this: https://developer.android.com/training/scheduling/wakelock.html
answer your question?
It prevents your app from entering onPause, when a voice-chat is ongoing.
Suddenly (without any changes in this project code) I started to obtained an error:
java.lang.RuntimeException: Unable to start activity ComponentInfo{<package>}: java.lang.IllegalArgumentException: Button does not exist
that error points to a method which wasn't yet called.
private void dialog(String title, String content){
AlertDialog alertDialog = new AlertDialog.Builder(MainActivity.this).create();
alertDialog.setTitle(title);
alertDialog.setMessage(content);
alertDialog.setCancelable(true);
alertDialog.setButton(1, "OK", new DialogInterface.OnClickListener() {
public void onClick(DialogInterface dialog, int which) {
dialog.dismiss();
}
});
alertDialog.show();
}
I tried to copy and use that code in other project - same result, and it was working not long ago (same target API etc.). Any idea what I'm overlooking?
Don't hardcode 1 in setButton(...). Use the constants found in the DialogInterface class to specify which button:
DialogInterface.BUTTON_NEGATIVE
DialogInterface.BUTTON_POSITIVE
DialogInterface.BUTTON_NEUTRAL
Change this line:
alertDialog.setButton(1, "OK", new DialogInterface.OnClickListener() {
To one of these:
alertDialog.setButton(DialogInterface.BUTTON_POSITIVE, "OK", new DialogInterface.OnClickListener() {
alertDialog.setButton(DialogInterface.BUTTON_NEGATIVE, "OK", new DialogInterface.OnClickListener() {
alertDialog.setButton(DialogInterface.BUTTON_NEUTRAL, "OK", new DialogInterface.OnClickListener() {
You can look at the Android Documentation on the DialogInterface and on the AlertDialog to look at the setButton methods.
You could also replace BUTTON_POSITIVE, BUTTON_NEGATIVE, and BUTTON_NEUTRAL with their constant values: -1, -2, and -3, respectively.
So for example:
// positive button
alertDialog.setButton(-1, "OK", new DialogInterface.OnClickListener() {
Dialog dialog = new AlertDialog.Builder(Activity01.this)
.setTitle("Login hint")
.setMessage("Here needs your login!")
.setPositiveButton(...)
.setNeutralButton(...
).create();
What kind of grammar it is? I cannot understand why those dots are one by one? And the create() is for Builder() or for setNeutralButton()?
Thanks!
Builder is a static inner class of AlertDialog. Each call returns this allowing you to chain methods. Finally you call create() to create the actual dialog. This is basic Java and has little to do with Android, besides the fact that Android uses this pattern a lot.
setTitle, setMessage are the methods of the DialogBox.
you can also write
Dialog dialog = new AlertDialog.Builder(Activity01.this);
dialog.setTitle("Login hint")
dialog.setMessage("Here needs your login!")
dialog.setPositiveButton(...)
dialog.setNeutralButton(...)
dialog .create();
if you want more clarification about this you can visit this
.setPositiveButton(...) refers you want to pass text to displayed and write the logic for click events.
Refer here:
AlertDialog.Builder builder = new AlertDialog.Builder(this);
builder.setMessage("Are you sure you want to exit?")
.setCancelable(false)
.setPositiveButton("Yes", new DialogInterface.OnClickListener() {
public void onClick(DialogInterface dialog, int id) {
MyActivity.this.finish();
}
})
.setNegativeButton("No", new DialogInterface.OnClickListener() {
public void onClick(DialogInterface dialog, int id) {
dialog.cancel();
}
});
AlertDialog alert = builder.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
