Get value from dialog
I want to show Dialog
with EditText
. I assume it has two buttons: a positive button, which will save the text contained in EditText
, and a negative button, which will undo and revert to Activity
, which triggered it as if nothing had happened. I tried using AlertDialog
without success:
AlertDialog.Builder builder = new Builder(context);
final EditText text = new EditText(context);
builder.setTitle("New Profile").setMessage("Name this new profile").setView(text);
builder.setPositiveButton("Create", new OnClickListener() {
public void onClick(DialogInterface di, int i) {
final String name = text.getText().toString();
//do something with it
}
});
builder.setNegativeButton("Cancel", new OnClickListener() {
public void onClick(DialogInterface di, int i) {
}
});
builder.create().show();
Am I doing something wrong with the method setView()
? Will using a custom one be Dialog
more practical?
EDIT:
I have several answers that say the code works for them ... not sure why it doesn't work for me. Here's the logcat:

gobernador Agarwal is right, I also tried the code for you and it worked, try replacing the context with this
AlertDialog.Builder builder = new Builder(this);
final EditText text = new EditText(this);
builder.setTitle("New Profile").setMessage("Name this new profile").setView(text);
builder.setPositiveButton("Create", new OnClickListener() {
public void onClick(DialogInterface di, int i) {
final String name = text.getText().toString();
//do something with it
}
});
builder.setNegativeButton("Cancel", new OnClickListener() {
public void onClick(DialogInterface di, int i) {
}
});
builder.create().show();

Try it, it worked for me
AlertDialog.Builder alert = new AlertDialog.Builder(this);
alert.setTitle("Title");
alert.setMessage("Message");
// Set an EditText view to get user input
final EditText input = new EditText(this);
alert.setView(input);
alert.setPositiveButton("Ok", new DialogInterface.OnClickListener() {
public void onClick(DialogInterface dialog, int whichButton) {
String value = input.getText();
// Do something with value!
}
});
alert.setNegativeButton("Cancel", new DialogInterface.OnClickListener() {
public void onClick(DialogInterface dialog, int whichButton) {
// Canceled.
}
});
alert.show();

Instead AlertDialog
you can use a custom dialog
Dialog dilog=new Dialog(this);
dilog.requestWindowFeature(Window.FEATURE_NO_TITLE);
dilog.setContentView(R.layout.yourlayout_in_xml);
and refer to its field
EditText youredittext=(EditText)dilog.findViewById(R.id.youredittext);
String textGet = youredittext.getText().toString(); // u will get ur inserted stting here
dilog.show() to show it
