This code is to open a dialog in OnPostExecute functions, and it works perfect.
The problem:
In the layout popup, which appears in the dialog, I have a imageview which I place him a URL to show me the picture of that url, the idea is to assign that url when creating the dialog, ie dynamically.
How could I do this?
Thanks for the help
#Override
protected void onPostExecute(String result) {
//Toast.makeText(context, result.toString(), Toast.LENGTH_LONG).show();
/*nombre.setText("");
dni.setText("");
telefono.setText("");
email.setText("");*/
AlertDialog.Builder builder = new AlertDialog.Builder(getActivity());
LayoutInflater inflater = getActivity().getLayoutInflater();
builder.setView(inflater.inflate(R.layout.popup, null))
.setPositiveButton("Aceptar", new DialogInterface.OnClickListener() {
public void onClick(DialogInterface dialog, int id) {
dialog.cancel();
}
});
builder.create();
builder.show();
}
You have to declare the Dialog layout View and the ImageView inside it before inflating it. Like this:
//inside onPostExecute()
AlertDialog.Builder builder = new AlertDialog.Builder(getActivity());
LayoutInflater inflater = getLayoutInflater();
View imageLayoutView = inflater.inflate(R.layout.popup, null);
ImageView image = (ImageView) imageLayoutView.findViewById(R.id.yourImageViewId);
//an URI example
Uri uri = Uri.parse("content://media/external/images/media/123");
image.setImageURI(uri);
builder.setView(imageLayoutView)
.setPositiveButton("Aceptar", new DialogInterface.OnClickListener() {
public void onClick(DialogInterface dialog, int id) {
dialog.cancel();
}
});
builder.create();
builder.show();
Using this code, you set the Uri to the ImageView dynamically.

I'm having a custom layout xml file named login_form with a LinearLayout root named login_form_root. I'm trying to display this layout using dialog but can't get values from EditText as I get cannot resolve method findViewById inside onCreateDialog.
AlertDialog.Builder builder = new AlertDialog.Builder(getActivity());
final LayoutInflater inflater = getActivity().getLayoutInflater();
builder.setView(inflater.inflate(R.layout.login_form, null));
builder.setPositiveButton(okText, new DialogInterface.OnClickListener() {
#Override
public void onClick(DialogInterface dialog, int which) {
View myView = inflater.inflate(R.layout.login_form, (ViewGroup) findViewById(R.id.login_form_root));
EditText userEmail = (EditText) myView.findViewById(R.id.email_address);
userEmailValue = userEmail.getText().toString();
Toast.makeText(getActivity(), userEmailValue, Toast.LENGTH_SHORT).show();
}
Error is here:-
"(ViewGroup) findViewById(R.id.login_form_root)"
so how can I inflate the custom layout to get EditText values?
You should save the View when inflate it, then you can use it later
AlertDialog.Builder builder = new AlertDialog.Builder(getActivity());
LayoutInflater layoutInflater = LayoutInflater.from(getActivity());
final View view = layoutInflater.inflate(R.layout.login_form, null);
builder.setView(view);
AlertDialog dialog = builder.create();
builder.setPositiveButton("OK", new DialogInterface.OnClickListener() {
#Override
public void onClick(DialogInterface dialog, int which) {
EditText userEmail = (EditText) view.findViewById(R.id.email_address);
String userEmailValue = userEmail.getText().toString();
}
});
I coded like below for creating a alertdialog . alert box works properly but how can I add image into alertbox?? while the title and messages ared parsed strings from my database.I need to add image from database dynamically.
private AlertDialog.Builder builder;
public void onClick(View v) {
builder = new AlertDialog.Builder(ProfileViewActivity.this).setTitle(ser_name)
.setMessage(desc);
builder.setPositiveButton("Close", new DialogInterface.OnClickListener() {
#Override
public void onClick(DialogInterface dialog, int which) {
dialog.cancel();
}
}).show();
Inflate layout to you alertbox
AlertDialog.Builder dialogBuilder = new AlertDialog.Builder(this);
LayoutInflater inflater = this.getLayoutInflater();
View dialogView = inflater.inflate(R.layout.alert_label_editor, null);
dialogBuilder.setView(dialogView);
ImageView imgview = (ImageView) dialogView.findViewById(R.id.img);
imgview.setResource(R.drawable.img);
AlertDialog alertDialog = dialogBuilder.create();
alertDialog.show();
make you own layout
Im trying to get the content of the editText, but idont know how to do it. Please help me in this.(Im using the method showDialog)
protected Dialog onCreateDialog(int id, Bundle args)
{
AlertDialog.Builder builder2 = new AlertDialog.Builder(this);
LayoutInflater inflater = this.getLayoutInflater();
builder2.setView(inflater.inflate(R.layout.dialog_search_teacher,null));
final EditText price,city;
price=(EditText)findViewById(R.id.price_search);
city=(EditText)findViewById(R.id.city_search);
builder2.setPositiveButton("Serach", new DialogInterface.OnClickListener() {
#Override
public void onClick(DialogInterface dialog, int which) {
serach(city.getText().toString(),price.getText().toString());
}
});
builder2.setNegativeButton("Cancel", new DialogInterface.OnClickListener() {
#Override
public void onClick(DialogInterface dialog, int which) {
}
});
AlertDialog alert2 = builder2.create();
return(alert2);}
If you need to get the text from the EditText you have to do this:
LayoutInflater inflater = getActivity().getLayoutInflater();
View view = inflater.inflate(R.layout.dialog_search_teacher, null);
city=(EditText)view.findViewById(R.id.city_search);
and then, on the onclick() method you have to retrieve the text:
city.getText().toString();
but if you want to pass the string to the parent class you have to do an interface like this:
http://developer.android.com/training/basics/fragments/communicating.html
You have to find editText id like this
price=(EditText)builder2.findViewById(R.id.price_search);
You should declaration your editText under the dialog method like,
LayoutInflater inflater = getActivity().getLayoutInflater();
View view = inflater.inflate(R.layout.dialog_search_teacher, null);
city=(EditText)view.findViewById(R.id.city_search);
After that, while doing onClick listener for postive button, you can get the content of editText using
city.getText().toString();
Hope this will help you.
I have the following AlertDialog and its onClick method:
final AlertDialog.Builder alertDialog = new AlertDialog.Builder(this);
alertDialog.setView(View.inflate(this, R.layout.barcode_alert, null));
alertDialog.setPositiveButton("Search", new DialogInterface.OnClickListener() {
#Override
public void onClick(#NotNull DialogInterface dialog, int which) {
// how to get editTextField.getText().toString(); ??
dialog.dismiss();
}
});
The XML I inflate in the dialog (barcode_alert.xml) contains, among other things, an EditText field, and I need to get its string value after the user taps the Search button.
My question is, how do I get a reference to that field so I can get its text string?
final AlertDialog.Builder alertDialog = new AlertDialog.Builder(this);
final View v = View.inflate(this, R.layout.barcode_alert, null); //here
alertDialog.setView(v);
alertDialog.setPositiveButton("Search", new DialogInterface.OnClickListener() {
#Override
public void onClick(#NotNull DialogInterface dialog, int which) {
((EditText)v.findViewById(R.id.edit_text)).getText().toString(); //and here
dialog.dismiss();
}
});
Try this,
final AlertDialog.Builder alertDialog = new AlertDialog.Builder(this);
final View v = getLayoutInflater().inflate(this, R.layout.barcode_alert, null);
final EditText editTextField = (EditText) v.findViewById(R.id.edit_text);
editTextField.setOnClickListener(MyActivity.this);
alertDialog.setView(v);
alertDialog.setPositiveButton("Search", new DialogInterface.OnClickListener() {
#Override
public void onClick(#NotNull DialogInterface dialog, int which) {
String enteredValue = editTextField.getText().toString(); // get the text from edit text
dialog.dismiss();
}
});
You can inflate your view and get a reference to a variable:
View v = View.inflate(this, R.layout.barcode_alert, null);
you can use findViewById to get a reference to your view. Make sure that your variable is final or a member variable. Otherwise you cannot access it in the onClickListener
final EditText editText = (EditText)v.findViewById(R.id.your_edit_text
I have created a Custom AlertDialog and I'm trying to set text for EditTexts. I have tried following
public class CheckListDialog extends DialogFragment {
private View view;
public CheckListDialog(View view) {
this.view = view;
}
#Override
public AlertDialog onCreateDialog(Bundle savedInstanceState) {
LayoutInflater inflater = getActivity().getLayoutInflater();
View dialogLayout = inflater.inflate(R.layout.dialog_checklist, null);
EditText etCost = (EditText) dialogLayout.findViewById(R.id.etCost);
EditText etOdoReading = (EditText) dialogLayout.findViewById(R.id.etOdometer);
etOdoReading.setText("bla");
etCost.setText("tada");
AlertDialog.Builder builder = new AlertDialog.Builder(new ContextThemeWrapper(Reminders.this, android.R.color.transparent));
builder.setView(inflater.inflate(R.layout.dialog_checklist, null))
.setTitle("jaja")
.setPositiveButton("Add", new DialogInterface.OnClickListener() {
#Override
public void onClick(DialogInterface dialog, int id) {
}
})
.setNegativeButton("Cancel", new DialogInterface.OnClickListener() {
public void onClick(DialogInterface dialog, int id) {
}
});
return builder.create();
}
}
The EditTexts are empty and does not contain the values. How can i fix this?
Replace
builder.setView(inflater.inflate(R.layout.dialog_checklist, null))
with
builder.setView(dialogLayout)
You're modifying the edittexts in one layout and then inflating a new layout for the dialog.
For such operations you have to use a custom layout to inflate into the CheckListDialog class of yours. DialogFragment will provide you complete freedom to customize your dialog as per your requirement.
