How can can I add custom buttons into an AlertDialog's layout?

How can can I add custom buttons into an AlertDialog's layout? - android

I have AlertDialog with Positive and Negative buttons. In AlertDialog layout I have EditText and two Buttons (btnAdd1, btnAdd2). I want when user click at the Button btnAdd1 or btnAdd2 add same text to EditText in AlertDialog (but no close AlertDialog). Is this possible do in AlertDialog or I have to use only Dialog?
This is layout (R.layout.prompt) of AlertDialog:
<LinearLayout>
<EditText
android:id="#+id/userInput"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:inputType="text" >
<requestFocus />
</EditText>
<Button
android:id="#+id/btnAdd1"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="bla" />
<Button
android:id="#+id/btnAdd2"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="bla" />
</LinearLayout>
And this is source code:
LayoutInflater layoutInflater = LayoutInflater.from(this);
View promptView = layoutInflater.inflate(R.layout.prompt, null);
AlertDialog.Builder alertDialogBuilder = new AlertDialog.Builder(this);
alertDialogBuilder.setView(promptView);
alertDialogBuilder
.setCancelable(false)
.setPositiveButton("OK", new DialogInterface.OnClickListener() {
public void onClick(DialogInterface dialog, int id) {
//...
}
})
.setNegativeButton("Cancel",
new DialogInterface.OnClickListener() {
public void onClick(DialogInterface dialog, int id) {
dialog.cancel();
}
});
AlertDialog alertD = alertDialogBuilder.create();
alertD.show();
I want get acces to the btnAdd1 and btnAdd2 from the layout. Set the OnClickListener() to these two buttons.

The following code will inflate a view from R.layout.prompt and set it to the AlertDialog. The positive and negative buttons will not be used. You can set the onClick behaviors for btnAdd1 and btnAdd2:
LayoutInflater layoutInflater = LayoutInflater.from(this);
View promptView = layoutInflater.inflate(R.layout.prompt, null);
final AlertDialog alertD = new AlertDialog.Builder(this).create();
EditText userInput = (EditText) promptView.findViewById(R.id.userInput);
Button btnAdd1 = (Button) promptView.findViewById(R.id.btnAdd1);
Button btnAdd2 = (Button) promptView.findViewById(R.id.btnAdd2);
btnAdd1.setOnClickListener(new OnClickListener() {
public void onClick(View v) {
// btnAdd1 has been clicked
}
});
btnAdd2.setOnClickListener(new OnClickListener() {
public void onClick(View v) {
// btnAdd2 has been clicked
}
});
alertD.setView(promptView);
alertD.show();

what you want to do is;
alertD.show();
Button button = (Button)promptView.findViewById(R.id.buttonId);
button.setOnClickListener(....)
using the view to call findViewById, rather than the activity, which will look for the id in the layout that is being displayed.

According to this approach i am able to create the image button but if i want to dismiss or cancel dialog on Cancel button then what i have to do..
public static void alertDialogShow(final Context context,
final String resultMobile) {
LayoutInflater li = LayoutInflater.from(context);
View promptsView = li.inflate(R.layout.prompt,
null);
AlertDialog.Builder alertDialogBuilder = new AlertDialog.Builder(
context, AlertDialog.THEME_DEVICE_DEFAULT_LIGHT);
// set prompts.xml to alertdialog builder
alertDialogBuilder.setView(promptsView);
final EditText userInput = (EditText) promptsView
.findViewById(R.id.editTextDialogUserInput);
userInput.setText(resultMobile);
userInput.setEnabled(false);
btnCancel.setOnClickListener(new OnClickListener() {
#Override
public void onClick(View arg0) {
}
});

My solution for your question.
LayoutInflater layoutInflater = LayoutInflater.from(this);
View promptView = layoutInflater.inflate(R.layout.prompt, null);
AlertDialog.Builder alertDialogBuilder = new AlertDialog.Builder(this);
alertDialogBuilder.setView(promptView);
Button btn_1= (Button)promptView.findViewById(R.id.btnAdd1);
btn_1.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View view) {
//do required function
// don't forget to call alertD.dismiss()
}
});
Button btn_2 = (Button)promptView.findViewById(R.id.btnAdd2);
btn_2.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View view) {
//do required function
}
});
alertDialogBuilder
.setCancelable(false)
AlertDialog alertD = alertDialogBuilder.create();
alertD.show();

This is the way I did.

In activity file
LayoutInflater layoutInflater = getLayoutInflater();
View alertLayout = layoutInflater.inflate(R.layout.custom_alert_dialog, null);
Button button = alertLayout.findViewById(R.id.button1);
AlertDialog.Builder alertDialog = new AlertDialog.Builder(MainActivity.this);
alertDialog.setCancelable(false);
alertDialog.setView(alertLayout);
AlertDialog dialog = alertDialog.create();
button.setOnClickListener(new View.OnClickListener(){
#Override
public void onClick(View v) {
dialog.dismiss();
}
});
dialog.show();

You could try something like this :
dialog.setPositiveButton(R.string.positive, new DialogInterface.OnClickListener() {
#Override
public void onClick(DialogInterface dialogInterface, int i) {
dialog.show();
}
});

AlertDialog with CheckBox

In my application I have button to which displays an AlertDialog. The AlertDialog has a CheckBox. Now I have to call a function if the checkbox is checked, and a different function if its not checked.
AlertDialog.Builder builder = new AlertDialog.Builder(this,R.style.AlertDialogTheme);
builder.setTitle("Delete Completed Tasks:");
View view = getLayoutInflater().inflate(R.layout.del_completed,null);
builder.setView(view);
builder.setPositiveButton("Delete",
new DialogInterface.OnClickListener() {
#Override
public void onClick(DialogInterface dialogInterface, int i) {
CheckBox cb = findViewById(R.id.checkbox);
if(cb.isChecked()){
helper.delCompAndRec();
}
else helper.delCompleted();
}
});
builder.setNegativeButton("Cancel",new DialogInterface.OnClickListener(){
#Override
public void onClick(DialogInterface dialogInterface, int i) {
}
});
AlertDialog alert = builder.create();
alert.show();
}
The problem is I always get the cb.isChecked() value as False, even if its checked. How do I solve this?

AlertDialog.Builder builder = new AlertDialog.Builder(this,R.style.AlertDialogTheme);
builder.setTitle("Delete Completed Tasks:");
View view = getLayoutInflater().inflate(R.layout.del_completed,null);
final CheckBox cb = view.findViewById(R.id.checkbox); //or declare as global variable
builder.setView(view);
builder.setPositiveButton("Delete",
new DialogInterface.OnClickListener() {
#Override
public void onClick(DialogInterface dialogInterface, int i) {
if(cb.isChecked()){
helper.delCompAndRec();
}
else helper.delCompleted();
}
});
builder.setNegativeButton("Cancel",new DialogInterface.OnClickListener(){
#Override
public void onClick(DialogInterface dialogInterface, int i) {
}
});
AlertDialog alert = builder.create();
alert.show();
}

You need to define checkbox in your design xml. And then you can access that checkbox via view.findViewById(R.id.checkbox).
AlertDialog.Builder builder = new AlertDialog.Builder(this, R.style.Theme_AppCompat);
builder.setTitle("Delete completed task");
View view = getLayoutInflater().inflate(R.layout.del_completed, null);
final CheckBox cb = view.findViewById(R.id.checkbox); //like defined here
builder.setView(view);
builder.setPositiveButton("Delete", new DialogInterface.OnClickListener() {
#Override
public void onClick(DialogInterface dialogInterface, int i) {
if(cb.isChecked()){
helper.delCompAndRec();
}
else {
helper.delCompleted();
}
}
});
builder.setNegativeButton("Cancel", new DialogInterface.OnClickListener(){
#Override
public void onClick(DialogInterface dialogInterface, int i) {
}
});
AlertDialog alert = builder.create();
alert.show();
}
In xml declare like this
<androidx.constraintlayout.widget.ConstraintLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="wrap_content"
xmlns:app="http://schemas.android.com/apk/res-auto">

app:layout_constraintBottom_toBottomOf="parent"
app:layout_constraintStart_toStartOf="parent"
app:layout_constraintEnd_toEndOf="parent"
android:layout_margin="30dp"/>
<CheckBox
android:id="#+id/checkbox"
android:layout_width="wrap_content"

</androidx.constraintlayout.widget.ConstraintLayout>

In Custom action bar if we hide any icon that space need to used by other icons or text view in action bar

In my app I am using custom action bar. In that action bar I have 4 icons and 1 textview. For action bar I am using linear layout.
I have 4 activities in my app, each activity will have different action bar. If I open 1st activity one icon will set visibility gone. Every one of these activities will have different icons.
Question: My requirement is when icon is disable that space need to used by textview. I try everything but always space will end of the action bar I don't want that space.
Here is my code.

Custom_Actionbar_layout:-

android:weightSum="5">
<ImageView
android:layout_width="0dp"
android:layout_height="wrap_content"
android:layout_weight="1"
android:src="#drawable/ok"

</LinearLayout>
And my theme is <style name="AppTheme" parent="Theme.AppCompat.Light">
And text view is dynamically changed text it is given by user. If any one need more details I will update.

You're setting the value of the android:weightSum attribute of your LinearLayout to 5.
When you're removing a View from that layout (setting its visibility to View.GONE), the weightSum of your LinearLayout is still 5, but the actual sum of your Views is only 4, hence the empty space.
Removing the android:weightSum attribute from your LinearLayout should solve the problem:
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="horizontal" android:layout_width="match_parent"
android:layout_height="40dp">
<ImageView
android:layout_width="0dp"
android:layout_height="wrap_content"
android:layout_weight="1"
android:src="#drawable/ok"
android:id="#+id/cst_ok"/>
<TextView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_weight="1"
android:layout_gravity="center"
android:gravity="center"
android:text="Custom ActionBar"
android:id="#+id/cst_txt"
android:singleLine="false"
android:maxLines="2"/>
<ImageView
android:layout_width="0dp"
android:layout_height="wrap_content"
android:layout_weight="1"
android:src="#drawable/delete1"
android:id="#+id/cst_del"/>

android:layout_width="0dp"
android:layout_height="wrap_content"
android:layout_weight="1"

<ImageView

Hyperlink in string resource in AlertDialog

I have a large string and I need to add 2 hyperlinks. I did it, but it`s not clickable.
String:
<string name="freeasa"><![CDATA[<b><font color=#cc0022>text<font color=#2266bb> text </font></b> <br> text <a href=\'http://google.com\'>navigate to google.com</a><br><b><font color=#2266bb> text</font><font color=#cc0022> text </font></b><br> text <a href=\'http://yahoo.com\'> yahoo link<\a> ]]></string>
AlertDialog:
final AlertDialog.Builder builder = new AlertDialog.Builder(getContext());
builder.setTitle(getResources().getString(R.string.add_info));
builder.setMessage(Html.fromHtml(getResources().getString(R.string.freeasa)))
.setPositiveButton("OK", new DialogInterface.OnClickListener() {
#Override
public void onClick(DialogInterface dialogInterface, int i) {
dialogInterface.dismiss();
}
}).show();
There are hyperlinks, but they are not clickable. How to fix it ?

try custom alert dialog below way
LayoutInflater li = LayoutInflater.from(MainActivity.this);
View promptsView = li.inflate(R.layout.prompts, null);
final AlertDialog.Builder builder = new AlertDialog.Builder(MainActivity.this);
builder.setView(promptsView);
final TextView userInput = (TextView) promptsView
.findViewById(R.id.textView);
userInput.setMovementMethod(LinkMovementMethod.getInstance());
userInput.setText(Html.fromHtml(getResources().getString(R.string.about_body)));
builder.setTitle(getResources().getString(R.string.app_name));
// builder.setMessage(Html.fromHtml(getResources().getString(R.string.about_body)))
builder.setPositiveButton("OK", new DialogInterface.OnClickListener() {
#Override
public void onClick(DialogInterface dialogInterface, int i) {
dialogInterface.dismiss();
}
}).show();
prompts.xml
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical"
android:padding="10dip">
<TextView
android:id="#+id/textView"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:clickable="true"
android:text="Medium Text"
android:textAppearance="?android:attr/textAppearanceMedium" />
</LinearLayout>
make sure your string is correct and links are working

Use this to set an heperlink to a TextView:
TextView website = new TextView(this);
website.setText("http://www.google.com");
Linkify.addLinks(website, Linkify.ALL);
Hope it helps

View.OnClickListener in a custom DialogFragment

I am trying to implement a custom DialogFragment, following this tutorial. My problem is that I fail to handle my custom's view's button.setOnClickListener event. The strangest part is that I have no problem in geting the .getText() of my button, I just can't find a way to handle the click event. Bellow is my code:
SettingsDialogFragment.java
public class SettingsDialogFragment extends DialogFragment
{
#Override
public Dialog onCreateDialog(Bundle savedInstanceState)
{
AlertDialog.Builder builder = new AlertDialog.Builder(getActivity());
// Get the layout inflater
LayoutInflater inflater = getActivity().getLayoutInflater();
final View view = inflater.inflate(R.layout.dialog_settings, null);
final Button colorButton =(Button) view.findViewById(R.id.colorButton_dialogSettings);
String s = colorButton.getText().toString();
System.out.println("its working "+s);
//NOT working
colorButton.setOnClickListener(new View.OnClickListener()
{
#Override
public void onClick(View v)
{
System.out.println("OnClick");
}
});
// Inflate and set the layout for the dialog
// Pass null as the parent view because its going in the dialog layout
builder.setView(inflater.inflate(R.layout.dialog_settings, null))
// Add action buttons
.setPositiveButton(R.string.ok, new DialogInterface.OnClickListener() {
#Override
public void onClick(DialogInterface dialog, int id)
{
}
})
.setNegativeButton(R.string.cancel, new DialogInterface.OnClickListener() {
public void onClick(DialogInterface dialog, int id) {
SettingsDialogFragment.this.getDialog().cancel();
}
});
return builder.create();
}
`
My custom view code (dialog_settings.xml)
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="vertical"
android:layout_width="200dp"
android:layout_height="wrap_content">
<EditText
android:layout_width="match_parent"
android:layout_height="50dp"
android:gravity="center"
android:scaleType="center"
android:background="#00CCCC"
android:contentDescription="#string/app_name"
android:text="#string/dialog_settings_title"
android:id="#+id/editText"/>
<Button
android:id="#+id/colorButton_dialogSettings"
android:inputType="textEmailAddress"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:text="#string/color_picker_title"
android:layout_below="#+id/editText"
android:layout_alignParentLeft="true"
android:layout_alignParentStart="true"
/>
<RadioButton
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="Stroke"
android:layout_marginLeft="55dp"
android:id="#+id/radioButtonStroke"
android:checked="false"
android:layout_below="#+id/colorButton_dialogSettings"
android:layout_alignParentLeft="true"
android:layout_alignParentStart="true"/>
<RadioButton
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="Fill"
android:id="#+id/radioButton_fill"
android:checked="false"
android:layout_below="#+id/colorButton_dialogSettings"
android:layout_toRightOf="#+id/radioButtonStroke"
android:layout_toEndOf="#+id/radioButtonStroke"
android:layout_marginLeft="10dp"
/>

I am just showing you the important part.. i hope you find their respective lines in your code
final View view = inflater.inflate(R.layout.dialog_settings, null);
// inflating your view..for drawback, this line is [A]
your colorButton has a reference to view.findViewById(R.id.colorButton_dialogSettings) which is from the viewgroup view..which you reference an onclick listener for it..
builder.setView(inflater.inflate(R.layout.dialog_settings, null))
this code right here sets the content view for your dialog. it inflates a the layout and does it's work.. so in the end your builder is not referencing it's content view to view but a new inflated R.layout.dialog_settings layout..
so to solve it just do this
builder.setView(view) // hope you know the view parameter
the view is what you instantiated at line [A] ..
Hope i made sense, and lucid enough for you..let me know if it helps

New Answer
Change your onCreateDialog to this:
import android.view.View.OnClickListener;
public class SettingsDialogFragment extends DialogFragment implements onClickListener
{
#Override
public Dialog onCreateDialog(Bundle savedInstanceState)
{
AlertDialog.Builder builder = new AlertDialog.Builder(getActivity());
// Get the layout inflater
LayoutInflater inflater = getActivity().getLayoutInflater();
final View view = inflater.inflate(R.layout.dialog_settings, null);
final Button colorButton =(Button) view.findViewById(R.id.colorButton_dialogSettings);
String s = colorButton.getText().toString();
System.out.println("its working "+s);
colorButton.setOnClickListener(new View.OnClickListener()
{
#Override
public void onClick(View v)
{
switch (v.getId()) {
case R.id.colorButton_dialogSettings
System.out.println("OnClick");
break;
default:
break;
}
});
// Inflate and set the layout for the dialog
// Pass null as the parent view because its going in the dialog layout
builder.setView(inflater.inflate(R.layout.dialog_settings, null))
// Add action buttons
.setPositiveButton(R.string.ok, new DialogInterface.OnClickListener() {
#Override
public void onClick(DialogInterface dialog, int id)
{
}
})
.setNegativeButton(R.string.cancel, new DialogInterface.OnClickListener() {
public void onClick(DialogInterface dialog, int id) {
SettingsDialogFragment.this.getDialog().cancel();
}
});
return builder.create();
}
In your activity:
private Button colorButton = (Button) findViewById(R.id.colorButton_dialogSettings);
**Old answer that requires you to write your own showDialog method**
Try deleting your button code in the onCreateDialog and add this:
#Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
View v = inflater.inflate(R.layout.fragment_dialog, container, false);
Button colorButton =(Button) v.findViewById(R.id.colorButton_dialogSettings);
public void onClick(View v) {
// When button is clicked, call up to owning activity.
((FragmentDialog)getActivity()).showDialog();
System.out.println("OnClick");
}
});
return v;

How to get value of textfield in alertdialog with custom layout

This is my layout for the dialog :-
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent" android:layout_height="wrap_content"
>
<EditText
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:inputType="date"
android:ems="10"
android:id="#+id/date"
android:layout_weight="1" />
</LinearLayout>
I call the dialog from a class extending android.support.v4.app.Fragment. Here is my class extending DialogFragment:-
public static class MyDialogFragment extends DialogFragment {
#Override
public Dialog onCreateDialog(Bundle savedInstanceState) {
AlertDialog.Builder builder = new AlertDialog.Builder(getActivity());
LayoutInflater inflater = getActivity().getLayoutInflater();
builder.setView(inflater.inflate(R.layout.date_settings, null));
builder.setPositiveButton("Ok", new DialogInterface.OnClickListener() {
public void onClick(DialogInterface dialog, int id) {
try {
//The problem starts
//How do I get the reference to the EditText
}catch (Exception e){
e.printStackTrace();
}
}
});
return builder.create();
}
}
I call the MyDialogFragment from my class as follows:-
MyDialogFragment dial = new MyDialogFragment();
dial.show(getActivity().getSupportFragmentManager(),"tag");
Now, How do I get the text in the EditText ?

use dialog for getting text from EditText which is in AlertDialog:
public void onClick(DialogInterface dialog, int id) {
try {
EditText editdate = (EditText) ((Dialog)
dialog).findViewById(R.id.date);
}catch (Exception e){
e.printStackTrace();
}
}
or you can also do it using inflated view :
View view = inflater.inflate(R.layout.date_settings, null);
builder.setView(view);
....
EditText editdate = (EditText)view.findViewById(R.id.date);

First you need to give id of EditText
<EditText
android:id="#+id/txtDate"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:inputType="date"
android:ems="10"
android:id="#+id/date"
android:layout_weight="1" />
Do some changes in code like following:
public static class MyDialogFragment extends DialogFragment {
#Override
public Dialog onCreateDialog(Bundle savedInstanceState) {
AlertDialog.Builder builder = new AlertDialog.Builder(getActivity());
LayoutInflater inflater = getActivity().getLayoutInflater();
View v = inflater.inflate(R.layout.date_settings, null);
builder.setView(v);
EditText txtDate = (EditText) v.findViewById(R.id.txtDate);
txtDate.setText("Ben Lind");
builder.setPositiveButton("Ok", new DialogInterface.OnClickListener() {
public void onClick(DialogInterface dialog, int id) {
try {
//The problem starts
//How do I get the reference to the EditText
}catch (Exception e){
e.printStackTrace();
}
}
});
return builder.create();
}
}

How can can I add custom buttons into an AlertDialog's layout? - android

what you want to do is; alertD.show(); Button button = (Button)promptView.findViewById(R.id.buttonId); button.setOnClickListener(....) using the view to call findViewById, rather than the activity, which will look for the id in the layout that is being displayed.

You could try something like this : dialog.setPositiveButton(R.string.positive, new DialogInterface.OnClickListener() { #Override public void onClick(DialogInterface dialogInterface, int i) { dialog.show(); } });
