I have an Activity which launches an AlertDialog with the following code. Unfortunately, the id that comes from the RadioGroup as checked is always the ID of the first radio button, no matter which radio button was actually checked.
I suspect the problem is that the view has already been disposed of when the OK button is pressed, but I don't know why the string would still work if that were the case.
Why would this happen, and what could I do to get the actual radio button checked?
AlertDialog.Builder builder = new AlertDialog.Builder(this);
final View v = getLayoutInflater().inflate(R.layout.dialog_add_team, null);
builder.setView(v);
// Add the buttons
builder.setPositiveButton(R.string.ok,
new DialogInterface.OnClickListener() {
public void onClick(DialogInterface dialog, int id) {
String name = ((EditText) v.findViewById(R.id.team_name)).getText()+"";
if (name.equals(""))
return;
int checkedId=((RadioGroup)v.findViewById(R.id.radioGroup1))
.getCheckedRadioButtonId();
teamAdded(name, checkedId);
}
});
builder.setNegativeButton(R.string.cancel,
new DialogInterface.OnClickListener() {
public void onClick(DialogInterface dialog, int id) {
// User cancelled the dialog
}
});
AlertDialog dialog = builder.create();
dialog.show();
}
Here is the XML for my layout:
<?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" >
<EditText
android:id="#+id/team_name"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:ems="10"
android:hint="#string/teamname" >
<requestFocus />
</EditText>
<RadioGroup
android:id="#+id/radioGroup1"
android:layout_width="wrap_content"
android:layout_height="wrap_content" >
<RadioButton
android:id="#+id/radio0"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:checked="true"
android:text="#string/bothgenders" />
<RadioButton
android:id="#+id/radio1"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="#string/boys" />
<RadioButton
android:id="#+id/radio2"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="#string/girls" />
</RadioGroup>
</LinearLayout>
I think you should set setOnCheckedChangeListener to your radioGroup. You can use this answer. Hope this helps.

I added an Action button to show about Alert Dialog for my app that I'm developing.... I just fetched one xml file for that Action Dialog popup.
I used this xml as Alert Dialog popup. using below java code.
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="vertical"
android:layout_width="300dp"
android:layout_height="300dp"
android:weightSum="1">
<TextView
android:id="#+id/info"
android:layout_width="277dp"
android:layout_height="wrap_content"
android:text="Click the links below to contact us"
android:layout_marginTop="13dp"
android:layout_alignParentTop="true"
android:layout_centerHorizontal="true" />
<TextView
android:id="#+id/wa"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="#string/wa"
android:textSize="30dp"
android:layout_marginTop="8dp"
android:layout_below="#+id/info"
android:layout_centerHorizontal="true" />
<TextView
android:id="#+id/fb"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="#string/fb"
android:textSize="30dp"
android:layout_marginTop="8dp"
android:layout_below="#+id/wa"
android:layout_centerHorizontal="true" />
</RelativeLayout>
java code :
public void info(MenuItem item) {
View v = LayoutInflater.from(MainActivity.this).inflate(R.layout.alertdiag, null);
TextView waf = (TextView) findViewById(R.id.wa);
TextView fbf = (TextView) findViewById(R.id.fb);
AlertDialog.Builder builder = new AlertDialog.Builder(MainActivity.this);
builder.setMessage("About");
builder.setView(v);
builder.setCancelable(false);
builder.setPositiveButton("Okay", new DialogInterface.OnClickListener() {
#Override
public void onClick(DialogInterface dialog, int which) {
dialog.cancel();
}
});
builder.show();
Now I can see those TextViews in my main activity as alert Dialog. But I can't click the links. Any solution????
Thank you in advance.....
Use AlertDialog.setView() to display a custom layout containing your hyperlink TextView in the message area.
E.g. Make a hyperlink_layout.xml containing a TextView with id = hyperlink_text
I wonder how to click a Button inside of AlertDialog in Android and this is my code
activity_float_info.xml
<Button
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="New Button"
android:id="#+id/button" />
MainActivity.java
QR_ = LayoutInflater.from(MainActivity.this).inflate(R.layout.activity_float_info, null);
MAIN_QR_SCAN = (LinearLayout) findViewById(R.id.MAIN_QR_SCAN);
MAIN_QR_SCAN.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View view) {
new AlertDialog.Builder(MainActivity.this)
.setCancelable(Boolean.TRUE)
.setNegativeButton(getString(R.string.CANCEL), new DialogInterface.OnClickListener() {
#Override
public void onClick(DialogInterface dialogInterface, int i) {
dialogInterface.dismiss();
}
})
.setView(R.layout.activity_float_info)
.show();
button = (Button)QR_.findViewById(R.id.button);
button.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View view) {
button.setText("TEst");
}
});
}
});
I have inflate the layout..
I think the main problem is on
button = (Button)QR_.findViewById(R.id.button);
try this create a layout for dialog box
<TextView android:id="#+id/dialogtitle"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:gravity="center"
android:textColor="#android:color/black"
android:text="Please enter the email address you used for the account"
/>
<EditText
android:id="#+id/emailedittext"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:layout_margin="10dp"
android:ems="10"
android:padding="5dp"
android:cursorVisible="true"
android:singleLine="true"
android:background="#android:color/white"
android:textColor="#android:color/black"
android:hint="Enter Mail id"
android:textSize="20dp" >
<requestFocus />
</EditText>
<LinearLayout android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:weightSum="2"
android:orientation="horizontal">
<Button
android:id="#+id/cancelbtn"
android:layout_width="0dp"
android:layout_weight="1"
android:layout_height="wrap_content"
android:text="CANCEL"/>
<Button
android:id="#+id/okbtn"
android:layout_width="0dp"
android:layout_weight="1"
android:layout_height="wrap_content"
android:text="Ok"/>
</LinearLayout>
Then create a dialog box using this layout and handle button clicks
final Dialog dialog = new Dialog(MainActivity.this);
// Include dialog.xml file
dialog.setContentView(R.layout.forgotpassword);
// Set dialog title
dialog.setTitle("ALERT!!");
// set values for custom dialog components - text, image and button
Button okbtn = (Button) dialog.findViewById(R.id.okbtn);
Button cancelbtn = (Button) dialog.findViewById(R.id.cancelbtn);
final EditText emailedittext = (EditText) dialog.findViewById(R.id.emailedittext);
dialog.show();
dialog.getWindow().setSoftInputMode(
WindowManager.LayoutParams.SOFT_INPUT_STATE_ALWAYS_VISIBLE);
// if decline button is clicked, close the custom dialog
cancelbtn.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
// Close dialog
dialog.dismiss();
}
});
okbtn.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
String email=emailedittext.getText().toString();
//do something more here
}
});

Here is a hack to use AlertDialog:
public class CustomDialog extends AlertDialog {
protected CustomDialog(Context context) {
super(context);
}
}
And then in your Activity:
CustomDialog dialog = new CustomDialog(this);
View view = getLayoutInflater().inflate(R.layout.custom_dialog_layout,null);
dialog.setView(view);
Button button = (Button)view.findViewById(R.id.custom_button);
button.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
Toast.makeText(YourActivity.this,"Your message", Toast.LENGTH_LONG).show();
}
});
dialog.show();
And the layout of the dialog (which has nothing in it barring the Button):
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent">
<Button
android:id="#+id/custom_button"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_centerInParent="true"
android:text="New Button" />
</RelativeLayout>
And you should be able to see a Toast when you click on the button. Hope this helps.
Dialog is like a popup window to show some options to users(options like accept/decline).
Using class android.app.Dialog to create dialog.
Using dialog.xml file to create custom dialog layout.
Example:
res/layout/dialog.xml
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="fill_parent" >
<ImageView
android:id="#+id/imageDialog"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_marginRight="6dp" />
<TextView
android:id="#+id/textDialog"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:textColor="#FFF"
android:layout_toRightOf="#+id/imageDialog"/>
<Button
android:id="#+id/declineButton"
android:layout_width="100px"
android:layout_height="wrap_content"
android:text=" Submit "
android:layout_marginTop="5dp"
android:layout_marginRight="5dp"
android:layout_below="#+id/textDialog"
android:layout_toRightOf="#+id/imageDialog"
/>
</RelativeLayout>
Java Code
// Create custom dialog object
final Dialog dialog = new Dialog(CustomDialog.this);
// Include dialog.xml file
dialog.setContentView(R.layout.dialog);
// Set dialog title
dialog.setTitle("Custom Dialog");
// set values for custom dialog components - text, image and button
TextView text = (TextView) dialog.findViewById(R.id.textDialog);
text.setText("Custom dialog Android example.");
ImageView image = (ImageView) dialog.findViewById(R.id.imageDialog);
image.setImageResource(R.drawable.image0);
dialog.show();
Button declineButton = (Button) dialog.findViewById(R.id.declineButton);
// if decline button is clicked, close the custom dialog
declineButton.setOnClickListener(new OnClickListener() {
#Override
public void onClick(View v) {
// Close dialog
dialog.dismiss();
}
});
I've encountered a lot of pop up images like the example below, i've made a pop up image but there is no close button at the top left corner, do u guys have any idea how to make a pop up image with close button at the top left cornel like the example below in Android?
You need to make your own Dialog with your custom layout
Dialog dialog;
private void showDialog() {
// custom dialog
dialog = new Dialog(this);
dialog.setContentView(R.layout.custom_dialog);
// set the custom dialog components - text, image and button
ImageButton close = (ImageButton) dialog.findViewById(R.id.btnClose);
Button buy = (Button) dialog.findViewById(R.id.btnBuy);
// Close Button
close.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
dialog.dismiss();
//TODO Close button action
}
});
// Buy Button
buy.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
dialog.dismiss();
//TODO Buy button action
}
});
dialog.getWindow().setBackgroundDrawable(new ColorDrawable(Color.TRANSPARENT));
dialog.show();
}
custom_dialog.xml
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="wrap_content"
android:layout_height="wrap_content">
<LinearLayout
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_margin="20dp"
android:background="#android:color/white"
android:orientation="vertical">
<ImageView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:background="#drawable/images" />
<RelativeLayout
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_marginTop="10dp">
<Button
android:id="#+id/btnBuy"
android:layout_width="80dp"
android:layout_height="40dp"
android:layout_alignParentRight="true"
android:layout_alignParentTop="true"
android:background="#android:color/holo_green_light"
android:text="BUY"
android:textColor="#android:color/white" />
<TextView
android:id="#+id/txtTitle"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_toLeftOf="#+id/btnBuy"
android:text="Thank You (Domestic Album Version)"
android:textColor="#android:color/black"
android:textStyle="bold" />
<TextView
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_below="#+id/txtTitle"
android:text="Still Not Gettin' Any, 2004" />
</RelativeLayout>
</LinearLayout>
<ImageButton
android:id="#+id/btnClose"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignParentLeft="true"
android:layout_alignParentTop="true"
android:background="#android:color/black"
android:src="#android:drawable/ic_menu_close_clear_cancel" />
</RelativeLayout>
Result is:
You can use this library. There is close button on top right corner. only need to set image only.

I sought numerous answers/similar questions and non solved my problem. I have a custom dialog implemented in a class that extends "DialogFragment". When I try to get text from any of the layout components I get the initial default text that I sat.
Code snippet :
public class input1_frag extends DialogFragment
{
View v;
LayoutInflater inflater;
EditText email_field,passwd_field;
#Override
public Dialog onCreateDialog(Bundle savedInstanceState)
{
AlertDialog.Builder builder = new AlertDialog.Builder(getActivity());
inflater = getActivity().getLayoutInflater();
builder.setTitle("Identity verification");
// Inflate and set the layout for the dialog
builder.setView(inflater.inflate(R.layout.input_dialog, null));
builder.setPositiveButton("Modify account", new DialogInterface.OnClickListener()
{
public void onClick(DialogInterface dialog, int id)
{
v = inflater.inflate(R.layout.input_dialog, null);
email_field = (EditText) v.findViewById(R.id.input_dialog_email0);
passwd_field = (EditText) v.findViewById(R.id.input_dialog_passwd0);
String fetched_email = email_field.getText().toString();
String fetched_passwd = passwd_field.getText().toString();
});}}
input.dialog.xml

I made the view & the inflater global to avoid making them final. Yet it still returns the initial text from the textfield.
Remove following line from your onClick method and use it in builder.setView(). Because of this line view is being reset to its original form and changes made to edit text is lost.
v = inflater.inflate(R.layout.input_dialog, null);
Like this
AlertDialog.Builder builder = new AlertDialog.Builder(getActivity());
inflater = getActivity().getLayoutInflater();
builder.setTitle("Identity verification");
// Inflate and set the layout for the dialog
v = inflater.inflate(R.layout.input_dialog, null);
builder.setView(v);
builder.setPositiveButton("Modify account", new DialogInterface.OnClickListener()
{
public void onClick(DialogInterface dialog, int id)
{
email_field =
...
...
I have a button that brings up a dialog with an OK button, and I'm getting a nullpointerexception when I click on the OK button. Does anyone know what's wrong?
Here's my java code.
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.mylist);
myListView = (ListView)findViewById(R.id.list);
new GetStuff().execute();
Button importButton = (Button)findViewById(R.id.doButton);
importButton.setEnabled(false);
importButton.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
// TODO Auto-generated method stub
final Dialog pwdDialog = new Dialog(context);
pwdDialog.setContentView(R.layout.pwdentry);
pwdDialog.setTitle("Enter password");
TextView pwdText = (TextView)pwdDialog.findViewById(R.id.pwdText);
pwdText.setText("Enter password");
Button okBut = (Button)findViewById(R.id.okBut);
okBut.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
pwdDialog.dismiss();
}
});
pwdDialog.show();
}
});
}
Here's the XML file
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:orientation="vertical" >
<TextView
android:id="#+id/pwdText"
android:layout_width="fill_parent"
android:layout_height="50dip"
android:layout_alignParentLeft="true"
android:layout_alignParentRight="true"
android:layout_alignParentTop="true"
android:text="Enter password"
android:textAppearance="?android:attr/textAppearanceMedium" />
<EditText
android:id="#+id/pwdEntry"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignParentLeft="true"
android:layout_alignParentRight="true"
android:layout_below="#+id/pwdText"
android:ems="10"
android:inputType="numberPassword" >
<requestFocus />
</EditText>
<Button
android:id="#+id/okBut"
style="?android:attr/buttonStyleSmall"
android:layout_width="100px"
android:layout_height="wrap_content"
android:layout_below="#+id/pwdEntry"
android:layout_centerHorizontal="true"
android:layout_marginTop="5dp"
android:layout_marginRight="5dp"
android:text="OK" />
</RelativeLayout>
Thanks!
The problem is okBut will be null
Button okBut = (Button)findViewById(R.id.okBut);
you need to make this as
Button okBut = (Button)pwdDialog.findViewById(R.id.okBut);
Here you are retrieving a Button by using the id, R.id.okBut from your main layout R.layout.mylist.
Button okBut = (Button)findViewById(R.id.okBut);
