I am taking data from a website and placing inside of a text view so that I can center it using setGravity(Gravity.CENTER). However when i place the text view inside of the alert dialog I can no longer scroll down to see the end of my message. Can someone help me with this problem? Thank You
TextView msg1=new TextView(Welcome.this);
//Takes data from a website
msg1.setText(Html.fromHtml(getText("http://www.cellphonesolutions.net/welcome-en")));
msg1.setGravity(Gravity.CENTER);
LinearLayout dialogLayout = new LinearLayout(Welcome.this);
dialogLayout.addView(msg1);
dialogLayout.setOrientation(LinearLayout.VERTICAL);
AlertDialog welcome = new AlertDialog.Builder(Welcome.this).create();
welcome.setView(dialogLayout);
welcome.setButton("OK", new DialogInterface.OnClickListener() {
#Override
public void onClick(DialogInterface dialog, int which) {
//rest of the code....
You can try changing the code like this:
dialogLayout.addView(msg1);
dialogLayout.setOrientation(LinearLayout.VERTICAL);
AlertDialog welcome = new AlertDialog.Builder(Welcome.this).create();
ScrollView scrollPane = new ScrollView(this);
scrollPane.addView(dialogLayout);
welcome.setView(scrollPane);

In this code, I am making an AlertDialog with attributes title, EditText, TextView, Cancel Button, and Email me Button.
EditText and TextView not aligned/set properly.
// Alert Dialog
private void showForgotpasswdDialog() {
AlertDialog.Builder builder = new AlertDialog.Builder(this);
builder.setTitle("Forgot your password?");
// Set linear layout
LinearLayout linearLayout = new LinearLayout(this);
// View to set an dialog
final EditText Email = new EditText(this);
Email.setHint("Email");
Email.setInputType(InputType.TYPE_TEXT_VARIATION_EMAIL_ADDRESS);
// Text view
linearLayout.addView(Email);
builder.setView(linearLayout);
// Text view
final TextView tv = new TextView(this);
tv.setText("Unfortunately, if you have never given us your email, we will not be able to reset your password");
linearLayout.addView(tv);
builder.setView(linearLayout);
// Buttons for EMAIL ME
builder.setPositiveButton("EMAIL ME", new
DialogInterface.OnClickListener() {
#Override
public void onClick(DialogInterface dialogInterface, int i) {
// Input email
String email = Email.getText().toString().trim();
beginforgotpasswd(email);
}
});
// Buttons for CANCEL
builder.setNegativeButton("CANCEL", new DialogInterface.OnClickListener() {
#Override
public void onClick(DialogInterface dialog, int i) {
// Dismiss dialog
dialog.dismiss();
}
});
// Show dialog
builder.create().show();
}
Please see the following screenshot showing the misaligned EditText:
just try it:
linearLayout.setOrientation(LinearLayout.VERTICAL);
to get proper orientation!
Hi I want to get user name and user gender using alert dialog so I add:
AlertDialog.Builder user= new AlertDialog.Builder(this);
user.setTitle("New Student");
user.setMessage("What is your Name?");
final RadioGroup genderRG= new RadioGroup(this);
RadioButton radiomr = new RadioButton(this);
radiomr.setText("Mr");
// radiomr.setId(1);
genderRG.addView(radiomr);
RadioButton radiomiss = new RadioButton(this);
radiomiss.setText("Miss");
// radiomiss.setId(2);
genderRG.addView(radiomiss);
user.setView(genderRG);
final EditText input = new EditText(this);
user.setView(input);
user.setPositiveButton("OK", new DialogInterface.OnClickListener()
{
#Override
public void onClick(DialogInterface dialog, int whichButton)
{
// get data
}
});
user.setNegativeButton("CANCEL", null);
user.create().show();
But when I run it, It just gives me an EditText.
Please! How can I get Gender and Name in same AlertDialog using radio button or spinner.
You should create your own layout and set it via setView().
You are instead inflating just the EditText, this is why you have just that in the dialog.
In any case it is better to use DialogFragment to create your own dialog version.

My problem is I have a button and that button is doing create new textview but that textviews removing when i click back button. How I saved textviews in activity?
My java sourcecodes here
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.notlar);
Button btnNotEkle = (Button) findViewById(R.id.btnNotEkle);
final EditText etNot = new EditText(NotEkle.this);
final LinearLayout layoutNotlar = (LinearLayout) findViewById(R.id.layoutNotlar);
final TextView tv1 = (TextView) findViewById(R.id.tvnotOrtalama);
etNot.setInputType(InputType.TYPE_CLASS_NUMBER);
AlertDialog.Builder notEkle = new AlertDialog.Builder(NotEkle.this);
notEkle.setTitle("Notunuz");
notEkle.setView(etNot);
//Positive button
notEkle.setPositiveButton("Tamam", new DialogInterface.OnClickListener() {
#Override
public void onClick(DialogInterface dialog, int which) {
tvNot = new TextView(NotEkle.this);//girelen not burdaki textview e yazdırılacak.
girilenNot = etNot.getText().toString();//Girilen notu alıyoruz
tvNot.setText(girilenNot);//girilen notu textviewa veriyoruz
notTopla += Integer.parseInt(girilenNot);//Notları topluyoruz
layoutNotlar.addView(tvNot);
count = layoutNotlar.getChildCount();
dersOrtalamaYazdir=String.valueOf(dersOrtalama());
tv1.setText("Ders Ortalamanız : "+dersOrtalamaYazdir);
dialog.cancel();
}
});
final AlertDialog notEkleCreate = notEkle.create();
btnNotEkle.setOnClickListener(new OnClickListener() {
#Override
public void onClick(View arg0) {
notEkleCreate.show();
}
});
}
}
Try giving your TextView objects ids.
You need to know that when you click back button - by default your activity is destroyed so all views are removed.
When you are adding new TextView you should add information about this TextView (like the text itself) to some list declared as field in your activity.
Then you can save this list when activity is recreated see: onSaveInstanceState/nRestoreInstanceState
You can also pass this list back or to new activity so that they can take actions based on this list.
Following my understanding your TextView had been created inside Dialog and after you press back button the dialog dismisses and all views you created inside will be removed and you can't access it from your Activity.
You may try to create TextView in onCreate, pass and in Dialog just call setText. I hope this is the answer you're looking for.
Cheers.
I have an AlertDialog for showing a small form to the user.
On the ALertDialog are 2 buttons; namely "Submit" & "Cancel".
Now the fields (EditTexts) have setKeyListeners attached to them individually.
The problem which I face is suppose the user doesn't fills in any field and directly clicks on Submit button then the dialog box closes automatically.
Here's my Method which is called for creating/showing the Dialog Box:
Context ctx = this.getApplicationContext();
LinearLayout layoutCreateMerch = new LinearLayout(ctx);
layoutCreateMerch.setOrientation(LinearLayout.VERTICAL);
layoutCreateMerch.setVerticalScrollBarEnabled(true);
final AlertDialog.Builder alert = new AlertDialog.Builder(Store.this);
alert.setTitle("New Store");
final EditText stoName = new EditText(Store.this);
final EditText stoDesc = new EditText(Store.this);
InputFilter[] FilterMaxLen = new InputFilter[1];
FilterMaxLen[0] = new InputFilter.LengthFilter(25);
stoName.setFilters(FilterMaxLen);
stoName.setHint("Store's Name");
stoName.setKeyListener(DigitsKeyListener.getInstance("abcdefghijklmnopqrstuvwxyzABCDEFGHIJKLMNOPQRSTUVWXYZ.,'1234567890 "));
stoName.setInputType(InputType.TYPE_TEXT_VARIATION_PERSON_NAME);
layoutCreateMerch.addView(stoName);
stoDesc.setFilters(FilterMaxLen);
stoDesc.setHint("Store's Description");
stoDesc.setKeyListener(DigitsKeyListener.getInstance("abcdefghijklmnopqrstuvwxyzABCDEFGHIJKLMNOPQRSTUVWXYZ.,'1234567890 "));
stoDesc.setInputType(InputType.TYPE_TEXT_VARIATION_PERSON_NAME);
layoutCreateMerch.addView(stoDesc);
ScrollView scroll = new ScrollView(ctx);
scroll.setBackgroundColor(Color.TRANSPARENT);
scroll.setLayoutParams(new LayoutParams(LayoutParams.FILL_PARENT, LayoutParams.FILL_PARENT));
scroll.addView(layoutCreateMerch);
alert.setView(scroll);
alert.setNeutralButton("Submit",
new DialogInterface.OnClickListener() {
public void onClick(DialogInterface dialog, int whichButton) {
if (Name.getText().toString().equals("")
|| Desc.getText().toString().equals(""))
{
if(stoName.getText().toString().equals("")){
stoName.setHint("fill Store's Name");
stoName.setHintTextColor(Color.RED);
}
else{}
if( stoDesc.getText().toString().equals("")){
stoDesc.setHint("fill Store's Description");
stoDesc.setHintTextColor(Color.RED);
}
else{}
if..
..
..
}
else {
System.out.println("should not exit :| ");
}
}
});
alert.setNegativeButton("Cancel",
new DialogInterface.OnClickListener() {
public void onClick(DialogInterface dialog,
int whichButton) {
dialog.cancel();
}
});
alert.show();
Any advice is appreciated..
Thanks
Add addTextChangedListener for your EditText and then always check user have entered any text or not as if not disable the submit button else enable the submit button dynamically.
Hi I've gone through all of the different linkify tutorials I could find but none of them work here is my current code:
final SpannableString s = new SpannableString("Please send any questions to email#fake.com");
Linkify.addLinks(s, Linkify.EMAIL_ADDRESSES);
AlertDialog.Builder builder = new AlertDialog.Builder(Activity.this);
builder.setTitle("Warning!")
.setMessage(s)
.setCancelable(false)
.setPositiveButton("Accept", new DialogInterface.OnClickListener() {
public void onClick(DialogInterface dialog, int id) {
}
})
.setNegativeButton("Decline", new DialogInterface.OnClickListener() {
public void onClick(DialogInterface dialog, int id) {
Activity.this.finish();
}
}).show();
However when I actually run the app it shows the text like blue and underlined as if it were linked but selecting the text doesn't prompt to open the email app. I've also tried with urls and the browser doesn't work is there something that's missing?
Thanks for any help.
In order to have a clickable area on dialog you need to use TextView (View) and set autoLink=all in layout file or invoke setAutoLinkMask() method from within the code.
final SpannableString s = new SpannableString("Please send any questions to email#fake.com");
//added a TextView
final TextView tx1=new TextView(this);
tx1.setText(s);
tx1.setAutoLinkMask(RESULT_OK);
tx1.setMovementMethod(LinkMovementMethod.getInstance());
Linkify.addLinks(s, Linkify.EMAIL_ADDRESSES);
AlertDialog.Builder builder = new AlertDialog.Builder(this);
builder.setTitle("Warning!")
.setCancelable(false)
.setPositiveButton("Accept", new DialogInterface.OnClickListener() {
public void onClick(DialogInterface dialog, int id) {
}
})
.setNegativeButton("Decline", new DialogInterface.OnClickListener() {
public void onClick(DialogInterface dialog, int id) {
finish();
}
})
.setView(tx1)
.show();
Here's Kotlin in case it's helpful:
val s = SpannableString(getString(R.string.actions_list_info_button_body))
val tx1 = TextView(context!!)
tx1.text = s
tx1.autoLinkMask = RESULT_OK
tx1.movementMethod = LinkMovementMethod.getInstance()
The rest is the same.
The result likely will not look great so you probably will want to add some padding as well:
// Adjust Padding to dp
val scale: Float = resources.displayMetrics.density
val dpAsPixels: Int = (25 * scale + 0.5f).toInt()
text.setPadding(dpAsPixels,20,dpAsPixels,0)
Alternatively, you can reuse the TextView created.
AlertDialog.Builder builder;
builder.setMessage(R.string.yourMessage);
Dialog dialog = builder.create();
dialog.setOnShowListener(d -> {
TextView text = dialog.getWindow().findViewById(android.R.id.message);
text.setAutoLinkMask(Linkify.ALL);
text.setMovementMethod(LinkMovementMethod.getInstance());
});
