Android AlertDialog title font

I am trying to change the font of android.support.v7.app.AlertDialogtitle text.
METHOD 1 :
TextView title = (TextView) dialog.findViewById(android.R.id.title); //returns null
METHOD 2 :
final int titleId = context.getResources().getIdentifier("alertTitle", "id", "android");
TextView title = (TextView) dialog.findViewById(titleId); //Also returns null.
Is there any other way to get the title TextView?
Please note I do not want to use a custom layout.
Thanks.

I got it to work using this solution :
final AlertDialog.Builder alertBuilder = new AlertDialog.Builder(context);
Typeface tf = //get the typeface.
CustomTFSpan tfSpan = new CustomTFSpan(tf);
SpannableString spannableString = new SpannableString(title);
spannableString.setSpan(tfSpan, 0, spannableString.length(), Spannable.SPAN_EXCLUSIVE_EXCLUSIVE);
alertBuilder.setTitle(spannableString);
AlertDialog dialog = alertBuilder.create();
dialog.show();
CustomTFSpan
public class CustomTFSpan extends TypefaceSpan {
private Typeface typeface;
public CustomTFSpan(Typeface typeface) {
super("");
this.typeface = typeface;
}
#Override
public void updateDrawState(TextPaint ds) {
applyTypeFace(ds, typeface);
}
#Override
public void updateMeasureState(TextPaint paint) {
applyTypeFace(paint, typeface);
}
private static void applyTypeFace(Paint paint, Typeface tf) {
paint.setTypeface(tf);
}
}

Use this one
TextView title = (TextView) dialog.findViewById(R.id.alertTitle);
Without any custom title :)

Your question has already answer here : Change Title Font Of Alert Dialog Box Android
You can simply use a textview and set it as custom title like this : builder.setCustomTitle(tv2);

Create a simple TextView
TextView tv;
And replace
builder.setTitle("My Title");
with
builder.setCustomTitle(tv);

How to animate textview text in Android

I made animation for background colors of the text views like these:
final TextView textView1 =
(TextView)findViewById(R.id.leftleft);
Resources res = getResources();
final TransitionDrawable crossfaderView1 =
getTransitionDrawableFromColors(R.color.green, R.color.lime);
textView1.setBackground(crossfaderView1);
chooseChangeColors.setOnClickListener(
new View.OnClickListener()
{
#Override
public void onClick(View v) {
if (somethingElseIsPressed == true) {
crossfaderView1.reverseTransition(timeForTransition);
}
else {
crossfaderView1.startTransition(timeForTransition);
}
somethingElseIsPressed = !somethingElseIsPressed;
}
});
But I want to make text in these textViews also changing its own color and text itself.
How can I achieve this?

Set Text for pop up

I have a button with the onClick name of checkResult.
public void checkResult(View view){
LayoutInflater layoutInflater = (LayoutInflater)getBaseContext().getSystemService(LAYOUT_INFLATER_SERVICE);
LinearLayout myRoot = new LinearLayout(this);
View popupView = layoutInflater.inflate(R.layout.layout_result_popup, myRoot);
final PopupWindow popupWindow = new PopupWindow(popupView, ViewGroup.LayoutParams.WRAP_CONTENT, ViewGroup.LayoutParams.WRAP_CONTENT);
//what I want to show in the popup
TextView scorePopup = (TextView)findViewById(R.id.score_popup);
scorePopup.setText("Your score: " + score);
Button btnDismiss = (Button)popupView.findViewById(R.id.dismiss);
btnDismiss.setOnClickListener(new Button.OnClickListener(){
#Override
public void onClick(View v) {
// TODO Auto-generated method stub
popupWindow.dismiss();
}});
popupWindow.showAsDropDown(checkResultButton, 100, -1200);
popupWindow.setFocusable(true);
popupWindow.update();
}
When checkResult button is clicked, layout_result_popup is displayed.
I directly put a button at main activity and use onClick to show popup. So far, I managed to show the popup text in XML. But when I try to set some text to it, my app crashed.
Help please. :)

Try to replace those 2 lines with this:
runOnUiThread(new Runnable() {
#Override
public void run() {
TextView countView = (TextView)findViewById(R.id.count);
countView .setText("Count: " + count+ "/" + totalCount);
}
});
It very likely even works with the first line outside of the runOnUiThread

Android dialog title and divider color not changing

I have created custom Dialog.
I wants To change my Dialog title color and Divider line color.
I have gone through many answers but still M not successful.
I have tried different methods like:
int titleDividerId = resources.getIdentifier("titleDivider", "id", "android");
View titleDivider = dialog.getWindow().getDecorView().findViewById(titleDividerId);
titleDivider.setBackgroundColor(R.color.Red);
And used the following code:
final Dialog dialog = new Dialog(context);
dialog.setContentView(R.layout.alertdialog_caseadd);
dialog.setTitle("Add new court");
final Resources res = getResources();
final int titleDividerId = res.getIdentifier("titleDivider", "id", "android");
inal View titleDivider = dialog.findViewById(titleDividerId);
titleDivider.setBackgroundColor(res.getColor(android.R.color.holo_orange_dark));
dialog.getWindow().setBackgroundDrawableResource(R.drawable.alerttitle);
final EditText casetype= (EditText) dialog.findViewById(R.id.text);
Button dialogButton = (Button) dialog.findViewById(R.id.dialogButtonOK);
Button dialogButtoncancel = (Button) dialog.findViewById(R.id.dialogButtoncancel);
dialogButton.setOnClickListener(new OnClickListener() {
#Override
public void onClick(View v) {
// TODO Auto-generated method stub
if(casetype.getText().toString().equals(""))
Alert.showError("Error", "Please enter case type", CaseType.this);
else
if(Network.isOnline(getApplicationContext()))
new WebTask().execute();
else
Alert.showNetworkError(CaseType.this,inflater);
dialog.dismiss();
}
});
dialog.show();
dialogButtoncancel.setOnClickListener(new OnClickListener() {
#Override
public void onClick(View v) {
// TODO Auto-generated method stub
dialog.cancel();
}
});
That above code is not working, divider line and title color shows in blue color only.
Please help me change it.

final Dialog dialog = new Dialog(context);
dialog.setContentView(R.layout.alertdialog_caseadd);
//this method help me for title color change
dialog.setTitle(Html.fromHtml("<font color='#FFFFFF'>Add new case stage</font>"));
//this method help me for divider color change
int dividerId = dialog.getContext().getResources().getIdentifier("android:id/titleDivider", null, null);
View divider = dialog.findViewById(dividerId);
divider.setBackgroundColor(getResources().getColor(R.color.white));

Transparent AlertDialog Android

I want to make my AlertDialog transparent, the following is my code and the line where it should be transparent just doesnt work.
AlertDialog.Builder builder;
AlertDialog alertDialog;
context = getActivity();
LayoutInflater inflater = (LayoutInflater)context.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
View layout = inflater.inflate(R.layout.moreinfotable,null);
ListView list = (ListView) layout.findViewById(R.id.dialog_listView);
ArrayAdapter<String> adapter = new ArrayAdapter<String>(
ViewImage.this.getActivity(), R.layout.interior_listview,
R.id.interior_list_text, values);
list.setAdapter(adapter);
builder = new AlertDialog.Builder(context);
builder.setView(layout);
alertDialog = builder.create();
//THE LINE THAT DOESNT WORK// alertDialog.getWindow().setBackgroundDrawable(new ColorDrawable(Color.TRANSPARENT));
alertDialog.show();
can someone please help. Thank you.
This is what i want to do.

Use this way
alertDialog.show();
alertDialog.getWindow().setBackgroundDrawable(new ColorDrawable(android.graphics.Color.argb(0, 200, 200, 200)));
I did this on custom alert dialog.
Values are like alpha, red, green, blue. Range from 0 to 255. Change values of alpha to get different degree of transparency
I don't know if this will help you. This is how i created my dialog box (its a prompt to user to try the app without log-in)
public void promptUser()
{
final Dialog requestDialog= new Dialog(MyActivity.this);
requestDialog.requestWindowFeature(Window.FEATURE_NO_TITLE);
requestDialog.setContentView(R.layout.lyt_prompt_user);
TextView requestTitle = (TextView) requestDialog.findViewById(R.id.request_title);
TextView requestText = (TextView) requestDialog.findViewById(R.id.request_text);
Button acceptButton = (Button) requestDialog.findViewById(R.id.request_accept);
Button rejectButton = (Button) requestDialog.findViewById(R.id.request_reject);
requestTitle.setText("Don't want to login?");
requestText.setText("You can still explore the app with limited functionality.");
acceptButton.setOnClickListener(new OnClickListener() {
#Override
public void onClick(View v) {
// TODO Auto-generated method stub
// do something
requestDialog.dismiss();
finish();
startActivity(intent);
}
});
rejectButton.setOnClickListener(new OnClickListener() {
#Override
public void onClick(View v) {
// TODO Auto-generated method stub
requestDialog.dismiss();
(MyActivity.this).finish();
}
});
requestDialog.setCancelable(false);
requestDialog.show();
requestDialog.getWindow().setBackgroundDrawable(new ColorDrawable(android.graphics.Color.argb(0, 200, 200, 200)));
}
I tried changing the alpha from 0 to 90, it shows a faint white background, somewhat glassy feeling.
