I have a popup for downloading the audio instruction in my app. What I am trying to do is I want to change the default text color of “OK” to blue. I tried something but its not working. Here is my code:
private void showDownloadPgmPopup() {
android.app.AlertDialog.Builder builder = new android.app.AlertDialog.Builder(getActivity());
builder.setTitle("Download instructional audio?");
builder.setMessage(ParamConstants.AUDIODOWNLOADPERMISSION);
builder.setNegativeButton("No", new DialogInterface.OnClickListener() {
@Override
public void onClick(DialogInterface dialog, int which) {
WwDatabaseHelper.storeSelectedWeekAndDay(getActivity(), mSelectedWeekDataModel);
goToMoveScreen();
}
});
builder.setPositiveButton("OK", new DialogInterface.OnClickListener() {
@Override
public void onClick(DialogInterface dialog, int which) {
AndroidDownloadFileByProgressBarActivity.StartAudioAssetDownload(getActivity());
}
}).create();
// change the text color of download instruction ok button
final android.app.AlertDialog dialog = builder.show();
dialog.setOnShowListener( new DialogInterface.OnShowListener() {
@Override
public void onShow(DialogInterface arg0) {
dialog.getButton(AlertDialog.BUTTON_POSITIVE).setTextColor(Color.parseColor("#ff5722"));
}
});
dialog.setCanceledOnTouchOutside(false);
dialog.show();
}
But the change is not reflecting can anyone tell me what i am doing wrong?
You have to provide a custom style id in the AlertDialog constructor:
AlertDialog.Builder(Context context, int themeResId)
and the style file should be something like:
<style name="AlertDialogCustom" parent="Theme.AppCompat.Light.Dialog.Alert">
<item name="android:colorAccent">#0000FF</item>
</style>
Answer：
Change your method to
private void showDownloadPgmPopup() {
android.app.AlertDialog.Builder builder = new android.app.AlertDialog.Builder(getActivity(),R.style.AlertDialog);
...
..
.
}
And under res/values/styles.xml add a new AlertDialog style
<style name="AlertDialog" parent="Base.Theme.AppCompat.Light.Dialog">
<item name="android:textColor">#000000</item>
<item name="android:textColorPrimary">#595959</item>
<item name="android:colorAccent">#1b5e20</item>
</style>
Below is the screen shot of these changes
Answer：
You have two ways to do this
- Override default dialog.
//1. create a dialog object 'dialog'
MyCustomDialog builder = new MyCustomDialog(getActivity(), "Exit", errorMessage);
AlertDialog dialog = builder.setNegativeButton("OK", new DialogInterface.OnClickListener() {
@Override
public void onClick(DialogInterface dialogInterface, int i) {
...
}
}).create();
//2. now setup to change color of the button
dialog.setOnShowListener( new OnShowListener() {
@Override
public void onShow(DialogInterface arg0) {
dialog.getButton(AlertDialog.BUTTON_NEGATIVE).setTextColor(Color.parseColor("#f34235"));
}
}
dialog.show()
- Create your own
customdialog
// create instance of dialog
AlertDialog.Builder dialogBuilder = new AlertDialog.Builder(this);
// get inflater and inflate layour for dialogue
LayoutInflater inflater = this.getLayoutInflater();
View dialogView = inflater.inflate(R.layout.alert_label_editor, null);
// now set layout to dialog
dialogBuilder.setView(dialogView);
// create instance like this OR directly mentioned in layout
Button button= (Button) dialogView.findViewById(R.id.label_field);
button.setText("test label");
AlertDialog alertDialog = dialogBuilder.create();
// show dialog
alertDialog.show();
Answer：
Try calling the setTextColor after show. Refer below:
show()
dialog.getButton(AlertDialog.BUTTON_NEGATIVE).setTextColor(Color.YELLOW)
Answer：
I could manage to change the text color to Red by using SpannableString in place of normal string.
Example –
var okString = new SpannableString("OK");
okString.SetSpan(new ForegroundColorSpan(Color.Red), 0, Strings.Report.Length, 0);
I then passed the variable okString to setItems().
Try passing spannableString to setPositiveButton().
Answer：
dialog.getButton(AlertDialog.BUTTON_NEGATIVE).setTextColor(Color.YELLOW)
The above code didn’t work for me, but the below one did work:
dialog.getButton(DialogInterface.BUTTON_NEGATIVE).setTextColor(getResources().getColor(R.color.Yellow));
Answer：
Simply, you just change your “OK” text with this code:
Html.fromHtml("<font color='#0000FF'>OK</font>")
This code will totally change your text color depend on your added color value while #0000FF is blue.
