Android 6.0 Dialog text doesn't appear

Question

I updated my phone to Android 6.0 and I have these 2 problems with dialogs:

1)The title is shown but the messages isn't for alert dialog(SOLVED):

        new AlertDialog.Builder(context).setTitle("Title").setMessage("Message");

2)Also custom dialog fragment's title is not shown(NOT SOLVED):

        getDialog().setTitle("Title");

There was not such a problem in lollipop or in older versions, the problem appeared only after updating my phone to marshmallow.

How to solve the problem?

Solution 1

Use constructor with theme for Lollipop and newer android versions:

Dark theme

    AlertDialog.Builder builder;
    if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.LOLLIPOP) {
        builder = new AlertDialog.Builder(context, android.R.style.Theme_Material_Dialog_Alert);
    } else {
        builder = new AlertDialog.Builder(context);
    }

And for Light theme

    AlertDialog.Builder builder;
    if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.LOLLIPOP) {
        builder = new AlertDialog.Builder(context, android.R.style.Theme_Material_Light_Dialog_Alert);
    } else {
        builder = new AlertDialog.Builder(context);
    }

I've come across a few answers that say that you should use the following in your app theme:

<item name="android:alertDialogTheme">@style/Theme.AppCompat.Light.Dialog.Alert</item>

While that is correct, it wasn't working in all places for me. Eventually, I realized that in some places I was using the regular AlertDialog builder and in other places I was using the support builder. If you are using the support AlertDialog, make sure to also include the following in your theme:

<item name="alertDialogTheme">@style/Theme.AppCompat.Light.Dialog.Alert</item>

Just put this in your styles file inside your Base Theme style tag and you are good to go

<item name="android:alertDialogTheme">@style/Theme.AppCompat.Light.Dialog.Alert</item>

Answer for 2), we need to call setStyle() before onCreateDialog() because theme is used in onCreateDialog()

@NonNull
@Override
public Dialog onCreateDialog(Bundle savedInstanceState) {
    if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.LOLLIPOP) {
        setStyle(STYLE_NORMAL, android.R.style.Theme_Material_Light_Dialog_Alert);
    }
    Dialog dialog = super.onCreateDialog(savedInstanceState);
    dialog.setTitle(R.string.dialog_title);
    return dialog;
}

i tried to fix this problem by making a style of my own.

your dialog object should be like this and your style pointed to this Dialog will be written below

new AlertDialog.Builder(new ContextThemeWrapper(Context, R.style.Dialog))
            .setTitle("Title")
            .setMessage("Sample Message ...").show();

R.style.Dialog ::

<style name="Dialog">
    <item name="android:textColorPrimary">@color/primary_text</item>
    <item name="android:textColor">@color/primary_color</item>
</style>

Colors ::

<color name="primary_text">#212121</color>
<color name="primary_color">#2196f3</color>

finally the output should be something like this

Note : "android:textColorPrimary" goes for dialog setMessage and "android:textColor" goes for dialog setTitle ; i do not use setPositive and setNegative button and listener in my dialog object but you can see them in the picture if you want you can make your own dialog object.
