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):

Answer 1

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 2

I suspect that you are ending up showing white text on a white background! (Looking at the screenshot, the (i) icon is not showing up well either, suggesting that it was designed to be shown on a background other than white.

You can use the constructor public AlertDialog.Builder (Context context, int themeResId) to ensure you are using a specific theme to style your dialog, where the Theme_Material_Dialog is probably what you want.

Answer 3

new AlertDialog.Builder(context)
    .setTitle("Delete entry")
    .setMessage("Are you sure you want to delete this entry?")
    .setPositiveButton(android.R.string.yes, new DialogInterface.OnClickListener() {
        public void onClick(DialogInterface dialog, int which) { 
            // continue with delete
        }
     })
    .setNegativeButton(android.R.string.no, new DialogInterface.OnClickListener() {
        public void onClick(DialogInterface dialog, int which) { 
            // do nothing
        }
     })
    .setIcon(android.R.drawable.ic_dialog_alert)
     .show();

Hope this will help you.............

Answer 4

In my case all dialogs had the same color as fonts (title & message). What I have done to fix this state was the change of the color attribute in my theme. I copied the xml theme file into the 'res/values-v22' and set different color for marshmallow.

<resources>
    <style name="LywCompatTheme" parent="@style/Theme.AppCompat.Light.NoActionBar">
        <item name="android:textColorPrimary">@android:color/tertiary_text_dark</item>
    </style>
</resources>

or only for dialogs

<resources>
    <style name="LywCompatTheme" parent="@style/Theme.AppCompat.Light.NoActionBar">
        <item name="android:alertDialogTheme">@style/LywAlertDialogStyle</item>
    </style>
    <style name="LywAlertDialogStyle" parent="Base.Theme.AppCompat.Light.Dialog.Alert">
        <item name="android:textColorPrimary">@color/lyw_secondary_text_color</item>
    </style>
</resources>

Answer 5

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);
    }

Answer 6

Maybe your main text color is the same as dialog background color, in that case in your styles.xml use (just an example):

<style name="AlertDialog" parent="@android:style/Theme.Material.Light.Dialog.Alert">
    <item name="android:textColor">#000000</item>
</style>

and in dialog creation:

new AlertDialog.Builder(
        new ContextThemeWrapper(getContext(), R.style.AlertDialog))
).setMessage("test");
