Question

I’ve got a style set up for my Alert Dialog, and the style is being shown on [most] of the dialog without issue, the only problem are the buttons.

The phone is an HTC Evo running SenseUI, and the AlertDialog buttons continue to be skinned via the SenseUI theme. I have tried changing my application style (rtg_style) to be a child of Theme.Dialog instead of Theme.Light.NoTitleBar, and the buttons for the activities continue to be styled correctly, but the AlertDialogs also continue to be styled inccorrectly. I’m trying to avoid having to write a completely custom AlertDialog replacement, what else can I do?

styles.xml:

<style name="rtg_style" parent="@android:style/Theme.Light.NoTitleBar">
    <item name="android:windowBackground">@drawable/bluebg</item>
    <item name="android:buttonStyle">@style/rtg_Button</item>
    <item name="android:listViewStyle">@style/rtg_ListView</item>
    <item name="android:expandableListViewStyle">@style/rtg_ExpandableListView</item>
</style>

<style name="rtg_AlertDialog" parent="@style/rtg_style"> <!-- parent="@android:style/Theme.Dialog"> --> 
    <item name="android:buttonStyle">@style/rtg_Button</item>
    <item name="android:listViewStyle">@style/rtg_ListView</item>
    <item name="android:alertDialogStyle">@style/dialog</item>
</style>

<style name="rtg_Button" parent="@android:style/Widget.Button">
    <item name="android:background">@drawable/button</item>
    <item name="android:textColor">#ffffff</item>
    <item name="android:textSize">15sp</item>
    <item name="android:textStyle">bold</item>
    <item name="android:height">40dp</item>
</style>

<style name="rtg_ListView" parent="@android:style/Widget.ListView">
    <item name="android:listSelector">@drawable/listview</item>
</style>

<style name="rtg_ExpandableListView" parent="@android:style/Widget.ExpandableListView">
    <item name="android:listSelector">@drawable/listview</item>
</style>    

<style name="base">
    <item name="android:padding">10dp</item>
</style>    

<style name="title" parent="@style/base">
      <item name="android:textColor">#FFFFFF</item>
    <item name="android:textSize">16sp</item>
    <item name="android:textStyle">bold</item>
</style>

<style name="body" parent="@style/base">
    <item name="android:textColor">#000000</item>
    <item name="android:textStyle">normal</item>
</style>

<style name="dialog">
    <item name="android:fullDark">@drawable/dialog_body</item>
    <item name="android:topDark">@drawable/dialog_title</item>
    <item name="android:centerDark">@drawable/dialog_body</item>
    <item name="android:bottomDark">@drawable/dialog_footer</item>
    <item name="android:fullBright">@drawable/dialog_body</item>
    <item name="android:centerBright">@drawable/dialog_body</item>
    <item name="android:bottomBright">@drawable/dialog_footer</item>
    <item name="android:bottomMedium">@drawable/dialog_footer</item>
    <item name="android:centerMedium">@drawable/dialog_body</item>
    <item name="android:windowIsFloating">true</item>

</style>

Activity.java:

AlertDialog.Builder ab = new AlertDialog.Builder(new ContextThemeWrapper(OrderSummary.this, R.style.rtg_AlertDialog));
            ab.setTitle("Select a reason");
            String[] reasons = new String[Shared.Reasons_RejectAll.size()];
            for (int i = 0; i < Shared.Reasons_RejectAll.size(); i++) { 
                try {
                    reasons[i] = Shared.Reasons_RejectAll.get(i).Name;
                } catch (Exception ex) {
                    ex.printStackTrace();
                }
            }
            ab.setItems(reasons, new DialogInterface.OnClickListener() {
                @Override
                public void onClick(DialogInterface dialog, int which) {
                    rejectReason = Shared.Reasons_RejectAll.get(which).Name;
                    for (int i = 0; i <= r.ItemList.length; i++){
                        r.ItemList[index].item.get(i).setStatus(eItemStatus.REJECTED);
                        r.ItemList[index].item.get(i).setRejectReason(rejectReason);
                    }
                    adapter.notifyDataSetChanged();
                }
            }) 
            .setNegativeButton("Cancel", new DialogInterface.OnClickListener() {

                @Override
                public void onClick(DialogInterface dialog, int which) {
                    // No additional code required at this time.
                }
            });
            //ab.show();

            AlertDialog dialog = ab.create();
            dialog.show();

Found the answer! From what I’ve researched, the buttons on an alertdialog use their own layout that cannot be overridden, so I ended up subclassing Dialog and building a custom dialog myself.

CustomDialog.java:

public class CustomDialog extends Dialog implements OnClickListener {
TextView tvTitle;
TextView tvMessage;
Button btnOK;
ListView listView;
Context context;
ProgressBar prgWait;
ProgressBar prgBar;

public CustomDialog(Context context) {
    super(context, R.style.rtg_DialogActivity);
    setContentView(R.layout.dialog);
    this.context = context;

    // replace the background dim with a background blur effect
    WindowManager.LayoutParams lp = getWindow().getAttributes();
    lp.dimAmount = 0.0f;
    getWindow().setAttributes(lp);
    getWindow().addFlags(WindowManager.LayoutParams.FLAG_BLUR_BEHIND);

    tvTitle = (TextView) findViewById(R.id.tvDialogTitle);
    tvMessage = (TextView) findViewById(R.id.tvDialogMessage);
    btnOK = (Button) findViewById(R.id.btnDialog);
    listView = (ListView) findViewById(R.id.lvDialogList);
    prgWait = (ProgressBar) findViewById(R.id.prgDialog);
    prgBar = (ProgressBar) findViewById(R.id.prgDialogBar);
}

public CustomDialog setTitle(String text) {
    tvTitle.setText(text);      
    return this;
}

public CustomDialog setMessage(String text) {
    tvMessage.setVisibility(View.VISIBLE);
    tvMessage.setText(text);        
    return this;
}

public CustomDialog setList(List<String> list, OnItemClickListener l) {
    ArrayAdapter<String> aa = new ArrayAdapter<String>(this.getContext(), android.R.layout.simple_list_item_1, list);
    listView.setVisibility(View.VISIBLE);
    listView.setAdapter(aa);
    listView.setOnItemClickListener(l);         
    return this;
}

public CustomDialog setList(String[] list, OnItemClickListener l) {
    List<String> lString = new ArrayList<String>();
    for (String s : list)
        lString.add(s);     
    return setList(lString, l);
}

public CustomDialog setButton(String text, View.OnClickListener l) {
    btnOK.setText(text);
    btnOK.setOnClickListener(l);
    return this;
}

public CustomDialog setButton(String text) {
    return setButton(text, this);
}

public CustomDialog isIndeterminate(boolean b) {
    if (b) {
        prgWait.setVisibility(View.VISIBLE);
        btnOK.setVisibility(View.GONE);
    } else {
        prgWait.setVisibility(View.GONE);
        btnOK.setVisibility(View.VISIBLE);
    }
    return this;
}

public CustomDialog isProgress(boolean b) {
    if (b) {
        prgBar.setVisibility(View.VISIBLE);
        btnOK.setVisibility(View.GONE);
    } else {
        prgBar.setVisibility(View.GONE);
        btnOK.setVisibility(View.VISIBLE);
    }
    return this;
}

public CustomDialog setProgressMax(int max) {
    prgBar.setMax(max);
    return this;
}

public CustomDialog setProgress(int progress) {
    prgBar.setProgress(progress);
    return this;
}

public int getProgressMax() {
    return prgBar.getMax();
}

public int getProgress() {
    return prgBar.getProgress();
}

@Override
public void onClick(View v) {
    this.dismiss();
}

}
