AlertDialog样式

我们有一个项目,将运行在不同的屏幕大小的AlertDialog v7 AppComp有一个风格。

• 我的问题是如何设置AlertDialog消息文本大小的样式?

我已经编写了一个CustomDialog,作为一个带有自己xml文件的活动,它似乎工作得很好,只是emulator在运行时显示了一个类似幽灵的xml文件视图!我最近看到一篇帖子,暗示消息的文本大小无法更改。我有一些关于如何使用DisplayMetrics的知识,但我宁愿不使用这个约定。

以下是AletDialog和样式的设计代码。如果有人能向我保证幽灵图像不会出现在真正的设备上,我可能会放弃并使用这种方法,这似乎很笨拙

    private void doWhat() {
    // R.style.MyAlertDialogStyle see res/values/styles
    AlertDialog.Builder alertDialog = new AlertDialog.Builder(this, R.style.MyAlertDialogStyle);

    // Setting Dialog Title
    alertDialog.setTitle("Confirm Reset of Password");

    // Setting Dialog Message
    alertDialog.setMessage("Click YES to create a new master password");

    // Setting Icon to Dialog
    alertDialog.setIcon(R.drawable.caution);

    // Setting Positive "Yes" Button
    alertDialog.setPositiveButton("YES", new DialogInterface.OnClickListener() {

        public void onClick(DialogInterface dialog, int which) {
            // Write your code here to invoke YES event
            db = helper.getReadableDatabase();

            String q = "SELECT * FROM masterPW";
            Cursor cursor = db.rawQuery(q,null);
            // Above query gets TABLE_PW data from Col_IDI
            // TABLE_PW will only ever have one row of data

            int rowID = 99;
            if(cursor.moveToFirst()){
                rowID = cursor.getInt(cursor.getColumnIndex(Col_IDI));
                str = cursor.getString(cursor.getColumnIndex(Col_MPW));
            }
            cursor.close();

            // Line of code below WORKS deletes entire TABLE <=====
            // Not a recomended way to re-set the master password
            // db.delete(TABLE_PW, null, null);

            String num = Integer.toString(rowID);

            db.delete(TABLE_PW, Col_IDI + " = ?", new String[] { num });
            db.close();

            Intent intentYY = new Intent(DetailsActivity.this, MainActivity.class );
            startActivity( intentYY );
        }
    });

    // Setting Negative "NO" Button
    alertDialog.setNegativeButton("NO", new DialogInterface.OnClickListener() {
        public void onClick(DialogInterface dialog, int which) {
            // Write your code here to invoke NO event
            Toast.makeText(getApplicationContext(), "Password NOT Changed", Toast.LENGTH_SHORT).show();
            dialog.cancel();
        }
    });
    // Showing Alert Message and set the SIZE of the alertDialog
    alertDialog.show().getWindow().setLayout(1300, 500);// was 1100 500

}
