Android 将字体设置为alertdialog

我有一个alertdialog，我使用字体作为标题、消息和alertdialog的按钮。 问题是，标题和消息视图使用的是字体，而不是按钮？ 为什么？ 这是我的密码

public boolean functionInQuestion(MissingParameters ... parameters) {
    Typeface myTypeFace = Typeface.createFromAsset(getAssets(),"fonts/hhh.ttf");
    TextView mysite = new TextView(mainn.this);
    TextView fbpage = new TextView(mainn.this);
    TextView content5 = new TextView(mainn.this);
    TextView Mytitle5 = new TextView(mainn.this);

    mysite.setText("google");
    fbpage.setText("fb");
    Mytitle5.setText("google and facebook");
    content5.setText("linka to google and facebook");

    mysite.setTypeface(myTypeFace);
    fbpage.setTypeface(myTypeFace);
    content5.setTypeface(myTypeFace);
    Mytitle5.setTypeface(myTypeFace);

    AlertDialog.Builder builder = new AlertDialog.Builder(mainn.this);
    builder.setView(content5);
    builder.setCustomTitle(Mytitle5);
    builder.setIcon(R.drawable.about);

    builder.setPositiveButton(fbpage.getText(), new DialogInterface.OnClickListener() {  
        @Override  
        public void onClick(DialogInterface dialog, int which) { 
            // When LeftButton click, source implementing is put here.  
            String url = "http://www.facebook.com";
            Intent i = new Intent(Intent.ACTION_VIEW);
            i.setData(Uri.parse(url));
            startActivity(i);
        }
    });

    builder.setNeutralButton(mysite.getText(), new DialogInterface.OnClickListener() { 
        @Override
        public void onClick(DialogInterface dialog, int which) {  
            // When CenterButton click, source implementing is put here.
            String url = "http://www.google.com";
            Intent i = new Intent(Intent.ACTION_VIEW);
            i.setData(Uri.parse(url));
            startActivity(i);
        }
    });

    builder.show();
    return false;
}

试试这个，它一定有用：）

对不起，我说不工作。。。但这是一个书写错误。。。。如果您使用的是否定按钮use

button button\u negative=（button）dialog.findViewById（android.R.id.button2），则它不起作用
