是否有可能减少 AlertDialog.Builder 标题字体的大小和积极的按钮的大小？如果是的话，让我怎么办？

Is it possible to reduce the AlertDialog.Builder title font size and positive button size? If yes, Just let me how to do?

推荐答案

关于字体大小，你可以使用这个：

About font size you can use this:

SpannableStringBuilder ssBuilser = new SpannableStringBuilder("Sample");
StyleSpan span = new StyleSpan(Typeface.ITALIC);
ScaleXSpan span1 = new ScaleXSpan(1);
ssBuilser.setSpan(span, 0, 5, Spanned.SPAN_INCLUSIVE_INCLUSIVE);
ssBuilser.setSpan(span1, 0, 5, Spanned.SPAN_INCLUSIVE_INCLUSIVE);

AlertDialog.Builder builder = new AlertDialog.Builder(MainActivity.this);

builder.setTitle(ssBuilser);

builder.show();

你也可以设置自定义的标题：

Also You can set custom title:

float size = 25;    

AlertDialog.Builder builder = new AlertDialog.Builder(this);    
final TextView myView = new TextView(getApplicationContext());
myView.setText("A Sample Title to Change Dialog Title");
myView.setTextSize(size);
builder.setCustomTitle(myView);
