如何减少Android布局中文本之间的行间距？

<TextView
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:text="Hello World!"
    android:lineSpacingExtra="-4dp" />

<TextView
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:text="Hello World!"
    android:lineSpacingMultiplier="0.8" />

TextView textView = findViewById(R.id.textView);
String text = "Hello World!";
SpannableString spannableString = new SpannableString(text);
spannableString.setSpan(new LeadingMarginSpan.Standard(0, -4), 0, text.length(), Spanned.SPAN_INCLUSIVE_EXCLUSIVE);
textView.setText(spannableString);
