TextView Txt1 = new TextView(this);
Txt1.setText("describe");
Txt1.setClickable(true);
Txt1.setContentDescription("this is description of text");
Txt1.setTextSize(TypedValue.COMPLEX_UNIT_DIP, 16);
Txt1.setTextColor(Color.rgb(187, 88, 15));
Txt1.setPadding(10, 10, 0, 0);
Txt1.setTypeface(Typeface.SERIF,Typeface.BOLD);
我尝试为文本视图设置内容描述,但如果我将光标放在文本上方,它不会显示描述。怎么做
