    Supper = (TextView) findViewById(R.id.txtfourth3);


         Bundle bundle = this.getIntent().getExtras();
     String param1 = bundle.getString("Menuitem");

                 Toast.makeText(fourthscreen.this, param1, Toast.LENGTH_LONG).show();
     if(param1.equalsIgnoreCase("BreakFast"))

         Breakfast.setTypeface(null, Typeface.BOLD);
     }
     else 
         if(param1.equalsIgnoreCase("Lunch"))
         {
             Lunch.setTypeface(null, Typeface.BOLD);
         }
         else 
             if(param1.equalsIgnoreCase("Supper"))
             {
                 Lunch.setTypeface(null, Typeface.BOLD);
             }

Answer 1

yourTextView.setTypeface(null,Typeface.DEFAULT_BOLD);

尝试默认粗体，它适用于我

Answer 2

在xml中，只需在TextView标记

中编写以下行

android:textStyle="bold"

Answer 3

首先检查String param1 = bundle.getString("Menuitem"); p * aram1 *值，你只传递“BreakFast”，“Lunch”和“Supper”吗？

if(param1.equalsIgnoreCase("BreakFast"))
{
         Breakfast.setTypeface(null, Typeface.BOLD);
         Lunch.setTypeface(null, Typeface.NORMAL);
        Supper.setTypeface(null, Typeface.NORMAL);
}
else if(param1.equalsIgnoreCase("Lunch"))
{
         Lunch.setTypeface(null, Typeface.BOLD);
         Breakfast.setTypeface(null, Typeface.NORMAL);
        Supper.setTypeface(null, Typeface.NORMAL);
}
else if(param1.equalsIgnoreCase("Supper"))
{
        Supper.setTypeface(null, Typeface.BOLD);
        Lunch.setTypeface(null, Typeface.NORMAL);
        Breakfast.setTypeface(null, Typeface.NORMAL);
}

在我的代码textview中没有显示粗体我将做什么？
