java - 如何在 Android 代码中动态地为字符串添加粗体和下划线？

Question

如何使分行名称:、分行编号:、分行电话:和分行时间设置为粗体和斜体: 在 Java 代码中？数据库数据应保持简单格式。这四个只是其中的标题。在这种(当前)情况下，它以简单格式打印/显示整个数据，用户在读取这些数据时遇到问题。

String branchInfoString = "" ;

// fetching all the database data in a list
List<BranchInfo> dbDataList = _dbHandler.getAllInfo() ;

// getting that data into a string that will be displayed in TextView
for(BranchInfo aBranch : dbDataList ){

branchInfoString = branchInfoString + 

          "Branch Name: " + aBranch.getBranchName() + "\n" +
          "Branch No: " + aBranch.getBranchNo() + "\n" + 
          "Branch Phone No: " + aBranch.getBranchPhone() + "\n" + 
          "Branch Timings: " + aBranch.getBranchTiming() + "\n" + 

          "\n --------------------------------------- \n \n" ;  

}

// showing all the branch data in a text_view
setContentView(R.layout.db_branch_list) ;
TextView dbDataView = (TextView)findViewById(R.id.db_branch_list) ;
dbDataView.setText(branchInfoString) ;

是的，您可以使用 HTML 标记装饰 TextView 中的文本。这不仅包括斜体和粗体，还包括字体颜色和其他一些东西。像这样:

branchInfoHtmlString = branchInfoString + 

      "<b>Branch Name: " + aBranch.getBranchName() + "</b>\n" +
      "<i>Branch No: " + aBranch.getBranchNo() + "</i>\n" + 
      "<font >Branch Phone No: " + aBranch.getBranchPhone() + "</font>\n" + 
      "<font color="#FFDDDDDD">Branch Timings: " + aBranch.getBranchTiming() + "</font>\n" + 

      "\n --------------------------------------- \n \n" ;  

}

// showing all the branch data in a text_view
setContentView(R.layout.db_branch_list) ;
TextView dbDataView = (TextView)findViewById(R.id.db_branch_list) ;
dbDataView.setText(Html.fromHtml(branchInfoHtmlString)) ;

并非所有 HTML 标签都受支持，您可以找到标签列表 here和 here .
