如何在 Android 代码中动态加粗和下划线？

Question

如何将分行名称：、分行编号：、分行电话号码：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。这四个只是它们的标题。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) ;

Answer 1

是的，您可以使用 HTML 标记来装饰 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。像这样的：

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。

Answer 2

使用 HTML 内容来格式化您的文本，例如：

branchInfoString = branchInfoString + 

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

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

dbDataView.setText(Html.fromHtml(branchInfoString ));

Answer 3

你可以格式化你的字符串并在 textview 中设置它

String some_string = Html.fromHtml(YourHTMLFromattedString)
dbDataView.setText(some_string);

Answer 4

使用Html.fromHtml(String source) 和HTML <b></b> 和<i></i> 标签以粗体和斜体显示一些文本

for(BranchInfo aBranch : dbDataList ){

branchInfoString = branchInfoString + 

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

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

}

//your code ...

dbDataView.setText(Html.fromHtml(branchInfoString)) ;

您必须创建一个包含多行的 tableView，这些行将在运行时添加。第一行将包含列标题。

例如

<TableLayout android:id="@+id/class">
    <TableRow android:id="@+id/headers">
        <TextView android:id="@+id/branch_name"
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:typeface="serif">
        <TextView android:id="@+id/branch_no"
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:typeface="serif">
        <TextView android:id="@+id/branch_phone_no"
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:typeface="serif">
        <TextView android:id="@+id/branch_timings"
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:typeface="serif">
    </TableRow>
</TableLayout>

要将数据添加到该表中，请在类中添加如下内容：

TableLayout layout =     (TableLayout)LayoutInflater.from(canvas.getContext()).inflate(R.layout.class, null);

TableRow headerRow = (TableRow) layout.findViewById(R.id.header);
TextView branchName = (TextView) layout.findViewById(R.id.branch_name);
TextView branchNo = (TextView) layout.findViewById(R.id.branch_no);
TextView branchPhoneNo = (TextView) layout.findViewById(R.id.branch_phone_no);
TextView branchTimings = (TextView) layout.findViewById(R.id.branch_timings);

branchName.setText("Branch Name");
branchName.setTypeFace(null, Typeface.BOLD);

branchNo.setText("Branch No");
branchNo.setTypeFace(null, Typeface.BOLD);

branchPhoneNo.setText("Branch Phone No");
branchPhoneNo.setTypeFace(null, Typeface.BOLD);

branchTimings.setText("Branch Timimgs");
branchTimings.setTypeFace(null, Typeface.BOLD);


for (int i=0; i<noOfRows; i++) {
    TableRow dataset = new TableRow(context);
    TextView branchName = new TextView(context);
    TextView branchNo = new TextView(context);
    TextView branchPhoneNo = new TextView(context);
    TextView branchTimings = new TextView(context);

    branchName.setText("SampleBranchName" + i);
    branchNo.setText("SampleNumber" + i);
    branchPhoneNo.setText("SamplePhoneNumber" + i);
    branchTimings.setText("SampleTimings" + i);

    dataset.addView(branchName);
    dataset.addView(branchNo);
    dataset.addView(branchPhoneNo);
    dataset.addView(branchTimings);

    layout.addView(dataset);
}
