我想创建两个在第一行具有不同标题的表。两个表的标题行都有 4 列。如何创建两个具有不同 header 值的表，而无需两次编写相同的代码？

public void addHeaders(TableLayout t) { 
 
    /* Create a TableRow dynamically */ 
    TableRow tr = new TableRow(this); 
    tr.setBackgroundColor(GRAY); 
    tr.setLayoutParams(new TableLayout.LayoutParams( 
            TableLayout.LayoutParams.MATCH_PARENT, 
            TableLayout.LayoutParams.WRAP_CONTENT)); 
 
 
    /* Creating a TextView to add to the row */ 
    TextView addressTV = new TextView(this); 
    addressTV.setText("Address"); 
    addressTV.setTextColor(Color.BLACK); 
    addressTV.setTypeface(Typeface.DEFAULT, Typeface.BOLD); 
    addressTV.setGravity(Gravity.CENTER_HORIZONTAL); 
    addressTV.setPadding(0, 7, 0, 7); 
    addressTV.setLayoutParams(new TableRow.LayoutParams(0, LayoutParams.WRAP_CONTENT, 1.7f)); 
    tr.addView(addressTV);  // Adding textView to tablerow. 
 
    /* Creating a TextView to add to the row */ 
    TextView typeTV = new TextView(this); 
    typeTV.setText("Type"); 
    typeTV.setTextColor(Color.BLACK); 
    typeTV.setTypeface(Typeface.DEFAULT, Typeface.BOLD); 
    typeTV.setGravity(Gravity.CENTER_HORIZONTAL); 
    typeTV.setPadding(0, 7, 0, 7); 
    typeTV.setLayoutParams(new TableRow.LayoutParams(0, LayoutParams.WRAP_CONTENT, 1f)); 
    tr.addView(typeTV);  // Adding textView to tablerow. 
 
    /* Creating another textview */ 
    TextView amountTV = new TextView(this); 
    amountTV.setText("Amount"); 
    amountTV.setTextColor(Color.BLACK); 
    amountTV.setTypeface(Typeface.DEFAULT, Typeface.BOLD); 
    amountTV.setGravity(Gravity.CENTER_HORIZONTAL); 
    amountTV.setPadding(0, 7, 0, 7); 
    amountTV.setLayoutParams(new TableRow.LayoutParams(0, LayoutParams.WRAP_CONTENT, 1.2f)); 
    tr.addView(amountTV); // Adding textView to tablerow. 
 
    /* Creating another textview */ 
    TextView dateTV = new TextView(this); 
    dateTV.setText("Date"); 
    dateTV.setTextColor(Color.BLACK); 
    dateTV.setTypeface(Typeface.DEFAULT, Typeface.BOLD); 
    dateTV.setGravity(Gravity.CENTER_HORIZONTAL); 
    dateTV.setPadding(0, 7, 0, 7); 
    dateTV.setLayoutParams(new TableRow.LayoutParams(0, LayoutParams.WRAP_CONTENT, 1.5f)); 
    tr.addView(dateTV); // Adding textView to tablerow. 
 
    // Add the TableRow to the TableLayout 
    tl.addView(tr, new TableLayout.LayoutParams( 
            LayoutParams.MATCH_PARENT, 
            LayoutParams.WRAP_CONTENT)); 
 
} 

请您参考如下方法:

尝试将 header 名称作为输入传递。然后，您可以重用该代码来创建表格对象，同时动态调整标题文本字段。

例如这是一个简单的例子，假设总是 4 列...

public void callingFunction() { 
    TableLayout tl1 = // something; 
    TableLayout tl2 = // something else; 
 
    addHeaders(tl1, "Address", "Type", "Amount", "Date"); 
    addHeaders(tl2, "new", "strings", "for", "table"); 
} 
 
public TableRow addHeaders(TableLayout tl, String ... names) { 
 if (names.length != 4) throw new Exception("Unexpected number of table header names"); 
 
/* Create a TableRow dynamically */ 
TableRow tr = new TableRow(this); 
tr.setBackgroundColor(GRAY); 
tr.setLayoutParams(new TableLayout.LayoutParams( 
        TableLayout.LayoutParams.MATCH_PARENT, 
        TableLayout.LayoutParams.WRAP_CONTENT)); 
 
 
/* Creating a TextView to add to the row */ 
TextView addressTV = new TextView(this); 
addressTV.setText(names[0]); 
addressTV.setTextColor(Color.BLACK); 
addressTV.setTypeface(Typeface.DEFAULT, Typeface.BOLD); 
addressTV.setGravity(Gravity.CENTER_HORIZONTAL); 
addressTV.setPadding(0, 7, 0, 7); 
addressTV.setLayoutParams(new TableRow.LayoutParams(0, LayoutParams.WRAP_CONTENT, 1.7f)); 
tr.addView(addressTV);  // Adding textView to tablerow. 
 
/* Creating a TextView to add to the row */ 
TextView typeTV = new TextView(this); 
typeTV.setText(names[1]); 
typeTV.setTextColor(Color.BLACK); 
typeTV.setTypeface(Typeface.DEFAULT, Typeface.BOLD); 
typeTV.setGravity(Gravity.CENTER_HORIZONTAL); 
typeTV.setPadding(0, 7, 0, 7); 
typeTV.setLayoutParams(new TableRow.LayoutParams(0, LayoutParams.WRAP_CONTENT, 1f)); 
tr.addView(typeTV);  // Adding textView to tablerow. 
 
/* Creating another textview */ 
TextView amountTV = new TextView(this); 
amountTV.setText(names[2]); 
amountTV.setTextColor(Color.BLACK); 
amountTV.setTypeface(Typeface.DEFAULT, Typeface.BOLD); 
amountTV.setGravity(Gravity.CENTER_HORIZONTAL); 
amountTV.setPadding(0, 7, 0, 7); 
amountTV.setLayoutParams(new TableRow.LayoutParams(0, LayoutParams.WRAP_CONTENT, 1.2f)); 
tr.addView(amountTV); // Adding textView to tablerow. 
 
/* Creating another textview */ 
TextView dateTV = new TextView(this); 
dateTV.setText(names[3]); 
dateTV.setTextColor(Color.BLACK); 
dateTV.setTypeface(Typeface.DEFAULT, Typeface.BOLD); 
dateTV.setGravity(Gravity.CENTER_HORIZONTAL); 
dateTV.setPadding(0, 7, 0, 7); 
dateTV.setLayoutParams(new TableRow.LayoutParams(0, LayoutParams.WRAP_CONTENT, 1.5f)); 
tr.addView(dateTV); // Adding textView to tablerow. 
 
// Add the TableRow to the TableLayout 
tl.addView(tr, new TableLayout.LayoutParams( 
        LayoutParams.MATCH_PARENT, 
        LayoutParams.WRAP_CONTENT)); 
}
