我的代码如下

    //--------------------------------------------------------------------------------------------------
    // Creating Table Header
    //--------------------------------------------------------------------------------------------------

    TableRow followup_tr_head = new TableRow(this);
    followup_tr_head.setId(10);
    followup_tr_head.setBackgroundResource(R.drawable.list_header);
    followup_tr_head.setLayoutParams(new LayoutParams(
            LayoutParams.FILL_PARENT,
            LayoutParams.WRAP_CONTENT));


    final TextView time_name_title = new TextView(this);
    time_name_title.setId(20);
    time_name_title.setText("Time");
    time_name_title.setTextColor(Color.WHITE);
    time_name_title.setPadding(5,5,5,5);
    followup_tr_head.addView(time_name_title);// add the column to the table row here
    time_name_title.setTextSize(12);    

    final TextView student_name_title = new TextView(this);
    student_name_title.setId(20);
    student_name_title.setText("Student Name");
    student_name_title.setTextColor(Color.WHITE);
    student_name_title.setPadding(5,5,5,5);
    followup_tr_head.addView(student_name_title);// add the column to the table row here
    student_name_title.setTextSize(12);

Answer 1

ActionBar在API 11中提供。您不能在较低的API级别中使用它。

Answer 2

是的，您不能在API级别11下使用ActionBar。要在较低的api级别使用操作栏，请使用ActionBarSherlock

Answer 3

我导入了导入android.app.ActionBar.LayoutParams;

我应该导入android.widget.TableRow.LayoutParams;

表视图给出错误低于API级别11
