表格代码
public class Main5Activity extends AppCompatActivity {
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main5);
{
TableLayout markstable = (TableLayout) findViewById(R.id.datatable);
TableRow tableRow = new TableRow(this);
TextView tv0 = new TextView(this);
tv0.setText(" Student ");
tv0.setTextColor(Color.WHITE);
tableRow.addView(tv0);
TextView tv1 = new TextView(this);
tv1.setText(" Oral Mark ");
tv1.setTextColor(Color.WHITE);
tableRow.addView(tv1);
TextView tv2 = new TextView(this);
tv2.setText(" Home Work ");
tv2.setTextColor(Color.WHITE);
tableRow.addView(tv2);
TextView tv3 = new TextView(this);
tv3.setText(" Test ");
tv3.setTextColor(Color.WHITE);
tableRow.addView(tv3);
markstable.addView(tableRow);
for (int i = 0; i < 50; i++) {
TableRow tableRow1 = new TableRow(this);
TextView t1v = new TextView(this);
t1v.setText( + i);
t1v.setTextColor(Color.WHITE);
t1v.setGravity(Gravity.CENTER);
tableRow1.addView(t1v);
TextView t2v = new TextView(this);
t2v.setText("Student " + i);
t2v.setTextColor(Color.WHITE);
t2v.setGravity(Gravity.CENTER);
tableRow1.addView(t2v);
TextView t3v = new TextView(this);
t3v.setText("Student" + i);
t3v.setTextColor(Color.WHITE);
t3v.setGravity(Gravity.CENTER);
tableRow1.addView(t3v);
TextView t4v = new TextView(this);
t4v.setText( + i * 15 / 32 * 10);
t4v.setTextColor(Color.WHITE);
t4v.setGravity(Gravity.CENTER);
tableRow1.addView(t4v);
markstable.addView(tableRow1);
}
}
}
}
在这里，我尝试为老师制作一个表格，以将学生姓名和分数保存在其中并保存以对其进行编辑、删除或替换 桌子就崩溃了， 顺便说一句，我试图让它们成为输入数据的文本字段，但它也会崩溃 这是我的错误：
