问题描述

我在 Android 中创建应用程序时遇到一个问题.在我的应用程序中，我将 ArrayList 数据绑定到 TableLayout.当我运行应用程序时，只绑定了最后一列数据.我要求绑定所有列.请帮帮我...

I have one problem to create my application in Android. Here in my application I bind the ArrayList Data into TableLayout. When I run the application, only the last column of data is bound. I have required all columns to be bound. Please help me...

我提供了我的代码:

查看Task.xml:

View Task.xml:

<TableLayout
                android:id="@+id/score_table1"
                android:layout_width="fill_parent"
                android:layout_height="wrap_content">
                <TableRow></TableRow>
 </TableLayout>

查看task.java:

View task.java:

TableLayout table = (TableLayout) findViewById(R.id.score_table1);

            for(int i=0;i<object.size();i++)
            {


                    TableRow row=new TableRow(ViewTask.this);

                    @SuppressWarnings("unchecked")
                    ArrayList<String> data1 = (ArrayList<String>) object.get(i);

                    TextView taskdate = new  TextView(ViewTask.this);
                    taskdate.setTextSize(10);
                    taskdate.setText(data1.get(0).toString());
                    row.addView(taskdate);

                    TextView title = new  TextView(ViewTask.this);
                    taskdate.setText(data1.get(1).toString());
                    row.addView(title);
                    taskdate.setTextSize(10);


                    TextView taskhour = new  TextView(ViewTask.this);
                    taskdate.setText(data1.get(2).toString());
                    taskhour.setTextSize(10);
                    row.addView(taskhour);


                    TextView description = new  TextView(ViewTask.this);
                    taskdate.setText(data1.get(3).toString());
                    row.addView(description);
                    description.setTextSize(10);

                    table.addView(row);

            }               

推荐答案

您正在 for 循环中创建多个 textView 但仅将文本设置为第一个 textTiew.

You're creating multiple textView in the for loop but setting text only to the first textTiew.

TextView taskdate = new  TextView(ViewTask.this);
taskdate.setTextSize(10);
taskdate.setText(data1.get(0).toString());
row.addView(taskdate);

TextView title = new  TextView(ViewTask.this);
taskdate.setText(data1.get(1).toString());
row.addView(title);
taskdate.setTextSize(10);

TextView taskhour = new  TextView(ViewTask.this);
taskdate.setText(data1.get(2).toString());
taskhour.setTextSize(10);
row.addView(taskhour);

TextView description = new  TextView(ViewTask.this);
taskdate.setText(data1.get(3).toString());
row.addView(description);
description.setTextSize(10);

注意，使用 taskdate 变量，您正在多次设置文本.

Observe that with the taskdate variable, you are setting text multiple times.
