向表格布局中的行添加数据

Question

我正在尝试创建一种 EPG 类型的布局，我提到了这个 (Print out ArrayList content in Android TableLayout) 我的问题是当我尝试添加行时，它们被添加为新行，但我需要将这些值添加到现有行中。 这是我的 XML 文件：

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="wrap_content"
    android:layout_height="match_parent"
    android:orientation="vertical" >



    <TableLayout
        android:id="@+id/myTableLayout"
        android:layout_width="match_parent"
        android:layout_height="354dp"
        android:background="#6495ED"
        android:stretchColumns="*" >


     <TableRow
            android:id="@+id/tablerow1"
            android:layout_width="match_parent"
            android:layout_height="wrap_content" >

             <TextView
                 android:id="@+id/textView1"
                 android:layout_width="wrap_content"
                 android:layout_height="wrap_content"

                 android:text="Some Text " 
                />

             <TextView
             android:id="@+id/textView2"
             android:layout_width="wrap_content"
             android:layout_height="wrap_content"

             android:text="Some Text"
              />

             <TextView
             android:id="@+id/textView3"
             android:layout_width="wrap_content"
             android:layout_height="wrap_content"

             android:text="Some Text" />



        </TableRow>
</TableLayout>

我的 java 文件是

TableLayout table = (TableLayout) findViewById(R.id.myTableLayout);
            for(int i=0;i<channel_arraylist.size();i++)
            {

                TableRow tableRow2=new TableRow(VideoDatabase1.this);
                localchannel1= channel_arraylist.get(i);

                  TextView tvid=new TextView(VideoDatabase1.this);
                  tvid.setText(""+Integer.toString(localchannel1.getID()));
             tableRow2.addView(tvid);

            table.addView(tableRow2);

Answer 1

我对你的问题的回答。

    private ArrayList<String> data = new ArrayList<String>();
    private ArrayList<String> data1 = new ArrayList<String>();
    private TableLayout table;    

    data.add("Samsung");
    data.add("Apple");
    data.add("Pixle");
    data.add("Vivo");
    data1.add(" $109");
    data1.add(" $200");
    data1.add(" $399");
    data1.add(" $290");        


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

    for(int i=0;i<data.size();i++)
    {
        TableRow row=new TableRow(this);
        String phone = data.get(i);
        String amount = data1.get(i);
        TextView tv1=new TextView(this);
        tv1.setText(phone);
        TextView tv2=new TextView(this);
        tv2.setText(amount);
        row.addView(tv1);
        row.addView(tv2);
        table.addView(row);
    }

Answer 2

尝试替换

TableRow tableRow2=new TableRow(VideoDatabase1.this);

到

TableRow tableRow2=((TableRow)table.getChildAt(0));

另外，在行中设置断点：

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

在调试模式中观察你的“表”变量。它必须包含至少 1 个孩子。一定有帮助。

关于您的问题：必须在下面添加 TableRow，因为您向 tableLayout 添加了一个新行。而且正常。

Answer 3

我终于找到了解决办法。要将视图添加到特定表中，只需执行

TextView tvid=(TextView)findViewById(R.id.textView1); 
          tvid.setText(localchannel1.getName()); 

这里的id 指的是您在布局文件中声明的id。简单地说，这会将值插入相应的列中。谢谢你的一切。
