Question

我从服务器获取数据并为该响应动态创建tablelayout，现在我需要每页只显示5行，我使用setvisible(view.invisible)隐藏所有表行，如何设置5行setvisible(view.visible)显示像分页一样的行？

我用于动态创建表的代码如下。

TableLayout tableLayout = (TableLayout) findViewById(R.id.tablenew);
         TableRow tableRow = new TableRow(this);
         tableRow.setId(1);
         tableRow.setBackgroundColor(Color.LTGRAY);
         tableRow.setPadding(0,0,1,1);
         tableRow.setLayoutParams(new TableLayout.LayoutParams());
         tableRow.setVisibility(View.INVISIBLE);
         TextView text = new TextView(this);
         text.setText(name);
         text.setBackgroundColor(Color.WHITE);
         text.setPadding(5, 5, 5, 5);
         text.setTextSize(30);
         text.setLayoutParams(new TableRow.LayoutParams());
         final Button button = new Button(this);
         button.setPadding(5, 5, 5, 5);
         button.setTextSize(30);
         button.setTag(value);
         button.setText("Install");
         button.setLayoutParams(new TableRow.LayoutParams());
         button.setOnClickListener(new View.OnClickListener() 
         {
               @Override
               public void onClick(View v) 
                {
                        TableLayout tableLayout = (TableLayout)        findViewById(R.id.tablenew);
                    final TableRow parent = (TableRow) v.getParent();
                    tableLayout.removeView(parent);
                          String id=(String) v.getTag();

                 }
          });//button click listener
         tableRow.addView(text);
         tableRow.addView(button);
         tableLayout.addView(tableRow);

试试这段代码：

tableraw.xml

<?xml version="1.0" encoding="utf-8"?>

<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent" >

<TableLayout
    android:id="@+id/tablenew"
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:layout_above="@+id/next"
    android:layout_alignParentTop="true" >
</TableLayout>

<Button
    android:id="@+id/next"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:layout_alignParentBottom="true"
    android:layout_centerHorizontal="true"
    android:text="next" />

</RelativeLayout>
