Question

我想在ui中显示表，数据来自sqllite数据库表。我怎样才能在Android中实现？通过以下我创建具有静态内容的表：

<?xml version="1.0" encoding="utf-8"?>  
<TableLayout  
    xmlns:android="http://schemas.android.com/apk/res/android"  
    android:id="@+id/tableLayout1"

    android:layout_height="match_parent"  
    android:shrinkColumns="*"  
    android:stretchColumns="*">

请参阅一次如何将动态值附加到Android中的行和Android前端应用中的显示表中。

你必须在xml，

中创建一个类似下面的表

<TableLayout
android:id="@+id/rows_table"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:layout_marginBottom="10dip"
android:layout_marginTop="10dip"
android:padding="10dp"
android:background="color or drawable"
android:shrinkColumns="*"  
android:stretchColumns="*"/>

并在代码中声明表格，

RowsTable = (TableLayout) findViewById(R.id.rows_table);

您可以在AsyncTask PostExcute或您希望的地方执行以下操作，

// entries are the no.of that you decided to print dynamically.
    int rows;
                    for (rows=0;rows<entries.length();rows++)
                {

                    TableRow trTwo = new TableRow(Activity.this);
                    trTwo.setLayoutParams(new LayoutParams(LayoutParams.MATCH_PARENT,
                            LayoutParams.FILL_PARENT));
// Here you can get the cursor data , which is going to be displayed in the coloumns.
//entriesVar is the coloumn data.
                    for(int coloumn = 2; coloumn < entriesVar.length; coloumn++)
                    {
                    //Your database values
                    if (coloumn == 1)
                    {

                        //Any Header options, If you wish to show any table headers

                    }


                    String questionable = "sometext";
                TextView txtTwo = new TextView(ReportsActivity.this);

                txtTwo.setText(questionable);
                txtTwo.setLayoutParams(new LayoutParams(
            LayoutParams.FILL_PARENT, LayoutParams.FILL_PARENT));
            txtTwo.setTextColor(Color.BLACK);
            txtTwo.setGravity(Gravity.CENTER);
            txtTwo.setBackgroundResource(R.drawable.table_border_new);
            txtTwo.setPadding(3, 3, 3, 3);
            trTwo.addView(txtTwo);// Binding Text To Row
            }
           // Adding View To Table
           RowsTable.addView(trTwo, new TableLayout.LayoutParams(
           LayoutParams.FILL_PARENT, LayoutParams.FILL_PARENT));
          }

在android中显示带有sqlite数据库值的表？
