Dynamic Table in Android

Now we will understand the preceding code in sections. Code Section 1 In the preceding code, we created two objects of the EditText class. In the first txt1 object we provided the reference of edittext1. In the second txt2 object we will provide the reference of edittext2. Here edittext1 and edittext2 both are the id of EditText. We used the txt1 to retrieve the number of rows and txt2. To retrieve the number of columns that are inserted by the user, we use two Table Layouts. The first is TableLayout_Create, in this layout we create a dynamic number of EditTexts (TextBoxes) and the second layout is TableLayout_Show. In this layout, we create a dynamic number of TextView. We fetch the value of each Edittext that are present in TableLayout_Create and insert it into the TextView that is present in TableLayout_Show. We also use two buttons. The first button is to Create. This button is used for creating a dynamic number of EditTexts in TableLayout_Create. Another button is Show. This button is used for fetching the data from each Editext and inserting it into a TextView. Code Section 2 In the preceding code, we created an OnClick event for the Create Button. We use two variables, Row and Col. The Row variable contains the numbers of rows and the Col variable contains the number of columns that are entered by the user into the TextViews txt1 and txt2. Then we used two loops, the outer loop creates a new row and the inner loop creates a new column final TableRow row = new TableRow(MainActivity.this). The statement creates a new Row object into the current activity. Here MainActivity is the name of our activity. Then we created a number of Edittext objects and assign some property to each Edittext object. In the internal loop, after assigning all the properties to each edittext object we assign this Edittext object to the row object. Addview is used for assigning a view into another view. At the end of the internal loop, we assigned each row to TabLayout_Create TabLayout. When we click on this button a table is created and this table will contain a number of EditTexts with a default value. Let us see an example. In the preceding example, we created a table with 4 rows and each row contains 3 columns. Each cell of the table contains an EditText control with a default value. When we click on the Show button then the value will be inserted into TabLayout_Show from TabLayout_Create.
