Question

I am displaying 2 separate tables in a screen.
There is no problem displaying the first table.
Referring to TableLayout second_table , TableRow tableRow5 , Textfield(s) textView51 , textView52 , textView53

TextFields are basically the columns. Three columns to be displaying
First Name , Last Name , Age.I need to dynamically set the values after fetching that from the server.

I am facing the following exception:
java.lang.IllegalStateException: The specified child already has a parent. You must call removeView() on the child’s parent first.

I am populating the second table using the following lines of code:

public void onCreate(Bundle savedInstanceState) {
 super.onCreate(savedInstanceState);
 setContentView(R.layout.employee_details);
 TableLayout tableLay = (TableLayout) findViewById(R.id.second_table);
 TableRow tableRow = (TableRow) findViewById(R.id.tableRow5);
 TextView fNameTxtView = (TextView) findViewById(R.id.textView51);
 TextView lNameTxtView = (TextView) findViewById(R.id.textView52);
 TextView ageTxtView = (TextView) findViewById(R.id.textView53);
 for(int count = 0; count < tempArrList.size() ; count++){
 fNameTxtView.setText(tempArrList.get(temp.get(0)));
 lNameTxtView.setText(tempArrList.get(temp.get(1)));
 ageTxtView.setText(tempArrList.get(temp.get(2)));
  tableRow.addView(fNameTxtView);
  tableRow.addView(lNameTxtView);
  tableRow.addView(ageTxtView);
  tableLay.addView(tableRow); // Add the new row to our tableLayout
 }
}

I have tried few variations too , but unable to solve the problem.
Any suggestions welcome.

The layout xml follows:
employee_details.xml

<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="fill_parent" android:layout_height="fill_parent">
    <include android:id="@+id/header" layout="@layout/activity_header" />

Answer 1

In your for statement you are using the same TextView and TableRow objects and every time you do :

tableRow.addView(fNameTxtView);
  tableRow.addView(lNameTxtView);
  tableRow.addView(ageTxtView);
  tableLay.addView(tableRow);

you insert in your layout the same TextViews fNameTxtView, lNameTxtView, ageTxtView.
To avoid this you could create objects dynamically in your for statement like this:

for(int count = 0; count < tempArrList.size() ; count++){
TextView fNameTxtView = new TextView(this);
 fNameTxtView.setText(tempArrList.get(temp.get(0)));
TextView lNameTxtView= new TextView(this);
 lNameTxtView.setText(tempArrList.get(temp.get(1)));
TextView ageTxtView = new TextView(this);
 ageTxtView.setText(tempArrList.get(temp.get(2)));
TableRow tableRow = new TableRow(this);
  tableRow.addView(fNameTxtView);
  tableRow.addView(lNameTxtView);
  tableRow.addView(ageTxtView);
  tableLay.addView(tableRow); // Add the new row to our tableLayout
 }

edit: of course you could add IDs for the TextViews if you want do more work on them.
