    <p>Good Morning everyone,</p> <p>I'm facing yet another problem in my path of learning Android. I made a dynamic TableLayout with the content of an CSV file. I need that when I click/touch a row in the table, the color should change, and later with a click of a button get the content of the same line. Now I'm stucked with the first part and of course I have no clue about how to get the data of the row.</p> <p>I declared the table inside a LinearLayout that is also inside of a ScrollView in my layout with the following properties:</p> <pre><code> &lt;ScrollView android:id="@+id/scrollMotors" android:layout_width="fill_parent" android:layout_height="wrap_content" android:layout_alignParentLeft="true" android:layout_alignParentRight="true" android:layout_alignParentTop="true" android:layout_alignParentBottom="true" android:layout_marginLeft="50dp" android:layout_marginRight="50dp" android:layout_marginTop="90dp" android:layout_marginBottom="50dp" &gt; &lt;LinearLayout android:id="@+id/layoutMotors" android:layout_width="fill_parent" android:layout_height="wrap_content" &gt; &lt;TableLayout android:id="@+id/tableMotors" android:layout_width="fill_parent" android:layout_height="wrap_content" android:layout_gravity="center_vertical" android:clickable="true" android:focusable="true" android:focusableInTouchMode="true" android:gravity="center_vertical" android:stretchColumns="*" &gt; &lt;/TableLayout&gt; &lt;/LinearLayout&gt; &lt;/ScrollView&gt; </code></pre> <p>After in my java code, I declared the creation of the line:</p> <pre><code> //Initialization of my table my_tableMotors = (TableLayout) findViewById(R.id.tableMotors); //This is an ArrayList&lt;ArrayList&lt;String&gt;&gt; that contains the lines of the CSV file, //I use this variable as a dynamic Matrix because my CSV file can change its dimensions. m = valuesFile.size(); for (n = 0 ; n &lt; m ; n++) { //Declaration and initialization of my rows final TableRow line = new TableRow(MotorActivity.this); //Setting the parameters of my row line.setLayoutParams(new LayoutParams(LayoutParams.FILL_PARENT,LayoutParams.WRAP_CONTENT)); line.setFocusable(true); line.setFocusableInTouchMode(true); line.setClickable(true); //Initialization of my TextViews that are gonna be the content of each one of the rows in the dynamic TableLayout myCol1 = new TextView(MotorActivity.this); myCol2 = new TextView(MotorActivity.this); myCol3 = new TextView(MotorActivity.this); myCol4 = new TextView(MotorActivity.this); j = valuesFile.get(n).size(); for (i = 0 ; i &lt; j ; i++) { switch(i) { case 0: if (n == 0) { myCol1.setText("Line"); } else { myCol1.setText(valuesFile.get(n).get(i)); //Sets value for the column } line.addView(myCol1); break; case 1: myCol2.setText(valuesFile.get(n).get(i)); //Sets value for the column line.addView(myCol2); break; case 2: myCol3.setText(valuesFile.get(n).get(i)); //Sets value for the column line.addView(myCol3); break; case 3: myCol4.setText(valuesFile.get(n).get(i)); //I use this variable for some other purpose break; } } my_tableMotors.addView(line); } my_tableMotors.setOnClickListener(new View.OnClickListener() {public void onClick(View v) {onClickedRow(); }}); } </code></pre> <p>From what I've seen and read here, the best is to use a setOnClickListener and that's what I did using a bit of two different answers that I found here:</p> <pre><code> public void onClickedRow() { m = my_tableMotors.getChildCount(); for (n = 0 ; n &lt; m ; n++) { if (my_tableMotors.getChildAt(n).hasFocus()) { my_tableMotors.setBackgroundColor(myColor); } } } </code></pre> <p>Now I can't get any focus at the tableLayout at all, so please if you see something wrong in my code or if you know how to help me with this I would appreciate it a lot!!!!</p> <p>Many thanks in advance :).</p> <p><strong>EDIT 1</strong></p> <p>I found the way to get the focus. I changed the method not to the whole TableLayout but only to the TableRow, so ended up as this:</p> <p>*<strong><em>Before</em>*</strong></p> <pre><code> my_tableMotors = (TableLayout) findViewById(R.id.tableMotors); m = valuesFile.size(); for (n = 0 ; n &lt; m ; n++) { //Declaration and initialization of my rows final TableRow line = new TableRow(MotorActivity.this); /*Other declarations*/ j = valuesFile.get(n).size(); for (i = 0 ; i &lt; j ; i++) { /*Code*/ } my_tableMotors.addView(line); } my_tableMotors.setOnClickListener(new View.OnClickListener() {public void onClick(View v) {onClickedRow(); }}); } </code></pre> <p>*<strong><em>After</em>*</strong></p> <pre><code> my_tableMotors = (TableLayout) findViewById(R.id.tableMotors); m = valuesFile.size(); for (n = 0 ; n &lt; m ; n++) { //Declaration and initialization of my rows final TableRow line = new TableRow(MotorActivity.this); /*Other declarations*/ j = valuesFile.get(n).size(); for (i = 0 ; i &lt; j ; i++) { /*Code*/ } line.setOnClickListener(new View.OnClickListener() {public void onClick(View v) {onClickedRow(); }}); my_tableMotors.addView(line); } </code></pre> <p>I also made the change on how to set the color of the line:</p> <p>*<strong><em>Before</em>*</strong></p> <pre><code>my_tableMotors.setBackgroundColor(myColor); </code></pre> <p>*<strong><em>After</em>*</strong></p> <pre><code>my_tableMotors.getChildAt(n).setBackgroundResource(R.drawable.myColor); </code></pre> <p>Now I'm busy finding out how to get the data from the TableRow. As soon as I get that solve or an answer from you I think I have my problem solved!!!</p> <p><strong>EDIT 2</strong></p> <p>With the help of @Luksprog I could find an answer to my problem of retrieving the content!!! I did used the next code using his solution:</p> <pre><code> public void onClickedRow() { TableRow clickedRow = new TableRow(MotorActivity.this); m = my_tableMotors.getChildCount(); for (n = 1 ; n &lt; m ; n++) { if (my_tableMotors.getChildAt(n).isFocused()) { my_tableMotors.getChildAt(n).setBackgroundResource(R.drawable.highlightTableRow); clickedRow = (TableRow) my_tableMotors.getChildAt(n); j = clickedRow.getChildCount(); for (i = 0; i &lt; j ; i++) { switch(i) { case 0: myField1 = (TextView) clickedRow.getChildAt(i); break; case 1: myField2 = (TextView) clickedRow.getChildAt(i); break; case 2: myField3 = (TextView) clickedRow.getChildAt(i); break; } } } } } </code></pre>

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
