I have an activity in which I have created a table dynamically. The table is populated from a SQLite database. Onclick the table header the table is getting sorted accordingly.
Everything is working fine, now my requirement is to change the text color of the table header textview when it is clicked. The text color is not getting changed.
This is the a method which is populating the table:
//Time ascending method
public void populateTableTimeAscending()
{
getTimeNameTimeAsc();
getStudentNameTimeAsc();
follow_up_table.removeAllViews();
//---------------Table Header-----------------------------------------------
TableRow followup_tr_head = new TableRow(this);
followup_tr_head.setId(10);
followup_tr_head.setBackgroundResource(R.drawable.list_header);
followup_tr_head.setLayoutParams(new LayoutParams(
LayoutParams.FILL_PARENT,
LayoutParams.WRAP_CONTENT));
TextView time_name_title = new TextView(this);
time_name_title.setId(20);
time_name_title.setText("Time");
time_name_title.setTextColor(Color.WHITE);
time_name_title.setPadding(5,5,5,5);
followup_tr_head.addView(time_name_title);// add the column to the table row here
time_name_title.setTextSize(12);
TextView student_name_title = new TextView(this);
student_name_title.setId(20);
student_name_title.setText("Student Name");
student_name_title.setTextColor(Color.WHITE);
student_name_title.setPadding(5,5,5,5);
followup_tr_head.addView(student_name_title);// add the column to the table row here
student_name_title.setTextSize(12);
//----------------------On click time_name_title---------------------------------------
time_name_title.setOnClickListener(new OnClickListener() {
#Override
public void onClick(View v) {
// TODO Auto-generated method stub
//makeAToast("Hello!");
populateTableTimeDescending();
}
});
//----------------------On click time_name_title---------------------------------------
//----------------------On click student_name_title---------------------------------------
student_name_title.setOnClickListener(new OnClickListener() {
#Override
public void onClick(View v) {
// TODO Auto-generated method stub

populateTableNameAscending();
}
});
//----------------------On click student_name_title---------------------------------------
follow_up_table.addView(followup_tr_head, new TableLayout.LayoutParams(
LayoutParams.FILL_PARENT,
LayoutParams.WRAP_CONTENT));
//--------------- Table Header-----------------------------------------------
Iterator itr = time_name_list_time_asc.iterator();
Iterator itr2 = student_name_list_time_asc.iterator();
while(itr.hasNext())
{
while(itr2.hasNext())
{
//----------------table body------------------------------------------
followup_tr_data = new TableRow(this);
followup_tr_data.setId(10);
followup_tr_data.setBackgroundResource(R.drawable.grey_list_bg);
followup_tr_data.setLayoutParams(new LayoutParams(

LayoutParams.WRAP_CONTENT));
final TextView timeNameText = new TextView(this);
timeNameText.setId(20);
timeNameText.setText(Html.fromHtml(itr.next().toString()));
timeNameText.setTextColor(Color.BLACK);
timeNameText.setPadding(5,5,5,5);
timeNameText.setTextSize(10);
followup_tr_data.addView(timeNameText);// add the column to the table row here
final TextView StudentNameText = new TextView(this);
StudentNameText.setId(20);
StudentNameText.setText(Html.fromHtml(itr2.next().toString()));
StudentNameText.setTextColor(Color.BLACK);
StudentNameText.setPadding(5,5,5,5);
StudentNameText.setTextSize(10);
followup_tr_data.addView(StudentNameText);// add the column to the table row here
follow_up_table.addView(followup_tr_data, new TableLayout.LayoutParams(
LayoutParams.FILL_PARENT,
LayoutParams.WRAP_CONTENT));
//----------------table body------------------------------------------
}
}
}
Inside time_name_title.setOnClickListener(new OnClickListener() I have tried to change the text color which did not happen.

You can also use this:
textview.setOnTouchListener(new View.OnTouchListener() {
#Override
public boolean onTouch(View v, MotionEvent event) {
switch (event.getAction()) {
case MotionEvent.ACTION_DOWN:
textview.setTextColor(Color.BLUE);
break;
case MotionEvent.ACTION_UP:
textview.setTextColor(Color.BLACk);
break;
}
return false;
}
});
Another way change text color on click is:
Add resource file:
XML file saved at res/color/button_text.xml:
<?xml version="1.0" encoding="utf-8"?>
<selector xmlns:android="http://schemas.android.com/apk/res/android">
<item android:state_pressed="true"
android:color="#ffff0000"/> <!-- pressed -->
<item android:state_focused="true"
android:color="#ff0000ff"/> <!-- focused -->
<item android:color="#ff000000"/> <!-- default -->
</selector>
And set as textColor for you widget:
<Button
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:text="#string/button_text"
android:textColor="#color/button_text" />
For more dital look at google guide
Insure that you're trying to change text color in proper TextView and try to call setTextColor after populateTableTimeDescending();
final TextView tv = new TextView(this);
tv.setText("Sample TextView");
rl = (RelativeLayout) findViewById(R.id.rl);
rl.addView(tv);
tv.setOnClickListener(new OnClickListener() {
#Override
public void onClick(View v) {
populateTableTimeDescending();//since you are setting the color of the TextView back to same(white) again in this method, set the color of the textView after calling the method.
tv.setTextColor(Color.parseColor("#FF0000")); //**edited**
}
});
You are trying to set the same color. Check it out.
Please change the color first in any of the method.
--------------edit-------------
then do textview.setColor(Color.BLUE); before populateTableTimeDescending(); in your onClick();
Here, after four digits, you can set whichever color you'd like using a hexadecimal color code:
time_name_title.setTextColor(0xffffffff);

Please help.
You need to add OnClickListner Interface to your activity and then add all dynamic view to setOnClickListner and finally you can catch click event for all view inside onClick(View view) method.
Try this
public class MainScreen extends Activity implements OnClickListener {
int i = 10; // input no of row
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main); // set here your layout xml name
//TableLayout tl = new TableLayout(MainScreen.this);
TableLayout tl = (TableLayout) findViewById(R.id.table);
for (int k = 0; k < i; k++) {
TableRow tr = new TableRow(MainScreen.this);
tr.layout(0, 0, 0, 0);
TextView ids = new TextView(MainScreen.this);
ids.setText(loc_id[k]);
ids.setPadding(30, 15, 30, 15);
TextView loc = new TextView(MainScreen.this);
loc.setText(loc_name[k]);
loc.setPadding(30, 15, 30, 15);
tr.setPadding(0, 1, 0, 0);
tr.addView(ids);
tr.addView(loc);
tr.setId(k); // here you can set unique id to TableRow for
// identification
tr.setOnClickListener(MainScreen.this); // set TableRow onClickListner
tl.addView(tr, new TableLayout.LayoutParams(
LayoutParams.WRAP_CONTENT, LayoutParams.WRAP_CONTENT));
}
//setContentView(tl);
}
#Override
public void onClick(View v) {
// TODO Auto-generated method stub
int clicked_id = v.getId(); // here you get id for clicked TableRow
// now you can get value like this
String ids = loc_id[clicked_id];
String loc = loc_name[clicked_id];
}
}
i made a program and in my program, i have an editText. How can i get the value of my edittext...please help me i can't get excellent.getText().toString();.
Is there a remedy to get the value of my edittext? Help me please thank you in advance..
here are my codes..
TableLayout table = new TableLayout(getApplicationContext());
table.setVerticalScrollBarEnabled(true);
table.setPadding(10, 10, 10, 10);

TextView txt = new TextView(getApplicationContext());
tableRow.addView(txt);
tableRow.setBackgroundColor(Color.GRAY);
txt.setText("Excellent ");
table.addView(tableRow);
int j = 0;
for (j = 1; j <= count; j++) {

I used the code below to create a TableRow with content dynamically. It works good but I wish to get the values in the TableRow. Here is the sample code (I got it from Google), it has two text values in the TableRow. When I click the TableRow at any position it gives the corresponding value in the TableRow (I wish something similar to a ListView).

In the code above some lines are commented, these lines are what I already tried to get the row values but it failed. Can anyone help me with this?
I guess you're talking about getting those values on a TableRow click. If this is the case you could add a listener to your TableRow and use getChildAt to get a hold of the two TextViews and get the data:
//...
tr.setOnClickListener(new View.OnClickListener() {
public void onClick(View view) {
TableRow t = (TableRow) view;
TextView firstTextView = (TextView) t.getChildAt(0);
TextView secondTextView = (TextView) t.getChildAt(1);
String firstText = firstTextView.getText().toString();
String secondText = secondTextView.getText().toString();
}
});
//...
To get data from textview first u need to identify its parent from that u need to get your textView child position then u can get data from it... Here is a sample
String myText;
((TextView) findViewById(R.id.tv)).setOnClickListener(new OnClickListener() {
#Override
public void onClick(View v) {
TableRow tablerow = (TableRow)v.getParent();
TextView items = (TextView) tablerow.getChildAt(2);
myText = items.getText().toString();
}
});
spinnerSelection.setOnItemSelectedListener(new AdapterView.OnItemSelectedListener() {
#Override
public void onItemSelected(AdapterView<?> parent, View view, int position, long id) {
TableRow selectedRow = (TableRow)spinnerSelection.getParent();
int index = tableLayout.indexOfChild(selectedRow);
Here index is the selected row index value and you can call all the views under the parent row (selectedRow) like the below set of lines.
Button roomNo = (Button) selectedRow.getChildAt(0);
Spinner selectionA = (Spinner) selectedRow.getChildAt(1);
Spinner selectionB = (Spinner) selectedRow.getChildAt(2);
Happy Coding!!
