Here I have created EdiIexts dynamically by clicking the button, how can I take values from these EditTexts? I have seen many examples but I am unable to get values!
final LinearLayout ll=new LinearLayout(this);
ll.setOrientation(LinearLayout.VERTICAL);
Button add_btn=new Button(this);
add_btn.setText("Click to add TextViiews and EditTexts");
ll.addView(add_btn);
add_btn.setOnClickListener(new OnClickListener() {
public void onClick(View v) {
EditText et=new EditText(getApplicationContext());
ll.addView(et);
You can get dynamically created edittext's value the same way you would do with edittext of .xml file.
String value;
add_btn.setOnClickListener(new OnClickListener() {
#Override
public void onClick(View v) {
// TODO Auto-generated method stub
value = et.getText().toString();
}
});
add this code where you want to get the edittext's value
EditText et2=(EditText)ll.getChildAt(l1.getChildCount()); //make sure to create new edittext variable do not use "et"
String s=et2.getText().toString();
Declare EditText et as a Class level Member variables for your Activity,
private EditText et = null;
Now, in Button's onClick
add_btn.setOnClickListener(new OnClickListener() {
public void onClick(View v) {
et = new EditText(getApplicationContext());
ll.addView(et);
Now, you can get the EditText et values any where in your Activity scope, using
if(et != null)
String value = et.getText().toString();
try this,
LinearLayout linearLayoutForm = (LinearLayout) activity.findViewById(R.id.linearLayoutForm);
EditText edit = (EditText) linearLayoutForm.findViewById(id);
String value = edit.getText().toString();

I am working with android LinearLayout and i am adding a TextView programmicataly and then on TextView click add an EditText in View. Now I want to get data at then end on button click from all added EditTexts in layout. here is my coding through which i am working.
TextView addMoreText = new TextView(this);
addMoreText.setText("Add More Ingredients");
addMoreText.setGravity(Gravity.CENTER);
addMoreText.setPadding(20, 20, 20, 20);
addMoreText.setCompoundDrawablesWithIntrinsicBounds(0, 0, R.drawable.add, 0);
addMoreText.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
final EditText editTextItem = new EditText(SearchRecipe.this);
editTextItem.setCompoundDrawablesWithIntrinsicBounds(0, 0, R.drawable.cross, 0);
editTextItem.setPadding(20, 20, 20, 20);
editTextItem.setOnLongClickListener(new View.OnLongClickListener() {
#Override
public boolean onLongClick(View v) {
parentLayout.removeView(editTextItem);
return true;
}
});
parentLayout.addView(editTextItem, 0);
}
});
parentLayout.addView(addMoreText);
searchRecipe.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
}
});
i want to get all the data from EditText on searchRecipe click
Assign the id to the EditText:
editTextItem .setId({yourId});
Then inside searchRecipe onClick method, invoke:
EditText editTextItem = (EditText) parentLayout.findViewById({yourId});
And then use it as you want.
Add an arraylist and put the edittexts in it to keep track of them.
ArrayList<EditText> etList = new ArrayList();
In onClick of textview just add to it at the end.
etList.add(editTextItem);
In searchReciepe go through your list.
for(Edittext et : etList){
et.getText();
[...]
}
Edit: Obviously remember to remove it from the List on remove.
private int EDITTEXT_ID = 1;
private List<EditText> editTextList = new ArrayList<EditText>();
// Add Edittext programmatically in your view
private void addView() {
EditText editText = new EditText(this);
editText.setId(EDITTEXT_ID);
EDITTEXT_ID++;
editText.setText("Hello there " + EDITTEXT_ID);
editTextList.add(editText);
lnvEditText.addView(editText); // lnvEdittext is my LinearLayout which is added in XML file
}
// Get values of every Edittext on click of button
for(int i=0; i<editTextList.size(); i++) {
Log.e("All Values=", editTextList.get(i).getText().toString());
}
i have an app that make check box dynamically.

...
public int i2 = 0;
...
final EditText et1 = (EditText) findViewById(R.id.editText1);
final Button bnext = (Button) findViewById(R.id.button1);
//
final LinearLayout ll = new LinearLayout(this);
ll.setOrientation(LinearLayout.VERTICAL);
//
bnext.setOnClickListener(new OnClickListener() {
#Override
public void onClick(View v) {
//getting text from edit text
String str_et1 = et1.getText().toString();
do {
CheckBox cb = new CheckBox(getApplicationContext());
cb.setId(i2);//set id to each checkbox
cb.setText(str_et1);//set text to each checkbox
ll.addView(cb);
} while (bnext.isDirty());//add when ever i clicked
i2++;//this the counter
}
});
Try this code -
final EditText et1 = (EditText) findViewById(R.id.editText1);
final Button bnext = (Button) findViewById(R.id.button1);
//
final LinearLayout ll = new LinearLayout(this);
LayoutParams params =
new LinearLayout.LayoutParams(
LayoutParams.WRAP_CONTENT,
LayoutParams.WRAP_CONTENT);
ll.setOrientation(LinearLayout.VERTICAL);
ll.setLayoutParams(params);
//
bnext.setOnClickListener(new OnClickListener() {
#Override
public void onClick(View v) {
//getting text from edit text
String str_et1 = et1.getText().toString();
do {
CheckBox cb = new CheckBox(getApplicationContext());
cb .setLayoutParams(params);
cb.setId(i2);//set id to each checkbox
cb.setText(str_et1);//set text to each checkbox
ll.addView(cb);
} while (bnext.isDirty());//add when ever i clicked
i2++;//this the counter
}
});
Hope this code helps you!!
if its not working please let me know i will try to help more.
A check box alone is not a visible component. You will need to have a LayoutParam, then attach the checkbox to it to make it visible.
I am making an android application. I have a TextField and a button. Based on the value of the textfield, as soon as the user clicks the button I want to make something. I have the code:
EditText et = (EditText)findViewById(R.id.editText1);
String value = et.getText().toString();
ImageButton ib = (ImageButton)findViewById(R.id.imageButton1);
ib.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
if (value = "a" ) {
//do something }
}
});
This however doesn't compile, saying "Cannot refer to a non-final variable value inside an inner class defined in a different method". Is there any way to fix this? Thanks a lot
Use
final String value = et.getText().toString();
and then use,
if(value.equals("a") {
}
If you want to compare the value of a string you should use the "equals" method instead of "=".
The code will look like this:
EditText et = (EditText)findViewById(R.id.editText1);
final String value = et.getText().toString();
ImageButton ib = (ImageButton)findViewById(R.id.imageButton1);
ib.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
if (value.equals("a") ) {
//do something }
}
});
final String value = et.getText().toString();
In my application,on press of a button "Add contact" phone book gets open and then user selects a contact that get displayed in Edittext View and when another button "Add More Contacts" is pressed, a another Edit-Text View gets displayed on the top for which i can again select the contact from phone book. But the problem that i am facing is that i want that user can only add up to 5 Edit Text .
I am using the following code, but its force crashing the application. Please help.
And also i want the Edit Text Views to be non editable, for which i tried editable=false but its working only for the first Edit Text View not on the other Views, that user adds afterwards.
int id = 1;
layoutLinear = (LinearLayout) findViewById(R.id.mLayout);
btn_addmore_cntct = (Button) findViewById(R.id.baddmorecontacts);
btn_addmore_cntct.setOnClickListener(OnClick());
EditText editview = new EditText(this);
editview.setText("Add more");
editview.setEnabled(false);
editview.setFocusable(false);
}
// implementing OnClickListener OnClick() method for "btn_addmore_cntct"
// button
private OnClickListener OnClick() {
// TODO Auto-generated method stub
// changing return type "null" to "new OnClickListner"
return new OnClickListener() {
#Override
public void onClick(View v) {
// TODO Auto-generated method stub
if(layoutLinear.getChildCount()>5){
}else{
final EditText tab = new EditText(getApplicationContext());
tab.setLayoutParams(new LayoutParams(LayoutParams.FILL_PARENT,LayoutParams.WRAP_CONTENT));
tab.setId(id);
id++;
layoutLinear.addView(tab,0);
tab.requestFocus();
}
Just check number of layoutLinear child
if(layoutLinear.getChildCount()>5){
//nothing to do
}else{
//create new EditText and add to layoutLinear
}
user this code to disable EditText
edittext.setEnabled(false);
edittext.setFocusable(false);
You can use following way.
int temp;
public void onCreate(Bundle savedinstance) {
super.onCreate(savedinstance);
setContentView(R.layout.yourlayout);
temp=1;
layoutLinear = (LinearLayout) findViewById(R.id.mLayout);
btn_addmore_cntct = (Button) findViewById(R.id.baddmorecontacts);
btn_addmore_cntct.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
// TODO Auto-generated method stub
if(temp<=5){
EditText tab = new EditText(getApplicationContext());
tab.setLayoutParams(new LayoutParams(LayoutParams.FILL_PARENT,LayoutParams.WRAP_CONTENT));
tab.setEnabled(false);
tab.setFocusable(false);
layoutLinear.addView(tab);
temp++;
}else{
//Print message to user Cant add more editText.
}
}
});
}
Let me know its working or not.
I'm new in android and i have created editText dynamically with the following code while clicking add new button.Is it possible to add a delete button near editText so that each while clicking the delete respective editText will be removed?
btnAddNew.setOnClickListener(new OnClickListener() {
public void onClick(View v) {
LinearLayout rAlign = (LinearLayout)findViewById(R.id.lId);
EditText newPass = new EditText(getApplicationContext());
allEds.add(newPass);
newPass.setHint("Name of Label");
newPass.setLayoutParams(new LayoutParams(LayoutParams.WRAP_CONTENT, LayoutParams.WRAP_CONTENT));
newPass.setWidth(318);
newPass.setTextColor(Color.parseColor("#333333"));
newPass.setId(textb);
rAlign.addView(newPass);
MY_BUTTON ++;
addSpinner();
}
});
Yes, create your remove button at the same time as your EditText and use the removeView() method just like the addView() method, maybe like this:
btnAddNew.setOnClickListener(new OnClickListener() {
public void onClick(View v) {
...
rAlign.addView(newPass);
MY_BUTTON ++;
addSpinner();
Button btnRemoveOld = new Button(this);
btnRemoveOld.setId(32); // arbitrary number
btnRemoveOld.setOnClickListener(new OnClickListener() {
public void onClick(View v) {
LinearLayout rAlign = (LinearLayout)findViewById(R.id.lId);
rAlign.removeView(findViewById(textb));
}
});
// You will need to set parameters to define how the button looks
// and where it is in relation to the EditText here
rAlign.addView(btnRemoveOld);
}
});
