changing the button text from the edittext state

I have one button and 1 edittext. The button is set to "change", and EditText is enable-false. When you click on a button, its text is changed to "save", and edit text is available for input. After a second press, the text changes to "change" again, and the button becomes Enable-false.
how to implement it?

Use this onClickListener on your button -
Button yourButton = (Button) view.findViewById(R.id.button)
EditText yourEditText = (EditText) view.findViewById(R.id.edittext)
yourButton.setOnClickListener(new OnClickListener() {
#Override
public void onClick(View v) {
if (!yourEdittext.isEnabled()){
yourButton.setText("Save");
yourEditText.setEnabled(true);
counter++;
}else if (yourEdittext.isEnabled()){
yourButton.setText("Change again");
yourButton.setEnabled(false);
}
}
});
Make sure to set the initial button's text and the edit text disabled for the starting point

setting edit text visible each time button is pressed

Actually I want that each time I press the button 2 edit text is set visible,and same thing should happen each time the button is pressed.
Basically whenever user presses the button 2 edittext should appear(any loop concept?)
Please suggest.ThankYou :)

Just add a click listener to the button, and change the visibility of editText into it :
button.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
editTextName.setVisible(true);
}
});

Not sure if i got your question right but you can use android:setvisibility=gone in xml editext fields and then in your button onclick use
edittext.setVisibility(View.VISIBLE);
to make the edittext fields visible.

Just set the initial visibility in the code or in the xml to GONE
and then add onClickListener
android:visibility="gone"
//or
btn2.setVisibility(View.GONE)
btn2.setOnClickListener(new View.OnClickListener(){
e#Override
public void onClick(View view) {
editText.setVisible(true);
}
});

You want to populate an edittext each time a button is pressed ?
Create a layout for your edittext:
public EditText createEditText() {
final LayoutParams lparams = new LayoutParams(LayoutParams.MATCH_PARENT, LayoutParams.WRAP_CONTENT);
final EditText edittext = new EditText(this); Editext.setLayoutParams(lparams);
return edittext; }
And then add edittexts to your layout:
rl.addView(createEditText());

If I understand correctly, you want to set edit text to visible on the press of a button. This can be done by following steps:
In your Main Class:
Create 2 new EditText variable:
EditText myEditText1;
EditText myEditText2;
Create a new method to be called on button click:
void buttonClick(View view){
//Get References
myEditText1 = (EditText) findViewById(R.id.first_edit_text);
myEditText2 = (EditText) findViewById(R.id.second_edit_text);
//Set visible
myEditText1.setVisibility(View.VISIBLE);
myEditText2.setVisibility(View.VISIBLE);
//Set edit texts to empty string to reset ("Recreation")
myEditText1.setText("");
myEditText2.setText("");
}
In your xml:
Add the onClick attribute to your Button:
android:onClick="buttonClick";
Add the id to your EditTexts:
android:id="#+id/first_edit_text"
android:id="#+id/second_edit_text"
Now, Whenever the button is pressed, the Edit Text becomes visible, no loop is required. And if you also want to be hidden before pressing button, add:
android:visibility="invisible"
Sources: setVisibility, onClick

EditText and button(When button is pressed value shoud be entered in edittext field)

Am creating a calculator,i want when button is pressed for example say 5,how to set value 5 to the button and if that button is clicked . The value should be printed in edit text!!
My source code:
ed=(EditText)findViewById(R.id.editText);
b=(Button)findViewById(R.id.button);
gt=Double.parseDouble(ed.getText().toString());
ed.setText(""+gt);
}

If I understand your question correctly:
U got some buttons with text or digits.
And if someone presses one of those buttons u want to display the text of the button in your editText box?
If so u can do something like the following:
EditText myEditText = (EditText) findViewById(R.id.editText);
Button myButton0= (Button) findViewById(R.id.button0);
myButton0.setOnClickListener( new OnClickListener() {
#Override
public void onClick(View v) {
//Get the button text and display it in the editText
//This will replace all text in the editText box
myEditText.setText(myButton0.getText().toString());
//Or (Thanks to #cherry-wave)
//This will append the text, instead of replacing
myEditText.setText(myEditText.getText() + myButton0.getText().toString());
}
});
Or (to handle all your buttons with only one method):
Add the following line to all your buttons in your layout xml:
android:onClick="onClick"
And place the following method in your activity class file:
//Your onClick method
public void onClick(View v) {
Button myButton = (Button)v;
//Don't forget to declare your edittext
//This will replace all text in the editText box
myEditText.setText(myButton.getText().toString());
//Or (Thanks to #cherry-wave)
//This will append the text, instead of replacing
myEditText.setText(myEditText.getText() + myButton.getText().toString());
}
Hope this helps u out.

Take the value from button and add to edittext .
Just like this .
editText.setText(btnFive.getText().toString());
Before button click get value from editText .
String edtValue = editText.getText.toString();
Than set editText.setText(edtValue+btnFive.getText().toString());

How can I change the text of a button at runtime on Android?

I want to write a simple example where I can change the text of a button at run time.
Basically, I am extracting the text from "EditText" view and trying to populate the contents of the button "OnClick" event.
However, the system crashes.
/** Called when the user clicks the Send button */
public void sendMessage(View view) {
// Do something in response to button
Button btn = (Button) findViewById(R.id.button_message);
EditText editText = (EditText) findViewById(R.id.edit_message);
String message = editText.getText().toString();
btn.setText(message);
}
What am I doing wrong?
a) Should I be registering an Listener on the button for this purpose?
b) Is this another "Activity" and should I be creating an Intent for this?

Button btn = (Button) findViewById(R.id.button_message);
EditText editText = (EditText) findViewById(R.id.edit_message);
btn.setOnClickListener(new OnClickListener() {
#Override
public void onClick(View v) {
String message = editText.getText().toString();
btn.setText(message);
}
});
Inside the onclick events u get the string from edittext and set it to the button it will work

Android keyboard appear automatically

I have a disabeld EditText and an "Edit name" button next to it. I press the "Edit name" button and after i make the EditText enabled again i'd like for the keyboard to popup so the user can insert the text (without him needing to "click" the EditText because i'm using that action for saving what he just entered and making the EditText disabled again).
How can this be accomplished?
Thanks,
Andrei

in the textView onclick method put this code.
TextView text = (TextView)findViewById(R.id.youris);
text.setOnClickListener(new View.OnClickListener() {
public void onClick(View arg0) {
EditText et = (EditText)findViewById(R.Id.yourid);
et.requestfocus();
}
}
