How to get text from edit text in Android

Okay.. I have 2 classes :-
1. Apple.class
2. Banana.class
And 2 .XML file:-
1. ear.xml
2. nose.xml
Now, I want to add a edit text box in apple.class
But I want to print that text that user input in banana.class

1) Get the entered value from edittext by the following
String content = EditText.getText().toString();
2) Then pass the string "content" to the next Activity using Intent.
Intent i = new Intent(Apple.this,Banana.class);
i.putstring("EditTextValue",content);
startactivity(i);
3) Get the data in Banana class and set to a textview.

Use the following code when clicked on the button , send data from AppleActivity to BananaActivty :
String value = edittext.getText().toString().trim(); //get text from editText
Intent i=new Intent(FirstDemo.this,SecondDemo.class);
i.putExtra("key", value);//you can add other key value
startActivity(i);
then in other class you have to get value from Intent like below:
String value = getIntent().getStringExtra("key"));
Hope to be useful to you

//one activity(FirstDemo)
EditText ed1,ed2;
String st="",st2="";
//onCreate method:-
st=ed1.getText().toString().trim();
st2=ed2.getText().toString().trim();
//then click on button
Intent i=new Intent(FirstDemo.this,SecondDemo.class);
i.putExtra("id", st);
i.putExtra("u_email", st2);
startActivity(i);
//then next Activity(SecondDemo):-
Edittext e1,e2;
Intent j = getIntent();
e1.setText(j.getStringExtra("id"));
e2.setText(j.getStringExtra("u_email"));

Hiding edit text in onCreate, but then not storing values once values entered for EditText, clipEx has text data false

The app crashes when the button is selected which uses the values converted from edit texts. Tried multiple ways to move the part edittext = R.ids .. to try and make sure the edittexts picks new values after the oncreate first runs.
Think the calculation part causes the crash because its trying to perform a calculation with stored values from the edit text when the value is false from the first time the edit text gets the R.ids... in the onCreate method.
needed hide/display editText based off a radio button setonCheckedChangeListener in the onCreate method. So edittext = R.ids .. set in this method, the app does not crash at runtime like it would if I moved the edittext = R.ids .. to the testFunction method.
EditText editTextValue;
EditText editTextValue2;
double amount;
protected void onCreate(){...
//Get edittext field parameters
editTextValue = (EditText) findViewById(R.id.editText_weight_kg);
//listener to switch editTexts on which radio button selected in units group
unitsRG.setOnCheckedChangeListener(new RadioGroup.OnCheckedChangeListener() {
#Override
public void onCheckedChanged(RadioGroup group, int checkedId) {
if (checkedId == R.id.imperial) {
editTextValue2.setVisibility(View.VISIBLE);
editTextValue.setVisibility(View.GONE);
}
void testFunction(View view){
String stringValue = editTextValue..getText().toString();
//check value as long as its not empty for the edit text , save it
if (editTextValue.getText().length() > 0) {
amount = Integer.parseInt(stringValue);
Log.e("MainActivity", " " + amount);
}
}
but now when I run the app I get this error in the long cat
enter image description here
E/ClipboardServiceEx﹕ clipEx is android.sec.clipboard.ClipboardExManager#1f70b420
E/ClipboardServiceEx﹕ clipEx has text data : false
here is the xml for one of the edit texts
<EditText
android:id="#+id/editText_weight_lb"
style="#style/EditTextViewStyle"
android:visibility="visible"/>
In the editTextStyle , I set the textCursorDrawable to null to try and have different colors for the pointer and underline colors. Not sure if this could also be affecting the editTextView storing the value
<item name="android:textCursorDrawable">#null</item>
I also tried setting edittext = R.ids in the testfunction and in the onCreate method. See if the editTexts would store the values the user enters rather than keeping the empty values when onCreate initially run.
I still got the same clipEx has text data:false error after trying this.
I searched the logcat error "clipEx has text data: false" and found something regarding samsung memory leaks.
https://github.com/square/leakcanary/issues/133
I am using a samsung galaxy for testing. I feel the issue is more with where I'm setting the edittexts to the R.ids thats causing the issue.
I saw the post for checking to make sure valid value entered for edittext.
Issue with empty EditText
How to Check whether a value is entered in editexts before submitting?
will add the check after finding out why values are not getting stored/ still remaining false.
Thanks

well I tried a different approach to implement the method.
I placed a button in the OnCreate method to define the event handlers against the buttons:
public void onCreate(Bundle savedInstanceState)
{
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
Button calculate = (Button)findViewById(R.id.calculate);
calculate.setOnClickListener(new View.OnClickListener(){
String stringValue = editTextValue.getText().toString();
//check value as long as its not empty for the edit text , save it
if (editTextValue.getText().length() > 0) {
amount = Integer.parseInt(stringValue);
Log.e("MainActivity", " " + amount);
}
.....
.....
}
}
By using the button method in the OnCreate, when I ran the app, errors would actually come up on the Integer.parseInt() method call. Turns out that even though the editTexts that I was entering text for did not have text values, the other editTexts still had strings for the text, so this would cause the app to crash.
<EditText...
android:text="kg"/>
I took out the text values. It worked again.
I also took out this line in the style sheet for the editText. This was to change the editText border color, cursor color, or line.
<item name="android:textCursorDrawable">#null</item>
I tried the public void testFunction() approach which I had used before, the app works, but the clipEx has text data : false continues to show up.
But the app works now with either the Button method in onCreate or as a public void testFunction() approach.

SetText in EditText Android error

I want to setText in EditView but it will error. I dont know why.
This is on OnCreate function.
name = (EditText) findViewById(R.id.input_name);
String editname = String.valueOf(getName());
MessageTo.message(this,editname);
name.setText(editname);
The string i will set in EditText name.
public String getName(){
int id = 1;
String data=dbhandler.getName(id);
return data;
}
If i remove this code from the OnCreate function
name.setText(editname);
It will have no error. The MessageTo.message code is where it pops a dialog of the String editname. It will show the String editname.
So i put back the code and change it into this code,
name.setText("testing");
But it still won't work.
I dont know why though. All other sources have EditText.setText("String") as how to setText in EditText but it won't work in my case.
LOGCAT ERROR:
09-20 21:00:36.677 1436-1436/? E/AndroidRuntime﹕ FATAL EXCEPTION: main
java.lang.RuntimeException: Unable to start activity ComponentInfo{com.organizer/com.organizer.ManageProfileActivity}: java.lang.NullPointerException

Your EditText name appears to be null. In your onCreate method, make sure you are calling setContentView(R.layout.YOUR_LAYOUT) where the layout parameter is an XML layout containing your EditText with the ID R.id.input_name.
You assign it later on with
name = (EditText) findViewById(R.id.input_name);
but if the layout does not contain this ID, name will be null, thus causing your error.

It is correct that you should be using the setText() method on the EditText.
Everything looks correct in terms of your codes, so I would suggest to check for the following things:
Are you calling setText anywhere else?
Is the id of your EditText correct (Is the id of your EditText input_name)
Are you sure you are looking at the right activity.
Are you initializing your name variable in the right scope? (Outside the onCreate Method)

Declare the EditText in the xml file
Find the EditText in the activity
Set the text in the EditText
And If you check the docs for EditText, you'll find a setText() method. It takes in a String and a TextView.BufferType. For example:
EditText editText = (EditText)findViewById(R.id.edit_text);
editText.setText("Google is your friend.", TextView.BufferType.EDITABLE);
Or
Use +, the string concatenation operator:
ed = (EditText) findViewById (R.id.box);
int x = 10;
ed.setText(""+x);
or
String.valueOf(int):
ed.setText(String.valueOf(x));

How to take in two different values in android?

basically what I've tried, is to create a XML with two input types decimal. Input A and Input B, and when I click add, these values will get passed onto a class method, and that method will do so and so.
The problem I have is that I have no way of passing the value from an XML file to a java file (I think)
I spent like an hour doing the XML thing only to find out I can't do it.
Can you possibly guide me as to how I might go about doing this?

EditText mEditText1 = (EditText)findViewById(R.id.number1i);
String val1 = mEditText1.getText().toString();
EditText mEditText2 = (EditText)findViewById(R.id.number2i);
String val2 = mEditText2.getText().toString();

Your XML contains two editText and one button?
in your java file you should do:
EditText e1 = (EditText)findViewById(R.id.e1);
EditText e2= (EditText) findViewById(R.id.e2);
and in xml set onClick attribute on button (example onClick="onClick")
in code:
public void onClick(View v){
e1.getText.toString(); e2.getText.toString(); //save it to string and
you have what you want}

How to get EditText value and display it on screen through TextView?

I want to get the user input for the EditText view and display it on the screen through TextView when the Button is clicked. I also, want to know what modifications can be done on the string.xml file to do this.

I didn't get the second question, maybe you can elaborate...but for your first query.
String content = edtEditText.getText().toString(); //gets you the contents of edit text
tvTextView.setText(content); //displays it in a textview..

I'm just beginner to help you for getting edittext value to textview. Try out this code -
EditText edit = (EditText)findViewById(R.id.editext1);
TextView tview = (TextView)findViewById(R.id.textview1);
String result = edit.getText().toString();
tview.setText(result);
This will get the text which is in EditText Hope this helps you.

EditText ein=(EditText)findViewById(R.id.edittext1);
TextView t=new TextView(this);
t.setText("Your Text is="+ein.getText());
setContentView(t);

bb.setOnClickListener(
new View.OnClickListener()
{
public void onClick(View view)
{
String s1=tt.getText().toString();
tv.setText(s1);
}
}
);

First get the text from edit text view
edittext.getText().toString()
and Store the obtained text in a string, say value.
value = edittext.getText().toString()
Then set value as the text for textview.
textview.setText(value)

yesButton.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View arg0) {
eiteText=(EditText)findViewById(R.id.nameET);
String result=eiteText.getText().toString();
Log.d("TAG",result);
}
});

Easiest way to get text from the user:
EditText Variable1 = findViewById(R.id.enter_name);
String Variable2 = Variable1.getText().toString();

in "String.xml" you can notice any String or value you want to use, here are two examples:
<string name="app_name">My Calculator App
</string>
<color name="color_menu_home">#ffcccccc</color>
Used for the layout.xml: android:text="#string/app_name"
The advantage: you can use them as often you want, you only need to link them in your Layout-xml, and you can change the String-Content easily in the strings.xml, without searching in your source-code for the right position.
Important for changing language, you only need to replace the strings.xml - file

Use the following code when clicked on the button :
String value = edittext.getText().toString().trim(); //get text from editText
textView.setText(value); //setText in a textview
Hope to be useful to you.

Try this->
EditText text = (EditText) findViewById(R.id.text_input);
Editable name = text.getText();
Editable is the return data type of getText() method it will handle both
string and integer values

First get the value from edit text in a String variable
String value = edttxt.getText().toString();
Then set that value to textView
txtview.setText(value);
Where edttxt refers to edit text field in XML file
and txtview refers to textfield in XML file to show the value
