[android] How To Set Text In An EditText

How can I set the text of an EditText?

Solution in Android Java:

1. Start your EditText, the ID is come to your xml id.

   EditText myText = (EditText)findViewById(R.id.my_text_id);
   

2. in your OnCreate Method, just set the text by the name defined.

   String text = "here put the text that you want"
   

3. use setText method from your editText.

   myText.setText(text); //variable from point 2
   

String text = "Example";
EditText edtText = (EditText) findViewById(R.id.edtText);
edtText.setText(text);

Check it out EditText accept only String values if necessary convert it to string.

If int, double, long value, do:

String.value(value);

String string="this is a text";
editText.setText(string)

I have found String to be a useful Indirect Subclass of CharSequence

http://developer.android.com/reference/android/widget/TextView.html find setText(CharSequence text)

http://developer.android.com/reference/java/lang/CharSequence.html

editTextObject.setText(CharSequence)

http://developer.android.com/reference/android/widget/TextView.html#setText(java.lang.CharSequence)

You can set android:text="your text";

<EditText
    android:id="@+id/editTextName"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:text="@string/intro_name"/>

If you want to set text at design time in xml file just simple android:text="username" add this property.

<EditText
    android:id="@+id/edtUsername"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:text="username"/>

If you want to set text programmatically in Java

EditText edtUsername = findViewById(R.id.edtUsername);
edtUsername.setText("username");

and in kotlin same like java using getter/setter

edtUsername.setText("username")

But if you want to use .text from principle then

edtUsername.text = Editable.Factory.getInstance().newEditable("username")

because of EditText.text requires an editable at firstplace not String

Use +, the string concatenation operator:

 ed = (EditText) findViewById (R.id.box);
    int x = 10;
    ed.setText(""+x);

or use

String.valueOf(int):
ed.setText(String.valueOf(x));

or use

Integer.toString(int):
ed.setText(Integer.toString(x));

You need to:

1. Declare the EditText in the xml file
2. Find the EditText in the activity
3. Set the text in the EditText

This is the solution in Kotlin

val editText: EditText = findViewById(R.id.main_et_name)
    editText.setText("This is a text.")
