java – Android – default value in editText

Posted by: admin April 23, 2020 Leave a comment

Questions:

In my app I have an edit user details page and I want to display the current name, email address etc in the corresponding editText fields and then the user can just erase that and enter a new one if they want.

Is there a way to do this? Thanks for any help

How to&Answers:

You can use EditText.setText(...) to set the current text of an EditText field.

Example:

yourEditText.setText(currentUserName);

Answer:

There is the hint feature? You can use the setHint() to set it, or set it in XML (though you probably don’t want that, because the XML doesn’t ‘know’ the name/adress of your user 🙂 )

Answer:

From the xml:

  android:text="yourtext"

Answer:

You can use text property in your xml file for particular Edittext fields.
For example :

<EditText
    android:id="@+id/ET_User"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:text="yourusername"/>

like this all Edittext fields contains text whatever u want,if user wants to change particular Edittext field he remove older text and enter his new text.

In Another way just you get the particular Edittext field id in activity class and set text to that one.

Another way = programmatically

Example:

EditText username=(EditText)findViewById(R.id.ET_User);

username.setText("jack");

Answer:

First you need to load the user details somehow

Then you need to find your EditText if you don’t have it-

EditText et = (EditText)findViewById(R.id.youredittext);

after you’ve found your EditText, call

et.setText(theUserName);

Answer:

You can do it in this way

private EditText nameEdit;
private EditText emailEdit;
private String nameDefaultValue = "Your Name";
private String emailDefaultValue = "[email protected]";

and inside onCreate method

nameEdit = (EditText) findViewById(R.id.name);
    nameEdit.setText(nameDefaultValue); 
    nameEdit.setOnTouchListener( new OnTouchListener() {

        @Override
        public boolean onTouch(View v, MotionEvent event) {
            if (nameEdit.getText().toString().equals(nameDefaultValue)){
                nameEdit.setText("");
            }
            return false;
        }
    });

    nameEdit.setOnFocusChangeListener(new OnFocusChangeListener() {

        @Override
        public void onFocusChange(View v, boolean hasFocus) {               
            if(!hasFocus && TextUtils.isEmpty(nameEdit.getText().toString())){
                nameEdit.setText(nameDefaultValue);
            } else if (hasFocus && nameEdit.getText().toString().equals(nameDefaultValue)){
                nameEdit.setText("");
            }
        }
    });     

    emailEdit = (EditText)findViewById(R.id.email);
    emailEdit.setText(emailDefaultValue);   
    emailEdit.setOnFocusChangeListener(new OnFocusChangeListener() {

        @Override
        public void onFocusChange(View v, boolean hasFocus) {               
            if(!hasFocus && TextUtils.isEmpty(emailEdit.getText().toString())){
                emailEdit.setText(emailDefaultValue);
            } else if (hasFocus && emailEdit.getText().toString().equals(emailDefaultValue)){
                emailEdit.setText("");
            }
        }
    });

Answer:

 public class Main extends Activity {
    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
        EditText et = (EditText) findViewById(R.id.et);
        EditText et_city = (EditText) findViewById(R.id.et_city);
        // Set the default text of second EditText widget
        et_city.setText("USA");
 }
}
