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
This question is related to
java
android
android-edittext
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);
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 :) )
From the xml:
android:text="yourtext"
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("");
}
}
});
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");
We wish there is a default value attribute in each view of android views or group view in future versions of SDK. but to overcome that, simply before submission, check if the view is empty equal true, then assign a default value
example:
/* add 0 as default numeric value to a price field when skipped by a user,
in order to avoid parsing error of empty or improper format value. */
if (Objects.requireNonNull(edPrice.getText()).toString().trim().isEmpty())
edPrice.setText("0");
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");
}
}
Use android android:hint for set default value or android:text
