EditText with default value

I use bootstrap with an .input-group-addon to prepend or append elements to a single form element like the TextArea input type of form. Prepend simple means it shows it contains value disabled from editing by a user.

How can I do this in my andriod app? It is with my XML or what? Please help...

I think following code will help you to do so.

Solution 1

TextView will show only prefix text, and EditText can be of user's choice.

<LinearLayout
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:orientation="horizontal"
    android:background="@android:color/white" >

    <TextView
        android:id="@+id/txtTitle"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:text="http://"
        android:textColor="@android:color/darker_gray" />

    <EditText 
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:background="@android:color/white"
        android:text="www.google.com"
        />
</LinearLayout>

In above layout, you will see TextView having your default text, but user is only able to write in EditText. So user will not have any idea about such trick.

Solution 2

final EditText edt = (EditText) findViewById(R.id.editText1);

edt.setText("http://");
Selection.setSelection(edt.getText(), edt.getText().length());


edt.addTextChangedListener(new TextWatcher() {

    @Override
    public void onTextChanged(CharSequence s, int start, int before, int count) {
        // TODO Auto-generated method stub

    }

    @Override
    public void beforeTextChanged(CharSequence s, int start, int count,
            int after) {
        // TODO Auto-generated method stub

    }

    @Override
    public void afterTextChanged(Editable s) {
        if(!s.toString().contains("http://")){
            edt.setText("http://");
            Selection.setSelection(edt.getText(), edt.getText().length());
        }
    }
});

This solution will not allow user to remove "http://" from its EditText input.

EditText extends TextView which extend View class. And View.java class has method setText which pretty much works for every view which extends View.java.

Conclustion

EditText.setText("your Text here"); //set default value

EditText.setHint("your Text here"); //set hint

In Xml

 android:text="@string/yourStringText"
